Fixing A Slow, Brute Force Set Of SQL Calls
Dec 24, 2003
I've got a huge inefficiency in my code that I'm trying to fix. I’m coding in VB.NET using ASP.NET and an MSSQL 2000 server.
I’m working in a temporary table that has an identical layout as another, non-temporary table in my database. Once I get the temp table how I want it, I need to insert everything from that table into my main table. Before I can do that, however, I need to delete all the records in the main table with certain fields that match a record’s fields in the temporary table.
Right now, I have a method that builds one delete statement per record in the temporary table and then runs those statements on the main table. Since I’m dealing with the order of 50,000 records (at least) here, building and sending those statements to the server takes forever.
Is there a way I can accomplish the same thing without building and sending such a huge SQL call to the server? If so, how would I go about doing that?
Thanks in advance for whatever help you can give,

Hi to all,
Im looking at the sql server log, and I see a strange behavior.
Im getting at least 5 "sa" login attempts from an sepcific IP address.
How can I avoid this, lock that IP or add a delay to 'sa' failed logins?
Thanks so much

In the Application event log I am seeing entries like the
following:
Login failed for user 'sa'. [CLIENT: 60.32.67.85]
Once
every second.
I am assuming this is a brute force password attack, an
ARIN query of the IP address indicates it's from:
Asia Pacific Network Information CentreIs there any way to block this IP from accessing my server?Thanks,Tylerp.s. I tried posting this on MSDN forums, but the site appears to be broken.

It is not uncommon for me to review the event logs of our SQL Server and notice that someone is attempting to figure out the password for one of the SQL user accounts.........especially the "sa" username. But lately our SQL server has to be rebooted to where it is starting to become a nightly thing.
Last night the SQL Server was bombarded with attempted failed connections for 2 hours before it finally gave a blank BSOD. The SQL Server in question is in mixed mode and is a shared server. Strictly using Windows Authentication mode is not an option for us. The server has "beefy" hardware and has all updates and patches.
Sometimes, when I log on the server and notice that an IP address is making such attacks on the server, I put up an IPSEC policy against that IP. But that is not a good solution for reasons I dont think need to be outlined here.
So my question is, what can I do to better protect our SQL Server from these types of attacks? My thought on these attacks is not different than a DDOS that eventually takes the server down.
I have already done TCP/IP Hardening but not sure what else to do.
Thank you all for your replies.

In my product description field, I need to extract the data that looks like
19-3-19 or 0-0-7. Sometimes that pattern is in the data, sometimes not.
I only want those that contain the pattern, of course, but I have no other method of determining whether or not the pattern will be in the description.
I thought I'd found a method that worked, until I encountered descriptions
that had a '-' in it prior to the pattern.
Here's what I have so far, it works for all but the last one.
CREATE TABLE #TMPPROD (
PROD_DESC VARCHAR(60)
)
INSERT INTO #TMPPROD
SELECT '22-4-12 15%SCU'
UNION ALL
SELECT '14-4-8 W/F'
UNION ALL
SELECT 'UFLEXX 17-3-17 2%FE'
UNION ALL
SELECT 'FERT-PEST 19-19-19'
SELECT PROD_DESC, SUBSTRING(PROD_DESC,CHARINDEX('-', PROD_DESC)-CASE WHEN PATINDEX('[0-9]', SUBSTRING(PROD_DESC, CHARINDEX('-', PROD_DESC) - 2,1))<>0 THEN 2
WHEN PATINDEX('[0-9]', SUBSTRING(PROD_DESC, CHARINDEX('-', PROD_DESC) - 1,1))<>0 THEN 1
ELSE 0 END, CHARINDEX('-', SUBSTRING(PROD_DESC,
CHARINDEX('-',PROD_DESC)+1,2))+CASE WHEN PATINDEX('[0-9]', SUBSTRING(PROD_DESC, CHARINDEX('-', PROD_DESC) - 2,1))<>0 THEN 2
WHEN PATINDEX('[0-9]', SUBSTRING(PROD_DESC, CHARINDEX('-', PROD_DESC) - 1,1))<>0 THEN 1
ELSE 0 END+2+CASE WHEN PATINDEX('[0-9]', SUBSTRING(PROD_DESC, CHARINDEX('-', PROD_DESC) +1,2))<>0 THEN 2
WHEN PATINDEX('[0-9]', SUBSTRING(PROD_DESC, CHARINDEX('-', PROD_DESC) - 1,1))<>0 THEN 1
ELSE 0 END) AS 'ANALYSIS'
FROM #TMPPROD
WHERE PROD_DESC LIKE '%-[0-9]%-[0-9]%'
DROP TABLE #TMPPROD
Any pointers on what to try next, or have I severely over-complicated the process - as I am wont to do.
Thanks

Hello,
I restored a huge ReportServer backup on a dev machine and I do not want the subscriptions and their jobs.
I already changed the SMTP server address so emails will go to nowhere.
Now What is the best sequence to get a rid of all subscriptions?
Delete records (or truncate) from the ReportServer.Subscriptions table then delete all the subscriptions jobs or the other way around?
BTY, a centralized management of subscriptions as well as stuffing all these jobs into a folder would be a welcome addition.
Thanks,
Philippe

I have a SQL2000 db that uses NT authentication for the users. All users have access to the public group on the db's and are assigned security inside the application. When I restore the db's to another server (can't do master) the logins seem out of synch. Users who had access to db's no longer did. I realize each user has their own sid. 2 questions - 1 if I dropped all the users and used DTS to import the logins would that be better. 2nd - I thought (couldn't find in BOL there was a sp_fixlogin% sp that could be run that might help me with this.

2 questions, actually:
I am new to database design and a lot of things never made any sense to me regarding relationships and such. I have been working on a very large design that started out well enough, but as tables were added a lot of organization fell by the wayside. Now that I am getting closer to the end, I am finding a lot of places where there should be Foreign keys, maybe some triggers, etc (I have the same data item in 5 different places, when it is deleted in one place it must go from all). Assuming that the datatypes and sizes are identical for the duplicated bits of data, can I go about making FK-PK relationships and such now that there is a lot of stuff in the database, or do I have to start from scratch and rebuild the whole thing.
The other question is much more simple:
How do I make multiple rows "unique". I have a primary key, and an identity column, but I can't add a secong primary key, and Enterprise Manager only lets me make 'int' datatypes identity columns. I have tried the "add constraints" but it asks for an expression and I have no idea what the syntax might be.
Any help is appreciated.

hours wasted what else is new with Micro --- crap try to import an excel into a table, longest field (via vba macro report) is 278 receiving DB field is 4000 get "Truncation error, I must stop I am a piece of s*** program " the only thing you can find on the web is make sure you have SQL server 2005 SP2 install it same thing and g** only knows what other problems I have just created by installing another piece of Microsoft magic generated in India or China by the best technologists making at least $5 and hour
so MVPs when is this rediculous situation going to be fixed ?? oh that's right your answer will be "go to VISTA" which won't fix my problem but will probably help your stock situation
MS owes me (conservatively) 100K ... my current plan is to install Linux get up on MySQL and NEVER deal with SHoddy half built pieces of garbage again
so where is the fix ???
when will we see it (short of buying another bloated piece of ... oh i mean Vista)
an addendum
i am trying to import 25,000 rows with approx 20 columns from Excel
i added a first column with an ID .... if I import whole table it dies on row 1852 for truncation problems
if I empty that column all goes in make other exel get rid of all rows except ID and bad row (contains web addresses eg http://www. blah blah)
import that excel it dies on row 2395 in other words the first offending cell was no problem if it was the 2cnd row instead of the 15th row
try to tell me this is not a random bug .... long live MYSQL

I have an indexed view and i can't get why after "fixing" one of index it became slower then before.
Goal was to switch index to INT column instead of VARCHAR, so the theory looks perfect !!!(?).
I drop index and built new one with same name. Could it be because of Statistics? should I refresh it all ?
The only thing I changed is one of 3 idx:
-- CustTypeCode VARCHAR(10) /* 1,2,3,4,5 */
-- CustTypeID INT /* 1,2,3,4,5 */
-- index Before:
CREATE NONCLUSTERED INDEX [IdxLookTypeCode] ON [dbMacros].[vw_Lookup_Customer]
([CustTypeCode] ASC)
-- index After:
CREATE NONCLUSTERED INDEX [IdxLookTypeCode] ON [dbMacros].[vw_Lookup_Customer]
([CustTypeID] ASC)
-- usage before:
SELECT C1, C2, FROM vw_Lookup_Customer WITH (NOXPAND)
WHERE CustTypeCode = 2
-- usage after
SELECT C1, C2, FROM vw_Lookup_Customer WITH (NOXPAND)
WHERE CustTypeID = 2

Hi all,While using ACCESS and asp for years, I have just had to move my site onto a new server and the opportunity to move my 50MB access DB to msSQL was too good an opportunity to pass up! I used the Migration tools from MS and the data migrated nicely, I can do everything that I used to be able to do on the forum, except when a new user signs up or a member tries to edit their profile, the following error message comes up:
Microsoft OLE DB Provider for ODBC Drivers error '80040e14'
[Microsoft][ODBC SQL Server Driver][SQL Server]The UPDATE statement conflicted with the CHECK constraint "SSMA_CC$PORTAL_MEMBERS$M_ICQ$disallow_zero_length". The conflict occurred in database "DATABASENAME", table "dbo.PORTAL_MEMBERS", column 'M_ICQ'.
I have checked the database and the dbo.PORTAL_MEMBERS table and except for the autoincrement number, uname and pwrd, everything else is set to accept nulls.
I also went though and filled in everything on the form then I could update.
the same error applies when signing up - the only difference is the name of the table
I then tried to change the data straight in the table by opening it in Server Management Studio Express and got the same error if I did not fill in everything. This tells me that it is not the code, much to my relief!
So I am figuring that there is something somewhere in the DB that I have to change? could someone point me in the right direction - and as I am VERY NEW to this database system, and do not know my way around (it took me about 10 minutes to figure out how to open a table! *LOL*) very clear instructions would be appreciated.
Thank you for your time :-)

Hi folks,
I used a non-printing character (hex 97) in one of my derived column transformations which made my data flow task comopnents disappear, and throw the error during execution:
"Warning: The DataFlow task has no components. Add components or remove the task."
In order to fix the package, I thought I could open the .dtsx file in code/raw form, find the misbehaving character, remove it, and I'd be good to go.
But I can't figure out how to read the .dtsx code to find the character (despite my best efforts with a hex editor).
Anyone have any ideas? Fixing this package could save me days of rework...
Thanks a lot everyone.
Ted

Hi.
I’m having a conceptual problem with tracking sales vs. call center calls.
Each record in the fact table represents a call to the call center.
In this record are various facts and foreign keys that map to marketing campaigns, etc.
The product sold ID is NULL on no sale, and filled in for a sale.
When creating MDX to retrieve data by campaign, for example, to track the number of calls for a campaign vs. it’s sales, that works fine (because there’s a column labeled sale that’s either 0 or 1 for the sale and I just sum it). This way I get the conversion percentage of calls to sales.
But when creating MDX to track the product sold, as soon as I do a crossjoin on campaign and products sold, for example, I lose the total calls- the number of calls is the same as the sales (similar results as a SQL join). Am I doing something wrong or is it conceptually impossible to track this type of metric down to the product when there are NULLs in the fact table? I’ve tried converting the nulls to a NONE category, but that doesn’t stop the crossjoin from not giving me the desired results, plus I then have to filter out NONE as a product.
Is that why a lot of sample warehouses have a separate sales cube?
Thank you,
Richard

Hi group,
I've got a performance issue.
Here's in global what the sp (Let's call it SP_A) does.
Step 1 Call a different SP (Lets call it SP_B) and store the output in a variable
Step 2 SP_B runs a select statement that returns 1 value
Step 3 SP_A uses this value as a parameter in a select statement.
Step 4 The result of the SP_A is the result of the select statement (744 rows (always))
All tables used in SP_A and SP_B are temp tables.
Total performance of SP_A is between 0.090 and 0.140 seconds.
The problem is that this SP is called 180 times from outside SQL server. That means that the total processing time is somewhere between 21 and 25 seconds.
When I move the entire processing to within SQL server I gain only 2 seconds. So I lose 2 seconds in connecting to the database 180 times.
Can someone give me some pointers on where to look for performance wins?
If you like I can add the SP's
Regards,
Sander

I have an old app that I'm trying to recode and improve performance.
From the start it makes three seperate calls to a db, checks to see if the record exists, if it doesn't it adds it, then takes the data from all three and inserts it into a final call.
Here is a quick example of the script
Select * from table1 where id = " & tempVariable
If Not RS.EOF Then
strTable1 = RS("SomeRec")
Else
RS.ADDNEW
RS("SomeRec") = tempRec1
RS.UPDATE
RS.Requery
strTable1 = RS("SomeRec")
End If
RS.CLOSE
Select * from table2 where id =2
If Not RS.EOF Then
strTable2 = RS("SomeRec")
Else
RS.ADDNEW
RS("SomeRec") = tempRec2
RS.UPDATE
RS.Requery
strTable2 = RS("SomeRec")
End If
RS.CLOSE
Select * from table3 where id =3
If Not RS.EOF Then
strTable3 = RS("SomeRec")
Else
RS.ADDNEW
RS("SomeRec") = tempRec3
RS.UPDATE
RS.Requery
strTable3 = RS("SomeRec")
End If
RS.CLOSE
INSERT INTO Table4 (Table1, Table2, Table3) VALUES ('" & strTable1 & "', '" & strTable2 & "', '" & strTable3 & "'
These is probably an easy solution however I don't know where to start. Any help or ideas will be greatly appreciated.
Thanks
-Scott

hi all.
when i worked with oracle before, it was very common to call a function from inside a s.procedure.
now, someone talled me that in sqlserver this is not a best performance approach, and i should try to avoid this.
is this true?

My Problem is that I don€™t know really what does a call means.
We got a SQL Standard Edition.
Can I install as many instances I want in a Server?
How many users can access the Server at the same time?
If I use SQL authentication, and two users use this logging information, how many calls do they made? 2 one per each user (PC) or just 1 one per logging.
If I have a client / server application, and the server access the SQL Server using SQL authentication. Can I have unlimited number of clients?

Hi,
I'd like to keep state between calls to a UDF (mainly for caching purposes). I can shove an object into the appdomain using SetData and read it using GetData, but that requires the assembly to be set to UNSAFE. I'm confident I can secure the DB and the assembly fairly well, but I like defense in depth, and if there's another way to save state between calls to a UDF, I would prefer those.
Is there another way to store state between calls to a UDF, without putting data into DB tables or using things that will require the assembly to have such a wide permission set?
Thanks,
Alex

Suppose my database has 3 table A though C and I need to get the number of records in each. I could do it as individual selects like
SELECT 'A' AS 'Table', COUNT(*) AS 'Count' FROM A
SELECT 'B' AS 'Table', COUNT(*) AS 'Count' FROM B
SELECT 'C' AS 'Table', COUNT(*) AS 'Count' FROM C
or
SELECT 'A' AS 'Table', COUNT(*) AS 'Count' FROM A
UNION
SELECT 'B' AS 'Table', COUNT(*) AS 'Count' FROM B
UNION
SELECT 'C' AS 'Table', COUNT(*) AS 'Count' FROM C
Is there any problem in unioning statements like these? In reality there were over a hundred tables and the TSQL was generated by looping through SYSOBJECTS. I eventually used the first construct as the XML was simpler to generate.

I need to develope a stored procedure (eventually called by a trigger) that creates a record in an event table for all the descendants of a drawing. There are 3 tables involved as example tables shown below:
DwgTable
DwgID (integer)--drawing record identifier
PrntDwgID (integer)--parent drawing record identifier (a previously defined DwgID from this table)
DwgEventTable
DwgEventID (integer)--record identifier
DwgID (integer)--value from DwgTable
EventID (integer)--value from EventTable
EventTable
EventID
There are other fields in two of the tables and only the fields shown in the DwgEventTable, but only the fields shown are required for adding a record in the DwgEventTable for a new event in the EventTable. The problem is identifying all the DwgID's of the descendant of the DwgID where the EventID occurred. There may be 0 to N descendants in 0 to N generations. I need to add a record for the original DwgID and all the descendant DwgID's in the DwgEventTable for the event identified by EventID.
I could do this from the client side, but a better place would be from the server side. I need some clue(s) on how to start coding a recursive stored procedure in SQL Server 2005. From what I have read, you cannot create a managed code procedure that appends or updates records--if managed code can add/modify records then I can do the above with managed code procedure.
Any Suggestions?

I am running the code below in a sql job. Exec (@SQL) errors every time but after 4 failures the job fails instead of trying @MaxRetries times. Any idea on why this is happening?
Set @RetryCounter = 0
WHILE (@RetryCounter < @MaxRetries)
Begin
SELECT @error_value = 0
Exec (@SQL)
SELECT @error_value = @@ERROR
If @error_value = 0
Set @RetryCounter = @MaxRetries
Else
Begin
WAITFOR DELAY '00:05:00'
Set @RetryCounter = @RetryCounter + 1
End
End

I have several SSIS Packages which are called by few different applications. I need to make packages Mutually Exclusive, so that If one is running; calls to any other Package should be put on wait till the running one has finished its execution.
What are the best ways to do this ?
I would sincerely appreciate inputs in this.

is it true that I will not be able to use the returned value from an sp that is called on every row from an oledb command transformation? I see all kinds of complaints on the web but cant determine if this would be a waste of time. I'd like to append the returned value (which is calculated and cannot be joined in the buffer) to the data on its way out of the transformation.

Hi all
I am using internal activation on a queue to process the messages, should an error be encountered I call stored procedure A in the same database to log the error. Part of the processing in stored procedure A is a call to stored procedure B in another database (on the same server), however I have not been able to get this call to B to work. Currently I get the error "The server principal XXXXXX is not able to access the database YYYYYYY under the current security context".
I have tried various combinations (too many to remember) of database owners, roles and permissions as well as EXECUTE AS on both A and B and the Queue but none seem to work. Can anyone give me simple example of a setup which would allow this cross database call to work?
Thanks
Ian

I am wondering if it is at all possible to keep an object in memory between calls to a SqlFunction or SqlProcedure.
Every time a row is inserted in to a table, i need to do some processing on the data. The processing becomes many times faster if I can do some preprocessing (the preprocessing is independent of the data inserted into the table). So basically, I want to save the result of the preprocessing, only do it one time, and save the result in a object in memory. Is this at all possible?
Regards, Egil.
