Error description

  • MS Sql Server uses two sort orders with the collation
    SQL_Latin1_General_CP1, one for Unicode data, and other for
    non-Unicode data.  UDA custom collation SQL_Latin1_General_CP1
    is defined for non-Unincode data only, but UDA applied collation
    SQL_Latin1_General_CP1  for both char, and nchar columns.  A
    local join produced in-correct results when one leg of the join
    is sorted locally, and other leg of the join is sorted by MS Sql
    Server.
