if ( !err ) {
if( result.length ) {
result[0]['abc'].def[0]['new_key'] = 'blah';
response['success'] = true;
response['result'] = result[0]['abc'].def;
response['msg'] = 'data fetch';
res.json(response);
} else {
response['success'] = false;
response['result'] = '';
response['msg'] = 'No record found';
res.json(response);
}
} else {
response['success'] = false;
response['result'] = '';
response['msg'] = 'Error';
res.json(response);
}
});
