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