Sv: Return Unique Id

Hi Das

I now use Postgres instead of SQLite.
As I see it now there are 2 ways of inserting a record:
1. The statement-method where you compose a sql-string and executes it with $execdirect.
2. The session-method where you let the table/schema perform an $insert based on a list.
I am now exploring the second one.
There are some values that I have typed into variables like iRow.user_id and iRow.user_name.
Then I do a Do iRow.$insert() Returns #F.
This inserts the record. Just one line of code for inserting.

Can I use the RETURNING clause in this second way of performing an insert?

If you are using Postgres or other powerful SQL database the clause you want is "RETURNING"

At the end of your select statement add RETURNING myColumn to the statement.

Then do a fetch into any undefined row or list and it will put the value as the first column in it, then you can grab it and add it into the row you are proceeding with.

You’re right, this is very important and necessary to intelligently continue with what follows your INSERT command.

If you are on SQLite there is another way of doing it that Omnis provides as a special SQLite command. I forget what it is, how it’s worded, but I can look it up if you need that. It’s something like

Do $statementObject.$lastrowid Returns theValue

With the SQLite DAM you can see $lastrowid as one of the commands offered. It gives you the PK of the last row inserted.
