Tips & Techniques - SQL

Many iSeries and AS/400 programmers still use the green-screen interactive SQL interface (STRSQL). One issue, however, with this SQL interface is that the F9 key did not behave like it did on other OS/400 5250 interfaces. The F9 key on most OS/400 5250 interfaces, such as the QCMD command line, provides a retrieve function that retrieves the source for all previously executed commands. STRSQL supported the F9 retrieve function, but it would retrieve only the last SQL statement--no matter how many times you pressed the F9 key. In contrast, if you pressed the F9 key two times on the QCMD interface, it would retrieve the second to last executed command; if the F9 key was pressed again, then the command source for the third to last command would be retrieved.

New PTFs now bring that same capability to cycle through all of the previously executed statements using the F9 key in an interactive SQL session. Instead of the F9 key retrieving only the last executed SQL statement, you can now cycle through all of the previously executed commands when using STRSQL. The PTF for V5R1 is SI08965; For V5R2, use SI08966.

In the STRSQL interface F9 will retrieve statements other than the most recent but you have to scroll to the statement and place the cursor on it before pressing F9. The QCMD interface works much the same way (except that it supports pressing F9 multiple times to retrieve the last command) The PTF to make the STRSQL F9 key behave as it does in the CMD interface is a welcome enhancement.
