then query refer the index, and i can see a result

I feel your pain;^)
Here is the text of a post from Tuesday... I think it answers your question
which is that you cannot do variable subsititution for table or field names
inside procedures. This is not a Postgres specific limitation, MS SQL
Server has the same issue.

not sure if that is the issue here or

Those two fields should have a data type. Same in your other examples.
cmdb(# date_rec timestamp default 'now',
cmdb(# units int4 default 0,
cmdb(# media_type
Your missing your fields types, i.e.:
CREATE TABLE media_received (
comp_id SERIAL NOT NULL,
dept_id INT4NOT NULL,
date_recTIMESTAMP DEFAULT 'now',
that should fix your problem...

Tom,
(and keep in mind
that Postgres functions currently have trouble with NULLS as
input parameters).
Not in 7.1 they don't ...
Really? Terrific. Sadly, I have 25+ PL/pgSQL functions not set up to
accept NULLs ...
Can you point me to (or tell me where to search) the developer notes
the select query returns the first row to rec. You can then access its values with:
rec.field_name
at END LOOP it jumps back to FOR checks to see if there any more rows and if so moves
to the next row and repeats the loop.
It also looks like your missing a LOOP keyword at the end of the FOR
Are ORDER BYs allowed in SQL functions? Or do SQL functions work like
views that are as unordered as their underlting tables?

works. But if I try

Tcl is my bread and butter but, coincidentally, I have just started considering
pl/tcl 2 days ago as the choice for server side pg programming. I do it in
microsoft t-sql right now, and plsql is pretty close to that. However, tcl is
like English to me, so I think I will go that way unless

Even a PL/PgSQL FAQ would be good.
