> In -SPARK-33460---
> there is a bug as follow.
> GetMapValueUtil generated code error when ANSI mode is on
>  
> s"""throw new NoSuchElementException("Key " + $eval2 + " does not exist.");"""
> should be 
> s"""throw new java.util.NoSuchElementException("Key " + $eval2 + " does not exist.");"""
>  
> But Why are
> checkExceptionInExpression[Exception](expr, errMsg)
> and sql/testOnly org.apache.spark.sql.SQLQueryTestSuite – -z ansi/map.sql
> can't detect this Bug
>  
> it's because 
> 1. checkExceptionInExpression is some what error, too. it should wrap with 
> withSQLConf(SQLConf.CODEGEN_FACTORY_MODE.key like CheckEvalulation, AND WE SHOULD FIX this later.
> 2. SQLQueryTestSuite ansi/map.sql failed to detect because of the ConstantFolding rules, it is calling eval instead of code gen  in this case
>
