3Correction
3The example CREATE TABLE statement should have a data type defined for the 3fourth column (c4). The statement is changed to the following:
3   CREATE TABLE T1(c1 INT, c2 DOUBLE, 
3                   c3 DOUBLE GENERATED ALWAYS AS (c1 + c2),
3                   c4 SMALLINT GENERATED ALWAYS AS 
3                     (CASE
3                        WHEN c1 > c2 THEN 1 
3                        ELSE NULL
3                      END)

3Correction
3The following limitations for ADO applications are added: 3
  • 3When inserting a new row using a server-side scrollable cursor, use the 3AddNew() method with the Fieldlist and Values arguments. This is more 3efficient than calling AddNew() with no arguments and with Update() calls for 3each column. Each AddNew() and Update() call is a separate request to 3the server and therefore, is less efficient than a single call to 3AddNew().
  • 3Newly inserted rows are not updateable with a server-side scrollable 3cursor.
  • 3Tables with long data type, LOB, or Datalink columns are not updateable 3when using a server-side scrollable cursor. 3
