AVG_ROW_LENGTH

在MySQL中，AVG_ROW_LENGTH表示平均每行的长度。 GaussDB (DWS)不支持此属性，并在迁移过程中被DSC删除。

输入示例

     
          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)
)AVG_ROW_LENGTH=10000;

输出示例

     
          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");
