Specify Database On a Server

Each SAP Sybase IQ server may have one or more databases loaded at a time. The URL as described above specifies a server, but does not specify a database. The connection attempt is made to the default database on the server.

You can specify a particular database by providing an extended form of the URL in one of the following ways.

Using the ServiceName Parameter

jdbc:sybase:Tds:machine-name:port-number?ServiceName=DBN

The question mark followed by a series of assignments is a standard way of providing arguments to a URL. The case of ServiceName is not significant, and there must be no spaces around the = sign. The DBN parameter is the database name.

Using the RemotePWD Parameter

A more general method allows you to provide additional connection parameters such as the database name, or a database file, using the RemotePWD field. You set RemotePWD as a Properties field using the setRemotePassword() method.

Here is sample code that illustrates how to use the field.

sybDrvr = (SybDriver)Class.forName(
	 "com.sybase.jdbc2.jdbc.SybDriver" ).newInstance();
props = new Properties();
props.put( "User", "DBA" );
props.put( "Password", "SQL" );
sybDrvr.setRemotePassword( 
	null, "dbf=asiqdemo.db", props );
Connection con = DriverManager.getConnection(
	"jdbc:sybase:Tds:localhost", props );

Using the database file parameter DBF, you can start a database on a server using jConnect. By default, the database is started with autostop=YES. If you specify a DBF or DBN of utility_db, then the utility database is started automatically.

IQ specific connection parameters from TDS clients should be specified in RemotePWD.

This example shows how to specify IQ specific connection parameters, where myconnection becomes the IQ connection name:

p.put(“RemotePWD“,“,,CON=myconnection”);

where myconnection becomes the IQ connection name.
