Perl Restrictions
Some restrictions apply to the support that is available for application development in Perl.
The Perl DBI module supports only dynamic SQL. When you must execute a statement multiple times, you can improve the performance of your Perl applications by issuing a prepare call to prepare the statement.
For current information about the restrictions on a specific version of the DBD::DB2 driver installation, see the CAVEATS file in the DBD::Db2® driver package.
