Assuming 'freetext' is a UDF then you need to qualify it with the schema name to which it belongs, typically like this:

(Course_Name = Case when ((@VarCourse_Name='') or (@VarCourse_Name is null))

Then Course_Name Else (dbo.freetext(Course_Name,@VarCourse_Name)) end)

Sorry, my mistake. This is a component of full-text searching. Is full-text search enabled? From BOL: "x Is the name of the column that has been registered for full-text searching".

what is the udf?

Eugene Elutin SSC Guru Points: 59322 More actions · Answer 5

FREETEXT is not UDF, it is in-build predicate. It cannot be used in such context.

You have used it similar to the following:

...

CASE WHEN ColA>ColB THEN ColC ELSE ColD>ColE

...

While it shoud be used like:

...

WHERE FREETEXT(ColA,'some text')

Read the BoL:

ok, Course_Name if column name , so i wroteit correctly:

Else (freetext(Course_Name,@VarCourse_Name))

but there is syntax error

As Eugene points out, this won't work because you're attempting to compare

Course_Name with (freetext(Course_Name,@VarCourse_Name)). The correct syntax is WHERE freetext(Course_Name,@VarCourse_Name).

thank you i understand what are you saying but there is another problem, and that is: maybe maybe operator send null or ' ' , so i have to check , and i have to check ir with case like what ever i wrote it before so the problem is occured

You could split it into two possible options like this:

IF @VarCourse_Name IS NULL

BEGIN

SELECT *

FROM Course

WHERE freetext(Course_Name, @VarCourse_Name)

AND Course_Id = COALESCE(Course_Id, NULLIF(@VarCourse_Id, 0))

AND ...

END

ELSE

BEGIN

SELECT *

FROM Course

WHERE 1 = 1

AND Course_Id = COALESCE(Course_Id, NULLIF(@VarCourse_Id, 0))

AND ...

END
