Property :: cursorEquals - Is property handle the same
The function compares the property handle cursors referenced in the property handles. When the cursors in both property handles are the same, the function returns true , false otherwise.
Property handles will share the cursor, when being created by assigning property handles or by calling use() . Property handles do not share the cursor, when being opened with cursorCopy () .
The cursor in the property handle may change for subordinated property handles, when the parent property handle is weak-typed or untyped. The cursor is updated before comparing.
The property throws an exception, when the calling property handle is not valid.
The value is true when the function was executed successfully. Otherwise the value is set to false .
