Graphical Query Designer User Interface • • 6 minutes to read • Contributors • • • • In this article Reporting Services provides both a graphical query designer and a text-based query designer for creating queries to retrieve data from a relational database for a report dataset in Report Designer. Use the graphical query designer to interactively build a query and view the results for data source types SQL Server, Oracle, OLE DB, and ODBC. Use the text-based query designer to specify multiple Transact-SQL statements, complex query or command syntax, and expression-based queries. For more information, see. For more information about working with specific data source types, see.. Graphical Query Designer This graphical query designer supports three types of query commands: Text, StoredProcedure, or TableDirect.
Before you create a query for your dataset, you must select a command type option on the Query page of the dialog box. The following options are available for query type: • Text Supports standard Transact-SQL query text for relational database data sources, including data processing extensions for Microsoft SQL Server and Oracle. • TableDirect Selects all the columns from the specified table. For example, for a table named Customers, this is the equivalent of the Transact-SQL statement SELECT * FROM Customers. • StoredProcedure Supports calls to stored procedures on the data source. To use this option, you must have been granted Execute permissions on the stored procedure by the database administrator on the data source.
The default command type is Text. Note Not all data processing extensions support all types.

The underlying data provider must support a command type before the option is available. Command Type Text In Text type, the graphical query designer presents four areas, or panes.
You can specify columns, aliases, sort values, and filter values for a Transact-SQL query. You can view the query text generated from your selections, run the query, and view the result set. The following figure shows the four panes. The following table describes the function of each pane.
Pane Function Diagram Displays graphic representations of the tables in the query. Use this pane to select fields and define relationships between tables. Grid Displays a list of fields returned by the query. Use this pane to define aliases, sort order, filters, groups, and parameters. SQL Displays the Transact-SQL query represented by the diagram and Grid panes. Use this pane to write or update a query using Transact-SQL.
Result Displays the results of the query. To run the query, right-click in any pane, and then click Run, or click the Run button on the toolbar. When you change information in any one of the first three panes, those changes will appear in the other panes. For example, if you add a table in the Diagram pane, it will automatically be added to the Transact-SQL query in the SQL pane. Adding a field to the query in the SQL pane will automatically add the field to the list in the Grid pane and update the table in the Diagram pane. For more information, see. Toolbar for the Graphical Query Designer The graphical query designer toolbar provides buttons to help you design Transact-SQL queries using the graphical interface.
