Databases
In MySQL, DATABASE is a schema object, which is equivalent to the SCHEMA concept in Oracle and GaussDB A. The following two scenarios are considered for DSC:
- Database creation
create database IF NOT EXISTS dbname1 CHARACTER SET=utf8 COLLATE=utf8_unicode_ci; create database IF NOT EXISTS dbname2; drop database if exists dbname1; drop database if exists dbname2;
Output
CREATE SCHEMA "dbname1"; CREATE SCHEMA "dbname2"; DROP SCHEMA IF EXISTS "dbname1"; DROP SCHEMA IF EXISTS "dbname2";
- Database use
drop database if exists test; create database if not exists test; use test; Output DROP SCHEMA IF EXISTS "test"; CREATE SCHEMA "test"; SET CURRENT_SCHEMA = "test";
