Method and system for transactional fingerprinting in a database system

摘要

Transactions with respect to database operations are fingerprinted by associating transaction identifiers with logged information about those database operations. An SQL query is obtained prior to its evaluation by a database engine. A transaction identifier to be associated with the SQL query is also obtained. The SQL query is then modified to generate a modified SQL query, wherein the modified SQL query includes a WHERE clause that contains an expression that always evaluates to a logical true value, and wherein the expression contains the transaction identifier. The modified SQL query is then sent to the database engine for evaluation within the data processing system. When the processing of the modified SQL query is logged with a copy of the modified SQL query, the logged information contains a copy of the transaction identifier.
