I've got Initial and Secondary Approver categories. I need to open a cursor to test for the Secondary Approver, if the Cursor is empty I need to pick up the Initial approver. I'm not sure how to test for an empty cursor
--Cursor for the Approvwers
Declare Approve_curs cursor

FROM tblApprovers a
where ((a.AppRole)='S')
FOR READ ONLY
--Open Cursor
OPEN client_curs
FETCH NEXT FROM Approve_curs INTO @P_ID, @text
'I need to test here for an empty Cursor ???
--Start Loop

I have a SSIS package this set to run at a specific time each day. If there are no files for the ForEach tool to work upon...while it doesn't 'fail'...I would like to test for the condition that the enumerator was empty...so that I could send an email message reminding someone to followup and investigate.
What would be the best way to test for that condition?
How is it possible to test at the beginning of a stored procedure if acursor I want to declare already exists? (So I don't cause an error bydeclaring it).ThanksBruno
STATIC Defines a cursor that makes a temporary copy of the data to be used by the cursor. All requests to the cursor are answered from this temporary table in tempdb; therefore, modifications made to base tables are not reflected in the data returned by fetches made to this cursor, and this cursor does not allow modifications
It say's that modifications is not allowed in the static cursor. I have a questions regarding that
Static Cursor declare ll cursor global static for select name, salary from ag open ll fetch from ll
while @@FETCH_STATUS=0 fetch from ll update ag set salary=200 where 1=1
close ll deallocate ll
In "AG" table, "SALARY" was 100 for all the entries. When I run the Cursor, it showed the salary value as "100" correctly.After the cursor was closed, I run the query select * from AG.But the result had updated to salary 200 as given in the cursor. file says modifications is not allowed in the static cursor.But I am able to update the data using static cursor.
Hello,I have a test database with table A containing 10,000 rows and a tableB containing 100,000 rows. Rows in B are "children" of rows in A -each row in A has 10 related rows in B (ie. B has a foreign key to A).Using ODBC I am executing the following loop 10,000 times, expressedbelow in pseudo-code:"select * from A order by a_pk option (fast 1)""fetch from A result set""select * from B where where fk_to_a = 'xxx' order by b_pk option(fast 1)""fetch from B result set" repeated 10 timesIn the above psueod-code 'xxx' is the primary key of the current Arow. NOTE: it is not a mistake that we are repeatedly doing the Aquery and retrieving only the first row.When the queries use fast-forward-only cursors this takes about 2.5minutes. When the queries use dynamic cursors this takes about 1 hour.Does anyone know why the dynamic cursor is killing performance?Because of the SQL Server ODBC driver it is not possible to havenested/multiple fast-forward-only cursors, hence I need to exploreother alternatives.I can only assume that a different query plan is getting constructedfor the dynamic cursor case versus the fast forward only cursor, but Ihave no way of finding out what that query plan is.All help appreciated.Kevin

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

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.
Is it possible to get a list of all the fixes and enhancements that are going into SP1 for SSIS? This will make it alot easier to test seeing as we will know what we are looking for.
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
