Is aggregate, index, etc
std::string Vertica::ServerInterface::RelationDescription::additionalDerivationInfo |
Further description of derivation
std::vector<int> Vertica::ServerInterface::RelationDescription::baseAttrIdx |
Columns in base that participate in derivation
Oid Vertica::ServerInterface::RelationDescription::baseRelation |
Derivation from a base object (table/projection)
std::vector<std::string> Vertica::ServerInterface::RelationDescription::colNames |
Column names
std::vector<bool> Vertica::ServerInterface::RelationDescription::colRLE |
For projections, indictor if encoding is run-optimized
std::vector<VerticaType> Vertica::ServerInterface::RelationDescription::colTypes |
Column types
std::string Vertica::ServerInterface::RelationDescription::databaseName |
Database name
std::vector<Oid> Vertica::ServerInterface::RelationDescription::derivationFunctions |
Derivation function, for UDT proj, etc.
bool Vertica::ServerInterface::RelationDescription::isExternal |
Is for external table?
bool Vertica::ServerInterface::RelationDescription::isFlex |
Is this a flex object
bool Vertica::ServerInterface::RelationDescription::isSystem |
Is this a system object
bool Vertica::ServerInterface::RelationDescription::isTemp |
Is for a temp table?
bool Vertica::ServerInterface::RelationDescription::isUpToDate |
Is this up to date / active
int Vertica::ServerInterface::RelationDescription::nSortedCols |
For projections, number of columns in sort order, as a prefix
std::vector<int> Vertica::ServerInterface::RelationDescription::partitionCols |
For tables / projections, columns involved in partitioning
std::vector<int> Vertica::ServerInterface::RelationDescription::pkCols |
For tables / projections, columns involved in a primary key
std::set<std::string> Vertica::ServerInterface::RelationDescription::presentOnNodeNames |
For projections, hosting node names
std::set<Oid> Vertica::ServerInterface::RelationDescription::presentOnNodes |
For projections, hosting nodes
std::string Vertica::ServerInterface::RelationDescription::relationName |
Table name, projection basename, or projection name
Oid Vertica::ServerInterface::RelationDescription::relationOid |
Relation OID, for lookups if this is nonzero it takes precedence
std::string Vertica::ServerInterface::RelationDescription::schemaName |
Schema name; on lookup if empty the search path will be consulted
std::vector<int> Vertica::ServerInterface::RelationDescription::segCols |
For projections, columns involved in segmentation
int Vertica::ServerInterface::RelationDescription::segOffset |
For buddies, segmentation offset
std::vector<int> Vertica::ServerInterface::RelationDescription::tabColMapping |
For projections, mapping to table column number (0-based); negative numbers would indicate things that are not present in the table
