The implementation principle of paging in MySQL is achieved by using LIMIT and OFFSET. LIMIT is used to restrict the number of query results, while OFFSET is used to specify the starting position of the query results.<\/p>\n
When carrying out a pagination query, the first step is to determine the number of records to display per page (usually a fixed value), and then calculate the number of records to skip based on the current page number. Assuming 10 records are displayed per page, to show the data on the third page, you would need to skip the first 20 records.<\/p>\n
The specific SQL query is as follows:
\nSELECT * FROM table_name, retrieve 10 records starting from the 21st record.<\/p>\n
This statement will retrieve 10 records from the table_name table, starting from the 21st record, thus achieving pagination.<\/p>\n
In practical applications, one can determine the total number of pages by calculating the total number of records, thus enabling pagination. Additionally, the ORDER BY clause can be used to specify the sorting order of the query results.<\/p>\n
Please note that the OFFSET count starts from 0, meaning the offset of the first record is 0. Additionally, to improve query performance, you can add an index to the fields that need to be paginated.<\/p>\n","protected":false},"excerpt":{"rendered":"
