PERFORM statement question

From
"Keith Worthington"
Date:
Hi All,

Well, I am continueing to make progress on my function to transfer or update
data as required.  However I have hit another snag.  After I successfully
create the function below I atttempt to run it with the command

SELECT xfer_gl_account_data();

And get the error

WARNING:  Error occurred while executing PL/pgSQL function xfer_gl_account_data
WARNING:  line 11 at assignment
ERROR:  parser: parse error at or near "SELECT" at character 9

This was an error regarding not using a PERFORM statement but now the PERFORM
is in there and it still won't work.  I have read
http://www.postgresql.org/docs/7.3/interactive/plpgsql-statements.html#PLPGSQL-STATEMENTS-PERFORM
to no avail.

Obviously I am not using the PERFORM command peroperly but I do not
understand.  Hints greatly appreciated.

Kind Regards,
Keith

You just want "PERFORM peachtree...", that is, the PERFORM keyword
is syntactically a substitute for SELECT.  The manual is not very
good about this :-( ... I've tried to make it clearer in the 8.0
docs.

Replying to myself:

Woohoo!

On a whim I changed PERFORM SELECT... to PERFORM and... something else broke.
 As I am sure the experienced programmers are saying "Well of course you items
are over specified."  Yeah, yeah.  We all have to learn. :-)  Fixed that and
wham, it worked.

Now I need to add a couple more conditionals and I will almost be there.
