MySQL 使用 WHERE 子句直接 INSERT INTO

MySQL direct INSERT INTO with WHERE clause(MySQL 使用 WHERE 子句直接 INSERT INTO)

问题描述

我尝试用谷歌搜索这个问题，但只找到了如何使用两个表来解决问题，如下所示，

I tried googling for this issue but only find how to do it using two tables, as follows,

INSERT INTO tbl_member
SELECT Field1,Field2,Field3,... 
FROM temp_table
WHERE NOT EXISTS(SELECT * 
         FROM tbl_member 
         WHERE (temp_table.Field1=tbl_member.Field1 and
               temp_table.Field2=tbl_member.Field2...etc.)
        )

这适用于一种情况，但现在我的兴趣是直接从程序本身上传数据，而不使用两个表.我想要的是上传不在表格中的数据.我脑子里的sql是这样的，

This worked for one scenario,But now my interest is to upload data directly from the program itself without using two tables. What i want is to upload the data which is not in the table. The sql i had in my head was like the following,

INSERT INTO tbl_member (SensorIdValue, DataTimeValue, DataInValue, IncompleteValue, SpiValue, InfoValue)
VALUES ('Sensor.org', '20121017150103', 'eth0','','','')
WHERE (SensorIdValue != 'Sensor.org'AND DataTimeValue != '20121017150103'AND DataInValue != 'eth0'AND IncompleteValue != ''AND SpiValue != ''AND InfoValue != '');

但这是错误的..请我知道正确的做法，非常感谢:)

But it's wrong.. may i know the proper way of doing it please, Thank you very much :)

推荐答案

INSERT 语法不能有 WHERE 子句.只有在使用 INSERT INTO...SELECT 语句时，您才会发现 INSERT 有 WHERE 子句.

INSERT syntax cannot have WHERE clause. The only time you will find INSERT has WHERE clause is when you are using INSERT INTO...SELECT statement.

第一个语法已经正确.
