Re: Question on Delete in Embedded SQL

[rob@xxxxxxxxx]

Lori,

This can be done, and in ONE sql statement, providing we have some common
facts.  If one file is a parent of the other.  For example, if you have an
item file and an item activity file.  Let's say the key to ITEM is ITEM#
and the key to ITEMACT is ITEM# and UUID.  What you do is:
1)  Create a journal and start journalling on both files.
2)  Use Operations Navigator or some green command to set up referential
integrity between the two files.  When you set this up, tell it to CASCADE
upon delete.

Then when you delete the item# from ITEM it will delete any children from
ITEMACT.

Basically, in a good database design, steps 1 and 2 are already done,
right?

Hello,

I have a question on delete in an embedded SQL.  Could anyone help me out.
Does anyone have an example of a working delete using SQL?  I am trying to
delete records out of two files with the same key.  My attempt is below.

Thanks in advance for any help
Lori Crane
