I'm using a VB6 application to access data from an SQL Server 2000 database. There are a few things I would like to do:
1. Get the number of tables in the database
2. Automatically begin reading data from each table in the database. Is it possible to write some code that will cause the application to start on first table retrieve all the data, then move to next table (similar to moving to next row)?
Thanks,
Joey

Hi ,,
How to write the Sql Query to return the next generated Identity from the Sql server database.
Hi
Please help! I'm really stuck. I have a table (AssessorAllocations) that stores the data of students who have submitted assessments for marking by an Assessor. Each time an assessment is submitted by a student my program must determine which Assessor has the smallest workload and then assign the current assessment to that Assessor. My problem is how do I determine which Assessor has the smallest number of assessments assigned to him/her.
The table columns are:
AssessorRegistrationNo
LearnerRegistrationNo
QualficationName
SubjectName
AssessmentName
DateAssigned
Marked
DateMarked
Price
So I'm looking for something like this:
Select AssessorRegistrationNo from AssessorAllocations where {Select the Assessor who has the smallest number of AssessmentNames assigned to him/her where Marked='0' and DateAssigned<>''}
Thanks

Hi
I've created a sproc in SQL2000 that returns a dataset from a temp table & the number of records it's returning as an output parameter, although I can't seem to retrieve the value it's returning in asp.net although I get the dataset ok.
This is my sproc
create procedure return_data_and_value
@return int output
as
set nocount on
...
...
select * from #Table
select @return = count(*) from #Table
drop table #Table
go
This is asp.net code
Dim nRecords as Int32
Dim cmd As SqlCommand = New SqlCommand("return_data_and_value", conn)
cmd.CommandType = CommandType.StoredProcedure
Dim prm As SqlParameter = New SqlParameter("@return", SqlDbType.Int)
prm.Direction = ParameterDirection.Output
cmd.Parameters.Add(prm)
conn.Open()
dr = cmd.ExecuteReader
nRecords = convert.int32(cmd.parameters(@return).value)
conn.close

Hello people,I might sound a little bit crazy, but is there any possibility that youcan incorporate 4^15 (1,073,741,824) tables into a SQL Database?I mean, is it possible at all? There might be a question of whereanyone would want so many tables, but i'm a bioinformatics guy and I'mtrying to deal with genomic sequences and was coming up with a newalgorithm, where the only limit is the number of tables I can put intoa Database.So, can you please advise if its possible to put in so many tables intoa SQL database? Or is the Bekerley DB better?
View 3 Replies View RelatedI have two tables and I want to return data from both. Currently my select statement is returning just 1 child record for each parent record and I want to return all child records that match the parent record.
Here's a sample of my tables/data/etc.
t1
------------
speciesid | species
1 | Mammals
2 | Rodents
3 | Reptiles
t2
---------
animalid | animal
3 | Skink
3 | Iguana
3 | Rattlesnake
2 | Meerkat
1 | Hippo
1 | Elk
What I want to do is pull up a list of all the species and under each list all the animals currently listed under that species.
So the result I want should look like:
Mammals (Hippo, Elk)
Reptiles (Skink, Iguana, Rattlesnake)
Rodents (Meerkat)
so currently I have:
SELECT A.animalid, S.speciesid, A.animal, S.species from t2 as A, t1 as S where S.speciesid=A.animalid order by species
this works great, it's just that it only returns one animal instead of all of the animals. Any help would be appreciated.
We have an archive table which keeps each instance of a sales order that was archived under a "Verion No" field. Each time the sales order is archived it is entered into the archive tables (Sales Header Archive, Sales Line Archive). What I am trying to do is write a query to return all sales orders but only the most recent archived version.
For example this table layout is similar to what I am working with. Version No, Order No and Customer No. are the keys between the Header and Line tables, Customer Name column in the output is from only the Sales Header Archive table
SALES LINE ARCHIVE TABLE
Version No - Order No. - Customer No -----> (other columns)
1 s-5 1000
2 s-5 1000
1 s-6 2000
1 s-7 3000
2 s-7 3000
3 s-7 3000
1 s-8 4000
1 s-9 2000
2 s-9 2000
Here is what I need to output to show:
RESULTS OF JOINED TABLES
Version No - Order No - Customer No - Customer Name ---> (other columns)
2 s-5 1000 Something, Inc.
1 s-6 2000 Acme
3 s-7 3000 Company, LLC
1 s-8 4000 Blah & Associates
2 s-9 2000 Acme
It should return the last Version No of each Sales order.
Does that make sense? It is something probably easy... But, I've spent two days using multiples and multiples of different ways, that just aren't working: I'm about to dropkick my server cabinet...

tblOpenSiteDates
Site: int
OpenDate: smalldate
Comment: VarChar
tblCloseSiteDates
Site: int
CloseDate: smalldate

newLocationID: int
I am trying to get a view which would display a site with the open and close dates. Null is ok for a close date for those opens that are still open.. not every office has an open date and close date.. it is possible to have just a close date and not an open date (ie unsure of open date but I know its closing)
so the output would be

I have a requirment to take data from a large set of tables where thetotal number of these tables may change on a regular baisis andoutput into another table. All the tables willl have the samecolumns. Frequency is being debated but it maybe as much as once perhour.Example1) I need to choose all the following tablesselect * from dbo.sysobjects where name like '_CPY%.2) then I need the followingfor each of the tables found above, I need the outfrom from each ofthose tables to be inputted into another table. basically, I wouldwant the following output from each of the tables found in step 1select machineid,name from _cpy_offermanager_6783) In the end I would have something like dbo.ALLCPY with recordscombined from all other _CPY tablesRon Sorrell
View 2 Replies View RelatedTable structure: col1 IDENTITY (seed=1 increment=1) + few other columns (col2...col7) + one text column (col 8)
I have around 50,000,000 rows per day inserted in the table T1. At the end of the day 40,000,000 rows are deleted. I have to keep the records for 12 months and then archive it. Database is 24/7 web serving and there is no down time allowed. IDENTITY column will go out of range (overflow) after less than two years, unless the identity seed is reset to the start value (seed=1, increment=1).
At the end of 12th month data is archived in another table and only last month is kept in the table T1. So table T1 enters new year with data from last month of the previous year. There are few other tables that refer to this table by using there own field with values from T1.IDENTITY column (referential integrity is not enforced). Identity column in T1 is needed as a unique id for some search actions. Performance is an issue therefore bigint data type is used for this identity column rather than decimal.
Another problem I have is how to do table update on one column (1 mil rows to be updated out of 2 mil of rows) with the minimum impact on the users who are querying this table heavily. Not need to mention that it is web app 24/7 no down time.
Thank you in advance.

I am trying to export the data from a number of MSSQL 2000 tables to UTF8 csv files.
Using the bcp that came with MSSQL 2000 didn't work (UTF8 related), so I am now accessing the 2000 database from within MSSQL 2008 R2 Management Studio and use its Import and Export wizard that does make UTF8 exports possible.
But it fails. This is the error I got for one table.

View 3 Replies View RelatedHi,
I'm Arash Baseri a Sql Server2000 developer and mail you from Dubai (U.A.E). I have a problem in Sql Server locking table. My problem is not reasonable so the more I researched the more I understand it is not my problem .it is a bug in Sql Server2000.
Now I explain the situation:
I have two tables (Table A and Table B).Table A has a clustered index on col1 and col2, Table B has a clustered index on col1 and col2. I join these tables and update col3 in table A, like this
begin tran
insert [Table A]
select * from Arshiv_Master where Col1 between 26001 AND 26001
Update AI31 set Col3=Case
when 1=1 then 1
Else 0 End
From [Table A]AI5, [Table B]AI31
where AI5.Col1=AI31.Col1 And AI31.Col1 Between 26001 And 26001
/* intentionally I didn't rollback or commit transaction to hold locks on table*/
In another connection I execute this query and I face "Lock request timeout period exceeded" error message.
set lock_timeout 1
set transaction isolation level read uncommitted
Update AI31 set Col3=Case
when 1=1 then 0
Else 0 End
From [Table A] AI5, [Table B] AI31 where AI5.Col1=AI31.Col1 and AI31.Col1 between 45018 And 60000
Now the most interesting part is here .when I use a smaller data range for Col1 no error message is shown. A query like this
set lock_timeout 1
set transaction isolation level read uncommitted
Update AI31 set Col3=Case
when 1=1 then 0
Else 0 End
From [Table A] AI5, [Table B] AI31 where AI5.Col1=AI31.Col1 and AI31.Col1 between 45018 And 50000
As you see the difference between the last two queries is on WHERE clause especially on data rages of Col1.
As you know Sql Server 2000 has row level lock and when I acquire a lock on a record the other records are free. So what's wrong with Sql Server that assumes the others records are locked. I tested this situation in Sql Server 2005 and this problem was not seen so I think it's a bug in Sql Server 2000.Who can help me about this problem?

I am opening a simple command against a view which joins 2 tables, so that I can return a column which is defined as a tinyint in one of the tables. The SELECT looks like this:
SELECT TreatmentStatus FROM vwReferralWithAdmissionDischarge WHERE ClientNumber = 138238 AND CaseNumber = 1 AND ProviderNumber = 89
The TreatmentStatus column is a tinyint. When I execute that above SQL SELECT statement in SQL Server Management Studio (I am using SQL Server 2005) I get a value of 2. But when I execute the same SQL SELECT statement as a part of a SqlDataReader and SqlCommand, I get a return data type of integer and a value of 1.
