This disclosure relates generally to a method and system for extraction of SQL queries in an application. Various conventional approaches models SQL query extraction at a specific program point problem as an instance of string expression problem. Many string analysis based solutions are not scalable for large applications and those which are scalable do not account explicitly for the heap based flow. In an embodiment, the disclosed method and system utilizes a multi-criteria slicing based model which takes into account the data flowing through heap and contributing to SQL queries generation.
