I have a variable @Var1 varchar(100) and then a second variable @var2 varchar(10); How can I use either PatIndex or CharIndex to check if @Var1 starts with @Var2 or @Var1 ends with @Var2?

Your answer is well appreciated.

You can use this approach for example:

SQL

declare @val1 varchar(100)
set @val1='abcd'

declare @val2 varchar(10)
set @val2='ab'

if @val1 LIKE @val2 + '%' print 'STARTSWITH'
if @val1 LIKE '%' + @val2 print 'ENDSWITH'

Interestingly, I have the same logic exactly already, but it's not working. The thing is , I am pulling both variables from two diffent tables; it may not be my logic but the data types.

Thank you; like I commented above; this logic is ok; my problem was related to something different.

Than post your exact situation here. This is the answer to what you requested. If it is not working, than your question is not covering your needs.

The problem was because that part of the code was not running at all because a condition above this logic was not being met. I fixed that and it worked as I expected. Thanks man.
