Evgeny Stanilovsky updated CALCITE-6190:
----------------------------------------
Description:
Test highlights the problem :
{code:java}
@Test void testTypeOfAs() {
sql("select DECIMAL '100.01' as c1 from (values (true))")
.columnType("DECIMAL(5, 2) NOT NULL");
sql("select DECIMAL '-100.01' as c1 from (values (true))")
.columnType("DECIMAL(5, 2) NOT NULL");
}
{code}
Throws exception for second expression:
{noformat}
Expected: is "DECIMAL(5, 2) NOT NULL"
but: was "DECIMAL(6, 2) NOT NULL"
{noformat}
Seems root cause in SqlLiteral#createExactNumeric precision derivation not
consider negative numbers.
