com.sas.storage.jdbc
Class JDBCToComboBoxModelAdapter

com.sas.storage.jdbc.JDBCToComboBoxModelAdapter

All Implemented Interfaces:

com.sas.table.StaticColumnInfoInterface, com.sas.util.transforms.DisplayTransformInterface, javax.swing.ComboBoxModel, javax.swing.ListModel

public class JDBCToComboBoxModelAdapter
implements javax.swing.ComboBoxModel

The JDBCToComboBoxModelAdapter allows JDBC data sources to be displayed in any viewer that requires a model of type javax.swing.ComboBoxModel, mainly being a javax.swing.JComboBox.

The adapter requires a java.sql.Connection object and a query statement. They can be passed in on the constructor or set via methods. The setConnection() method will apply the connection object. The setQueryStatement() method will apply the SQL query statement. When non-null values for both connection and query statement have been applied, the adapter is initialized and ready to use.

The query statement must be a SQL query that is valid for the JDBC data source. This may include a blank statement, if valid.

The setTemplateText method can be used to control which column values from the result set are displayed in the list. Multiple column values can be used along with text. The template text uses the default marker, open, and close characters from com.sas.util.SimpleTemplate( "%", "(", and ")" ). The column names must be defined in the template text as all uppercase variables. If no template text is defined, only the values from the first column of the result set are used as list items.

The general form of the template text is:

 text %COL1 more text %COL2
 
 Where COL1 and COL2 are fully uppercased column names. The '%' acts as a delimiter and is not part of the column name. 

 
 The adapter can be configured and used within a webAF project. Add a
 com.sas.storage.jdbc.JDBCConnection component to your project. Open the customizer and
 specify the values needed for your JDBC connection.These include driver name and URL. 
 Now open the customizer for the adapter. 
 Specify the value for JDBC Connection using the top combo box. The drop-down list
 will show all JDBC Connection objects that exist in your project.  
 You can set the properties for query statement, autoCommit, and read-only, as well.
