I have a dynamic page that accepts a "type" query string. This type query string is the name of a table I want to display on the page in the GridView. Creating a different SqlDataSource/Strongly typed class for every type isn't possible because I need to make this flexible for future updates. So therefor I basically need to be able to Sort, Page, Edit and Delete with the Grid View without knowing the table name at compile-time.
Hello, Has anyone used/fiqured out how to set one of the properties below to a variable with a dynamic database. <asp:SqlDataSource ID="Sql_Imports" runat="server" selectcommand='EXEC <%# Session("CompanyDB") %>..IMPORT_S' ConnectionString=""></asp:SqlDataSource> You would have thought that Microsoft would have allowed catalog/database on this command. Thanks.
OK so I need to use a dynamic SQL statement in a SqlDataSource object because I need to pass in the column name. I'm having trouble accounting for the apostophes I have to interpret literals within the statement. This is connecting to an Oracle database. This is what I originally tried... <asp:SqlDataSource ID="SqlDataSourceMine" runat="server" ConnectionString="<%$ ConnectionStrings:My_Connection_String %>" ProviderName="<%$ ConnectionStrings:My_Connection_String.ProviderName %>" SelectCommand="SELECT m.YIE, :selecteditem, m.ENDTIME FROM MyMAP.MAP_M_SUM m WHERE (m.GROUPID LIKE 'YC%' AND m.GROUPID NOT LIKE 'YCX%' AND m.ENDTIME >= SYSDATE-14)"> <SelectParameters> <asp:ControlParameter Name="selecteditem" ControlID="itemlabel" PropertyName="Text" Type="String" /> </SelectParameters></asp:SqlDataSource> And the second column returned as :selecteditem for the column name and the value of itemlabel.text (what I wanted to be the column that was queried) as the value in each of the rows of that column. So I tried dynamic SQL to put the value of itemlabel.txt as the column to be queried, but I'm not sure how to get the query to read the literals. How can I accomplish this? <asp:SqlDataSource ID="SqlDataSourceMine" runat="server" ConnectionString="<%$ ConnectionStrings:My_Connection_String %>" ProviderName="<%$ ConnectionStrings:MY_Connection_String.ProviderName %>" SelectCommand="EXEC('SELECT m.YIE, '+selectedbin+', m.ENDTIME FROM MMAP.MAP_M_SUM m WHERE (m.GROUPID LIKE '+paramlike+' AND m.GROUPID NOT LIKE '+paramnotlike+' AND m.ENDTIME >= SYSDATE-14)')"> <SelectParameters> <asp:ControlParameter Name="selectedbin" ControlID="binlabel" PropertyName="Text" Type="String" /> <asp:ControlParameter Name="paramlike" ControlID="Label1" PropertyName="Text" Type="String" /> <asp:ControlParameter Name="paramnotlike" ControlID="Label2" PropertyName="Text" Type="String" /> </SelectParameters></asp:SqlDataSource> This errors to "illegal variable name" Can someone help me out please? Thanks a lot. -steve
I have a datasource on my ASP.NET 2.0 control I want to make dynamic. I have 6 different connection strings in my web.config file and want to change the connection with the selection in dropdownbox. Here is my VB code:Protected Sub GetDatabase(ByVal intDb As Integer) Select Case intDb

Do I need to reference the whole connection string or is there a way I can reference the "NAME" id in the web.config file for the connection string?
Good morning.I'm writing an application that allows users to generate Personal Leave requests and route them to their managers.I'm using the integrated Windows Authentication, so I'm able to get the user's username from HttpContext.Current.User.Identity.Name.How do I dynamically generate the SelectCommand? Right now, I do:Dim strQuery As String = "SELECT * FROM [tblPLRequest] WHERE employee = '" & strUsername & "'"to get the query I want, but when I set my SelectCommand to that, it thinks it's a stored procedure (and can't find it).Am I going about this in the completely wrong way?Thanks.
I have a GridView (that uses SqlDataSource1) and a Dropdownlist. Depending upon the value selected on the DropDownList I need to select different stored procedures for the gridview. The problem is that I can do it without taking SqlDataSource1 by using DataSet or DataTable. But, I need to Use SQLDataSource1 for easy way of Header SORTING. So, is there any way to change the SQLDatasource1.SELECT Command dynamically. So that, I can use different queries for the Single DataGrid. I have attached the sample code of the SqlDataSource1 I'm using. I need to change the Command i.e. SelectCommand="usp_reports_shortages" to "usp_reports_shortagesbyID" and "usp_reports_shortagesbyDate" depending on the value selected in the dropdownlist. So, is there any way to do this????<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:TESTDrivercommunication %>"
I am trying to implement an "advanced search" feature on my ASP.NET 2.0 web form. I have a GridView control and a SqlDataSource. The SqlDataSource control successfully retrieves data when the SelectCommand attribute is set in the aspx page. I need to make it so when a user clicks on a button, it can take a value from a text box and use it in the WHERE clause. I have tried setting the SelectCommand programmatically and then DataBinding but it never accepts the new SelectCommand. What can I do to fix this?
Hey, I have a search form with a selectbox. This selectbox contains the columnnames.I want when I put a text in a textbox and select a value in the selectbox and click submit that it search database.The Columnnames I put in a session. If you see I have put in the querystring as columnname @sescolumn which I have initialised as asp:sessionparameter.But it gives no results. When I put @sescolumn between [] like normal columnnames are it doesn't work also. Can someon put my on the right path?
<asp:SqlDataSource ID="Database_ecars" runat="server" ConnectionString="<%$ ConnectionStrings:connectionstring %>" SelectCommand="SELECT [AutoID], [Merk], [Kleur], [Type], [Autotype], [prijs], [Zitplaatsen], [Afbeelding1], [Afbeelding2], [Afbeelding3], [Afbeelding4] FROM [Auto] where @sescolumn like @seskeyword and [AutoID] not in (select [AutoID] from [verhuring] where [StartVerhuur] >= @sesdatefrom and [Eindeverhuur] <= @sesdatetill)" > <SelectParameters> <asp:SessionParameter Name="sesdatefrom" SessionField="datefrom" Type="Decimal" /> <asp:SessionParameter Name="sesdatetill" SessionField="datetill" Type="Decimal" /> <asp:SessionParameter Name="seskeyword" SessionField="keyword" Type="string" /> <asp:SessionParameter Name="sescolumn" SessionField="columnname" Type="string" /> </SelectParameters> </asp:SqlDataSource>
What is the C# code I use to do this? I'm guessing it should be fairly simple, as there is only one row selected. I just need to pull out a specific field from that row and then insert that value into a different SqlDataSource.
i am using visual web developer 2005 with SQL Express 2005 with VB as the code behindi have one database and three tables in itfor manipulating each table i am using separate SqlDataSource() is it sufficient to use one SqlDataSource() for manipulating all the three tables ? i am manipulating all the tables in the same page only please help me
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. http://forums.microsoft.com/msdn/showforum.aspx?forumid=80&siteid=1 http://forums.microsoft.com/msdn/showforum.aspx?forumid=80&siteid=1
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.
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 tried building an Inline TVF, as I assume this is how it would be used on the DB; however, I am receiving the following error on my code, I must be missing a step somewhere, as I've never done this before. I'm lost on how to implement this clr function on my db?
Error: Msg 156, Level 15, State 1, Procedure clrDynamicPivot, Line 18 Incorrect syntax near the keyword 'external'. CREATE FUNCTION clrDynamicPivot ( -- Add the parameters for the function here @query nvarchar(4000), @pivotColumn nvarchar(4000),
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

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
I am trying to create an ssis package with dynamic csv file as output. and out format contains query output.
sample file name:
Unique identifier + query output + systemdate();
The expression is looking like this.
@[User::FilePath] + @[User::FileName] + ".CSV"
-- 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!

hi all, in all my 2.0 learnings and books i keep coming across the page element <asp:sqldatasource>. I have always (in 1.1) used server side connections and adapters to bind my Sql datasets to any control needed. Now that im learning 2.0 im finding it difficult to understand using control on the page to bind my data. Can someone explain the benefits of using this data source? Ideally i would like to keep my data access layer separate from my presentation layer but i'd really like to understand why this method seems so popular. thanks in advance, mcm
Hi, I am new to ASP.NET 2.0 and I am trying to use VWB to bind my web site to a SQL Express edition. I used SQLDataSource to specify the .mdf file so I can connect to my tables but when I click on the advanced button to generate the Insert, Update, Delete SQL I find it grayed out and it cannot be clicked. I looked into several tutorials online and I couldn't find the problem, can anyone explain what I am missing or doing wrong? Any suggestion is very appreciated. Thanks

Hi, I want to know when to use an sqlDataSource object because I used to populate for example a listBox control in visual studio net 2003 from AQLK server database by using a connection object, command object, dataAdapter object and a DataSet object. I discovered if I use sqlDataSource object (using visual studio net 2005) ,all I need is to write the connection string and a Select statement as properties for that sqlDataSource, so why to use the above mentioned objects(connection,command,adapter,dataset) while I can access any database in sql server through the use of sqlDataSource? I appreciate if you can explain to me the difference and when to use an sqlDataSource thx
