Features comparison
Both Oracle 9i Database and IBM DB2 Universal Database v8.1 support the ANSI
SQL-92 entry level and do not support the ANSI SQL-92 intermediate level. In the
Features comparison section of this article I want to make the brief comparison of
the PL/SQL with DB2 SQL dialect and show some Oracle 9i Database and DB2
Universal Database v8.1 limits.
PL/SQL vs DB2 SQL dialect
The dialect of SQL supported by Oracle 9i Database is called PL/SQL. The dialect of
SQL supported by IBM DB2 v8.1 is called DB2 SQL dialect. This is the brief
comparison of PL/SQL and DB2 SQL dialect:

Conclusion
It is not true that Oracle 9i Database is better than DB2 Universal Database v8.1 or
vice versa. Both products can be used to build stable and efficient system and the
stability and effectiveness of your applications and databases depend rather from the
experience of the database developers and database administrator than from the
database's provider.
