- Change the Name.
- Select
For Update,
For Insert, or
For Delete to indicate the condition under which the trigger invokes when the associated table is modified.
- (Optional) Enter a description in the
Comments field.
- Specify the trigger event properties:
- Specify the trigger isolation level as either Row Level or Statement Level.
- Specify the trigger firing time as Before, After, or Resolved. The Before and After
options result in the trigger being fired before or after the specified row or statement is altered or executed.
Choosing Resolved
results in the trigger being fired before row-level updates or column updates only and is for use with SQL Remote.
- Specify Insert,
Update, Delete, or Update Column
to indicate the condition under which the trigger is to be invoked when the associated table is modified. Choosing Update column
results in the trigger being fired on column updates.
- For
Trigger Columns, select the columns that you want updated when the trigger is invoked.
- Enter the Order number, which determines the order in which triggers of the same type (insert,
update, or
delete) are fired.
- Specify the data to be referenced:
- Old – if you specify row-level isolation, the name you enter here refers to the values of a row before an update or delete. If you have specified statement-level isolation, the name you enter here refers to
declared temporary tables holding the old and new values of the rows.
- New – if you specify row-level isolation, the name you enter here refers to inserted row values after an update or insert. If you have specified statement-level isolation, the name you enter here refers to
declared temporary tables holding the old and new values of the rows.
- Remote – if you specify the trigger firing time as Resolved, the name you enter here refers to the values in the verify clause of an update statement.
