Hi,

2014-10-05 6:23 GMT+02:00 Hector Menchaca <hm34306(at)hotmail(dot)com>:

All,Struggling tying to get a function that works in Maraidb stored procs...looking to return an OUT Parameter value with Return Query
CREATE FUNCTION sp_AgentServer_Register (_agentserver_name TEXT, _port INTEGER, out _out_agent_server_id INTEGER) RETURNS SETOF AgentServerAS $$BEGIN Select _agent_server_id INTO _out_agent_server_id FROM sp_private_AgentServer_Insert(_agentserver_name, _port);
Update AgentServer SET RegisteredOn = NOW() where AgentServer_ID = _out_agent_server_id;
RETURN QUERY Select * From AgentServer where AgentServer_ID = _out_agent_server_id; END$$ LANGUAGE plpgsql;
In doing this an error is returned :ERROR: function result type must be integer because of OUT parameters
If I change to Integer, then I get an Error From the return query...ERROR: cannot use RETURN QUERY in a non-SETOF function
Is there a way to do this? (I'm assuming no at this point... i hoping there is some flag or something that I can set...)I can do this with MariaDB and SqlServer...

In the above function, you don't need the ", out _out_agent_server_id INTEGER" because you already have it in the AgentServer record it sends back. So get rid of it, and it should work.
