How can I perform this query? - sql

One of the fields in my database is a string containing multiple usernames separated by commas (ex: 'wasingej, doej, hamm, ..."). I want to do a query where a database entry (or multiple) is selected if a supplied username appears in the string containing multiple usernames.
How would I do this?

The best I could come up with is
CREATE TABLE supportContacts
(
id int identity primary key,
usernames varchar(255),
);
INSERT INTO supportContacts
(usernames)
VALUES
('Dan'),
('DAN,SCOTT'),
('Jordan,Michael,Dan'),
('Adam,Kelly,Daniel,Roger,Sue'),
('Crystal,Kari,Logan,Daniella'),
('Jon,Dan,Xerxes,Brian'),
('Samantha,Keylin,Dan')
;
SELECT * from supportContacts WHERE
usernames = 'Dan' or -- only dan
usernames LIKE 'Dan,%' or -- begins
usernames LIKE ',Dan,' or -- within
usernames LIKE '%,Dan' -- ends
It has the problem that it doesn't match on case - not an issue if your input isn't case sensitive anyway - but it is Better than Raging Bull's answer because it doesn't match the names within other names ( my fiddle shows this by not matching 'Daniella' or 'Daniel' )
http://sqlfiddle.com/#!6/72493/4

USING LIKE:
DECLARE #CONDITION VARCHAR(255)
SET #CONDITION = '%'' UNION SELECT * FROM TableName WHERE ColName LIKE ''%'
DECLARE #Unames VARCHAR(255) --List of username you pass from your program
SET #Unames = 'wasingej,doej,hamm' --Taking it as an example
DECLARE #FullQuery VARCHAR(255)
SET #FullQuery = 'SELECT *
FROM TableName
WHERE ColName LIKE ''%'+REPLACE(#Unames,',',#CONDITION)+'%''' --Replacing comma with #Condition
EXEC(#FullQuery)
At last, you can get your query in the variable #FullQuery like this:
SELECT * FROM TableName WHERE ColName LIKE '%wasingej%'
UNION
SELECT * FROM TableName WHERE ColName LIKE '%doej%'
UNION
SELECT * FROM TableName WHERE ColName LIKE '%hamm%'
See example in SQL Fiddle.

How to match an array of substrings to db [duplicate]

In SQL I (sadly) often have to use "LIKE" conditions due to databases that violate nearly every rule of normalization. I can't change that right now. But that's irrelevant to the question.
Further, I often use conditions like WHERE something in (1,1,2,3,5,8,13,21) for better readability and flexibility of my SQL statements.
Is there any possible way to combine these two things without writing complicated sub-selects?
I want something as easy as WHERE something LIKE ('bla%', '%foo%', 'batz%') instead of this:
WHERE something LIKE 'bla%'
OR something LIKE '%foo%'
OR something LIKE 'batz%'
I'm working with SQl Server and Oracle here but I'm interested if this is possible in any RDBMS at all.
There is no combination of LIKE & IN in SQL, much less in TSQL (SQL Server) or PLSQL (Oracle). Part of the reason for that is because Full Text Search (FTS) is the recommended alternative.
Both Oracle and SQL Server FTS implementations support the CONTAINS keyword, but the syntax is still slightly different:
Oracle:
WHERE CONTAINS(t.something, 'bla OR foo OR batz', 1) > 0
SQL Server:
WHERE CONTAINS(t.something, '"bla*" OR "foo*" OR "batz*"')
The column you are querying must be full-text indexed.
Reference:
Building Full-Text Search Applications with Oracle Text
Understanding SQL Server Full-Text
If you want to make your statement easily readable, then you can use REGEXP_LIKE (available from Oracle version 10 onwards).
An example table:
SQL> create table mytable (something)
2 as
3 select 'blabla' from dual union all
4 select 'notbla' from dual union all
5 select 'ofooof' from dual union all
6 select 'ofofof' from dual union all
7 select 'batzzz' from dual
8 /
Table created.
The original syntax:
SQL> select something
2 from mytable
3 where something like 'bla%'
4 or something like '%foo%'
5 or something like 'batz%'
6 /
SOMETH
------
blabla
ofooof
batzzz
3 rows selected.
And a simple looking query with REGEXP_LIKE
SQL> select something
2 from mytable
3 where regexp_like (something,'^bla|foo|^batz')
4 /
SOMETH
------
blabla
ofooof
batzzz
3 rows selected.
BUT ...
I would not recommend it myself due to the not-so-good performance. I'd stick with the several LIKE predicates. So the examples were just for fun.
you're stuck with the
WHERE something LIKE 'bla%'
OR something LIKE '%foo%'
OR something LIKE 'batz%'
unless you populate a temp table (include the wild cards in with the data) and join like this:
FROM YourTable y
INNER JOIN YourTempTable t On y.something LIKE t.something
try it out (using SQL Server syntax):
declare #x table (x varchar(10))
declare #y table (y varchar(10))
insert #x values ('abcdefg')
insert #x values ('abc')
insert #x values ('mnop')
insert #y values ('%abc%')
insert #y values ('%b%')
select distinct *
FROM #x x
WHERE x.x LIKE '%abc%'
or x.x LIKE '%b%'
select distinct x.*
FROM #x x
INNER JOIN #y y On x.x LIKE y.y
OUTPUT:
x
----------
abcdefg
abc
(2 row(s) affected)
x
----------
abc
abcdefg
(2 row(s) affected)
With PostgreSQL there is the ANY or ALL form:
WHERE col LIKE ANY( subselect )
or
WHERE col LIKE ALL( subselect )
where the subselect returns exactly one column of data.
Another solution, should work on any RDBMS:
WHERE EXISTS (SELECT 1
FROM (SELECT 'bla%' pattern FROM dual UNION ALL
SELECT '%foo%' FROM dual UNION ALL
SELECT 'batz%' FROM dual)
WHERE something LIKE pattern)
The inner select can be replaced by another source of patterns like a table (or a view) in this way:
WHERE EXISTS (SELECT 1
FROM table_of_patterns t
WHERE something LIKE t.pattern)
table_of_patterns should contain at least a column pattern, and can be populated like this:
INSERT INTO table_of_patterns(pattern) VALUES ('bla%');
INSERT INTO table_of_patterns(pattern) VALUES ('%foo%');
INSERT INTO table_of_patterns(pattern) VALUES ('batz%');
I would suggest using a TableValue user function if you'd like to encapsulate the Inner Join or temp table techniques shown above. This would allow it to read a bit more clearly.
After using the split function defined at: http://www.logiclabz.com/sql-server/split-function-in-sql-server-to-break-comma-separated-strings-into-table.aspx
we can write the following based on a table I created called "Fish" (int id, varchar(50) Name)
SELECT Fish.* from Fish
JOIN dbo.Split('%ass,%e%',',') as Splits
on Name like Splits.items //items is the name of the output column from the split function.
Outputs
1 Bass
2 Pike
7 Angler
8 Walleye
I'm working with SQl Server and Oracle here but I'm interested if this is possible in any RDBMS at all.
Teradata supports LIKE ALL/ANY syntax:
ALL every string in the list.
ANY any string in the list.
┌──────────────────────────────┬────────────────────────────────────┐
│ THIS expression … │ IS equivalent to this expression … │
├──────────────────────────────┼────────────────────────────────────┤
│ x LIKE ALL ('A%','%B','%C%') │ x LIKE 'A%' │
│ │ AND x LIKE '%B' │
│ │ AND x LIKE '%C%' │
│ │ │
│ x LIKE ANY ('A%','%B','%C%') │ x LIKE 'A%' │
│ │ OR x LIKE '%B' │
│ │ OR x LIKE '%C%' │
└──────────────────────────────┴────────────────────────────────────┘
EDIT:
jOOQ version 3.12.0 supports that syntax:
Add synthetic [NOT] LIKE ANY and [NOT] LIKE ALL operators
A lot of times, SQL users would like to be able to combine LIKE and IN predicates, as in:
SELECT *
FROM customer
WHERE last_name [ NOT ] LIKE ANY ('A%', 'E%') [ ESCAPE '!' ]
The workaround is to manually expand the predicate to the equivalent
SELECT *
FROM customer
WHERE last_name LIKE 'A%'
OR last_name LIKE 'E%'
jOOQ could support such a synthetic predicate out of the box.
PostgreSQL LIKE/ILIKE ANY (ARRAY[]):
SELECT *
FROM t
WHERE c LIKE ANY (ARRAY['A%', '%B']);
SELECT *
FROM t
WHERE c LIKE ANY ('{"Do%", "%at"}');
db<>fiddle demo
Snowflake also supports LIKE ANY/LIKE ALL matching:
LIKE ANY/ALL
Allows case-sensitive matching of strings based on comparison with one or more patterns.
<subject> LIKE ANY (<pattern1> [, <pattern2> ... ] ) [ ESCAPE <escape_char> ]
Example:
SELECT *
FROM like_example
WHERE subject LIKE ANY ('%Jo%oe%','T%e')
-- WHERE subject LIKE ALL ('%Jo%oe%','J%e')
Use an inner join instead:
SELECT ...
FROM SomeTable
JOIN
(SELECT 'bla%' AS Pattern
UNION ALL SELECT '%foo%'
UNION ALL SELECT 'batz%'
UNION ALL SELECT 'abc'
) AS Patterns
ON SomeTable.SomeColumn LIKE Patterns.Pattern
One approach would be to store the conditions in a temp table (or table variable in SQL Server) and join to that like this:
SELECT t.SomeField
FROM YourTable t
JOIN #TempTableWithConditions c ON t.something LIKE c.ConditionValue
I have a simple solution, that works in postgresql at least, using like any followed by the list of regex. Here is an example, looking at identifying some antibiotics in a list:
select *
from database.table
where lower(drug_name) like any ('{%cillin%,%cyclin%,%xacin%,%mycine%,%cephal%}')
u can even try this
Function
CREATE FUNCTION [dbo].[fn_Split](#text varchar(8000), #delimiter varchar(20))
RETURNS #Strings TABLE
(
position int IDENTITY PRIMARY KEY,
value varchar(8000)
)
AS
BEGIN
DECLARE #index int
SET #index = -1
WHILE (LEN(#text) > 0)
BEGIN
SET #index = CHARINDEX(#delimiter , #text)
IF (#index = 0) AND (LEN(#text) > 0)
BEGIN
INSERT INTO #Strings VALUES (#text)
BREAK
END
IF (#index > 1)
BEGIN
INSERT INTO #Strings VALUES (LEFT(#text, #index - 1))
SET #text = RIGHT(#text, (LEN(#text) - #index))
END
ELSE
SET #text = RIGHT(#text, (LEN(#text) - #index))
END
RETURN
END
Query
select * from my_table inner join (select value from fn_split('ABC,MOP',','))
as split_table on my_table.column_name like '%'+split_table.value+'%';
Starting with 2016, SQL Server includes a STRING_SPLIT function. I'm using SQL Server v17.4 and I got this to work for me:
DECLARE #dashboard nvarchar(50)
SET #dashboard = 'P1%,P7%'
SELECT * from Project p
JOIN STRING_SPLIT(#dashboard, ',') AS sp ON p.ProjectNumber LIKE sp.value
May be you think the combination like this:
SELECT *
FROM table t INNER JOIN
(
SELECT * FROM (VALUES('bla'),('foo'),('batz')) AS list(col)
) l ON t.column LIKE '%'+l.Col+'%'
If you have defined full text index for your target table then you may use this alternative:
SELECT *
FROM table t
WHERE CONTAINS(t.column, '"bla*" OR "foo*" OR "batz*"')
I was also wondering for something like that. I just tested using a combination of SUBSTRING and IN and it is an effective solution for this kind of problem. Try the below query :
Select * from TB_YOUR T1 Where SUBSTRING(T1.Something, 1,3) IN ('bla', 'foo', 'batz')
In Oracle you can use a collection in the following way:
WHERE EXISTS (SELECT 1
FROM TABLE(ku$_vcnt('bla%', '%foo%', 'batz%'))
WHERE something LIKE column_value)
Here I have used a predefined collection type ku$_vcnt, but you can declare your own one like this:
CREATE TYPE my_collection AS TABLE OF VARCHAR2(4000);
I may have a solution for this, although it will only work in SQL Server 2008 as far as I know. I discovered that you can use the row-constructor described in https://stackoverflow.com/a/7285095/894974 to join a 'fictional' table using a like clause.
It sounds more complex then it is, look:
SELECT [name]
,[userID]
,[name]
,[town]
,[email]
FROM usr
join (values ('hotmail'),('gmail'),('live')) as myTable(myColumn) on email like '%'+myTable.myColumn+'%'
This will result in all users with an e-mail adres like the ones provided in the list.
Hope it's of use to anyone. The problem had been bothering me a while.
For Sql Server you can resort to Dynamic SQL.
Most of the time in such situations you have the parameter of IN clause based on some data from database.
The example below is a little "forced", but this can match various real cases found in legacy databases.
Suppose you have table Persons where person names are stored in a single field PersonName as FirstName + ' ' + LastName.
You need to select all persons from a list of first names, stored in field NameToSelect in table NamesToSelect, plus some additional criteria (like filtered on gender, birth date, etc)
You can do it as follows
-- #gender is nchar(1), #birthDate is date
declare
#sql nvarchar(MAX),
#subWhere nvarchar(MAX)
#params nvarchar(MAX)
-- prepare the where sub-clause to cover LIKE IN (...)
-- it will actually generate where clause PersonName Like 'param1%' or PersonName Like 'param2%' or ...
set #subWhere = STUFF(
(
SELECT ' OR PersonName like ''' + [NameToSelect] + '%'''
FROM [NamesToSelect] t FOR XML PATH('')
), 1, 4, '')
-- create the dynamic SQL
set #sql ='select
PersonName
,Gender
,BirstDate -- and other field here
from [Persons]
where
Gender = #gender
AND BirthDate = #birthDate
AND (' + #subWhere + ')'
set #params = ' #gender nchar(1),
#birthDate Date'
EXECUTE sp_executesql #sql, #params,
#gender,
#birthDate
If you are using MySQL the closest you can get is full-text search:
Full-Text Search, MySQL Documentation
This works for comma separated values
DECLARE #ARC_CHECKNUM VARCHAR(MAX)
SET #ARC_CHECKNUM = 'ABC,135,MED,ASFSDFSF,AXX'
SELECT ' AND (a.arc_checknum LIKE ''%' + REPLACE(#arc_checknum,',','%'' OR a.arc_checknum LIKE ''%') + '%'')''
Evaluates to:
AND (a.arc_checknum LIKE '%ABC%' OR a.arc_checknum LIKE '%135%' OR a.arc_checknum LIKE '%MED%' OR a.arc_checknum LIKE '%ASFSDFSF%' OR a.arc_checknum LIKE '%AXX%')
If you want it to use indexes, you must omit the first '%' character.
In Oracle RBDMS you can achieve this behavior using REGEXP_LIKE function.
The following code will test if the string three is present in the list expression one|two|three|four|five (in which the pipe "|" symbol means OR logic operation).
SELECT 'Success !!!' result
FROM dual
WHERE REGEXP_LIKE('three', 'one|two|three|four|five');
RESULT
---------------------------------
Success !!!
1 row selected.
Preceding expression is equivalent to:
three=one OR three=two OR three=three OR three=four OR three=five
So it will succeed.
On the other hand, the following test will fail.
SELECT 'Success !!!' result
FROM dual
WHERE REGEXP_LIKE('ten', 'one|two|three|four|five');
no rows selected
There are several functions related to regular expressions (REGEXP_*) available in Oracle since 10g version. If you are an Oracle developer and interested this topic this should be a good beginning Using Regular Expressions with Oracle Database.
No answer like this:
SELECT * FROM table WHERE something LIKE ('bla% %foo% batz%')
In oracle no problem.
In Teradata you can use LIKE ANY ('%ABC%','%PQR%','%XYZ%'). Below is an example which has produced the same results for me
--===========
-- CHECK ONE
--===========
SELECT *
FROM Random_Table A
WHERE (Lower(A.TRAN_1_DSC) LIKE ('%american%express%centurion%bank%')
OR Lower(A.TRAN_1_DSC) LIKE ('%bofi%federal%bank%')
OR Lower(A.TRAN_1_DSC) LIKE ('%american%express%bank%fsb%'))
;
--===========
-- CHECK TWO
--===========
SELECT *
FROM Random_Table A
WHERE Lower(A.TRAN_1_DSC) LIKE ANY
('%american%express%centurion%bank%',
'%bofi%federal%bank%',
'%american%express%bank%fsb%')
Sorry for dredging up an old post, but it has a lot of views. I faced a similar problem this week and came up with this pattern:
declare #example table ( sampletext varchar( 50 ) );
insert #example values
( 'The quick brown fox jumped over the lazy dog.' ),
( 'Ask not what your country can do for you.' ),
( 'Cupcakes are the new hotness.' );
declare #filter table ( searchtext varchar( 50 ) );
insert #filter values
( 'lazy' ),
( 'hotness' ),
( 'cupcakes' );
-- Expect to get rows 1 and 3, but no duplication from Cupcakes and Hotness
select *
from #example e
where exists ( select * from #filter f where e.sampletext like '%' + searchtext + '%' )
Exists() works a little better than join, IMO, because it just tests each record in the set, but doesn't cause duplication if there are multiple matches.
This is possible in Postgres using like or ilike and any or all with array. This is an example that worked for me using Postgres 9:
select id, name from tb_organisation where name ilike any (array['%wembley%', '%south%']);
And this prints out:
id | name
-----+------------------------
433 | South Tampa Center
613 | South Pole
365 | Bromley South
796 | Wembley Special Events
202 | Southall
111 | Wembley Inner Space
In T-SQL, this option works but it is not very fast:
CREATE FUNCTION FN_LIKE_IN (#PROC NVARCHAR(MAX), #ITENS NVARCHAR(MAX)) RETURNS NVARCHAR(MAX) AS BEGIN
--Search an item with LIKE inside a list delimited by "," Vathaire 11/06/2019
DECLARE #ITEM NVARCHAR(MAX)
WHILE CHARINDEX(',', #ITENS) > 0 BEGIN
SET #ITEM = LEFT(#ITENS, CHARINDEX(',', #ITENS) - 1)
--IF #ITEM LIKE #PROC
IF #PROC LIKE #ITEM
RETURN #PROC --#ITEM --1
ELSE
SET #ITENS = STUFF(#ITENS, 1, LEN(#ITEM) + 1, '')
END
IF #PROC LIKE #ITENS RETURN #PROC --#ITEM --1
RETURN NULL --0
END
Query:
SELECT * FROM SYS.PROCEDURES
WHERE DBO.FN_LIKE_IN(NAME, 'PRC%,SP%') IS NOT NULL
you can do this dynamically for a large number of elements, at the expense of performance, but it works.
DECLARE #val nvarchar(256),
#list nvarchar(max) = 'one,two,three,ten,five';
CREATE table #table (FIRST_NAME nvarchar(512), LAST_NAME nvarchar(512));
CREATE table #student (FIRST_NAME nvarchar(512), LAST_NAME nvarchar(512), EMAIL
nvarchar(512));
INSERT INTO #student (FIRST_NAME, LAST_NAME, EMAIL)
SELECT 'TEST', ' redOne' ,'test.redOne#toto.com' UNION ALL
SELECT 'student', ' student' ,'student#toto.com' UNION ALL
SELECT 'student', ' two' ,'student.two#toto.com' UNION ALL
SELECT 'hello', ' ONE TWO THREE' ,'student.two#toto.com'
DECLARE check_cursor CURSOR FOR select value from STRING_SPLIT(#list,',')
OPEN check_cursor
FETCH NEXT FROM check_cursor INTO #val
WHILE ##FETCH_STATUS = 0
BEGIN
PRINT #val
IF EXISTS (select * from #student where REPLACE(FIRST_NAME, ' ','')
like '%' + #val + '%' OR REPLACE(LAST_NAME, ' ','') like '%' + #val + '%')
BEGIN
INSERT INTO #table (FIRST_NAME, LAST_NAME )
SELECT TOP 1 FIRST_NAME, LAST_NAME VALUE from #student where
REPLACE(FIRST_NAME, ' ','') like '%' + #val + '%' OR REPLACE(LAST_NAME, ' ','')
like '%' + #val + '%'
END;
FETCH NEXT FROM check_cursor INTO #val
END
CLOSE check_cursor;
DEALLOCATE check_cursor;
SELECT * FROM #table;
DROP TABLE #table;
DROP TABLE #student;
use cursor in SQL SERVER and execute for every value:
table sample:

nested select query with table name in sqlite

I am trying to select all distinct values from all tables that start with a specific name, like: 'logs_2020_12_01', 'logs_2021_01_02', ..To select all tables with this specific name is straight forward:
SELECT name FROM sqlite_master WHERE type='table' AND name LIKE 'logs_%';
The select I want for one individual table is:
SELECT DISTINCT batch FROM logs_2021_01_27;
but I cannot find a way to combine it to make the selection from all tables. I tried a couple of things but it does not work, like:
SELECT DISTINCT batch FROM (SELECT name FROM sqlite_master WHERE type='table' AND name LIKE 'logs_%')
any ideas?
thanks
What about using Dynamic SQL, stored your tables information into a temp table with id column and set it to identity.
CREATE TABLE #temp ---identity column will be used to iterate
(
id INT IDENTITY,
TableName VARCHAR(20)
)
INSERT INTO #temp
SELECT name FROM sqlite_master WHERE type='table' AND name LIKE 'logs_%';
-- choose your own results with where conditions
DECLARE #SQL VARCHAR(MAX)
DECLARE #Count INT = 1
DECLARE #Table VARCHAR(20)
WHILE #COUNT <= (SELECT COUNT(*) FROM #temp)
BEGIN
select #table = TABLENAME FROM #temp WHERE id = #Count
SELECT #sql = 'SELECT DISTINCT(batch) FROM '+ #table
PRINT #SQL
SET #Count = #Count + 1
END
after your print result looks good, change it to EXEC(#SQL), thanks
SQLite does not support dynamic sql.
You have to select the column batch from each of all the tables and combine them with UNION so the duplicates are removed:
SELECT batch FROM logs_2020_12_01 UNION
SELECT batch FROM logs_2020_12_02 UNION
......................................
SELECT batch FROM logs_2020_12_30 UNION
SELECT batch FROM logs_2020_12_31
If you don't know the full names of the tables, you can get them with this statement:
SELECT name
FROM sqlite_master
WHERE type = 'table' AND name LIKE 'logs/_%' ESCAPE '/'
and then use a programming language to construct a SELECT statement with UNION to get the results that you want.

Is there a possibility to Avoid multiple "OR" statement in Microsoft SQL?

I have a query that has to filter our results from a text field based on certain keywords used in the textline .. currently the SQL statement looks like the below.
and (name like '%Abc%') or (name like '%XYZ%') or (name like '%CSV%')...
Is there a way to avoid multiple or statements and achieve the same results?
You could put your filter keywords into a table or temp table and query them like this:
select a.*
from table_you_are_searching a
inner join temp_filter_table b
on charindex(b.filtercolumn,a.searchcolumn) <> 0
A slightly more shorthand way of doing this if you have a large amount of different patterns is to use EXISTS and a table value constructor:
SELECT *
FROM T
WHERE EXISTS
( SELECT 1
FROM (VALUES ('abc'), ('xyz'), ('csv')) m (match)
WHERE T.Name LIKE '%' + m.Match + '%'
);
A similar approach can be applied with table valued parameters. Since this is usually a requirement where people want to pass a variable number of search terms for a match it can be quite a useful approach:
CREATE TYPE dbo.ListOfString TABLE (value VARCHAR(MAX));
Then a procedure can take this type:
CREATE PROCEDURE dbo.GetMatches #List dbo.ListOfString READONLY
AS
BEGIN
SELECT *
FROM T
WHERE EXISTS
( SELECT 1
FROM #List AS l
WHERE T.Name LIKE '%' + l.value + '%'
);
END
Then you can call this procedure:
DECLARE #T dbo.ListOfString;
INSERT #T VALUES ('abc'), ('xyz'), ('csv');
EXECUTE dbo.GetMatches #T;
Just to give you another option you could also try this, an IN statement mixed with a PATINDEX:
Select *
from tbl
Where 0 not in (PATINDEX('%Abc%', name), PATINDEX('%XYZ%', name), PATINDEX('%CSV%', name))

find substrings in sql table using sql query

I have a column of "name" in my sql table. In my sql query i want to fetch all the records where column "name" is substring of my input string.
For exapmle, user enters "My name is Davivd", then I want to fetch all the records where name is David.
P.S: User may enters something like this "Its David here".
Anyone who knows please let me know. Thanku
A simple view of this would be:
DECLARE #x VARCHAR(255)
SET #x = 'My name is David'
SELECT a FROM tablex WHERE #x LIKE '%' + tablex.name + '%'
This reverses #shortspider's response.
Your question is a bit unclear, but if you have a name column you can find it as part of any string using the CHARINDEX function:
Example:
DECLARE #TABLE TABLE (ID INT IDENTITY(1,1), NAME VARCHAR(100))
INSERT INTO #TABLE(NAME)
SELECT 'DAVID' UNION ALL
SELECT 'GOLIATH' UNION ALL
SELECT 'DAVE' UNION ALL
SELECT 'MARTIN'
SELECT *
FROM #TABLE
WHERE CHARINDEX(NAME,'DID YOU EVER READ THE STORY ABOUT DAVID AND GOLIATH?') > 0
SELECT *
FROM #TABLE
WHERE CHARINDEX(NAME,'MY FAVOURITE MOVIE DIRECTOR IS MARTIN SCORCESE. I LOVE HIS GLASSES.') > 0
Try: SELECT * FROM table_name WHERE name LIKE '%David%'

How to compare two sub queries in one sql statement

I have a table tbl_Country, which contains columns called ID and Name. The Name column has multiple country names separated by comma, I want the id when I pass multiple country names to compare with Name column values. I am splitting the country names using a function - the sample query looks like this:
#country varchar(50)
SELECT *
FROM tbl_Country
WHERE (SELECT *
FROM Function(#Country)) IN (SELECT *
FROM Function(Name))
tbl_country
ID Name
1 'IN,US,UK,SL,NZ'
2 'IN,PK,SA'
3 'CH,JP'
parameter #country ='IN,SA'
i have to get
ID
1
2
NOTE: The Function will split the string into a datatable
Try this
SELECT * FROM tbl_Country C
LEFT JOIN tbl_Country C1 ON C1.Name=C.Country
Try this:
SELECT *
FROM tbl_Country C
WHERE ',' + #country + ',' LIKE '%,' + C.Name + ',%';
Basically, by specifying multiple values in a single column, you are violating the 1st NF. Therefore, the following might not be a good approach but provides the solution that you are looking for:
declare #country varchar(50)= 'IN,SA'
declare #counterend int
declare #counterstart int =1
declare #singleCountry varchar(10)
set #counterend = (select COUNT(*) from fnSplitStringList(#country))
create table #temp10(
id int
,name varchar(50))
while #counterstart<= #counterend
begin
;with cte as (
select stringliteral country
, ROW_NUMBER() over (order by stringliteral) countryseq
from fnSplitStringList(#country))
select #singleCountry = (select country FROM cte where countryseq=#counterstart)
insert into #temp10(id, name)
select * from tbl_country t1
where not exists (select id from #temp10 t2 where t1.id=t2.id)
and name like '%' + #singleCountry +'%'
set #counterstart= #counterstart+1
end
select * from #temp10
begin drop table #temp10 end
How it works: It splits the passed string and ranks it. Afterwards, it loops through all the records for every single Value(country) produced and inserts them into temptable.
try this,
select a.id FROM tbl_Country a inner join
(SELECT country FROM dbo.Function(#Country)) b on a.name=b.country
