How to use Navicat code to delete data

When using code to delete data in Navicat, you need to follow the following steps ：

Step one: Establish a connection

  1. Open Navicat and connect to the database where you want to delete data.
  2. Click "Object" > "Table" and select the table from which you want to delete data.

Step 2: Open the table in the editor

  1. Right-click on the table and select Edit Data.
  2. This will open the table in a new editor window.

Step Three: Write the Delete Query

  1. In the editor window, click the "SQL" tab.
  2. In the SQL editor, enter the following code: 
<code class="sql">DELETE FROM <表名>
WHERE <条件></code>
Copy after login

Where:

  • <Table Name>: The name of the table from which to delete data.
  • <Conditions>: Conditions for deleting data. This condition can be based on any column in the table.

Step Four: Run the Query

  1. Make sure the correct SQL Editor tab is selected.
  2. Click the Run button (usually a green triangle icon) to run the query.

Step 5: Confirm deletion

  1. The system will prompt you to confirm the deletion operation.
  2. Click "Yes" to confirm and delete the data.

Example:

To delete all customers over 60 years old from the table named "Customers", you can use the following code:

<code class="sql">DELETE FROM Customers
WHERE Age > 60</code>
Copy after login
