Columns Collection (ADOX)

 

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

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.

System_CAPS_noteNote

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.
