I am getting exception: "Specific cast is not valid", here is the code
con.Open();
string insertQuery = @"Insert into Tender (Name, Name1, Name2) values ('Val1','Val2','Val3');Select Scope_Identity();";
SqlCommand cmd = new SqlCommand(insertQuery, con);
cmd.ExecuteNonQuery();
tenderId = (int)cmd.ExecuteScalar();

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 .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.
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 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.

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.

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.

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 defined an ODBC Command and ODBCdatareader as follows
OdbcConnection myConnection = new OdbcConnection(connectionString);
OdbcCommand myCommand = new OdbcCommand();
myCommand.Connection = myConnection;
myCommand.CommandText = "select UOPGM from GREG.TUSROPTF";
OdbcDataReader myReader;
myConnection.Open();
myReader = myCommand.ExecuteReader();
When I try to retreive from the reader as follows:
while (myReader.Read())
{
string someString = myReader["UOPGM"];
lstNames.Items.Add(someString);
}
I get the following error
Error reading the database. Unable to cast object of type 'System.Byte[]' to type 'System.String'."
I have also tried string someString = (string)myReader["UOPGM"]; to no avail
I have following code in my class file which returns me the Date field in format like 4/4/2010 12:00:00 AM from SQL SERVER
public IEnumerable Mthgetcomplaintdate()
{
var v = objderma.USP_Patient_Dermatology_Complaints_RepDate(PatientID); ;
return v as IEnumerable;
}
But on my aspx page i want to display only the Date part not time.One way is i will iterated throgh my dropdownlist which am binding with the above method and i convert it using Toshortdatestring() method.But i want to cast the whole Ienumerable result using some method? I have read about cast<> ,but could not understand how to implement it exactly.
I've built a form for entering some data into a table in my database, now I want to INSERT that data, and get back the ID (which is an autonumber) of the record that has just been added. I've got the INSERT part working just fine, and I've tacked "SELECT SCOPE_IDENTITY();" onto the end of that, but now I need to retrieve the returned number. At the moment all of this is done with an SqlDataSource (with the "INSERT" statement being put together and fired by some C# in the codebehind file, which takes data from a form on the page). Is there a quick way to grab that number and put it in a variable?
View 2 RepliesI need to get the id of a record created so that I can store that ifnormation in another SQL table. A snipet of my c#code is as follows:
string insertSql = "INSERT INTO [Group] ([userid], [groupname]) VALUES (@userid, @groupname); SET @groupid = SCOPE_IDENTITY()";
using (SqlConnection myConnection = new SqlConnection(connectionString))
{
myConnection.Open();
SqlCommand myCommand = new SqlCommand(insertSql, myConnection);
myCommand.Parameters.AddWithValue("@userid", currentUserId);
myCommand.Parameters.AddWithValue("@groupname", groupTextBox1.Text);
SqlParameter groupidParameter = new SqlParameter("@groupid", SqlDbType.Int);
groupidParameter.Direction = ParameterDirection.Output;
myCommand.Parameters.Add(groupidParameter);
myCommand.ExecuteNonQuery();
myCommand.ExecuteNonQuery();
gid = (int)groupidParameter.Value;
myConnection.Close();
}
The problem is that I am not getting the @groupid from the SET @groupid = SCOPE_IDENTITY() that is appended to the INSERT statement. The groupid in the SQL table is the Key of type uniqueidentifier
I guess it is too late and I'm too tired to see what I'm doing wrong. Here is what I'm trying:
int imageId = imageDal.AddImage(new SqlParameter[]
{
new SqlParameter("@IMAGE_ID",
SqlDbType.Int, Int32.MaxValue, ParameterDirection.Output,
true, 0, 0,"IMAGE_ID", DataRowVersion.Current,DBNull.Value),
new SqlParameter("@IMAGE",
SqlDbType.Image, 11, ParameterDirection.Input,
true, 0, 0,"IMAGE", DataRowVersion.Current,image)
});
public int AddImage(SqlParameter[] spParams)
{
SqlHelper.ExecuteNonQuery(BaseDAL.ConnectionStringImages, INSERT_IMAGE_SQL, spParams);
return Convert.ToInt32(spParams[0].Value);
}
Stored Procedure:
[dbo].[sp_insert_image]
-- Add the parameters for the stored procedure here
@IMAGE_ID int OUT,
@IMAGE image
AS
BEGIN
INSERT INTO images
(IMAGE)
VALUES
(@IMAGE)
SELECT @IMAGE_ID = SCOPE_IDENTITY();
END
GO
I get DBNull as spParams[0].Value. I've tried setting value of @IMAGE_ID to a constant in my stored procedure yet it didn't change anything so the problem isn't with my stored procedure (that is what I think). When I execute the procedure from sql management studio, I see the inserted_id returning..
