Feng Zhu updated CALCITE-3565:
------------------------------
Component/s: core
> Explicitly cast assignable operand types to decimal for udf
> -----------------------------------------------------------
>
> Key: CALCITE-3565
> URL: https://issues.apache.org/jira/browse/CALCITE-3565
> Project: Calcite
> Issue Type: Sub-task
> Components: core
> Reporter: Feng Zhu
> Assignee: Feng Zhu
> Priority: Major
> Labels: pull-request-available
> Time Spent: 10m
> Remaining Estimate: 0h
>
> Type is assignable conceptually, but in the runtime phase, explicite cast is
> still required.
> For example, according to _*SqlTypeAssignmentRules*_,
> *_ST_MakePoint(Decimal, Decimal)_* also accepts operands with (_Integer_,
> _Decimal_) types, because Decimal is assignable from Integer.
> {code:java}
> @Test public void test1() {
> final String sql = "SELECT ST_MakePoint(1, 2.1)";
> CalciteAssert.that()
> .with(CalciteAssert.Config.GEO)
> .query(sql)
> .returns("EXPR$0={\"x\":1,\"y\":2.1}\n");
> }
> {code}
> We will get:
> {code:java}
> org.codehaus.commons.compiler.CompileException: Line 22, Column 124: No
