PipelineBuffer.GetColumnInfo Method (Int32)
Assembly: Microsoft.SqlServer.PipelineHost (in Microsoft.SqlServer.PipelineHost.dll)
The BufferColumn contains information about the data stored in a PipelineBuffer column. This information can be used to prevent exceptions that might occur when assigning data to the buffer column. For example, columns with a fixed length such as the DT_STR, DT_TEXT, DT_WSTR, and DT_BYTES data types will fail if the data length is greater than the MaxLength of the BufferColumn.
