Thanks for answer but i dont know why it is not working in my way.
I have a table named "DebitsAndCredits" which has fallowing columns
AccountNumber char(12)
DebitCredit bit
Amount money
I have the same table in two databases which are MB0001 and MB0002
I would like to join them in a one result set.I write
SELECT DISTINCT (AccountNumber ) ,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =0 AND m.AccountNumber =f.AccountNumber ) as Credit,,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =1 AND m.AccountNumber =f.AccountNumber ) as Debit
FROM DebitsAndCreditsf Order BY AccountNumber
UNION
SELECT DISTINCT (AccountNumber ) ,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =0 AND m.AccountNumber =f.AccountNumber ) as Credit,
(SELECT SUM(Amount ) FROM DebitsAndCredits m
WHERE m.DebitCredit =1 AND m.AccountNumber =f.AccountNumber ) as Debit
FROM DebitsAndCreditsf Order BY AccountNumber
What do u offer for me?

Try this:
SELECT AccountNumber,
SUM(CASE DebitCredit=0 THEN Amount ELSE 0 END) as Credit,
SUM(CASE DebitCredit=1 THEN Amount ELSE 0 END) as Debit
FROM MB0001..DebitsAndCredits
ORDER BY AccountNumber
GROUP BY AccountNumber
UNION
SELECT AccountNumber,
SUM(CASE DebitCredit=0 THEN Amount ELSE 0 END) as Credit,
SUM(CASE DebitCredit=1 THEN Amount ELSE 0 END) as Debit
FROM MB0002..DebitsAndCredits
GROUP BY AccountNumber
ORDER BY AccountNumber

Hi all,
I have a problem for data transactions across two databases.
That is one object's data is comprised of two tables from
two different databases. I can perform rollback and commit within
one database. But for this case, how can I perform rollback and commit
across two databases(for two different SQL connections) for the object ?
Thanks

You need to use a two phase commit mechanism. What database are you using?

I am trying to execute a crosstab query in SQL Server 2000, but alot of the columns display null values for every row. This is an example of what I am getting:
Test | Prompt | 0412-0001 | 0412-0002 | 0412-0003
-------------------------------------------------------
BTEX | Benzene | NULL | NULL | ND
ph VALUE | ph VALUE | NULL | NULL | 7
And what I want displayed is the following:
Test | Prompt | 0412-0003
-------------------------------
BTEX | Benzene | ND
ph VALUE | ph VALUE | 7
(I think the formatting is screwing up with the columns, but | indicates a column separator)
I am using the stored procedure found here:
http://www.sqlteam.com/item.asp?itemID=2955[^]
I do not know much about SQL programming and I was wondering if there is a way to modify this stored procedure to eliminate all columns that contain no data.

 hi,dear buddies:
I have finished some instroductory books on SQL, but need some practice.
Do you guys have any suggestions on where I can find some good exerciese or quizs or real-world cases I can play with? OR any exercises based on the pre-installed database in SQL-server2000 (such as pub,northwind)?
Thanks a lot.
Waiting online !

I currently strip out any quote marks from data input (and many other characters) when sending data to the database but would like the user to be able to enter quote marks if they wish.
I use mostly stored procedures to update data but often compose sql on the fly for ad hoc searching. Can anyone tell me how I should be handling the characters which are used in T-SQL such as ' and %
Thanks in advance - Dave

Thnx Colin.It does help a lot..
One more thing.I am working C++.Net and i want to organise the Connection to the database and the results of a specific SQL Statement through the adapter and the table in a single class... TO BE MORE SPECIFIC
#pragma once
class DBConn
{
public:
DBConn(void);
~DBConn(void);
public:
String* Type;
int Cost;
public:
String* FigureUserType(String* SenderNo)
{
SqlConnection * myConn = new SqlConnection(S"data source=(local);",S"integrated security=true;initial catalog=SMSCenter");
myConn->Open();
SqlDataAdapter * daResults = new SqlDataAdapter();
daResults->SelectCommand=new SqlCommand("SELECT Type FROM Subscribers WHERE PhoneNumber=@SenderNo",myConn);
SqlParameter* SenderParam=new SqlParameter();
//Set Parameter Properties
SenderParam = daResults->SelectCommand->Parameters->Add(
new SqlParameter("@SenderNo", SqlDbType::VarChar));
SenderParam->Value=SenderNo;
SenderParam->SourceVersion = DataRowVersion::Current;
//Create The Dataset to Fill
DataSet * dsresults = new DataSet();
//Fill the DataSet
daResults->Fill(dsresults,"Apotelesmata")
//Create The datarow
DataRow* drResults=new DataRow();
for(int i=0;>= dsResults->Tables->Item ["Apotelesmata"]->Rows->Count;i++)
{
myAuthorRow = myDataSet->Tables->Item["Apotelesmata"]->Rows->Item[i];
String* RetType=myAuthorRow->Item ["SenderNo"]->ToString ());
}
return RetType // Suppose we have only one Result
};
But I don't know where in the class i should declare the following...
using namespace System::Data; // Generic ADO.NET definitions, such as DataSet
using namespace System::Data::SqlClient; // SQL Server data provider definition
namespace system and so goes on...
PLS HELP

I am using ADO.NET to access a SQL Server 2000 database in which there is a table Orders whose primary Key 'OID' is incremented automatically, so when I insert a new order I don't specify its OID. However, I need to know the OID of the inserted order to add items to it. Isn't there a function or something to do that ? Thank you.

You can use IDENT_CURRENT('table_name') to get the last automatically generated value inserted into the table that you specify.
Probably the best way to do this is to create a stored procedure to do the increment and then get the value
CREATE PROCEDURE InsertOrder
-- Set parameters for the values to be inserted here
AS
INSERT INTO Orders( column_names )
VALUES ( parameters containing the data to be inserted );
SELECT IDENT_CURRENT('Orders');
GO
Then in your .NET application you can use the SqlCommand.ExecuteScalar() to get the value out.
Does this help?

Hi All,
I'm working on a c# application that suppose to store and retrieve images in the sql server database. By choosing a column of type image, it's size is defaulted to 16bytes but images usually are larger than that. How can I increase the size of an image column so that it can hold images of some 10+kb? Plz answer and oblige.
Thanks
|

An image column can hold up to 2GB of data, IIRC. As Colin says, the 16 byte value is the pointer to where the data actually lives. Image data is not held on the same data page as the rest of the row - you should be aware that more I/O will occur if you use text, ntext or image columns.
Having said that SQL Server has a feature 'text in row' which allows you to specify that up to a certain amount of data will be placed in the row itself, not on separate pages.
Stability. What an interesting concept. -- Chris Maunder

As a work around u can save the path to the images which will reduce the size of the db and also reduces the effort to handle images in sql.
i hope this helps.

I have a VB.Net windows app that retrieves data from 3 different tables. The SQL command uses a 3 table join. The results from the query is filled into a datatable and later populated into a combobox.
The SQL uses the values from a date field inside a text field, for example, 01-15-2005. So, each time I submit the subroutine it executes the SQL command and VB.Net code to retrieve the required data. The date field changes according to the user’s needs.
There’s no consistency when the error pops up.
The error message I’m getting when it executes, da.Fill(dataTable), “There’s no row at position 0”,. The information I’m on the stack track is as follow: Calling SQLDisconnect --- OleDB UnInitialize not called!!!
Connection Object destroyed
If I copy the sql into a sql query tool it does retrieve the required data according to the date field.
Here’s a sample of the subroutine:
cmdQueryINVOICE = _
"SELECT PAYITEM.TRANSACT_NUMBER, " _
& "PAYITEM.ACCOUNT_NUMBER, " _
& "PAYITEM.PAY_DATE, " _
& "LSEINVH.INVOICE_NUMBER " _
& "FROM LSEINVH, PAYITEM, TRANSHDR " _
& "WHERE " _
& " LSEINVH.INVOICE_NUMBER > '" & 75000 _
& "' AND LSEINVH.STATUS <> '" & sStatus _
& "' AND LSEINVH.INVOICE_NUMBER = TRANSHDR.INVOICE_NUMBER " _
& " AND PAYITEM.PAY_DATE > '" & InvoiceDates.StartDate _
& "' AND PAYITEM.PAY_DATE < '" & InvoiceDates.EndDate _
& "' AND PAYITEM.COMPANY = '" & sCompany _
& "' AND PAYITEM.TRANSACT_NUMBER = TRANSHDR.TRANS_NUMBER order by PAYITEM.PAY_DATE desc "
Dim sqlQuery As OleDbCommand = connDf.CreateCommand
Dim dtInvDate As New DataTable()
Dim iInvCnt, x As Integer
Dim sUnitQuery As String
Dim daInv As New OleDbDataAdapter()
Try
daInv = New OleDbDataAdapter(cmdQueryINVOICE, connDf)
daInv.Fill(dtInvDate)
Dim LoopRow As Data.DataRow
Dim test As String = dtInvDate.Rows.Item(0).ToString
For Each LoopRow In dtInvDate.Rows
cboInvoice.Items.Add(LoopRow.Item("INVOICE_NUMBER").ToString + " " + LoopRow.Item("PAY_DATE"))
Next
Catch e As Exception
Dim errMsg As String = e.Message
Finally
connDf.Close()
End Try
Thanks, for any help!
