Hi everybody
I want to know in the real world, what RDBMS is used for keeping people's accounts in official Banks( institution for saving and borrowing money) ? do they use SQL-Server , ORACLE or some thing else?
Thanks in advance.
Regards.
Does anyone out there know if you can take a user like this domain1Username and without dropping it and recreating change it to domain2username. I am using Sql 7.
Thanks in advance

So, I kinda taught myself sql on the net in a couple of weeks... I've been practicing commands and what not with a database with a company I work with. Here's what I need some help with:
I'm creating a batch file that will connect to the sql server, and input a .sql in the batch file which launches the sql script to check to see if a store's data has come in or not, and if it hasn't, to launch the job to process that store. Now, after it launches the job, the only step for the job is to process what it can before it fails or completes, and most of the time it fails after 1-10 minutes. A big a variance. So my question is, how do I make it so that the script being called, waits for the job to finish before proceeding to the next command which checks a different store and launches another script?
If you want the script, I'll mod out some of the actual names for security purposes and post it for you guys. Any help is appreciated, and I've searched and hacked Google to get an answer, but nothing, so I decided to post this. Thanks!
Whilst digging about in the systables I noticed 2 curious things:
When creating an application that returned all tables, columns and fields I had to use sys.systables, and when returning the information from this view, I received two identical columns 1. myColumn of type sysname and 2. myColumn of type varchar. The point being, what is this column for, and why is it there, as it was quite annoying to note it when returning the dataset in my app.
My other point is, while checking out what I could do with sysname, I noted the xml type has a capacity of -1, whereas all other data types have a capacity between 2-8000. Could someone clarify this for me, as it seems a single xml document could be inserted upto 2gb.
Regards.
How can I write a query to return non distinct results?
View 3 Replies View RelatedSo I have a person who is adamant in tell me that SQL Server does not run on windows XP.
Now, I have already done all the research on this (i.e. sql server 2000 product page / requirements) and know the answer, but they insist on asking the question, so here it is .....
'Will SQL Server run on Windows XP'
A simple YES or NO will suffice; however, if you want to explain the answer (if it requires one ;) ), please feel free.
Can someone try and explain to me how a sql query can run fine and return data, yet when I try to run it in dtswizard, while the "preview" view shows the data, actually running it returns zero rows?
This is on SQL2005 express and since I can't get dtsrun or dtexec to work, I'm using auto-it to simulate my actually stepping through the process. Very kludgy, but "when all you've got is a hammer...."
Dear GroupSomething that I ever found quite difficult was finding a bug in ascript e.g. in a stp#ored procedure as often it would indicate theerror in a completely different line in which the error is actuallylocated. Take the following scriptALTER PROCEDURE [dbo].[fra_UpdateCompany]@CompanyID int, @CompanyName varchar(50), @Status int, @TelNovarchar(50), @FaxNo varchar(50), @Email varchar(50), @Web varchar(50),@OfficeType int, @Comment varchar(512)ASDECLARE@CommentOrg varchar(512)IF (LEN(@CompanyName) < 1) BEGIN SET @CompanyName = NULL ENDIF (LEN(@TelNo) < 1) BEGIN SET @TelNo = NULL ENDIF (LEN(@FaxNo) < 1) BEGIN SET @FaxNo = NULL ENDIF (LEN(@Email) < 1) BEGIN SET @Email = NULL ENDIF (LEN(@Web) < 1) BEGIN SET @Web = NULL ENDIF (LEN(@Comment) < 1) BEGIN SET @Comment = NULL ENDSET @CommentOrg = (SELECT Comment from fra_company WHERE CompanyID =@CompanyID)SET @Comment = (@Comment + '' + @CommentOrg)-- UPDATE COMPANYUPDATE fra_company SET CompanyName = @CompanyName, Status = @Status,TelNo = @TelNo, FaxNo = @FaxNo, Email = @Email, Web=@Web, OfficeType =@OfficeType, Comment = LTRIM(@Comment) WHERE CompanyID = @CompanyIDIt throws an error in Line 17 IF (LEN(@TelNo) < 1) BEGIN SET @TelNo =NULL END when the error is actually in line 23: SET @CommentOrg =(SELECT Comment from fra_company WHERE CompanyID = @CompanyID)ErrorMsg:Msg 137, Level 15, State 2, Procedure fra_UpdateCompany, Line 17Must declare the scalar variable "@ContactID".Why is that? I had hoped that it had improved from SQL 7.0 to 2005 butit's still the same vague thing.Thanks for sharing your expertise and wisdom on this,Martin

Dear group,if someone could give me an idea what is going on in one of ourdatabases, this would really really be helpful.We have two tables with around 2 / 3 million rows. These tables have nokey and no ID. (This major design flaw will be overcome in some laterversion of the application-software working on this DB but right now ihave to live with this).Now for the funny bit1) I open one window in the Query-Analyzer and write some code likeBegin transaction INSERT INTO TABLE COMMIT2) in another window i write "SELECT COUNT(*) from TABLE"If I perform the insert then afterwards select count(*) the row-countis incremented by two whereas the Insert-Statement said "1 row(s)modified.DBCC gives no errors.DBCC gives amount of rows 2 million rowsSelect count(*) on the same table gives 3 million rowsExporting the data, truncating the table re-importing data gives noresult, right now the DTS-status is 203 and the machine is "thinking".Is there any possibility to check the "integrity" of the table?This problem is on the production machine, but right now i am workingon a copy so it was propagated with backup / restore-mechanism.Any hint would be very helpfulThanks and GreetingsUli

IF [TestColumn] on the Select is varchar, then error occurs and say:"Conversion failed when converting for the varchar value 'A001' to data type int"
Hi,I have been running some queries against a table in a my database andhave noted an odd (at least it seems odd to me) performance issue.The table has approximately 5 million rows and includes the followingcolumns:DocID (INTEGER, PRIMARY KEY, CLUSTERED)IsRecord (INTEGER, NONCLUSTERED)Title (VARCHAR(255), NONCLUSTERED)If I issue the following query:SELECT DocID, IsRecord FROM DocTable WHERE Title LIKE '%process%'it takes about 23 seconds to return the 481 hits.The execution plan shows a non-clustered index scan being performed onthe Title index (returning 481 rows) and a non-clustered index scan onthe IsRecord index (returning 4.9 million rows). These are then mergedin a hash match/inner join operation.The Title index scan has an estimated row size of 41 and an I/O costof 9.82 (cost is 27%). The IsRecord index scan has an estimated rowsize of 33 and an I/O cost of 6.32 (cost is 21%). The Hash Matchaccounts for a further 52% of the cose with the SELECT at the head ofthe plan listed as 0% cost.If I issue the following query:SELECT DocID, Title FROM DocTable WHERE Title LIKE '%process%'it takes about 12 seconds to return the 481 hits and consists solelyof a non-clustered index scan of the Title Index.Again the Title index scan has an estimated row size of 41 and an I/Ocost of 9.82 ans it's cost is listed as 78%. The SELECT at the head ofthe plan is attributed the other 22% of the cost.All this is fine, however when I issue the following query:SELECT DocID, Title, IsRecord FROM DocTable WHERE Title LIKE'%process%'it takes 1 minute 50 seconds to run the query. The execution plansshows that a clustered index scan is occurring and this accounts for96% of the cost. The estimated row size is 463 and the I/O cost is111.What on earth is going on here. I can understand the need to scan theTitle index because of the wildcards, but why on earth would the queryperform a scan of the clustered (primary key) index? And what is goingon with the row size and I/O cost?All the indexes and statistics are up to date, so I am at a completeloss to explain what is going on here. Can anyone explain why the 3rdquery is so much slower (and possibly suggest a way to improve theperformance)/ThanksPaul MateerMeridio LimtedI am at a complete loss to explain what is happening here,
View 3 Replies View RelatedHi all,
Looking at BOL for temp tables help, I discover that a local temp table (I want to only have life within my stored proc) SHOULD be visible to all (child) stored procs called by the papa stored proc.
However, the following code works just peachy when I use a GLOBAL temp table (i.e., ##MyTempTbl) but fails when I use a local temp table (i.e., #MyTempTable). Through trial and error, and careful weeding efforts, I know that the error I get on the local version is coming from the xp_sendmail call. The error I get is: ODBC error 208 (42S02) Invalid object name '#MyTempTbl'.
Here is the code that works:SET NOCOUNT ON
CREATE TABLE ##MyTempTbl (SeqNo int identity, MyWords varchar(1000))
INSERT ##MyTempTbl values ('Put your long message here.')
INSERT ##MyTempTbl values ('Put your second long message here.')
INSERT ##MyTempTbl values ('put your really, really LONG message (yeah, every guy says his message is the longest...whatever!')
DECLARE @cmd varchar(256)
DECLARE @LargestEventSize int
DECLARE @Width int, @Msg varchar(128)
SELECT @LargestEventSize = Max(Len(MyWords))
FROM ##MyTempTbl
SET @cmd = 'SELECT Cast(MyWords AS varchar(' +
CONVERT(varchar(5), @LargestEventSize) +
')) FROM ##MyTempTbl order by SeqNo'
SET @Width = @LargestEventSize + 1
SET @Msg = 'Here is the junk you asked about' + CHAR(13) + '----------------------------'
EXECUTE Master.dbo.xp_sendmail
'YoMama@WhoKnows.com',
@query = @cmd,
@no_header= 'TRUE',
@width = @Width,
@dbuse = 'MyDB',
@subject='none of your darn business',
@message= @Msg
DROP TABLE ##MyTempTbl
The only thing I change to make it fail is the table name, change it from ##MyTempTbl to #MyTempTbl, and it dashes the email hopes of the stored procedure upon the jagged rocks of electronic despair.
Any insight anyone? Or is BOL just full of...well..."stuff"?
