Member Data Documentation

const int* NdbRecord::m_attrId_indexes

Array mapping an attribute Id into the corresponding index into the columns[] array, useful for looking up a column by attribute id.

If the column is not included in the NdbRecord, the value is -1.

Definition at line 232 of file NdbRecord.hpp.

Uint32 NdbRecord::m_no_of_distribution_keys

Number of distribution keys (usually == number of primary keys).

For an index NdbRecord, this is zero if the index does not include all of the distribution keys in the table.
