sqoop抽数报错Every derived table must have its own alias

报错如下：

ERROR manager.SqlManager: Error executing statement: java.sql.SQLSyntaxErrorException: Every derived table must have its own alias

修改前脚本：

--query "select * from (select APPNO,COMPANY from cs.gf_app t ) where $CONDITIONS " \

修改后脚本：

--query "select * from (select APPNO,COMPANY from cs.gf_app t ) t1 where $CONDITIONS " \

报错原因：

子查询需要加上别名
