Hi all,
I have come across batch jobs using DSNTIAUL and some jobs use DSNTEP2 to execute th e SQL queries.
What is the actual diff between these 2 utilites.
Please let me know.

Hello, Sir, Logaas!
Here is definition of difference:
DSNTIAUL
The sample unload program. This program, which is written in assembler language, unloads some or all rows from up to 100 DB2 tables. With DSNTIAUL, you can unload data of any DB2 built-in data type or distinct type. You can unload up to 32KB of data from a LOB column. DSNTIAUL unloads the rows in a form that is compatible with the LOAD utility and generates utility control statements for LOAD. DSNTIAUL also lets you execute any SQL non-SELECT statement that can be executed dynamically.
DSNTEP2
A sample dynamic SQL program in the PL/I language. With this program, you can execute any SQL statement that can be executed dynamically. You can use the source version of DSNTEP2 and modify it to meet your needs, or, if you do not have a PL/I compiler at your installation, you can use the object code version of DSNTEP2.
