Hi,

I am in urgent need for converting sql procedure to postgre sql procedure.Please help me ASAP.

CREATE FUNCTION sp_get_id_des (IN cellid INT, IN mcc VARCHAR(3), IN mnc VARCHAR(3), IN nwtype INT, IN mlac INT , IN mrac INT ) returns SETOF record AS'

 declare cscnt int;

 declare pscnpoolid varchar(20);

assert "Create sp_get_id_des"

Please help me in converting above procedure into postgre
Please suggest alternative in postgresql for the given sql statement DECLARE CONTINUE HANDLER FOR SQLSTATE '42S02' SET @x2 = 1;, GROUP_CONCAT,temporary table.

Thanks and regards
