windows application - updating database
Hi there !
When I'm trying to update an existing row in a table,
i recieve the following error :
An unhandled exception of type 'System.Data.ConstraintException'
occurred in system.data.dll
Additional information: Column 'StudentID, CourseID, Type' is
constrained to be unique. Value '1234567, course 06, master'
is already present.
I use sql server 2000.
Does anyone Knows how to fix the problem ?
