Method Detail

testDefinedSchema

public void testDefinedSchema()

If a schema is defined, then the planner has combined the projection list with schema information to produce the final output schema at plan time.

testDynamicDefinedSchema

public void testDynamicDefinedSchema()

If a schema is defined, then the planner has combined the projection list with schema information to produce the final output schema at plan time. The planner might leave some columns as dynamic type: the schema (like projection) says which columns are wanted. But, like a full dynamic schema, the types may not be known.

testTooShortProjection

public void testTooShortProjection()

It is an error if the provided schema does not match the projection list. (Actually, the projection list is redundant in this case. But, since Drill does not actually support a defined schema yet, we have to be a bit vague.

testTooLongProjection

public void testTooLongProjection()

testDisjointProjection

public void testDisjointProjection()

testDefinedSchemaWildcard

public void testDefinedSchemaWildcard()

testEmptyProjectWithDefinedSchema

public void testEmptyProjectWithDefinedSchema()
