How To Put Value In Control If There Is No Data In Table.
Feb 22, 2008
i am trying to get value from a table and put the vale in label control but i have null data in the table. if i have null data then i want the label to have " 1 " as the value.
this is my code. when i run this i get error. Operator '=' is not defined for type 'DBNull' and string "". Dim conn As SqlConnection = New SqlConnection(ConfigurationManager.ConnectionStrings("ConnectionString").ConnectionString)
Dim cmd As SqlCommand = New SqlCommand("SELECT MAX(PageHit) From BusinessLog WHERE (BusinessID=@BusID)", conn)cmd.Parameters.AddWithValue("@BusID", strBusID)
Inside my SQL 2005 database I have a SmallDateTime with the layout "mm/dd/yyyy hh:mm:ss AM/PM" and then on a selected date of a calendar control it returns the date with 12:00:00 AM which obviously doesn't match with my database's time.
So, I'm looking for a way to drop the time off completely (for the query purpose) the database date when running a select statement. I don't want to touch SQL table data by modifying it, I just want to be able to query sql table using calendar control. Does anyone now how to accomplish this? Thank you in advance. - Nietzky
Is it possible to Group data in a Matrix exactly similar to Table Control. For example, my table control would group data as follows:
Region Country City $ales
North America
USA
Chicago 4 MM
LA 10 MM
NYK 6 MM
Canada
Toronto 4 MM
while the matrix would display as:
North America USA Chicago 4MM
LA
NYK
Canada Toronto ...
Do you see the problem? The matrix is starting the subgroup at the same level as the parent group. How do I make a sub group start at the row below the parent group row in matrix just like in the table above?
Does anyone have an example of performing a source to destination data load with another SQL Select Statement controlling source statement? What I would like to do is split up a huge data move by performing a loop on the source and modifying the source select "where" clause using values from a control table. I understand how to modify the source statement by using an expression statement with variables. Now I'm trying to figure out how to loop through a control table to drive the source task.
Hi All, I am placing a Matrix inside the table control for grouping requirements,but when we export the report to the Excel, the contents inside the table cell are ignored. Is there any way to get the full report exported, as per the Requirement.Please help me with this issue.
Hello All,I have a SQLDataSource "sdsX" which has four records. There is a DataList "dlX" which is binded to this SQLDataSource "sdsX". Now I want that my datalist "dlX" take third record of "sdsX" as its first element. Is there any property which can be used.Thanks
I am trying to create a table that will list data for me. The problem that I have is that my data has been separated across multiple stored procedures. The way I want to display the items are as follows:
title1 title2 title3 title4 title5 title6 title7
item1 item2 item3a item4 item5 item6a item7
item3b item6b
item3c item6c
As you can see, items3 & 6 contain significantly more rows than the others. In order to prevent duplicating items1, 2, 4, 5, and 7, I had to split the statement up into 3 stored procedures; all three procedures take parameters, item 3 and 6 taking item1 as a parameter. How will I display data like that in a report? In the design view, I am only able to use 1 dataset, let alone link them up together.
If this cannot be done, is there a query that I can perform that will omit repeated items? Basically, it will look exactly like about. I thought it was the GROUP BY, but I was way off.
hi all, i wonder if could accomplish this problem in sql..
say i wanna total sum up some qty in table 1, and the sum up qty appear in table 2.. means everytime qty in table 1 change, it will sum up automatically total qty in tbl1 :-
table 1 id qty 1 5 2 5 2 5 1 5
table 2 id SumQty 1 10 2 10
note: table 2 will sum up automatically, isit possible to do this?
I have a table that display large amounts of text in some fields. The table only has two columns (Field Name and Field Data). If the Field data is too large to fit on the same page as the field above it, it pushes to the next page, and then starts printing at the top of that page (the next page down).
I tried setting the "Keep Together" property of the table = True, but this was of no use.
Has anyone found a way to work around this, and if so could you let me know what you had to do. It may just be a SQL Server default setting that cannot be changed. I just want to research all possibilities before reporting back to the users.
Hi, on my local SSRS (RDLC), I have a table which presents several items, however these are not sequential data from a table on my DB, are fields of only one row of a table on my DB. More specificly, I have a table with the fields issue1, description1, issue2, description2...until 6! I want to present those fields six times (the same times as they appear on the DB), however, I only want them to appear is the issuex (which is an integer) is greater than 0. So to guarantee that each field only appears one time, I do this:
=First(Fields!issue1.Value) to each table line
And what I want to do on each line is IIF(Fields!issue1.Value > 0,True,False) to make that line visible or not, however, if I apply this to a line it automatically applies it to the complete table, and if only one of this conditions returns false the complete table becomes invisible.
Is there anyway to make this work dynamically?!?Thanks a lot!

I have made a SQLDataSource control with the select command: SELECT COUNT(*) AS 'Antall' FROM Utgivelse WHERE (medieID = @medieID) I want to use the "Antall" result programmatically in C# code. I try the following statement: IDataReader MyReader;
MyReader = CType(SqlDataSource2.Select(DataSourceSelectArguments.Empty),IDataReader); but it doesnot work. Can somebody help me how to get the data from th control ? Tom
After selecting the CursorType, CursorLocation, LockType and Disconnected status of your Recordset (there are defaults). I bind my controls and that is it
Then I can Navigate, Add New, Delete, Refresh, Search and Save Changes to my recordsets without any other code. That is really it, no other code is needed.
I am trying to think of a way to read a control table, build the SQL statement for each line, and then execute them all, without using a cursor.
To make it simple... control table would look like this:
CREATE TABLE [dbo].[Control_Table]( [Server_Name] [varchar](50) NOT NULL, [Database_Name] [varchar](255) NOT NULL, CONSTRAINT [PK_Control_Table] PRIMARY KEY CLUSTERED
[Code] ....
So if we then load:
insert into zt_Planning_Models_Plant_Include_Control_Table values ('r2d2','planing1'), ('r2d2','planing7'), ('deathstar','planing3')
Then you would build a SQL script that would end up looking like the following (note all the columns are the same):
insert into master_models Select * from r2d2.planning1.dbo.models insert into master_models select * from r2d2.planning7.dbo.models insert into master_models Select * from deathstar.planning3.dbo.models

Is there a way to retrieve a returned value from a stored procedure w/out binding do a data presentationi control? I have the following sqldataprovider... <asp:SqlDataSource ID="SqlDataSource1" runat="server" SelectCommand="f_GetUser" ConnectionString="<%$ ConnectionStrings:MyServer %>" SelectCommandType="StoredProcedure"> <SelectParameters> <asp:formparameter name="username" formfield="txtusername" /> <asp:formparameter name="password" formfield="txtpassword" /> </SelectParameters> </asp:SqlDataSource> Do I have to make a gridview to get the value that is returned from this stored procedure? The SP only returns one value (a count of records) and I want to set it to a variable. Is there a way, similar to a recordset in ASP, that I can access that one value? here is my stored procedure... CREATE PROCEDURE f_GetUser @username varchar(50), @password varchar(50)
AS SELECT COUNT(*) AS numusers FROM f_Users WHERE username=@username AND password=@password I just want to retrieve "numusers" and use it in a conditional.... tia for your help

I just want to insert a record into a table using a SqlDataSource control. But I'm having a hard time finding examples that don't use data bound controlsI have this so far (I deleted the parts not related to the insert):<asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:UserPolls %>" InsertCommand="INSERT INTO [PollAnswers] ([PollId], [AnswerText], [AnswerCount]) VALUES (@PollId, @AnswerText, @AnswerCount)" <InsertParameters> <asp:Parameter Name="PollId" Type="Int32" /> <asp:Parameter Name="AnswerText" Type="String" /> <asp:Parameter Name="AnswerCount" Type="Int32" /> </InsertParameters> </asp:SqlDataSource> This is the data source for a gridview control I have on the page. I could set up an SqlDataSource for this alone if I need to, but i don't know if it would help. From what I could find, in the code behind I should haveSqlDataSource2.Insert()and SqlDataSource2 will grab the parameters and insert the record. The problem is I need to set the Pollid (from a session variable) and AnswerText (from a text box) at run time. Can I do this?Diane
Hi, i have a listbox with multiple selection enabled, the end user uses this listbox to select what data they want to view eg. they select "green" to view all the green cars, "red" to select all the red cars etc. i have the listbox as the control that is connected to the datasource (the sql used for it is select * from cars_table where color =@colorthis works fine when one item in the listbox is selected, but when multiples are selected it does not work what format does the =@color have to be when multiples are selected? i've tried "green, red" "green + red" etc. but cannot seem to get it workingdoes anybody have any working examples that i can take a look at? it seems to be a common action, yet i cannot seem to find any documentation on how to get it to workthanks in advance!
Let's say... the sqldatasource has 3 columns: TableKey(int), TableName(string) and StartDate(datetime) and i'm writing a method to return the data type based on the column name.. for example: GetDataType("StartDate") should return "datetime"...what should i do?
When creating a user control (ascx) and registering it in the webpage, an error occurred: "Login failed for user ''. The user is not associated with a trusted SQL Server connection." This error does not appear when creating data access normally, and I don't use username/password for the northwind database; any suggestions.
I have an ASP page which uses an SQL data source control, as shown below: <asp:SqlDataSource ID="mySQL" runat="server" ConnectionString="<%$ ConnectionStrings:mySQLConnectionString %>" SelectCommand="SELECT device FROM device_table WHERE (device_id IN (@devicelist))"> <SelectParameters> <asp:Parameter DefaultValue="" Name="devicelist" Type="String" /> </SelectParameters> </asp:SqlDataSource>The problem is getting the "IN" clause of the select statement to work via the ASP page with code behind in C#. If I test the query in the page designer when configuring the SQL control by inserting 'device-1','device-2','device-3' as the value for the "devicelist" parameter, everything works as expected. However, when that same value is written programmatically into the DefaultValue of the parameter, the resulting query contains no results (as if the string contents are invalid). If I alter my program to supply a single entry (with no commas) it seems to work as well. I suspect the comma (and possibly the single-quote) characters in my string when multiple entries are involved are causing the issue.Is there a proper technique for getting the requisite quote-delimited, comma-separated list into the SQL control command parameter correctly? Should I be using some sort of escape sequence for the single-quote and comma characters? Should I be using another "type" for the parameter; one that accepts an array of entries? I have not been able to find any examples or documentation that provides an answer.
In my report, I have a Matrix control placed next to a table. It renders properly and displays data aligned in two controls in Visual Studio Preview. However, when I deploy to production, it wraps the matrix control below the table, in fact puts the entire matrix control underneath the table. Why such strange behavior and not in the Preview of the report but only in Production? Any ideas how to fix this?

I currently have a LoginStatus and LoginName control on my asp.net 2.0 master page. When successfully logged in a message displays "You are logged in as" LoginName. Since I am using the user's e-mail address as the UserName the message will display as "You are logged in as johndoe@foo.com". What I want to do is have the message display as "You are logged in as " FirstName LastName. FirstName and LastName are two new fields that I added to the table, aspnet_Users. What I have done is to use the FormView control to display FirstName and LastName; however this always displays the first record in the aspnetdb database. Is there a cleaner way (than the FormView control) to display the requested data, using the currently logged in user? I have access to Microsoft Expression Web and Visual Studio 2005, but I prefer Expression Web. Thank you in advance
I have a DB with the folloing fields... ArticleID, ArticleTitle, PublishDate(DateTime Field), EndPublishDate(DateTime Field).... What I want to do is show in a list view only the articles where the date is on or after the PublishDate and before or on the EndPubishDate. I thought I could simply do something like this SELECT ArticleTitle, PublishDate, PublishEndDate, PublishedFROM UserArticlesWHERE (Published = @Published) AND (PublishDate >= @PublishDate) AND (PublishEndDate <= @PublishEndDate)
Well I can't... can someone explain how I can do this please... I understand the the PublishDate and EndPublsihDate need a variable... The info is in the DB I just don't know how to do what I need to.
What are the options to create a table of contents based on the report items in a List Control? Document Mapping works for online viewing. A table of content would make the report easier to read when it's printed.
