You can save a .sql file to your hard drive, and execute it using the DB2 command line using:
db2 -vtf C:\path\to\test.sql
-v echoes the command text back to the command line
-t sets the statement terminator to ;.
-f tells the command line to load the commands from the file.
See other command line options, http://publib.boulder.ibm.com/infocenter/db2luw/v9r7/topic/com.ibm.db2.luw.admin.cmd.doc/doc/r0010410.html.
