Member Enumeration Documentation

Options that affects what kind of query is built

Enumerator:

O_LOOKUP	Query should be a lookup
O_SCAN	Query should be a scan
O_PK_INDEX	Query might use primary key index
O_UNIQUE_INDEX	Query might use unique index
O_ORDERED_INDEX	Query might use ordered index
O_TABLE_SCAN	Query might table scan
O_RANDOM_OPTIONS	If not any options set, random query qill be created

Definition at line 33 of file HugoQueryBuilder.hpp.

const NdbQueryDef * HugoQueryBuilder::createQuery ( bool takeOwnership = false )

We only don't support table scans as child operations...

Iff root is lookup...ordered index scans are not allowed as children
