Abstract
In accordance with an embodiment, described herein is a system and method for dynamically converting data manipulation language (DML) code embedded in a mainframe application rehosted in a mainframe rehosting platform. The DML code can include SQL scripts with SQL statements, and standalone SQL statements for accessing a source database in a mainframe computer. The DML code can be converted programmatically and immediately before the DML code is to be executed during the execution of the rehosted mainframe application. A database access script converter in an application runtime of the mainframe rehosting platform can load a database schema of a target database and a set of conversion rules, parse the rehosted mainframe application to identify the DML code, and convert each SQL statement based on one or more conversion rules and the database schema, for execution against the target database.
