Re: [GENERAL] data type serial
So how do you store something in data type serial? I've created the column but everytime I attempt to do an update I get back the error message that I can't store a duplicate key. table_col_seq.last_value = 1 increment = 1 maxvalue = 2billion something I've tried storing 1,2,some other number in "serial" in the main table to no avail. What is the magic to get this to work. There appears to be no documentation anywhere on the necessary SQL commands to cycle the generator. I've tried the method used for Oracle SQL but that does not work. I'm a bit of a newbie at this. Michael [EMAIL PROTECTED] You cant insert into a serial as far as I know. The serial is simply incrimented automatically whenever a new INSERT is done on the table. Hmmm that's a real problem when adding it to an existing table. The values I get back on a select indicate all blanks. I've got several hundred records in the table at the moment. There must be a way to update the darn things. Michael [EMAIL PROTECTED]

Re: [GENERAL] data type serial
If you have this table: create table testing ( id serial, datatext, md int ); You would use: insert into testing (data, md) values ('my_data', 12); insert into testing (data, md) values ('more data', 15); The key part is that you don't specify the serial field in your insert command. Anyway, hope this helps. At 09:45 PM 9/22/99, Michael wrote: So how do you store something in data type serial?

Michael [EMAIL PROTECTED] You could create a new table with the same attributes as the old, but with the serial in it, then insert into newone select from oldone... Then drop the old one and rename the new one That SHOULD do it (Ive not tried, I think it will tho) ~Michael
