Im am trying to perform an update query on a table that contains 2 Primary Keys but when i try and call the query i get the following message:

Cant update all the records in the Update Query.

Tivoli Fixes didnt update 0 field(s) due to a type conversion failure, 20 record(s) due to key violations, 0 record(s) due to lock violations and 0 record(s) due to validation rule violations.

i looked in the help - and it suggests that within the code i can use the Primary Proerty and change the primary keys to non-primary while i perform the update query and then set them back. Please could you help me  on how i would do this?

Normally you won't use an update query to change the primekey (or keys) of a table.
To change those you would use an Append (INSERT INTO) query followed by a DELETE.
A primekey identifies a row. Changing it implies effectively adding a new one and removing the old one.
Clear sofar ?

What is it exactly that you're trying to achieve?

Key violations are the result of one of two things:

1. Duplicate key on an index that doesn't allow duplicates (i.e. the primary key).

2. You have a relationship (M-O) with another table and their is no corresponding parent record in that table.
