3.3.3 Virtual Column Sequence

Mandatory

Specify the sequence/order of the virtual column relative to the other virtual columns in the table.

Rules

• Sequence numbers must be consecutive.
• The sequence number is automatically assigned when a virtual column is added. The sequence number is updated when the order of the columns is updated in the list of columns.

Tips & Techniques

• The ordering of the virtual columns can be resequenced by varying the value in this column.
• The sequence number for virtual columns only applies within the group they are listed in.
