columnHasDefaultValue

public boolean columnHasDefaultValue(RelDataType rowType,
                                     int ordinal,
                                     InitializerContext initializerContext)

Description copied from interface: SqlValidatorTable

Returns whether the ordinal column has a default value.

Specified by:

columnHasDefaultValue in interface SqlValidatorTable

extend

public final RelOptTable extend(List<RelDataTypeField> extendedFields)

Description copied from interface: RelOptTable

Returns a table with the given extra fields.

The extended table includes the fields of this base table plus the extended fields that do not have the same name as a field in the base table.

Specified by:

extend in interface RelOptTable

extend

protected abstract RelOptTable extend(Table extendedTable)

getColumnStrategies

public List<ColumnStrategy> getColumnStrategies()

Description copied from interface: RelOptTable

Returns a list describing how each column is populated. The list has the same number of entries as there are fields, and is immutable.

Specified by:
