And we should remember that we provide a COMMON way to define databse structure. In others databases serial not awlays means primary key (rather auto increment)

IMO, RDBMS are too different to provide single common .sch "syntax&semantics" for all of them.

I think we should solve the problem of multi-field primary key.
Does it work in upp?:

In Oracle, yes:

Quote:

TABLE_(O_POLOZKA)
INT_ (O_POLOZKA_SEQ) INDEX
INT (O_DOKLAD_SEQ) REFERENCES(O_DOKLAD) INDEX
STRING (POPIS, 2000)
DOUBLE_ (CENAJ)
INT_ (MNC)
INT_ (MNJ)
DUAL_PRIMARY_KEY(O_POLOZKA_SEQ, O_DOKLAD_SEQ)
END_TABLE

Obviously, not as sexy as simply puttin more "PRIMARY_KEY" columns, OTOH at least Oracle SQL syntax is similar - you have to add it in single contraint, not as several "PRIMARY_KEY" comlums.
