Microsoft SQL Server Non-Spatial Reader Parameters

About Database Connections

Database formats include a Database Connection parameter that defines and stores authentication information. For general information about sharing database connections, please see Using Database Connections. Using Database Connections.

Note that Database Connection parameters differ slightly, depending on context and/or database format.

Connection

From the Connection parameter in a database format, you can do one of the following:

    Select an existing, previously defined connection. See the section Reusing a Database Connection in Using Database Connections

    Select Add Database Connection to define a new connection. See database-specific parameters below, as well as the section Adding a Database Connection in a Workspace in Using Database Connections The new connection can be made visible only to the current user, or can be shared among multiple users.

Connection Parameters (Add Database Connection dialog)

Server

The host name of the Microsoft SQL Server or Azure SQL Database. (It is not necessary to specify a port if a default configuration is used.)

If you have configured your Microsoft SQL Server database to use a non-standard port number, you can specify this port here.

The correct syntax is:

<Host>[\<Instance>][:<port>]

Database

To initiate a database connection, enter (or browse for) the database name.

Authentication

  • SQL Server Authentication – Select this option to proceed with specifying login credentials through the Username and Password parameters.
  • Windows Authentication – Select this option when connecting through a Windows user account, and the database can validate the account name and password using the Windows principal token in the operating system. Since the user account is retrieved by Windows, the Username and Password parameters are ignored.

Username and Password

Enter the username and password to access the service.

Encrypt Connection

Note   This parameter is not present in the Azure SQL Database reader and writer. The Azure SQL Database reader and writer will always request Secure Sockets Layer (SSL) encrypted connections.

When selected, this parameter requests Secure Sockets Layer (SSL) encryption for the connection. If the server does not have a certificate trusted by the client machine, the connection will fail. Otherwise, data will be encrypted before traveling over the network. There are multiple ways to trust a server certificate on a client machine.

If this parameter is not selected, encryption behavior will be determined by encryption properties set for SQL Server Native Client, and for SQL Server.

Tip   When Encrypt Connection is selected, please provide a fully qualified Server name. For example, a server named safe-sql-server might have a fully qualified name of safe-sql-server.dev.safe. This fully qualified name should be an exact match for the server name on the trusted certificate.

Multi-Subnet Failover

Enable this option if you are connecting to a SQL Server that has been configured for High Availability (HA).

Constraints

WHERE Clause

This optional specification is used to limit the rows read by the reader from each table. This example selects only the features whose lengths are more than 2000:

LENGTH > 2000

Advanced

Application Intent

Declares the application workload type when connecting to a server in an Always On environment.

  • ReadWrite (default) – The driver connects to a read-write node.
  • ReadOnly – The client requests a read workload when connecting. The server enforces the intent at connection time.
