Method Detail

testWhenNonBoolean

public void testWhenNonBoolean()

Test various statements that

testAllDatatypesCombinationsForCaseExpressions

public void testAllDatatypesCombinationsForCaseExpressions()
                                                    throws java.sql.SQLException

Throws:

java.sql.SQLException

testMultipleWhens

public void testMultipleWhens()
                       throws java.sql.SQLException

Test a query that has many WHEN conditions in it. This is mostly checking for the performance regression filed as DERBY-2986. That regression may not be noticeable in the scope of the full regression suite, but if this test is run standalone then this fixture could still be useful.

Throws:

java.sql.SQLException

suite

public static junit.framework.Test suite()

Runs the test fixtures in embedded.

Returns:

test suite

testCaseExpressionQuery

private void testCaseExpressionQuery(java.sql.Statement st,
                                     java.lang.String[][] expRS,
                                     java.lang.String caseExprBegin,
                                     java.lang.String caseExprEnd)
                              throws java.sql.SQLException

Execute the received caseExpression on the received Statement and check the results against the receieved expected array.

Throws:

java.sql.SQLException

testDerby3032

public void testDerby3032()
                   throws java.sql.SQLException

Test fix for DERBY-3032. Fix ClassCastException if SQL NULL is returned from conditional.

Throws:

java.sql.SQLException
