[Return code] JET_errKeyIsMade [Description] 
The column data provided to JetMakeKey was rejected because column data has already been provided for all the key columns in the current index. This can happen in three ways. The first way is if column data is provided for each key column in the current index. The second way is if column data has been provided for at least one key column and a wildcard option was chosen for the last call. The third way is if a previously constructed search key was provided using JET_bitNormalizedKey, which covers all key columns.
