oracle的异常
让心灵去旅行 · 2005-12-13 · via 博客园 - 让心灵去旅行

一、在plsql中,oracle自带的Exceptions如下:

Exception Oracle Error SQLCODE Value
ACCESS_INTO_NULL ORA-06530 -6530
CASE_NOT_FOUND ORA-06592 -6592
COLLECTION_IS_NULL ORA-06531 -6531
CURSOR_ALREADY_OPEN ORA-06511 -6511
DUP_VAL_ON_INDEX ORA-00001 -1
INVALID_CURSOR ORA-01001 -1001
INVALID_NUMBER ORA-01722 -1722
LOGIN_DENIED ORA-01017 -1017
NO_DATA_FOUND ORA-01403 +100
NOT_LOGGED_ON ORA-01012 -1012
PROGRAM_ERROR ORA-06501 -6501
ROWTYPE_MISMATCH ORA-06504 -6504
SELF_IS_NULL ORA-30625 -30625
STORAGE_ERROR ORA-06500 -6500
SUBSCRIPT_BEYOND_COUNT ORA-06533 -6533
SUBSCRIPT_OUTSIDE_LIMIT ORA-06532 -6532
SYS_INVALID_ROWID ORA-01410 -1410
TIMEOUT_ON_RESOURCE ORA-00051 -51
TOO_MANY_ROWS ORA-01422 -1422
VALUE_ERROR ORA-06502 -6502
ZERO_DIVIDE ORA-01476 -1476

以上没有列出的oracle error可以通过如下方式截获
when others then
if sqlcode=[需要处理错误的oracle error code value] then
...
end if

二、自定义异常,示例如下:
--申明
DECLARE inventory_too_low EXCEPTION;
--抛出
IF order_rec.qty>inventory_rec.qty THEN
RAISE inventory_too_low;
END IF
--截获
EXCEPTION
 WHEN inventory_too_low THEN
 END;
