[jira] [Created] (CALCITE-3331) Support implicit type cast for single operand family checker

Danny Chan created CALCITE-3331:
-----------------------------------

             Summary: Support implicit type cast for single operand family checker
                 Key: CALCITE-3331
                 URL: https://issues.apache.org/jira/browse/CALCITE-3331
             Project: Calcite
          Issue Type: Improvement
          Components: core
    Affects Versions: 1.20.0
            Reporter: Danny Chan
            Assignee: Danny Chan
             Fix For: 1.22.0


When the FamilyOperandTypeChecker is used to check single operand data type, support implicit type coercion if we can.

Now some of the sql operator override method #checkOperandTypes, and use the SqlSingleOperandTypeChecker#checkSingleOperandType to check the operand data type, we should support the implicit type coercion for these operators.
