LISTOFFIELDS ER function

  • Άρθρο

The LISTOFFIELDS function returns a Record list value that is created based on the structure of the specified argument of the Enumeration or Container (record) type.

Syntax 1

LISTOFFIELDS (path)

Syntax 2

LISTOFFIELDS (path, language)

Arguments

path: Data source reference

The valid reference path of a data source of one of the following data types:

  • Model enumeration
  • Format enumeration
  • Application enumeration
  • Container (record)

language: String

Text that represents a language code.

Return values

Record list

The resulting list of records.

Usage notes

The list that is created consists of records that have the following fields:

  • Name (String data type)
  • Label (String data type)
  • Description (String data type)
  • IsTranslated (Boolean data type)

If the path argument refers to a data source of the Container (Record) type, for every field of the referenced container record, a new record is added to the list that is created. For every record that is created, the Name field returns the name of the field of the referenced container record that the current record was created for.

If the path argument refers to a data source of one of the Enumeration types, for every enumeration value of the referenced enumeration, a new record is added to the list that is created. For every record that is created, the Name field returns the value of the referenced enumeration that the current record was created for, the Description field returns the description of that enumeration, and the Label field returns the label of that enumeration.

At runtime, when syntax 1 is used, the Label and Description fields must return values that are based on the language settings of the Electronic reporting (ER) format that is running:

  • If the labels and descriptions for the requested language are available, the Label and Description fields return values that are based on that language, and the IsTranslated field returns True.
  • If the labels and descriptions for the requested language aren't available, the Label and Description fields return values that are based on the default EN-US language, and the IsTranslated field returns False.

At runtime, when syntax 2 is used, the Label and Description fields must return values that are based on the language that is defined as the second argument of the called function:

  • If the labels and descriptions for the requested language are available, the Label and Description fields return values that are based on that language, and the IsTranslated field returns True.
  • If the labels and descriptions for the requested language aren't available, the Label and Description fields return values that are based on the EN-US language, and the IsTranslated field returns False.

Example 1

In the following illustration, an enumeration is introduced in an ER data model.

Enumeration in a model

The following illustration shows these details:

  • The model enumeration is inserted into a report as a data source.
  • An ER expression uses the model enumeration as a parameter of the LISTOFFIELDS function.
  • A data source of the Record list type is inserted into a report by using the ER expression that is created.

Format

The following example shows the ER format elements that are bound to the data source of the Record list type that was created by using the LISTOFFIELDS function.

Format design

The following illustration shows the result when the designed format is run.

Format output

Note

Based on the language settings of the parent FILE and FOLDER format elements, translated text for labels and descriptions is entered in the output of the ER format.

Example 2

You use the Calculated field data source type to configure enumType_de and enumType_deCH data sources for the enumType data model enumeration:

  • enumType_de = LISTOFFIELDS (enumType, "de")
  • enumType_deCH = LISTOFFIELDS (enumType, "de-CH")

In this case, you can use the following expression to get the label of the enumeration value in Swiss German, if that translation is available. If the Swiss German translation isn't available, the label is in German.

IF (NOT (enumType_deCH.IsTranslated), enumType_de.Label, enumType_deCH.Label)
