See the following site[^] for details on how to create different connection strings. You should use something like this:
Data Source=myServerAddress; Initial Catalog=myDataBase; User Id=myUsername; Password=myPassword;

Thanks for the reply, Paul.
I already know the connection string. What I am inquiring for is how to make my SQL Server run on SQL Authentication with username and password.
Thanks.

Use the CREATE LOGIN[^] and CREATE USER[^] statements to create a new SQL login and grant it access to a database.
For example:
USE master
GO
-- Create database login
CREATE LOGIN Paul WITH PASSWORD='p@ssw0rd1'
USE myDB
GO
-- Assign login rights to access myDB
CREATE USER Paul FOR LOGIN Paul
You can do the same thing through the Management Studio UI.
Hope this helps.

Hi all ,
I created a Login in sql server 2005 and set its permissions and created a user mapped to it , I have a .net app that connects to this database , How should I deploy this database with my .net app that is going to run server-based ? When using Windows Authentication Mode , to which Login should I set permissions? Should I write a script for setting these permissions?
Thanks

Depends on the version of windows, IIS you use.
For XP+IIS 5.0 you should add a windows login for ASPNET account
for Win2003+IIS 6.0 you should use NETWORK SERVICE user.
You can generate a SQL Script of your database and run it with the installation package to create DB and users.

Hi All,
I havnt got any response from CodeProject, but I have solved the issue myself. I tried creating Clustered And Non-Clustered Index into a table (Important table that appears in most transactions).
Also i have created some Maintenance paln that executes DBCC commands automatically.

hi,
i have three layers.
1)form.cs
2)datalayer
3)database(forget about this since it is used to open and close the connections form the ms access)
i have two text and a single combobox.
basic idea is i want a query that will search even if any one of these fields are selected.
also do the same if two are selected.
also do the same if one is selected.
the code to search will have to be on my btn click for serach event(ie is in layer form1.cs).
it will have to call my query that will be in a fn: that is in datalayer ( public DataTable refinesearch(string searchstr1, string s2, string s3)
so i think i need to use "like" condition.
something like
"select * from Employee(name of the table) where name like "string" where empid like "s2" etc........
this is my problem .i do not know the query.
thanking you and expecting your reply....

if datatype of column EmpId is integer then you can not use like statement just
>,<,=,<> but if column EmpId is varchar then you can use like statement
--if empid is integer
select * from Employee where name like '%string%' and empid=1
--if empid is varchar
select * from Employee where name like '%string%' and empid like '%1%'

Guys im having a problem with this statement..
ALTER TABLE tblSample
ADD SampleField nvarchar (30) NOT NULL
CONSTRAINT SampleField PRIMARY KEY
im just trying to set my newly added column and at the same time setting it as a primary key.. but it wont work..
Is there any other way?
or can it set an existing non primary column to a primary one.. if it can then how.. thanks..

Please supply error messages etc as "won't work" is an interpretation and not an observation of what actually happened.
Have you checked that SampleField contains unique values?
Primary keys can only be assigned to columns with unique values.
You always pass failure on the way to success.

Several problems:
- You haven't specified a default value for SampleField and have disallowed NULLs so the database doesn't know what value to give that field for existing rows in the table (it would normally use NULL but you've disallowed it);
- Even when you do add a default value or allow NULLs primary keys must be built on unique values, and every row in the table will then have the same value in that column;
- The SQL syntax for ALTER TABLE doesn't allow you to do both at the same time anyway;
- The SQL syntax for adding a primary key is:
ALTER TABLE tblSample
ADD CONSTRAINT PK_tblSample PRIMARY KEY
( SampleField ) PK_tblSample is the name I've given to the constraint, which you need if you later want to drop it. If using CREATE TABLE, you can set the primary key to a single column simply by stating PRIMARY KEY after the column definition, but the name is generated by SQL Server making it harder to use later.
You can define a primary key on a table that doesn't already have one by using the syntax above. You can create compound keys - keys consisting of multiple column values - by including all the key columns between the parentheses.

What I suggest is that you create a dataview based on your datatable.
Bind this dataview to your datagrid.
You can then filter, sort etc on the dataview without changing the contents or base data in your datatable.
Below is an example in VB .NET on how I have filtered and sorted using a dataview:
<br />
dvFileList = New DataView(tblFileList)<br />
dvFileList.Sort = "bytes desc"<br />
filter = "filetype = '" & DataGrid1.Item(DataGrid1.CurrentCell) & "'"<br />
dvFileList.RowFilter = filter<br />
DataGrid1.DataSource = dvFileList<br />
You always pass failure on the way to success.

The first 3 columns of my report are dynamic, depending entirely on parameters passed to the stored procedure. The result set from the stored procedure is used as the dataset in my Reporting Services report. Sometimes there are fields that are not returned in the result set and I wanted to display blanks if they weren't there. I tried all the tricks using iif(isNothing(Fields!field1.Value, "",Fields!field1.Value) and using Fields(Parameters!parm1.value).Value in my argument list. Neither of these worked.
I created 3 textboxes in my report (table) and placed the three different values in them, i.e., Fields!field1.Value, Fields!field2.Value, and Fields!field3.Value. In certain cases, one or two of these fields would not be returned in the result set. I made them hidden. Then in my other textbox, where I wanted to display the value, I added as the expression, Code.DetermineFieldValue(Parameters!parm1.value, ReportItems!txtTextBox1.Value, ReportItems!txtTextBox2.Value, ReportItems!txtTextBox3.Value)
I did this for each of the 3 textboxes, just replacing parm1 with parm2 or parm3.
In the embedded code, the function was defined as:
public function DetermineField(value1 as object, value2 as object, value3 as object, value4 as object) as object
I just refered to my fields as value1 through value4 and it worked. I have been trying this for about a week and couldn't get anything to work. Apparently, it will accept the textbox not having a value, but cannot handle the dataset field directly if it is not returned. It never got to the code. Hope this helps someone.

Your post is difficult to read. To make it more understandable, you should use the <code> and <pre> tags to format your code.
You can't bind a report control to a field in your data source and then not return the field. I had the same issue a couple of years ago when developing reports that allowed the user to pick up to 3 fields to group the data on. If less than 3 grouping fields were selected, some of the grouping columns needed to be hidden. I got round this problem by writing my stored procedures to pad out the resultset with extra 'dummy' fields if less than 3 grouping fields were selected. This way, the resultset would always have the same 'shape' and my data binding expressions would always work. In the report, I would then hide the grouping columns that were not required.
