Dear Team, I have a table with name registers_info with below columns
regid character varying, transid bigint, regdate timestamp without time zone, canceldate timestamp without time zone insert into registers_info (regid,transid,regdate,canceldate) values ('reg1',1,to_timestamp('2013-07-24','yyyy-MM-dd hh24:mi:ss')::TIMESTAMP,to_timestamp('null','yyyy-MM-dd hh24:mi:ss')::TIMESTAMP); The above query works fine in Postgres 8.3 version. But the same query when executed in postgres 9.2 its throwing below error ERROR: invalid value "null" for "yyyy" Detail: Value must be an integer. >From application, this cancel date might have values or it may come as null. Kindly suggest. Thanks in advance. -- John
