Re: what does this do - Mailing list pgsql-sql

First remove the python
select * from jfcs_balancedue(parameter) f(enrolleeid varchar,course_cost decimal, paid_amt decimal)

the jfcs_balancedue is a table function,  f is the alias (with the column alias list/datatype of the columns returned
bythe function).

Hi,
I have a piece of python code that excutes a SQL statement:

apitempCur.execute("select * from jfcs_balancedue('%s') f(enrolleeid varchar,
course_cost decimal, paid_amt decimal)" % (enrollIds,));

The "enrollids" is a list of primary keys and the "jfcs_balancedue" is a user
defined function.  What I don't understand is the "f(enrolleeid
varchar, ...)"   I have no idea what it's for?  Would some kind soul educate
me.

Thanks in advance,
Jhnf
