CONNX ODBC DRIVER

However the option is available and it is up to each admin to determine the risk of these features based on the project and security needs. But, it also results in slower performance due to the time it takes to transfer data from the surrogate process to the main SQL Server process and also the load time of the driver in the surrogate process. SQL Server typically reserves all but a small amount of memory for itself. Enable promotion of distributed transactions for RPC When enabled, SQL Server will automatically start a distributed transaction when a stored procedure is executed via the third-party driver. Some databases do not require a username and password to connect. This is usually sufficient to access any resources required by the driver. To enable these ad-hoc methods execute the following commands:

This option should be turned on. Creating a new linked server from the Management Studio. Building a linked server connection Building a linked server connection requires a couple of ingredients: Use Remote Collation If the collation of a column in the other database is different than the default collation on the SQL Server, SQL Server will honor the column collation as specified by the linked server instead of re-sorting the data using the default SQL Server collation if this option is enabled.

If at all possible, do not use a single set of authentication credentials for all linked server connections. It should be enabled.

Obviously, this needs to be turned on. Once all options for the new linked server have been set, press OK to create the linked server. For most third-party drivers, this has no performance impact.

Specifying the linked server driver connection properties. SQL Server typically reserves all but a small amount of memory conn itself. Many third-party providers do not support nested queries.

Please refer to the oebc detailed SQL Server documentation on this stored procedure if desired. The solution to the problem is provided on the following dialog. But they do support accessing data via indexes. If set to true: Here, a static set of credentials for the other database will be used for all linked server connections.

Tree view of tables available via a linked server connection. And for a fully compliant driver that supports both catalog and owner names, like CONNX, it would look like this:.

Lazy Schema Validation If set to true: For example if a provider does not support catalog names, but does support owner names, the syntax would look like this:. Once the driver has been selected, fill in the remaining fields.

The surrogate process provides complete isolation of the third-party driver and the SQL Server database engine. Then, expand the catalog until you can see your tables. But it is required to complete the linked server connection. After selecting the name of your linked server connection, you must decide what type of driver to use to access the non-SQL Server database.

Can somebody give me a hint, how to establish a fully working connection? This option is normally not enabled. This gives the third-party driver its own separate memory space. Specifying the authentication method for the linked server connection.

The huge disadvantage of using the four-part name syntax is performance. If the collation of a column in the other database is different than the default collation on the SQL Server, SQL Server will honor the column collation as specified by the linked server instead of re-sorting the data using the default SQL Server collation if this option is enabled.

When enabled, SQL Server will automatically start a distributed transaction when a stored procedure is executed via the third-party driver.
