You may check the existence of a table or view against the SysTables-View
located in the QSYS2 schema.:

Select 1 into :Exists
From SysTables
Where Table_Name = :YourTableName and Table_Schema =:YourTableSchema

The SQL statement above checks for the long names. If you prefer the
short/system names, those can be found in the System_Table_Name and
System_Table_Schema columns.

Betreff: SQL Check If File Exists (via RPG)

I have a situation where I need to update/add/delete records in a historical
snapshot file (or files) if the current live file is changed (retro-active
changes). 

The historical files are named by year/month and may or may not exist for
a selected record.

Looking for suggestions on the quickest easiest way to verify a file's
existence.  This will be in a trigger program.

Thanks.
