CLUSTERED KEY

It is a clustered index in ADB that defines the sorting sequence in a table. The logical sequence of key values in a clustered index determines the physical sequence of rows in the table. GaussDB(DWS) does not support table definition modification using this attribute. DSC will delete the keyword during migration.

Input

drop table if exists unsupport_parse_test;
create table `unsupport_parse_test` (
    `username` int,
     clustered key clustered_key(shopid ASC, datetype ASC)
);
drop table if exists unsupport_parse_test;

Output

DROP TABLE IF EXISTS "public"."unsupport_parse_test";
CREATE TABLE "public"."unsupport_parse_test" (
  "username" INTEGER
) WITH (ORIENTATION = ROW, COMPRESSION = NO) NOCOMPRESS DISTRIBUTE BY HASH ("username");
DROP TABLE IF EXISTS "public"."unsupport_parse_test";
