ALTER TABLE RENAME

GaussDB(DWS)不支持rename子句包含schema名，因此DSC工具只支持同schema下的rename。同schema下rename，转换结果去掉子句schema，跨schema的rename报错。

ALTER TABLE `shce1`.`t1` rename to `t2`;
ALTER TABLE `shce1`.`t1` rename to t2;
ALTER TABLE `charge_data`.`group_shengfen2022` RENAME `charge_data`.`group_shengfen2022_jiu`;
ALTER TABLE `charge_data`.`group_shengfen2022` RENAME `charge_data`.`group_shengfen2022_jiu`, RENAME `charge_data`.`group_shengfen2023_jiu`, RENAME `charge_data`.`group_shengfen2024_jiu`;
