I have a table that has a PK index on a VARCHAR(10) field. I insert 'A'. Next I try to insert 'A '. The insert isn't allowed because of the index. How can I make it so that 'A ' is allowed to be inserted?
Thank you in advance.
EDIT: The first is just A. The second was A[space].

yeah, primary keys are a nuissance; they have a habit of wanting to be unique. Remove the old 'A' before you insert a new 'A'.

If you genuinely need to add a second 'A' (rather than just trying to find out what happens if you do), then the chances are that the design of your database is less than optimal.

yes, there is an issue with trailing spaces; here[^] is one discussion of that topic. I would avoid such situations by trimming all text before it goes into the database, otherwise you'll get trouble sooner or later, as you can hardly see the spaces at all and they may cause your selections to behave inconsistently.

Too slow Pattyn! 
I still think it's in the wrong place. Shouldn't it be a reply to the OPs' second post?

OK. You get away with it.............this time.

I had a PHB asked me once if I could make the spaces blink. That way they could be seen.

That makes perfect sense: show all special characters the way MS Word does ("show/hide P"), however don't do it permanently, give the user the option to blink them.

VARCHARs don't make good primary keys anyway.

hi
SELECT *

In the above query, I have more than 128 characters to search in like predicate, what should be in this case ?
and the error message is
The identifier that starts with is too long. Maximum length is 128.

Strange: I tried your query with SQL Server 2000 and that did not produce an error message.
By the way, Employees.FirstName is a nvarchar(10), hence the long search term is not very useful here anyway.
What do you actually want to do? Do you want to get a list of employees whose FirstName contains either 'abc' or 'def'? That would be WHERE FirstName Like N'%abc%' OR FirstName Like N'%def%' and so on.

FormView1.FindControl("TextBox2") as TextBox;
I need like it to select the value for DrowpDownList inside GridView
|
|
|
|
|
(GridView1.Rows[Index].findControl("DropDownList1") as DropDownList).SelecteedValue
|
|
|
|
|
I tried your code . but there is some error :
Compiler Error Message: CS0122: 'System.Data.Index' is inaccessible due to its protection level
|
|
|
|
|
Try this code in selectedIndexChanged event of dropdownlist
DropDownList ddl = (sender as DropDownList);
string val = ddl.SelectedValue;
|
|
|
|
|
try this
foreach(GridViewRow gr in Gridview1.Rows)
{
string str = ((DropDownList)gr.FindControl("DropDowmList1")).SelectedValue;
}
|
|

|

please see the following url
http://tareemnet.com/drop.JPG
User Name : adnet
Pass : 123
When Editting, the user can change the value using the dropdownlist, and then updating with that new value selected.
I'm beginner, please provide me a full code in c# for that issue.

I could execute the following sql in SMSS, but when adding it in a sqldatasource as an update statement, it gets an error.
In SSMS, and it works fine:
UPDATE S
SET S.DailyBudget = 12
FROM Account O INNER JOIN AdCampaign S
ON O.ID = S.AccountID
WHERE O.EmailAddress = 'abc@abc.com'
But In Sqdatasource, it gets error:
UPDATE S SET S.DailyBudget = 12 FROM Account O INNER JOIN AdCampaign S ON O.ID = S.AccountID WHERE (O.EmailAddress = @EmailAddress)
Error: Invalid Object Name 'S'.
Hint: S,O are borrowed names, and not actual table names.
