Data fields

Intrexx data fields are equivalent to a column in the portal database. Data entered by users in Intrexx applications is saved in data fields that are linked to input elements. Data that has already been saved are displayed with view elements and input elements, but can only be edited with input elements.

Further information on application elements can be found here.

When creating a new element, a wizard will guide you. Here you can decide whether you also want to create a new data field with the new element, which is then automatically linked to the element. Click here for more information.

You also have the option of creating elements and data fields independently of each other and linking them together if required.

The data fields of a data group can be displayed via the main menu "Edit / Show data fields" or "Hide " or via the context menu of a data group in the application structure if the data group is selected.

In each data group you will already find the system data fields

  • (PK) (S) ID

    ID of the data record

  • (S) UserID

    ID of the user who last edited the data record

  • (S) ChangeDate

    Date of last change

  • (S) CreatorID

    ID of the user who created the data record

  • (S) CreationDate

    Date of last change

  • (S) ChangeDate

    Date of last change

These data fields can, if desired, be additionally connected to view elements. When creating a data set in the browser, system fields will automatically be filled with relevant data by Intrexx.

Information on data types and control types in Intrexx can be found here.

New data fields that are not automatically linked to elements can be created via the properties of a data group.

Create new data field

To create a new data field, select a data group in the application structure. Then select the context menu "New / Data field" or the main menu "New / Data field".

Title

The data field's title can be modified here. Click here for more information about this topic.

Data field name

The name of the data field can be changed here, provided the application has not been published yet. The prefix is updated when the data type (see below) is modified. The actual name is not modified. If the specified name does not possess a data type prefix, changing the data type will leave the name as it is. This means, for example, changing the data type from “string” to “datetime” would change the name from “STR_NAME” to “DT_NAME”, whereas “TEST_NAME” would not be changed.

Data type

Select the desired data type here.

File

This data type is used for the “File selection” element, for example.
