Patent number: 11941142Abstract: Methods for using SQL statements to access an application-server-managed database are disclosed herein. In some embodiments, a user sends, either directly or indirectly (i.e., remotely) a SQL statement from an ODBC application or server, respectively, to an application server that preprocesses SQL statements for accessing data from a centralized database. The application server may have a SQL endpoint, and access to the SQL endpoint may be determined by a user's logon credentials, a user's presentation of a SAML token, or a user's presentation of a valid certificate. The application server may then parse the SQL statement and determine the user's authorization to access certain objects in the centralized database based on a SQL handler design-time configuration. A result from the statement may be sent back to the user either directly or indirectly and exposed.Type: GrantFiled: July 30, 2021Date of Patent: March 26, 2024Assignee: SAP SEInventors: Arne Harren, Marco Haupt, Helmut Prestel, Rolf Hammer, Christiane Kettschau, Kai Baumgarten, Diego Sebastian Will, Minh-Khanh Do, Timm Falter, Frank-Martin Haas, Kilian Kilger

Patent number: 10652338Abstract: The present disclosure involves systems, software, and computer implemented methods for event processing in background services. One example method includes receiving a request to create a daemon session, the request including at least one parameter. The session is created, including storing the at least one parameter in a memory storage that is configured to survive a restart of the session. A set of messages is received for the session. The messages are stored in a queue that is configured to survive a restart of the session. A determination is made that the session is to be restarted. A restart of the session is initiated, including providing the at least one parameter to the session during the restart of the daemon session and providing unprocessed messages to the session after the session has been restarted, to enable the session to process the unprocessed messages.Type: GrantFiled: June 19, 2017Date of Patent: May 12, 2020Assignee: SAP SEInventors: Masoud Aghadavoodi Jolfaei, Frank Radmacher, Edgar Lott, Achim Braemer, Sasan Memar-Zahedani, Helmut Prestel

Patent number: 10061800Abstract: Disclosed herein are systems and methods for embedding database procedures in data-driven software applications written in a language different from the database-procedure language. For example, in some embodiments, the hosting application may be written in ABAP whereas the database procedure may be written in SQLScript. In various embodiments, the database procedures are encapsulated in specially marked methods of the host application, which, when called at runtime, cause the database procedures to be created in a database catalog and executed on a database server.Type: GrantFiled: November 20, 2014Date of Patent: August 28, 2018Assignee: SAP SEInventors: Martin Hartig, Helmut Prestel, Rolf Hammer, Kai Baumgarten, Sigrid Wortmann, Christiane Kettschau, Stefan Werner, Ralf Wendelgass

Patent number: 9753971Abstract: Disclosed herein are systems and methods for the hot deployment of database procedures embedded in a host software application. In various example embodiments, the database procedures are encapsulated in specially marked methods of the host application, which, when called at runtime, cause the database procedures, and associated procedure stubs through which the database procedures are called, to be created in a database catalog and executed on the database server. When an embedded database procedure is modified in an application by one user during execution of that application by a second user, compilation of the modified database procedure may result in deletion of the original database procedure and/or associated procedure stub from the database, avoiding inconsistencies between database procedure versions during application execution by the second user.Type: GrantFiled: November 20, 2014Date of Patent: September 5, 2017Assignee: SAP SEInventors: Martin Hartig, Helmut Prestel, Rolf Hammer, Kai Baumgarten, Sigrid Wortmann, Christiane Kettschau, Stefan Werner, Ralf Wendelgass
