Hello,
I would know if it's possible to use the EXECUTE Command in PSQL as SQL
command in Pg 7.2 release.
In fact, this can make possible the dynamic query execution by using PSQL. I
tried to use PGPLSQL function that returns RECORD type without success. For
example when I create the following function :
Create function Foo (TEXT) returns RECORD As'
declare
query alias for $1;
begin
return (execute query); -- query is a sql select command (in general it's
created dynamiquelly).
end;
' language 'plpgsql';
I receive this message
NOTICE: ProcedureCreate: return type 'record' is only a shell.
the execution of this function prompts the following error:
ERROR: fmgr_info: function 0: cache lookup failed.
I think that de record type is created to contain table tuples regardless of
their structure. Is-this right? So, why we can't use it to contain any query
result?
Thanks for your help.
Mourad.
