Question

What is the regular expression pattern that enables every input besides characters? So far this is what i have –

CREATE PROCEDURE Paging_Movies
@alphaChar char(1)
AS
if @alphaChar = '#'
select * from Movies where movies like '[0-9]%'
else
select * from Movies where movies like @alphaChar + '%'

If you want true regular expression pattern matching you will need to roll your own CLR UDF. This link goes over how to do that:

Keep in mind that you can only do this in SQL Server 2005 or higher.

If you just want non-alpha you can do this:

'([^a-z])'

Here is the documentation for SQL Server like:
