Re: calling function

Hi Tom,

Well actually it worked via java now.

But I am really interested in what you said about first call.

I am creating the temp_accomm table everytime I call the function and drop
it in the end.

Let me explain the functionality. I need to get the result of a query which
joins 4 tables. The problem is because of this join I get more than one
record for one accomodation which is fine as there are multiple child images
for a accomm. What I have to do is concatenate the column of image table and
return in the resultset.

The out put looks like this

412|Hotel Cristallo|0|0|901#902|r82h06.jpg#r82h06.jpg|Hotel Cristallo#Hotel
Cristallo
413|Campo Smith Village|0|0|903#904|r83a06.jpg#r83a06.jpg|Campo Smith
Village and Great Western Hotel Rive#Campo Smith Village and Great Western
Hotel Rive

Do you still see any problem here.

One more thing in MS-SQL I used to create temp table using #. How can I do
that here in postgres?

Thanks
Bhushan

That function is only going to work once per session, because plpgsql
caches query plans. After the first call, the commands in the loop will
refer to a version of temp_accomm that doesn't exist anymore.

AFAICS you do not actually need the temp_accum table anyway. Why don't
you just return the data directly from the main loop?
