Description.  This method computes aggregate data for the table. It is required in order for aggregate methods such as getNoOfPrimaryKeys() to work properly before the table has been created and retrieved via getTableId().


This method was added in MySQL 5.1.12 (see Bug #21690).


int aggregate
      struct NdbError& error

Parameters.  A reference to an NdbError object.

Return value.  An integer, whose value is 0 on success, and -1 if the table is in an inconsistent state. In the latter case, the error is also set.
