Dynamically Adding New Parameters To SQLDataSource
Dec 28, 2007
CancelSelectOnNullParameterHi,
Suppose I have a SQLDataSource with a
SelectCommand="SELECT * FROM STOCKS WHERE USER=@USER ORDER BY STOCK_NAME"
and @USER is set as a session parameter. No problem till this part, but in some postbacks, I wish to add a new WHERE criteria to my SQL, so I do:DSSQL.SelectParameters.Add("@STOCK_NAME", "ABC123");
DSSQL.SelectCommand = DSgvStoklar.SelectCommand.Replace(" ORDER BY ", " AND STOCK_NAME LIKE @STOCK_NAME+'%' ORDER BY ");
gridViewDS.DataBind();
and wish that my SelectCommand is modified and a new parameter is added.
The SQL is modified, however -I guess- new parameter is not added, so I get "Must declare the scalar variable "@STOCK_NAME" error.
How can I solve, any ideas?

Hello all,
Ok, I finally got my SqlDataSource working with Oracle once I found out what Oracle was looking for. My next hurdle is to try and set the Update Command and Parameters dynamically from a variable or radiobutton list. What I'm trying to accomplish is creating a hardware database for our computers by querying WMI and sending the info to textboxes for insertion and updating. I got that part all working nicely. Now I want to send the Computer name info to a different table column depending on if it is a laptop or desktop. I have been tossing around 2 ideas. A radiobutton list to select what it is and change the SQL parameters or do it by computer name since we have a unique identifier as the first letter ("W" for workstation, "L" for Laptop). I'm not sure what would be easiest but I'm still stuck on how this can be done. I posted this same question in here a few days ago, but I didn't have my SqlDataSources setup like I do now, I was using Dreamweaver 8, it is now ported to VS 2005. Below is my code, in bold is what I think needs to be changed dynamically, basically i need to change DESKTOP to LAPTOP...Thanks for all the help I've gotten from this forum already, I'm very new to ASP.NET and I couldn't do this without all the help. Thanks again!
<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:CAT %>"ProviderName="<%$ ConnectionStrings:CAT.ProviderName %>" SelectCommand='SELECT * FROM "COMPUTER"' UpdateCommand="UPDATE COMPUTER SET DESKTOP = :DESKTOP, TECH = :TECH, SERVICE_TAG = :SERVICE_TAG WHERE USERNAME=:USERNAME">
<UpdateParameters>
<asp:ControlParameter Name="USERNAME" ControlId="txtUserName" PropertyName="Text"/>
<asp:ControlParameter Name="SERVICE_TAG" ControlId="txtServiceTag" PropertyName="Text"/>
<asp:ControlParameter Name="TECH" ControlId="txtTech" PropertyName="Text"/>
<asp:ControlParameter Name="DESKTOP" ControlId="txtComputerName" PropertyName="Text"/>
</UpdateParameters>
</asp:SqlDataSource>

I have several Sql Tables, each containing more than 100 fields, on which I need to perform display operation through GridView, Insert and Update through an array of dynamically created and databound TextBoxes.
I would like to use a single page to manage all Sql Tables on the basis of the name of the specific one invoked by the user.
In order to achieve that, I need to dynamically configure the SqlDataSource Web Control present on the page for each Sql Table. In particular I need to generate at runtime the InsertCommand and the UpdateCommand.
On how to do it I have no idea.

Can you dynamically set the name of the table in the SelectCommand section of the SqlDataSource? (If it is relevant, I code in C#)
For example,
<asp:SqlDataSource runat="server" ID="SqlDataSource1" ConnectionString="<%$ ConnectionStrings:Test-MySQL %>" ProviderName="<%$ ConnectionStrings:Test-MySQL.ProviderName %>" SelectCommand="SELECT * FROM TestTable">
I would like to replace 'TestTable' with the name of a table that is extracted from a string array in the code-behind.
Appreciatively,Peter

Hi all
I have a cms-page where i want to display various entry-categories like news etc....I want to define which kind of entries should be shown by a parameter in the URL (e.g. cms.aspx?category=news). So far everything is OK.
To display the entries actually I'm using the following SqlDataSource:
<asp:SqlDataSource ID="SqlDataSourceCMS" runat="server" ConnectionString="......."SelectCommand="SELECT * FROM [cms] where category = news"></asp:SqlDataSource>
What i need, is to set the category which i want to show dinamically, like with a variable.
Does anybody know how i can set something like a variable in the SelectCommand property of the SqlDataSource?

Hi,
I have a requirement to load tables in the database from files on a shared server (lets say 50 tables from 50 files). I do not want to hardocde the file path anywhere in the package since this would mean changing 50 packages everytime the path changes (say when moving to to a diff server).
In SQL Server 2000, I used a .ini file to pass the path and used a Dynamic properties task to set run time variables. That way, evertime the path changes, I only had to change 1 ini file and all packages picked up the new path from it. How do I do this in SQL Server 2005 ?
Appreciate any assistance / suggestion in this regard.
Thanks,
Bhaskar

I set up a stored procedure. My stored procedure has 8 variables declared at the beginning like this:
===========================
declare@IncurredDateStartsmalldatetime
,@IncurredDateEndsmalldatetime
,@PaidDateStart_CUsmalldatetime
,@PaidDateEnd_CUsmalldatetime
,@PaidDateStartsmalldatetime
,@PaidDateEndsmalldatetime
[Code] ....
All of these dates are based on the update of our data warehouse. This stored procedure runs a 5 step process and produces data for 8 - 10 monthly reports.
I was wondering if these variables can be updated dynamically and if they can how it is done.

SQL 2012 SSIS package.I have a package connection that has the initialcatalog set in the connection string/properties page. This package connection also has an expression defined to set the initial catalog at runtime according to a passed in parameter. It works fine.
I am trying to create a second package in this same manner, but the connection does not seem to want to keep both the hardcoded initialcatalog and the expression to set it dynamically.
I can hardcode the initcatalog just fine, when when I add the expression to set it dynamically later, it clears out the initialcatalog I added.
What am I missing, why was I able to do this in the other package? I compared as much as I can think of between the two packages, all seems similar.

Hi all
I hope someone can help me on this issue:
I am designing dynamical reports, that are abel to run in four different languages - so far everything works just fine for me (I select my headers and labels from a database). Only problem is the prompt text for report parameters. How can I set this text dynamically?
E.g. I have a parameter where the user selects a storage - this prompt should be "Storage: " in the English report and "Lager: " in the Danish report. I have absolutely no idea how to fix this.
I am greatful for any help.

I want to turn this SQL into a stored proc; there are currently about 8 parameters that I want to pass into it. The field value for each will be either NULL or a positive integer, and the paramater will be passed in as an integer.
If the passed parameter value is a positive integer then it should return all records where the corresponding field value matches that integer. If the passed parameter is 0, it should return all rows regardless of whether the field value is an integer or NULL.
And I can't for the life of me figure out how to do it. Do I need an IF statement in there or something?

I have three databases which have the identical data structure. When the user runs a report, he has to select a database.
For example, my report query would look like:
Select * from <theDatabase>.dbo.MyTable
How could I assign the value of <theDatabase> at run time depending on what the user selects from the list?
In my datasource, I have only specified the server name and no value for initial catalog.

Is
it possible to specify different parameters for the
select/update/delete stored procedures used by a sqldatasource? When I
'configure the datasource' it lists the different stored procedures for
each command, but when it comes to specifying the parameters it only
lets me do so for the select command. Is there another way to do this
for the other commands?
I have tried doing it manually in the aspx file (using the
DeleteParemeters etc), but I don't know how to reference a specific
cell in the selected row of the gridview for the controlparameter). Any
thoughts?

Hello I need help withsetting parameters for SqlDataSource
I have a simple program. I want display date from database on MS SQLSERVER from the table USERS only for current sing on user select by his login.
I save into this variable login current user: string @LOGIN = Context.User.Identity.Name;
I have already done with this way without SqlDataSource:
string login = Context.User.Identity.Name;
SqlConnection conn1 = new SqlConnection("server=CR\SQLEXPRESS;database=myData;integrated security=SSPI");
conn1.Open();
SqlCommand cmd1 = new SqlCommand(" SELECT IN_OUT.TIME_START, IN_OUT.TIME_END, FROM IN_OUT INNER JOIN USER ON USER.USER_ID=IN_OUT.RC_USER_ID where USER.LOGIN=@LOGIN", conn1);
cmd1.Parameters.Add("@LOGIN", SqlDbType.NVarChar, 50);
cmd1.Parameters["@LOGIN"].Value = login;
1.Parameters.Add("@LOGIN", SqlDbType.NVarChar, 50);
cmd1.Parameters["@LOGIN"].Value = login;
Now I don't know how to do with SqlDataSource, what I have to set in SqlDataSource1 yet
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString %>"
ProviderName="<%$ ConnectionStrings:myConnectionString.ProviderName %>" SelectCommand="SELECT IN_OUT.TIME_START, IN_OUT.TIME_END, FROM IN_OUT INNER JOIN USER ON USER.USER_ID=IN_OUT.RC_USER_ID where USER.LOGIN=@LOGIN">

I need to do some select & update from VB code behind a web page. Using VS2005, ASP.NET.
To me, the most logical approach would be to use a SqlDataSource. I can select the connection string, predefine select, insert and update queries and call the select(), and other commands from this control.
I need to use parameters in the queries but I cannot connect parameters straight to controls, I need to do it from VB. But nowhere can I find how to set the parameter values from code. I can find all kind of examples from VS2003 or using SqlCommand, but it should be possible from this control as well, but the help documentation is very poor in this respect.
Please provide me with some example.
Kind regards

I am creating simple report in ssrs and pass one parameter only. It will work perfectly (here user enter the parameter value). but i need that i should select the value in drop down box. i had tried many time and did different ways but I am unable to do it.
First i gave the parameter in my sql query in Data set (like WHERE COUNTRY = @COUNTRY) and i checked the Parameters tab in the data set. Here by default comes the Parameter Name: COUNTRY and Parameter value: [@COUNTRY].
Next i select COUNTRY Parameter in the Report Data Pane. and go to properties Here in General Tab: Name COUNTRY Prompt: COUNTRY, Select Get values from query in available values Tab (and also i tried with Select Get values from query in Default Value Tab) and Select Data set: Data Set1, Value field: COUNTRY and Label Field COUNTRY. And Click Ok
And tried to preview the report, it throwing below error
"An error Occured during local report processing. The definition of the report is invalid. The Report Parameter 'COUNTRY' has a DefaultValue or a ValidValue that depends on the report parameter "COUNTRY". Forward dependencies are not valid.
How can I achieve dropdown list.What i missed? Even i unable to do it Multi valued parameters and Cascading parameters.

Hello!
I am pulling my hair out over this latest problem. I'm trying to do a simple SQL SELECT statement by taking values from textboxes and inserting them into the WHERE part of the statement. I'm using MySQL and have to use ? prefix for all inserts, that I have working by the way. Now for some reason I cannot get the values from the text boxes to replace the prefixes! Here is my code:
private void submitLogin(object source, EventArgs e) {
if (isPassword(password.Text.ToString()) && isEmail(username.Text.ToString()))
{
ValidateCustomer.SelectParameters["c_email"].DefaultValue = "fish";
ValidateCustomer.SelectParameters["c_password"].DefaultValue = "cakes";
test_label.Text = ValidateCustomer.SelectCommand.ToString();
}
else {
test_label.Text = "Username or Password Incorrect";
}
}
<asp:SqlDataSource runat="server"
ID="ValidateCustomer"
ProviderName="System.Data.Odbc"
ConnectionString ="<%$ connectionStrings:MySQLDatabase %>"
SelectCommand ="SELECT * FROM customer_details WHERE (Customer_Email = ? AND Customer_Password = ?)">
<selectparameters>
<asp:parameter name="c_email" type="String" />
<asp:parameter name="c_password" type="String" />
</selectparameters>
</asp:SqlDataSource>
I have omitted obvious code. The test label, when updated, shows the SQL statement but with the ?. I also use controlparameters that took the values directly from the textboxes but again this did not work. I'm really stuck with this one. Your help is much needed!
Cheers
Dan
