在 Oracle 中,语句要么完全成功,要么完全失败(它们是原子的)。但是,您可以在某些情况下添加子句来记录异常而不是引发错误:
第二种方法是全自动的,这里有一个演示(使用 11gR2):
SQL> CREATE TABLE test (pk1 NUMBER,
2 pk2 NUMBER,
3 CONSTRAINT pk_test PRIMARY KEY (pk1, pk2));
Table created.
SQL> /* Statement fails because of duplicate */
SQL> INSERT into test (SELECT 1, 1 FROM dual CONNECT BY LEVEL <= 2);
ERROR at line 1:
ORA-00001: unique constraint (VNZ.PK_TEST) violated
SQL> BEGIN dbms_errlog.create_error_log('TEST'); END;
2 /
PL/SQL procedure successfully completed.
SQL> /* Statement succeeds and the error will be logged */
SQL> INSERT into test (SELECT 1, 1 FROM dual CONNECT BY LEVEL <= 2)
2 LOG ERRORS REJECT LIMIT UNLIMITED;
1 row(s) inserted.
SQL> select ORA_ERR_MESG$, pk1, pk2 from err$_test;
ORA_ERR_MESG$ PK1 PK2
--------------------------------------------------- --- ---
ORA-00001: unique constraint (VNZ.PK_TEST) violated 1 1
您可以将该LOG ERROR
子句与INSERT ALL
(感谢@Alex Poole)一起使用,但您必须在每个表之后添加该子句:
SQL> INSERT ALL
2 INTO test VALUES (1, 1) LOG ERRORS REJECT LIMIT UNLIMITED
3 INTO test VALUES (1, 1) LOG ERRORS REJECT LIMIT UNLIMITED
4 (SELECT * FROM dual);
0 row(s) inserted.
