i want to create a stored procedure that pulls a list from a table.

currently I am searching a comments field for keywords, using a like statement for each keyword, but I would like to pull the list of keywords from another table so if the keywords change i dont have to change the query.  Is this possible?

example of what i am currently doing.

select * from tblCustomerInfo
where comments like '%Test%' or comments like '%One%' or comments like '%Two%'
Comment

Sure.  Load "Test", "One", etc. into a table and then  you can do this:

SELECT *
FROM tblCustomerInfo ci
WHERE
    EXISTS(SELECT 1 FROM otherTable o WHERE ci.comments LIKE o.string)

it doesnt work, i put the keywords in a separate table and get nothing back, i test by doing this, and returned rows.

SELECT *
FROM tblCustomerInfo ci
WHERE
    EXISTS(SELECT 1 FROM KeyWords o WHERE ci.comments LIKE '%One%')

You need to put the %s in the strings in the table, NOT in the SQL SELECT.

Sorry, I should have stated:

Sure.  Load "%Test%", "%One%", etc. into a table and then do the EXISTS checks.

It's more flexible that way -- there may be times when you don't want leading and/or trailing %s.
