----------------------------------------
TestMergeStatement.testNegative5:
{code}
/**
* why does this fail but next one passes
* @throws ParseException
*/
@Test
public void testNegative5() throws ParseException {
expectedException.expect(ParseException.class);
expectedException.expectMessage("line 1:103 mismatched input '+' expecting
) near 'b' in value row constructor");
//todo: why does this fail but next one passes?
ASTNode ast = parse(
"MERGE INTO target USING source ON target.pk = source.pk WHEN NOT MATCHED
THEN INSERT VALUES(a,source.b + 1)");
}
{code}
will remove it as we will support it.
> Support expression in merge statement
