Claim 2:
3. The data query method according to claim 2, wherein the performing, by the parallel processor, the screening operation corresponding to the operation code stream by using each of the target records as an argument source to obtain a Boolean value corresponding to each of the target records comprises:
reading a current operation code from the operation code stream;
determining an operation code type of the current operation code;
in response to the current operation code being an arithmetic operation code, reading target arguments corresponding to the current operation code from the argument source, and performing an arithmetic operation of a function corresponding to the current operation code on the target arguments to obtain an operation result, wherein the argument source comprises the target record, a preset constant, and a data stack, and the data stack is configured to store the operation result of the arithmetic operation code and a logical operation code in the operation code stream;
in response to the current operation code being the logical operation code, reading a Boolean-type operation result from the data stack, and performing a logical operation corresponding to the logical operation code on the Boolean-type operation result to obtain an operation result;
storing the operation result to the data stack;
determining whether all the operation codes in the operation code stream have been read;
in response to all the operation codes in the operation code stream having been read, taking the operation result obtained from a latest logical operation as the Boolean value corresponding to the target record; and
in response to not all the operation codes in the operation code stream having been read, performing an operation of reading a current operation code from the operation code stream.
