- 1、相当与mysql的show databases;
- select datname from pg_database;
- 2、相当于mysql的show tables;
- SELECT table_name FROM information_schema.tables WHERE table_schema = ‘public‘;
public 是默认的schema的名字
- 3、相当与mysql的describe table_name;
- SELECT column_name FROM information_schema.columns WHERE table_name =‘table_name‘;
- ‘table_name‘是要查询的表的名字
