   > @SbloodyS Because HiveStatementParser using druid uses 'SELECT t.* FROM ( %s ) t WHERE 0 = 1' to parse the column name with a temporary table （t.a,t.b）.so i need replace it
   
   @fuchanghai 
   The 'SELECT t.* FROM ( %s ) t WHERE 0 = 1' statement is in the method `tryExecuteSqlResolveColumnNames`, In the previous step using HiveStatementParser in the `tryGrammaticalAnalysisSqlColumnNames` method did not resolve the column names. Is there an exception?
