Обсуждение: Create Function (SQL)

<tt>I am trying to create a simple function using SQL rather than PGSQL. At this point, it's just for the exercise.<br
/><br/> Is it possible to create a function similar to the following:<br /><br />     create function thing(text) as
select* from whatever where id=$1;<br /><br /> Do I need to specify all of the columns from the table (whatever) as out
parameters,or as a return type, or can I have a generic table returned from this?<br /><br /> Thanks,<br /><br />

You can return a record:

create function thing(text) returns record as 'select * from whatever
where id=$1' language sql;

Hope this helps.
