I get this message when running an application from a remote computer with standard connection.

SELECT permission denied on object 'custGroups', database 'ValkyriaDB', schema 'dbo'

I have SQL 2005 express database and MS SQL server managament studio express.
I done this so far:

In the security - logins - 'USER' - properties i have mapped my username to the correct db (default db) and in user mappings for that db i have granted all database roles to my username. The default scheme is dbo.

For the valkyriaDB schemes - dbo i have granted (Grant and With Grant) all permissions.

I simply dont understand why i get this error message... Must be something i dont understand.

Please advice

PS. It is much easier with old MSDN, or any opensource DB, dont understand why it has to be so hard with MS.

ITs not hard with MS it just enforces strong security.

Check you can access the object through a query using the 'USER' and debug from there. You might want to specifiy the db in your connection string as well as speficing the instance name mymachine\SQLEXPRESS

Look where you want to go not where you don't want to crash.

Thx, it helped, but now i got a new problem. Now it suddenly says:

System.Data.SqlClient.SqlException: An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)

But still i can do connection.Open() from remote, i just can execute any statements. Where can i check if the server is set to receive remote connections?

BTW, my connection String:
="Server=MACHINENAME\SQLEXPRESS;Database=ValkyriaDB;UserID=XXXX;Password=XXX;Trusted_Connection=False;"

Thx for previous anserw, im new to SQL2005 or any MS database...

You are not using integrated windows security. Make sure that the SQL LogIn is a user in the db_datareader role in the database and you should be good to go.

you can use order by to select on a defined order of a column

<br />
select Top 10 * from table<br />
order by created_date <br />

i am trying to write a script. i need to copy the contents of my clipboard into a text file. then i need to save the text file as a htm file extention with a different name then i need to close both of the files. basically what i am doing is saving web page code in a filemaker pro data base. and i want to take the contents of a field that contains my code. and save itr as a htm file. is there any scripting language that will allow me to do this.

Sure, shouldn't be terible difficult with a scripting language such as VBS (Visual basic Scripting), the MSDN has a bunch of examples.

I want to add a new row to my datatable,then set this row is Currentrow
in BindingContext, so i change the BindingContext.Position for moving to the new row.

I have two forms,I can change the "BindingContext[mydatatable].Position" in one form ,but this cannot be implemented in another form .Who can tell me why?The code is:
DataRow dr = GdtKeyPoint.NewRow();
GdtKeyPoint.Rows.Add(dr);
this.BindingContext[GdtKeyPoint].Position = GdtKeyPoint.Rows.Count;
//or this.BindingContext[GdtKeyPoint].Position = GdtKeyPoint.Rows.Count-1;
//also can`t be implement. no error was raising!!

Are you using .Net 2.0? If yes, then try using BindingSource instead.
If not, then try working with the CurrencyManager instead of the BindingContext.
[edit]You can get the CurrencyManager from the BindingContext, and that's supposed to be the object that you edit instead./edit]

retrieving the value in a column using a dataTable

Glen Harvy31-Jul-06 16:00

Hi,
using C#;
using VS2005;

I have a dataset that contains several datatables. What I wish to do is search each row in one of the tables and read/copy the value of a column into a variable. I will then manipulate the variable as needed. Specifically, the dataTable is "MembershipDetails" and the column is "MembershipNumber". The dataset is called "myclubDataSet".

The purpose of all this is to determine the next sequential membership number.

If someone could be so good enough to write the code for me I would very much appreciate it because I can't find a simple straightforward example anywhere on the net to learn from.

I know how to do a sql command to do this but I don't want to do it on the database. I wish to achieve it using the dataset.

Thanks in advance.

This seems a very hard way to do a simple task.

Run following sql code to get a last membership number

<br />
select top 1 MembershipNumber<br />
from myclubDataSet<br />
ORDER BY MembershipNumber DESC<br />

This will no however stop two user from trying to create the same membership number after getting the same last number from the database.

What you really want to do is return the membership number after creation

Make 'MembershipNumber' and identity column on your database and use similar codeas below,

<br />
insert membername, memberdetails<br />
VALUES ('Joe Bloggs', '15 Anyplace Road')<br />
<br />
SELECT @@Indentity<br />
<br />

The select @@Indentity will get the newly created memebership number. Try it in SQL before you try and code it.

Look where you want to go not where you don't want to crash.

That seems to be the way I do everything nowadays Mad | :mad:

.

I have some database/SQL experience with designing websites that use databases and understand your suggestions pretty well BUT I need to achieve my aim without going back to the database. I really want to learn how to retrieve the value of a column in each row or specific row.

With a bit of help from elsewhere I've got as far as:-

DataTable table = myclubDataSet.Tables["MemberDetails"];
DataRow[] foundRows;
foundRows = table.Select("MembershipNumber > 1 ");

for (int i = 0; i < foundRows.Length; i++)
{
int num = System.Convert.ToInt32(foundRows["MembershipNumber"]);
MessageBox.Show("Membership number is: " + num);
}

But this leads to a build error message:

Error Cannot implicitly convert type 'string' to 'int'

with the culprit being MembershipNumber even though that column is defined as an Int32 in the datatable.

I hope you can see what I'm trying to learn to do and can just help me over this hurdle Smile | :)

Thanks,

After much, much searching and a bit of a hint here, a bit of false leading there and a lot of building I ended up achieving what I wanted as follows:

private void defaults()
{
this.memberDetailsTableAdapter.Fill(this.myclubDataSet.MemberDetails);

int totalRows = myclubDataSet.MemberDetails.Rows.Count;
short maxMemNum = 0;
short nextMemNum = 0;
for (int i = 0; i < totalRows; i++)
{
short MemNum = (short)myclubDataSet.Tables["MemberDetails"].Rows[i]["MembershipNumber"];
if (MemNum >= maxMemNum)
{
maxMemNum = MemNum;
nextMemNum = ++maxMemNum;
MemNum = nextMemNum;
}
}
this.editMembershipNumber.Text = nextMemNum.ToString();
}

Just guessing that the space character between Central and Coast is causing the problem. Try

RESTORE DATABASE 'Central Coast' from disk = 'C:\centralcoast_db_200602020948.BAK'

or is the database called 'CentralCoast'?

How do I Insert a copy of a record when I want to change ONLY one field..

INSERT INTO tb
SELECT field1, field2, field3, field4, field5
FROM tb AS tb_1
WHERE (field1 = @Value)

None of the selected items are the primary key, and this insert works fine for a perfect clone, but I need to be able to modify field1 with a textbox the user can type in.

I know there is VALUE keyword.. but I can't seem to get it to work for just field1.
