问题 What's the equivalent to SQL Server's TOP or DB2's FETCH FIRST or mySQL's LIMIT in PostgreSQL? 回答1: You can use LIMIT just like in MySQL, for example: SELECT * FROM users LIMIT 5; 回答2: You could always add the OFFSET clause along with LIMIT clause. You may need to pick up a set of records from a particular offset. Here is an example which picks up 3 records starting from 3rd position: testdb=# SELECT * FROM COMPANY LIMIT 3 OFFSET 2; This would produce the following result: id | name | age |
