摘要

The present invention is used when data is exchanged with a server process of a database system by using a main language variable or a descriptor area in an ESQL / C program as a client application program interface provided by a server / client relationship database management system To a method of transmitting data.;In the relational database management system, when the data is a numeric type 'date type' time interval type, it is converted into a character string by a DataToChar function, stored in a main language variable and a descriptor variable, and transmitted by an IPC (Information Processing Code) method And restoring the transferred character string by the CharToData function; The data is stored in the main language variable and the descriptor variable, and is delivered by the IPC method. Thus, it is possible to store the original language variable and the descriptor area in the relational database management system, Structure, and processing method, so that effective data transmission can be performed.
