To specify a different ordering, click the ORDER BY button.Here you can choose what columns the data should be sorted by, and if it should be sorted in ascending or descending order.(True, you have to provide a connection string rather than simply the path to the file, but Visual Studio 2005 can automatically create appropriate connection strings for those databases residing in your folder.) In this article we'll examine the Sql Data Source in detail, just touching upon the one difference in the Access Data Source.
If not, you have to find each and every page that references the connection string and update it accordingly.
Furthermore, by placing your connection string information in The Access Data Source differs from the Sql Data Source in one minor aspect - rather than specifying a connection string as with the Sql Data Source, the Access Data Source prompts for the path to the database file.
Therefore, the screen shots above are different for the Access Data Source.
Specifically, the first screen shot examined prompts for a file location; since there is no connection string, the second screen shot does not appear in the Access Data Source.
The selections here tack on an If you opt to select the columns to return from a table or view you can only configure simple queries that involve a single table or view.
With relational databases, often there's data in related tables that we need to grab, requiring s.With the declarative, "code free" Data Source controls you can create a page that displays database data in under 15 seconds and without having to write a line of code. Both controls have virtually the same featureset, the only difference being how you specify the connection information.In fact, the Access Data Source control is really superfluous since Microsoft Access databases can be accessed through the Sql Data Source control just as easily.Here you can see that I'm returning the By default the data is returned in the order the database stores the records.If there's a clustered index (such as a primary key constraint) on the table, the data will be ordered by the column(s) that make up that index; otherwise, the data is ordered by order it was entered into the database table.While you can set all of these properties by hand in the Source view, the Design view offers a time-saving wizard for quickly specifying which database to connect to and what query to issue.
