Customer Table, COBOL & EXEC SQL
|
Update/Insert a Row Customer Table, COBOL & EXEC SQL | |
| The SimoTime Home Page |
Introduction
This example uses embedded SQL in a COBOL program to update a row within a table. This example sequentially reads the records in a VSAM, Keyed-Sequential-Data-Set (KSDS) and uses the information to update the relational data base. If an existing row with a matching primary key cannot be selected then a new row will be inserted. 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.
We have made a significant effort to ensure the documents and software technologies are correct and accurate. We reserve the right to make changes without notice at any time. The function delivered in this version is based upon the enhancement requests from a specific group of users. The intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources.

Programming Requirements
This suite of samples programs will run on the following platforms.
| ||||||||||
| Systems that support the execution of the Sample Program |
Programming Overview
The following diagram is an overview of how the demonstration program fits into the example.
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Read a KSDS and update existing or insert new rows into a Relational Data Base Table |
The main program (CUQUP1C1) will read an Indexed file (CUSTMAST) and use this information to update an existing row in a relational data base table (CUSTRDB1). If a row with a matching key does not exist then a new row will be inserted.

Company Overview
SimoTime Technologies was founded in 1987 and is a privately owned company. We specialize in the creation and deployment of business applications using new or existing technologies and services. We have a team of individuals that understand the broad range of technologies being used in today's environments. Our customers include small businesses using Internet technologies to corporations using very large mainframe systems.
Quite often, to reach larger markets or provide a higher level of service to existing customers it requires the newer Internet technologies to work in a complementary manner with existing corporate mainframe systems. We specialize in preparing applications and the associated data that are currently residing on a single platform to be distributed across a variety of platforms.
Preparing the application programs will require the transfer of source members that will be compiled and deployed on the target platform. The data will need to be transferred between the systems and may need to be converted and validated at various stages within the process. SimoTime has the technology, services and experience to assist in the application and data management tasks involved with doing business in a multi-system environment.
Whether you want to use the Internet to expand into new market segments or as a delivery vehicle for existing business functions simply give us a call or check the web site at http://www.simotime.com
