Mihai Budiu closed CALCITE-5901.
--------------------------------
Resolution: Not A Problem
> Compiler should not accept DECIMAL types with precision < scale
> ---------------------------------------------------------------
>
> Key: CALCITE-5901
> URL: https://issues.apache.org/jira/browse/CALCITE-5901
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.35.0
> Reporter: Mihai Budiu
> Priority: Minor
>
> The following test, when added to to SqlOperatorTest, passes:
> {code:java}
> f.checkScalar("cast(0.012 as DECIMAL(2, 5))", new BigDecimal("0.012"),
> "DECIMAL(2, 5) NOT NULL");
> {code}
> However, according to the SQL standard "The <scale> of an <exact numeric
> type> shall not be greater than the <precision> of the <exact numeric type>."
> In this case the precision is 2 and the scale is 5.
> So I would expect this test to fail. The validator should reject such types.
> I think that this change would affect quite a few tests.
