Data query method and system, heterogeneous acceleration platform, and storage medium

A data query system, applied to a heterogeneous acceleration platform comprising a CPU and a parallel processor, wherein the data query system comprises a memory storing a computer program that, when executed, causes the CPU and the parallel processor to implementing operations of:

• determining operators in a database management system, and accomplishing, in the parallel processor, roles of functions corresponding to the operators;
• in response to a SQL query statement being received, converting, by the CPU, a where clause in the SQL query statement into a data structure comprising a binary tree and a linked list, wherein each node in the data structure corresponds to one operator in the where clause;
• controlling the CPU to generate, based on node information, an operation code stream of the data structure, wherein the node information comprises a node position and a corresponding function name of each node in the data structure;
• and
• performing, by the parallel processor, a screening operation corresponding to the operation code stream on records in the database management system to obtain a query result conforming to the where clause.

A non-transient storage medium storing computer-executable instructions that, when loaded and executed by a processor, perform operations of:

• determining operators in a database management system, and accomplishing, in a parallel processor, roles of functions corresponding to the operators;
• in response to a SQL query statement being received, converting, by a CPU, a where clause in the SQL query statement into a data structure comprising a binary tree and a linked list, wherein each node in the data structure corresponds to one operator in the where clause;
• controlling the CPU to generate an operation code stream of the data structure according to node information, wherein the node information comprises a node position and a corresponding function name of each node in the data structure;
• and
• performing, by the parallel processor, a screening operation corresponding to the operation code stream on records in the database management system to obtain a query result conforming to the where clause.
