i have a case :
i'm using a select statement with SqlCommand and save the results in the SQLDataAdapter
and using the data table I post the result to the gridview and show it there....
my question is what should I do to append string to the SQL Command??
How can I append a string to the field value in the select list
SELECT Code + '-20' FROM tb.....
I want to the above to return 2000-20 for example.
How can I do this?

I have built an Advanced Search page which allows users to select which columns to return (via checkbox) and to enter search criteria for any of the selected columns (into textboxes). I build the SQL statement from the properties of the controls. Works great.
My problem is getting my gridview control to play nicely. At first I used a SqlDataReader and bound the gridview to it, thus giving me the ability to run new SQL statements through it (with different columns each time). Worked nicely. But, per Microsoft, sorting can only be done if the gridview is bound to a datasource control like the SqlDataSource. So I wrote the code to handle sorting. No big deal; worked nicely. But I could not adjust the column widths programmatically unless bound to a datasource control like the SqlDataSource. And could not figure out a work around.
So, I decided to use the SqlDataSource. Works great. Except, I cannot figure out how to run a new SELECT statement through the SQLDataSource and have the gridview respond accordingly. If I try to return anything other than the exact same columns defined declaratively in the html, it pukes. But I need to be able to return a new selection of columns each time. For example, first time through the user selects columns 1,2,3,4 – the gridview should show those 4 columns. The second time the user selects columns 2,5,7 – the gridview should those 3 columns (and ONLY those 3 columns). Plus support selection and sorting.
I am desperate on this. I've burned 2.5 days researching and testing. Does anyone have any suggestions?
Thanks,

Hello everyone,
I have a view, NAS_vPosition that has a coloumn vLogin_Acting and I want to use the user.identity.name to select the row from this table that matches.
So far i have tried:
SelectCommand = "Select * FROM NAS_vPosition WHERE vLogin_Acting = ' <%=User.Identity.Name %> ' "
with no success.
Any help is appreciated
Hi,
I was wondering if it is possible to reference a value in a previous row as a field in a normal select statement, for example:
SELECT a.user_id, a.name, b.user_id, b.name
FROM Users a
LEFT OUTER JOIN Users b
WHERE (b.user_id = a.user_id - 1)
Unfortunantly my user_id values are not in sequence so I get null entries using that code. Instead of doing something as basic as -1 is there another way to reference the previous row?
I have a GridView dispalying from a SQLServerDataSource that is using a SQL Select Union statement (like the following):
SELECT FirstName, LastNameFROM MasterUNION ALLSELECT FirstName, LastNameFROM CustomORDER BY LastName, FirstName
I am wondering how to create Update and Insert statements for this SQLServerDataSource since the select is actually driving from two different tables (Master and Custom). Any ideas if or how this can be done? Specifically, I want the Custom table to be editable, but not the Master table. Any examples or ideas would be very much appreciated!
Thanks,

I'm trying to add a 'change password' control to my site and seem to be having some issues. I have code that works if I statically define what user is displayed on the form, but I cant get it to detect the 'authenticated' user and show them the reset for for that ID.If I take the "+ myid" out of the select statement and just define the username statically the form works properly. Error:System.Data.SqlClient.SqlException: The column prefix
'System.Security.Principal' does not match with a table name or alias name used
in the query. Here's a piece of the code that is supposed to detect the current logged in user. However, it gives the error. (some of the code may be redundant but its not causing issues that I can tell) public void InitPage() { IPrincipal p = HttpContext.Current.User; String myid = HttpContext.Current.User.ToString(); SqlServer sqlServer = new SqlServer(Util.SqlConnectionString()); DataTable dt; SqlConnection cnn = new SqlConnection(ConfigurationManager.ConnectionStrings["myconnection"].ConnectionString); SqlDataAdapter cmd1 = new SqlDataAdapter("select * from USER WHERE USER_NAME = "+ myid, cnn); DataTable UIDtable = new DataTable(); cmd1.Fill(UIDtable); User_Id.Value = UIDtable.Rows[0]["ID"].ToString(); dt = sqlServer.USER_SELECT(Util.SiteURL(Request.QueryString["Pg"].ToString()), User_Id.Value);
I'm trying to run a SELECT statement to get two different values from a field that looks like this:
"Sample text [123], Sample text 2 [345]"
The two values I'm trying to grab has to be after the last comma. So in this case, I need to get
Value 1: 345
Value 2: Sample text 2
Is this possible to do? I can't create functions to accomplish this.
is there a way to have a select statement which compares a value is like ('%a%','%b%','%c%','%d%','%f%','%l%')
so :
select address
from customers
where address like ('%a%','%b%','%c%','%d%','%f%','%l%')
???
Hi,
I got a really simple question here. Say I have a table with
ID, Name
1, A1
2, A2
3, A3
....
10, A10
Now I want to combine the names into another table grouped by their ID (say 1-5, 6-10), so this new table has two names instead of 10:
A1 A2 A3 A4 A5
A6 A7 A8 A9 A10
Is there a function that allows me to 'combine' the names from a select statement?
Thanks in advance,

Hello, I'm needing to pass a variable length number of values to a select statement so I can populate a result list with items related to all the checkboxlist items that were selected by the user. for example, the user checks products x, y and z, then hits submit, and then they see a list of all the tests they need to run for each product. I found a UDF that parses a comma delimited string and puts the values into a table. I learned how to do this here: http://codebetter.com/blogs/darrell.norton/archive/2003/07/01/361.aspx I have a checkboxlist that I'm generating the string from, so the string could look like this: "1,3,4,5,7" etc.I added the function mentioned in the URL above to my database, and if I understand right, I should be able to pass the table it creates into the select statement like so:
WHERE (OrderStatus IN ((select value from dbo.fn_Split(@StatusList,','))) OR @StatusList IS NULL) but now I don't know how to assign the string value to the parameter, say to '@solution_id'.my current select statement which was generated by Visual Studio 2005 looks like this: SELECT [test], [owner], [date] FROM [test_table] WHERE ([solution_ID] = @solution_ID) ...but this only pulls results for the first item checked in the checkboxlist.Does anyone know how this is done? I'm sure it's simple, but I'm new to ASP .NET so any help would be greatly appreciated.
Hi all,I have created this simple Stored procedure. But it gives me wrong result when I pass a parameter to it. But if I hard
code it, it gives me the right result.
The I check if the field value of 'Email' is exactly equal to the parameter '@Email'.
The field 'Email' is varchar, and CID is integer.
CREATE PROCEDURE EmailExists @Email varcharASSELECT CIDFROM CustomersWHERE Customers.Email = @Emailreturn
Instead, if I check the value directly, it gives me correct answer. The the following code works fine when I typethe Email directly in the code.
CREATE PROCEDURE EmailExists @Email varcharASSELECT CIDFROM CustomersWHERE Customers.Email = 'tomyseba@yahoo.com'
return
Can anyone tell me the reason for it.
Thanking you in advance

In SQL 2000 DTS, I was able to append data from an ODBC source to a SQL 2000 destination table. The destination table was created by copying an attached source table in Access to a new table, then upsizing it to SQL. The character fields come over as varchar, and that seemed to be fine with the DTS job.
Now using the same source table and the same SQL destination, only in SQL 2005 with Integration Services instead of DTS, I get an error because the connection manager interprets the source text fields as Unicode and the destination fields are varchar.
I could script the table and change the text fields in the destination table to nvarchar, but this could have adverse affect on the application that uses the destination table. Is there a way to make the connection manager see the source text fields as varchar, or have the integration package allow the append even though the destination is varchar and the source is nvarchar?
Hi All,
When calling my SELECT statement, I would like to have Column name and Data type as the first record. Is this possible to do?
I would like to make a SP that would select all data from any table(with a header row) with just:
_sp_getData ' table_name'
I looked at sysobjects, and syscolumns tables, but was unable to put it all together. I have over 200+ tables, so creating variables for every column is very cumbersome.
Something like this:
select 0 AS SortCol ,
cast(min(case ordinal_position when 1 then column_name end) as varchar) as col1,
cast(min(case ordinal_position when 2 then column_name end) as varchar) as col2,
cast(min(case ordinal_position when 3 then column_name end) as varchar) as col3,
cast(min(case ordinal_position when 4 then column_name end) as varchar) as col4,
cast(min(case ordinal_position when 5 then column_name end) as varchar) as col5,
cast(min(case ordinal_position when 6 then column_name end) as varchar) as col6,
cast(min(case ordinal_position when 7 then column_name end) as varchar) as col7,
cast(min(case ordinal_position when 8 then column_name end) as varchar) as col8,
cast(min(case ordinal_position when 9 then column_name end) as varchar) as col9
from information_schema.columns where table_name = 'authors'
union all
select 1 , au_id, au_lname, au_fname, phone, address, city, state, zip,
cast(contract as varchar)
from authors
Is not an option.
Thank you very much in advance,

I have the below select command in my gridview that uses a library name.table approach in the sql. I created a label on the page and want to pass the label in where i have the libarary1 text in the select statement. This will allow me to swap out the production library with my development library when im working on the site (thru the use of a site variable)
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:as400con %>"ProviderName="<%$ ConnectionStrings:as400con.ProviderName %>" SelectCommand="SELECT * from library1.table WHERE COMPANY = ? and ack = ? and HORZN_DATE <= ?">

How would I insert a label.text value into the select statement replacing the library1 ? I tried to use the asp:controlparameter adding the text and placing a ? mark in place of the library1 but it failed.
Thanks for any help you can lend on this,

Hi,
I develop a application for mobile devices using C# and Visual Studio 2005 with .NET Compact Framework 2.0. My application is very sample: have a master form where user browse the records in a grid and a detail form for insert and alter the record's.
The application runs fine when the database is empty. I have a problem with combobox bounded components when the sequence above is executed:
1. After append a some of records end the application;
2. Run the application again (the records was in database);
3. Append new record;
4. Cancel the operation;
The first record of the group is changed without user confirmation. The value of each field is changed for the first value of combobox bounded with then.
Why?
The code below cause the problem:
TableBindingSource.AddNew();
DetailEditViewDialog detailEditViewDialog = DetailEditViewDialog.Instance(TableBindingSource));
detailEditViewDialog.Text = "[New]";
detailEditViewDialog.comboBoxCars.SelectedIndex = -1;
detailEditViewDialog.comboBoxPumps.SelectedIndex = -1;
detailEditViewDialog.comboBoxLines.SelectedIndex = -1;
detailEditViewDialog.ShowDialog();
Somebody can help me?

I have a form that has 4 fields to fill in. I have a button that can add these fields to a sql database. I also want to put a button next to the "add" button so you can fill out the same fields and search for those values. Here's what i have so far. I want to select based on the fields, but i'm having trouble with the syntax of the parameters. I also want to add something, so if nothing is filled out in one of those boxes, it retuns back all records for the default value.
string strConnection = ConfigurationManager.ConnectionStrings["TimeAccountingConnectionString"].ConnectionString;
SqlConnection myConnection = new SqlConnection(strConnection);

I am using a sqlDataSource to read my query and to put the rows into a gridview. Now I want to read just a couple of rows from my query based on a maximum number, also defined in the table. I have absolutely no idea how to do that..for example: I want to view only the 10 most recent subsciptions into my gridview. The subscriptions are stored into tabel Subscriptions which has values id, userid,date. Table Event has a parameter "maximum subscriptions" (which is 10 in my example) I hope it is clear enough?Thank you in advance!BlueiVeinz

Hi there,I am not sure how many of you have experienced this problem before but here is how to replicate it: Add a GridView, SqlDataSource and Button to a new projectSet the DataSourceID to the SqlDataSource objectSet AllowPaging to True on the GridViewWithin the Button1_Click sub, change the SqlDataSource.SelectCommand to a new Query e.g SELECT * FROM table WHERE ID > 1Run the project Click on another page, i.e. "3" on the GridView SqlDataSource.SelectCommand is now blank(!), thus Gridview displays nothing. Has anyone else found a solution to this annoying issue? Any help is appreciated.Regards

I have a report with a multi-value parameter that gets its values (value and label fields) from a dataset that is built at runtime (from vbscript code that returns a string).
When I press 'preview' all works fine.
When I add another multi-value parameter that (like the first parameter) gets its value from a dataset that is built at runtime (from vbscript code that returns a string) and press 'preview', I get a strange behavior:
The second parameter is disabled until I choose an option for the first parameter.
I do not pass value from the first parameter to the second and the two variables have 'Null' in the default values and 'from query' in the available values.
Why does the second parameter is disabled and how can I avoid it?
Thanks in advance.
I am working with a stored procedure that needs to roll up a week number column once a week - columns are numbered 1-10, 1 being this week, 2 being last week and so forth
Once a week the 10th column is deleted, the 9th becomes 10, the 8th becomes the 9th and so forth and the 1st is calculated the week numbers are getting all screwed up - and we think it's because one statement starts before the one before it completes the statements go like this:
delete theTable where week_num=10;
update theTable set weeknum=10 where weeknum=9;
update theTable set weeknum=9 where weeknum=8;
and so forth
is that the reason? is there any way not to start one statement until the one before it finishes?

If I have a sqldatasource on the page, is it run if it is not bound to a data object like a gridview?
Seems like if i want to access the data (like set a label text) from the sqldatasource I have to use code to first create a dataview then pick throught it. This seems like I'm running it twice. I'm new at .net so I dont know how to tell.
I don't want to write data select code programatically when I can just through an SDS on the page, but wondered it it ran just because it's on the page.

Hi, I am seeking a hopefully easy solution to spit back an error message when a user receives no results from a SQL server db with no results. My code looks like this What is in bold is the relevant subroutine for this problem I'm having. Partial Class collegedb_Default Inherits System.Web.UI.Page Protected Sub submit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submit.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] WHERE [name] like '%" & textbox1.Text & "%'" SqlDataSource1.DataBind() If (SqlDataSource1 = System.DBNull) Then no_match.Text = "Your search returned no results, try looking manually." End If End Sub Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End Sub Protected Sub reset_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles reset.Click SqlDataSource1.SelectCommand = "SELECT * FROM [college_db] ORDER BY [name]" SqlDataSource1.DataBind() End SubEnd Class I'm probably doing this completely wrong, I'm a .net newb. Any help would be appreciated. Basically I have GridView spitting out info from a db upon Page Load, but i also have a search bar above that. The search function works, but when it returns nothing, I want an error message to be displayed. I have a label setup called "no_match" but I'm getting compiler errors. Also, next to the submit button, I also have another button (Protected sub reset) that I was hoping to be able to return all results back on the page, similar to if a user is just loading the page fresh. I'd think that my logic would be OK, by just repeating the source code from page_load, but that doens't work.The button just does nothing. One final question, unrelated. After I set this default.aspx page up, sorting by number on the bottom of gridview, ie. 1,2,3,4, etc, worked fine. But now that paging feature, as long with the sorting headers, don't work! I do notice on the status bar in the browser, that I receive an error that says, "error on page...and it referers to javascript:_doPostBack('GridView1, etc etc)...I have no clue why this happened. Any help would be appreciated, thanks!
