The SELECT statement in MySQL is used to retrieve data from a database.<\/p>\n

The general syntax of a SELECT statement is as follows:<\/p>\n

SELECT \u5217\u540d\u6216\u8868\u8fbe\u5f0f\r\nFROM \u8868\u540d\r\n[WHERE \u6761\u4ef6]\r\n[ORDER BY \u5217\u540d [ASC | DESC]]\r\n<\/code><\/pre>\n
The column names or expressions are used to specify the data columns to retrieve, and * can be used to retrieve all columns. The table name is used to specify the table from which to retrieve data. The WHERE clause is used to specify the conditions for retrieving data. The ORDER BY clause is used to specify the sorting order of the retrieval results, with the default being in ascending order.<\/p>\n
Here are some examples of SELECT statements:<\/p>\n
    \n
  1. Retrieve data from all columns.<\/li>\n<\/ol>\n
    SELECT * FROM \u8868\u540d;\r\n<\/code><\/pre>\n
      \n
    1. Retrieve data from specified columns.<\/li>\n<\/ol>\n
      SELECT \u5217\u540d1, \u5217\u540d2 FROM \u8868\u540d;\r\n<\/code><\/pre>\n
        \n
      1. Retrieve data that meets the criteria.<\/li>\n<\/ol>\n
        SELECT * FROM \u8868\u540d WHERE \u6761\u4ef6;\r\n<\/code><\/pre>\n
          \n
        1. Retrieve and sort by specified column.<\/li>\n<\/ol>\n
          SELECT * FROM \u8868\u540d ORDER BY \u5217\u540d ASC;  -- \u5347\u5e8f\u6392\u5e8f\r\nSELECT * FROM \u8868\u540d ORDER BY \u5217\u540d DESC; -- \u964d\u5e8f\u6392\u5e8f\r\n<\/code><\/pre>\n
            \n
          1. Search specific column and sort by specified column.<\/li>\n<\/ol>\n
            SELECT \u5217\u540d1, \u5217\u540d2 FROM \u8868\u540d ORDER BY \u5217\u540d1 ASC, \u5217\u540d2 DESC;\r\n<\/code><\/pre>\n
            The above are just some common usages of the SELECT statement, there are more advanced techniques like using aggregate functions and limiting the number of results with LIMIT. In practice, the SELECT statement can be used flexibly according to specific needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
