This article explains how to use the Formula Editor, and how you can group, summarize, and associate multiple report elements.
Use the Formula Editor
When adding conditional formatting or other constraints on data-driven report elements, you have the option of using a built-in Formula Editor to help you build an expression with a graphical interface. All element properties in Report Designer can have formulas. You can type in your own formula by hand, but it's much easier to use the built-in Formula Editor to build an expression.
The Formula Editor provides you with basic math and comparison operators so that you don't have to enter them manually. Also provided are concatenate and percent functions. Click the Field Selector to select fields in the report.
Follow the instructions below to use Formula Editor:
Click on the element you want to add a condition or constraint to.
In the Style pane, select the property you want to add a constraint to, then click the round green + icon on the right side of the field.
Click the ... button.The Formula Editor window appears.
Select a function category from the drop-down box.The default category is All.
Select a function from the Functions list.If you click on a function, a description of what it does will appear in the tan-colored field at the bottom of the window.
Double-click on a function to bring up the option fields.
Erase the default values in the option fields, and replace them with your own settings.If you need to associate a column with a function, click the Select Field button to the right of the field, then select the data or function you want to use. Follow proper SQL syntax in your options; all values must be in quotes, and all column names must be in uppercase letters and enclosed in square brackets.
When you're done, click OK, then click Close.
Formulas and functions
You can create commonly-used formulas and learn how to use functions.
Summarize data in groups
You can sort data in multiple fields by creating groups.
Perform the following steps to summarize data in groups:
Double-click on your data source to open the query configuration dialog.
Reorder your query so that the fields you want to sort by are listed at the beginning of your SELECT statement.If you use the SQL Query Designer to do this, you can simply drag and drop the columns in your SELECT section to change their order; if you use the query window, you can carefully copy and paste the columns to reorder them.
Copy the same columns you reordered in the SELECT section into the ORDER BY section, in the same order you specified previously.
SELECT `PRODUCTS`.`PRODUCTLINE`, `PRODUCTS`.`PRODUCTVENDOR`, `PRODUCTS`.`PRODUCTNAME`, `PRODUCTS`.`PRODUCTCODE`, `PRODUCTS`.`PRODUCTSCALE`, `PRODUCTS`.`PRODUCTSCALE`, `PRODUCTS`.`PRODUCTDESCRIPTION`, `PRODUCTS`.`QUANTITYINSTOCK`, `PRODUCTS`.`BUYPRICE`, `PRODUCTS`.`MSRP` FROM `PRODUCTS` ORDER BY `PRODUCTS`.`PRODUCTLINE` ASC, `PRODUCTS`.`PRODUCTVENDOR` ASC, `PRODUCTS`.`PRODUCTNAME` ASC
Save the query and close the configuration window.
Right-click the Groups category in the Structure pane, and select Add Group from the context menu.
Type in a name for this group in the Name field.
In the Available Fields area on the left, select each row you want to add to the group, then click the arrow button to move it to the Selected Fields area on the right.
Select the Data pane, then click Add Function.
Double-click the Sum function category, then select Sum, then click Add.
Select the newly created TotalGroupSumFunction item in the Functions list, then click on the Reset on Group Name property in the lower right pane.
Click the [...] button, select the group you just created in the list, then click OK.
