Print Out The Exact Update Statement That Occurs In A SqlDataSource?
Jun 15, 2010
Using vb.net/asp.net 2005.
I have a gridview that is using a SQLdataSource with an update statement and I am able to print out the update statement listed in the SQLDataSource by doing this:
[Code]....
but for some reason the record is not being updated so I want to know how do I print out the entire Update statement, including the value of the EmailAddressID to make certain that the update statement is being set correctly?
I can test the update statement above manually, taking the EmailAddressID for that record and then run the update statement manually using SQL Server Mgmt then it updates the record correctly so I know the update statement set in the SQLDataSource is ok. However I still want to print out the update statement that is supposed to be executed in the vb code, how to do this?
I see there is an event called "SqlDataSource1_Updating",
is it possible to print out the actual update statement there?
Just to be clear in the asp.net page I want to do something to print out the actual full update statement, ex:
<SQL>
UPDATE [EmailTable] SET [EmailAddress] = @EmailAddress WHERE [EmailAddressID] = 22
</SQL>
if there is anyway that I could duplicate controls in a asp.net pages. So for example, currently for one of my pages, I have a panel at the top of the page with alot of controls in them ( eg next/previous buttons, labels, trees, etc). However I wanted to add the exact duplicate of this panel on the bottom of the page aswell, with exact functionality.
I dragged and dropped a sqldatasource and want to do an insert statement, taking the new values from a textbox. I did this already however when i do my insert statement eg. INSERT INTO Development_Programme(MHID) VALUES (@m) HOWEVER when to select the insert parameters the 'Next' button and the 'Finish' button is shaded off, I added a Select statement and the 'Next' was unshaded HOWEVER the screen to select the insert parameters is not appearing it goes straight to the Test Query.
I was wondering how I could use user.identity in a where statement in sqldatasource to return results for a user profile. I already have a table that stores the username. Just need to return it's results.
I have a single column returning SQL data source and I want to use the data for a simple if statement, but for the live of me I can't figure out how to do it. *oh for the old days, I wrote the same thing in simple asp in about 45 seconds*
[code]....
For the life of me I can't figure out how to get that data into a variable or any way to access it. I know its probably simple. I have tried functions, etc off the net but everything I try results in another error.
I'd like to print out the select statement for a SqlDataSource to see exactly what is being issued to the database. I added an OnSelecting event and the code shown below. The problem is that it's printing the variables in the select statement rather than the values assigned to those variables. How do I print out the "resolved" output so that I can see the values being passed to the database.
I am new to asp.net, so this might be a basic question. But I am struggling on this for more time... I have loaded a COM object in Server script using code behind (C#) and that COM object will trigger events in some random interval. I need to update the client page whenever I receive an event from the COM object from server side (code behind).My question is, Is there a way to make the client page do postback from the code behind(C#)? ie., The client page needs to be updated whenever an event occurs in the server. Is that possible? The com event does not trigger a postback since it only occurs in the server and not in the client.
i have a webform which has got required field validators. when the user doesnt enter values and clicks submit button it should not cause postback. i have set CausesValidation="True" on the submit button.hen the user clicks submit button without entering values, validation occurs( red * marks are shown) but the postback also occurs.
using vb.net/asp.net 2005 and SQL Server 2005.I had similar issue yesterday: I created a unique index on a table to prevent duplicates when user tries to edit existing records in a gridview.This works fine and I am seeing the "cannot insert duplicate key row message...." however I need to catch the exception because I do not want to display the table and column names.I have this set up but its not catching the exception, the exception is displaying but not my version, does anyone know in what gridview event and how I can catch and customize this exception? what i have now (but not working ) is:
I have a function that checks for a username and if it finds the username it will allow the user to update the user, there are 3 main columns: Name,Age,isFemale. I have the enduser supply the information and then I try to update the record but I get a sql error for "not a valid" column.console app:
[Code]....
I pass the spIsFemale by using an enum, here is the Person Class with function. [Code]....
I get an error that column isFemale is not valid. The isFemale column is a bit type. If it's a 1, it's a female, if 0 male. this is more of a test area and I'm trying to update records or create new one's if the name does not exist.II am new to C # and I am just trying to learn new ideas and methods within C sharp.
If I want to access the method in which we define update query, how can I access that method on aspx page & update the data in a grid view without direct use of an query on aspx page under sql data source?
I am trying to get a parameter for my update from the gridview but it is an ID column that I do not want displayed. If I display the data in a boundfield it works fine but if I set the visibility to false the parameter is no longer sent to the update stored procedure. There does not appear to be a hiddenfield column that I can put into the gridview.I have tried to set the parameters through the code behind but I am not certain on how to access the data I want the following code does not work (It sets the parameter to nothing
Protected Sub grvFacilityDisciplineBillingRate_RowUpdating(ByVal sender As Object, ByVal e As GridViewUpdateEventArgs) Handles grvFacilityDisciplineBillingRate.RowUpdating Dim row As GridViewRow = grvFacilityDisciplineBillingRate.Rows(e.RowIndex)[code]...
And this is the front end with the two ID columns displayed, which is not what I want
im trying this query but i get a error at the very end of the statement at [BookingNumber] ---- The error IS: Incorect Syntax near [BookingNumber]
"UPDATE ["+txtDBNameSql+"].[dbo].[Bookings] SET [ItemPrice]="+Price+",[ItemCode]="+Code+",[Status]="+Status+",[Clientescription]="+ClientDesc+",[ArrivalDate]="+arrival.ToShortDateString()+",[DepartureDate]="+depature.ToShortDateString()+",[DurationCharged]="+Nights+",[ClientCode]="+clientCode+" WHERE [BookingNumber]="+WebBookingNo+""
i am using a gridview which shows the data and a select column. when the user selects a record a detailsview is shown with the respective details and an edit button inside it. when the user clicks on the edit button the entire detailsview becomes editable and the user can now edit the selected record .here the problem starts cause when the user clicks on the update button there is an error stating that illegal variable/number or parameter not found.i am using sqldatasource to bind the gridview and detailsview with an unique RequestId fieldwhich detailsview sql datasource uses to bind the record uniquely.
I'm trying to do updates into for a table with checkbox and number value type from the search page but there is problem with my update statement.Problem with the code: Unable to perform an update, datatype mismatch.
there is a field in my table WATERMARKED_IMAGE which is null at present...i want to insert value in that column....at the same time i want to update a column FLAG.
so should i use insert or update query??
SqlCommand storeimage = new SqlCommand("update WATERMARKED_IMAGES set WATERMARKED_IMAGE=@bmp,FLAG=@flag where (WID='" + wid + "' )", connection); storeimage.Parameters.Add("@bmp", SqlDbType.Image,bmp.Width).Value = imtobyte; storeimage.Parameters.Add("@flag", SqlDbType.Int, 50000).Value = Flag;
