all other functions names are hardcoded and we just match the string literal in the code.

Hold the SQLConf will lead to unable to obtain real-time changes to SQLConf.

Okay ,, it can be only pushed when ANSI is on. Let me just enable aNSI for tihs test case:

    case Cast(child, dataType, _, evalMode)
        if evalMode == EvalMode.ANSI || Cast.canUpCast(child.dataType, dataType) =>
      generateExpression(child).map(v => new V2Cast(v, child.dataType, dataType))
      ```
