多表联合查询方法、装置、设备及存储介质
By parsing the query statement to generate a directed acyclic graph, the query order of the data tables is automatically determined, which solves the cumbersome and error risk of multi-table joint queries in the existing technology and realizes efficient and accurate data query.

AI Technical Summary
In scenarios where data source queries are limited, existing technologies require developers to manually design logical execution plans for multi-table join queries, which is tedious, error-prone, and makes it difficult to effectively avoid duplicate queries and data redundancy.
By parsing the query statement, a directed acyclic graph is generated, which automatically determines the query order of the data tables and automatically generates a logical execution plan, ensuring that the queries are executed in the correct order and avoiding dependency issues between data tables.
It improves the efficiency and accuracy of multi-table join queries, reduces the workload of developers and human error, and ensures the completeness and accuracy of query results.
