IBM Lotus Domino Designer 8.5
  Versionen 8.5 und 8.5.1

Examples: @IsError

1. This example returns 1.

@IsError(1/0)

2. This example returns 0.

@IsError(1/2)

3. This formula checks to see if there is an @ERROR in the Price field, and returns "There is an error in the price field" if it encounters an error; otherwise it returns 0.

@If(@IsError(Price); 

   @Failure("There is an error in the price field"); @Success)

4. This agent tests the return value of an @DbLookup statement for an error. If the @DbLookup statement causes an error, the agent returns the text "Not available."

FIELD Phone := @DbLookup(""; "Snapper" : "names.nsf"; "People";

@Right(Name; " ") + " , " + @Left(Name; " "); "OfficePhoneNumber");

@If(@IsError(Phone);"Not available")
