Usage of limit in mysql (commonly used for data paging), mysqllimit

When we use a query statement, we often need to return the first few or a few rows of data in the middle. What should we do at this time? Don't worry, Mysql already provides us with such a function.

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 first return

The offset of the record row. 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; // retrieve record rows The Data from 6 to 15th 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.
