please use meaningful titles when posting
posts with silly/useless titles will usually be skipped by people looking at the forums
if You are sloppy in posting You will lose many opportunities
same comment applies to Your other post titled jcl
it would be useful for you to read and meditate on

so that I am sure that the information requested can be reached with a very small effort

Hello,
As there is no such thing as a null value, a null value cannot be "passed".
Suggest you read about what NULL really means in db2.
NULL (by definition) is the absence of any value at all.
There are zero ways. . .how many ways to pass the null values to db2 table

the question could be :
How do you set a column (empid) of a certain row in a certain table to null ?
the number of ways are endless , but the most common in COBOL is using a null-indicator variable.

exec sql
update test1
set empid = null
where col1 = 'B'
end-exec
exec sql
insert into test1(col1,empid) values ('E',null)
end-exec
exec sql
insert into test1(col1) values ('D')
end-exec
move -1 to ws-empid-ind
exec sql
update test1
set empid = :ws-empid:ws-empid-ind
where col1 = 'B'
end-exec
move -1 to ws-empid-ind
exec sql
insert into test1(col1,empid) values (:ws-col1,:ws-empid:ws-empid-ind)
end-exec
update test1
set empid = null
where col1 = 'B'

I can explain it to you, but i can not understand it for you.

Hello,
Did you read and understand the previous replies to this topic?
There is no such thing as a "null value" so no null value can be "passed".
The null indicator may be set, but there is no value to place in the column as there is no value that is null. . . There are 256 possible bit patterns for one byte (x'00' thru x'FF'). Not one of these possible values is a null value.
NO, it cannot. . .using load utility u can pass the null values

RENGANATHAN ,
Your 2 most recent posts to this topic have been deleted. They were wrong. . .
It doesn't matter how you say it, there is NO null value. . . A column may be nullable, but there is no null value
You can test whether a column IS NULL, but this does test for a null value in the column.
Suggest you concentrate on a more thorough understanding of the basics before posting contradictions. . .

Hello,
From your earlier post:
One of the things we (the old guys<g>) stress is the importance of using the correct terms. There are many, many things that are "interchanged" that convey incorrect information.
From your earlier post:

Yes, we understand this - we were learners once alsoam just a learner only
Not to worryif there is anythng wrong in that means regret me....
