An Interesting Idea...
Jun 23, 2007
Having no more experience than reading books online, here is an interesting idea I would like to run by you guys and you can let me know if it is feasible or tell me I need to put the crack pipe down...
We are going to increase the number of disks in our SAN, and I was speaking with the SAN administrator and he mentioned the shuffling of logical drives to match the new space. He said he is going to have to go through quite a few combinations/permutations on figuring out the best configuration for what data goes on the old vs. new to get the optimal space.
Is this something that can be modeled out? I can write something that recursively figures it out, but why not explore fun ideas with tools that may be able to do it?
Thank you in advance,
John Hennesey

Below is the statement given in MicroSoft SQL Server migration documentation :
"When a view is defined with an outer join and is queried with a qualification on a column from the inner table of the outer join, the results from SQL Server and Oracle can differ. In most cases, Oracle views are easily translated into SQL Server views"
Please can anyone explain the above with some examples. I don't find such a 'CREATE VIEW' statement existsing in two DBs, which results in different result set. Am I wrong ?
Thanks,
Sam

Another tech was having the same problem with his sp which he also made into a macro. He was having the same problem as I was, he thought since he made the user the dbo owner that he woud have no problems...but since hes the one who created the db and the stored procedures when the user tried to access it he got that same error message. It went away after he went into the Enterprise manager and in the properties of the stored procedure under permission he gave the user EXEC permissions...And WAAALLLAAA problem solved :):):):)

Anyone else experience this? A developer just finished complaining about the performance of one of our databases. Well, he sent me the query and I couldn't understand why it was such a dog. Anyways I rewrote it. The execution plan is totally different between the two. I had no idea specifying the join made such a difference. First sql executed in 7 minutes that 2nd took 1 second. SELECT dbo.contract_co.producer_num_id, contract_co_statusFROM dbo.contract_co, dbo.v_contract_co_statusWHERE ( dbo.v_contract_co_status.contract_co_id = dbo.contract_co.contract_co_id ) AND contract_co_status = 'Pending' OR ( contract_co_status = 'Active' and effective_date > '1/1/2004' )SELECT dbo.contract_co.producer_num_id, contract_co_statusFROM dbo.contract_co INNER JOIN dbo.v_contract_co_status ON dbo.contract_co.contract_co_id = dbo.v_contract_co_status.contract_co_idWHERE contract_co_status = 'Pending' OR ( contract_co_status = 'Active' and effective_date > '1/1/2004' )

Hi all,
I am new to the DTS game - or at least to trying to do anything other than transfer rows between databases with identical structures.
I now need to create a far more complex DTS package to transfer data between an SQL Server database (I am using SQL Server 7.0) and an Oracle database. I have no trouble in making the connections and performing simple DTS's beween the two.
However, my current task is more complicated.
Problem 1:
In one database I would store fifty values as 5 five records each containing 10 values (i.e. has ten fields). However, in the other database these fifty values would all be stored as one record (i.e. one row with 50 fields). How could I go about creating a DTS to transfer this information?
Problem 2:
These values should only be transfered if certain conditions are met in an another unrelated table. For example, a flag in another table indicating that transfer of the said values should occur.
Any help with either of these problems would be much appraciated.
Thanks in advance,
Ross

If anybody can suggest the most efficient way to "page" the output from a big and wide table (about 7000000 records) in order to display on the web in the user requested sort order. Sort order could be on at least 7 different columns from 50 of returned.
I need to find a solution to move to the next and previous page.
Any Idea?

what if I took this trigger and based it on a view rather then a table
CREATE TRIGGER TerminationUpdateTrigger ON EmployeeGamingLicense
FOR UPDATE
AS
INSERT INTO TERMINATION(Status,[TM #],LastName, FirstName, [SocialSecurityNumber], DateHired, Title)
SELECT STATUS, [TM#], LASTNAME, FIRSTNAME, [SSN#], HIREDATE, JOBTITLE
FROM Inserted
WHERE STATUS = 'TERMINATED'
CREATE VIEW dbo.Update_Terminations
AS
SELECT STATUS, TM#, LASTNAME, FIRSTNAME, SSN#, HIREDATE,
JOBTITLE
FROM dbo.EmployeeGamingLicense
WHERE (STATUS = N'TERMINATED')
Base the Trigger on this View rather then on the Table itself????

Hi I'm new to sql and it would be great if someone could give some idea on how to do the following
This is the relational model:
Department(DeptNum, Descrip, Instname, DeptName, State, Postcode)
Academic(AcNum, DeptNum, FamName, GiveName, Initials, Title)
Paper(PaNum, Title)
Author(PaNum, AcNum)
Field(FieldNum, ID, Title)
Interest(FieldNum, AcNum, Descrip)
The question is :-
Which academics have the largest number of fields of interests? Return their academic number,
given name, family name, institution and total number of fields they are interested in. Your must use a
subquery in the sense that you must use 2 sql statements and use any of the following to connect both:-
1)Exists
2)Not exists
3)IN

I have a table call CLIENTE and another table call ENDERECO where the CLIENTE table has the FOREIGN KEY of the ENDERECO table.
When I try INSERT COMMAND in C# this message is show.
The instruction INSERT conflicted with a constraint of FOREIGN FUNDAMENTAL "FK_CLIENTE_ENDERECO." The conflict happened in the database "E:ARQUIVOS DE PROGRAMASMICROSOFT SQL SERVERMSSQL.1MSSQLDATALINETEC.MDF", table "dbo.I ADDRESS", column 'IDENDERECO.'
The instruction was concluded.
I am a "little" lost.

Hi all,
I have a system in place currently that both a local and a live database, currently the sales database is kept in line with a home grown "syncronise" script that controls keeping the two tables (live and local) in sync with the use of Local and Remote ID'sFor example;Table "Sales"ID - IntRemoteID - IntVarious Data fieldsThe 'Live' System writes new records using the RemoteID field, whilst the local inserts new records using the ID field. The Sync script copies the data up/down and assigns the corresponding RemoteID/ID's to the records as they are copied accordingly.Its been decided that this process must change, in favor of Two Way Replication. I have been tasked with finding the solution to the safe handling of ID's as theres a danger that two people can be writing a record (one live, one local) and possibly create the same ID's - i know that replication has its own ID's and could probably manage this well on its own, but these 'Internal' ID's have to be unique due to business rules.So i have been considering two possibilities to address this problem,1. Staggering the ID's - for instance Live ID's begin at 1,000,001 and local ID's begin at 1.2. Having a controlling ID table which provides the next IDBoth options have their advantages and disadvantages, with option 1 we will run into a problem later when the local ID's reach the 1 million mark (a few years away, i admit) and option 2 will need careful locking/transactional code to ensure the same ID isnt given twice.Does anyone have experience with this kind of issue? or could suggest an alternative approach to this problem? Thanks in advance!

We've had an interesting server issue here since about the start of the year, where the dual processor Netfinity server we've been running SQL 7 on has been holding steady at almost exactly 50% CPU utilization, give or take about 5%-10%. Disk utilization in all areas is relatively low. In fact, the server will do this right after a fresh reboot, with no users accessing. The really interesting part is that a graph of the two processors mirror each other. When the utilization of one goes up, the other goes down, almost perfectly. The two processors are the same speed, but their firmware build is different. IBM says it's not a problem. What say ye?

If Query1 gives 1 row output as:
customer_id
1234
-------------------
Query2 gives 1 row output as:
product_id
8970
-------------------
How do we get the above results as a single result set of 2 columns side by side? as follows:
customer_id product_id
1234 8970
Is that possible in a single select statement??
Query1 and Query2 both are select statements on the same table with different where clauses.
Sheila.

Hi ! I am facing an interesting problem for one of my databases. When I double click on a particular table in Enterprise Manager, the Manage Tables window shows me only one or two fields from the table. (it does not show me all the fields). When I run sp_help <tablename> in isql, all the information is displayed. Why is there such inconsistency. It happens only on one particular database. I have run DBCC commands but still no help. Does anyone have any ideas on this. Thankx,

We're having to work with some legacy data. The tables in the so-called database seem to have way more nulls than actual data. One table appears to have around 100 or more columns in it. It has close to 40,000 rows.
This Db has pretty much 0 normalization present.
IOW, your worst nightmare.
Is there a way we could run a query that would return the total number cells inthat contain NULL and another that could return the total number of data-bearing cells so we could come up with a % or a ratio.

Hi Folks,
This is a create table statement in DB2 z/ODS and OS/390 ( mainframe versions ) :
create table test(sno int) IN DATABASE database1 AUDIT NONE DATA CAPTURE NONE
This will create a table in the named database 'database1'.
1) In SQL Server, is there any equivalent for this 'IN DATABASE' syntax in DB2 ?
2) 'Data capture none' will not store any extra info about the data replication in the log files. Is there any eqiuivalent for this in SQL Server ?
Thanks,
Sam

Imagine a table in Microsoft Sql Server 2000 named Pictures with threefields. A primary key ID(int), a Name(nvarchar) and a Picture(image)field.Lets put some records into the table. The first two fields as expectedwould take an int and a string. The third field is of type image.Instead of putting a bitmap in this field lets place an xml documentthat has been streamed into a byte array. The xml document woulddescribe the Picture using say lines. If the picture was that of asquare we would have four lines in the xml document. You could think ofthe xml document as something similar to vector graphics but thedetails are not relevant. The important fact is that the contents ofthe image field is NOT a bitmap but a binary stream of an xml document.Now imagine we have a reporting tool like Crystal Reports that can beused to report on this database table. Imagine we create a report byusing the three fields mentioned above. As far as Crystal is concernedthe first field is an int, the second a string and the third an image.If our table had ten records and we preview the report we like to see10 entries each consisting of an ID, Name and a Picture.This can only happen if the image field contains a Bitmap, but asmentioned above the field contains an xml document.Now my question...Can we write something in SQL Server 2000 (not 2005) to sit between thetable and Crystal Reports so to convert the XML document to a bitmap.The restriction is that we cannot use anything but sql server itself.The client in the above case has been Crystal Reports but it could beanything.I know SQL Server 2005 supports C# with access to the .NET frameworkwithin the database. Unfortunately, I am not using SQL server 2005.Some people have suggested the use of User Defined Functions and TSQL.I like to know from the more experienced SQL Server people if what I amtrying to achieve is possible. Maybe it has not been done but is itpossible?Any suggestions would be greatly appreciated...Many Regards

Hi All,
When I wanted to see ONLY today€™s records on the sql server, it took 5 minutes.
When I wanted to see records including today€™s records on the sql server, no problem. (19 Sep. is a past date which is working properly)
It is very interesting it takes 5 minutes to sort the lastday there is nothing wrong with the other days.
I ran DBCC INDEXDEFRAG method but no change anything.
I am wondering about something, everyday at 22:00 pm we are getting backup. Is this process creating a difference between before getting the back up and after got the backups?
It is really interesting issue. I do not know what I can say. It seems there is an issue with today€™s records. May be there are some locks on the today€™s records. I do not know. Why does not cause any issue for old dates but for current day ?
SELECT DISTINCT CallIDChar, ANI, DNIS, CallerName, AgentName, CallQueue, AgentID, CallType, CallStartTimeStamp, CallEndTimeStamp, CallDuration
FROM (SELECT MAINTBL.*, DRTTABLE.CallDuration AS CallDuration
FROM CallInfo AS MAINTBL
JOIN ( SELECT CallID, DateDiff(second, min(CallStartTimeStamp), max(CallEndTimeStamp)) as CallDuration
FROM CallInfo
GROUP BY CallID
) AS DRTTABLE ON MAINTBL.CallID=DRTTABLE.CallID
) as CallInfo
WHERE CallIDChar = CallIDChar
AND (CallStartTimeStamp >= '2007-09-20T00:00:00')
AND (CallStartTimeStamp <= '2007-09-20T23:59:59')
What can be reason for this issue and how can I solve it ?

Lets say I have to insert 60,000 or so records into SQL Server from another data source using the sqlTransaction class.
However if at any point an error should occur I would like to roll back any changes.
Would a transaction be a bad idea when dealing with this many records?
Thanks for any advice.

Hi guysWe have a following problem. For security reasons in each table in ourDB we have addition field which is calculated as hash value of allcolumns in particular row.Every time when some field in particular row is changed we create andcall select query from our application to obtain all fields for thisrow and then re-calculate and update the hash value again.Obviously such approach is very ineffective, the alternative is tocreate trigger on update event and then execute stored procedure whichwill re-calculate and update the hash value. The problem with thisapproach is that end user could then change the date in the tables andthen run this store procedure to adjust hash value.We are looking for some solution that could speed up the hash valueupdating without allowing authorized user to do itThanks in advance,Leon

Hello,
In the code SqlParameter dtDate = new SqlParameter("@date",SqlDbType.SmallDateTime,4);
dtDate.Value=Convert.ToDateTime(Session["date"].ToString());
cmd.Parameters.Add(dtDate);where the @date parameter is defined as a SMALLDATETIME inside a stored procedure, I cannot use a function such as "Convert.ToSmallDateTime" and it seems a conversion from DateTime to SmallDateTime takes place anywhere within the code. Eventually it works but I wonder if everything's ok with this code. Is there anything wrong about it? Thanks

I have an interesting request.
I would like to take a table such as:
date value
----- -----
1/1/01 10.5
1/2/01 9.3
1/3/01 11.5
1/4/01 4.7
1/5/01 3.2
and calculate an average for each record, based on its own value AND the following two values. In other words, for the first record, I would take
sum(10.5 + 9.3 + 11.5)/3 and put this into a third column in my table. I would then do the same for the next record: sum(9.3 + 11.5 + 4.7)/3.
Thanks in advance!
