I have a list box populated by a SqlDataSource with a basic statement of Select name where location = @location. Location is bound to a dropdownlist control. I want to have a checkbox for the Location dropdownlist and a checkbox for another dropdownlist (for the alphabet) that will select only those people with a last name of the letter selected. Changing the checkbox would change the sql statement. OK so there are two questions here: 1. How can I write a sql statement that would select only people whos last name begins with a certain letter. Would it use some sort of convert function to a string with only 1 letter? 2. How can I programatically change the sqlDataSource's 'select' statement. I need to switch between sorting by location and sorting by alphabetical last name. All of my previous experience has had me configuring the datasource in the asp.net code.

I have multiple SqlDataSources on a page. I only want them to execute the select query when the user performs a certain action. Is this possible? Or do they all execute as soon as the page is loaded?
Hello all, I have been working with a DetailsView control for the past week and it is a great control, but also lacks on some departments. Anyhow I need to know what the best approach for this scenerio would be?

My question is how will I be able to return the retval? Will I need to do it within the code behind of the SqlDataSource Updated Event? Thanks!

Hi you all, In abc.aspx, I use a GridView and a SqlDataSource with a SelectCommand. The GridView's DataSourceID is the SqlDataSource. In abc.aspx.cs, I would like to use an IF statement in which if a criterion is not satistied then I will use the SqlDataSource with another SelectCommand string. Unfortunately, I have yet to know how to write code lines in order to do that with the SqlDataSource. Plz help me out!
Is there a way to retreive the SQL Statement with the values from the parameters merged together? I know how to retreive the SQL Select Statement and the parameters separately but I need to retreive the final SQL. For example: SELECT name FROM employee WHERE id = @id I would like to retreive from SQLDataSource SELECT name FROM employee WHERE id = 1

I have a stored procedure with a SELECT statement, that retrieves 1 row. SELECT name FROM tblNames WHERE nameID = "1" I want all the NULL values in that row to be change in some default values. How do I do this?
I have consistent column names that load into a grid view. I now need to change the names in the grid view programatically. I was originally trying to get cute with SQL to do this, but I've been told my below solution will not work and I'm better off to do this in the presentation layer. If this is true, remember I'm still wet behind the ears here...how do I do this in vs2005? Here's my post to the SQL devs to give you an idea what I'm trying to do. I have a query that grabs fields from a denormalized table. The result is column names Week1, Week2, Week3....Week26. Users want to see the actual date instead of Week#. So I have a table (lkpdatecaptions ) that contains the fields "fldfieldno" and "Fldcaption". fldfieldno Fldcaption----------- --------------11 9/07/200712 9/14/200713 9/21/2007So fieldno 11 represent week1 and so on. So my hope is to update the alias with a query like: Select fldcaption from forecast.tlkpdatecaptionswhere fldfieldno = 11That quey returns the value of 9/7/2007 and is the value I need to represent the coumn alias name.My current query looks like this:SELECT SUM(forecast.tblforecastdenormalized.fldwk01) AS WEEK1,So can I do something like the following?SELECT SUM(forecast.tblforecastdenormalized.fldwk01) AS (Select forecast.tlkpdatecaptions.fldcaption from forecast.tlkpdatecaptions where fldfieldno = 11), ...
Wanted to enquire how this is done. Tried doing it in the setUsageType method I have overwritten but only allows description to be changed. Basically need to change "Name".
Best option would be to change it instantly when a user selects a column from the inputs in the custom component, ie. it changes the Output Alias to a desired value. (Input tab in advanced editor)
All this is being done in a custom component which I would like to be synchronous, can achieve a similar result asynchronously.
Hi, I've written a SELECT statement that returns columns dependant on a bitwise parameter @Populate.SELECTCASE WHEN (1 & @Populate) = 1 THEN [Column1] ELSE Null END AS [Column1],CASE WHEN (2 & @Populate) = 2 THEN [Column2] ELSE Null END AS [Column2],CASE WHEN (4 & @Populate) = 4 THEN [Column3] ELSE Null END AS [Column3],CASE WHEN (8 & @Populate) = 8 THEN [Column4] ELSE Null END AS [Column4],etcIs this the most efficient way to acheive this since I am only seeing a small performance gain. It still returns all columns but depending on @Populate will leave some columns with Null values.Any help much appreciated, thanks.
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.
Hi, say I have two Sqldatasources objects:SqlDataSource1 and SqlDataSource2.... Does anybody know how can I alter programmatically these two sqldatasources in a gridview? Thanks!!!

I have a sqldatasource, and on the selectcommand I'm trying to use a case statement with a subselect. The case statement works fine without the subselect, but I'm trouble getting it to work with the case statement. Could you help me with the syntax? ThanksSelectCommand=" SELECT DISTINCT RecipeID, Title FROM [Recipes] WHERE (CASE WHEN @Type='Appetizer' THEN Appetizer WHEN @Type='Pies' THEN (Select Distinct RecipeID, Title From Recipes WHERE Title like '%Pie%') WHEN @Type='Beverages' THEN Beverage WHEN @Type='Dessert' THEN Dessert WHEN @Type='Kids' THEN Kids WHEN @Type='Side' THEN Side WHEN @Type='Soup' THEN Salad WHEN @Type='Main' THEN Main WHEN @Type='Breakfast' THEN Breakfast END) = 1"
I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian
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.
hiI need to write a stored procedure that takes input parameters,andaccording to these parameters the retrieved fields in a selectstatement are chosen.what i need to know is how to make the fields of the select statementconditional,taking in consideration that it is more than one fieldaddedfor exampleSQLStmt="select"if param1 thenSQLStmt=SQLStmt+ field1end ifif param2 thenSQLStmt=SQLStmt+ field2end if
Code Block SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02' FROM myTables WHERE Conditions are true ORDER BY Field01
The results are just as I need:
Field01 Field02
------------- ----------------------
192473 8461760
192474 22810
Because other reasons. I need to modify that query to:
Code Block SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02' INTO AuxiliaryTable FROM myTables WHERE Conditions are true ORDER BY Field01 SELECT DISTINCT [Field02] FROM AuxTable The the results are:
Field02
----------------------
22810 8461760
And what I need is (without showing any other field):
Field02

8461760 22810
Is there any good suggestion? Thanks in advance for any help, Aldo.

Hi, I need to UPDATE the IP Address of a newly created user into a table (the value is currently set to default - " Not Available"), and I really dont know the syntax required to do this. So far I've derived all the variables needed using the following code: protected void ContinueButton_Click(object sender, EventArgs e) { //Get the ip address and put it into the customer table - (the instance of this user now exists) MembershipUser _membershipUser = Membership.GetUser(); Guid UserId = (Guid)_membershipUser.ProviderUserKey;<--------------------------------------------------------------I can see the UserId here if I pause the prog SqlDataSource customerDataSource = new SqlDataSource(); customerDataSource.ConnectionString = ConfigurationManager.ConnectionStrings["ConnectionString"].ToString(); customerDataSource.UpdateParameters.Add("IPAddress", Request.UserHostAddress.ToString());<---------------------------------------I can see the IPAddress here customerDataSource.UpdateCommandType = SqlDataSourceCommandType.Text; what next I've not got a clue as to what to write next. There is a try / catch statement after this using : rowsAffected = customerDataSource.Update(); which remains at 0 no matter what I try. Any help greatly appreciated.
I would like to use the value returned from my SqlDataSource SELECT method, in the INSERT method for the same SqlDataSource. Any ideas how this is done?
(Newbie). I'm trying to: 1) check if the SELECT command has returned any records, and 2) put a msg box on the screen if there are no records returned from the SELECT query. The type of code I'm heading towards is: (but it's wrong). Thank you in advance for your C# code suggestion. protected void SqlDataSource1_Selected(object sender, SqlDataSourceStatusEventArgs e) {if (SqlDataSource1.SelectParameters.Contains is "") then MessageBox.show ("There are no records available") ; }
I'm sure that is really simple, but how do I pass a parameter with multiple value to a SQLdatasource? ex: SELECT field1 from tblTableA where idTableA IN ( @Param1) Let's say I want to pass 1,2,3,4 as Param1 (SELECT field1 from tblTableA where idTableA IN ( 1,2,3,4)) How I am supposed tu use the .SelectParameters.Add() to pass a list of integers instead of a single value?? Thanks in advance.
