Hello,
I have a select query which uses Trim function..like

Select * from Tbl1 where ltrim(name) = @name.

I am using this trim functions very often, the perfomance is hitting low....

It would be of great help.

Trim the data when you insert it into the database.

The following will allow index scans:

SELECT *
FROM Tbl1
WHERE [name] LIKE '%' + @name

but will allow characters other than space at the beginning.
