Hi Rob

I don't use 1 = 1 in SELECTs but I do if I want to delete all records from a table - sometimes CLRPFM is not allowed - we have that in some circumstances on our systems - and a bare-naked DELETE FROM uses CLRPFM on IBM i. The WHERE 1 = 1 does not use CLRPFM. And I don't know the history for suppressing CLRPFM here.

Cheers
Vern

I fail to understand why all the WHERE conditions.
1=1??? Is this just a thing you always do to avoid warning errors that you have no where clause?

And why
... and substr(table_Schema,1,1) not in ('Q', '#')
When you have
and table_schema = 'DPPDATA'
D already excludes Q and #.
Let me guess your evolution.
First, I was right on the evolution on the 1=1, right?
Second, you started by specifying Q and # to only get "user" libraries?
Third, then you added just the library you wanted?
