You can use the IColumnsInfo::GetColumnInfo OLEDB function to return column metadata from a provider. When you use SQL Server 2000, a call to the IColumnsInfo::GetColumnInfo function gives incorrect results when you use server side cursors and prepared SELECT statements. For example, if there is a change in the table schema in between the calls to the function, GetColumninfo still returns the column information of the old table schema.
