Good morning,
i have four tables
Student(iid , lname, address)
Teacher(tid, lname, salary, d_number)
Lesson_teach(tid,les_name)
Lesson_attend(iid,les_name)
Well, I'm trying to find the teachers who teach one lesson and more (e.g. only if sm teaches >= 2 lessons )
I do:
select teacher.lname
from teacher,lesson_teach
where teacher.tid = lesson_teach.tid
group by lesson_teach.tid
having count(*) >= 2)
Thanks,in advance!
Hi, I don't use SQL much but I need to know how to form the following query against a SQL table. I have a single table with two columns - CurrentPage and LastPage.
I need to write SQL to perform a number of iterations of a particular insert into another table, depending upon the count from CurrentPage to LastPage i've put the following Pseudocode together, but need help implementing this.
Declare counter
Set counter = currentpage
If counter > lastpage
Goto task exit loop
Else perform task - (insert string into table)
Increment counter and loop
I've been playing / reading up, but i'm getting nowhere fast -
DECLARE @Count int
DECLARE @Current string
DECLARE @Last string
SET @Current= dbSL.tblPaging_colCurrentPage
SET @Count= dbSL.tblPaging._colPagingCount
SET @Last= dbSL.tblPaging._colLastPage
WHILE @Count <= dbSL.tblPaging._colLastPage
BEGIN
PRINT 'Hello World'
SET @Count = @Count +1
END
Any help much appreciatted.
Thanks

I have a couple questions about replication (for both 2000 and 2005 servers):
1. which system tables/dmvs/system sprocs can I look at to determine which columns of a table are being replicated?
2. which system tables/dmvs/sprocs can I call to get metadata about publishers and subscribers?
Thanks!
0) We are migrating data from SQL Server 2000 OLTP design to SQL Server 2005 OLAP design.
1) We have an data flow task SSIS package.
2) We managed to send a mail with various variables & their values in subject or body of mail.
3) How do we send mail with details of Error/Warning using OnError/OnWarning events?
4) Can we have bad tables i.e where records which failed to migrate get inserted into. If yes, what are the steps to implement this.
5) Can we have a mix of in-built & custom logging. Is logging provider necessary to do logging. What logging provider to use?
6) Where are the errors that come during build, deploy, install and execute stored? Is there a log file(s) & what it their location?
7) Please post links if that is better.
Hi everyone,
I'm just a newbie with clustering.
We've got a 64-bit A-P cluster running with Sql25k 64-bit too.
Each node own two local network adapters. One of them (the one currently is Active) own three IP and the another one only one.
Why? From CLUADMIN I see as one of these three is set as Cluster IP Address in Active Resources. So I see the following configuration for the Active node:
Adapter 1: IP public for Active Directory
Adapter2: IP1 (reserved or ???????)
IP2 (used as SQL IP Address 1 in Active Resources)
IP3 (used as Cluster IP Address in Active Resources)
Passive node:
Adapter 1: IP public for Active Directory
Adapter2: IP (only have one ???)
Is this correct/necessary? Does anyone have similar configuration?
Thanks for your time,
I am interested in knowing the following things:
How to show total of all legend items in legend block itself as "Total".
How to show Total (say amount) in the center of donut chart.
How to customize the thickness of donut in donut chart and radius of inside and outside circle (the other thickness).
The lable markers (arrow) are not coming as a right angle arrows when i tried to use the donut and pie charts, the are coming as randomly angular lines which is hampering the beauty of the report.
Please reply as soon as possible. Thanks in advance.
Hello
I have a windows application that connects to a SQLExpress database hosted on a shared server. The client machines will run an interface software and interact with the info within SQL The SQL database isn't huge (50 megs) and all of the info is text. The interface application isn't too complex either, it was designed using VB.net05. I have a few setup questions:
1 - Is it best to use Windows or SQL authentiaction? Currently I am using Windows authentication and I have a user group setup on the DNS that is setup as a user for the SQL database. That has worked so far, but I've only had a few users logged in at one time so far. My plan was to add all DNS accounts that will use the software to the DNS user group, thus giving them access to the SQL database.
2 - I know this gets asked a TON, but I am interested in knowing how many users I should be able to support using the current setup. I have the one user acount setup for the DNS user group. The SQL table is not huge and it is all reading and writing text. The server is running Windows Server 03 and is a couple years old (not sure of exact specs).
Thanks for any help, I am still learning my way around SQL and it's great to have such a vast amount of support for the product.
Happy New Year!
Paul
Ok this has been bothering me for about a week now so I guess I'll throw the question to you guys...
I have a SP that does nothing but gives all product_ID's and gives me a count of each:
select product_id, count(product_id) from [Order's table] inner join [shipping's table] on ... where [order has not been shipped] group by product_id
With the where clause, I'm looking at a total of around 4000 orders that will be group by and counted out of a total of around 300000 entries in the table. Almost 30% of the time this SP will Timeout on the application calling it. I've looked at the application, did a lot of reading and made as many changes as I can to optimize the code on both the application and SP to make sure its as efficient as it can(I'm on version 10 now of this code and SP...). Is there any issues with doing group by and counts that I'm not aware of? Could this be an index issue...should I rebuild my indexs? Any suggestions on what to do next would be great.
Thanks ahead of time
Hi thanks for looking at my question
Using sqlServer management studio 2005
My Tables are something like this:
--Table 1 "Employee"
CREATE TABLE [MyCompany].[Employee](
[EmployeeGID] [int] IDENTITY(1,1) NOT NULL,
[BranchFID] [int] NOT NULL,
[FirstName] [varchar](50) NOT NULL,
[MiddleName] [varchar](50) NOT NULL,
[LastName] [varchar](50) NOT NULL,
CONSTRAINT [PK_Employee] PRIMARY KEY CLUSTERED
(
[EmployeeGID]
)
GO
ALTER TABLE [MyCompany].[Employee]
WITH CHECK ADD CONSTRAINT [FK_Employee_BranchFID]
FOREIGN KEY([BranchFID])
REFERENCES [myCompany].[Branch] ([BranchGID])
GO
ALTER TABLE [MyCompany].[Employee] CHECK CONSTRAINT [FK_Employee_BranchFID]
-- Table 2 "Branch"
CREATE TABLE [Mycompany].[Branch](
[BranchGID] [int] IDENTITY(1,1) NOT NULL,
[BranchName] [varchar](50) NOT NULL,
[City] [varchar](50) NOT NULL,
[ManagerFID] [int] NOT NULL,
CONSTRAINT [PK_Branch] PRIMARY KEY CLUSTERED
(
[BranchGID]
)
GO
ALTER TABLE [MyCompany].[Branch]
WITH CHECK ADD CONSTRAINT [FK_Branch_ManagerFID]
FOREIGN KEY([ManagerFID])
REFERENCES [MyCompany].[Employee] ([EmployeeGID])
GO
ALTER TABLE [MyCompany].[Branch]
CHECK CONSTRAINT [FK_Branch_ManagerFID]
--Foreign IDs = FID
--generated IDs = GID
Then I try a simple single row DELETE
DELETE FROM MyCompany.Employee
WHERE EmployeeGID= 39
Well this might look like a very basic error:
I get this Error after trying to delete something from Table €œEmployee€?
The DELETE statement conflicted with the
REFERENCE constraint "FK_Branch_ManagerFID".
The conflict occurred in database "MyDatabase",
table "myCompany.Branch", column 'ManagerFID'.
Yes what I€™ve been doing is to deactivate the foreign key constraint, in both tables when performing these kinds of operations, same thing if I try to delete a €œBranch€? entry, basically each entry in €œbranch€? and €œEmployee€? is child of each other which makes things more complicated.
My question is, is there a simple way to overcome this obstacle without having to deactivate the foreign key constraints every time or a good way to prevent this from happening in the first place? Is this when I have to use €œON DELETE CASCADE€? or something?
Thanks
1. Is it legal and OK to use a MSDN SQL copy on a production environment or is it strickly for test environments ??
2. If I own a legal copy of SQL 7 with 5 cals, can I legally use SQL MSDE and have more than 5 people access my SQL server or am I also limited to 5 users as my original ??
Sorry I am a newbie at this SQL thing.
Hi,
Is there a format function in MDX which will help me solve the following
scenario:
One of my measures is Net Sales and I have tried all different formats
in Analysis Services so that it shows without the decimal places i.e.
instead of showing the Net Sales for any selected combination of
Dimensions as 123,456.04, I want to show it as 123,456
When I browse the cube (in Analysis Services), I can meet my
requirement. However, in my front-end (Microsoft Data Analyzer), I am
still getting it as 123,456.04 (even when the same in Analysis services,
i.e. when I browse the cube, is being shown as 123,456).
I do not have much choice at the moment and am stuck with Microsoft Data
Analyzer and unfortunately have not been able to solve this :(
Can someone think of a solution/workaround/use of MDX which will help me
get the results being displayed without the decimal. Is there a format function that I can use in MDX and how to use it???
Many TIA
Hello,What is uniqueidentifier as a data type?Also what is the data type for setting unique STRINGS ((nchar,nvarchar), for example to be used for emails and user names in a userregistration system).SQL Server does not allow me set primary keys for columns where datatypes are not INT.Thanks in advance.
View 3 Replies View RelatedI've been working on a performance review web application (i.e., employee's annual reviews done via the web). In the process of creating the application I've been teaching myself .NET - maybe not the best way to do it but I've been learning a lot. However, I still feel like I'm not doing something right.On each Page_Load I'm doing database work with a data reader: Reading the data in, displaying it, letting the user add, edit, or delete it, etc. So every Page_Load code behind looks like this: string sql = "SELECT UserID, Passwd, RecID, Name FROM UserList";
SqlConnection myConn = new SqlConnection("Server=BART; Database=WSSD; User ID=sa; Password=wss1231");
SqlCommand cmd = new SqlCommand(sql, myConn);
SqlDataReader dr;
myConn.Open();
dr = cmd.ExecuteReader(); And so forth and so on. Now since I re-use this code again and again - I imagine it's a good idea to implement my connection code in a class that I can re-use easily. But I have no idea where to start on something like that. What can I say? I'm a newb. A push in the right direction would be great.

Hi,
I made a DTS which appends data coming infrom a view to an exisiting table.So far no problem and all goes well.
I am facing a problem due to the format of the date that is coming in (getting appended) and while going through BOL, came across the following topic:
mk:@MSITStore:C:Program%20FilesMicrosoft%20SQL%2 0Server80ToolsBookshowtosql.chm::/ht_dts_trns_97ou.htm
I tired the above tips but it appears that if I try to do this in my DTS (which appends data),the logic of the DTS will change. A single arrow also gets added whichI think represents a simple mapping/transformation rather than a append. To clarify my point, please note the attached image which represents that the data is being appended (due to the many sided arrows pointing to the source and destination - visible under the Transformations tab of my DTS).
Sincerely hoping that my post is clear, can someone help me find how to make changes in a DTS (which appends data) and ensuring that thelogic remains the same i.e. it should append data.
Many TIA

Hi,
I have a data including "year", "month" and "day" columns and I'm using these columns as parameter to create a report. I'm using the parameters successfully in my report. I import all possible year-month-day combinations but in my data there are some unmatched combinations. (For ex, for 2007 there's just last 3 months of the year, and some days are missing) To make the report more affective, I wanna make the parameters dynamic; when I choose 2007 in year-combobox I wanna see just the related months (not all 12) and the related days after I choose the month. Is it possible in reporting services?
HelloWhen I use a PreparedStatement (in jdbc) with the following query:SELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = ?ORDER BY group_nameIt takes a significantly longer time to run (the time it takes forexecuteQuery() to return ) than if I useSELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = 'M'ORDER BY group_nameAfter tracing the problem down, it appears that this is not preciselya java issue, but rather has to do with the underlying cost of runningparameterized queries.When I open up MS Enterprise Manager and type the same query in - italso takes far longer for the parameterized query to run when I usethe version of the query with bind (?) parameters.This only happens when the table in question is large - I am seeingthis behaviour for a table with > 1,000,000 records. It doesn't makesense to me why a parameterized query would run SLOWER than acompletely ad-hoc query when it is supposed to be more efficient.Furthermore, if one were to say that the reason for this behaviour isthat the query is first getting compliled and then the parameters aregetting sent over - thus resulting in a longer percieved executiontime - I would respond that if this were the case then A) it shouldn'tbe any different if it were run against a large or small table B) thisperformance hit should only be experienced the first time that thequery is run C) the performance hit should only be 2x the time for thenon-parameterized query takes to run - the difference in response timeis more like 4-10 times the time it takes for the non parameterizedversion to run!!!Is this a sql-server specific problem or something that would pertainto other databases as well? I there something about the coorect use ofbind parameters that I overall don't understand?If I can provide some hints in Java then this would be great..otherwise, do I need to turn/off certain settings on the databaseitself?If nothing else works, I will have to either find or write a wrapperaround the Statement object that acts like a prepared statement but inreality sends regular Statement objects to the JDBC driver. I wouldthen put some inteligence in the database layer for deciding whetherto use this special -hack- object or a regular prepared statementdepending on the expected overhead. (Obviously this logic would onlybe written in once place.. etc.. IoC.. ) HOWEVER, I would desperatelywant to avoid doing this.Please help :)

Locally I have a table named 'countrydetails' in sql server which is created by dbo. I create asp.net page trying to show the details of the country. I write a query in vb.net page and build the project and try to run it, its giving me results.
The same vb.net project is uploaded and put online and when I try to see the details of the country online inspite of having records i m getting no results. In this case the table which was created is having username other than dbo.
I want my query written in vb.net page to run irrespective of the different users who have the database table. The page should run for both dbo and other users also. How do I achieve this? Please advise.
