Hello,
I have a question about "date" & "timestamp" types in PostgreSQL. I want to setup the default value '0000-00-00' and "0000-00-00 00:00:00" for them. However, it seems that PostgreSQL does not support it. Could someone helps me please?
The example table:
T1 (col1 varchar(7) not null, col2 varchar(4) not null, col3 date not null, col 4 varchar(3), primary key(col1, col2, col3) )
In my design model, "col3" has to be one of the primary key part. Since at the beginning of the data population, we do not know the value of "col3"; values for "col3" are input throught GUI. Therefore, when I use MySQL, the default values I gave is "0000-00-00". However, after I migrate to postgreSQL, I could not setup the default values as "0000-00-00" any more. Could somebody help me about it please? I'd like to know how I can save '0000-00-00' as the default value for "date" and "timestamp" types.
By the way, I also tried "my2pg.pl" to migrate table structures got by mysqldump to postgreSQL. The places I have '000-00-00' have been changed to '0001-01-01' by this perl script.
Thanks a lot in advance, Emi Lu
