# Update Rows

> **Note:** This SDK is currently in deprecation. Migrate to [JavaScript SDK](https://docs.catalyst.zoho.com/en/sdk/javascript/v1/cloudscale/datastore/update-rows/) now.

You can update a single row or multiple rows in a table in the
[Catalyst Data Store](https://docs.catalyst.zoho.com/en/cloud-scale/help/data-store/introduction), and update one more
column values. The `table` reference used in the below code snippets can either be a
[table instance](https://docs.catalyst.zoho.com/en/sdk/nodejs/v2/cloud-scale/data-store/get-table-instance) or the
[table meta.](https://docs.catalyst.zoho.com/en/sdk/nodejs/v2/cloud-scale/data-store/get-table-meta)

### Update a Single Row

This particular method allows you to update a single row by constructing a object with altered values in the required
column. Refer the unique **ROWID** and pass the newly constructed Object to the
`updateRow()` method. Here **ROWID** is a mandatory attribute. The promise
returned here will be resolved to a JSON row object.

```javascript
//Construct a JSON Object with the updated row details 
let updatedRowData = { Name: `Mathew Jones`, Age: 31, ROWID: 1510000000109474 }; 
//Use Table Meta Object to update a single row using ROWID which returns a promise 
let datastore = app.datastore(); 
let table = datastore.table('SampleTable'); 
let rowPromise = table.updateRow(updatedRowData);
rowPromise.then((row) => { console.log(row); });
```

A sample response that you will receive is shown below. The response is the same for both versions of Node.js.

#### Node.js 

```javascript
{
CREATORID: "2136000000006003",
MODIFIEDTIME: "2021-08-17 13:02:11:184",
CREATEDTIME: "2021-08-16 16:29:10:499",
Name: "Mathew Jones",
Age: 31,
ROWID: "2136000000011011"
}
```

### Update Multiple Rows

To update multiple rows, an array of objects is constructed containing modified values which is passed as an argument to
the `updateRows()` method. **ROWIDs** are used in corresponding array objects to refer the specific rows which requires modification.

The promise returned here will be resolved to an array of row objects.

```javascript
//Data to be updated along with the ROWID 
let updatedRowsData = [{ Name: `Mathew Jones`, Age: 31, ROWID:
1510000000113298 }, { Name: `Rhonda Watson`, Age: 28, ROWID: 1510000000109474 }]; 
//Use Table Meta Object to update a multiple rows using ROWIDs which returns a promise 
let datastore = app.datastore(); 
let table = datastore.table('SampleTable'); 
let rowPromise = table.updateRows(updatedRowsData); 
rowPromise.then((rows) => {
console.log(rows); 
});
```
