LOB Types

Overview

A BLOB is a binary large object that can hold a variable amount of data. The four BLOB types are TINYBLOB, BLOB, MEDIUMBLOB, and LONGBLOB. The only difference between these four types is the maximum length of the values they can contain. DSC supports the following type conversions:

Type Mapping

Input: [TINY|MEDIUM|LONG]BLOB

CREATE TABLE IF NOT EXISTS `runoob_dataType_test`(
    `dataType_1` BIGINT,
    `dataType_2` TINYBLOB,
    `dataType_3` BLOB,
    `dataType_4` MEDIUMBLOB,
    `dataType_5` LONGBLOB
);

Output

CREATE TABLE IF NOT EXISTS "public"."runoob_datatype_test"
(
  "datatype_1" BIGINT,
  "datatype_2" BLOB,
  "datatype_3" BLOB,
  "datatype_4" BLOB,
  "datatype_5" BLOB
)
  WITH ( ORIENTATION = ROW, COMPRESSION = NO )
  NOCOMPRESS
  DISTRIBUTE BY HASH ("datatype_1");
