SQL Server :: Special Insert Constraint Rule For Two Columns?
Oct 19, 2010
I have a SQL Server 2000 table with 7 columns and would like to add a constraint that prevents a row being added with the same value for both Col2 and Col3.
So, for example, if Col2 = 205 and Col3 = 5, then the constraint should prevent inserting another row with the values for Col2 = 205 and Col3 = 5.
The following is an example of what I would like to prevent:
Col1 Col2 Col3 Col4 Col5 Col6
1 205 5 1 1 1
2 205 5 0 0 0

I want to create a constraint for 3 columns (A B and C) where if columns B or C are not null, then A cannot be null. And vice versa (i.e., if A is not null, then either B cannot be null, or C cannot be null).I am not very well versed in SQL and would like to know what is the best way to achieve this (e.,g Check constraint, stored procedure, function, trigger)? I'm leaning towards trigger but I'm not 100% sure if that's right nor of how to implement it.

How to programatically insert string with special characters into RTF? I have rtf template I load to string and then replace all $MY_VARIABLE$ with data. Data contains special chars like 'ąęść' and the problem is that in result file these characters are replaced with '?'. It's something wrong with encoding but what?
My code looks like:
StreamReader reader = new StreamReader("template.rtf");
StringBuilder form = new StringBuilder(reader.ReadToEnd());
// here I replace variables in rtf with data
Encoding srcEncoding = new UTF8Encoding();
Encoding dstEncoding = new ASCIIEncoding();
byte[] utf = srcEncoding.GetBytes(form.ToString());
byte[] asci = Encoding.Convert(Encoding.UTF8, Encoding.ASCII, utf);
return dstEncoding.GetString(asci);

I have a GridView that has several dynamic columns (I do not know how many at design time and it could be 0-12 columns, hence need for dynamic columns). I have the columns in the grid and data bound to them - works great. There are other standard, design-time TemplateField columns with TextBox controls in them. These are bound with values that the user can edit. The grid is posted back via a Submit button. My question is "Why does gv.Columns.Insert() cause all my TextBox data to be null on Postback, but gv.Columns.Add() works like a champ?"
protected void BuildColumns()
{
// The first column to begin to insert the columns in the GridView
int columnIndex = 5;
BoundField aoColumn = new BoundField();
aoColumn.HeaderText = "New Column 1";
gvMyGrid.Columns.Insert(columnIndex, aoColumn); // kills txtQuantity.Text on postback
gvMyGrid.Columns.Add(aoColumn); // works fine
columnIndex++;
foreach (MyEntity my in _myEntityCollection)
{
BoundField myColumn = new BoundField();
myColumn.HeaderText = String.Format("{0:d}", my.StartDate);
gvMyGrid.Columns.Insert(columnIndex, myColumn);
columnIndex++;
}
}
I then go on to assign values to these BoundFields in the _RowDataBound method and all of this works great. However, when I post back and try to reference some TextBox and they are all null. And yes, I have the BuildColumns() call wrapped in if (!IsPostBack) on Page_Load. Of course I would like to use .Insert() so that the columns can go in the proper location and not at the end of the Columns array.

I cannot get the value from the drop down list and I not sure what's wrong with the declaration and the code.
Dim selectedIntake As String = intakeDropDownList.SelectedItem.Text()
Dim selectedSupervisor As String = supervisorDropDownList.SelectedItem.Text()
.supervisor_ID = selectedSupervisor(0), _
.semester_No = selectedIntake(0) _
[Code]....
This is the error message I get :
The INSERT statement conflicted with the FOREIGN KEY constraint "FK_student_Details_lecturer_Details". The conflict occurred in database "SKTM-AAS", table "dbo.lecturer_Details", column 'supervisor_ID'. The statement has been terminated.

I have a table with three fields, User, City and Country, where exactly one of the fields must be non-NULL at all times. Can I use an SQL constraint for this or should I rethink what I'm doing?
The scenario is that my database should contain documents that can be attached to users, cities or countries. So a row in this table contains exactly one document for either a user, a city or a country. However, one should be able to search for all documents as well, regardless of what entity it has been "attached" to.
The reason I'm not using three different tables instead is that I want to avoid having to JOIN the three tables when searching for documents in all of the three places. I'm imagining that the kind of denormalization I'm attempting to use here will improve performance.

let say i have 2 table (PARENT and STUDENT table)
the structure for both table are
STUDENT
PARENT
student_id (PK) parent_id (PK)
student_parent (FK) parent_status (the value is either ACTIVE OR INACTIVE)
- parent_id is refer by STUDENT table as a foreign key
- now i want to inactive the status for parent
- i want my system pop out a message something like "The parent you want to inactive is refer by a student, inactive is not allow"
- is it any constraint in SQL Server 2005 to help me check whether parent it is refer by student table? The concept i want to use is something like delete constraint in SQL Server 2005 mean it is not allow to delete a person who is refer by a student in STUDENT table.

Response.RedirectPermanent(Url); can redirect permanently to a url.
However, during my SEO process, I decided to change my routhing rule.
For example,
I change "/tag/{tag}-quotes" routing rule to "quoes-about/{tag}", but I don't want to lose all the traffic to old routing url.
What is the best way to handle this permanent redirection?

I am having problems with the following update query that is part of an SQL Datasource. This query was automatically generated by VS2008 and I have formatted it so that it is easier to read.
UPDATE tblowner
SET altownerid = @AltOwnerID,
name = @Name,
address = @Address,
phyadd = @PhyAdd,
phone = @Phone,
fax = @Fax,
cellphone = @CellPhone,
email = @Email,
COMMENT = @Comment,
attention = @Attention,
contact = @Contact,
ownerdesc = @OwnerDesc,
taxid = @TaxID,
financialcontact = @FinancialContact,
fyenddate = @FYEndDate,
firstname = @FirstName,
lastname = @LastName,
stampinit = @StampInit,
stampdate = @StampDate,
zipid = @ZIPID,
[ZIP+4] = @N'@[ZIP+4]'
WHERE ( ownerid = @original_OwnerID )
Everything works but the [ZIP+4] field which does not update. I believe that VS2008 added the square brackets around the field name because of the plus character that it contains. If I change the ZIP+4 variable name to [ZIP+4] = @ZIP4 it still does not work. This brings up another question, I have never understood where these update queries are getting their data from.
