Abstract

The embodiment of the invention provides a database statement processing method and device, electronic equipment and a storage medium, relates to the field of cloud computing, and is applied to a non-coordination node in a relational database management system, and the relational database management system further comprises a coordination node and a plurality of working nodes. The method comprisesthe following steps: acquiring an operation request sent by a client in communication connection with a non-coordinated node; and when the operation request is judged to be the database mode definition language statement, sending the database mode definition language statement to the coordination node, so as to enable the coordination node to analyze the database mode definition language statement to generate a plurality of corresponding first sub-tasks, and sending each first sub-task to the corresponding working node. Therefore, the situation that the non-coordination node returns information prompting the user that the database mode definition language statement is not supported is avoided, the user is further prevented from resending the database mode definition language statement tothe coordination node, user operation is reduced, and the flexibility of the database management system is improved.

Description

technical field [0001] The present application relates to the field of databases, in particular to a database sentence processing method, device, electronic equipment and storage medium. Background technique [0002] With the development of network technology, more and more data are generated in the network. In order to perform subsequent analysis on the generated data, the data is usually stored in the database, and then the data in the database is added, deleted, modified, checked, etc. operate. In order to perform the above operations on the database more conveniently, it is necessary to horizontally expand the independent database. For example, Citus, as a horizontal expansion plug-in of a relational database management system, can realize the horizontal expansion of the database. Such as figure 1 As shown, it is a system diagram of a relational database management system using the citus plug-in, in figure 1 , may include one coordinating node 110 , at least one non-...
