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???
