hi
Is there a way we can select for a particular word from all the columns in a particular table rather than specifying every column in a where statemet
I ahve a table with 1 coulmns a-z, and i am trying to find the word test in all the columns, as of now i am using
select * from 1 where
a like '%Test%' or b like '%test%' and so on
can i use any other meathod for this select where all column donot have to be specified fo that table

2 approaches that you might want to try that I can think of off the top of my head.
1. where a + b + c + d + c ... like '%test%' ie concatenate all of the columns that you are searching for together. Very inefficient.
2. Set up full-text indexing on the table for the columns that you are searching and then use Where Contains(*,'test')
Hope that this provides a little help to get you in the right direction. For information on Full-Text indexing http://msdn.microsoft.com/en-us/library/ms142571.aspx

thanks Rich
concatenation seems to be my only option as full text indexing is not set up on the DB where i am trying to use contains
is there any other way i can accomplish this

here's something i put together a long time ago; this requires one tablescan for the EXISTS() of every table that has a char/varchar/nchar/nvarchar column in it's definition...
so if you have any MillionBillionRow tables, you better not run this on production.
if it finds anything that matches, it produces a SQL you can run separately so you can review the results:
Also, i never bothered to update it for SQL 2005 + to consider schema names...it's just assuming everything is dbo.
example results:
SELECT * FROM [CMCONTACT] WHERE [BIRTHDAY] LIKE '%TEST%' OR [BUSADDRESS] LIKE '%TEST%' OR [BUSADDRESS2] LIKE '%TEST%' OR [BUSEMAIL] LIKE '%TEST%' OR [BUSFAX] LIKE '%TEST%' OR [BUSPHONE] LIKE '%TEST%' OR [BUSPHONEEXT] LIKE '%TEST%' OR [BUSZIPCODE] LIKE '%TEST%' OR [CELLPHONE] LIKE '%TEST%' OR [EDITEDBY] LIKE '%TEST%' OR [FIRSTNAME] LIKE '%TEST%' OR [IDNUMBER] LIKE '%TEST%' OR [LASTNAME] LIKE '%TEST%' OR [MIDDLENAME] LIKE '%TEST%' OR [PERADDRESS] LIKE '%TEST%' OR [PERADDRESS2] LIKE '%TEST%' OR [PEREMAIL] LIKE '%TEST%' OR [PERPHONE] LIKE '%TEST%' OR [PERZIPCODE] LIKE '%TEST%' OR [SALUTATION] LIKE '%TEST%' OR [TITLE] LIKE '%TEST%'
the procedure:
DROP PROCEDURE UGLYSEARCH
