Re: Integers with embedded SQL problem

["Andrew Lutz" <alutz@xxxxxxxxxxxx>]

Bruce,

Time to update that certification.......

With SQL I can create a table on the AS/400 with a field SMLINT, this attribute 
CAN hold 32767 (notice the 5 digits).

With SQL I can create a table on the AS/400 with a field INT, this attribute 
CAN hold 2147483647 (notice the 10 digits)

On the AS/400 I can with:
RPGLE
SQL

Write, Update, Read  this field with a value of 32767

With embedded SQL
I CAN NOT


THIS IS THE ISSUE!

It let you do it because the DEC type is packed decimal. Then in the
program, you asked for 10 digits, integer or binary, you got them.

In the RPG program you declared 10i. But take a look at the cross reference.
This is what I ranted about not too long ago. It will probably show up in
the RPG cross reference as packed decimal. RPG does this to you.

Declaring the file in SQL as INT will present a binary 9 digit field.
Declaring SMALLINT will present a 4 digit field.

These are not pre-compiler issues, they are DDL issues. (Data Definition
Language, part of SQL.)

The result is as you did, if you really need 10 digits, the NUMERIC for
zoned, DEC for packed or live with 9 on INT.

For the case of the 5 digits, then you need INT for 9, NUMERIC for zoned,
DEC for packed, but SMALLINT won't hold it after the DDL materializes in the
physical file.
