i have a table which contains comma separated values some thing like
id locs
1 a,s,d,f
2 s,d,f,a
3 d,s,a,f
4 d,f,g,a
5 a,s,e
6 f,d
i need out put as 1,2,3,6 in sql server when i have taken comma separated string of id 1.
that means i have taken locs of id 1 and separated with comma, now i want all the ids which contains the separated values of id 1.
Note: I know i don't have to keep comma separated values in table but its happened.
Hope i was clear with my question.
declare #tb table (id int, locs varchar(50))
insert into #tb values(1, 'a,s,d,f'),
(2,'s,d,f,a'),
(3,'d,s,a,f'),
(4,'d,f,g,a'),
(5,'a,s,e'),
(6,'f,d')
declare #cta varchar(20)='s,d,f,a'
;with cte0(id,col2)
as
(
select id,t.c.value('.','varchar(max)') as col2 from (select id,x= cast('<t>'+replace(locs,',','</t><t>') +'</t>' as xml) from #tb) a cross apply x.nodes('/t') t(c)
)
select distinct id from cte0 where #cta like '%'+col2+'%' and id not in( select distinct id from cte0 where #cta not like '%'+col2+'%')
If I understand you correctly, you need to return the id value of all the rows that has at least one of the comma separated values from the locs column of the row you selected. Since this is a poor database design there can only be an ugly solution to this problem.
Start by creating a user defined function to split a comma separated values into a table. there are many ways to do it, this is the first that google found.
DECLARE #Values varchar(max)
SELECT #Values = Locs
FROM Table WHERE Id = #Id
SELECT Id
FROM Table INNER JOIN dbo.Split(#Values) SplitedString
ON( '%,'+ SplitedString.s+',%' LIKE ',' + Locs + ',')

I have the following requirement.
I have an XML variable of values.
I now should insert the values for this XML variable to a table (Table A), but need to check if the items (one by one) in the XML variable are already present in another table (Table B) and the count of that individual item present in table B is only once.
If more than once/ or not present in Table B, do not insert into the main table - Table A.
How to achieve this without using loops.
Declare #Names xml
set #Names ='<List><CNames>One</CNames><CNames>Two</CNames></List>'
**When used below xml variable of values become a column of values :**
SELECT tbl.colname.value('text()[1]','varchar(10)') AS CN
FROM #Names ('/List/CNames') tbl(colname);
CN
-------
One
Two
Now in Table B -- have to check if the items 'One' and 'Two' are present, if present are they present only once.
Tired using while loops which works fine, but want to achieve without loop.
Since you already have a selection of your rows to evaluate (#values in my solution), I started from there.
Sample data
-- existing table and data
declare #data table
(
CN nvarchar(10)
);
insert into #data (CN) values
('One'),
('Three'),
('Three');
-- new values extracted from XML
declare #values table
(
CN nvarchar(10)
);
insert into #values (CN) values
('One'), -- exists 1x and will be inserted
('Two'), -- does not exist and will not be inserted
('Three'); -- exists 2x and will not be inserted
Solution
insert into #data (CN)
select v.CN
from #values v
cross apply ( select count(1) as 'Cnt'
from #data d
where d.CN = v.CN ) c
where c.Cnt = 1;
Result
select d.CN
from #data d
order by d.CN;
CN
----------
One
One --> new inserted value

I am trying to create a simple table join on columns from two tables that are equivalent but not exact matches. For example, the row value in table A might be "Georgia Production" and the corresponding row value in table B might be "Georgia Independent Production Co".
I first tried a wild card in the join like this:
select BOLFlatFile.*, customers.City, customers.FEIN_Registration_No, customers.ST
from BOLFlatFile
Left Join Customers on (customers.Name Like '%'+BOLFlatFile.Customer+'%');
and this works great for 90% of the data. However, If the string in table A does not exactly appear in Table B, it returns null.
So back to the above example, if the value for table A were "Georgia Independent", it would work, but if it were "Georgia Production, it would not.
This might be a complicated way of still being wrong, but this works with the sample I've mocked up.
The assumption is that because you are "wildcard searching" a string from one table to another, I am assuming that all of the words in the first table column appear in the second table column, which means by default that the second table column will always have a longer string in it than the first table column.
the second assumption is that there is a unique id on the first table, if there is not then you can create one by using the row_number function and ordering on your string column.
The approach below firstly creates some sample data (I've used tablea and tableb to represent your tables).
Then a dummy table is created to store the uniqueid for your first table and the string column.
Next a loop is invoked to iterate across the string in the dummy table and insert the unique id and the first section of the string followed by a space into the handler table which is what you will use to join the 2 target tables together.
The next section joins the first table to the handler table using the unique id and then joins the second table to the handler table on the key words longer than 3 letters (avoiding "the" "and" etc) joining back to the first table using the assumption that the string in table b is longer than table a (because you are looking for instances of each word in table a column in the corresponding column of table b hence the assumption).
declare #tablea table (
id int identity(1,1),
helptext nvarchar(50)
);
declare #tableb table (
id int identity(1,1),
helptext nvarchar(50)
);
insert #tablea (helptext)
values
('Text to find'),
('Georgia Production'),
('More to find');
insert #tableb (helptext)
values
('Georgia Independent Production'),
('More Text to Find'),
('something Completely different'),
('Text to find');
declare #stringtable table (
id int,
string nvarchar(50)
);
declare #stringmatch table (
id int,
stringmatch nvarchar(20)
);
insert #stringtable (id, string)
select id, helptext from #tablea;
update #stringtable set string = string + ' ';
while exists (select 1 from #stringtable)
begin
insert #stringmatch (id, stringmatch)
select id, substring(string,1,charindex(' ',string)) from #stringtable;
update #stringmatch set stringmatch = ltrim(rtrim(stringmatch));
update #stringtable set string=replace(string, stringmatch, '') from #stringtable tb inner join #stringmatch ma
on tb.id=ma.id and charindex(ma.stringmatch,tb.string)>0;
update #stringtable set string=LTRIM(string);
delete from #stringtable where string='' or string is null;
end
select a.*, b.* from #tablea a inner join #stringmatch m on a.id=m.id
inner join #tableb b on CHARINDEX(m.stringmatch,b.helptext)>0 and len(b.helptext)>len(a.helptext);
It all depends how complex you want to make this matching. There is various ways of matching these strings and some may work better than others. Below is an example of how you can split the names in your BOLFlatFile and Customers tables into separate words by using string_split.
The example below will match anything where all the words in the BOLFlatFile customer field are contained within the customers name field (note: it won't take into account ordering of the strings).
The code below will match the first two strings as expected, but not the last two sample strings.
CREATE TABLE BOLFlatFile
(
[customer] NVARCHAR(500)
)
CREATE TABLE Customers
(
[name] NVARCHAR(500)
)
INSERT INTO Customers VALUES ('Georgia Independent Production Co')
INSERT INTO BOLFlatFile VALUES ('Georgia Production')
INSERT INTO Customers VALUES ('Test String 1')
INSERT INTO BOLFlatFile VALUES ('Test 1')
INSERT INTO Customers VALUES ('Test String 2')
INSERT INTO BOLFlatFile VALUES ('Test 3')
;with BOLFlatFileSplit
as
(
SELECT *,
COUNT(*) OVER(PARTITION BY [customer]) as [WordsInName]
FROM
BOLFlatFile
CROSS APPLY
STRING_SPLIT([customer], ' ')
),
CustomerSplit as
(
SELECT *
FROM
Customers
CROSS APPLY
STRING_SPLIT([name], ' ')
)
SELECT
a.Customer,
b.name
FROM
CustomerSplit b
INNER JOIN
BOLFlatFileSplit a
ON
a.value = b.value
GROUP BY
a.Customer, b.name
HAVING
COUNT(*) = MAX([WordsInName])
I have a varchar column, populated by another process where I have no control over, that is filled with comma separated values.
Now I need to find all rows where part of this column exists in that same column, in another row
example
declare #table table (value varchar(50))
insert into #table values ('NB,BD,FR'), ('BD,GK'), ('SL,SR')
select * from #table
so the table contains
value
-----
NB,BD,FR
BD,GK
SL,SR
from the example above I would like to get
value
-----
NB,BD,FR
BD,GK
Because there is a value (in this case BD but can be anything) present in both rows
Can this be done in sql?
You could use clunky XML manipulation to convert comma separated values to rows:
DECLARE #table TABLE (value VARCHAR(50));
INSERT INTO #table VALUES
('NB,BD,FR'),
('BD,GK'),
('SL,SR');
WITH cte AS (
SELECT value, node.value('.', 'varchar(10)') AS substr
FROM #table
CROSS APPLY (SELECT CAST('<x>' + REPLACE(value, ',', '</x>,<x>') + '</x>' AS XML)) AS x(doc)
CROSS APPLY doc.nodes('/x') AS n(node)
)
-- use your favorite technique to find the duplicate
SELECT value
FROM cte AS m
WHERE EXISTS (
SELECT 1
FROM cte AS x
WHERE value <> m.value AND substr = m.substr
)
The CAST(... AS XML) part assumes that your data does not contain characters that have special meaning in XML. The nodes method will convert one row to many, rest is straight forward.
This is the wrong data structure. Don't store values in strings!
declare #table table (id int, value varchar(50));
insert into #table
values (1, 'NB'), (1, 'BD'), (1, 'FR'),
(2, 'BD'), (2, 'GK'),
(3, 'SL'), (3, 'SR');
Then you can get what you want using window functions:
select id, value
from (select t.*, max(cnt) over (partition by id) as max_cnt
from (select t.*, count(*) over (partition by value) as cnt
from #table t
) t
) t
where max_cnt >= 2
I have a table with Primary key and auto incremented column lets say "HeaderFieldID".
Now i want to get the records as per the HeaderFieldID values.
Ex:
select *
from tblHeaderField
where HeaderFieldID in (2,1,3,4,6,5)
But,by default I am getting the records by HeaderFieldID asc order. But I want records as per the given HeaderFieldID's only.
Original Table
HeaderFieldID HFName DisplayName
1 OrgName1 disp1
2 OrgName2 disp2
3 OrgName3 disp3
4 OrgName4 disp4
5 OrgName5 disp5
6 OrgName6 disp6
Thanks in Advance
I don't know if you can order by IN, because you don't know order.
So first I would split data into rows from IN and then join it to your table.
DECLARE #table TABLE (ID INT IDENTITY(1,1) NOT NULL, NR INT)
--Prodvide data to lookup
DECLARE #givenText VARCHAR(100) = '2,1,3,4,5,6,7,8,9,10,11,12,13,14,15'
-- Split requested string into rows and add unique number
;WITH xmlData (xmlData) AS (
SELECT CAST('<x>'+REPLACE(#givenText, ',', '</x><x>')+'</x>' AS XML) AS xmlData
)
INSERT INTO #table (NR)
SELECT x.value('.','INT') AS NR
FROM xmlData
CROSS APPLY xmlData.xmlData.nodes('//x') AS func(x)
--Join tables to get result
SELECT tHF.*
FROM tblHeaderField AS tHF
INNER JOIN #table AS T
ON T.NR = tHF.HeaderFieldID
ORDER BY T.ID
Isn't clear where does this list come from (as a parameter of a stored procedure or hardcoded in the SQL statement?). Try this query:
select *
from tblHeaderField
where HeaderFieldID in (2,1,3,4,6,5)
ORDER BY
CHARINDEX(','+CAST(HeaderFieldID as varchar(100))+','
,',2,1,3,4,6,5,')
SQLFiddle demo
I have solved my query.
SELECT * FROM tblHeaderField
WHERE HeaderFieldID in (5,6,2,1,3,4,7,8,9,10,11,12,13,14,15)
ORDER BY CHARINDEX(CAST(HeaderFieldID AS VARCHAR), '5,6,2,1,3,4,7,8,9,10,11,12,13,14,15')
I have a table plist with a column list, which contains comma separated ids (1,2,3,4). I want the record of those members whose id is not in the comma separated list.
The best way is to split the comma seperated list into a table and then search against it.
Here is the code to split the string:
DECLARE #YourTable table (RowID int, Layout varchar(200))
INSERT #YourTable VALUES (1,'1,2,3,4')
;WITH SplitSting AS
(
SELECT
RowID,LEFT(Layout,CHARINDEX(',',Layout)-1) AS Part
,RIGHT(Layout,LEN(Layout)-CHARINDEX(',',Layout)) AS Remainder
FROM #YourTable
WHERE Layout IS NOT NULL AND CHARINDEX(',',Layout)>0
UNION ALL
SELECT
RowID,LEFT(Remainder,CHARINDEX(',',Remainder)-1)
,RIGHT(Remainder,LEN(Remainder)-CHARINDEX(',',Remainder))
FROM SplitSting
WHERE Remainder IS NOT NULL AND CHARINDEX(',',Remainder)>0
UNION ALL
SELECT
RowID,Remainder,null
FROM SplitSting
WHERE Remainder IS NOT NULL AND CHARINDEX(',',Remainder)=0
)
SELECT RowID,part FROM SplitSting ORDER BY RowID
