Abstract
Provided is a data query method, applied to a heterogeneous acceleration platform. The data query method includes: determining operators in a database management system, and accomplishing, in a parallel processor, functions corresponding to the operators (S101); if an SQL query statement is received, converting, by using a CPU, the where clause in the SQL query statement into a data structure including a binary tree and a linked list (S102); controlling the CPU to generate an operation code stream of the data structure according to node information (S103); and performing, by using 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 (S104).
