Abstract
Implementations of the present disclosure include methods, systems, and computer-readable storage mediums for upgrading applications. Actions include receiving an upgrading request for an original table of an application, generating an upgraded table including a structure matching the original table, setting a session variable to initiate an application upgrade, and adding a set of triggers to the original table to selectively control read operations and write operations for the original table and the upgraded table based on the session variable.
Claims20
A computer-implemented method for upgrading applications, the method being executed using one or more processors and comprising:
- receiving, by the one or more processors, an upgrading request for an original table of an application;
- generating, by the one or more processors, an upgraded table comprising a structure matching the original table;
- setting, by the one or more processors, a session variable to initiate an application upgrade;
- and
- adding, by the one or more processors, a set of triggers to the original table to selectively control read operations and write operations for the original table and the upgraded table based on the session variable.
A non-transitory computer-readable storage medium coupled to one or more processors and having instructions stored thereon which, when executed by the one or more processors, cause the one or more processors to perform operations for upgrading applications, the operations comprising:
- receiving an upgrading request for an original table of an application;
- generating an upgraded table comprising a structure matching the original table;
- setting a session variable to initiate an application upgrade;
- and
- adding a set of triggers to the original table to selectively control read operations and write operations for the original table and the upgraded table based on the session variable.
A computer-implemented system for upgrading applications, the system comprising:
- a client-side computing device;
- and
- a computer-readable storage device coupled to the client-side computing device and having instructions stored thereon which, when executed by the client-side computing device, cause the client-side computing device to perform operations for upgrading applications, the operations comprising:
- receiving an upgrading request for an original table of an application;
- generating an upgraded table comprising a structure matching the original table;
- setting a session variable to initiate an application upgrade;
- and
- adding a set of triggers to the original table to selectively control read operations and write operations for the original table and the upgraded table based on the session variable.
