The command is called raiserror. If you do a seach on it you will find plently of examples. If you want to quit a stored procedure and you don't want to use raiserror with a high enough severity then you the Return key word to exit the procedure.
Hope that helps.

I am developing a solution in C# on top of ADO.NET. I am using MS Access as my data store. My requirement is that i have to insert a Unicode string containing Arabic characters into the database. So following is the INSERT command
INSERT INTO ClauseTranslations (Translation) VALUES('اردو کی ایک مثال')
So thats it. Now this query executes very well in the MS Access environment but simply fails when executed from the C# application using the ADO.NET classes. The error message is
"Syntax Error in INSERT Statement"
Can anyone guide me whats wrong and where is it wrong?

It is possible that your field name (Translations) is a keyword for the Jet Engine SQL implementation. Try enclosing it in square brackets [Translation] to avoid interpretation as a keyword.
If that fails, implement the insert using a parameterized insert stored procedure (querydef in Access Lingo) and use an SQLCommand to execute it from C#. This almost always works, as SQL syntax is interpreted at the database, and data values are cleanly encapsulated, avoiding any parsing problems.
Using stored procedures and commands also makes your application far less vulnerable to sql injection attacks.

Hey guys,
I am trying to write a C# program to import data from an Excel spreadsheet to a Sql table using a stored procedure.
So, I've created the connection objects:
OleDbConnection XLcon = new OleDbConnection(
@"Provider = Microsoft.Jet.OLEDB.4.0; Data Source = D:\Desktop\OA.xls;"
+ @"Extended Properties = Excel 8.0;");
SqlConnection SQLcon = new SqlConnection(
@"Data Source = (local); Integrated Security = SSPI; Initial Catalog = WebData");
And the Command Objects:
SqlCommand SQLcmd3 = new SqlCommand();
SQLcmd3.CommandText = "ImportOA";
SQLcmd3.CommandType = CommandType.StoredProcedure;
SQLcmd3.Connection = SQLcon;
OleDbCommand XLcmd = new OleDbCommand("SELECT [Date], [Order Application], "
+ "[Demand Orders], [Demand Units], [Demand Net], [Demand Gross], "
+ "[Demand Freight], [Demand Tax], [Demand Amount], [Demand Product Promo], "
+ "[Demand Ship Promo], [Fulfillment Units], [Fulfillment Net], "
+ "[Fulfillment Freight], [Fulfillment Tax], [Fulfillment Amount], "
+ "[Fulfillment Product Promo], [Fulfillment Ship Promo], [Return Orders], "
+ "[Return Units], [Return Net], [Month], [Quarter], [Year], [Week #], "
+ "[Return Amount] FROM [Excel$]", XLcon);
Set up the parameters:
SQLcmd3.Parameters.Add("@Date", SqlDbType.SmallDateTime);
SQLcmd3.Parameters.Add("@OrderApplications", SqlDbType.VarChar,10);
.
.
.
SQLcmd3.Parameters.Add("@ReturnAmount", SqlDbType.Money);
And then tried to import the data:
XLcon.Open();
OleDbDataReader XLread = XLcmd.ExecuteReader();
while (XLread.Read())
{
SQLcon.Open();
SQLcmd3.Parameters["@Date"].Value = XLread[0];
SQLcmd3.Parameters["@OrderApplications"].Value = XLread[1];
.
.
.
SQLcmd3.Parameters["@ReturnAmount"].Value = XLread[25];
SQLcon.Close();
}
XLcon.Close();
XLread.Close();
The code runs fine but it does not import anything into the table. The spreadsheet has data in it and I have verified that the Store procedure works so why can't I get the values in the spreadsheet into the table?
Thanks,
Bryan

I'm not sure what you are trying to do here, but it doesn't look correct.
you have created a command query containing a select statement that specifies a list of fields to be selected from the worksheet named Excel$. You read the results of that query into a command object that is linked to a stored proc in SQL server somewhere. You open a connection, set command parameters to row values read from excel and then close the connection (do you execute the command first?).
First, I would open and close the connection outside of the reader while loop, and just execute SQLcmd3 at the bottom of the loop. Close and dispose of the connection (and command) after the while loop.
Set a breakpoint at one of the lines that sets a parameter value and verify that you are really returning data from the sheet.
Good luck

Hi, I have to show a filesystem on a page. The information is stored in a table where I have ID(PK), Name, Parent, Order
001, Node1, NULL, 1
002, Node2, NULL, 2
003, Node3, 001, 1
004, Node4, 001, 2
005, Node5, 002, 2
I need to display the results as it should be seen:
+Node1
Node3
Node4
+Node2
Node5
The query I have is like this:
SELECT A.*
FROM TableFS A
LEFT OUTER JOIN TableFS B
ON A.ParentID = B.ItemID
ORDER BY A.ParentID, B.Order
The result is similar to what I should get, but similar is not enough... at least it's what they tell me... 
If anyone can help... 
Thanks...!

Sorry, but this is not even close. Items without parents have value in NULL, so your querry dosen't take those nodes in charge, and gives me duplicated values anyway.
Thanks for your time

I have a central database in a server computer(In sql express 2005).
Two or more computers can connect to the central database.When a terminal computer is doing some operation on some data, how can i ensure that the other terminal
in the same network doesnot change the data at the very same moment?

SQL Server automatically ensures that data modification statements (INSERT, UPDATE, DELETE) are atomic - a statement that affects multiple rows will either modify all of them, or none (if some error occurs, the partial changes will be rolled back).
If you need to execute multiple statements in the same logical operation, and have the results consistent, you can use a transaction. If submitting all the statements in a single batch, or in a stored procedure, you can use the BEGIN TRANSACTION/COMMIT TRANSACTION/ROLLBACK TRANSACTION statements. If you can't execute it all in one batch, or need to call multiple stored procedures, use a client-side transaction (e.g. SqlConnection.CreateTransaction in .NET languages)
There are a number of transaction isolation levels which control which updates from other users can appear between two SELECT statements in the same transaction. Basically, READ COMMITTED (the default) allows changes to be made between two SELECTs - the second statement may see results that another, completed, transaction has made. REPEATABLE READ prevents updates and deletes until your transaction is committed. SERIALIZABLE also prevents inserts that would change your resultset.
Transactions using the built-in transaction features should be kept short. Holding a transaction open for too long prevents other users getting work done. If you need your application to allow users to read a record, make changes to it over a period of time, then eventually commit the change, you need to either come up with a manual record-locking scheme, or somehow check to see if changes have been made since the data was read and either automatically merge the changes made by each user or simply alert the user that the database has been changed.
One of the simplest ways to detect that the data has changed since being read is to use a rowversion column, which changes every time the row is updated.

if you use a simple select like this, you could get the wrong record when by many users at the same time, instead you can use:
select * from Customer where CustID = SCOPE_IDENTITY()
