Example: Create a Table Containing JSON Type Columns
In this example, the employee table is created with the following columns that store JSON data:
- json1 stores JSON data as text in the default character set of the user (LATIN or UNICODE)
- json2 stores JSON data using the BSON storage format
- json3 stores JSON data as text in UNICODE
- json4 stores JSON data using the UBJSON storage format
- json5 stores JSON data as text in the default character set of the user
CREATE TABLE employee (
id INTEGER,
json1 JSON(20),
json2 JSON(25) STORAGE FORMAT BSON,
json3 JSON(30) CHARACTER SET UNICODE,
json4 JSON(1000) STORAGE FORMAT UBJSON,
json5 JSON(5000));
Example: Add JSON Type Columns to a Table
The following ALTER TABLE statements add 3 JSON type columns to the jsonTable table.
CREATE TABLE jsonTable(id INTEGER); ALTER TABLE jsonTable ADD j1 JSON; ALTER TABLE jsonTable ADD j2 JSON STORAGE FORMAT BSON; ALTER TABLE jsonTable ADD j3 JSON STORAGE FORMAT UBJSON;
Example: Altering the Maximum Length and Inline Length
CREATE TABLE jsonTable (id INTEGER,
/* non-LOB */ jsn1 JSON(1000) CHARACTER SET LATIN,
/* LOB */ jsn2 JSON(1M) INLINE LENGTH 30000 CHARACTER SET LATIN);
ALTER TABLE jsonTable ADD jsn1 JSON(2000); ALTER TABLE jsonTable ADD jsn2 JSON(2M) INLINE LENGTH 30000 CHARACTER SET LATIN;
