How to retrieve the top 10 data in a mysql sorting operation?
You can use the LIMIT clause to fetch the first n records, along with the ORDER BY clause for sorting.
For example, to sort a field of a table in ascending order and retrieve the top 10 data, you can use the following statement:
SELECT * FROM 表名 ORDER BY 字段名 ASC LIMIT 10;
To sort in descending order, you can change ASC to DESC.
Please note that the asterisk (*) represents selecting all fields, but you can also specify specific fields.
Additionally, the LIMIT clause can also specify the starting position, for example, to retrieve data from the 11th to the 20th row, you can use the following statement:
SELECT * FROM 表名 ORDER BY 字段名 ASC LIMIT 10, 10;
The first “10” here indicates the starting position, meaning to start from the 11th data entry. The second “10” indicates the number of entries to be retrieved, which is 10 entries.
To sum up, sorting and selecting the top n records can be done using ORDER BY and LIMIT.
