SQL Processor Using File Input is a database facility invented by IBM for interfacing with their DB2 system. It is accessed from within TSO ISPF from the DB2I Primary Option menu. SPUFI allows direct input of SQL commands in the TSO environment, rather than having them embedded within a program.
Already i have some 10 queries in SPUFI. Now I want to write one more single line SELECT in the same SPUFI Input file and execute. So first we will comment all then insert new query in the first line.
Hi Couldn't understand ur query. SPUFI result is moved to a output dataset itself. And If u mean SPUFI in batch then use DSNTEP2 (search forum ).

Minimizing Overhead. OPTIMIZE FOR n ROWS: When an application executes a SELECT statement, DB2 assumes that the application will retrieve all the qualifying rows.This assumption is most appropriate for batch environments. However, for interactive SQL applications, such as SPUFI, it is common for a query to define a very large potential result set but retrieve only the first few rows.
Understanding Spufi output. There are various ways to execute SQL statements in a mainframe.. This post is mainly to understand the output of the query which is run through SPUFI. First let’s see the sample spufi output. DSNE617I COMMIT PERFORMED, SQLCODE IS 0 DSNE616I STATEMENT.
So, please check your product properly. Then go to SPUFI, you can also use QMF for creating the table. Here, we will get to SPUFI option 1, we have to give input filename “INPUT.FILE.HERE”, where we have to write SQL operation and then get the output of the SQL operation from “OUTPUT.FILE.HERE”.
Summary: in this tutorial, you will learn how to use the Db2 FETCH clause to limit the number of rows returned by a query. Introduction to Db2 FETCH clause. When you use the SELECT statement to query data from a table, you may get a large number of rows. However, you only need a small subset of these rows. Therefore, to limit the rows returned by a query, you use the FETCH clause as follows.
Dear readers, these DB2 Interview Questions have been designed specially to get you acquainted with the nature of questions you may encounter during your interview for the subject of DB2.As per my experience good interviewers hardly plan to ask any particular question during your interview, normally questions start with some basic concept of the subject and later they continue based on further.

Note the number of rows and columns; several columns are repeated more often than strictly necessary.To query for a result containing all tables in the system, we need to use the SYSIBM.SYSTABLES table, which is a catalog containing a record for every existing view, alias, or table. Note: Since SYSIBM.SYSTABLES contains a row for each of the three object types (view, alias, table), from now on throughout this little tutorial we’ll refer to each row as a potential object, rather than.We are trying to setup an automated process that will interact with DB2. We will need to execute commands that would normally be done through SPUFI interactively. So my question is; is it possible to run SPUFI in Batch and if so, how?
