Using the Query Builder

Using the Query Builder

Select from the Part, Variables, Functions, and Operators pick lists to create a query in the Query text box. Select an expression language to use for the current expression.
A copy operation in an assign activity can contain an XPath (or other selected language) query attribute that results in a string, number, or Boolean. The value of the query attribute is a query string that identifies a single value within a source or target variable part.
The Query Builder dialog is similar to the Expression Builder dialog, with the addition of a Variable Part tree for easy selection of parts.
For details on XPath syntax, see the XPath specification at
http://www.w3.org/TR/xpath.
To build a query:
  1. In the Properties view for an assign activity, select Copy operations.
  2. In the Copy Operations dialog, select Variable from the Type field.
  3. If desired, for easier query building, select a Part.
  4. Click
    Query Builder
    .
  5. If needed, select the
    Dialog (...) Button
    in the Query Language field to select a different query language URI that non-Process Developer engines support. Do the following:
    • In the Query Language dialog (or in the Properties view of the BPEL process), type in a different URI for a non-Process Developer configured language. The URI is ignored by Process Developer.
    • To restore the default, clear the URI and click
      OK
      .
  6. Select the variable parts, functions and operators from the boxes to build a query, following these tips:
    • For a shortcut, use content assist, as described in Using Content Assist
    • Select a variable, part, function, or operator and select
      Insert
    • Double-click a variable part to generate the location information for the query
    • Double-click a variable to paste the
      $
      variableReference
      function into the Query box
    • Double-click on a branch under a part to paste the location into the Query box
    • Add custom functions, as described in Process Developer Custom Functions
    • Add your own custom functions, as described in Creating POJO and XQuery Custom Functions
  7. Select
    Evaluate
    to substitute a sample value for a variable part and simplify the expression to view its value.
