Re: Delete Duplicate Rows

Michael, you can do this neatly with a QMQRY, if you are talking about the 
entire row being duplicated. Go to STRQM, then option 1 for QMQRY. Create a new 
one called CUTDUPES, say, and put

SELECT DISTINCT * FROM YOURLIB/YOURFILE

as the statement. This eliminates the duplicates.

Now at a command line use

STRQMQRY CUTDUPES OUTPUT(*OUTFILE)
OUTFILE(YOURLIB/YOURFILE)
OUTMBR(*FIRST *REPLACE)

You are telling it to create a record set that consists only of the distinct 
records, then take that record set and save it back to the same place it came 
from. It will replace the contents of the file with the output of the SELECT 
statement. STRSQL will not allow this - it blocks using the same file for 
output as the one named in the SELECT (F13 is where I tried to set this up).

The STRQMQRY technique is definitely dangerous and not for the faint of heart - 
but very handy when needed.
