How do i know whats the default values on which table and which column and whats the default value
It should be like this
Table column constraint_name value
emp emp_id DF_emp_emp_no 1
emp join_date DF_emp_cur_date getdate()
How can i get these results on all the tables in my DB.
Thanks.sp_help '<table_name>'
After the column list of index(es), the proc will list any constraints by column name.|||select object_name(c.id)+'.'+col_name(c.id, c.colid)+' - '+
object_name(c.constid)+' value: '+text
from sysconstraints c
inner join syscomments sc on c.constid = sc.id
where(c.status & 5)= 5
and objectproperty(c.id,'IsMSShipped')= 0
order by object_name(c.id)|||Buy that man a drink!

Defaults for Functions and Parameters
I need to be able to get the defaults specified for SQL functions and procedure using sql. I see in the SQL Server 2005 docuementation that for CLR Functions, the defaults used in the create are store in sys.parameters. I need to find out what the defaults are for SQL functions and procedures. I know they are store in the definition of the function (or Procedure), but I want to avoid parsing the text. Thank you.
CREATE FUNCTION [dbo].[myfunc] (@.first int = 1001)
RETURNS int
AS
BEGIN.......
There is no way to get the defaults for TSQL SPs/UDFs without parsing the definition.defaults
Can someone give me a simple example of how you use the
defaults in sql server 2000? I cant figure it outSee following exmaple:
(while creating table)
CREATE TABLE multinulls (
a int NULL,
b char(5) default 'hello'
)
you can also create default as an object and bind it to table's column
Ex:
CREATE DEFAULT abc_const AS 'abc'
GO
sp_bindefault abc_const, 'test_defaults.char1'
GO

Setup.
For example Open EM, Create a table two columns
Column 1 name it Log_Date datetime with a default of getdate()
Column 2 name it test_data varchar(20)
Open the table and insert something on the test_data column click on the
exclamation point to execute
or simply use query analyzer
BEGIN TRANSACTION
CREATE TABLE dbo.test0001
(
log_date datetime NULL,
test_data varchar(20) NULL
) ON [PRIMARY]
GO
ALTER TABLE dbo.TEST001 ADD CONSTRAINT
DF_Table1_log_date DEFAULT getdate() FOR log_date
GO
COMMIT
INSERT INTO TEST0001(TEST_DATA)
SELECT 'TEST1'
SELECT * FROM TEST0001
If you create a new default on a column to an existing table with data then
you need to do something like
insert into test0001 default values
select * from test0001
Hope this helps

Defaults
1) Defaults are applied before transactions.
Defaults incur more overhead than constraints but less than triggers.
Defaults are less functional than constraints or triggers.
2) Defaults are applied after transactions.
Defaults incur more overhead than constraints but less than triggers.
Defaults are less functional than constraints or triggers.
3) Defaults are applied before transactions.
Defaults incur more overhead than constraints but less than triggers.
Defaults are more functional than constraints but less than triggers.
4) Defaults are applied after transactions.
Defaults incur less overhead than constraints or triggers.
Defaults are more functional than constraints but less than triggers.
5)5)Defaults are applied before transactions.
Defaults can only be applied to one column per row.
Defaults are less functional than constraints or triggers.
I go with option number 4. All are agree with me ?
Thanks

No - but the statements are poorly worded. Comparing the functionality of
defaults and constraints is inappropriate (even though MS has lumped them
together - a default is a type of constraint) since they have different
purposes. IMO, a default is less "functional" than a constraint.
Certainly, both are less functional than triggers. The terminology "before
transactions" and "after transactions" is meaningless. If I had to guess, I
would choose "before transactions" simply because the default is applied
before the insert statement completes.
I would choose 5 but the middle statement can be interpreted in different
ways. The part about "per row" is especially confusing (perhaps
intentionally) - defaults (and constraints and triggers) are never defined
at the row-level. A default is associated with a single column, but each
column can have a default.

Hi John,
I don't.
Defaults are applied, neither before or after transactions, but as part
of a transaction. Anything that is applied before or after a transaction
would not be affected by a rollback of that transaction. If I ever see a
case where the insert statement is rolled back but the default values
used in that statement persist in the database, I'll be on the phone
yelling "BUG" in MSPSS' ears before you can say "Rollback".
Defaults incur less overhead than triggers. I have never compared the
overhead of defaults to that of constraints, since this would be a
meaningless comparison. I can't replace either one with the other, they
yield different functionality. It would be about as meaningless as
comparing the costs of your car with that of your microwave oven.
You could call defaults less functional than triggers, but in the same
sense as calling a chair less functional than a pile of wood, a supply
of nails, a saw, and a hammer. You can make anything you want from the
wood, including a chair, but it takes much work. If you just want to sit
down for a while, using the chair is by far the better option.

Default Values and Subscriptions
I have a report that I run where the selected MONTH and YEAR defaults to the prior month and year. When I run the report it shows the parameter values show as June 2007. Which is correct since this is July.
If I schedule the report to run on the 1st of every month will it default to the prior month/year automatically (I have the "use default" box checked).
Hello,
As long as your default value is setup correctly and will work for any month (and January of the new year), yes, your subscription will use the default value when it runs.
