it doesn’t give records that contains null values is it..?

for eg: select * from employee where emp_city= null

The above query doesn’t give any record is it but if i use ‘is null’ in place of null i got the records that contain null values. Then tell me exactly what is the use of ‘ANSI_NULL is set to ON’

SET ANSI_NULLS ON
IF NULL = NULL
PRINT ‘same’
ELSE
PRINT ‘different’
–result: different

SET ANSI_NULLS ON
IF NULL IS NULL
PRINT ‘same’
ELSE
PRINT ‘different’
– result: same SET ANSI_NULLS OFF
IF NULL = NULL
PRINT ‘same’
ELSE
PRINT ‘different’

Thank you

Could you please explain about set quoted identifier on/off with example?

Thank you

set ansi_nulls on

select * from myTab where [name] is null
we will see result with name value is null

select * from myTab where [name] = null
we will not any see result

set ansi_nulls off
select * from myTab where [name] is null
we will see result with name value is null

select * from myTab where [name] = null
we will see result with name value is null

I am trying to create a stored procedure for SQL Server 2008 R2. I want this stored procedure to have uses_ansi_nulls as False.
My database’s ANSI NULLS Enabled property is set to False.
I’m creating procedure as below:

SET ANSI_NULLS ON
GO
CREATE PROCEDURE MY_SP

Procedure is created successfully but following query returns true.

SELECT uses_ansi_nulls, uses_quoted_identifier
FROM sys.sql_modules
WHERE object_id = object_id(‘MY_SP’)

Is there a way to create stored procedure so that above query returns false (SET ANSI_NULLS remain false).

correction ROWCOUNT not @@ROW_COUNT

Can you help me?

How to remove duplicate records from a table?

exact and accurate answer. thanks again .!!

Eg.. in your case the select * from table irrespective of the ANSI flag will result in
1 Steve
2 NULL
3 Mike
4 NULL

Try these two scenarios.
1. SET ANSI_NULLS ON
select * from table where name = NULL
2. SET ANSI_NULLS OFF
select * from table where name = NULL

Now I am sure you will find the difference.. Let me know how are you getting on this.

Cheers
Hari

1 Steve
2 NULL
3 Mike
4 NULL

When I used
SET ANSI_NULLS ON
select * from table
the result set is same as the above.
— But when I used
SET ANSI_NULLS ON
select Name from table where Name = NULL
It retrieves no result.
I did not understand why? there is nothing difference between setting the ANSI_NULLS ON and ANSI_NULLS OFF
in case of
SET ANSI_NULLS ON
select * from table

and

SET ANSI_NULLS ON
select * from table

Can u explain ?

SET ASNI_NULL OFF
select * from table where col1 = NULL
select * from table where col1 NULL
in one case definately you will get result

Hope this explanation helps. I found this from a forum and tried. I worked fine. So why not you guys try.

To handle NULL value in calculation use ISNULL function. SET ANSI_NULLS affect the result of equal to (=) and not equal to () comparision with NULL value.

example;
———————-
shape
a_table…
append a1_table bla bla… relation a to a1 …
append a2_table bla bla… relation a to a2 …
compute
sum (a1_money) as a1m,
sum (a2_money) as a2m,
calc (a1m – a2m) as adiff
—————————

“adiff” is empty if “a2m” is null…

ANSI_NULL is not work in these query.

do you have any solution ?
please help me immediately.

thank you.

When we should make them on and Off.

Thnx
