The following are the new features in 4.46:

• The join execution performance has been improved, and you should see an overall decrease in execution times for SQL statements that include joins.



• The DBISAM Database Servers that are shipped with DBISAM now include the ability to use SQL performance tracking/logging to detect SQL statements that are exhibiting bad performance. This capability is a server-level feature, and is not implemented in the TDBISAMEngine component (it uses the SQL execution trigger in the engine). You can find out more information on the various dbsrvr.ini file options for the SQL performance tracking/logging here:
