bulk

I have a stored procedure which does bulk insert on a SQL server 2005 database. When I call this stored procedure from some SQL (passing in the name of a local format file and data file) it works fine. Every time.

However, when this same stored procedure gets called from C# .NET 3.5 code using SqlCommand.ExecuteNonQuery it works intermittently.

When it fails a SqlException is generated stating "Cannot bulk load. Invalid column number in the format file "c:\bulkinsert\MyFile.fmt"

I don't think this error message is correct.

Has anyone experienced similar problems with calling bulk insert from code?

Thanks.

The dynamic type in C# 4.0 is a welcome addition to the language.
