有谁知道如何SELECT WHERE IN
在 node-mysql 中使用?
我尝试了下面的代码,但收到以下错误消息:
'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''(`PHP`,`apache`)'' at line 1'
这是我的代码:
whereIn = '(';
for ( var i in tagArray ) {
if ( i != tagArray.length - 1 ) {
whereIn += "`" + tagArray[i] + "`,";
}else{
whereIn += "`" + tagArray[i] + "`";
}
}
whereIn += ')';
console.log(whereIn);
client.query(
'SELECT tag_id FROM tag WHERE tag_name IN ?',
[whereIn],
function(err, result, fields) {
client.destroy();
if (err) {
throw err;
}
console.log(result);
res.redirect('/');
}
);
