Previous post I will refer to later
I am making a Discord bot which uses MySQL, but that shouldn't matter, I am trying to do a blacklist database so users in it can't use my bot
This is what I got so far:
con.query("SELECT EXISTS( SELECT 1 FROM `blacklist` WHERE `id` = '"+message.author.id+"')", function(error, result, field) {
if(error) throw error;
});
And this kinda works, this is my output
[ RowDataPacket {
'EXISTS( SELECT 1 FROM `blacklist` WHERE `id` = \'227090776172134400\')': 1 } ]
And the last digit works like a boolean, 1 if the row exists, 0 if it does not But my problem is, that I can't seem to figure out how to check if it's a zero or not because it's an object
Why can't you make the query string a variable that you can later query on. For example:
let conStr = "SELECT EXISTS( SELECT 1 FROM `blacklist` WHERE `id` = '"+message.author.id+"')";
con.query(conStr, function(error, result, field) {
if(error) throw error;
console.log(result[conStr]); //--> 1
});
