# Update Rows

### Update a Specific Row

You can update a single specific row in a [Data Store](https://docs.catalyst.zoho.com/en/cloud-scale/help/data-store/introduction) table using the `update()` method. This enables you to update the values of one or more columns of the row by passing the modified values of the columns as key-value pairs.

The `<ROW_INSTANCE>` used in the code syntax below is the instance defined in the [Row Instance page](https://docs.catalyst.zoho.com/en/sdk/android/v2/cloud-scale/data-store/create-row-instance).

```bash
<ROW_INSTANCE>.update(
    success: (ZCatalystRow) → Unit,
    failure: ((ZCatalystException) → Unit)?
): ZCatalystRequest<ZCatalystResponse<ArrayList<ZCatalystRow>>>?

```

A sample code snippet is shown below:

```bash
ZCatalystApp.getInstance().getDataStoreInstance().getTableInstance("EmployeeDetails").getRow(2823000000095003, //Replace this with your table name and the ROWID of the row
    {
        row -> row.setColumnValue("Employee_Name", "Morgan Jones")
        row.update(
            {
                success -> println("Row updated successfully $success")
            },
            {
                exception -> println("Failed to update the row $exception")
            }
        )
    })

```

### Update all Rows

You can update multiple row in a table by passing an array of the rows as an argument to the `updateRows()` method. This enables you to update the values of one or more columns of the rows, by passing the modified values of the columns as key-value pairs.

The `<TABLE_INSTANCE>` used in the code below is the instance defined in the [Table Instance page](https://docs.catalyst.zoho.com/en/sdk/android/v2/cloud-scale/data-store/create-table-instance).

```bash
<TABLE_INSTANCE>.updateRows(
    rows: ArrayList<ZCatalystRow>,
    success: (List<ZCatalystRow>) → Unit,
    failure: ((ZCatalystException) → Unit)?
): ZCatalystRequest<ZCatalystResponse<ArrayList<ZCatalystRow>>>?

```

**Parameters**:

* `rows`: The array of rows to be updated

A sample code snippet is shown below:

```bash
ZCatalystApp.getInstance().getDataStoreInstance().getTableInstance("EmployeeDetails").updateRows( //Replace this with your table name
    rowsList, //Set the names and values of the columns and add them to an arrayList
    {
	    println(">>>> Rows updated successfully $it")
    },
    {
         println(">>>> Update Rows Failed $it")
    })

```
