DATA ACCESS METHOD AND APPARATUS FOR DATABASE, AND DEVICE

A data access method and apparatus for a database, and a device. The present application is applicable to a scenario where a client initiates a data access instruction for different databases. An instruction execution apparatus acquires a first execution plan, wherein the first execution plan is generated on the basis of a data access instruction initiated in any database; and the instruction execution apparatus generates a second execution plan according to the first execution plan, and then accesses data in the database on the basis of the second execution plan. The instruction execution apparatus can process first execution plans from different databases, is adapted to different databases, and has a relatively high matching degree. The instruction execution apparatus executes a data access operation, which can also effectively improve the data access efficiency. La présente invention porte sur un procédé et un appareil d'accès aux données pour une base de données, et sur un dispositif. La présente inventio
