how you solve the problem with multilevel autoicrement? In MySQL you create table with col1, col2. Col 2 is AUTOICREMENT and you have to create UNIQUE INDEX (Col1, Col2). If you insert to this table for col1 volume 1, col2 automaticaly increase by one. Example: Insert into table values (1); Insert into table values (1); Insert into table values (2); Insert into table values (1); Insert into table values (2); Result is: 1,1 1,2 2,1 1,3 2,2 How you convert this functionality from MySQL to PgSQL??? -------------------------------------- Bruce Momjian wrote: >Michael Chaney wrote: > > >>One other note, for those converting a database from MySQL to >>PostgreSQL, I have a table creation conversion script here: >> >>http://www.michaelchaney.com/downloads/m2p.pl >> >>I know that two come with PostgreSQL in the contrib directory, but I >>wrote this because those two didn't do what I needed.
