#101301

Morning all!
If I execute the following sp:
CREATE PROCEDURE procNotesTextSearch
AS
SET NOCOUNT ON
SELECT *
FROM notescustlog INNER JOIN custlog ON notes_key = [Key]
WHERE notes_key IN
(SELECT DISTINCT notes_key FROM notescustlog WHERE CONTAINS(notes_text, ' damage '))
I get hundreds of rows returned.
If I execute the following:
CREATE PROCEDURE procNotesTextSearch @strCriteria AS varchar(100)
AS
SET NOCOUNT ON
SELECT *
FROM notescustlog INNER JOIN custlog ON notes_key = [Key]
WHERE notes_key IN
(SELECT DISTINCT notes_key FROM notescustlog WHERE CONTAINS(notes_text, ' @strCriteria '))
With EXECUTE procNotesTextSearch @strCriteria = 'damage'
I get no rows.
Isn't possible to pass a parameter into the CONTAINS clause?
Thanks
Jonathan

You have put @strCriteria in quotes, so it is searching for the literal '@strCriteria', not the contents of the variable. Just remove the quotes:-

(SELECT DISTINCT notes_key FROM notescustlog WHERE CONTAINS(notes_text, @strCriteria))

CONTAINS cannot use variables for the search condition.

You would need to build the string and execute it.

Thanks ianscarlett and simonsabin! After much frustration I am ready to fully accept Simon's position. It ain't gonna happen with a variable!

Books Online contradicts Simon's claim:

H. Use CONTAINS with variables

This example uses a variable instead of a specific search term.

USE pubs

GO

DECLARE @SearchWord varchar(30)

SET @SearchWord ='Moon'

SELECT pr_info FROM pub_info WHERE CONTAINS(pr_info, @SearchWord)

This is direct from BOL

Specifies some text to search for in column. Variables cannot be used for the search condition.

looks like a contradiction in BOL

Simon -- No surprise about BOL

I'm curious where you found your reference. Mine was simply going to the index, typing CONTAINS and scrolling to the bottom of that function.

I did play with the function a bit and couldn't get it to work even using a string. I typically send in parameters to procs and do something like:

SELECT * FROM table WHERE column LIKE '%' + @parm + '%'

(hmmm, for some reason the pluses between my %'s and parm don't show up in the preview)

Have you used CONTAINS? Does it actually work?

The information on CONTAINS was updated in the Sept. 2001 update to BOL. This may have been one of the updates. I have successfully used CONTAINS with a variable in several applications.

lambje

did the same as you, but didn't look at the example, reference is about 1/3 or the way down.
