Create SAP HANA Connection
Note: This topic focuses on information that may be unfamiliar to you. It does not include all step and field descriptions.
To create an SAP HANA connection
- Click
on the toolbar (ALT+F+N).
- Select SAP HANA from the Group list box.
-
Specify the connection properties in the Create New Connection dialog. Review the following for additional information:
General tab Description Host
Enter IP address (or the master host name).
Note: Enter the master host name. Host names for distributed systems are determined automatically. If the specified host is not available, the connection is established through one of the other hosts.
Instance Number
Enter a two-digit instance number.
Note: The communication port number is defined by: n <instance> xy, where n is either 3 or 5, <instance> is a two-digit number representing the instance number of the SAP HANA appliance, and xy represents a consecutive number. Toad users only enter the instance number.
Type of Authentication
Select:
Authentication by the current operating system user - connect using your operating system authentication
Authentication by the database user - connect using your database user authentication
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.
Mode
Select the database mode. SAP HANA supports numerous isolated databases in a single HANA system. Although each database in a multiple-container system is isolated, cross-queries can be performed and all databases share the same installation, resources, and administration.
Single-container — Select for single-container systems. These can be converted to multiple-container systems.
Multiple-container — Select for multiple-container systems. These systems always have one system database, which is used for administration, and any number of tenant databases.
Select whether you want to connect to the System or Tenant database. Users connect to a specific tenant database within the system using its database name.
Current Schema
Select a database schema. Click
to create a temporary connection and display available schemas in the drop-down list.
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.
Tip: Connections are stored in the connections.xml file and can be found by clicking the Application Data Directory link in Help | About.
Create Teradata Connections
Toad allows you to create a full-featured, native Teradata connection. This type of connection provides complete Query Builder, Query Editor, and Database Explorer functionality.
Notes:
- You must have a Teradata .NET Data Provider installed before you can create a Teradata connection.
- To use a Teradata connection in a cross-connection query, you must have a Teradata ODBC driver installed.
To install the Teradata data provider
| » | Download and install the Teradata .NET Data Provider from the Teradata Web site. Use the version supported by your database version. |
To create a Teradata connection
- Click
- Select Teradata from the Group list.
-
Enter the connection information in the Create New Connection dialog. Review the following for additional information:
Login Server name
Enter the name of the server hosting the database to which you want to connect. Use Single Sign On
Select if the user is using a single sign-on authentication system. 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.
Session mode
Displays the session mode, which is always Teradata in a Toad Teradata connection.
Default database
(Optional) Enter a default Teradata database for the connection. Category
(Optional) Select an existing category or create a new one. Advanced
Mechanism
(Optional) Select an authentication mechanism from the list. Parameter
(Optional) Enter the parameters required by the selected authentication mechanism. See your system administrator for these values. Account string
(Optional) Enter a new account string. Character set
Select a character set.
Note: When querying or viewing data in a column defined with GRAPHIC or CHARACTER SET GRAPHIC data type, you must specify a Character set of UTF-16 for the session.
Use data encryption
Select if using data encryption. Response buffer size
Specify a Response Buffer Size (in bytes). This allows you to govern the number of rows returned in a single response. To increase the number of rows per response, increase the response buffer size. This strategy might help to improve performance with larger data sets.
The default value in Toad is set to the maximum, 1040000 bytes.

To install a Teradata ODBC driver
| » | Download and install a Teradata ODBC driver from the Teradata Web site. For a list of supported Teradata ODBC drivers, please see the Release Notes for your version of Toad for SAP Solutions. |
Notes:
- Toad does not support the Teradata multi-statement request.
- You can specify which Teradata Data Directory views to use, X views or Non-X views, in Tools | Options | Database | Teradata.
Troubleshoot Connections
Troubleshoot Access Issues
Review the following solutions to help troubleshoot Access issues pertaining to missing functionality and object information and other problems in Toad.
See Create Access Connections for more information about Access connections.
Missing Functionality and Object Information
| Issue | Cause/Solution |
|---|---|
|
Some queries display in the View tab of the Object Explorer, but do not display in the Query tab. |
The Access ODBC driver handles saved queries in the following manner:
|
|
Primary key information is unavailable. |
The Microsoft Access ODBC driver does not return primary key information for databases. However, in some cases, Toad can obtain this information through additional methods. |
Other Issues
| Issue | Cause/Solution |
|---|---|
|
A delay occurs between writing a value to a database via one connection and seeing the updated value via another connection. |
This delay is the default when you are writing and reading data between two different Jet connections. The delay occurs even if the two connections reside in the same client process. Solution: Use a single connection when updating data. |
