Query properties tab: BPEL process editor
This topic includes a description of each of the fields on the Query properties tab of the Properties view.
Use the fields on this page to declare one or more query properties for the selected process variable. These query properties determine which parts of a variable can be queried in the runtime environment. At run time use the query API function to include a query property in a query. You can also use query tables to expose the query properties to the business user in Business Space. The query property may be either a built-in XML schema simple type, or a user-defined simple type based on a built-in XML schema type using restrictions. Complex types, list, and union types (neither built-in nor user-defined) are not supported for query properties.
Use the Add, Edit and Remove buttons to manage your query properties. When you Add or Edit a query property for an interface typed variable you will be presented with two choices:
- A local query property is created by selecting "From query" and can be used for getting and filtering data from a single process.
- A global query property is created by selecting "From property" and can be used when you would like to filter data from multiple processes. This option is only available when you have an interface typed variable, and a correlation property is defined for the underlying WSDL message. Since this correlation property can be shared between multiple processes, you must then define a query property "From property" in the corresponding interface typed variable for each process.
For data typed variables you can only define local query properties.
When you declare a query property a new entry is added to the table in the Query Properties tab. In general the fields of this table cannot be edited directly, to modify a query property click the Edit button. However, for certain query properties you can enter an XPath expression in the Query field directly, click the 
icon in the right side of the Query field, to load an XPath expression editor.
See Declaring a query property for a variable. Also see the runtime example on Including query properties in a query or Including query properties in a query if you have IBM Process Server installed.
For more information on using query tables to expose query properties see 
Query tables in Business Process Choreographer or Query tables in Business Process Choreographer if you have IBM Process Server installed.
If these link fails, you need to install additional documentation. In IBM Integration Designer, open the Resource perspective if you are not already there (click Window > Open Perspective > Other > Resource). Then, in the main menu, click Help > Software Updates. In the Software Updates and Add-ons window, select the Available Software tab. Click Add Site and specify the following location: http://publib.boulder.ibm.com/dmndhelp/downloads/v6r2mx/wid/. Expand the results under this repository location, select the documentation that you want, and click Install. You will need to restart IBM Integration Designer to see the additional documentation.
