ASF GitHub Bot updated CALCITE-3563:
------------------------------------
Labels: pull-request-available (was: )
> Convert function operand type to match implementation if necessary in runtime
> -----------------------------------------------------------------------------
>
> Key: CALCITE-3563
> URL: https://issues.apache.org/jira/browse/CALCITE-3563
> Project: Calcite
> Issue Type: Sub-task
> Components: core
> Reporter: Feng Zhu
> Assignee: Feng Zhu
> Priority: Major
> Labels: pull-request-available
>
> Sub-task targets on following issue.
>
> (1)Validation phase allows a wide range of operand types, but the runtime
> implementation does not cover all cases.
> For example, _*SqlFunction(MOD)*_ adopts
> _*OperandTypes.EXACT_NUMERIC_EXACT_NUMERIC*_.
> {code:java}
> @Test public void test0() {
> final String sql = "SELECT mod(12.5, cast(1 as bigint))";
> CalciteAssert.that()
> .query(sql)
> .returns("EXPR$0=0.5\n");
> }{code}
> We will get:
> {code:java}
> java.lang.RuntimeException: while resolving method 'mod[class
> java.math.BigDecimal, long]' in class class
> org.apache.calcite.runtime.SqlFunctions
> at org.apache.calcite.linq4j.tree.Types.lookupMethod(Types.java:323)
