Re: SQL foreign key question

Hi Loyd,

These statements run fine for me in Run SQL Scripts in iSeries Navigator at
V5R3.

Which release of the OS are you on?

How are you running the statements (i.e. what do you mean by "compile")?

You do have a GUI available for defining tables, indexes, views,
constraints, triggers, aliases etc. etc. in iSeries Navigator - so you can
get back to spoiling yourself :-)

HTH
