Introduction
(Next) (Previous) (Table-of-Contents)

Structured Query Language (SQL) is a standardized language for defining and manipulating data in a relational database. A relational database may be perceived as a set of tables. The tables can be created, viewed, changed, manipulated or deleted in accordance with the relational model.

The SQL Connection provides a suite of sample programs and documentation that shows how to do practical task for creating and managing a relational data base. The sample programs use embedded SQL.

Embedded SQL is SQL syntax written within an application programming languages such as COBOL and preprocessed by an SQL preprocessor before the application program is compiled.

The SQL examples are written to compile and execute in the Micro Focus environment or an IBM Mainframe, DB2 environment. For the Micro Focus Mainframe Express (MFE) or IBM Mainframe (ZOS) environments sample JCL members are included. For Micro Focus Net Express and the Microsoft Windows environment sample CMD files are included. The Micro Focus SQL option is used as the Relational Data Base engine (XDB) for the Windows environment.

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.
