When we use the query statement, often to return the first few or the middle of a few lines of data, this time how to do? Do not worry
MySQL has provided us with such a feature.
SELECT * FROM table LIMIT [offset,] rows | Rows Offset Offset
The LIMIT clause can be used to force a SELECT statement to return the specified number of records. LIMIT accepts one or two numeric parameters. Parameter must
is an integer constant. Given two arguments, the first parameter specifies the offset of the first row to return the record, and the second parameter specifies the return
Maximum number of record rows. The offset of the initial record line is 0 (instead of 1): For compatibility with PostgreSQL, MySQL also supports sentences
fa: LIMIT # OFFSET #.
Mysql> SELECT * FROM table LIMIT 5, 10; Retrieve Record Row 6-15
To retrieve all row rows from an offset to the end of a recordset, you can specify a second argument of-1:
Mysql> SELECT * from table LIMIT 95,-1; Retrieves the record row 96-last.
If only one argument is given, it represents the maximum number of record rows returned:
Mysql> SELECT * from table LIMIT 5; Retrieve the first 5 rows of records
In other words, LIMIT n is equivalent to LIMIT 0,n.
