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
getTable().
Note
This method was added in MySQL 5.1.12. (See Bug#21690.)
Signature.
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.
