Unbound column - use GetChunk (Error 40036)

You attempted to access a column containing a large binary object (BLOB) or similar object.

To avoid this error, use the GetChunk method to access columns of this type. If this error occurs when using parameters, you cannot use parameters on columns that represent large binary objects (Text or Image columns in SQL Server). You can use the ChunkRequired property to determine if the column in question requires the use of GetChunk.
