You can use Enterprise Manager (if you have SQL 2000), or SQL Server Management Studio (if you have SQL 2005) to import your data (tables, columns, records) from MySQL.
The wizard to do import/export data should be simple enough to follow.

I've got a fairly simple bit of code which will call a stored proc with the following signature:
dbo.UpdateAssembler (@Id int, @Name char(20), @IsActive bit, @Stamp timestamp) I've created and initialized an SqlCommand object with the appropriate parameters setup, the relevant one in this case "Id" has it's IsNullable property set to true. When I try and execute the command I get the following exception:
Procedure or Function 'UpdateAssembler' expects parameter '@Id', which was not supplied. Hmm  , I've set Id in the previous lines of code (which could be an int or null, the stored proc does something different if Id is null).
Any ideas on what might be causing this exception, note that I have verified the following:
- A parameter by the name of 'Id' does exist in the command's parameters (C# side of things)
- Stored proc does want an Id parameter
- The stored proc works fine if I invoke it through the UI in either VS2005 or the Management Studio.
Sig cops got me...

Okay... But it is looking for a parameter called @Id. Do you supply that parameter?
You might want to post your code - It sounds like a really simple thing like a typo you just need a second pair of eyes to see.

|
|
|

Hmm, I seem to remember the last time I did something like this it didn't want the @ in the SqlParameter's name, but I shall check it, then I'll post the code if not successful since it's taking an age for VS to load.
Sig cops got me...

Ok here's the code (putting the @ in made no difference)
Stored Procedure:
ALTER PROCEDURE dbo.UpdateAssembler (@Id int, @Name char(20), @IsActive bit, @Stamp timestamp) AS
BEGIN
IF EXISTS(SELECT * FROM Assembler WHERE ID = @Id)
IF EXISTS(SELECT * FROM Assembler WHERE (ID = @Id AND Stamp = @Stamp))
UPDATE Assembler
SET Name = @Name,
IsActive = @IsActive
WHERE ID = @Id
ELSE
RAISERROR('Different TimeStamps',10,1)
ELSE
INSERT INTO Assembler
(Name, IsActive)
VALUES (@Name, @IsActive)
ENDBuilding the SqlCommand (in a semi-factory like method thingy-ma-bob):
SqlCommand command = new SqlCommand("UpdateAssembler");
command.CommandType = CommandType.StoredProcedure;
command.Parameters.Add("Id", SqlDbType.Int);
command.Parameters.Add("Stamp", SqlDbType.Timestamp);
command.Parameters["Id"].IsNullable = true;
command.Parameters["Stamp"].IsNullable = true;Executing the command:
updateCommand.Parameters["Id"].Value = item.Id;
updateCommand.Parameters["Stamp"].Value = item.TimeStamp;
updateCommand.ExecuteNonQuery(); Note that certain irrelevant bits have been cut out.
Sig cops got me...
|
|
|
|
|
Could you do a check on item.Id and if it is null replace the value sent as the parameter to DBNull.Value?
|
|
|
|
|
I think I tried that, but it was before I noticed a couple of other mistakes so when I get the chance in a couple of hours I shall do that.
Sig cops got me...

Yes that's cured it, thanks.

If i'm not wrong the SqlParameters are prefixed with @ symbol, and the above lines should be like this:
command.Parameters.Add("@Id", SqlDbType.Int);
command.Parameters.Add("@Stamp", SqlDbType.Timestamp);
command.Parameters["@Id"].IsNullable = true;
command.Parameters["@Stamp"].IsNullable = true;

try following these steps.
1. check the retrieved data for null value, if it is Nothing then
2. set the textbox.Text to empty string or set the controls with suitable values.

I have a problem. Whenever we pass an insert statement against database table the exception can be cathced by using sqlexception parameter. I have done with exception where there is a problem with the primary key because i know the error code it genereates when there is a primary key error. But how can i do the same type of checking when there is an error related to foreign key. Wht is the error code for foreign key related errors. Something like below
try<br />
{<br />
insert into database;<br />
if (success)<br />
then do nothing;<br />
else<br />
check about the cause of exception<br />
}<br />
catch<br />
{<br />
if (primary key exception)<br />
dosomething;<br />
else if(foreign key exception)<br />
dosomething;<br />
else<br />
dosomething;<br />
}
any help will be wellcomed.
Any suggestion is well received. thanx in advance

If I have a problem like this I create a simple test application and experiment. I would create an INSERT that will cause a foreign key violation and see what it returns.
How did you find the value of the Primary Key error in the first place?

It should be telling you that bizdate isn't contained in an aggregate or in a GROUP BY clause. As soon as you roll up results in an aggregate function, everything in the SELECT list must be aggregated or one of the fields used to group.
You'll have to select the value separately, unless you want to show figures grouped for each distinct value in that column, in which case you should use GROUP BY. If you want the latest date/time that this occurred, you could use MAX(bizdate) instead.

I have create a SQL which calculate the daily sale but it will only show 1 day when i run it
<br />
<br />
select t1.supermarket,t1.softline, t1.hardline, (t1.supermarket+t1.softline+ t1.hardline)as TOTAL <br />
from (select (select sum(totalsales+returnamt)as TotalSoft from tot_item <br />
where bizdate='2006-10-1'and (deptcode= 11 or deptcode=12 or <br />
deptcode=13 or deptcode=14 or deptcode= 15 or deptcode= 16 or deptcode= 17 ))as softline,<br />
<br />
(select sum (totalsales+returnamt)as TotalHard from tot_item <br />
where bizdate='2006-10-1'and (deptcode= 21 or deptcode=22 or deptcode=23 or deptcode=<br />
24 or deptcode= 25 or deptcode=26 or deptcode= 27 or deptcode= 28 or deptcode= 29 ) )as hardline,<br />
<br />
(select sum(totalsales+returnamt)as TotalSupermarket from tot_item <br />
where bizdate='2006-10-1' and (deptcode= 30 or deptcode=40 or deptcode=50 or deptcode=<br />
60 or deptcode= 70 or deptcode=80 or deptcode= 90)) as supermarket <br />
)as t1 <br />
<br />
but i want to show like the daily result between day 1- day 15 so i create this SQL but the result not wat i expected, the RESULT should the TOTAL sum of this 15 days.... i want to show 1 by 1 for the daily sale... how?
select t1.supermarket,t1.softline, t1.hardline, (t1.supermarket+t1.softline+ t1.hardline)as TOTAL <br />
from (select (select sum(totalsales+returnamt)as sototal from tot_item <br />
where bizdate<='2006-10-15' and bizdate>='2006-10-01'and (deptcode= 11 or deptcode=12 or <br />
deptcode=13 or deptcode=14 or deptcode= 15 or deptcode= 16 or deptcode= 17 ))as softline,<br />
<br />
(select sum(totalsales+returnamt)as htotal from tot_item <br />
where bizdate<='2006-10-15' and bizdate>='2006-10-01'and (deptcode= 21 or deptcode=22 or deptcode=23 or deptcode=<br />

deptcode=60 or deptcode= 70 or deptcode=80 or deptcode= 90 )) as supermarket <br />

Hmm...it's a bit hard to understand your query as it's too complicated.
You might want to simplify it a bit.
First, use IN instead of deptcode = 14 or deptcode = 15 and so on.
So let's format it first into:
SELECT t1.supermarket,t1.softline, t1.hardline, (t1.supermarket+t1.softline+ t1.hardline) AS TOTAL
FROM
(SELECT (SELECT SUM(totalsales+returnamt) AS TotalSoft
FROM tot_item
WHERE bizdate='2006-10-1' AND deptcode IN (11, 12, 13, 14, 15, 16, 17)) AS softline,
(SELECT SUM(totalsales+returnamt) AS TotalHard
FROM tot_item
WHEREbizdate='2006-10-1' AND deptcode IN (21, 22, 23, 24, 25, 26, 27, 28, 29)) AS hardline,
(SELECT sum(totalsales+returnamt) AS TotalSupermarket
FROM tot_item
WHERE bizdate='2006-10-1' AND deptcode IN (30, 40, 50, 60, 70, 80, 90)) AS supermarket
) AS t1
Now that it's more simplified, I found that you can actually separate softline, hardline, and supermarket into 3 separate queries to save the confusion, and we can use GROUP BY to show the sum for each bizdate.
Query1:
SELECT bizdate, SUM(totalsales+returnamt) AS TotalSoft
FROM tot_item
WHERE deptcode IN (11, 12, 13, 14, 15, 16, 17)
GROUP BY bizdate
Query2:
SELECT bizdate, SUM(totalsales+returnamt) AS TotalHard
FROM tot_item
WHERE deptcode IN (21, 22, 23, 24, 25, 26, 27, 28, 29) AS hardline
GROUP BY bizdate
Query3:
SELECT bizdate, sum(totalsales+returnamt) AS TotalSupermarket
FROM tot_item
WHERE deptcode IN (30, 40, 50, 60, 70, 80, 90) AS supermarket
GROUP BY bizdate
Now in your final query you can link all the total using the following:
SELECT Query1.bizdate, TotalSoft, TotalHard, TotalSupermarket
FROM Query1
LEFT JOIN Query2 ON Query1.bizdate = Query2.bizdate
LEFT JOIN Query3 ON Query1.bizdate = Query3.bizdate
This will return your daily result of the sale.
From there you can specify the 15 days total sum.
If you want to put them all as one big query, here's the query:
SELECT Query1.bizdate, TotalSoft, TotalHard, TotalSupermarket
FROM (SELECT bizdate, SUM(totalsales+returnamt) AS TotalSoft
FROM tot_item
WHERE deptcode IN (11, 12, 13, 14, 15, 16, 17)
GROUP BY bizdate) AS Query1
LEFT JOIN (SELECT bizdate, SUM(totalsales+returnamt) AS TotalHard
FROM tot_item
WHERE deptcode IN (21, 22, 23, 24, 25, 26, 27, 28, 29) AS hardline
GROUP BY bizdate) AS Query2
ON Query1.bizdate = Query2.bizdate
LEFT JOIN (SELECT bizdate, sum(totalsales+returnamt) AS TotalSupermarket
FROM tot_item
WHERE deptcode IN (30, 40, 50, 60, 70, 80, 90) AS supermarket
GROUP BY bizdate) AS Query3
ON Query1.bizdate = Query3.bizdate
I hope the explanation above helps in your problem.
Note: I'm blind coding, so please check the syntax for me, ok 
Cheers,
Edbert

actaully where do i put the date that i want them to show on??
like
where bizdate<='2006-10-15' and bizdate>='2006-10-01which it will show between '2006-10-01' and'2006-10-15'

Which query did you run? Does each query run?
You can put the WHERE condition at the end of the query, before the GROUP BY if there is any.

Oh. Scratch that. I forgot to delete the AS hardline and AS supermarket.
The code below should (hopefully) work 
(Please delete the AS hardline and AS supermarket in Query2 and Query3 respectively)
SELECT Query1.bizdate, TotalSoft, TotalHard, TotalSupermarket
FROM (SELECT bizdate, SUM(totalsales+returnamt) AS TotalSoft
FROM tot_item
WHERE deptcode IN (11, 12, 13, 14, 15, 16, 17)
GROUP BY bizdate) AS Query1
LEFT JOIN (SELECT bizdate, SUM(totalsales+returnamt) AS TotalHard
FROM tot_item
WHERE deptcode IN (21, 22, 23, 24, 25, 26, 27, 28, 29)
GROUP BY bizdate) AS Query2
ON Query1.bizdate = Query2.bizdate
LEFT JOIN (SELECT bizdate, sum(totalsales+returnamt) AS TotalSupermarket
FROM tot_item
WHERE deptcode IN (30, 40, 50, 60, 70, 80, 90)
GROUP BY bizdate) AS Query3
ON Query1.bizdate = Query3.bizdate

in the sqlconnection.open the nullrefrence exception occures but
when i define myself this exception dosn't occure.
