Abstract

Disclosed is a method of minimizing the performance and maintenance costs of supporting Double-Byte Character Set (DBCS) data and SQL extensions in a relational database's SQL processor. To maximize performance, a separate version of some key pieces of code are created to efficiently process DBCS data. To minimize maintenance, this dual- version approach is used with a very limited amount of code.
