The Query Designer allows you to use a simple graphical interface to construct SQL queries. The fields selected in the Output column are added to the SELECT clause.
To switch between the tables, use the Tables list panel on the left.
This feature allows you to limit the number of records to be displayed on the List, Print, Export, Details pages. It can be useful if you need to speed up the loading of the webpage; or when your chart has too many items in it, and you need to show only the most significant ones. It also works with the List pages added to the Dashboard.
The search and filters are applied first, and then the results are limited to first "N" rows.
This option works with all ASPRunner.NET project items except with the reports that have group fields selected.
When you connect to databases like DB2, Oracle or PostgreSQL, and your SQL query contains aliases, we recommend to enclose them in double-quotes. Here is an example:
If the field was assigned an alias in the SQL query, then the values array gets the alias instead of the field name from the database. E.g., if you have an SQL query SELECT salesrep_id AS Inv_Salesrep ..., you should use values("Inv_Salesrep").
To add a join, click the Add Table button, select the table, and then drag-n-drop the fields from the first table to the joined table.
To set up the join clause type, double-click on the line between the tables, select the link fields in the Table link properties dialog for both tables, and choose the join type.
To add calculated fields, use the empty cells below the field names:
In the example above, the alias Discount is assigned to the calculated field Price*0.1.
You can add a WHERE clause in the Filter column. If you need to add two or more conditions, use the Or... columns.
For more complicated queries, wrap the condition with parentheses:
If you'd like to specify the default sorting order on the List page (ascending or descending), select the Sort Type in the corresponding column for the necessary fields.
To add a GROUP BY clause, click the Group By button and select one of grouping function in the Group By column.

Here is how you can create a query in MS Access (other database types provide similar options):
1. Run MS Access and create a new query. Switch to SQL view.
2. Insert your SQL query there.
3. Save this query as qryNewQuery.
4. Run ASPRunner.NET and use qryNewQuery as a datasource table.
