SQL Server :: Data Types Uniqueidentifier Specified Cast Is Not Valid?
Nov 16, 2010
have a table that keeps track of customer data that is beyond the scope of the Membership Class, this table I am also using the Membership.CreateUser() generated user ID.When I use my INSERT statement however to create a new row in my table I keep getting the Specified cast is not valid error.This is my SQL Command (The ...refer to other fields)
Dim mySqlCommand As String = "INSERT INTO Customers (UserID, ...) VALUES (@UserID, ...)"
I send it to my Write_Database(mySqlCommand, Membership.GetUser(txtUserName.Text).ProviderUserKey, ...) function which then
I also tried sending he UserID as: CType(Membership.GetUser(txtUserName.Text).ProviderUserKey, SqlGuid)
Neither Works...both cause errors...My Write_Database Function is declared as follows:
Public Function Write_Database(ByVal MysqlQuery As String, ByVal UserID As System.Data.SqlTypes.SqlGuid, ...)
However Visual Studio shows that the error originates in the function calling code...
I've got a list of teams which seperate into different leagues. I'm trying to show the user the league that they are in and show it from where they are in the league. This is the error I'm recieving:Specified cast is not valid.

I have a .Net 2 solution with some asp classic pages.I get a specified cast is not valid error when I access the page on my local. Below is the vb function where I get the Error:
Public Function Retrieve(ByVal vntSeqId As String, ByRef vntPart As String, ByRef vntPartKey As String, ByRef vntEntDate As String _ , ByRef vntStatus As String, ByRef vntOrigGblId As String, ByRef vntOrigNetId As String, ByRef vntOrigName As String, ByRef vntOrigPhone As String _ [code]...
At first, I thought the problem is with the source code and we were thinking the source code we have is different with the ones deployed on test and prod servers. But when I tried to upload it on the test server, I don't get the specified cast is not valid error.

There are two dropdowns for date (Fromdate and Todate) in my webpage and by default when the page loads for the first time the dropdowns loads with the last date (currentdate), if I select some previous date in Fromdate dropdown and reload the page then it displays runtime i.e.

Following code is written under GridView RowDataBound Event.
I fruther want to inform that some columns in the grid are showing 0 if there is no record but I replaced 0 to - then some 0s replaced and some not. What is the reason?
There is select and update SQLs in sqldatasource and checkbox in formview which is 2way databinded to an sqlserver bit field type.
it always gives same error
Specified cast is not valid
I excpect nobody posts me an "eval" solution.because update is a need for checkboxes which are attached to a bit field.

At the moment I'm trying to keep a certain site (asp.net) alive long enough for its replacement to be build in php. However I don't know much about .net or asp.net.
We are getting this error:

select SUM(PETTYAMOUNT) AS tot FROM FINPETTY WHERE PETTYAMOUNT IS NOT NULL AND CENTER = '1' if (drReadera.HasRows) { double totamta = Convert.ToDouble(drReadera["TOTALSUMA"]); Label2.Text = String.Format("{0:N2}", totamta); }
note: some of the pettyamount is null that's why i've got an error in page.
I've already checked the row returned by my sproc and all the fields match my OcItemConstraintDetails class. Not sure why I am getting the error below :(Error: Specified cast is not valid.
I have a webpage, i have a usercontrol in it , its name ispersonal1, i have tow Radiobutton in this usercontrol, the id of one of them ismale and the other one is female, it is obviously that each time we fill one of these radiobuttons and the other one will be null,in my database the type of these fields are bit , and they have allow null, i defined a property for my usercontrol like this:
just needing a 2nd set of eyes looking at this to make sure the error isn't something else other than my LINQ code here. Here's the function class itself:

For some reason it's flagging the 2nd line in the GetJacketByPolicyID function saying the specified cast is not valid. So I'm guessing it's something I'm doing wrong. I'm sure the tblPolicy/tblPolicies class works right since I can create a new instance of a tblPolicy and set a few variables by hand and return it, so that's not it. I've also checked the datarow I'm fetching and there's no null values in the record, so that shouldn't be it either.
I have a complicated join between a few tables but I have managed to replicate the error using linqpad and the small tables below. There are references between the COLNAME column and the YAXIS column and also between COLNAME and XAXIS that is not explicitly defined.
The error is "Specified cast is not valid", which originally I wasted time thinking the problem was converting the data returned to my object in VS 2010, but the error also happens in linqpad with no defined object. It seems insane that a bit column would cause this problem. If I change the column type to a VARCHAR it works fine. If I run the generated SQL from linqpad or sql profiler that also returns fine.
I have a custom oledb role provider that pretty much a cust and past of:
[URL]
except I've used oledb instead of odbc. I'm connecting to an oracle database and the tables have been created with out any issues. now if I go into the Website Administration Tool and try to create a new role I get the error
"Specified cast is not valid."
I can create a role directly in the database (through TOAD) and the role will show up in the .NET WAT, so I know it can make the connection and read the info just fine. I just can't create or delete or modify a role without the above error.
Page1 contains GridView1 which displays info from Table1.GridView1 contains a CommandButton which, when clicked inserts the values of all columns, plus a calculated value which goes into an extra column into Table2 handled in the RowCommand event handler of GridView1.Page2 contains GridView2 which displays info from Table2.GridView2 allows the user to alter the value of one of the columns in Table2 using the standard Edit/Update link.All this worked well until...I added UserId and SessionId fields to Table2 (uniqueidentifier and varchar(MAX) respectively,I added the following code to Page1 Code Behind to insert these values from the RowCommand handler:
[Code]....
All of this works beautifully. But... I then added this code to GridView2's RowUpdating event handler:
we have created web application project and on local computer everyting works fine. after doing deployment on our production server we get a error below

The problem is that this is occurring only on our servers, not on our local development boxes. I've tracked it down to a single property we're modifying:
event.SalesForceId = "701Q0000000AOTIIA4";
If I comment out that line, everything works fine.
I've tried:
1 ) waxing all of the code on the server and redeploying. Same issue. 2 ) Pulling down a copy of the server DB and trying it locally. Works fine. 3 ) Trying another IIS environment we have setup on the same box. Same issue. 4 ) Physically comparing ( using AdeptSQL ) both local and remote schemas. No differences. 5 ) Verifying the datatypes of both columns ( local and remote ) are the same. Also, this column is a FK to another table. I verified that both are of the same data type, down to the collation.
The server is Windows Server 2008 and the local box is Windows 7 x64. Both have all important updates setup.
The only thing I can think of is perhaps since the database and web server are on different boxes that could be an issue? Otherwise, I'm completely stumped.
I have two linqTOsql entities that has a parent and child relationship, one to many. I'm running into an issue that when I retrieve the parent record, I am unable to loop through the related records in the child table.This code fails:
I'm using a stored procedure to dump some data into a sql 2008 db. The sp calls a couple of other sp's and it is one of these that is throwing the error 'Operand type clash: uniqueidentifier is incompatible with int'I've stepped through the sp in enterprised studio and entered the values mannually and the last table updates as desired.I've also stepped through the aspx page and all values are passed in ok.
how I can get around the following error with the following code?
[Code]....
Error: Msg 8169, Level 16, State 2, Line 1 Conversion failed when converting from a character string to uniqueidentifier. As you can probably tell, the datatypes are: m.UserId = uniqueidentifier l.System_User_ID = varchar(256) I was hoping the casting of one to the other would solve the issue, but it doesn't. How can I re-code this? I see from other forums it would probably be best to set all these fields to uniqueidentifier, but would prefer not to at this stage as it will involve changing quite a bit throughout the whole site!
