can any one guide me how should i do performance testing on database size for sql server. I dont know how to read the execution plan, though i have read many document but still i am not clear. For are the reports which shows the performance has been down and its all accurate.
I am trying to improve the performance of a query. No matter how badit runs the first time, it runs really fast the second time.So how can I tell if I've done anything to improve the query if italways comes back quickly after the first run? I assume thequery/data/plan is in cache - how can I clean it out for my session?Thanks in advance for any help you can provide -

Is it a bug or what?
Hi, I tried to use the RETURN_VALUE of a stored procedure in updata / delete commands with a sql-datasource and a stored procedure. The thing works fine with the insert command.But it fails with "too many arguments..." in delete / update. I also tried to handle the updating event like this: protected void sqldsReportSelect_Updating(object sender, SqlDataSourceCommandEventArgs e) { SqlParameter sqP = new SqlParameter("RETURN_VALUE", SqlDbType.Int); sqP.Direction = ParameterDirection.ReturnValue; e.Command.Parameters.Add(sqP);} It brings the same error. Do I make something wrong or is this a bug? Regards Manfred
I'm a relative newbie to ASP.NET development (web development in general) so please forgive the ignorance. ;-) Ok, I'm using VWD to design and test my application and I'm using the standard membership provider system. I've read in various places not to muck around with the aspnet_* tables as it can cause havoc hehe. Therefore, I've created my own Member table to accommodate more fields that the aspnet_Users table does not have (since I don't want to mess around with that table) such as address, city, town, zip, birth date, etc. Obviously, I have a field in Member that corresponds to the userId primary key in aspnet_Users. Now, there are times when I need to display the username of a person's profile on a page. SELECT aspnet_Users.UserName<br>FROM aspnet_Users, Member<br>WHERE querystringid=Member.memberId AND Member.userId = aspnet_Users.UserId Now, this seems fine and dandy when there are few entries in the aspnet_Users table, but what if I tried that query when aspnet_Users grew to a hypothetical one million entries?? Does anyone know if those fields in aspnet_Users are properly indexed? I can't seem to determine one way or another with VWD's database explorer. I don't want to run the risk of a full table scan. But if those fields aren't indexed, I don't know if I should modify that table in any way. What to do? TIA
I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database. I have a very simple dilemma. In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields. It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table. In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters. The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%') If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null> My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>. For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null> (accounting for about 95% of the records in the database). Thanks in advance Simon
I am using SqlServer 2005 Express Edition. I have written a stored procedure that has a transaction to make sure that it rolls back in case of failure. Is there a way to test that the transaction works. I don't now how to cause an error that would cause the transaction to roll back and raise the error with the details of the exception. Thanks, laura
hello everyone i was hoping to get some help. i have sql server2000 and iis5.1 running and im using vbscript through asp. i have a table that has two keys so that together they make a unique key. so i am trying to test my table in asp so that if there is a duplicate unique key inserted then show an error... Can anyone help me?
I want to run remote procs from a local - central proc, but don't want to crash my proc if the remote NT Server or SQL Server is not available. So, I want to test for NT and SQL availability first.
/* I find the server-dbasename name in a lookup table, and then build dynamic script */ SELECT @DBName = "<SRVRNAME~DBASENAME>" SELECT @QueryString = N'master..xp_cmdshell "ECHO >' + SUBSTRING(@DBName, 1,6) + 'pipesqlquery", no_output' EXEC @Results = sp_executesql @QueryString
SELECT @Results /* <-- testing here.... */
=====================
If the NT / SQL is running, "@Results" should = 0 (success on the ECHO to the PIPE) If the NT / SQL is NOT running, "@Results" should = 1 (error on the ECHO to the PIPE)
If I test in QA, I get the expected "@Results" values.
If I run the proc, I get "@Results" = 0 for both events, and them my proc fails on the remote proc call if the NT / SQL is NOT running.
I don't know how to write DMO in TSQL to try that. I have also tried using 'odbcping' too.
HINTS? Better way to test remote NT / SQL is NOT running?
i have performed all the steps for the replication there are two problems i encounytring (i) how to check whether the replication is working or not (ii) can replication on the subscribing server automatically create the table which publishing server is publshing (iii)please tell me someother forums for sql server
what my knowledge says that in replication if i modify the data at one place it should automatically be modified in the subscribing server but this thing is also not happening (its not flashing any error message as such) please tell me what all things i need to do to make sure that everything starts working

Has anyone ever heard of using Response.Write to test sql queries in the query designer? Here is the actual suggestion I was given recently:
Response.write your sql query. Copy the query to your db query tool and run the query. Adjust the query as necessary to return the recordset you desire. When you have the proper query, adjust your asp code.
The query editor/designer doesn't like certain symbols and extraneous code. So how exactly can you use Response.Write with a sql query without getting errors in designer?
I've begun some testing with the June beta of SQL 2005. One problemI've hit is with scalar-valued functions. The error I often get whenexecuting functions is "Select statements included within a functioncannot return data to a client.". These same functions are workingfine under SQL 2000.Has anybody seen this behavior or know what the deal is?
I've started researching on Unit Testing and I must admitI had never heard of Unit Testing until a couple of monthsago. Obviously I am interested in Unit Testing StoredProcedures.I read the TSQLUnit documentation (not all of it) and i also raninto a newsgroup post saying TSQLUnit is very small comparedto NUnit. The conclusion I am making out of this post is thatI should rather spend time resarching/reading about NUnit thanTSQLUnit. Is that a good assessment?I would like to you what you use and if you use actuallyUnit Testing or some other method? I ran into White Box/Black BoxQA testing. All these are new to me. Any good place to read about"Extreme Programming"? I ran into one link that I saved it at work.That's one place i will read more.Any links, documentation or books you would suggest?I searched Amazon and I didn't find anything interestingregarding SQL Server and Stored Procedures.Thank you

How do I test failover to point to the mirrored database instead of the principal without having to stop the primary instance? I would like to just bring the mirrored database on the primary instance to an offline status and see that the same database on the mirrored instance getting activated as the primary. This does not happen if I try to put the database on the primary server "offline" as it complains that any database that is being mirrored cannot be taken offline.
At the moment, the only way (that I know of) to test a subscription seems to be to schedule it a few minutes ahead in time and wait for it to happen. Dies nayone know if there are plans for and "Execute" or "tTst" button? It would be nice to have one.
i've been informed that one way to test a query is to execute and roll-back it back as a transaction. my question is the following: using the aforementioned mechanism, how can i examine the database state before the query is rolled-back?
How does one determine in a VS load test the exact limit of the number of users the report server can handle without failing?

Hi I’ve got a simple SQLdataSource which is wired up to a gridView. When the page loads, it’s sometimes likely the data source would contain no data – how can I test for that in the code behind (no data)? I’d like to only show a button if there is data? I’m using ASP.NET 2.0 with C# Many thanksRichard
Hi I really need your help. I’ve got a table with 4 columns – username (a string of text), dateTime (a date and time), duration (time in minutes), roomID (URL). I really need some help with writing up some code behind to check if a user has permission to continue. I’ve got the first bit, but I need help with collecting the data and testing it: SqlConnection conn = new SqlConnection(Global.ConnectionString); SqlCommand cmd = new SqlCommand("select * from tblActiveSession where Username=@Username", conn); SqlParameter paraUsername = cmd.Parameters.Add("@Username", SqlDbType.NVarChar); paraUsername.Value = this.txtUsername.Text; try { conn.Open() This is where I need the help. What I need is to test each row against the following: If now() is within the allowed time frame – greater than dateTime, but less than dateTime + duration, then break the loop and redirect to roomID. I really hope this makes sence, and I’m greatful for any help. Many thanksRichard
