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

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

i am using SQL server 2005
in affect to what is said about ANSI NULL ON and
QUOTED IDENTIFIER ON,
I do not get NULL if i place empty records in tables
instead only an empty space appears

please givme more details on these

a SELECT statement using WHERE Emp_Name= NULL returns zero rows even if there are null values in Emp_Name.

A SELECT statement using WHERE Emp_Name NULL returns zero rows even if there are nonnull values in Emp_Name.

When SET ANSI_NULLS is OFF, the Equals (=) and Not Equal To () comparison operators do not follow the SQL-92 standard.

A SELECT statement using WHERE Emp_Name= NULL returns the rows with null values Emp_Name.

A SELECT statement using WHERE Emp_Name NULL returns the rows with nonnull values in the column.

SET ANSI_NULLS also must be ON for executing distributed queries and when creating or manipulating indexes on computed columns or indexed views.

If SET ANSI_NULLS is OFF, CREATE, UPDATE, INSERT, and DELETE statements on tables with indexes on computed columns or indexed views will fail. SQL Server will return an error listing all SET options violating the required values.

When executing a SELECT statement, if SET ANSI_NULLS is OFF, SQL Server will ignore the index values on computed columns or views and resolve the select as though there were no such indexes on the tables or views.

If you want a script to work regardless of the ANSI NULSS database option or the setting of SET ANSI_NULLS, use IS NULL and IS NOT NULL in comparisons that may contain null values.

Thank you
