Example: Index Analysis and Repeated Parameters - Teradata Database - Teradata Vantage NewSQL Engine

If index analysis parameters are specified, they must not be repeated. If the parameters are repeated, an error is reported.

In the following example, the only index analysis parameter specified, IndexesPerTable, is specified once.

     INITIATE INDEX ANALYSIS ON table_1
     FOR MyWorkload
     IN MyQCD
     AS table_1Index
     SET IndexesPerTable = 2;

In the following example, the index analysis parameter IndexesPerTable is specified twice, so an error is returned.

     INITIATE INDEX ANALYSIS ON table_1
     FOR MyWorkload
     IN MyQCD
     AS table_1Index
     SET IndexesPerTable=2, ChangeRate=4, IndexesPerTable=4;

     *** Failure 3706 Syntax error: Multiple "IndexesPerTable" options.

Note that the error is not caused by the discrepancy between the specified boundary conditions for the IndexesPerTable parameter: the same error would be reported if the boundary conditions matched in both specifications.
