Multi-Platform Tuning Interface
Automate SQL tuning across all major DBMSs (Oracle, SQL Server, DB2 and Sybase) from a single common interface, and use the tool on all supported platforms from a single license. Streamline and automate common and repetitive tasks with an easy-to use GUI and powerful wizards.
Create and run tuning jobs for a single statement or batch of statements. Tune all DML statements, stored routines and entire SQL files.
SQL Rewrites & Case Generation
SQL rewrites are suggested as part of the case generation in the SQL tuner as well as when you type in the SQL IDE. SQL rewrites and hint injection are used to generate all possible cases and find the best alternative to a given SQL statement.
Customise the subset of hints to be considered for hint injection and alternative execution paths.
Explain Plan Cost
View the explain plan cost for each original statement and each generated case to give the user the expected cost given the execution path utilised by the database.
Visual SQL Tuning
The Visual SQL Tuning (VST) diagram displays indexes and constraints on tables and views as well as the joins used in a SQL statement such as Cartesian joins, implied Cartesian joins and many-to-many relationships, with table statistics.
The color-coded Index Analysis feature shows indexes that are used (green), not used (blue) or missing (orange) and offers indexing recommendations for optimum performance.
Run the SQL with alternative execution paths to discover the fastest running SQL statement, and apply the change at the click of a button.
Textual Comparison of Cases
A visual difference viewer helps the user spot the textual differences between any two SQL statements.
