Abstract: A method, computer program product, and system include a processor(s) obtaining a query request from an application via a source database management system to a target database management system, where the query request comprises a query and a query timestamp indicating a last update to table(s) in the source database management system referenced in the query request. The processor(s) determines a table update timestamp indicating a last time when the table(s) in the source database management system referenced in the query request was replicated to the target database management system. The processor(s) generates an indicator where the indicator represent a difference between the query timestamp and the table update timestamp. The processor(s) executes the query in the target database management system. The processor(s) transmit a query result and the indicator to the source database management system.

Abstract: A method for processing an unsupported data type in a database is disclosed. The method for processing an unsupported data type in a database comprises detecting, while copying data from a primary to a secondary database, a table for data comprising a data type that is unsupported by the secondary database. Furthermore, the method comprises generating a base table in the secondary database as a copy of the detected table of the primary database without the data of the unsupported data type, generating an additional table in the secondary database for data of the unsupported data type, and linking the additional table to the base table in the secondary database via a row-identifier relationship. Additionally, the method comprises accessing data of the unsupported data type via the additional table while performing queries against the secondary database.
