You want to set SQL Server Password using C# ? Or You want to open a database which is already password protected ?
If you want to open the database which has password, then you need to mention it in ConnectionString.

I think you are asking how to open a .MDF without having SQL Server, that is open the mdf directly from C#.
You can't, sql server requires a SERVER. I'm not sure if SQL Express will allow you to open the mdf directly.
Access will allow you to do this but you need the Jet engine installed.

SQL Express requires the DB Engine also.

Hello everyone,
I have simple query as:
SELECT so.title,max(so.nu_view)
FROM song as so,singer as si
GROUP BY so.title,so.nu_view
certainly, it will show the result, but to get achievement it needs a performing process, how to view this activity
Example: how to see combination between song and singer, how to see "group by" activity ...
does SQL server 2005 support this fuction ?
help me

Generally speaking your queries are executed (processed) in the following order:
1. FROM
2. ON
3. OUTER
4. WHERE
5. GROUP BY
6. CUBE | ROLLUP
7. HAVING
8. SELECT
9. DISTINCT
10 ORDER BY
11. TOP

I believe you're looking for something like the following:
USE AdventureWorks
GO
SELECT VendorID, [164] AS Emp1, [198] AS Emp2, [223] AS Emp3, [231] AS Emp4, [233] AS Emp5
FROM
(SELECT PurchaseOrderID, EmployeeID, VendorID
FROM Purchasing.PurchaseOrderHeader) AS p
PIVOT
(
COUNT (PurchaseOrderID)
FOR EmployeeID IN
( [164], [198], [223], [231], [233] )
) AS pvt
ORDER BY VendorID;

I have set the EMP_ID column in my database as the Primary Key. I mean this is the primary key column. And when I try to insert values in my database table from the form in then it gives me an error as:
"Cannot insert explicit value for identity column in table 'Employees' when IDENTITY_INSERT is set to OFF."
So, how is the IDENTITY_INSERT set to on. Where it is actually located so that I can modify it and start to insert values into my table.
Moreover, when I remove the primary key from this column(EMP_ID) and uncheck the Allow Nulls checkbox then also my same problem persists.
Kindly help me out. I am currently using SQL Server 2005.

it depends on what you want to do. if you want to enable insertion on identity column
SET IDENTITY_INSERT [ database_name . [ schema_name ] . ] table { ON | OFF } otherwise remove identity from the emp_id column and insert the value from field
|
|
|
|
|
sorry typo error i mean form not field
|
|
|
|

I think you are trying to insert a value into a identity column. If you are inserting the value into intentionally then you have to set Identity_insert tablename on/off. else ignore this column while inserting, sql server automatically inserts records into this field.
|
|
|
|
|
If you have access to the Management Studio of SQL Server, try and check the property for the column of your table in design mode, check the Identity Specification property...

There is a table called QCR100 containing the following information
ITEM_CODE ITEM_DESCRIPTION DCODE AMOUNT
111200 investments 24000003 1630000000.0000
111200 investments 126000005 1630000000.0000
111600 Other Assets 133000009 1700000000.0000
111600 Other Assets 150000002 1730000000.0000
111701 Leasehold 190010130 1740000000.0000
111705 Furniture 190010036 1750000000.0000
111706 Computer Software 190010141 46995799.1800
Then I created a view with this command statement:
SELECT CASE WHEN LEFT(e.dcode, 1) = '1' THEN isnull(SUM(a.Dr_bal_lcy - a.CR_BAL_LCY), 0) WHEN LEFT(e.dcode, 1)
= '2' THEN isnull(SUM(a.CR_BAL_LCY - a.Dr_bal_lcy), 0) ELSE 0 END AS amount, e.ITEM_DESCRIPTION, e.ITEM_CODE
FROM dbo.GLTEMP_CONS AS a RIGHT OUTER JOIN
dbo.QCR100 AS e ON LTRIM(a.GL_code) = e.Dcode
GROUP BY e.ITEM_DESCRIPTION, e.ITEM_CODE, e.Dcode
How I can alter this view to sum the amount for any duplicated item code and group by item code
Example
ITEM_CODE ITEM_DESCRIPTION DCODE AMOUNT
111200 investments 24000003 1630000000.0000
111600 Other Assets 133000009 1700000000.0000
111701 Leasehold 190010130 1740000000.0000
111705 Furniture 190010036 1750000000.0000
111706 Computer Software 190010141 46995799.1800

Hope you are lloking for this query.
select item_code,ITEM_DESCRIPTION,<br />
(select max(t1.dcode) from qcr100 as t1 where t1.item_code=qcr100.item_code) as dcode,<br />
sum(cast(amount as float)) as amount<br />
from qcr100 <br />
group by item_code,ITEM_DESCRIPTION

I have a customer who refuses to move from an old version of Great Plains 'pre-microsoft' on a novell server using Btrieve 6.15. I am looking for help/advice to make a small VB app that will let them query and print a listing from a specific DAT file. This is being done on a local copy of the data 'not live' on an XP machine. While not new to Vb, I only use it to play and relax 'just don't have the time any more'. I will be using VB 2008 and I guess I need help with the following:
1. What files will I need for the connection to this type of data?
2. What would the connection string look like.
I think those should be my only problems.
Thanks in advance and all help is greatly appriciated.
