Re: Why I cannot call a function from within an SQL function? - Mailing list pgsql-general

Hi Ho!

The following query works well:

 select count (*)
 from item_audit
 where audit_ts >= '2008-05-30 00:00:00'
      and audit_ts <= '2008-10-30 00:00:00'
      and 'wst' != (select split_part(category, '-', 2)
                    from description
                    where split_part(category, '-', 1) = 'item'
                          and shorthand = status
                   )

But, when I transform it into the following SQL function, the function cannot be created barking:

 ERROR:  syntax error at or near "-"
 LINE 6:        and $1 != (select split_part(category 2)"

 create or replace function get_I(text, timestamp, timestamp) returns bigint as
'select count (*)
 from item_audit as ia
 where audit_ts >= $2
      and audit_ts <= $3
      and $1 != (select split_part(category, '-', 2)
                 from description
                 where split_part(category, '-', 1) = 'item'
                       and shorthand = ia.status
                )
' language sql;

What's wrong?

Thank you.
