Create ODBC Connections
Toad Data Point allows you to create a connection to a database that supports an ODBC 3.0 or later driver. ODBC connectivity provides basic querying capability, but may not be as full-featured as a native connection in Toad. For a list of databases tested with the ODBC provider, see the Release Notes.
This form of connectivity allows connections to databases such as Netezza, IBM iSeries, Ingres, and Vertica.
Note: Distinct values are not available in Code Completion for ODBC connections.
DSN Architecture (Bitness) Must Match Toad
To create a successful ODBC connection, the architecture (bitness) of the driver in the specified DSN must match the architecture (bitness) of Toad. For example, 64-bit Toad requires an applicable 64-bit driver and 32-bit Toad requires an applicable 32-bit driver.
To create an ODBC connection
- Click
on the toolbar (ALT+F+N+O).
- Select ODBC Generic from the Group list box.
- Use data source name—Select to display data source names. Clear this check box if you want to display the driver names.
- To create a data source to use in this connection, click
in the Data Source Name field. Then click Add.
-
Select an ODBC driver from the list, and click Finish.
Note: If creating an Oracle ODBC connection, select the ODBC driver provided by Oracle. The Microsoft ODBC for Oracle driver has less functionality than the driver provided by Oracle.
-
Specify the configuration properties required for the database in the Windows configuration dialog.
Notes:
- If you have an Oracle database with Unicode data, make sure to select Force SQL_WCHAR Support on the Workarounds tab of the windows Oracle ODBC Configuration dialog. If you do not, you will not be able to see the data.
- If creating a MySQL ODBC connection to use in a cross-connection query, you must specify a database in the Windows MySQL ODBC Configuration dialog.
-
Specify the connection properties in the Create New Connection dialog. Review the following for additional information:
General Data source name
Select the driver or data source name you added in the previous steps.
User
Enter the user name to use when connecting.
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.

Tips for Working with ODBC Connections
| Tip | Description |
|---|---|
| Filter DSN by bitness |
To filter Data Source Names displayed in the New Connection dialog by the bitness of Toad, go to Tools | Options | Database | ODBC. |
| Cache object metadata |
To cache object metadata for ODBC connections and retain it between sessions, go to Tools | Options | Database | ODBC and select to enable disk caching. Cached object metadata is retained until manually refreshed. |
| Refresh object metadata |
To refresh object metadata for all ODBC connections, in the Object Explorer right-click an object and select Refresh All. Right-click an object and select Refresh Schema to refresh only objects in that schema. |
ODBC Features
| Feature | Description |
|---|---|
| Bypass schema/instance selection in SQL Editor |
For ODBC connections, in the SQL Editor you can bypass selecting a schema/instance and specify this information through the script instead. This is useful if your script executes SQL against multiple schemas. To use this method, select I will set schema/instance in the script from the schema/instance drop-down list in the SQL Editor window. Then specify the schema/instance through your script. Note: When this option is selected, some code completion features, object actions, and object information tool tips are unavailable for this SQL Editor window. |
Create Oracle Connections
You can create a new connection, or connect to an existing connection from the Create New Connection window.
Tip: You can configure Toad Data Point to accept connection information from Toad for Oracle.
Client Connection or Direct Connection
You can connect to your database using a native Oracle database provider in Toad using one of the following methods:
|
Connection Method |
Advantages |
Disadvantages |
|---|---|---|
|
Client connection Client tab—Uses an installed Oracle Client or Oracle Instant Client to establish a connection to the database from Toad. |
Supports LDAP See Configure Oracle LDAP Support for more information about configuring the Oracle client to use LDAP. |
Requires an Oracle client Note: Toad supports Oracle clients and Oracle Instant clients using version 9i or later. |
|
Direct connection Direct Connect tab—Uses TCP/IP to connect directly to the database. |
Does not require an installed Oracle Client Recommended for connecting to Oracle 8i databases |
This method only supports common data types. Some advanced Oracle object types cannot be retrieved when connecting using this method. This method does not support LDAP. (To connect using LDAP, use the Client Connection method instead.) This method cannot be used in a cross-connection query. |
|
Note: Quest recommends using one of the methods described in this table to connect to Oracle rather than an ODBC driver. Because ODBC connectivity is generic, it is not full-featured and may not be as robust as the fully exploited native database provider. | ||
Data Types Supported
Toad supports both the 32-bit and the 64-bit versions of the Oracle Client. The following table identifies which Oracle data types are supported for each client type.
| Data Type | Supported Using 32-Bit Client |
Supported Using 64-Bit Client |
|---|---|---|
| CHAR |  |
|

|
Table Notes:
- An XMLType that uses an XML schema is supported, but only when using Oracle Client 11.2 or later.
- XMLType data that is stored as binary XML is not supported.
Configure the Oracle Instant Client
The Oracle Instant client installs only those files needed to connect to your database using OCI. Because this client does not write to the registry (no ORACLE_HOMES) or add to the environmental path, you must manually set environment variables so the client can be used with Toad.
To configure the Oracle Instant Client to work with Toad
- Save the Oracle Instant Client files in any location on the computer where Toad is installed.
- On your Windows desktop, right-click My Computer and select Properties.
- Select the Advanced tab and click Environment Variables.
-
Click New under System Variables and complete the following:
Variable name Variable Value PATH <Path where Instant Client is installed>;%PATH%
For Example: C:\Program Files\OracleInstantClient;%PATH%
TNS_ADMIN <Path where tnsnames.ora file is installed>
- To use the Oracle Instant Client connection in a cross-connection query, you must also install an Oracle ODBC driver. (While the Oracle Client full install includes an ODBC driver, the Oracle Instant Client does not.)
Note: You cannot use an Oracle Direct Connection in a cross-connection query.

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.
