In Dot net 2.0 we change using SQLDataSource to Conect with SQLDB.
Now for My case ,the Select SQL is dynamic when differnece user and parameters to the page, So if I want to Update the data input by user,then I must give Update/insert/delelte SQL to SQLDatasource's InsertCommand /UpdateCommand/DeleteCommand .
How to Generate the Insert/update/delete command for the SQLDataSource ? as in dot net 1.1 can use SQLCommandBuilder to generate it,but SQLCommandBuilder just support DataAdeptor not for SQLDataSource, Could any body know how to do it when the SelectCommand is dynamic and need to update data back to DB after edit?
thanks a lot.

Would it be possible to retrieve a "dynamically" named field from a table by using an input parameter?
For example, if a table has fields named Semester1, Semester2, Semester3, Semester4, and I was lazy and only wanted to create one stored procedure for all semesters could I do the following...
ALTER PROCEDURE u_sp_x
@semester int
AS
Select Semester@semester
From ThisTable
Just curious.
Thanks,

HiMy problem is as follows:I need to transmit data between two databases on the same server, but Ihave to use dynamic database names (they must be configurable). Forexample I need to achive sth like that:insert into [database1].[dbo].[table1](select columns from [table2])when database1 is not known at implementation stage.I know I can use EXEC @t_sql_code, but I wonder if there is any otherway? (OPENROWSET doesn't seem to suit my needs)Thanks in advanceAmfi

OK, I'm trying to add some audit type information to a set of tables in my database. This involves adding 2 columns and sticking some data into those two columns. The columns themselves are added successfully, but I'm having troubles sticking any data into them - I'm getting a lot of errors. What I want to do is put a single character code in one column, and a datetime in the second. Here's the SQL I'm trying...
Code Snippet
SELECT @SQL = N'UPDATE ' + QUOTENAME(@TableName) + ' ' +
N' SET TRANSACTION_CODE = ''' + @TxCode +
N''', EFFECTIVE_DATE = ''' + @TxDateTime + ''';'
SELECT @Params = N'@TxCode varchar(1), @TxDateTime datetime'
EXEC sp_executesql @SQL, @Params, @TxCode, @TxDateTime
But this errors out with:
Msg 241, Level 16, State 1, Line 64
Conversion failed when converting datetime from character string.
I tried changing the datetime column to varchar, and CONVERT(varchar(30),@TxDateTime). That gets rid of the above error, but replaces it with the following (twice, I might add - one for each column?):
Msg 213, Level 16, State 1, Line 1
Insert Error: Column name or number of supplied values does not match table definition.
Any help is appreciated - let me know if you need more info.

Hi,
I rewrote my working Sql statement to prevent Sql Injections. I copied some code I used in another project but this time I can't get it to work, possibly because it's an update statement and not an Insert one, which I used before.
Sorry for the boring question, but does anyone have a clue what's wrong with the syntax?
Here's the original code (I changed the parameter names for clarity and security):
Dim conn As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString) Dim strSQL As String = "Update MyTable Set " & typ & num & " = '" & pname & "' WHERE personID = " & fid Dim cmd As SqlCommand = New SqlCommand(strSQL, conn)
Here's the code from codebehind:
Dim conn As SqlConnection = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("MyConnectionString").ConnectionString) Dim strSQL As String = "Update MyTable Set (" & typ & num & ") Values (@" & typ & num & ") WHERE personID = " & fid Dim cmd As New SqlCommand(strSQL, conn) With cmd.Parameters .Add(New SqlParameter("@" & typ & num, pname)) End With TestLabel.Text = strSQL & " " & pname cmd.Connection.Open() cmd.ExecuteNonQuery() cmd.Connection.Close()
Here's my test message; first the sql, then the new string to be inserted:
Update MyTable Set (picturename) Values (@pname) WHERE personID = 2 2_adin.jpg
Here's my error code:
Line 1: Incorrect syntax near '('. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: Line 1: Incorrect syntax near '('.
Source Error:
Line 489: TestLabel.Text = strSQL & " " & pnameLine 490: cmd.Connection.Open()Line 491: cmd.ExecuteNonQuery()Line 492: cmd.Connection.Close()Line 493: End If
I could understand it if I'd get an error in VWD Express for using dynamic variables, but they work correctly in the text message so I'm clueless. Any help is deeply appreciated!

I'm trying to generate an update statement based off select statement results. A very basic example,
SELECT ListID FROM DListing WHERE Status = 2Results return 3 rows.
1234
2345
3456
How can I take those results and turn them into WHERE criteria for UPDATE statement?
Generated UPDATE statement should look like this.
UPDATE DListing SET Status = 1 WHERE ListID IN (1234,2345,3456)
I have started by creating a temp table to hold my SELECT results, but I don't know how to get those results into format for IN condition. Right now I get 3 UPDATE statements with 1 ListID in each IN condition.
CREATE TABLE #TempStatusUpdate(ListID INT)
INSERT INTO #TempStatusUpdate
SELECT ListID FROM DListing WHERE Status = 2
SELECT 'UPDATE DListing SET Status = 1 WHERE ListID IN (' + CONVERT(VARCHAR(30),ListID) + ') AND Status = 2'
DROP TABLE #TempStatusUpdate

I am trying to incrementally update a Cube to get near real time data for the end users. Currently we have a Sql server agent Job that does a FullProcess on the Cube. The Cube consists of a single Measure group which is simply one named query containing inner joins of all the dimensions and fact tables in the underlying relational database. The end users have a lot to upload during the day and they would like us to refresh the cube (near real time) to ensure the adjustments are loaded so that they could reconcile their daily PnLs. We have a MeasureId added which is an auto increment column in the Measures table.
I am trying to schedule the below XMLA query in Sql server agent Job and schedule it to run every 15mins or even less (if possible). However it seems to be not working and keep throwing all sorts of errors.
DECLARE @LastMeasureId AS INT, @myXMLA nvarchar(max)
SELECT @LastMeasureId = "[Measures].[Maximum Measures Id]" FROM
OpenRowset(
'MSOLAP',
'DATA SOURCE=L68F728326574; Initial Catalog=GMDR;',
'SELECT NON EMPTY {[Measures].[Maximum Measures Id]} ON COLUMNS FROM [GMDR]');
[Code] ....

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

Hi Craig/Kamal,
I got your email address from your web cast. I really enjoyed the web cast and found it to be
very informative.
Our company is planning to use SSIS (VS 2005 / SQL Server 2005). I have a quick question
regarding the product. I have looked for the information on the web, but was not able to find
relevant information.
We are getting Source data from two of our client in the form of Excel Sheet. These Excel sheets
Are generated using reporting services. On examining the excel sheet, I found out that the name
Of the columns contain data itself, so the names are not static such as Jan 2007 Sales, Feb 2007 Sales etc etc.
And even the number of columns are not static. It depends upon the range of date selected by the user.
I wanted to know, if there is a way to import Excel sheet using Integration Services by defining the position
Of column, instead of column name and I am not sure if there is a way for me to import excel with dynamic
Number of columns.
Your help in this respect is highly appreciated!
Thanks,
Hi Anthony, I am glad the Web cast was helpful.
Kamal and I have both moved on to other teams in MSFT and I am a little rusty in that area, though in general dynamic numbers of columns in any format is always tricky. I am just assuming its not feasible for you to try and get the source for SSIS a little closer to home, e.g. rather than using Excel output from Reporting Services, use the same/some form of the query/data source that RS is using.
I suggest you post a question on the SSIS forum on MSDN and you should get some good answers.

Hi,
I have a need to display on screen AND email a pdf report to email addresses specified at run time, executing the report with a parameter specified by the user. I have looked into data driven subscriptions, but it seems this is based on scheduling. Unfortunately for the majority of the project I will only have access to SQL 2005 Standard Edition (Production system is Enterprise), so I cannot investigate thoroughly.
So, is this possible using data driven subscriptions? Scenario is:
1. User enters parameter used for query, as well as email addresses.
2. Report is generated and displayed on screen.
3. Report is emailed to addresses specified by user.
Any tips on how to get this working?
Thanks

If anyone could confirm...
SQL Server 2000 SP4 to multiple SQL Server 2005 Mobile Edition on PDAs. My DB on SQL2k is published with a single dynamic row filter using host_name() on my 'parent' table and also join filters from parent to child tables. The row filter uses joins to other tables elsewhere that are not published to evaluate what data is allowed through the filter.
E.g. Published parent table that contains suppliers names, etc. while child table is suppliers' products. The filter queries host_name(s) linked to suppliers in unpublished table elsewhere.
First initial sync with snapshot is correct and as I expected - PDA receives only the data from parent (and thus child tables) that matches the row filter for the host_name provided.
However - in my scenario host_name <--> suppliers may later be updated E.g. more suppliers assigned to a PDA for use or vice versa. But when I merge the mobile DB, the new data is not downloaded? Tried re-running snapshot, etc., no change.
Question: I thought the filters would remain dynamic and be applied on each sync?
I run a 'harmless' update on parent table using TSQL e.g. "update table set 'X' = 'X'" and re-sync. Now the new parent records are downloaded - but the child records are not!
Question: I wonder why if parent records are supplied, why not child records?
If I delete existing DB and sync new, I get the updated snapshot and all is well - until more data added back at server...
Any help would be greatly appreciated. Is it possible (or not) to have dynamic filters run during second or subsequent merge?

I have a Stored Procedure for processing a Bill of Material.
One column on the Assembly Table is a Function Name that contains some busniess rules.
OK, now I'm doing a Proof of Concept and I'm stumped.
Huuuuh!
I will ultimately have about 100 of these things. My plan was using Dynamic SQL to go execute the function.
Note: The function just returns a bit.
So; here's what I had in mind ...
if isnull(@FnNameYN,'') <> ''
exec spinb_CheckYN @FnNameYN, @InvLineID, @FnBit = @FnBit output
CREATE PROCEDURE dbo.spinb_CheckYN
@FnNameYN varchar(50),
@InvLineID int,
@FnBit bit output
AS
declare @SQL varchar(8000)
set @SQL = '
if dbo.' + @FnNameYN + ' (' + convert(varchar(31),@InvLineID) + ')) = 1
set @FnBit = 1
else
set @FnBit = 0'
exec (@SQL)
GO
Obviously; @FnBit is not defined in @SQL so that execution will not work.
Server: Msg 137, Level 15, State 1, Line 4
Must declare the variable '@FnBit'.
Server: Msg 137, Level 15, State 1, Line 5
Must declare the variable '@FnBit'.
So; is there a way to get a value out of a Dynamic SQL piece of code and get that value INTO my OUTPUT variable?
My many thanks to anyone who can solve this riddle for me.
Thank You!
Sigh: For now, it looks like I'll have a huge string of "IF" statements for each business rule function, as follows:
Hopefully a better solution comes to light.
------ Vertical Build1 - Std Vanes -----------
if @FnNameYN = 'fnb_YN_B1_14'
BEGIN
if dbo.fnb_YN_B1_14 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END
------ Vertical Build1 - Scissor Vanes -----------
if @FnNameYN = 'fnb_YN_B1_15'
BEGIN
if dbo.fnb_YN_B1_15 (convert(varchar(31),@InvLineID) ) = 1
set @FnBit = 1
else
set @FnBit = 0
END
.

I have a requirment which i have partly accomplished , but could not get through completely
i have a file which comes in a standard format ending with date and seq number ,
suppose , the file name is abc_yyyymmdd_01 , for first copy , if it is copied more then once the sequence number changes to 02 and 03 and keep going on .
then i need to transform those in to new file comma delimited destination file with a name abc_yyyymmdd,txt and others counting file counting record abc_count_yyyymmdd.txt. and move it to a designated folder. and the source file is then moved to archived folder
what i have taken apprach is
script task select source file --------------------> data flow task------------------------------------------> script task to destination file
dataflow task -------------------------> does count and copy in delimited format
what is happening here is i can accomlish a regular source file convert it to delimited destination file --------> and move it to destination folder with script task .
but cannot work the dynamic pick of a source file.
please advise with your comments or solution you have

sample file name:
Unique identifier + query output + systemdate();
The expression is looking like this.

-- user filepath is a variable from ssis package. File name is the output from SQL query. using script task i have assigned the values to @[User::FileName] .
When I debugged the script task the value getting properly but same variable am using for Flafile destination. but its not working.

I have created a dynamic SQL program that returns a range of columns (1 -12) based on the date range the user may select. Each dynamic column is month based, however, the date range may overlap from one year to another. Thus, the beginning month for one selection may be October 2005, while another may have the beginning month of January 2007.
Basically, the dynamic SQL is a derived Pivot table. The problem that I need to resolve is how do I now use this dynamic result set in a Report. Please keep in mind that the name of the columns change based on the date range select.
I have come to understand that a dynamic anything is a moving target!
Please advise.

What's up with this?
This takes like 0 secs to complete:
update xxx_TableName_xxx
set d_50 = 'DE',modify_timestamp = getdate(),modified_by = 1159
where enc_id in
('C24E6640-D2CC-45C6-8C74-74F6466FA262',
'762E6B26-AE4A-4FDB-A6FB-77B4782566C3',
'D7FBD152-F7AE-449C-A875-C85B5F6BB462')
but From linked server this takes 8 minutes????!!!??!:
update [xxx_servername_xxxx].xxx_DatabaseName_xxx.dbo.xxx_TableName_xxx
set d_50 = 'DE',modify_timestamp = getdate(),modified_by = 1159
where enc_id in
('C24E6640-D2CC-45C6-8C74-74F6466FA262',
'762E6B26-AE4A-4FDB-A6FB-77B4782566C3',
'D7FBD152-F7AE-449C-A875-C85B5F6BB462')
What settings or whatever would cause this to take so much longer from the linked server?
Edit:
Note) Other queries from the linked server do not have this behavior. From the stored procedure where we have examined how long each query/update takes... this particular query is the culprit for the time eating. I thought it was to do specefically with this table. However as stated when a query window is opened directly onto that server the update takes no time at all.
2nd Edit:
Could it be to do with this linked server setting?
Collation Compatible
right now it is set to false? I also asked this question in a message below, but figured I should put it up here.

I am hoping someone can shed light on this odd behavior I am seeing running a simple UPDATE statement on a table in SQL Server 2000. I have 2 tables - call them Table1 and Table2 for now (among many) that need to have certain columns updated as part of a single transaction process. Each of the tables has many columns. I have purposely limited the target column for updating to only ONE of the columns in trying to isolate the issue. In one case the UPDATE runs fine against Table1... at runtime in code and as a manual query when run in QueryAnalyzer or in the Query window of SSManagementStudio - either way it works fine.
However, when I run the UPDATE statement against Table2 - at runtime I get rowsaffected = 0 which of course forces the code to throw an Exception (logically). When I take out the SQL stmt and run it manually in Query Analyzer, it runs BUT this is the output seen in the results pane...
(0 row(s) affected)
(1 row(s) affected)
How does on get 2 answers for one query like this...I have never seen such behavior and it is a real frustration ... makes no sense. There is only ONE row in the table that contains the key field passed in and it is the same key field value on the other table Table1 where the SQL returns only ONE message (the one you expect)
(1 row(s) affected)
If anyone has any ideas where to look next, I'd appreciate it.
Thanks

Hi SQL fans,I realized that I often encounter the same situation in a relationdatabase context, where I really don't know what to do. Here is anexample, where I have 2 tables as follow:__________________________________________ | PortfolioTitle|| Portfolio |+----------------------------------------++-----------------------------+ | tfolio_id (int)|| folio_id (int) |<<-PK----FK--| tfolio_idfolio (int)|| folio_name (varchar) | | tfolio_idtitle (int)|--FK----PK->>[ Titles]+-----------------------------+ | tfolio_weight(decimal(6,5)) |+-----------------------------------------+Note that I also have a "Titles" tables (hence the tfolio_idtitlelink).My problem is : When I update a portfolio, I must update all theassociated titles in it. That means that titles can be either removedfrom the portfolio (a folio does not support the title anymore), addedto it (a new title is supported by the folio) or simply updated (atitle stays in the portfolio, but has its weight changed)For example, if the portfolio #2 would contain :[ PortfolioTitle ]id | idFolio | idTitre | poids1 2 1 102 2 2 203 2 3 30and I must update the PortfolioTitle based on these values :idFolio | idTitre | poids2 2 202 3 352 4 40then I should1 ) remove the title #1 from the folio by deleting its entry in thePortfolioTitle table2 ) update the title #2 (weight from 30 to 35)3 ) add the title #4 to the folioFor now, the only way I've found to do this is delete all the entriesof the related folio (e.g.: DELETE TitrePortefeuille WHERE idFolio =2), and then insert new values for each entry based on the new givenvalues.Is there a way to better manage this by detecting which value has to beinserted/updated/deleted?And this applies to many situation :(If you need other examples, I can give you.thanks a lot!ibiza

If I have a table with 1 or more Nullable fields and I want to make sure that when an INSERT or UPDATE occurs and one or more of these fields are left to NULL either explicitly or implicitly is there I can set these to non-null values without interfering with the INSERT or UPDATE in as far as the other fields in the table?
EXAMPLE:
CREATE TABLE dbo.MYTABLE(
ID NUMERIC(18,0) IDENTITY(1,1) NOT NULL,
FirstName VARCHAR(50) NULL,
LastName VARCHAR(50) NULL,
[Code] ....
If an INSERT looks like any of the following what can I do to change the NULL being assigned to DateAdded to a real date, preferable the value of GetDate() at the time of the insert? I've heard of INSTEAD of Triggers but I'm not trying tto over rise the entire INSERT or update just the on (maybe 2) fields that are being left as null or explicitly set to null. The same would apply for any UPDATE where DateModified is not specified or explicitly set to NULL. I would want to change it so that DateModified is not null on any UPDATE.
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
VALUES('John','Smith',NULL)
INSERT INTO dbo.MYTABLE( FirstName, LastName)
VALUES('John','Smith')
INSERT INTO dbo.MYTABLE( FirstName, LastName, DateAdded)
SELECT FirstName, LastName, NULL
FROM MYOTHERTABLE

Hello,I am trying to update records in my database from excel data using vbaeditor within excel.In order to launch a query, I use SQL langage in ADO as follwing:------------------------------------------------------------Dim adoConn As ADODB.ConnectionDim adoRs As ADODB.RecordsetDim sConn As StringDim sSql As StringDim sOutput As StringsConn = "DSN=MS Access Database;" & _"DBQ=MyDatabasePath;" & _"DefaultDir=MyPathDirectory;" & _"DriverId=25;FIL=MS Access;MaxBufferSize=2048;PageTimeout=5;" &_"PWD=xxxxxx;UID=admin;"ID, A, B C.. are my table fieldssSql = "SELECT ID, `A`, B, `C being a date`, D, E, `F`, `H`, I, J,`K`, L" & _" FROM MyTblName" & _" WHERE (`A`='MyA')" & _" AND (`C`>{ts '" & Format(Date, "yyyy-mm-dd hh:mm:ss") & "'})"& _" ORDER BY `C` DESC"Set adoConn = New ADODB.ConnectionadoConn.Open sConnSet adoRs = New ADODB.RecordsetadoRs.Open Source:=sSql, _ActiveConnection:=adoConnadoRs.MoveFirstSheets("Sheet1").Range("a2").CopyFromRecordset adoRsSet adoRs = NothingSet adoConn = Nothing---------------------------------------------------------------Does Anyone know How I can use the UPDATE, DELETE INSERT SQL statementsin this environement? Copying SQL statements from access does not workas I would have to reference Access Object in my project which I do notwant if I can avoid. Ideally I would like to use only ADO system andSQL approach.Thank you very muchNono

It appears to update only the first qualifying row. The trace shows a row count of one when there are multiple qualifying rows in the table. This problem does not exist in JDBC 2000.

I'm having a strange problem that I can't figure out. I have an SQL stored procedure that updates a small database table. When testing the Stored Procedure from the Server Explorer, it works fine. However, when I run the C# code that's supposed to use it, the data doesn't get saved. The C# code seems to run correctly and the parameters that are passed to the SP seem to be okay. No exceptions are thrown.
The C# code:
SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["touristsConnectionString"].ConnectionString);
SqlCommand cmd = new SqlCommand("fort_SaveRedirectURL", conn);
cmd.CommandType = CommandType.StoredProcedure;
Label accomIdLabel = (Label)DetailsView1.FindControl("lblID");
int accomId = Convert.ToInt32(accomIdLabel.Text);
cmd.Parameters.Add("@accomId", SqlDbType.Int).Value = accomId;
cmd.Parameters.Add("@path", SqlDbType.VarChar, 250).Value = GeneratePath();
try
{
conn.Open();
cmd.ExecuteNonQuery();
}
catch(Exception ex)
{
throw ex;
}
finally
{
conn.Close();
}
The Stored Procedure:
ALTER PROCEDURE developers.fort_SaveRedirectURL
(
@accomId int,
@path varchar(250)
)
AS
DECLARE
@enabled bit,
@oldpath varchar(250)
/* Ensure that the accommodation has been enabled */
SELECT @enabled = enabled FROM Experimental_Accommodation
WHERE Experimental_Accommodation.id = @accomId
IF (@enabled = 1)
BEGIN
/* Now check if a path already exists */
SELECT @oldpath = oldpath FROM Experimental_Adpages_Redirect
WHERE Experimental_Adpages_Redirect.accom_id = @accomId
IF @oldpath IS NULL
BEGIN
/* If Path already exists then we should keep the existing URL */
/* Otherwise, we need to insert a new one */
INSERT INTO Experimental_Adpages_Redirect
(oldpath, accom_id)
VALUES (@path,@accomId)
END
END
RETURN

I'm new to this forum.
This 'problem' has occured many times, but I've always found a way around it.
I have pages with datagrids, in which a user can edit a certain fields and then update the tables with new data. Lets say when a user edit a Name field and a money field. If he/she left those two fields blank, the table is automatically updated with a <null> (for the name field) and a 0 (for the money field.) Both these columns were set up to allow Null values.
Anyone has an idea why they were updated that way? And is there like a standard on how the data types are updated if a field is left blank?
Thank you very much.
