I want to create the table as a temporary table in a stored procedure.
What should i do ?

That was not the question you orginally asked. You asked how to replace T1 with a stored procedure.
To create a temporary table in a stored procedure do something like this
CREATE TABLE #MyTempTable(myKey int, someValue varchar(12))
INSERT INTO #MyTempTable ....
At the end of the stored procedure, SQL Server will drop the temp table for you, however you must remember to prefix the table name with '#' which marks it as temporary.
Does this help?

use a UDF (user defined funcation) which can act just like a table. This is the MS recommended method.
select * from my_udf

I have a stored procedure to filtering data as :
CREATE PROCEDURE sp_getFilteredAdvertisement
@advertisementTypeID varchar(20),
@visible varchar(2),
@minDate varchar(40),
@maxDate varchar(40)
AS
declare @SQL as nvarchar(1000)
SET @SQL = 'SELECT [Advertisement].[advertisementID] , [Advertisement].[owner] , [Advertisement].[fileName] , [Advertisement].[link] , [Advertisement].[altText] , ABS([Advertisement].[visible]) AS visible , [Advertisement].[viewCounter] , [Advertisement].[clickCounter] , [AdvertisementType].[name] , [Advertisement].[startDate] FROM [Advertisement] INNER JOIN [AdvertisementType] ON [Advertisement].[AdvertisementTypeID]=[AdvertisementType].[AdvertisementTypeID] WHERE 1=1 '
IF ( LEN( @advertisementTypeID ) > 0 )
BEGIN
SET @SQL = @SQL + 'AND [Advertisement].[advertisementTypeID] = ' + @advertisementTypeID
END
IF ( LEN( @visible ) > 0 )
BEGIN
SET @SQL = @SQL + 'AND [visible] = ' + @visible
END
IF ( LEN( @minDate ) > 0 )
BEGIN
SET @SQL = @SQL + 'AND [startDate] >= ''' + @minDate + ''''
END
IF ( LEN( CAST( @maxDate AS VARCHAR(40) ) ) > 0 )
BEGIN
SET @SQL = @SQL + 'AND [startDate] <= ''' + @maxDate + ''''
END
exec (@SQL)
RETURN
I have a stored procedure to paging found from msdn :
CREATE PROCEDURE northwind_OrdersPaged
(
@PageIndex int,
@PageSize int
)
AS
BEGIN
DECLARE @PageLowerBound int
DECLARE @PageUpperBound int
DECLARE @RowsToReturn int
-- First set the rowcount
SET @RowsToReturn = @PageSize * (@PageIndex + 1)
SET ROWCOUNT @RowsToReturn
-- Set the page bounds
SET @PageLowerBound = @PageSize * @PageIndex
SET @PageUpperBound = @PageLowerBound + @PageSize + 1
-- Create a temp table to store the select results
CREATE TABLE #PageIndex
(
IndexId int IDENTITY (1, 1) NOT NULL,
AdvID int
)
-- Insert into the temp table
INSERT INTO #PageIndex (AdvID)
SELECT
advertisementID
FROM
Advertisement
ORDER BY
advertisementID DESC
-- Return total count
SELECT COUNT(advertisementID) FROM Advertisement
----
select into
-- Return paged results
SELECT
O.*
FROM
Advertisement O,
#PageIndex PageIndex
WHERE
O.advertisementID = PageIndex.AdvID AND
PageIndex.IndexID > @PageLowerBound AND
PageIndex.IndexID < @PageUpperBound
ORDER BY
PageIndex.IndexID
END
How i can put paging procedure in filtering procedure ?

Here is what you can do,
(1) Create this procedure
CREATE PROCEDURE GetDataByPage(
@SqlStr varchar(8000),
@PageSize int,
@CurrentPage int)
AS
DECLARE @FirstRec int, @LastRec int,@dt varchar(10)
BEGIN
-- Initialize variables.
SELECT @FirstRec = (@CurrentPage - 1) * @PageSize
SELECT @LastRec = (@CurrentPage * @PageSize + 1)
SELECT @dt= substring(convert(varchar,rand()),3,10)
-- Create a temp table to hold the current page of data
SELECT @SqlStr = stuff(@SqlStr,charindex(' FROM ',upper(@SqlStr)),6,' INTO tempdb..Paging'+@dt+' FROM ')
EXECUTE (@SqlStr)
-- Add an ID column to count the records
SELECT @SqlStr = 'ALTER TABLE tempdb..Paging'+@dt+' ADD RID numeric(10) IDENTITY PRIMARY KEY'
EXECUTE (@SqlStr)
--Return the total number of records available as an output parameter
SELECT @SqlStr = 'SELECT Count(*) From tempdb..Paging'+@dt
EXECUTE (@SqlStr)
--Select one page of data based on the record numbers above
SELECT @SqlStr = 'SELECT * FROM tempdb..Paging'+@dt+' WHERE RID > '+convert(varchar,@FirstRec)+' and RID < '+convert(varchar,@LastRec)
EXECUTE (@SqlStr)
-- Drop the temporary table
SELECT @SqlStr = 'DROP TABLE tempdb..Paging'+@dt
EXECUTE (@SqlStr)
END
(2) In sp_getFilteredAdvertisement add two more parameters @pageSize, @pageNo
instead of a call to exec(@sql) use
exec GetDataByPage @sql , @pageSize, @pageNo
Hope this helps.

Does anyone have any ideas as to what I am doing wrong. I am new to working with Access and ADO so I know it must be something simple yet I am stumped.

Access makes a file to show that the DB has been locked - perhaps your DB is outside of the directory structure of your web app, and so the ASP.NET user does not have permission to create this file ?

Hi
The problem is the following:
i have an ms access database containing a memo field and i want to insert a new record from within my c# app.
I use an ADO connection and an ADO command.
this is my sql command text:
"INSERT INTO ProductTable (Description) VALUES (' BLA BLA BLA BLA BLA')
All of this seemed to work fine, up until the moment i tried using longer strings.
When adding a string of more than 100 characters in the description field, the command executes normally (no errors), but when looking in the database afterwards shows me the value text is truncated to 100 characters. Editing the value in ms access works flawless, and (and this is the part i dont understand at all), when replacing my ado connection object and command by an ODBC connection object and command, it works just fine, it inserts the complete text without truncation!
Anybody have an idea where this comes from? Should i specify some "long string" property in my connection object? Are there other ways to do this using ADO, because i dont really want to use ODBC, as i read in different places that it is actually deprecated stuff.
thanks

i think it comes from the database restrictions instead...
what database do you use ?
isn't the field [ProductTable].[Description] set to varchar[100] or something like that ?
TOXCCT >>> GEII power
[toxcct][VisualCalc]

|

|
|
it is an access 2000 database, and the field type is "memo".
But even if this were the case, why does it work using the ODBC objects and not using the ADO ones?
|

Use parameterized queries and make the parameter data type adLongVarChar.

Hi,
I am writing an application, which takes a access table < OLEDB 4.0 > provided by ADO.NET connection. I have used both OleDbDataReader as well as OleDbDataAdapter to fetch records from that table, but is providing me only 65536 rows where that table contatains 13000 rows. Neither I can export to it in a text file , nor I can show it to a DataGrid. Since I have to keep those records in some other Repository, please , some one , provide me such a solution to access all the rows..
[ if code placed , please Code it in C# ]
Thank you.

Hello,
I have a Receipts table with fields ID_receipt, WeekNumber, CustomerID. Then I have a Payments table with ID_payment, CustomerID, WeekShouldHaveBeenPaid, WeekPaid.
When I authorize a credit for a customer, I create all the payments on advance (say, 54) and starting the next week, I generate a receipt. Each week one payment will be marked as should-be-paid that week, but only when it really is paid the week number will be stored in the payment row.
I'm trying to migrate some old data to this new format. My problem is that I have the receipts, but I don't have the payments marked when they should be paid. Since I'll make this migration after a week is closed and before the next week is opened, getting those week numbers is easy: I just have to find the first receipt for a customer, mark the first payment with that week, and mark every payment with a consecutive week number until I run out of receipts.
I'm trying to think of a SQL query that could do this for me. Otherwise I'll have to write a little C# program that counts all the receipts and then marks each payment with the corresponding week number. But this is what SQL was made for, so there should be a way.....
Any ideas? Thanks!

Try something like this
You will have to fill in the blanks for connections string etc..
Before some pipes up with "injection attacks security risks etc..."
This is a very basic code to give an idea of how it could work.
=========================
string MySQL = TextBox1.Text; // SQL in the view select * from table
string MyViewName = TextBox2.Text; // The view name on DB
SQLstring = "CREATE VIEW " + MyViewName + " AS " + MySQL
SqlConnection myConnection = new SqlConnection(strConnectSQL);
SqlCommand myCommand = new SqlCommand( SQLstring, myConnection );
try
{
myConnection.Open();
myCommand.ExecuteScalar();
myConnection.Close();
}
catch
{
myConnection.Close();
}

What version of SQL Server are you using ? I know this can be done, as I've connected to a SQL Server instance for a client in the USA, but I'm not sure how it's configured. I know SQL Server 2005 has a lot of new online functionality, but this was SS2000, I am certain.

I've connected directly to a SQL Server 2000 instance over the internet through a VPN connection. It was a bit slower than on the LAN, but that was only to be expected.
You can connect directly too, but even although my SQL Server is patched upto date I wouldn't want to expose it. My firewall log shows several blocked attempts at getting to SQL Server on my machine.

I think There are several ways of doing this but of which i pretty much sure about is running your sql server instance on a server with Static IP. You also need to configure listener ports on the server.
The connection string will look something like this
This is Oledb provider
Provider=sqloledb;Data Source=10.20.50.100,1521;Network Library=DBMSSOCN;Initial Catalog=pubs;User ID=sa;Password=asdasd
if you are using Sql client on a Net framework skip the provider part and rest is same.
I hope this is helpful enough

Create hole in the firewall on a different port than standard SQL server and use NAT to move this each side of the firewall. Also filter the IP address range if possible (providing others have fixed IP addresses.)
