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,

Hi,I am seeking the help of volunteers to test some software that I'vedeveloped which facilitates distributed two-phase commit transactions,encompassing any resource manager (e.g. SQL/Server or Oracle) controlled byMicrosoft's Distributed Transaction Coordinator in a Windows2000environment, with any resource manager under the control of DECdtm (e.g. Rdb(or Oracle via the XA Veneer)) in a VMS environment.[Yes, at some stage, I hope to sell this software and make money out of it,so unless you have a large philanthropic streak or are simply a techie wholikes to stay on top of Windows<->VMS connectivity issues, then you may wishto look away now. But if you do choose to participate, then rest assuredthat I have no interest in your personal or company details. (Just yourwork-rate :-)]What differentiates my Transaction Manager software from existingTransaction Monitor packages that are already in the marketplace (and whyyou should be interested) is that it is based on the Transaction InternetProtocol TIP standard. (RFC 2372) For those of you who don't know, thebeauty of TIP's "Two-Pipe" strategy is it's application-pipe (or middleware)neutrality. Whereas most XA implementations mandate homogenous TransactionMonitor deployments (such as Tuxedo everywhere, Encina everywhere, MQSerieseverywhere, ACMSxp everywhere and so on . . .), hotTIP from TIER3 Softwaregives you complete freedom to choose the middleware product(s) that bestsuite your particular application and heterogeneous network needs.Would you like to talk to VMS with TIER3 Sockets, COM or DCE/RPC? BEAMessageQ, IBM MQSeries or HTML? The choice is yours and yours alone. Butonce you realize that you need to encase your critical transactions withinthe ACID properties of a true Heterogeneous Two-Phase Commit then you willcome to the conclusion that you need a Transaction Manager that looks a lotlike this.Another drawback of traditional "One-Pipe" strategies is that they precludethe run-time determination of transaction participants. (Functionalitywhich may be advantageous in a wide-area or Internet based application.)Anyway, this is what I have: -On the Windows side, you need absolutely *NO* additional software! I'llreply to this note with a brief description of the COM+ and DTC functionsthat you would need to invoke in order to successfully push a MTS/DTCtransaction to VMS. NB: These are standard Windows APIs that are fullydocumented on MSDN.On the VMS side, I have a VMSINSTAL saveset that (all zipped up) is some150KB that I'm happy to e-mail to you along similar lines to the VMShobbyists (non-commercial use) license. I'll reply to this note with anInternet Daemon (INETd) example of code that uses my software to cedetransactional control, over an SQL insert into a Rdb database, to MTS/DTC.It's under 500 lines long and contains all of the DCL, 3GL, SQL required toproduce a working example of a TIP-2PC capable TCP/IP auxiliary server. Thisexample will insert a row into the MF_PERSONNEL.Employees table on the VMSside in co-operation with Windows2000 MTS/DTC client that is inserting a rowinto the NORTHWIND.Employee table. Commit them all or roll them all back.So, in summary, If you'd like to volunteer to put hotTIP through it's pacesthen simply reply to this mail.Regards Richard MaherPS. The following are a few functionality restrictions with the currentversion of my software that may effect your decision to participate: -1) Transaction has to be started/mastered/coordinated by W2K MTS/DTC2) Transactions cannot be PULLed from VMS and must be PUSHed from W2K3) No cluster-wide recovery.(If a txn falls over after being prepared then you have to wait for thatspecific node to become contactable again even though that lovely RDMrecovery job is sitting on another node protecting the database until myhotTIP TM tells it to commit or abort.)4) There is currently no Alpha or Itanium version available. The Alpha portis currently in progress but, for the time being, you'll either need a VAXor a VAX emulator on your PC.
View 7 Replies View RelatedHi there,
I have decided to move all my transaction handling from asp.net to stored procedures in a SQL Server 2000 database. I know the database is capable of rolling back the transactions just like myTransaction.Rollback() in asp.net. But what about exceptions? In asp.net, I am used to doing the following:
<code>Try 'execute commands myTransaction.Commit()Catch ex As Exception Response.Write(ex.Message) myTransaction.Rollback()End Try</code>Will the database inform me of any exceptions (and their messages)? Do I need to put anything explicit in my stored procedure other than rollback transaction?
Any help is greatly appreciated

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.
Here's my code.
====================
DECLARE
@DBName varchar(22),
@QueryString NVARCHAR(130),
@Resultsint,
@ResultsTxtvarchar(31)
/* 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?
Thanks in advance.

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?

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.

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#

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
Pop quiz hotshots:
I am creating a View in SQL2000 where i concatenate values from multiple tables. My problem is that if one of the values is null then the whole string is null, so I would like to know how to test for nulls within the Select part if the View.
Select
Titles.Title + ' ' + User.Forename + ' ' + User.Surname AS FullName,
For example;
If User.Forename is null, I still want to return Titles.Title and User.Surname as a concatenated string.
I’ve tried I few things like places if statements within the Select part but I can’t get it to work.
Many thanks

My previous experience is with php and MySQL.
I currently have Apache, MySQL and php running on my local machine to enable me to test php code on localhost
I've been asked by a colleague if I'll work on an SQL 2000 database they're having trouble with. They said they will provide Visual.net, SQL 2000 and any other software I need.
I'm completely in the dark on this, but have some starting questions:
To test my code, will I need to set up a sever on localhost?
Will I need other software than Visual.net and SQL 2000? I'm using DW MX for my web stuff.
Whre can I find a basic introduction to ASP / SQL 2000 in the form of a tutorial?
How fast does this combination run? The database has 25,000 rows and 6 columns. What would be a reasonal expect time for a result?

Is there any way to test if a table exists in the temp dB. In a procedure I create table called ##Test but I want to test if it exists before it's created and if it does I want to delete it. (It has to be a ## table because it's in a procedure being called in another procedure depending on an IF statement). The reason I want to do this is that I have multiple users and Occasionally they get the ... There is already an object named '##Test' in the database. error
Many Thanks
