Changing data source connection properties

Change the connection properties of a data source by accessing the extensionProperties array of the DataSource object. The ODA extension defines the list of connection properties that can be set at run time.

Table 3-3 describes the JDBC data source properties that affect the connection.

Table 3-3 JDBC data source run-time connection properties
Property	Description
odaUser	Login user name
odaPassword	Login password
odaURL	URL that identifies the data source
odaDriverClass	Driver class for accessing the data source

To change these properties, add code similar to the statements in the data source beforeOpen script in Listing 3‑17.

Listing 3‑17 Changing data source connection properties in beforeOpen

extensionProperties.odaUser = "JoeUser";

extensionProperties.odaPassword = "openSesame";

extensionProperties.odaURL = "jdbc:my_data_source:xxx";

extensionProperties.odaDriverClass = "com.companyb.jdbc.Driver";

extensionProperties.odaJndiName = "java:/MySQLDs";

extensionProperties.OdaConnProfileName = "myprofile";

extensionProperties.OdaConnProfileStorePath = "c:/conprof";

Alternatively, set these properties using the following syntax:

this.setExtensionProperty("odaURL","jdbc:mysql://localhost/mysql");

The beforeFactory event also supports changing connection properties as shown in Listing 3‑18.

Listing 3‑18 Changing data source connection properties in beforeFactory

report = reportContext.getDesignHandle( );

dsHandle = report.findDataSource("Data Source");

dsHandle.setProperty("odaDriverClass", "myDriver");

dsHandle.setProperty("odaURL", "myUrl");

You can also set data source and data set properties using the property binding feature in the data source editor.
