The information in this article applies to:

- Microsoft Visual C++, 32-bit Enterprise Edition, version 6.0 
- Microsoft SQL Server 2000 (all editions) 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you use Visual C++ 6.0 to run or debug a SQL Server 2000 stored procedure
with a sql_variant type input parameter, the following error message occurs:

  "22001[Microsoft][ODBC SQL Server Driver]String data, right truncation"

MORE INFORMATION
================

Microsoft SQL Server 2000 introduces a new data type called sql_variant. You can
use the sql_variant data type to store values of various SQL Server-supported
data types except text, ntext, image, timestamp, and sql_variant. In Visual C++
6.0, you cannot run or debug a SQL Server 2000 stored procedure with an input
parameter of type sql_variant.

Steps to Reproduce Behavior
---------------------------

1. Create a new Database Project in Visual C++ 6.0.

2. Switch to the project's Data View.

3. From the Insert menu, click New Database Item. This opens the Insert Database
  Item dialog box. Select Stored Procedure from the Database Item list box, and
  then click OK.

4. In the Edit window, create a stored procedure as follows:

  Create Procedure Test @test sql_variant
  As
  return 5

5. Execute or debug the project.

6. A message box appears with the following error message:

  "22001[Microsoft][ODBC SQL Server Driver]String data, right truncation"
