Append Structures Do’s and Don'ts

• 1) You create and append structure within the customer name range ( i.e . They should begin with YY or ZZ or za)

• 2) You cannot create an append structure for pool and Cluster table.

• 3) If a table contains a long field (ex. LRAW) then it is not possible to expand it with an append structure since such fields must always be the last fields.

Append Structures Features of APPEND structures

• Append structures allow you to add fields to a table without modifying the table itself.

• It can be assigned only to one particular table. (you can have more than one structure per table).

• When copying tables the fields of the append structure also copied.
