How to change the Default value of a Column

What's the SQL or is there a stored procedure
to replace the DEFAULT value of a COLUMN?
Dropping and re-adding the column seems overkill to me.
thanks in advance
You do an alter table to drop the constraint and then alter table to add it
back. You don't drop/add the column.

If you have auto named default names, you can use the following script,
substituting <table name> and <column name>:
DECLARE @.constraint_name SYSNAME
-- remove all the defaults
WHILE 1=1
BEGIN
SET @.constraint_name = (SELECT TOP 1 c_obj.name
FROM sysobjects t_obj
INNER JOIN sysobjects c_obj

INNER JOIN syscolumns cols
ON cols.colid = c_obj.info
AND cols.id = c_obj.parent_obj
WHERE t_obj.id = OBJECT_ID('<table name>')
AND c_obj.xtype = 'D'
AND cols.[name]IN ('<column names>'))
IF @.constraint_name IS NULL BREAK
EXEC ('ALTER TABLE <table name> DROP CONSTRAINT ' + @.constraint_name)

How to build a Service Broker Endpoint

Hi

first of all I should say I don't know anything about

Serviec Broker

I just want to use the SP_Send_dbmail stored procedure

to send an email from SQL Server instance to an email address for example <aa@.yahoo.com>

in the Surface Area Configuration I faced a message indicating there is no Service Broker endpoint for this inctance.

please tell me step by step and in detail what to do to be able to send an email from SQL Server and please try not to confuse me.

thanks.

pooyan.

A Service Broker endpoint is not necessary for using Database Mail. If you have sent mails using sp_send_dbmail and aren't receiving any e-mail messages, then connect to your database and look at the following view:

select * from sys.transmission_queue;

Does this report any messages pending to be delivered?

Hi

As you said I executed select * from sys.transmission_queue.

but there was no result set.

what's the problem? can it be because of security limitations? Because I can't execute

sp_send_dbmail stored proc in any database except msdb .

please tell me what to do.

thanks.

pooyan.

sp_send_dbmail only exists in msdb.

Do you see errors in select * from sysmail_log?
