Обсуждение: 'current' timestamp bug
It seems some input validation isn't working somewhere. Unless I'm missing something and somehow 'current' is a magic timestamp value (in which case the jdbc driver should be able to parse it somehow). playpen=# update tablea set ts = current_timestamp where id = 1; UPDATE 1 playpen=# select * from tablea; id | ts ----+------------------------ 1 | 2001-05-07 16:32:55-04 (1 row) playpen=# update tablea set ts = 'current_timestamp' where id = 1; UPDATE 1 playpen=# select * from tablea; id | ts ----+--------- 1 | current (1 row) playpen=# update tablea set ts = 'foo' where id = 1; ERROR: Bad timestamp external representation 'foo' playpen=# update tablea set ts = 'current_foo' where id = 1; UPDATE 1 playpen=# select * from tablea; id | ts ----+--------- 1 | current (1 row) playpen=# update tablea set ts = 'xxxxxxxfoo' where id = 1; ERROR: Bad timestamp external representation 'xxxxxxxfoo' -- Joseph Shraibman jks@selectacast.net Increase signal to noise ratio. http://www.targabot.com

Probably. 'current' is just weird and will be removed in 7.2. -- Peter Eisentraut peter_e@gmx.net http://funkturm.homeip.net/~peter
