You can also declare function to return 'setof record' type, but his has one disadvantage: when you do SELECT from this function, you have to write all fields and their types in the statement like this:<br />
<br />
SELECT * from my_function(argument) (int field1, text field2, timestamp filed3....) (just an example, look in the manual for syntax and usage info).<br />

Hello,<br />
<br />
I'm trying to create a new postgresql function (stored procedure) and I would like to know which return type I've to use in the following query :<br />
<br />
select *<br />
from table1 t1,table2 t2<br />
where t1.pid = t2.pid<br />
<br />
<br />
I cannot use the return type table1 because the query also returns table2-values.<br />
<br />
I've already tried this : RETURNS SETOF &quot;anyelement&quot;. But it doesn't work.<br />
<br />
<br />
<br />
Thanks ...<br />

return type of PostgreSQL function when joining 2 tables

PostgreSQL is an object-relational database management system with an emphasis on extensibility and standards-compliance. As a database server, its primary function is to store data securely, supporting best practices, and to allow for retrieval at the request of other software applications. PostgreSQL implements the majority of the SQL2011 standard, is ACID-compliant and transactional using multiversion concurrency control (MVCC), and handles complex SQL queries using many indexing methods that are not available in other databases. It is cross-platform and runs on many operating systems including Linux, FreeBSD, OS X, Solaris, and Microsoft Windows.
