    Question

    How do I see the available built-in and Ex Libris-added Prepackaged Access Reports (PpR) functions?

    Answer

    An expression, or calculated field, takes the values of one or more fields and uses them to create new values.  String functions (or just "functions") allow you to create expressions that manipulate text in a variety of ways.  For example, you may want to take just part of a field, or change a field to upper case.

    There are both built-in functions that come with Microsoft Access, and functions added to the PpR Reports.MDB file by Ex Libris.

    These functions can be viewed in Access Expression Builder.

    Expression Builder is available when creating or editing reports or queries.

    When editing a query, open the Expression Builder dialog box by selecting the query in design view, then placing your cursor in one of the fields, right-clicking and selecting Build from the menu.

    Once you are in the Expression Builder dialog box, you can display the list of available built-in and added functions.

    For example:

    expressionBuilder.jpg

    Under "Functions" you'll see the "Built-In Functions" that come with Microsoft Access, and below that a "Reports" functions element that includes the Ex Libris-added functions.

    You can display a list of the available functions by clicking on the appropriate Expression Element and then Expression Category.  

    Note that the name of added Expression Element will be the filename of your Reports.MDB file.  In the above example the filename is Reports-support-server.MDB (most customers' files will simply be Reports.MDB).

    Having trouble seeing a long BLOB function or other lengthy expression?  Put your cursor in the cell you want to view and hit Shift-F2.  This opens the contents of the cell in an Access zoom box.

    Additional Information

    See the Reporter User's Guide, Chapter 7, "Using the Expression Builder."

    • Left(CALLNUM,3)
    • Left(“004.12 A324d”,3) = “004”

    Right: Right part of text

    • Right(CALLNUM,3)
    • Right(“004.12 A324d”,3) = “24d”

    Mid: Part of text

    • Mid(CALLNUM,5,4)
    • Mid(“004.12 A324d”,5,4) = “12 A”

    Mid: Remainder of text

    • Mid(CALLNUM,5)
    • Mid(“004.12 A324d”,5) = “12 A324d”

    Date: Current date

    • Date()
    • Date() = #7/26/2021#

    CCur: Convert to currency

    • CCur(AMOUNT)
