Custom Query

Your model contains a great deal of information on both project design and project management, and a major benefit of the Chart feature is providing the facility to search through your model and extract specific aspects of that information using your own SQL Query, within the Chart element.

Extract Information Using SQL Query

Type in your SQL Query. The field provides the facilities of the Common Code Editor, such as intelli-sense.

The Select statement must include the alias 'Series'. For Heat Maps and Bar Charts you also have the option of grouping the results using the alias 'GroupName'. For example:

     Select t_object.Status AS Series, t_object.Author AS GroupName from t_object

Using SQL, you can also use the 'ChartValue' alias to reflect the actual value of an instance, as captured in a Tagged Value. With the dialog fields, two instances of a property such as Cost have an equal value of 1, whereas the SQL can capture the value of Cost being, say, 6 and 1 and so represent the first instance with a Heat Map cell that is 6 times larger than the second. This is an example of such a SQL statement:

     select t_object.Name AS Series, Packages.Name AS GroupName, aColor.[Value] AS Color, aSize.[Value] AS ChartValue from t_object, t_package

     RootPackage, t_package Packages, t_objectproperties aColor, t_objectproperties aSize

This statement can also be used for Bar Charts, except that the 'Color' alias is ignored; the 'Color' alias applies only to Heat Maps.

Additionally, you can also use #<macro>#s as string replacers in any WHERE statements in your query, as for other SQL Search Queries.
