Columns Collection

See Also    Example    Properties    Methods

Contains all Column objects of a table, index, or key.

Remarks

The Append method for a Columns collection is unique for ADOX. You can:

• Add a new column to the collection with the Append method.

The remaining properties and methods are standard to ADO collections. You can:

• Access a column in the collection with the Item property.
  
  
• Return the number of columns contained in the collection with the Count property.
  
  
• Remove a column from the collection with the Delete method.
  
  
• Update the objects in the collection to reflect the current database's schema with the Refresh method.

Note   An error will occur when appending a Column to the Columns collection of an Index if the Column does not exist in a Table that is already appended to the Tables collection.
