New SQL utility posted.

I have posted a new utility to www.think400.dk/downloads.htm.

XVSETO (SetQueryOption) automates the process of setting a temporary
query option in file QAQQINI.

Normally to set a query option, you need to do the following steps.

1. Use CRTDUPOBJ to make a copy of QAQQINI into QTEMP.
2. Issue update to change query option to new value.
3. Issue CHGQRYA to point to copy in QTEMP.

All in all, a royal pain.

SetQueryOption automates this. For example, to set the default join
order, run the following in STRSQL.

CALL SETQUERYOPTION ('FORCE_JOIN_ORDER', '*YES')

To use in RPG program.

/Exec Sql CALL SETQUERYOPTION ('FORCE_JOIN_ORDER', '*YES');

or

/Exec Sql
+ CALL SETQUERYOPTION ('FORCE_JOIN_ORDER', '*YES')
/End-Exec

To reset the default,

CALL SETQUERYOPTION ('FORCE_JOIN_ORDER', '*DEFAULT')

Further information is in the readme packaged with the download.
