oracle form 触发器执行顺序 触发器执行顺序: 1.当打开 FORM 时: (1)PRE-FORM (2)PRE-BLOCK(BLOCK 级) (3)WHEN-NEW-FORM-INSTANCE (4)WHEN-NEW-BLOCK-INSTANCE (5)WHEN-NEW-RECORD-INSTANCE (6)WHEN-NEW-ITEM-INSTANCE 2.当填写一行记录完成后,光标移动到下一条记录的时候: (1)WHEN-VALIDATE-RECORD (只将填写的记录与数据库中已存在的记录作唯一性的验证,如果只是页面上的数据重复而数据 库中没有与其重复的值则不会报错.) (2)WHEN-NEW-RECORD-INSTANCE (3)WHEN-NEW-ITEM-INSTANCE 3.当点击“保存”时 (1)WHEN-VALIDATE-RECORD (将页面上的所有数据提交到数据库, 若页面上有重复的数据, 则提交第一次时成功但只是将数 据先写到数据库中一类似临时表的地方,在提交第二条重复记录的时候报错,执行事务回滚,原 来执行成功的指令也将被撤消) (2)PRE-INSERT (3)ON-INSERT (4)POST-INSERT (5)POST-FORMS-COMMIT (6)PRE-BLOCK(BLOCK 级) (7)KEY-COMMIT (8)WHEN-NEW-ITEM-INSTANCE 4. 当光标移动到当前数据块中已经显示的行上时: (1)WHEN-REMOVE-RECORD (2)WHEN-NEW-RECORD-INSTANCE (3)WHEN-NEW-ITEM-INSTANCE 当在该行上的不同 ITEM 移动时: (4)WHEN-NEW-ITEM-INSTANCE 5.当要进行修改时(在记录中的某个项上进行了修改时): (1)ON-LOCK 6.在修改完成后进行保存时: (1)WHEN-VALIDATE-RECORD (2)PRE-UPDATE (3)ON-UPDATE (4)POST-FORMS-COMMIT (5)PRE-BLOCK(BLOCK 级) (6)KEY-COMMIT (7)WHEN-NEW-ITEM-INSTANCE 7.删除一条记录时: (1)ON-LOCK (2)WHEN-REMOVE-RECORD (3)KEY-DELREC (4)WHEN-NEW-RECORD-INSTANCE (5)WHEN-NEW-ITEM-INSTANCE 8.F11 查询过程: (1)WHEN-CLEAR-BLOCK (2)WHEN-NEW-RECORD-INSTANCE (3)WHEN-NEW-ITEM-INSTANCE 在输入查询条件后点 CTRL+F11: (4)PRE-QUERY (5)WHEN-CLEAR-BLOCK (6)POST-QUERY (7)WHEN-NEW-RECORD-INSTANCE (8)WHEN-NEW-ITEM-INSTANCE 9.CRRL+F11: (1)WHEN-CLEAR-BLOCK (2)PRE-QUERY (3)WHEN-CLEAR-BLOCK (4)POST-QUERY(每查一条记录,触发一次) (5)WHEN-NEW-RECORD-INSTANCE (6)WHEN-NEW-ITEM-INSTANCE 10.从查询状态(F11)转为输入状态(F4)时: (1)WHEN-CLEAR-BLOCK (2)KEY-EXIT (3)WHEN-NEW-RECORD-INSTANCE (4)WHEN-NEW-ITEM-INSTANCE 11.手电筒查询过程: (1)QUERY_FIND(BLOCK 级) 输入查询条件后,点击“查询”按钮: (2)WHEN-CLEAR-BLOCK (3)PRE-QUERY (4)WHEN-CLEAR-BLOCK (5)POST-QUERY (6)WHEN-NEW-RECORD-INSTANCE (7)WHEN-NEW-ITEM-INSTANCE 12.点击“New”时: (1)WHEN-NEW-RECORD-INSTANCE (2)WHEN-NEW-ITEM-INSTANCE 13.点击“Edit Field”时: (1)KEY-EDIT 14.点击“Window Help”时: (1)KEY-HELP 15.点击“Clear Record”时: (1)WHEN-REMOVE-RECORD (2)POST-QUERY (3)WHEN-NEW-RECORD-INSTANCE (4)WHEN-NEW-ITEM-INSTANCE 16.点击 F4 关闭时: (1)KEY-EXIT (2)POST-FORM 17.点击“Close Form”按钮关闭时: (1)KEY-EXIT (2)POST-FORM 18.点击“Translations”按钮时: (1)TRANSLATIONS 19.点击小叉号关闭时: (1)WHEN-WINDOW-CLOSED (2)CLOSE-WINDOW (3)KEY-EXIT (4)POST-FORM 20.选中 LOV 列表: (1) KEY-LISTVAL (2) WHEN-NEW-ITEM-INSTANCE 21.选中记录前面的小条时: (1)WHEN-NEW-RECORD-INSTANCE (2)WHEN-NEW-ITEM-INSTANCE(数据项级) (3)WHEN-NEW-ITEM-INSTANCE 22.光标上下移动时 (1)WHEN-NEW-RECORD-INSTANCE (2)WHEN-NEW-ITEM-INSTANCE 23.执行"SHIFT + F6"时: (1)KEY-DUPREC
