Error : The label '@' has already been declared. Label names must be unique within a query batch or stored procedure.

Answer

Use bulk

const table = new sql.Table('CLASS_TABLE');
table.columns.add('NAME', sql.NVarChar(15), {nullable: false});
table.columns.add('ROLL', sql.Int, {nullable: false});
table.columns.add('CLASS', sql.Int, {nullable: false});
table.columns.add('MARKS', sql.Int, {nullable: false});

values.forEach(arr => table.rows.add.apply(null, arr));

const request = new sql.Request();
request.bulk(table, (err, result) => {
  // ... error checks
});
