DROP删除表
GaussDB(DWS)与MySQL都支持使用DROP语句删除表,但GaussDB(DWS)不支持在DROP语句中使用RESTRICT | CASCADE关键字。DSC工具迁移时会将上述关键字移除。
输入示例

CREATE TABLE IF NOT EXISTS `public`.`express_elb_server`( `runoob_id` VARCHAR(10), `runoob_title` VARCHAR(100) NOT NULL, `runoob_author` VARCHAR(40) NOT NULL, `submission_date` VARCHAR(10) )ENGINE=InnoDB DEFAULT CHARSET=utf8; DROP TABLE `public`.`express_elb_server` RESTRICT; |
输出示例
1 2 3 4 5 6 7 8 9 10 11 |
CREATE TABLE IF NOT EXISTS "public"."express_elb_server" ( "runoob_id" VARCHAR(40), "runoob_title" VARCHAR(400) NOT NULL, "runoob_author" VARCHAR(160) NOT NULL, "submission_date" VARCHAR(40) ) WITH ( ORIENTATION = ROW, COMPRESSION = NO ) NOCOMPRESS DISTRIBUTE BY HASH ("runoob_id"); DROP TABLE "public"."express_elb_server"; |
