Demonstration Applications

Visual COBOL provides several demonstration applications or programs for the DB2 ECM.

DB2 ECM – Windows Environment

You can run these samples from the Samples Browser. To start the Samples Browser, click Start > All Programs > Micro Focus Visual COBOL > Samples .

Note: On Windows 8, Windows 10, and Windows Server 2012, you use the Start screen to invoke programs. To start the Samples Browser on Windows 8, Windows 10, or Windows Server 2012, go to the Start screen and click the Samples tile.

All DB2 ECM samples are listed on the Show managed only list in the Samples Browser.

The source files are located in subdirectories under %PUBLIC%\Documents\Micro Focus\Visual COBOL\Samples\Eclipse\COBOL\sql\db2ecm.

Each sample application comes with a Readme file to explain how to use the application.

The following applications are provided:

DB2 ECM - Connect
Shows the syntax variants for connecting to and disconnecting from a DB2 database using Type 1 CONNECTs that IBM DB2 LUW supports.
DB2 ECM - Db2storedproc
Shows how to create and call a COBOL stored procedure using IBM DB2 LUW.
DB2 ECM - Dynamic
A simple example of using dynamic SQL with IBM DB2 LUW, performing a variety of SQL operations. If this program was written as a STATIC SQL program, it would have to be broken apart into two programs, since static SQL requires that the table exists beforehand or it would cause a Compiler error.
DB2 ECM - LOB Data Types
Illustrates the use of LOB LOCATOR and VALUES functions to retrieve LOB data from DB2 LUW.
DB2 ECM - Select
A simple example of using both singleton SELECT and cursor-based FETCH statements with IBM DB2 LUW.
DB2 ECM - Whenever
Shows how to use EXEC SQL WHENEVER statements for error handling, and the DB2(MSGAREA) Compiler directive to specify a COBOL variable for retrieving error message text larger than the 70 bytes provided in SQLERRMC.

DB2 ECM – UNIX Environment

A number of DB2 ECM sample programs are supplied. The source files for these samples are located in $COBDIR/demo/db2.

Each sample program comes with a progName.txt file to explain how to use the program.

db2test1.cbl
Shows the syntax variants for connecting to and disconnecting from a DB2 database using Type 1 CONNECTs that IBM DB2 LUW supports.
db2test2.cbl
A simple example of using both singleton SELECT and cursor-based FETCH statements with IBM DB2 LUW.
dynamic.cbl
A simple example of using dynamic SQL with IBM DB2 LUW, performing a variety of SQL operations. If this program was written as a STATIC SQL program, it would have to be broken apart into two programs, since static SQL requires that the table exists beforehand or it would cause a Compiler error.
lobdemo.cbl
Shows how LOB LOCATOR and VALUES functions to retrieve LOB data from DB2 LUW.
whenever.cbl
Shows how to use EXEC SQL WHENEVER statements for error handling, and the DB2(MSGAREA) Compiler directive to specify a COBOL variable for retrieving error message text larger than the 70 bytes provided in SQLERRMC.
