Is there an alternative for LIKE that returns all the records when the given value is an empty string? Thanks.

No. That you have to handle somewhere. Like takes something and returns result similar to that one. You have to check some condition that if the passed parameter is blank get all the results.

I have 3 where condition in my query. I'm thinking of doing this:

WHERE (@parameter IS NULL OR NAME = @parameter) AND . . . .

Would this be acceptable? Do I need to enclose it in parenthesis?

I guess you should better use it like
where ...... AND (name='' OR name=@parameter); and this should work.

I don't think so Tim! (famous words by the neighbour of Tim the Toolman;) )
When you do not pass the parameter it is NULL.

Hi,

Try this...

SQL

Select * from yourTable where name = case when isnull(@para,'') ='' Then name else @para end

Hope this will help you.

Cheers

You don't need the LIKE operator: you may directly use the = operator, e.g.

SQL

select * from mytable where name=''
