Cast From String &"&" To Type 'Date' Is Not Valid

Mar 12, 2006

Hello, I am using an SQLDataReader called DrCoInfo to check if any matching records exist in a table.

My code is as such:

Line 119:DrCoInfo = comm1.ExecuteReader()
Line 120:While DrCoInfo.Read()
Line 121: If DrCoInfo("DateOfMan") <> "" Then
Line 122: BValid = True
Line 123: End If

However, it fails to work with the message :System.InvalidCastException: Cast from string "" to type 'Date' is not valid.

Any suggestions? Thanks.

Type Cast Error Converting From Integer To String

Oct 30, 2007

I am attempting to convert an integer value to a string using the Derived Column transformation with the following expression on the field:
(DT_STR,10,1252)prod_id

prod_id is an integer. I was able to do this before however, in the past couple of days, this has failed with the following error:
"An error occurred while attempting to perform a type cast."


To my knowledge, I have not changed anything about this particular data flow within the past couple of days. I have verified that the value is coming in as an integer.

Any help would be greatly appreciated.

Specified Cast Is Not Valid

Sep 11, 2006

im doing a sum on a table and it either returns a number in decimal format or 'null' .  The problem is when it returns null i want it to just make the text say '0.00'.  So i did a test on the object that if it returns NULL just print  '0.00' but if it is not null it tells me that there is a number there and i want to store that as a decimal and print it out.  But i get an error for a type cast when im not it should not even be going to that part of the code. In the code below the first executescaler will return null so it should just go straight to the else.  But it gives me the type cast error in the if that shouldnt be seen.  The error and code are below. //Borrower NSF FEES
cmd.CommandText = "select sum(itemamount) from postmtdtls where loanid='" + LoanID + "' and Transactioncode = '310'";

Specified Cast Is Not Valid

Apr 7, 2006

Can't seem to find why I'm getting this error: Specified cast is not valid.
Ok, using a stored procedure for SQL Server 2000 and here is the main part of it:
 SELECT id, rank, firstName, lastName, service, status, createdTime FROM   accessRequest WHERE  lastName LIKE @tLastName     AND    firstName LIKE @tFirstName
And the C# code behind from the class file:
SqlDataReader spResults;
conn.Open();
spResults = command.ExecuteReader();
while( spResults.Read() )
{
AccessRequestSearch request = new AccessRequestSearch( (int)spResults.GetInt32( 0 ), spResults.GetString( 2 ), spResults.GetString( 3 ), spResults.GetString( 1 ), spResults.GetString( 4 ), spResults.GetString( 5 ), Convert.ToDateTime(spResults.GetString( 6 )));
searchResults.Add( request ); // Add to Array List
}
spResults.Close();
The part in red is where I think it's happening because that is what I just added to the request.  createdTime in the table is set as DateTime.
Can anyone see what I am missing here?
More info is available if needed.
Thanks,
Zath

SSRS2000 - Specifies Cast Not Valid

May 2, 2007

Hi,



I get the above error everytime I try to export to Excel; exporting to PDF works fine.



The only way I can get rid of the error is by deleting all the data from within the report (not ideal!). Anyone got any ideas on what could be causing this?



Many thanks,

Converting A Data Type Double To A Type Float Using A Data Adapter &&amp; SSCE 3.5

Feb 13, 2008

Hi,

I can populate a dataTable with type double (C#) of say '1055.01' however when I save these to the CE3.5 database using a float(CE3.5) I lose the decimal portion. The 'offending' code is:


this.court0TableAdapter1.Update(this.mycourtsDataSet1.Court0);

this.mycourtsDataSet1.AcceptChanges();

this.court0TableAdapter1.Fill(this.mycourtsDataSet1.Court0);


This did not happen with VS2005/CE3.01.

I have tried changing all references to decimal (or money in CE3.5) without luck.

I'm beginning to think that string may be the way to go!!!!!!!

Can someone shed some light on my problem.

Thanks,

Later:

It's necessary to update the datatable adapter as the 3.01 and 3.5 CE are not compatible.

I get the following message in the vs2005 querybuilder when i do a preview:



***********************************
SQL Execution Error.

Executed SQL statement: SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = @PARAM1)



Error Source: SQL Server Compact Edition ADO.NET Data Provider


Error Message: @PARAM1 : Unable to cast object of type 'System.Data.SqlTypes.SqlInt32 to type System.IConvertable'.
****************************************

The same querypreview works fine without the parameter:



SELECT Schoolindex, Variant, VVSchool, [index], indincl, VVRuimtes, School FROM School WHERE (Schoolindex = 186)



Can anybody tell me why this is?
And tell me a way to get the tableadapter working?

Unable To Cast COM Object Of Type 'ADODB.CommandClass' To Interface Type 'ADODB._Command'

Dec 20, 2006

I have an application which runs successfully on a couple of my customer's machines but fails on a third. It seems to fail when opening the database:

Unable to cast COM object of type 'ADODB.CommandClass' to interface type 'ADODB._Command'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{B08400BD-F9D1-4D02-B856-71D5DBA123E9}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE)).
Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=false; Initial Catalog=lensdb;Data Source = SQL

Before I got this error I was getting another problem (sorry didn't make a copy of that error's text) that made me think that adodb.dll simply wasn't loaded/registered. I got rid of that error by copying my adodb.dll onto the third machine and running gacutil /i. There is now an entry in winntassemblies for adodb.

Just in case you think it could be an obvious registry problem: when I started getting the current error I thought that maybe the registry needed updating and I merged the following lines into onto the target machine (from my dev machine):

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOTInterface{B08400BD-F9D1-4D02-B856-71D5DBA123E9}]

but, no change alas.

All three machines are running Windows 2000.

Any advice would be appreciated.

Thanks in advance,

Unable To Cast Object Of Type 'System.DBNull' To Type 'System.Byte[]'.

Aug 13, 2007

Hi,
I have developed a custom server control for .NET Framework 2.0. The server control has a property named BinaryData of type byte[]. I marked this property to be data bindable. Now, I have varbinary(Max) type of field in my SQL Database and I have used SQLDataSource and bound this varbinary(Max) field with the property BinaryData (byte[]) of my control. It is working fine as long as the data value is not NULL. Now, In my control, I have handled the NULL value so that no Exception is thrown. Still, when I bind this property using the SQLDataSource, I get Error "Unable to cast object of type 'System.DBNull' to type 'System.Byte[]'." I am not sure if I can do anything to stop this erro within my control. If it is not possible from the control, then what is the workaround that I can do in my ASPX page in order to stop this error ?
Thanks a lot in advance.

Type Cast Problem In SSIS

May 30, 2008

Correct me if i am wrong anywhere.


This is my table structure.


CREATE TABLE [AC].[RUN_PARMS](
[FILE_NAME] [varchar](6) NOT NULL,
[RUN_IND] [bit] NOT NULL,
[GROUP] [varchar](50) NULL,
CONSTRAINT [pk_RUN_PARMS] PRIMARY KEY CLUSTERED
(
[FILE_NAME]
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]


I am using an execute package task in SSIS based on the value of RUN_IND field in RUN_PARMS table. If all the value of RUN_IND field is 0 for all the files in a group, then the execute package task should be enabled else it should be disabled. So i have used the following query.

SELECT SUM(CONVERT(INT,RUN_IND)) AS RUN_IND FROM AC.RUN_PARMS
WHERE [GROUP] = 'FIN'

This will return the value which will be greater than zero. Since i have made the value as 1 for FIN group. Imagine the FIN group has 10 files in it. The output look like,


RUN_IND
10

and

SELECT SUM(CONVERT(INT,RUN_IND)) AS RUN_IND FROM AC.RUN_PARMS
WHERE [GROUP] = 'Ven'

This will return the value which will be equal to zero. Since i have made the value as 0 for Ven group. The output look like,


RUN_IND
0


I have created a variable in the package "user::vardisablepackage".
I have set Resultset as Single for SQL task component
In the package properties (The package which has to be disabled) i have selected property as "Disable" and the expression as @User::vardisablepackage = 0 ?False:True

The problem now is i am not sure what should be the data type for vardisablepackage.
The expression will assign False to Disable property when the RUN_IND = 0.
I am unable to complete this task since i have problem assigning data type for this variable.

Please suggest your views.
