  Column1 has a code and in column2, it's the description of the code. See attached file.

  I am joining this table with one more table by the code (column1) and pulling the description from column2. There are multiple entries of the same code and description. So I did the DISTINCT statement and came across one more problem.

  Here's the problem, there are multiple entries of Column2 which includes just extra '-I/P'or '-O/P', but have the same code (column1). If I do a join like this, I think SQL will freak out. I could delete rows with '-I/P'or '-O/P', but sometimes there is one entry which has either '-I/P'or '-O/P'.

  So here's what I am trying to do. First do a distinct statement. Then, I wanna check if code (column1) value\ exist more than one, and if they do, then delete the row which has '-I/P'or '-O/P' in column2.

  Any ideas?
