MySQL插入错误: ER_BAD_FIELD_ERROR: Unknown column '2525' in 'field list'

Question

var convID = 2525;
var contactUsername = 'blabla';
var userId = 100;
var contactId = 200;

var sql = "INSERT INTO contacts (FK_OWNERID, FK_USERID, FC_CONTACTNAME, `CONVERSATION_ID`)
                     VALUES (" + mysql.escape(userId) + "," + mysql.escape(contactId) + "," + mysql.escape(contactUsername) + "," + convID + "),
                     (" + mysql.escape(contactId) + "," + mysql.escape(userId) + "," + mysql.escape(username) + "," + convID + ")";

`错误:ER_BAD_FIELD_ERROR:“字段列表”中的未知列“2525” CONVERSATION_ID 和 FC_CONTACTNAME 的字段均为 varchar(32)，另外 2 个字段为 int。

这个查询有什么问题？我什至在 CONVERSATION_ID 周围加上了反引号，它认为 convID 变量是一列...

编辑:

如果我的查询就是这样，那么它就有效:

        var sql = "INSERT INTO contacts (`FK_OWNERID`, `FK_USERID`, `FC_CONTACTNAME`)
                 VALUES (" + mysql.escape(userId) + "," + mysql.escape(contactId) + "," + mysql.escape(contactUsername) + "),
                 (" + mysql.escape(contactId) + "," + mysql.escape(userId) + "," + mysql.escape(username) + ")";

Answer 1

制作

" + convID + "

到

'" + convID + "'

很可能它是一个字符串，数据类型是 varchar，所以你需要用单引号括起来。
