Method Detail

getTableForMember

public RelOptTable getTableForMember(String[] names)

Description copied from interface: RelOptSchema

Retrieves a RelOptTable based upon a member access.

For example, the Saffron expression salesSchema.emps would be resolved using a call to salesSchema.getTableForMember(new String[]{"emps" }).

Note that name.length is only greater than 1 for queries originating from JDBC.

Specified by:

getTableForMember in interface RelOptSchema

getTableForMember

public RelOptTable getTableForMember(String[] names,
                                     String datasetName,
                                     boolean[] usedDataset)

Description copied from interface: RelOptSchemaWithSampling

Retrieves a RelOptTable based upon a member access, using a sample dataset if it exists.

Specified by:

getTableForMember in interface RelOptSchemaWithSampling

Parameters:

names - Compound name of table

datasetName - Name of sample dataset to substitute, if it exists; null to not look for a sample

usedDataset - Output parameter which is set to true if a sample dataset is found; may be null

Returns:

Table, or null if not found

createColumnSet

protected SqlToRelTestBase.MockRelOptSchema.MockColumnSet createColumnSet(SqlValidatorTable table,
                                                                          String[] names,

                                                                          List<RelCollation> collationList)

getTypeFactory

public RelDataTypeFactory getTypeFactory()

Description copied from interface: RelOptSchema

Returns the type factory used to generate types for this schema.

Specified by:

getTypeFactory in interface RelOptSchema

registerRules

public void registerRules(RelOptPlanner planner)
                   throws Exception

Description copied from interface: RelOptSchema

Registers all of the rules supported by this schema. Only called by RelOptPlanner.registerSchema(org.eigenbase.relopt.RelOptSchema).

Specified by:

Throws:

Exception
