mysql - 删除和插入行mysql

Question

我必须更新表中的多行(最多大约 32 行)。目前我的代码可以删除指定的行但无法插入。我错过了什么吗？我的代码如下所示:

connection.query("DELETE FROM items WHERE record_id = ?", id, function (err, result) {
    if(err)
    { console.log("ERROR UPDATE" + err); }
    else
    { 
        console.log("entered UPDATE");
        // Loop through Hour Difference 
        for (var i = 1; i <= hours; i++) {

            // Avoiding Add in the first iteration
            if (i != 1) {
              start_date_time.add(1, "hours");
            }

          // Convert Date Format to MYSQL DateTime Format
          var myDate3 = moment(start_date_time.format('YYYY-MM-DD HH:mm:ss')).format("YYYY-MM-DD HH:mm:ss");
          console.log('Index update [' + i + ']: ' + myDate3);

          var data = {
              name: req.body.site_name,
              remarks: req.body.remarks,
              date_part: myDate3,
              record_id: id
          }

          connection.query("INSERT INTO items SET ?", [data], function (err, result) {
              if (err) {
                  console.log(err);
              } else {
                  console.log('Index [' + i + ']: INSERTED to update');
              }
          });
        }
    }
});

您的插入查询不正确。插入查询的正确语法是，

INSERT INTO TABLE_NAME (column1, column2, column3,...columnN)  
VALUES (value1, value2, value3,...valueN);

如果您使用SET，它应该是更新查询。更新查询的正确语法是，

UPDATE table_name
SET column1 = value1, column2 = value2, ...
WHERE condition;
