You don't search a database with the IndexOf() method, that is for arrays.
I suspect that what you are tying to do is to use the controls to select an item so that you can then select the appropriate data from the database. Is this the case? You need to describe what you are doing more clearly so we can help you better.

I want to be able to type a string into an input box or text box that would match itself with a field in the database then show me the results in a listbox. Then by clicking on the list box pull up the entire record.

I am working on an asp script that pulls data from ms sql. In one part, it pulls the days of the week that an event occurs on. If I do something like this:
select dayofweek from schedule where id=5
I get:
---------
dayofweek
---------
M
---------
T
---------
W
---------
What I need is a sql statement that does something like this:
---------
dayofweek
---------
M,T,W
---------
Is there a way to select them into one record like this even though they are stored in multiple rows in the table?
Thanks,
Jim

Try this T SQL script (you ca make a SQL Server function)
--parameter @id
DECLARE @id INT
SET @id = 5
DECLARE @ssum NVARCHAR(255)
DECLARE @dayofweek NVARCHAR(25)
SET @ssum = ''
DECLARE crs CURSOR FOR SELECT DAYOFWEEK FROM schedule WHERE ID = @id
OPEN crs
FETCH NEXT FROM crs INTO @dayofweek
WHILE( @@FETCH_STATUS = 0 )
BEGIN
SET @ssum = @ssum + ',' + @dayofweek
FETCH NEXT FROM crs INTO @dayofweek
END
CLOSE crs
DEALLOCATE crs
IF( LEN(@ssum) != 0 )
SET @ssum = SUBSTRING(@ssum,2,255)
PRINT @ssum

I need to do exactly the same thing, but my result needs to print in a textbox in a SQL Server 2000 Reporting Services Report. I created a function in the Custom Code area for the report, but I get the message: "Statement is not valid inside a method." Can you tell me how to make your code work in Reporting Services?

I want to say that
you must create a "user defined function" (T SQL function)
like this
CREATE FUNCTION SSum (@id INT)
RETURNS NVARCHAR(255) AS <br />
BEGIN <br />
<br />
DECLARE @ssum NVARCHAR(255)<br />
DECLARE @dayofweek NVARCHAR(25)<br />
SET @ssum = ''<br />
<br />
DECLARE crs CURSOR FOR SELECT DAYOFWEEK FROM schedule WHERE ID = @id<br />
OPEN crs<br />
<br />
FETCH NEXT FROM crs INTO @dayofweek<br />
WHILE( @@FETCH_STATUS = 0 )<br />
BEGIN<br />
SET @ssum = @ssum + ',' + @dayofweek<br />
FETCH NEXT FROM crs INTO @dayofweek<br />
END<br />
<br />
CLOSE crs<br />
DEALLOCATE crs<br />
<br />
IF( LEN(@ssum) != 0 )<br />
SET @ssum = SUBSTRING(@ssum,2,255)<br />
<br />
RETURN @ssum<br />
<br />
END
After, built your report on a SELECT query using SSum function like this:
<br />
SELECT DISTINCT ID , dbo.SSum(id) AS Days<br />
FROM schedule<br />

I was able to put your code into a stored procedure, then call the string from there. It worked!! The user defined function would probably work as well. Your code has saved me hours of work!

I have found the xp_startmail, xp_sendmail, and the xp_stopmail. I have gotten it to run and send mail to myself. My problem is, is there anyway to get it to send from my current database. I have to be in the Master to get them to work. If I try to work out of my own DB than it says it cannot find the stored procedures. I want to know if there is anyway to map to my DB that I am using, or copy the mail stored procedures into my DB.
Thank You

I solved my own problem... In the argument, you have to use "exec DBname.dbo.SP name". It is working for me!

Hello All!
I have some problem when i try Update record in opened Recordset in VB Script. Windows 2000Pro SP4,MDAC2.7SP1,VBS5.6,SQL2000SP3.
Table:
CREATE TABLE [dbo].[Table1] (
[ID] [int] IDENTITY (1, 1) NOT NULL ,
[Title] [varchar] (255) NULL ,
) ON [PRIMARY]
Table have an auto-incriment ID and 1 varchar field.
After execute Update method record must have filled ID field.
But in following example this did't appear:
....
Set Conn2 = CreateObject ("ADODB.Connection")<br />
Conn2.Open "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Test;Data Source=127.0.0.1;Use Procedure for Prepare=1;Auto Translate=True;Packet Size=4096;Workstation ID=W2000;Use Encryption for Data=False;Tag with column collation when possible=False", "","" <br />
Set rs2 = CreateObject ("ADODB.Recordset")<br />
rs2.Open "Table1", Conn2,adOpenKeyset, 3, adCmdTable<br />
Rs2.AddNew<br />
Rs2("Title") = "Some text"<br />
Rs2.Update<br />
WScript.StdOut.WriteLine "Added New Record: " &Rs2("ID")& " " &Rs2("Title") ' ID = NULL!!!....
Somebody can me explain why this did not work in VBS and CORRECTLY executed and UPDATED in MCVC 6.0 SP4.
Thank for all who can help me understand this situation.

SELECT * INTO T2 FROM T1
fills T2 with T1 records.
How can I use an stored procedure that returns records , instead T1
?
thanks.

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.

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.
