How to push JSON data to an array with duplicate values in java script










1















I have to return all the data which is present in the table_name without any removal of duplicate values, till the console i can see all the records from db , once it is pushed to an array1 then my repeated records got disappeared.
I want to return all the records.



 db.query('SELECT * FROM table_name ORDER BY name', function(err, data) 
if (err) return next(err);
var array = ,
array1 = ;
for (var i = 0; i < data.rows.length; i++)
if (array[data.rows[i].name]) continue;
array[data.rows[i].name] = true;
console.log(array[data.rows[i].name])// till here
array1 .push(data.rows[i])


return res.status(200).send(array1 );
);

    Change the entire function below the err handler to return data.rows.

I am not sure why you are using multiple arrays, hope this will help you



db.query('SELECT * FROM table_name ORDER BY name', function(err, data) 
if (err) return next(err);
var array = ,
array1 = ;
for (var i = 0; i < data.rows.length; i++)
if (array[data.rows[i].name]) continue;
array[data.rows[i].name] = true;
array1 .push(data.rows)

return res.status(200).send(array1 );
);

    You are adding properties to the array variable in the first line of the loop, using the name property from data. If some other row exists with the same name, the item won't be added.
