Abstract

One or more embodiments of the invention provide the ability to utilize the Java programming language as a stored procedure language. One or more embodiments of the invention provide for Java abstract data types (ADT) that map to ADT attributes from a database. The Java ADT can then be manipulated in an application written in the Java programming language such as a stored procedure. Each ADT attribute from a database is mapped to a Java class by wrapping the ADT definition (which is commonly written in C ++) in a Java wrapper. The wrapping process enables a user to write any client side Java application. Once the ADTs are wrapped and a stored procedure is created, the stored procedure must be able to execute. Enhancements permit a stored procedure written in the Java programming language to execute. Such enhancements include a server side cursor that the stored procedure can use to run SQL queries. Additionally, the server has been enhanced to link to a Java virtual machine that can be used to execute the bytecodes of the stored procedure written in the Java programming language.
