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?

Can anyone help me?
I am obviously a newbie to SQL Server but have been using Access for years and I have come up against what appears to be an age old issue concerning nulls and specifically the functions to test for them etc.
Below is the Access Query I am having difficulty with...
----------------------------------------------------------
SELECT DISTINCT Max(tbl_ScheduleDate.SchDate) AS CurrentDate, ([SchDate],"mmmm yyyy") AS MonthYear, tbl_Schedule.Area, tbl_Schedule.CP, IIf(IsNull(tbl_tmp_CP.CPID),"Not Uploaded","Uploaded") AS Loaded
FROM (tbl_Schedule INNER JOIN tbl_ScheduleDate ON tbl_Schedule.MaxMinID = tbl_ScheduleDate.MaxMinID) LEFT JOIN tbl_tmp_CP ON tbl_Schedule.CP = tbl_tmp_CP.CP
GROUP BY Format([SchDate],"mmmm yyyy"), tbl_Schedule.Area, tbl_Schedule.CP, IIf(IsNull(tbl_tmp_CP.CPID),"Not Uploaded","Uploaded"), tbl_ScheduleDate.SchDate, tbl_tmp_CP.CPID;
-------------------------------------------------------------
Ignore the Format() function as I know this is a problem and have a fix.
The problem is this field...
IIf(IsNull(tbl_tmp_CP.CPID),"Not Uploaded","Uploaded") AS Loaded
I am testing to see if data is loaded into table 'tbl_tmp_CP' that is related to 'tbl_Schedule' by checking if there is a null value or not and then adding the right response string value to a column called Loaded.
Can anyone suggest a way for me to do the above?
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 -
View 4 Replies View RelatedI have an application that is using ADO connection strings from multiple clients. One site with about 20 users was recently upgraded to a newer version of my application, and the number of connections to the SQL Server I'm told went from about 20 to spiking over 100 from time to time. There were myriad changes to my app over the course of the last year since their prior version of my app. I need to nail down which version introduced a change in connection pooling (?) and I was wondering what tools I should use to monitor that.
Any ideas?
I have a website and database in Access, how do i set it up so i can test it in IIS using SQL server?
View 5 Replies View RelatedI 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,

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?
View 7 Replies View RelatedI'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.

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
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?
Any help appreciated
