I am using a SQL Server database, and I am storing Malayalam names in my tables. I just want to write a query for filtering names using some Malayalam words.
SELECT * FROM table WHERE mal_Name LIKE '#word%'
#word contain Malayalam words.
How can I achieve this? Please share any ideas.
EDIT
This is my table, rm_Malayalam_name contains Malayalam name. And my Query is
SELECT *
FROM Purchase.tblRawMaterials
WHERE rm_malayalam_name LIKE '%കദളിപഴം%'
It doesn't work. The entry is there but while executing this query nothing is shown
Do you mean you want to do something like SELECT * FROM table WHERE mal_Name LIKE '%'+#word+'%'
This will work if #Word is a single word, however if you want to take in multiple words you are going to need something a bit more complex.
UPDATE:
Having seen your new edits I would suspect that the reason it is not selecting is due to the encoding
Try SELECT * FROM table WHERE mal_Name LIKE N'%'+#word+'%'
or
select * from Purchase.tblRawMaterials where rm_malayalam_name like N'%കദളിപഴം%'
I'd suggest reading up on SQL's full-text search It will almost certainly be more efficient than LIKE '%word%'
How many words will you be searching on? How big is the column? These factors might influence what the best option is.

I'm trying to make multiple like in the clause like this code but I need to shorten it because I have to repeat this code for several different conditions to create different tables. I have tried all of the solutions from here but somehow none of this works for me. I have also tried LIKE '[40101,40102,40104]%' and LIKE '[40101-40102-40104]%' but it did not work too. What should I do?
SELECT *
from table
WHERE column LIKE '40101%'
OR column LIKE '40102%'
OR column LIKE '40105%'
For these patterns you can use:
SELECT *
FROM table
WHERE column LIKE '4010[125]%'
SQL Server modestly extends LIKE patterns to include character matching.
Hello I want to display results from unrelated tables where a text string exists in a column which is common to all tables in the database.
I can get the desired result with this:
SELECT *
FROM Table1
WHERE Title LIKE '%Text%'
UNION
SELECT *
FROM Table2
WHERE Title LIKE '%Text%'`
However my question is is there a more efficient way to go about this as I need to search dozens of tbls. Thanks for any help you can give!
ps the system I am using supports most dialects but would prefer to keep it simple with SQL Server as that is what I am used to.
There is a SP script you can find online called SearchAllTables (http://vyaskn.tripod.com/search_all_columns_in_all_tables.htm).
When you call it pass in the string, it will return the tables and columns as well as the full string.
You can modify it to work with other datatypes quite easily. It's a fantastic resource for tasks exactly like yours.
I have a table called logs.lognotes, and I want to find a faster way to search for customers who do not have a specific word or phrase in the note. I know I can use "not like", but my question is, can you use DOES NOT CONTAINS to replace not like, in the same way you can use:
SELECT *
FROM table
WHERE CONTAINS (column, ‘searchword’)
Yes, you should be able to use NOT on any boolean expression, as mentioned in the SQL Server Docs here. And, it would look something like this:
SELECT *
FROM table
WHERE NOT CONTAINS (column, ‘searchword’)
To search for records that do not contain the 'searchword' in the column. And, according to
Performance of like '%Query%' vs full text search CONTAINS query
this method should be faster than using LIKE with wildcards.
You can also simply use this:
select * from tablename where not(columnname like '%value%')
I'm still a bit of a noob, so pardon if this question is a bit obvious. I did search for an answer but either couldn't understand how the answers I found applied, or simply couldn't find an answer.
I have a massive database housed on a DB2 for i server which I'm accessing using SQL through SQLExplorer (based on Squirrel SQL). The tables are very poorly documented and the first order of business is figuring out how to find my way around.
I want to write a simple query that does this:
1) Allows me to search the entire database looking for tables that include a column called "Remarks" (which contains field descriptions).
2) I then want it to search that column for a keyword.
3) I want a table returned that includes the names of the tables that include that keyword (just the name, I can look up the table alphabetically later and look inside if I need to.)
I need this search to be super lightweight, and I'm hoping the concept I describe will achieve that. Anything that eats up a lot of resources will likely anger the sys admin for the server.
Just to show I have tried (and that I am a complete noob), here's what I've got so far.
SELECT *
FROM <dbname>
WHERE Remarks LIKE '<keyword>'
Feel free to mock, I told you I'm an idiot :-).
Any help? Perhaps at least a push in the right direction?
PS - I can't seem to find a search function in SQLExplorer, if someone knows if I can perhaps use a simple search or filter to accomplish this same goal...that would be great.
You can query the system catalog to identify the tables:
SELECT TABLE_SCHEMA, TABLE_NAME, COLUMN_NAME
FROM QSYS2.SYSCOLUMNS WHERE UPPER(DBILFL) = 'REMARKS'
And then query each table individually:
SELECT * FROM TABLE_SCHEMA.TABLE_NAME WHERE Remarks LIKE '%<keyword>%'
See the LIKE predicate for details of the pattern expression.
Normally i use something like this
SELECT TABLE_SCHEMA, TABLE_NAME
,COLUMN_NAME,SYSTEM_COLUMN_NAME,COLUMN_HEADING
,DATA_TYPE, "LENGTH",NUMERIC_SCALE
FROM QSYS2.SYSCOLUMNS
WHERE UPPER(COLUMN_NAME) LIKE '%REMARK%'
#JamesA, i'm at V6R1, by default, normal user are not authorized to object QADBIFLD in QSYS
Generally, many if not most IBM i shops (especially those that use RPG) stick to 10 (or less) character schema names & table names, and have a 10 (or less) character names for 'system' column names, even if longer column names are also provided. Column text generally describes each field.
SELECT SYSTEM_TABLE_SCHEMA, SYSTEM_TABLE_NAME
,SYSTEM_COLUMN_NAME,
,DATA_TYPE, "LENGTH",NUMERIC_SCALE
,CHAR(COLUMN_TEXT)
FROM QSYS2.SYSCOLUMNS
WHERE UPPER(COLUMN_NAME) LIKE '%REMARK%'
I need to filter out records based on some text matching in nvarchar(1000) column.
Table has more than 400 thousands records and growing. For now, I am using Like condition:-
SELECT
*
FROM
table_01
WHERE
Text like '%A1%'
OR Text like '%B1%'
OR Text like '%C1%'
OR Text like '%D1%'
Is there any preferred work around?
SELECT
*
FROM
table_01
WHERE
Text like '%[A-Z]1%'
This will check if the texts contains A1, B1, C1, D1, ...
Reference to using the Like Condition in SQL Server
You can try the following if you know the exact position of your sub string:
SELECT
*
FROM
table_01
WHERE
SUBSTRING(Text,1,2) in ('B1','C1','D1')
Have a look at LIKE on msdn.
You could reduce the number filters by combining more details into a single LIKE clause.
SELECT
*
FROM
table_01
WHERE
Text like '%[ABCD]1%'
If you can create a FULLTEXT INDEX on that column of your table (that assumes a lot of research on performance and space), then you are probably going to see a big improvement on performance on text matching. You can go to this link to see what FULLTEXT SEARCH is
and this link to see how to create a FULLTEXT INDEX.
I needed to do this so that I could allow two different databases in a filter for the DatabaseName column in an SQL Server Profiler Trace Template.
All you can do is fill in the body of a Like clause.
Using the reference in John Hartscock's answer, I found out that the like clause uses a sort of limited regex pattern.
For the OP's scenario, MSMS has the solution.
Assuming I want databases ABCOne, ABCTwo, and ABCThree, I come up with what is essentially independent whitelists for each character:
Like ABC[OTT][NWH][EOR]%
Which is easily extensible to any set of strings. It won't be ironclad, that last pattern would also match ABCOwe, ABCTnr, or ABCOneHippotamus, but if you're filtering a limited set of possible values there's a good chance you can make it work.
You could alternatively use the [^] operator to present a blacklist of unacceptable characters.
