Problems solved by technology

[0008] However, as mentioned above, since a binding parameter is converted into a data manipulation language to be processed in the conventional platform-dependent model compiler, there is a problem of increasing the parsing overhead of structured query language, and as Since the processing is performed in a single data manipulation language, it is difficult to expect to improve the performance of the platform-dependent model compiler

Abstract

A PSM complier optimizer analyzes a pattern of the PSM program to generate instruction codes, which will be subjected to a bulk operation and makes the instruction codes for the bulk operation in a form of an array of bind parameters to perform a bulk cursor. Accordingly, the bulk DML processing improves the performance of the PSM program.

Description

technical field [0001] The present invention relates to a platform-specific models (PSM, Platform-specific models) compiler (compiler), especially in the aspect of optimizing the platform-specific model compiler, which can be generated through batch operation ( bulk operation) to convert the instruction code, make the bound parameter (bind parameter) into an array (array) for the generated bulk operation code, and execute the bulk cursor (bulk cursor) to enable batch data manipulation Language (Data Manipulation Language) processing, thereby improving the performance of the program, a platform-dependent model compiler optimization device and method capable of batch data manipulation language (DML) processing. [0002] This invention was derived from research carried out as part of the Industrial Convergence Source Technology Development Project of the Ministry of Knowledge Economy (10040937, Development of Integrated Solutions for Japanese Mainframe Computers (Hitachi, Fujitsu...
