## Querying MySQL
|
|
|
|
1. Click on **+ Add** button of the query manager at the bottom panel of the editor.
|
|
2. Select the database added in the previous step as the data source.
|
|
|
|
Once the MySQL data source is added, you can create queries to read and write data to the database. You can create queries from the **[Query Panel](/docs/app-builder/query-panel#query-manager)** located at the bottom panel of the app builder.
|
|
|
|

|
|

|
|
3. Click on the **Run** button to run the query.

|
|
SELECT * FROM users
|
|
```
|
|
|
|
<div style={{textAlign: 'center'}}>

|
<img className="screenshot-full" src="/img/datasource-reference/mysql/sqlmode.png" alt="mysql" style={{marginBottom:'15px'}}/>
|
|
|
|
</div>
|
|
|
|
### GUI Mode
|
|
|
|
GUI mode can be used to query MySQL database without writing queries.

|
|
2. Choose the operation **Bulk update using primary key**.

3. Enter the **Table** name and **Primary key column** name.
|
|
4. In the editor enter the records in the form of an array of objects.
|
|
5. Click on the **Run** button to run the query.
|
|
|
|
**Example:**
|
|
|
|
```json
|
|
{{ [ {id: 1, channel: 33}, {id:2, channel:24} ] }}
|
|
```
