Ruben Q L commented on CALCITE-6265:
------------------------------------
I just found a simple test (to be added to JdbcTest.java) related to my case A,
that would have worked fine before this commit, and now it's broken:
{code}
@Test void bindDecimalParameter() {
final String sql =
"with cte as (select 2500.55 as val)"
+ "select * from cte where val = ?";
CalciteAssert.hr()
.query(sql)
.consumesPreparedStatement(p -> {
p.setBigDecimal(1, new BigDecimal("2500.55"));
})
.returnsUnordered("VAL=2500.55");
}
{code}
I'll try to provide a PR with a fix...
