Create Connections
Understand Toad Connections
Review this topic to learn about open database connections in Toad.
For information about switching the current connection in Toad, see Switching Connections in Toad.
Toad Open Connections
In Toad, an open connection in the Connection/Navigation Manager represents one or more actual connections to the database
- Toad creates an initial database connection for general use.
-
Toad also creates a separate database connection for each Editor (the first time you execute a statement) and for each Data tab in the Database Explorer (the first time you select the tab and query data).
The connection associated with the window (or tab) remains open until you close the window. If a window has an associated connection, but a statement is not currently executing, the connection is in an inactive state.
To view information for an open connection
-
To view the number of actual database connections that exist for a Toad connection, including the number of active connections, place the cursor over the connection in the Connection/Navigation Manager pane or in the connection drop-down list.
To use the Background Processes pane
- When a statement is executing, a progress bar displays in the Status bar located at the bottom of the Toad application window. Click the executing progress bar to open the Background Processes pane.
-
To cancel statement execution, use the Background Processes pane.
Note: It is recommended that you cancel only your own processes, because terminating Toad activities could cause unexpected behavior.
Sharing a Connection Among Windows
You can instruct Toad to share an open connection among windows. In this way, the Editor windows and Data tabs can share the same connection when the connection is inactive.
To share a database connection among windows in Toad
- Select Tools | Options | Editor | General.
-
Clear the checkbox for the Use individual connection for each open editor option.
-
When this option is not selected, Toad attempts to use a single connection for any new windows or query execution. For example, if you share a database connection, you can execute a query in the Editor, execute another query in a new Editor, and then select the Data tab from the same connection.
If the single connection is in use when Toad attempts to execute it, the following occurs:
- (DB2 and Oracle only) If your database supports executing multiple queries simultaneously on a shared connection, the query is placed in a queue and executes as soon as the current operation completes.
- If your database does not support executing multiple queries on a shared connection, a dialog prompts you to either permanently associate the window with a new database connection, cancel the previous operation, or add the query to a queue until the current operation completes, and the execute it. If you place multiple queries in the queue, each one executes in the order that it was added to the queue.
Note: Although you can share a database connection, any commits apply to the selected window only.
Create Access Connections
Although this connection uses the ODBC driver, it is easier and faster to connect using this method. See Troubleshoot Access Issues for more information about troubleshooting connection issues.
Notes:
-
The Toad Sample Database and established connection that comes pre-loaded in Toad Data Point is an Access database. The connection information for this database is:
Database file = C:\Program Files\Quest Software\ToadInstallDirectory\Plugins\Odbc\Sample Database\Quest_Stage.mdb
Additional sample files for this database are available in the Project Manager.
To create an Access connection
-
Click
on the toolbar (ALT+F+N).
-
Select Access from the Group list box.
-
Review the following for additional information:
Database file
Select the database to use when connecting.
MDW file
Select the MDW file that is linked to the database.
Password
Enter the password to use when connecting.
Tip: After connecting, you can set a master password to further secure your connection in Tools | Options| Environment | Security.
Category Select or create a category if you want to color code Editor tabs for a specific connection. This can help differentiate between development and production databases. You can also set an option to color code the Object Explorer pane and object editor windows (Create, Alter, Drop, etc.).

Click Connect to connect immediately while saving the connection information. Optionally, click Save to save the connection without connecting.
Considerations and Limitations
| Consideration/Limitation | Description |
|---|---|
|
Microsoft Access 2016 64-bit Office 365 64-bit |
To successfully create a connection to an Access database using Microsoft Access 2016 64-bit, the Microsoft Access Database Engine is required and might not have been included in the Access installation. In addition, the architecture (bitness) of the engine must match the bitness of Toad. If using 64-bit Toad, the 64-bit version of Microsoft Access Database Engine is required. If using 32-bit Toad, the 32-bit version of Microsoft Access Database Engine is required.

Create BusinessObjects Connections
Toad allows you to connect to SAP® Business Objects through the Query as a Web Service (QaaWS) component to view and query data in QaaWS Queries.
See also, About SAP Business Objects Data Sources.
Note: This feature is available in the Toad Data Point Professional Edition only.
To create a Business Objects connection
- Click
- Select SAP Business Objects from the Group list.
-
Enter the connection information in the Create New Connection dialog. Review the following for additional information:
URL Enter the Business Objects URL to which you want to connect. This is the URL to the Query as a Web Service component of the Business Objects installation. See Important Information about Business Objects Connections for more information.
Note: The URL should be in the following format:
http://<server>:<port>/dswsbobje/qaawsservices
Password Enter the password to use when connecting.
Tip: After connecting, you can set a master password to further secure your connection in Tools | Options| Environment | Security.
Category (Optional) Select an existing category or create a new one. Note: In NoSQL and Business Intelligence connections, Toad automatically saves the password in the connections.xml file as obfuscated text, as well as in Toad. To add additional password security, use Toad's Master Password feature.
-
Click Connect to connect immediately while saving the connection information. Optionally, click Save to save the connection without connecting.
-
Upon creating an initial connection, Toad automatically maps the data source objects. This process runs in the background, and until it is finished, you may experience a delay when attempting to access these objects.
Important Information about Business Objects Connections
To create a Business Objects connection in Toad, you must connect to the Query as a Web Service component in Business Objects. The connection URL should have the format:
http://<server>:<port>/dswsbobje/qaawsservices
Where <server> corresponds to your web server address, and <port> corresponds to the port where you set up in your web server. (dswsbobje is the default name of the Query as a Web Service web application.)
An example URL is http://server01:8080/dswsbobje/qaawsservices.
For more information about the Business Objects component, Query as a Web Service, see the documentation at http://help.sap.com/businessobject/product_guides/xir2PP/en/qaaws.pdf.
Tips:
- To specify a default value for a column parameter, select a Query and click
.
- Read about the considerations and limitations of working with Business Objects in Toad in About SAP Business Objects Data Sources.
- Connections are stored in the connections.xml file and can be found by clicking the Application Data Directory link in Help | About.
- You can specify a proxy server to use for Business Intelligence and NoSQL connections at Tools | Options | Database | Data Services.
