Parameters
hRecord
-
Return value
hHash
This method allows you to set all elements of a hash retrieved through the Record method that have not been modified to null, keeping their initial value. It is only used for INSERT and UPDATE operations in which user editing has been allowed and you want all fields not modified by the user to return to null values, thus preventing them from being included in a potential SQL insert or update statements created with SqlInsert or SqlUpdate .
