"Invalid Character value for cast specification" from VC++ when i execute a proc

Hi Everybody,

I have a question regarding the running of a procedure from VC++ in SQL server.

well this is the scenario.

i have a procedure in SQL server and i am running that thru my VC++ code.
:eek:
i have a recordset class and i create an object of it and then do a obj.Open(). the procedure is fetching 24 records correctly in the query analyser and in my while(!(obj.IsEOF())) loop it gets the first record correctly but the moment it encounters obj.MoveNext(); it bombs and gives me the following error..

"Invalid Character value for cast specification ".

i don't know why this is happening

Thanks for you help.Somewhere in your Transact-SQL code you are trying to convert a character value to another datatype. My first guess would be DATETIME, next might be INT or another numeric datatype. This is usually either in a column you are returning or in a WHERE clause, but it can happen anywhere you can refer to a column.

"Invalid character in the given encoding". XML bulk load, SQLE

Hi Martin,
I confirm that the problem is the presence of the character "è", even if it
is in the comment. How can I solve the problem?
I have put the line
<?xml version="1.0" encoding="utf-8"?>
for the encoding. What else should I do?

Make sure the document is really UTF-8 encoded, with UTF-8 the character
"è" needs to be encoded with the two byte sequence C3 A8.

"Conversion failed when converting from a character string to uniqueidentifier."

This is probably a simple wuestion but i would appreciate some help

I am trying to get and insert theuserId into a table called "Orders"

I got the user id as

Dim CustomerId As Object = Membership.GetUser(User.Identity.Name).ProviderUserKey.ToString

The button on click command is

worldshop.ShoppingCart.CreateOrder(CustomerId,...................

The Function Has the parameter for Customer Id as follows

Dim dbParam_CustomerId As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_CustomerId.ParameterName = "@.CustomerId"
dbParam_CustomerId.Value = CustomerId
dbParam_CustomerId.DbType = System.Data.DbType.String
command.Parameters.Add(dbParam_CustomerId)

When i run this I am getting the error message

"Conversion failed when converting from a character string to uniqueidentifier."

Can anyone tell me where I am going wrong

many thanks

Martin

What type is CustomerID defined as in the database? It sounds like it is NOT a string, but rather a uniqueidentifier (a GUID).|||

thanks for your reply. i got it sorted out

sorry about the delay in getting back to you

I was having the same problem. I solved it by instantiating the userid as an object

Dim userId As Object = Membership.GetUser(User.Identity.Name).ProviderUserKey

i passed the object to the function as a guid

ByVal userId As Guid
Dim dbParam_userId As System.Data.IDataParameter = New System.Data.SqlClient.SqlParameter
dbParam_userId.ParameterName = "@.UserId"
dbParam_userId.Value = userId
dbParam_userId.DbType = System.Data.DbType.Guid
command.Parameters.Add(dbParam_userId)

last i put the guid into the database as char 36

@.UserId char (36)

doesn't work in LIKE wildcards?

I have table of stocks that includes a varchar field that can optionally hold
a formula. You can identify formulas because the first character is "=". You
can also include the names of other stocks in the formula by surrounding the
ticker in !'s. For instance:
=!MSFT! * 2
I need to find all the formulas that do contain a ticker in them, so that I
can look up the stocks they refer to.
The obvious solution is ... WHERE formula LIKE '=%!'. The obvious solution
does not work. Removing the ! returns all the formulas. Anyone know what
would cause this? ! does not appear in the docs as a reserved word or
wildcard.

I think it's the fact that you didn't add a trailing %
where formula like %!%
