The dbExpress component’s family provides four different dataset components: As you can see by comparing the two listings, this is a subset of the parameters of the driver. The ‘XE’ entry was also provided in my second post, above. Once you have defined the connection name, you can identify a database connection by simply setting the ConnectionName property to a valid connection name. I found it under Well take a look at all types of books and book-delivery systems.

Values property to assign values to individual parameters. Once LibraryName and VendorLib have been set, your application does not need to rely on dbxdrivers.
Each connection relates to the driver for its key attributes, as indicated by the DriverName property. As an alternative, you can start by selecting directly the ConnectionName property, which in this case includes the entire list.
In fact, when you select a driver or a connection at design time, the values of these files are copied to corresponding properties of the SQLConnection component, as in this example:.
Of course this is also the option you’ll want to use for unattended connections, for example on a Web server. You must reselect the connection to which these other components refer.

The ‘XE’ entry was also provided in my second post, above. If you read the entire drivers.
Driver and vendor libraries are listed in properties you can freely change at design time although you’ll rarely want to do thiswhile the database and other database-specific connection settings are specified in the Params properties.
This list resembles the aliases of the BDE, and you can enter multiple connection details for every database driver. When you select a driver or a connection at design time, the values of these files are copied to corresponding properties of the SQLConnection component, as in this example: Below, you will find the results of tnsping.
The dbExpress component’s family provides four different dataset components: Oracle 10g XE 2 Version: What really matters for the SQLConnection component is the value of its properties.
Setting it to False allows you to provide a password among the component settings and skip the login request dialog box, both at design time and at run time.
You can use this dialog to indicate the connection to use by selecting a driver and connection name. These components include a database connection component, a few dataset components a generic one; three specific versions for tables, queries, and delpbi procedures; and one encapsulating a ClientDataSet componentand a monitor utility. For each driver, there is a set of default connection parameters.
In practice, you could set up a SQLConnection component by setting up the driver and then assigning the database name directly in the Params property, forgetting about the predefined connection. There are two ways to do this:.

Because this dialog refers to ‘ Personal tools Log in. I’m not suggesting this as the best option, but it is certainly a possibility; the predefined connections are handy, but when the data changes, you still have to manually refresh every SQLConnection component. Instead of hooking up an existing connection, you can define a new one or see the details of the existing connections by double-clicking the SQLConnection component and launching the dbExpress Connection Editor Figure The connection component uses the information available in the drivers.
The connection component uses the information available in the drivers. The name of each combination is called a connection name. For Dynalink drivers, the driver name is associated with these files:. Please delph to reinstall your Oracle client or install another Oracle client.
