Connecting a Schema Holder
As described previously, connection can take place automatically using the information that you enter when you create a schema holder. In addition, Progress provides the following techniques for connecting to a schema holder:
- Use the Progress Data Dictionary or Data Administration tool. From the main menu, select Database
Connect and supply the schema holder’s physical name and the appropriate connection parameters. You cannot use the Auto–Connect option to connect to an ODBC data source. You connect to the data source when you select it as your working database.
- Use the Progress 4GL CONNECT statement (see its reference entry in the Progress Language Reference). A CONNECT statement must first list the schema holder and related connection parameters, then the ODBC data source and related parameters.
For example, this command connects a schema holder named holder and an ODBC-supported data source named odbdemo:
You can use combinations of different connection techniques. For example, you can connect the schema holder at startup, then connect to the DataServer using the Progress CONNECT statement. Any combination of connection techniques works, as long as you follow these steps in the order shown:
If you connect to the schema holder and the ODBC data source in a single startup command or connection statement, be sure to specify parameters that affect the schema holder before the Database Name (-db) parameter. Specify only those parameters that affect the ODBC data source connection after the -db parameter.
The following section explains how to connect both a schema holder and an ODBC data source when you start up Progress.
