How can I make sure that a couple of commands are either all executed on the database or none of them. For example right now I have an insert, update and delete command. I'm calling each of them with a SqlCommand. So I am afraid that that one of them might be executed, then there's a bad connection and the other two are not. How can I prevent this so that only all commands or nothing is executed on the database?
View 2 RepliesI'm running asp.net 2.0 and acessing MSSQL 2K. I am trying to run a query in which I need to set up variables first.

I was wondering if it was possible to run 2 queries at the same time,IE rather than runningexec query1 exec query2 and having to wait for query1 to finish before query2 started, just have them run at the same time (they're not conflicting).I want to do this in TSQL, not by opening another query window in vs2005.
View 2 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

View 9 Replies View RelatedHi all,
I am writing a portion of an app that is of intensely high online eCommerce usage. I have a question about identity columns and locking or not.
What I am doing is, I have two tables (normalized), one is OrderDemographics(firstname,lastname,ccum,etc) the other is OrderItems. I have the primary key of OrderDemographics as a column called 'ID' (an Identity Integer that is incrementing). In the OrderItems table, the 'OrderID' column is a foreign key to the OrderDemographics Primary Key column 'ID'.
What I have previously done is to insert the demographics into OrderDemographics, then do a 'select top 1 ID from OrderDemographics order by ID DESC' to get that last ID, since you can't tell what it is until you add another row....
The problem is, there's up to 20,000 users/sessions at once and there is a possiblity that in the fraction of a second it takes to select back that ID integer and use it for the initial OrderItems row, some other user might have clicked 'order' a fraction of a second after the first user and created another row in OrderDemographics, thus incrementing the ID column and throwing all the items that Customer #1 orders into Customer #2's order....
How do I lock a SQL table or lock the Application in .NET to handle this problem and keep it from occurring?
Thanks, appreciate it.

Comments? Suggestions, I am not positive about how to fix this.
Using SQL Server Express 2005, I have two databases. AppDB - The main application database.GeoDB - A somewhat static ZIP code / states / other geographic stuff databaseI need to have some foreign key columns in tables in AppDB reference columns in the GeoDB database tables. Eventually other application database besides AppDB will be doing the same thing in our infrastructure. After googling and reading for days, here is what I
think I know:You cannot create foreign keys that reference tables in another database in SQL Server.You
cannot create foreign keys that reference columns in a view, and you definitely cannot make an index on a view that has base tables in another database.You can create a trigger that references tables in another database, but this can be flaky? (nested/recursive trigger problem).SQLServer
2005 supports multiple schemas within the same database. Maybe I should logically separate my databases this way? Seems like it would be a tough solution to manage since I already have some databases live in production that will eventually use this 'static' GeoDB. Also, seems like it
wouldn't be as portable as keeping the GeoDB info in its own database,
but maybe I'm being too software engineer-ish here - afraid of low
cohesion, high coupling.I will greatly appreciate any advice I can get, or any more options I am missing. Thanks,Adam Nofsingerucnmedia.com
Using the new referential integrity constraints that will be made available, will it allow us to manually define the relationships between entities even if there is no true foreign key constraints setup in the database?
Lets say we deleted the FK_Orders_Customers in Northwind between orders and customers.
Or is this ability available now?
Thank for your time.
I am not sure I need more integrity on my DB. My DDL are down below.

Where should tests for data integrity be done, a few examples:
Inserting data but the underlying data has changed?
Adding data, say an order item row, but since going to that screen the order (and as a result all its order items as well) have been deleted?
It's just I'm starting to see even the simplest of stored procedures as being quite complicated. What puzzles me is a I see lots of INSERT stored procedures with none of this checking in, or returning error codes?
So are they badly done or am I missing somethign?

On weekends I have Integrity Checks scheduled to run. Many of these fail for individual databases because users do not log off and the databases cannot be switched to single user mode.
I have checked Books-on-line and have not yet stumbled onto a TSQL command that breaks the connections.
Is there a TSQL command to do this? If not, how can these connections be broken?
I used to work with little databases and throw everything into a table with no relation, and modify them all individually. Now I've learned about referential integrity, makes things a lot easier.
My question is, now what? Say I have a Customers table and an Orders table (to keep it simple). If custID is the primary key in customers, foreign key in orders, then if I want to insert into Orders, I need the custID. So those kinds of things I need to keep stored in a session state and insert them like that, correct?

Hi guys,
Is there a way of finding the foreign keys for a table and therefore determine weather any referential integrity rules would be broken if a record was deleted?
For example. You have an author you want to delete, but that author has books. You call a procedure to delete the author. The stored procedure checks the foriegn keys, checks the tables and determines what is in them and if any tables have records that would be "orphaned" you return an error reporting what tables have the "would be orphaned" data in them.
It need to be fairly generic int he manner that it checks the foreign keys and the sub table data.
This is on behalf of a guy at work so "requirements" may change. ;)
Anyone got some ideas??
Cheers,
Shaun

View 1 Replies View RelatedI am experiencing a situation where I issue a lengthy SQL command to MS SQL Server 7.0 through MTS and it "disappears" - no errors or recordsets are returned. The command is "SELECT * FROM CUSTOMERS WHERE LASTNAME LIKE 'SMITH%'". When I issue this command from SQL Query Analyzer it takes 27 seconds to return 87 rows. When I issue this exact same command through MTS it does not return at all.
I've used the SQL Profiler to analyze the requests. It shows the commands from MTS starting but they never stop (or at least the profiler never reports them as stopping). The same commands coming from Query Analyzer are reported as starting and stopping without fail.
Here's a twist: I can issue less demanding commands (ie, one that doesn't take so long to process) through MTS and they come back fine. For example, when a user logs into my application, I use an SQL statement to verify the user name and password and status the user as logged in. This is routed through MTS and it comes back fine in less than a second. Same application, same PC, same MTS and SQL server, same SQL database. The only difference is that the CUSTOMERS table has over 800,000 records and the USERS table has only 5 records.

Hi,
I am very new to sql server and I have been reading up on the dbcc commands. For instance, DBCC SHOWCONTIG where do I execute this command? I went into the cmd prompt and opened osql and typed:
1> DBCC SHOWCONTIG
2> GO
This gives me the information for what I assume is the master database. But, how do I use this command under the other databases?
Also, I have been trying to learn how to determine when to do index maintenance by using the index tuning wizard. But, I don't know what a workload is. Can someone point me in the right direction or give me some information about this topic.

Hi
Please can someone point me in the direction, i built a very badly designed database consisting of only one huge table when i first started databases, since learning about normalization i have designed and set up a new database which consists of many more tables instead of just the one. My question is where do i start in transfering the data from the old single tabled database to my new multi-tabled database?
I have MS SQL server 2005 managment studio if that helps, but want to transfer around 200,000 rows of data into the new database. Both new and old databases are on the same server.
