| When technology complements business | Copyright © 1987-2010 SimoTime Enterprises All Rights Reserved |
This example uses embedded SQL in a COBOL program to INSERT rows into a table of a relational data base. This example will read a VSAM, Keyed-Sequential-Data-Set (KSDS) to obtain the data that will be loaded into the table. In the world of programming there are many ways to solve a problem. This suite of programs is provided as a COBOL programming example of one of the possible solutions.
The following is the Windows Command file (ITQIN1E1.CMD) that is required to run as a job on a PC using Micro Focus Net Express.

The hexadecimal dump of the parameter-buffer uses the same technique as describe in another SimoTime example that describes the dumping of a data string using COBOL. The name of the member that does the actual hexadecimal dump is called SimoDUMP. A copy file (PASSDUMP.CPY) is provided for defining the pass area.
The SimoZAPS Utility Program has the capability of generating a COBOL program that will do the conversion of sequential and VSAM (KSDS) files between EBCDIC and ASCII. SimoZAPS can also read a sequential file in EBCDIC format and create an ASCII/CRLF file or VSAM KSDS file in ASCII format. The conversion tables may be viewed or modified to meet unique requirements. The Hexcess/2 function provides the capability of viewing, finding or patching the contents of a file in hexadecimal.
This item will provide a link to an ASCII or EBCDIC translation table. A column for decimal, hexadecimal and binary is also included.
Check out The VSAM - QSAM Connection for more examples of mainframe VSAM and QSAM accessing techniques with sample code.
This document provides a quick summary of the File Status Key for VSAM data sets and QSAM files.
Check out The SQL Connection for more examples of mainframe Relational Data Base management and accessing techniques with sample code.
The example for Create a Table uses embedded SQL in a COBOL program to create a data base for the item information.
The example for Update Table Information uses embedded SQL in a COBOL program to update data in an existing row or insert data into a new row using a unique primary key.
The example for Sequential Processing uses embedded SQL in a COBOL program to insert data into a table of an existing data base.
The example for Delete a Table uses embedded SQL in a COBOL program to delete a data base for the item information.
