Using a Connection String

For some applications, you might need to use a connection string to connect to your data source. For detailed information about how to use a connection string in an ODBC application, refer to the documentation for the application that you are using.

The connection strings in the following sections are examples showing the minimum set of connection attributes that you must specify to successfully connect to the data source. Depending on the configuration of the data source and the type of connection you are working with, you might need to specify additional connection attributes. For detailed information about all the attributes that you can use in the connection string, see Driver Configuration Options on page 1.

DSN Connection String Example

The following is an example of a connection string for a connection that uses a DSN:

DSN=[DataSourceName]

[DataSourceName] is the DSN that you are using for the connection.

You can set additional configuration options by appending key-value pairs to the connection string. Configuration options that are passed in using a connection string take precedence over configuration options that are set in the DSN.

DSN-less Connection String Examples

Some applications provide support for connecting to a data source using a connector without a DSN. To connect to a data source without using a DSN, use a connection string instead.

Important:

When you connect to the data store using a DSN-less connection string, the connector does not encrypt your credentials.

The placeholders in the examples are defined as follows, in alphabetical order:

  • [DatabaseName] is the database that you want to access.
  • [PortNumber] is the number of the TCP port that the PostgreSQL server uses to listen for client connections.
  • [PPort] is the number of the TCP port that the proxy server uses to listen for client connections.
  • [PServer] is the IP address or host name of the proxy server to which you are connecting.
  • [Server] is the IP address or host name of the PostgreSQL server to which you are connecting.
  • [ServiceName] is the Kerberos service principal name of the PostgreSQL server.
  • [YourPassword] is the password corresponding to your user name.
  • [YourUserName] is the user name that you use to access the PostgreSQL server.

Connecting to a PostgreSQL Server Using Standard Authentication

The following is the format of a DSN-less connection string for a basic connection to a PostgreSQL server:

Driver=Simba PostgreSQL ODBC Driver;
Server=[Server];Port=[PortNumber];
Database=[DatabaseName];UseKerberos=0;
UID=[YourUserName];PWD=[YourPassword];

For example:

Driver=Simba PostgreSQL ODBC Driver;Server=192.168.222.160;
Port=5400;Database=TestDB;UseKerberos=0;UID=simba;
PWD=simba;

Connecting to a PostgreSQL Server Using Kerberos Authentication

The following is the format of a DSN-less connection string for connecting to a PostgreSQL using Kerberos authentication:

Driver=Simba PostgreSQL ODBC Driver;
Server=[Server];Port=[PortNumber];
Database=[DatabaseName];UseKerberos=1;
UID=[YourUserName];KerberosServiceName=[ServiceName];

For example:

Driver=Simba PostgreSQL ODBC Driver;Server=192.168.222.160;
Port=5400;Database=TestDB;UseKerberos=1;
UID=simba;KerberosServiceName=simba_postgresql;

Connecting to a PostgreSQL Server Through a Proxy Server

The following is the format of a DSN-less connection string for connecting to a PostgreSQL server through a proxy server:

Driver=Simba PostgreSQL ODBC Driver;
Server=[Server];Port=[PortNumber];
Database=[DatabaseName];UseKerberos=0;
UID=[YourUserName];PWD=[YourPassword];
ProxyHost=[PServer];ProxyPort=[PPort];

For example:

Driver=Simba PostgreSQL ODBC Driver;Server=192.168.222.160;
Port=5400;Database=TestDB;UseKerberos=0;UID=simba;
PWD=simba;ProxyHost=192.168.222.160;
ProxyPort=8000;
