Question

I would like to build one sql query in that one of my filed of form should not contain common names (maintained list of words in separate table) and i am passing value of that filed as parameter and want to check that it shouldn’t contain any common name from that table.

How can i achieve that using sql query?

Note : if common name is ‘abc’ and i am passing parameter as ‘!abc123’ since it contains that word query should return false.

Thanks in advance.

Try this:

   IF NOT EXISTS(SELECT word FROM CommonWord WHERE @yourparam 
                 LIKE '%' + word + '%')
    BEGIN
       RETURN 1
    END
    ELSE
    BEGIN
      Return 0
    END

This works if the @yourParam is contained in any word or name, what you do not want to use. It only returns 1 if it is not contained by any row in the table.

I worte this sentence only on this way (you can use a simple Exists instead of NOT Exists), because may you want to extend the functionality in the true part.
