> While testing the 4.0.0-rc1, I have found the internal error on the new
> feature:
> {code:sql}
> spark-sql (default)> CREATE TEMPORARY FUNCTION fa(x INT) RETURNS TABLE (a
> INT) RETURN SELECT x;
> Time taken: 0.325 seconds
> spark-sql (default)> select * from fa(1);
> {code}
> {code:java}
> [INTERNAL_ERROR] SQL table function plan should be rewritten during analysis:
> SQLTableFunction fa,
> SQLFunction(fa,Some(StructType(StructField(x,IntegerType,true))),Right(StructType(StructField(a,IntegerType,true))),None,Some(SELECT
> x),None,Some(true),None,true,HashMap(referredTempFunctionsNames -> [],
> catalogAndNamespace.part.0 -> spark_catalog, referredTempViewNames -> [],
> catalogAndNamespace.part.1 -> default,
> sqlConfig.spark.sql.artifact.isolation.enabled -> false,
> catalogAndNamespace.numParts -> 2,
> sqlConfig.spark.sql.datetime.java8API.enabled -> true,
> referredTempVariableNames -> []),None,1740153099265), [1], [a#3]
