This article will explain in detail the methods of querying the first 30 pieces of data on mysql. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

How mysql queries the first 30 items of data can be viewed by executing the [SELECT * FROM data table name LIMIT 0,30;] statement. LIMIT can receive one or two numeric parameters, but the parameters must be integer constants.

SQL statement:

SELECT * FROM table LIMIT 0,30

LIMIT receives one or two numeric parameters.

Parameter must be an integer constant. Given two parameters, the first parameter specifies the offset of the first returned record row, and the second parameter specifies the maximum number of record rows returned. The offset of the initial record row is 0 (not 1).

This is the end of the method of querying the first 30 pieces of data on mysql. I hope the above content can be of some help to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
