将整数传递给查询时，NodeJS MySQL返回空数组

Question

SECOND EDIT

The issue was caused by the MAX_INTEGER_VALUE which is lower then the integer value I was passing. I changed the MySQL table column to TEXT instead of BIGINT and everything is being returned correctly.

Thanks for all the help!

EDIT

So I just realized that the userID variable and the guildID variables are being passed using this line of code.

mysqlModule.userCrewSearch(575783451018526744, 282997056438665217);

However the values that are being supplied to the SQL statement turn the last two digits of the number into '00'. So instead of 575783451018526744 the value being passed into the SQL statement is 575783451018526700 .

So why is this value being changed when nothing I am doing in my code is changing these values?

Original Post

I'll keep this short and sweet. I'm trying to run a query using the nodejs MySQL package. I'm not sure where I'm going wrong but whenever I call my function that executes my query, I'm always returned an empty array, unless I hardcode the values into the SQL query.

Heres the code:

// Search for the User's Crew
function userCrewSearch(guildID, userID) {
    pool.getConnection(function(err, connection) {
        if(err) { 
            return console.log(err);
        }
        var sql = "SELECT * FROM `crew-members` WHERE `userID`=? AND `guildID`=?;";
        console.log(sql);
        connection.query(sql, [guildID, userID], function(err, results) {
            connection.release(); // always put connection back in pool after last query
            if(err) { 
                return console.log(err);
            }
            return console.log(results);
        });
    });
}

I'm calling this function like so: userCrewSearch(575783451018526744, 282997056438665217);

Both of the values I'm passing are integers. However this is what I get in my console.

However, here is my code with the values hardcoded into the SQL... to which the code then returns the result in the form of a RowDataPacket.

// Search for the User's Crew
function userCrewSearch(guildID, userID) {
    pool.getConnection(function(err, connection) {
        if(err) { 
            return console.log(err);
        }
        var sql = "SELECT * FROM `crew-members` WHERE `userID`=282997056438665217 AND `guildID`=575783451018526744;";
        console.log(sql);
        connection.query(sql, [guildID, userID], function(err, results) {
            connection.release(); // always put connection back in pool after last query
            if(err) { 
                return console.log(err);
            }
            return console.log(results);
        });
    });
}

Heres the result.

Bonus Question: How do I handle the RowDataPacket? Can I convert this directly into an object so I can call results.crewID and return just that value?

Answer 1

Same problem i was facing few days ago. I have solved this by converting the parameters into string.

function userCrewSearch(String(guildID), String(userID)) {

       //  your code here 
}

Answer 2

Try adding + before your numeric parameter, it converts into number, it worked for me-

connection.query(sql, [+guildID, +userID], function(err, results) {

for your bonus questions answer, you can directly access the crewID or some other key using,

results[0].crewID

or do something like -

const [ result ] = results;
console.log(result.crewID)
