Interface Rex2CalcPlanTest.Tester

All Superinterfaces:

SqlToRelTestBase.Tester

All Known Implementing Classes:

Rex2CalcPlanTest.TesterImpl

Enclosing class:

Rex2CalcPlanTest

static interface Rex2CalcPlanTest.Tester
extends SqlToRelTestBase.Tester

Test helper. The default implementation is Rex2CalcPlanTest.TesterImpl, but sub-tests can customize behavior by creating their own Tester.

Method Summary

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

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.

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

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.

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.

checkAgg

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.

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.
