I'v been scouring the MSDN library and asking in newsgroups, forums, etc. on a way to extract [only] the time from a DateTime field (for a stored procedure) and no one could answer my question. then I tried this in QA:
select right(getdate(),7)
and I found an answer. I'm now looking for someone to prove this is either a golden egg, a goose egg, or a documented feature I missed and if so where, so I can learn from it.

w/ SqlServer, is there anyway to pack a number of calls to the same stored procedure into a single round-trip to the DB short of dynamically writing a T-SQL block? For example, if I'm calling a procedure "Update Contact" which takes 2 params @Campaign, @Contact 20 times how would I pass in the values for those 20 diffrent versions?
View 6 Replies View RelatedIve got a List<sqlCommand> and I want to execute all the commands in it, but only using one trip to the database. I dont need any return values from any of these commands. Most of the commands are update/insert/delete. Sometimes after a insert command there may be a command "set @NEWID =identity_insert" to facilitate the next insert to a related table, but thats the only other type of command to insert/update/delete.I am using microsofts enterprise data application block. I want to execute all the commands in the list with just one trip to the database. Would the following code achieve this : db = DatabaseFactory.CreateDatabase("wlmAdmin"); foreach (SqlCommand sc in saveCommands) { db.ExecuteNonQuery(sc); }or would this make multiple trips to the database? Im not 100% on whats going on behind the db object. If I create the db Item in the constructor of my class using "db = DatabaseFactory.CreateDatabase("wlmAdmin");" would this mean that every instance of that class would maintain an open database connection throughout its scope/lifetime?Ive created the class to retrieve all data using a single stored procedure and then when saving, the class builds a List of SqlCommands which as Ive mentioned I want to execute in one trip, to make the number of trips to the database as small as possible. Because of this I don't need the db object maintain an open connection to the database all the time. However It doesnt seem to have any dispose methods so Im not clear on how it operates.In the case that the code above opens a connection for each command, how would I got about batch executing the queries in one trip?Thanks,C

I need to write a select query that will run all returned results through a separate stored procedure before returning them to me.
Something like....
SELECT TOP 10 userid,url,first name FROM USERS ORDER by NEWID()
......and run all the selected userids through a stored procedure like.....
CREATE PROCEDURE AddUserToLog (@UserID int ) AS INSERT INTO SelectedUsers (UserID,SelectedOn) VALUES (@UserID,getdate())
Can anyone help me to get these working togethsr in the same qurey?
Thanks
I would like to update/insert data into a Orderhearder Table along with the related details into the corrosponding OrderDetails Tables. Can this be done using a single stored procedure or do we have to make one call to the UpdateOrderHeader Stored Procedure and loop thru all the details and call the UpdateOrderDetails Stored Procedure. How do we handle the Transactions in such a case ?
Thanks
