Newbie Question: Referencing A Database Field...
Sep 26, 2006
Hi all, I am still in the process of learning ASP.NET.
The simple goal I am trying to accomplish is to set a string equal to a field in my SQL Database using ASP.NET.
I am just not sure what the correct syntax is to do so. It may be work noting that I am programming in VB.NET.
I have my SQL Data Source setup correctly and inserted into my form with an ID of "PDCalculations".
The field that I want to reference is "Percentage" which is an integer field.
The reason I want to put the amount into a string is so I can use it in some calculations that are happening on my form.
Thanks in advance.

I would have a question, if it is possible to reference a calculated field in T-SQL query. The following expression does not work in SQLExpress 2005
SELECT Qty, UnitPrice, Tax, Qty*UnitPrice as Expr1, Expr1*(1.0 + Tax) AS Expr2
This problem has occurred after upsizing to SQLExpress from Access XP/Jet Engine. Since Access does not have any issue with the expression above, the SQLExpress does not even accept it.
The only way how to avoid the issue in the SQLExpress seems probably to be
- Duplicate some calculations (i.e. expand every expression with duplicating some mathematic operations with some performance loss)
- Utilize computed columns if possible (no idea on performance impact here)
Am I right or is there any other way how to reference a calculated field?
Any suggestion is greatly welcomed! Thanks in advance.

I ran into an interesting situation. I'm working on contract and was looking at creating an ERD for an existing database when I ran into a problem. I found FK's that are referencing columns that do not have a unique constraint or a unique index.Â
I don't know the history of the database but was there a time in SQL Server history where this would have been possible? I scripted out the tables and created it in a test database. When I run the script to create the FK I get the following message.Â
I double checked the original tables and this FK does exist in table1 and there is no unique anything in the referenced table, table2. Currently the database is running on SQL Server 2008 Ent.
ALTER TABLE [dbo].[table1] WITH CHECK ADD CONSTRAINT [FK_table1] FOREIGN KEY([Col1])
REFERENCES [dbo].[table2] ([col2])
There are no primary or candidate keys in the referenced table 'dbo.table2' that match the referencing column list in the foreign key 'FK_table1'.

I am using SSRS 2014 SP1 x64 and VS2013 Update 5.
I have the following expressions to attempt to calculate ageing on a statement report.
=SUM(IIF(DateDiff("d", (Fields!OrderDate.Value, "Invoice"), Now())<=0, (Fields!LineAmount.Value, "Invoice"), 0))
=SUM(IIF(DateDiff("d", (Fields!OrderDate.Value, "Invoice"), now())>=1 and DateDiff("d", (Fields!OrderDate.Value, "Invoice"),Now())<=30, (Fields!LineAmount.Value, "Invoice"), 0))
=SUM(IIF(DateDiff("d", (Fields!OrderDate.Value, "Invoice"), now())>=31 and DateDiff("d", (Fields!OrderDate.Value, "Invoice"), Now())<=60, (Fields!LineAmount.Value, "Invoice"), 0))
=SUM(IIF(DateDiff("d", (Fields!OrderDate.Value, "Invoice"), now())>=61 and DateDiff("d", (Fields!OrderDate.Value, "Invoice"), Now())<=90, (Fields!LineAmount.Value, "Invoice"), 0))
=SUM(IIF(DateDiff("d", (Fields!OrderDate.Value, "Invoice"), now())>=91, (Fields!LineAmount.Value, "Invoice"), 0))
Now when I try to add First to the field selector I get an error stating ... uses a First, Last or Previous aggregate in an outer aggregate.
How exactly do I reference this field from the Invoice dataset (there are at least two datasets)?

For example, the table below, has a foreign key (ManagerId) that points to EmployeeId (primary key) of the same table.
-------Employees table--------
EmployeeID . . . . . . . . . . int
Name . . . . . . . . . . . nvarchar(50)
ManagerID . . . . . . . . . . . int
If someone gave you an ID of a manager, and asked you to get him all employee names who directly or indirectly report to this manager.
How can that be achieved?

Hi there
I sorry if I have placed this query in the wrong place.

The database is definitly in the folder that the error message relates to.
What I'm finding confusing is that the connection string seems to be finding "aranga"s database.
Is it something daft?
Many thanks.

Hi All,
I am designing database where few of the master tables will reside in different database or in case different server. Scenario is
Server "A" with Database "A" may host the "Accounts" table.
Server "B" with Database "B" may host the "Product" table.
I am designing database "Project" which will hosted in Server "A".
My application requires this master tables [readonly access] as data inserted in my application refers this tables. Also there are reports to be generated which refer this tables.
How do i design my database and sql queries?
I am thinking of approach of having equivalent tables created in my database and writing service which keep tables in my database in sync. This will ensure good perfomance during transaction and reports as they will need to refer this table locally as opposed to different database or different server.
Any thoughts on above approach?? or any better/standard way for such scenarios ?
Thanks in Advance. Your inputs will be of great help.

Hi all,
I wonder if there is anybody that can help with this one.
As you know, you can pass variables into a stored procedure and then use these variables for table names, columns etc.
Now, you also know that you can access another database on the same server just by typing the name of it into your query.
The hard part:
Instead of hardcoding the database name into the stored procedure i want to use a variable and then pass this to reference the database name, in the same way you would reference anything else with a variable. I need to do this as i have to search for various results across multiple databases.
We currently use SQL server 2000 standard, though are looking into SQL 2005 - especially is this problem is easy to resolve in the latter.
Look forward to your help
Regards
Darren

Hi there,
I'm a newbie. I've installed a replication between 2 NT4 servers, with SQL 6.5. My logreader tasks has crashed "Can't allocate space for objects 'syslogs' in database 'distribution' etc...". With a DBCC SQLPERF(LOGSPACE) I can see that the log is 100% full, but I can't dump it : when I use DUMP TRAN DISTRIBUTION WITH NO_LOG, my distribution log is still 100% full. So how can I do to dump it and what can I do to prevent it from filling up ? Do I need to dump it like I do for my database but how could it work if a DUMP TRAN doesn't work ?
Thanks in advance.
Sorry for the English, it's not my native language.

Hello everyone, I am new to mssql so please excuse all my silly questions.
I can create databases and tables. This is fairly easy, now I am having trouble with inputting data into the database using the data entry browser (or whatever it is called to enter data directly into a table).
I usually get an error when trying to submit the entry, firstly I have a "id" field which I think I have set to auto increase (Identity is ticked, seed and increment is set to 1).
when I go to add data all fields have "Null" in them and from what I understand it allows the fields to be empty, except the primary key which is the id field in this case and I expect that to be filled in automatically like with mysql but isn’t.
Can some kind person instruct or direct me somewhere on how to enter data into a table without it failing.
Thanks in advanced for any information provided.

Hello, Im new with databases.
I know that opening a connection to a DB is expensive. Usually I write a method that opens a connection to the DB then I execute a query and then close the connection. Pretty standard.
OK, so how do I handle opening connections to the database when I need to run multiple queries. For example, i have a webpage that need to query the database to see if the user has moderator privledges, then depending on that query I have to query the DB again for moderator specific information or non-modertaor information.
So in this case how do i handle opening connections to the DB. Is it ok to generally have to open a connection to a DB multiple times on a page load?
The obvious solution is to keep the connection open. That is, open a connection, query the Db, keep the connection open, do the conditional statment ( if is_Moderator) then query the DB again for the info that I need, and then close the connection. But, from all the books that Ive been reading this is not a good practice because business logic should not been in the dataAccess layer.
Any help would be much appreciated.

It was suggested to me to try and post this here in the sql express forum.
I am trying to query a specific field from my sse database based on two different variables. And use this information to fill a textbox with an integer.
The first variable is a combobox that is filled with data in one of the other tables in the sse database. This table has a PKcolumn that is an integer and the identity of the column. The only other column is a nvarchar(30) string (which is the actual data in the combobox)
The second variable is a numeric up down that isn't actualy using info from the database but will be a reference. It has a max value written in to the code:
if NumericUpDown1.Value > 20 Then
MessageBox.Show("This form only supports characters up to level 20")
NumericUpDown1.Value = 20
The texbox value will be found in a table that has several columns, the first column is an identity column (also the PK) then it has a column that holds an integer value (the filter criteria for the numeric up down) the next column has the value that will fill the text box, then several other columns that are irrelevant for this, and then the final column is a foreign key that is linked to the primary key of information found in the table that feeds the combo box.
I will post a picture of the database diagram to show all of this information for a better understanding of this post.
I am not looking for someone to write the code for me, but I am totally stumped as to what I need to do, If someone can help me out with this I would greatly appreciate it, thanks in advanced.

Hi,
I am very new to SQL Server and am just starting to look into replication as a possible solution to a problem I have. I have a local database which will be running on either MSDE or SQL Express 2005. I have a database on a webserver running SQL Server 2005 Standard which I wish to keep as an exact copy of the MSDE/Express one. If data is changed in the local db then I want the webserver db to be updated with this data, preferably as the change occurs, but it could be on an hourly schedule if required.
If data in the webserver db is altered then I do not wish for it to update the local db, but I would like it to be assumed that the change is erroneous and reset the item to whatever exists in the local db. In other words, should a table be erroneously dropped or something from the webserver db then the table would be recreated when it syncs with the local db (rather than propogating the change back to the local db and thus losing local data).
Basically I want the web db to be an exact mirror of the local db as often as possible. Given that the webserver is running SQL Server 2005 Standard and the local machine will be running either MSDE or SQL EXPRESS, is this achievable and what would be the best way of achieving it? Should I use merge replication or database mirroring? I have succeeded in getting 1-directional merge replication working by setting the webserver up as a publisher and distributor and setting up a push merge subscription on the local machine with an ExchangeType of 1. However, this won't correct the data in the web db if it is compromised until it is altered locally.
It crossed my mind that I could write a small application to utilise tablediff to compare each table in the DBs and get it to correct the web db if required on a regular basis. Would this be a silly approach?
I would appreciate expert advice!

Hi peoples...
I am a total newbie when it comes to SQL databases.
I currently work for a company developing software. We use a VB Development environment and connect to Dbase III database files using DAO... ewwwww...
We are looking to upgrade our development environment to VB.net and our database to either MSSQL or mySQL...
My question is - most of our users are on standalone machines. Our software is NOT internet based, nor do we want it that way at the moment.
Is there a way to connect to a MSSQL database (ie the .mdf file) without having a server running? Or are we better advised to stick to an MS Access database if this is the case....
Basically the reasoning behind upgrading is better speed and record locking. Any advice would be greatly appreciated.
I am sorry to sound so dumb...
Cheers,
Kev

Hello,
pls. let me know where I could post if this is the wrong place.
I have a Firebird 1.5 application. I created a linked server from my SQL
Server 2000 to the firebird database. In SQL Server Query Analyzer I get errors from various ODBC drivers with "normal" queryies like
SELECT LVNR FROM LINKEDSRV...LVVERW
Pls. note, this all works perfectly in MS Access databases with ODBC-Links to Firebird!
From a programmer of a commercial ODBC driver I heard that this problem may be caused internally by SQL Server, there may be no solution possible in the ODBC driver. One workaround would be to use the OPENQUERY-Syntax like
SELECT * FROM OPENQUERY(LINKEDSRV, 'select LVNR from LVVERW ')
Are there any other solutions? Are there any known issues with firebird odbc-drivers and sql server? Are
there any known good drivers for the use with sql-server? What is the purpose of OPENQUERY - workaround ODBC problems? Are there any settings in SQL Server 2000 (2005 Express) that could help? Are there any settings in ODBC DSN that would help?
regards

idea how I actually reference the fields via the SQLDataSource in a

The Background:
From page 1 a search is created and this value is converted to a querystring and given the name "id=" and passed to page 2. Page 2 then does a lookup in the sql 2000 db useing this querystring.
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ListingDBConnectionString %>"
SelectCommand="SELECT [ID], [CompName], [Package] FROM [CDetails] WHERE ([ID] = @ID)">
<SelectParameters>
<asp:QueryStringParameter Name="ID" QueryStringField="id" Type="Int32" />
</SelectParameters>
</asp:SqlDataSource>
The Problem:
What I then need to do is an IF THEN ELSE statement.
IF [Package in SQL1] = 4 Then
Package 4
IF [Package in SQL1] = 3 Then
Package 3
Only how do I reference the sql value in the if statement.
I have tried
<%IF Eval("Package") = 4 Then %> and with Bind - No good

Hi,
I'm using MS SQL 2005 Express.
CREATE TABLE Folder (
iD int NOT NULL IDENTITY (1, 1) PRIMARY KEY,
folderName varchar(50) NOT NULL,
parentFolderID int NULL
FOREIGN KEY REFERENCES Folder (iD)
)
GO
if I add an ON DELETE CASCADE to the foreign key, then i get an error... which is annoying. If a folder is deleted, then all its sub-folders should also be automatically deleted.
The error is: 'Introducing FOREIGN KEY constraint 'FK__Folder__parentFo__7D78A4E7' on table 'Folder' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints.'
Anyone got any advice?

I'm setting up a trigger that will fire off an email explaining that this entry has been updated, however I need a reference to the updated row so I only send that bit of information off.
Heres my code thus far:

BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from

SET NOCOUNT ON;

I thought the select From updated would work but it doesn't I need a reference for that line, select * FROM _____.

Hi
This is probably a noob question. In reference to my previous post about OLE DB and variables, I need to copy the whole result set to a table. i tried
Code Block
exec('insert into '+@tableName+' ('+@ColumnNames+') '+@curTableResult)
where @tableName is the table name, @ColumnNames are the column names and @curTableResult is the Result set produced by the Execute SQL statement before. Obviously didnt work.
How do I copy the Result set to a table?
Thanks

Hi there everyone,
A quick question. How do I reference variables (system and user) in SSIS by name instead of by just using a "?". The reason why I'm asking is because I'm trying to log what happens in a package to SQL, and if I cannot reference a variable by name it tries to insert variable values into incorrect fields?
An example of the code I'm trying to use can be found below:
Code Block
UPDATE dbo.History_Control_Table
SET
End_Date = GetDate()
, Result = 'Success'
, Status = NULL
, No_Of_Records_Processed = ? --This is where I want to tell it which variable to use
, Package_Name = ?
, No_Of_Records_Rejected = ?
--etc etc etc
WHERE
Package_Name = ?
AND Task_Name = 'Deals_Fact_Stg'
AND Status = 'Running'
Thanks in advance.
Chow.

This book 'MS SQL Server 2000 Bible' says the following:
'The foreign key can reference primary keys, unique constraints, or unique indexes of any table'
I've never heard of this before, I thought that the FK always established referential integrity by referencing the PK in the parent table. Does anyone have a further explanation of this?
thx,

Anyone know a way to pull specific fields from an excel spreadsheet.
I'm using SQL7 DTS to pull data into a SQL table. I can pull the entire
sheet but I just want certain fields.
thanks, archie

I would like a stored proc to be fed the table name as a paramater.
I tried below
create procedure testit as
set nocount on
declare @tblnm varchar(50)
select * from @tblnm
but it get Server: Msg 170, Level 15, State 1, Procedure testit, Line 5
Line 5: Incorrect syntax near '@tblnm'.
Any idea
