Nested Class Summary

private class

Rex2CalcPlanTest.TesterImpl.MyRelOptRuleCall

Constructor Summary

Rex2CalcPlanTest.TesterImpl(DiffRepository diffRepos)
Creates a TesterImpl.

Method Summary

private RelNode	callRule(RelOptRule rule, RelNode[] rels)
void	check(String sql, boolean nullSemantics, boolean shortCircuit) Compiles a SQL statement, and compares the generated calc program with the contents of a reference file with the same name as the current test.
void	checkAgg(String sql, boolean shortCircuit) Compiles a SQL statement containing aggregation, and compares the generated programs (init, add, drop) with the contents of a reference file.
void	checkWinAgg(String sql, boolean shortCircuit) Compiles a SQL statement containing windowed aggregation, and compares the generated programs (for init, add, drop and output) with the contents of a reference file.

Method Detail

check

public void check(String sql,
                  boolean nullSemantics,
                  boolean shortCircuit)

Description copied from interface: Rex2CalcPlanTest.Tester

Compiles a SQL statement, and compares the generated calc program with the contents of a reference file with the same name as the current test.

Specified by:

check in interface Rex2CalcPlanTest.Tester

Parameters:

sql - SQL statement. Must be of the form "SELECT ... FROM ... WHERE".

nullSemantics - If true, adds logic to ensure that a WHERE clause which evalutes to NULL will filter out rows (as if it had evaluated to FALSE).

shortCircuit - Generate short-circuit logic to optimize logical operations such as AND and OR conditions.

checkWinAgg

public void checkWinAgg(String sql,
                        boolean shortCircuit)

Description copied from interface: Rex2CalcPlanTest.Tester

Compiles a SQL statement containing windowed aggregation, and compares the generated programs (for init, add, drop and output) with the contents of a reference file.

Specified by:

checkWinAgg in interface Rex2CalcPlanTest.Tester

Parameters:

sql - SQL statement. Must be of the form "SELECT agg OVER window, agg OVER window ... FROM ... WINDOW decl".

shortCircuit - Generate short-circuit logic to optimize logical operations such as AND and OR conditions.

callRule

private RelNode callRule(RelOptRule rule,
                         RelNode[] rels)

checkAgg

public void checkAgg(String sql,
                     boolean shortCircuit)

Description copied from interface: Rex2CalcPlanTest.Tester

Compiles a SQL statement containing aggregation, and compares the generated programs (init, add, drop) with the contents of a reference file.

Specified by:

checkAgg in interface Rex2CalcPlanTest.Tester

Parameters:

sql - SQL statement. Must be of the form "SELECT ... FROM ... WHERE ... GROUP BY ...".

shortCircuit - Generate short-circuit logic to optimize logical operations such as AND and OR conditions.
