Create a Microsoft SQL Server connection
To access your data stored on a Microsoft SQL Server database, you will need to know the server and database name that you want to connect to, and you must have access credentials. Once you have created a connection to a Microsoft SQL Server database, you can select data from the available tables and then load that data into your app or document.
In Qlik Sense, you connect to a Microsoft SQL Server database through the Add data dialog or the Data load editor.
Setting up the database properties
This field will only appear if you selected the "via Direct Access gateway" data connection. Select the data gateway through which you need to connect to your data source.
Information noteUsers that need to leverage gateway-enabled data connections must have the Can Consume Data permission for the space with which the gateway is associated.
|Server||Host name to identify the location of the Microsoft SQL Server database||Yes|
|Port||Server port for the Microsoft SQL Server database||Yes|
|Database||The name of the Microsoft SQL Server database||Yes|
|Encrypt||Select to use encrypted communication with the database server.||No|
Select the minimum version of TLS (Transport Layer Security) supported by the Microsoft SQL Server. If you select 1.0 and the servers runs 1.2, the connector will accept the connection. If you select 1.2 and server runs 1.1, the connector will not accept the connection.
Warning noteSSL v3 is no longer supported by the Microsoft SQL Server Connector.
|CA Certificate||Path to file system location of the root CA certificate||Yes, when Encrypt is selected|
|Trust Server Certificate||Rely on the CA certificate provided by the server to verify secure data transfer.||No|
Authenticating the driver
The ODBC Connector Package's Microsoft SQL Server Connector does not support single sign-on (SSO) in:
- Qlik Sense Desktop
- Qlik Sense SaaS
Qlik Sense: Microsoft SQL Server credentials
Use the Kerberos single sign-on service specified in the Server SPN property.
Information noteWhen a connection is created or edited with Single Sign-On selected, the connection uses the credentials of the user who is currently logged into Qlik Sense.
If a user ID is specified for the Delegation UID property, then the connection is tested with the user ID specified in the Delegation UID property and the password for the Delegation UID. Any time the connection properties are changed, the password for the Delegation UID must be reentered to test or save the changes to the connection.
Use the NTLM (NT LAN Manager) security protocol for authentication.
Information noteNTLM cannot be used when Single Sign-On is selected.
|Required when the user is registered with NTLM for authentication on the database server. Cannot be used if the user's credentials are not registered with NTLM on the database server.|
|Server SPN||The service principal name (SPN) for the Microsoft SQL Server.||Yes, when Single Sign-On is selected.|
The user ID to use for scheduled, automatic reloads. If a Delegation UID is specified, it is also used to test the connection when it is created or edited. The ID must be entered in the format domain\username.
Information noteManual reloads always use the ID of the user who is logged into Qlik Sense, not the Delegation UID.
No, but the ID can be provided when Single Sign-On is selected.
Information noteBecause scheduled reloads are performed under a system account instead of a real user, Single Sign-On may not be necessary, The scheduled reloads can be performed using predefined NTLM authentication.
|User name||User name for the Microsoft SQL Server connection.||Yes, when Single Sign-On is not selected.|
Password for the Microsoft SQL Server connection.
Information noteWhen Single Sign-On is selected, the password is for the user identified with the Delegation UID. If a user is not specified in the Delegation UID property, then Password property must be left blank for single sign-on (SSO).
|Yes, when Single Sign-On is not selected.|
|Name||Name of the Microsoft SQL Server connection. The default name will be used if you do not enter a name.||Yes|
Credentials are used to prove that a user is allowed to access the data in a connection.
There are two types of credentials that can be used when making a connection in Qlik Sense SaaS. If you leave the User defined credentials check box deselected, then only one set of credentials will be used for the connection. These credentials belong to the connection and will be used by anyone who can access it. For example, if the connection is in a shared space, every user in the space will be able to use these credentials. This one-to-one mapping is the default setting.
If you select User defined credentials, then every user who wants to access this connection will need to input their own credentials before selecting tables or loading data. These credentials belong to a user, not a connection. User defined credentials can be saved and used in multiple connections of the same connector type.
In the Data load editor, you can click the underneath the connection to edit your credentials. In the hub or Data manager, you can edit credentials by right-clicking on the connection and selecting Edit Credentials.
|User defined credentials||Select this check box if you want users that access this connection to have to input their own credentials. Deselect this check box if credentials can be shared with anyone who has access to this connection.|
|New credentials||Drop-down menu item that appears if User defined credentials is selected.|
|Existing credentials||Drop-down menu item that appears if User defined credentials is selected.|
|User||User name for the connection.|
|Password||Password for the connection.|
|Credentials name||Name given to a set of user defined credentials.|
Load optimization settings
|Max String Length||
Maximum length of string fields. This can be set from 256 to 16384 characters. The default value is 4096. Setting this value close to the maximum length may improve load times, as it limits the need to allocate unnecessary resources. If a string is longer than the set value, it will be truncated, and the exceeding characters will not be loaded.
