Easy column headings for query output files
When using Query/400 to output a file the column headings can become less than meaningful. Use this technique to update the column headings.
When using Query/400 to output a file the column headings can become less than meaningful. Use this technique to update the column headings -- it was done via SQL statements in QMQRY.
It's easy, here is the process:
Your query must output the file with an option 4 -- replace member (otherwise you would overlay the file's attributes each time). Enter source into a source file in your library -- I call mine QQMQRYSRC.
LABEL ON library/filename
(field1 is 'heading 1',
field2 is 'heading 2',
field3 is 'heading 3',
field4 is 'heading 4',
field4 is 'heading 4')
After you have saved your source you must compile using the following command:
CRTQMQRY QMQRY(yourlibrary/qmqryname)
SRCFILE(yourlibrary/QQMQRYSRC)
STRQMQRY yourlibrary/qmqryname The file should now have the new column headings and there should be no need to run the QMQRY again.
Do this for your own files only and not for any production files. If your file is created by query you must use the replace member option, which is option 4 of the output options.
