PyCharm 2019.3 Help

Submitting changes to a database

In PyCharm, you can select how you want to commit transactions: automatically or manually. To change the commit mode, use the Tx drop-down menu on the toolbar.

If you submit a change to the database server and the commit mode is set to Auto, each change of values, rows, or columns is implicitly committed and cannot be rolled back. In the Auto commit mode, Commit The Commit button and Rollback The Rollback button buttons are disabled. You can submit your changes by clicking the Submit button The Submit button.

If the commit mode is set to Manual, you can explicitly commit or roll back submitted changes by clicking Commit The Commit button or Rollback The Rollback button buttons. To submit changes to a database, click the Submit button The Submit button.

The Tx switch can also be used for selecting the isolation level for the transactions.

Change the transaction level

Submit changes manually

By default, changes in tables are not submitted automatically. At first, you make changes in your local copy of the table, then you need to submit all changes to a database.

To submit changes to a database, click the Submit icon (The Submit icon), or press Ctrl+Enter.

Submit changes automatically

By default, changes are not submitted to a database unless you press the Submit icon The Submit icon, or press Ctrl+Enter. You can enable the Submit changes immediately option to submit your changes automatically.

  1. In settings Ctrl+Alt+S, navigate to Database | Data Views.

  2. Select Submit changes immediately.

  3. Click OK.

Revert changes

Before you submit the changes, you can revert them.

The scope of the revert command is defined by the current selection in a table: the command is applied only to the changes within the selection. So you can revert an individual change, a group of changes or all the changes. If nothing is currently selected, the revert command is applied to the whole table.

To revert non-submitted changes, select and right-click a cell or a number of cells. Select Revert Selected Ctrl+Alt+Z.

Resolving conflicts when submitting changes

It might happen that someone has changed the piece of code that you have been editing. In this case, when you try to submit your code to a database, PyCharm displays a notification that there is a conflict and you can resolve it by using a three-way merge.

  1. Click Merge.

  2. In the diff dialog, review your local changes and changes that were received from a server.

    Use the Ignore (the Ignore button) button to reject the change. Or, Accept (the Accept button or the Accept button) buttons to apply the change from the left or right pane. The middle pane shows the result of the merge operation.

  3. Click Save changes and finish merging.
