CalculatedDefaultValue (Property)
In french: ValeurParDéfautCalculée

From version 26, CalculatedDefaultItem is kept for backward compatibility. This property is replaced by CalculatedDefaultValue.
The CalculatedDefaultValue property is used to:
  • Finding out the SQL expression defining the default value of an item. This item was defined in the data model editor or through programming.
  • Define the SQL expression that returns the default value of an item (item described through programming only).
Example
AFile is File Description
AnItem is Item Description
AnItem.Name = "CmdDate"
AnItem.Type = hItemDateTime
AnItem.CalculatedDefaultValue = "SYSDATE"
HDescribeItem(AFile, AnItem)
