JSON Types

Overview

The JSON data type can be used to store JavaScript Object Notation (JSON) data. DSC supports the following type conversions:

Type Mapping

Input Example (JSON)

CREATE TABLE IF NOT EXISTS `runoob_dataType_test`(
    `dataType_1` INT,
    `dataType_2` VARCHAR,
    `dataType_3` JSON
);
ALTER TABLE `runoob_dataType_test` ADD COLUMN `dataType_4` JSON NOT NULL;
ALTER TABLE `runoob_dataType_test` CHANGE COLUMN `dataType_4` `dataType_5` JSON NOT NULL;

Output

CREATE TABLE IF NOT EXISTS "public"."runoob_datatype_test"
(
  "datatype_1" INTEGER,
  "datatype_2" VARCHAR,
  "datatype_3" JSONB
)
  WITH ( ORIENTATION = ROW, COMPRESSION = NO )
  NOCOMPRESS
  DISTRIBUTE BY HASH ("datatype_1");
ALTER TABLE
  "public"."runoob_datatype_test"
ADD
  COLUMN "datatype_4" JSONB;
ALTER TABLE
 "public"."runoob_datatype_test" CHANGE COLUMN "datatype_4" "datatype_5" JSONB;
