There are three ways to update data in MySQL in batch:<\/p>\n

    \n
  1. By using the UPDATE … SET … WHERE statement, you can specify multiple update operations in a single UPDATE statement. For example, you can use multiple conditions and multiple SET clauses to update multiple rows of data. For instance:<\/li>\n<\/ol>\n
    UPDATE table_name\r\nSET column1 = value1, column2 = value2, ...\r\nWHERE condition;\r\n<\/code><\/pre>\n
      \n
    1. By using the INSERT … ON DUPLICATE KEY UPDATE statement, you can update or insert data if there is a conflicting unique key or primary key in the table. For example:<\/li>\n<\/ol>\n
      INSERT INTO table_name (column1, column2, ...)\r\nVALUES (value1, value2, ...)\r\nON DUPLICATE KEY UPDATE\r\ncolumn1 = value1, column2 = value2, ...;\r\n<\/code><\/pre>\n
        \n
      1. You can utilize the LOAD DATA INFILE statement to efficiently update a large amount of data by storing it in a file and then loading the file into a table. For example:<\/li>\n<\/ol>\n
        LOAD DATA INFILE '\/path\/to\/file.csv'\r\nINTO TABLE table_name\r\nFIELDS TERMINATED BY ',' \r\nLINES TERMINATED BY '\\n'\r\n(column1, column2, ...);\r\n<\/code><\/pre>\n
        The above are common methods for bulk updating data, the specific method used depends on the amount of data and requirements.<\/p>\n","protected":false},"excerpt":{"rendered":"
