How Can I Perform Bulk Inserts into MySQL Using Node.js?

Bulk Inserting Data into MySQL using Node.js with MySQL

If you're utilizing node-mysql, there are various methods to execute bulk inserts into MySQL. One approach involves employing nested arrays to group values for insertion:

Nested Arrays Implementation

Within the SQL query, specify the VALUES clause as a question mark (?) to indicate the placeholder for values to be inserted.

INSERT INTO Test (name, email, n) VALUES ?

Prepare the data as a nested array, with each sub-array representing a row to be inserted:

var values = [
    ['demian', '[email protected]', 1],
    ['john', '[email protected]', 2],
    ['mark', '[email protected]', 3],
    ['pete', '[email protected]', 4]
];

Next, pass the array of arrays to the query method as an argument:

conn.query(sql, [values], function(err) {
    if (err) throw err;
    conn.end();
});

In this example, values is a nested array wrapped in another array.

Alternative Bulk Insertion Package

There exists another Node.js package specifically designed for bulk insertion into MySQL:

• node-mysql-bulk-insert:
