When we use a query statement, the distinct operator often returns the first few or several rows of data in the middle. What should we do at this time? Don't worry,MysqlThis feature has been provided for us. SELECT * FROM table LIMIT [offset,] rows | rows OFFSET

The LIMIT clause can be used to force the SELECT statement to return the specified number of records. LIMIT accepts one or two numeric parameters. The parameter must be an integer constant. If two parameters are specified, the first parameter specifies the offset of the first returned record row, and the second parameter specifies the maximum number of returned record rows. The OFFSET of the initial record row is 0 rather than 1. To be compatible with PostgreSQL, MySQL also supports Syntax: LIMIT # OFFSET #.

Mysql> SELECT * FROM table LIMIT 5, 10; // retrieves records FROM 6 to 15 rows.

// To retrieve all record rows from an offset to the end of the record set, you can specify the second parameter-1:
Mysql> SELECT * FROM table LIMIT 95,-1; // retrieves 96-last records.

// If only one parameter is specified, it indicates the maximum number of record rows returned:
Mysql> SELECT * FROM table LIMIT 5; // retrieve the first five record rows

// In other words, LIMIT n is equivalent to LIMIT 0, n.
