Commit DB Documentation

The documentation is a work in progress...

Connect to your databases

Commit DB allows two distinct types of connection:

MySQL Direct connection

Login form

  • Host is either the IP address (V4 or V6) of your MySQL server or its fully qualified domain name (ie:
  • User is your MySQL user
  • Password is your MySQL user’s password
  • Database is the database you want to connect directly after the connection. This setting is optional and the database can be changed at anytime without reconnecting
  • Port is your MySQL server’s port
  • Socket should be filled only if your MySQL server is using a socket
  • Favorite allows you to have this connection appearing at the top of your saved connections. If the connection is not saved this setting does not do anything
  • Color allows you to choose a color to dinstinguish your connection. This color will appear on the icon in the connections list and in the top left of the screen in the SQL Editor and DB Browser panes
  • Read Only allows you to create a read-only session where no object can be created, modified or dropped. It’s also not possible to update / delete / insert rows.

If you want to save this connection you should then tap the “Save connection” button. This will put this connection in your saved connections list.

Then just tap the “Connect” button.

MySQL Connection through a SSH tunnel

  • Host should be
  • Ssh Host is the IP address or FQDN of the SSH server you’re trying to connect through
  • Ssh User is the username of the SSH server you’re trying to connect through
  • Ssh Password is the password of the SSH user
  • Ssh Key is the RSA private key used to authenticate the SSH user. Please note that the password and the key fields must not be used at the same time. It’s either one or the other.
  • Ssh Port is the port of the SSH server

The SSH keys can be imported by tapping the key icon SSH Keys manager. The procedure is the same as the one described for SSL certificates.

New SSH key

All other settings and interactions are the same as in a direct connection scenario.

Securing connection with SSL

  • Flip the Use SSL switch to ask Commit to secure your connection with SSL

If you need to provide keys and certificates for your server, tap the lockpad icon KeySets manager in the top left corner to invoke the KeySets manager.

KeySets manager UI

Tap the “+” icon to create a new KeySet or swipe to the left an existing one to delete it.

If you’re logged into iCloud, the KeySets created will be synced between all your connected devices.

Create new KeySet

  • Enter a unique name for your new KeySet in the Key Set Name field
  • Client key : if needed for your configuration, pick a client key PEM file with the iOS document picker by tapping the Client key line
  • Client CERT : if needed for your configuration, pick a client certificate PEM file with the iOS document picker by tapping the Client CERT line
  • CA CERT : if needed for your configuration, pick a CA certificate PEM file with the iOS document picker by tapping the CA CERT line

Using a KeySet

You then just have to select your KeySet in the SSL Key Set field of the connection form.

Saved connections

Typing connection information on a handled device is tiresome. To ensure that you do it the least possible amount of time, we included a Saved Connections feature.

Creating a new saved connection

Each time you tap the “Save Connection” button the currently defined connection is saved in the list with a label in the form of:


If your connection uses a SSH tunnel, its description will be prepended by “(SSH) “:

(SSH) mysql_user@mysql_host/mysql_database

The list of saved connections is accessible from the “Servers” button at the top left of the screen (or by putting your device in landscape)

Saved connections dialog

Deleting an existing saved connection

To delete an existing saved connection, just swipe right on it in the list and confirm by tapping the “Delete” button.

Deleting saved connection

Clearing the connection form

To clear the connection form of all its current values, tap the “Quick Connect” entry in the “Saved Connections” list.

Disconnect your current session

When you have an active connection, this connection will be materialized by a green line in the connections list. You can disconnect the connection by tapping it in the list.

You can also disconnect your current connection by tapping the current connection button and then selecting the “Disconnect current connection”.

Current connection dialog


Security settings

Use “Touch ID”

This setting will allow you to protect the access of the app with a touch ID prompt. Of course, this feature will only works if Touch ID is already activated and configured on your device.

Touch ID prompt

If the authentification fail, you will have to either wait for the app to become inactive or to kill it with the task manager to try again.

Performance settings

Retrieve full dataset

If this setting is turned to “ON” the app will fetch all the rows of any query it executes. The default behaviour is to only fetch the number of rows specified in the “Rows in Dataset” setting.

Turning this setting on may severely affect performances

Rows in Dataset

It’s the number of rows that are retrieved by the app by default. No effect if the “Retreive full dataset” setting is set to “ON”.

Include All Rows In Exports

When you’re exporting a dataset to another app, should all the rows be exported or only the ones currently visible in the app ?

Other settings

Allow screen to go off

If this setting is turned to “OFF” your device screen will never dim and turn off while you’re using the app. This will allow you to perform more easilly long running queries.

SQL Editor

Database selector

The database selector let’s you choose the database you’re working on. Just roll your finger on the list to change the current database.

Database selector

Db objects browser

The “Db objects browser” let you view the names of the following objects present in your database:

  • Tables
  • Views
  • Fields
  • Indexes
  • Constraints

DB objects browser

You can filter the objects presented by searching their name with the help of the “search” field at the top.

Tapping on an object of the list will insert its name in the code editor at the current insertion point. This is intended to speed up the typing of your queries in the editor.

Code editor

The “Code Editor” let’s you type and execute your queries. To start typing, just tap the “Tap to enter query” message.

You can have as many queries as you like in the editor at the same time. You don’t need to end them by a semi-column (“;”) to separate your different queries. You only need to have at least one blank line between them.

Once your query has been executed, your results will be displayed in a table view just beneath the code editor. You can swipe up/down and left/right on the table view to scroll the results.

If you have not modified the “Retrieve full dataset” setting you may have only a subset of the full resultset in the table view. If you want to see the full resultset you have to use the “Show all results” button.

You can sort the resulset by tapping the column name. On first tap, the dataset is sorted in an ascending order. On the second tap, the dataset is sorted in a descending order.


Start transaction

Start transaction

By tapping the “Start transaction” button   Start transaction button   you will be offered the choice of the type of transaction you wish to start. Once you have selected a type of transaction, the “Start transaction” button will be replaced by a “Commit”   Start transaction button   and a “Rollback”   Start transaction button   buttons.

Import code

The “Import code” button   Import code button   will let you import a text file from any storage provider app installed on your device (iCloud, Dropbox, OneDrive, Google Drive … etc.).

Export file

The “Export file” button   Export file button   will let you choose between three different actions:

Export file dialog

  • “Dataset” : to export a CSV or JSON file of the current resultset present in the table view
  • “Export SQL script” : to export the queries present in the code editor to any storage provider (iCloud, Dropbox, OneDrive, Google Drive … etc.) present on your device
  • “Share SQL script” : to open the iOS standard share sheet to share the queries present in the code editor

Clear code editor

The “Clear editor” button   Clear editor button   will remove all the queries currently in the code editor.

Hide / show DB objects

The “Hide DB objects” button   Hide DB objects button   will hide the DB objects browser from view. The “Show DB objects” button   Show DB objects button   will restore it into view.

Hide results

The “Hide results” button   Hide results button   will hide the current resultset to leave a maximum of screen space to the code editor.

Show all results

The “Show all results” button   Show all results button   will transition you to a paginated view of all the rows in your current resultset.

Run query

The “Run query” button   Run query button   will execute the currently selected query.

Keyboard shortcuts

  • ⌘ + R : run the current query
  • ⌘ + N : clear the code editor
  • ⌘ + G : show full resultset
  • ⇧ + ⌘ + N : start a new transaction

DB Browser tab

The “DB Browser” let you see and inspect all the objects in your database.

DB Objects browser

DB Objects browser

The “DB Objects browser” works mostly like the SQL editor one’s. But you can here choose the typez of objects you’re interrested in inspecting:

  • “Ta” : Tables
  • “V” : Views
  • “R” : Routines (functions and stored procedures)
  • “Tr” : Triggers
  • “I” : Indexes and constraints

Selecting one of the item in the list will load its information in the data grid.

Data Grid

Data grid

The data grid has the following subtabs :

  • “Columns” : let you see the columns of a table / view, the parameters of a routine, the event on which occurs a trigger or the columns of an index / constraint
  • “Indexes” : list the indexes of a table
  • “Constraints” : list the constraints of a table
  • “Triggers” : list the triggers of a table
  • “Data” : show the data of a table / view, just as a “select * from table_name” would
  • “Grants” : show the grants of a table
  • “Stats” : show the stats of a table
  • “Script” : show thez creation script of any object

Edit Mode

Turning the “Edit Mode” ON will allow you to drop objects, add new lines in tables or to modify data from tables.

Drop object

To drop a linked object, you just have to tap its line in the data view. A dialog will ask you confirmation before proceding.

Insert new line in table

Select the name of the table in which you want to insert a new row and select the Data tab. The ”+” will then activate. Tap it to insert a new row.

Insert new row

Enter the value you want for each field and then tap “Save” to save the row or “< Back” to come back to the previous screen without saving.

The primary key fields, if any, will appear in red.

Edit row data

To enter the edit mode, tap the line number of the row you want to edit. The app will ask you if you want to edit or delete the row. Select “EDIT” to proceed to the edit screen.

Edit row

You can then modify the fields you want to change and either “Save” or ”< Back”. Please note that the constraints existing on your table are not checked at input time but only when you will try to save the row. If the constraints are violated an error message will appear and no change will have been written to the database.

Delete a row from a table

To delete a line of data, you have to tap the line number on the left of the to get the confirmation dialog. If you tap a data cell, you will be taken to a detail view of the cell where you can change its value (only if “Edit Mode” is ON).


Refresh data

Tapping the “Refresh” button   Run query button   will refresh the current pane of the data view.

Export data

The “Export” button   Export button   will let you export a CSV or JSON file of the current pane of the data view.

Hide / show DB objects

The “Hide DB objects” button   Hide DB objects button   will hide the DB objects browser from view. The “Show DB objects” button   Show DB objects button   will restore it into view.

Data row details

You can get a detailed view of all the fields in a data row by tapping it’s line number while you’re in read-only mode.

You will then see a scrollable page with one field per line.
