Analyze Table Release For Free

When you analyze a table, both table and column statistics are collected. Both computed and estimated statistics are used by the Oracle Database optimizer to choose the execution plan for SQL statements that access analyzed objects.

Analyzing can be performed on the whole database or on specific table. The database or table does not get locked during this operation and your queries will perform better after this operation.

Simply select a cell in a data range > select the Analyze Data button on the Home tab. Analyze Data in Excel will analyze your data, and return interesting visuals about it in a task pane.
