COLLATE

In MySQL, COLLATE specifies a default database sorting rule. GaussDB(DWS) does not support table definition modification using this attribute. DSC will delete the keyword during migration.

Input

CREATE TABLE `public`.`runoob_tbl_test`(
    `runoob_id` VARCHAR(30),
    `runoob_title` VARCHAR(100) NOT NULL,
    `runoob_author` VARCHAR(40) NOT NULL,
    `submission_date` VARCHAR(30)
) COLLATE=utf8_general_ci;

ALTER TABLE `public`.`runoob_tbl_test` COLLATE=utf8mb4_bin;

Output

CREATE TABLE "public"."runoob_tbl_test"
(
  "runoob_id" VARCHAR(120),
  "runoob_title" VARCHAR(400) NOT NULL,
  "runoob_author" VARCHAR(160) NOT NULL,
  "submission_date" VARCHAR(120)
)
  WITH ( ORIENTATION = ROW, COMPRESSION = NO )
  NOCOMPRESS
  DISTRIBUTE BY HASH ("runoob_id");
