Getting Started with DB2 Express-C

Chapter 5 – DB2 Tools 101
used a semi-colon for the statement terminator, there would have been a conflict in the
script with the one used for the SELECT statement, resulting in an error reported by DB2.
CREATE FUNCTION f1()
SELECT … ;
…
END!
Listing 5.2 - Contents of the script file functions.db2
To inform DB2 that a different statement termination character is being used, use the -d
flag, followed by the terminator character desired as shown below:
db2 –td! –v –f functions.db2 –z functions.log
To find out more about the other flags that can be used from the Command Window or
Linux shell, use this command:
db2 list command options
5.10.2 Operating system (shell) scripts
Operating system scripts provide greater flexibility and power than SQL scripts, as they
give you the possibility to add additional programming logic. They are platform dependant,
but they support parameters and variables. Listing 5.3 shows an example of a simple
Windows operating system (shell) script.
set DBPATH=C:
set DBNAME=PRODEXPR
set MEMORY=25
db2 CREATE DATABASE %DBNAME% ON %DBPATH% AUTOCONFIGURE USING
MEM_PERCENT %MEMORY% APPLY DB AND DBM
db2 CONNECT TO %DBNAME% USER %1 USING %2
del schema.log triggers.log app_objects.log
db2 set schema user1
db2 –t –v –f schema.db2 –z schema.log
db2 –td@ -v –f triggers.db2 –z triggers.log
db2 –td@ -v –f functions.db2 –z functions.log
Listing 5.3 - Contents of the operating system script file create_database.bat
To execute this operating system script from the command line, you would issue the
following command on Windows:
create_database.bat db2admin ibmdb2
where db2admin is the userID and first parameter of the script, and ibmdb2 is the
password and second parameter of the script.
On Windows using the “bat” extension tells the operating system that this is a batch
executable file. On Linux, you need to change the mode on the file to indicate the file is
