// Delete the current record from Customer file ResDelete = cdbDelete("MyDatabase", "Customer") // Has a problem occurred? IF ResDelete = False THEN Error(ErrorInfo())
// Standard "Contacts" database // Delete the current record from the Contacts file ResDelete = cdbDelete("", cdbContact) // Has a problem occurred? IF ResDelete = False THEN Error(ErrorInfo())
Syntax
<Result> = cdbDelete(<Database> , <Data file> [, <Record number>])
<Result>: Boolean - True if the function was successful,
- False otherwise. If an error occurs, you can get the details of the error with ErrorInfo.
<Database>: Character string (with quotes) - Name of database that was opened by cdbOpen,
- Empty string ("") to handle one of the standard databases of the Mobile Device (tasks, contacts, ...).
<Data file>: Character string (with quotes) or constant Data file to use. This parameter corresponds to:- the name of data file to use.

This number is returned by cdbRecNum. If this parameter is not specified, cdbDelete will handle the current record.Caution: The record numbers are not consecutive numbers.
