Returns a Boolean value that indicates if data must be accessed using the GetChunk method.
Syntax
object.ChunkRequired
The object placeholder represents an object expression that evaluates to an object in the Applies To list.
Return Values
The ChunkRequired property return values are:
| Value | Description |
| True | The data should be accessed using the GetChunk method. |
| False | The data need not be accessed using the GetChunk method. |
Remarks
Use the ChunkRequired property to determine if the column in question should be manipulated using the AppendChunk and GetChunk methods. Accessing the Value property of a column whose ChunkRequired property is True, will only result in a trappable error when RDO is unable to fetch the data without use of the AppendChunk or GetChunk methods. In other words, when the data column does not contain more data than can be handled by conventional string handling, you are not required to use the GetChunk and AppendChunk methods.
By setting the BindThreshold property, you can adjust the number of bytes that will force the use of the AppendChunk and GetChunk methods. You can also determine the length of a chunk column by using the ColumnSize method.
