I have never studied mysql in the system. I want to query the first n records today and habitually input SQL Server's select top n statements. An error is reported. Check that mysql can implement related functions through limit, and more powerful, GOOD. The following describes how to use limit in mysql: Syntax:
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; // retrieve the Row 6-15 of the record. Note that 10 is the offset.
// 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 // that is, LIMIT n is equivalent to LIMIT 0, n.
