在SQL*PLUS下执行一个脚本 ，里面是INSERT 语句，如果遇到主键重复错误，后面的SQL语句是否还继续执行??

后面的SQL语句能否执行，是可以通过SQLPLUS的设置的。

默认是不退出 ，继续执行下面的SQL语句。

C:\>sqlplus scott/tiger@test

设置 了WHENEVER SQLERROR EXIT  那么当出现错误的时候，SQLPLUS将会退出。

默认是 WHENEVER SQLERROR CONTINUE

SQL> whenever --help
用法: WHENEVER SQLERROR
{ CONTINUE  [ COMMIT | ROLLBACK | NONE ]
     | EXIT  [ SUCCESS | FAILURE | WARNING | n | | : ]

             [ COMMIT | ROLLBACK ] }

用法: WHENEVER OSERROR
{ CONTINUE  [ COMMIT | ROLLBACK | NONE ]  |  EXIT [ SUCCESS | FAILURE |
         WARNING | n | | : | OSCODE ]
             [ COMMIT | ROLLBACK ] }

这个选项还蛮多的，还可以设置whenever sqlerror  continue rollback; 遇到错误回滚前面的。下面的还可以继续提交。类似

ROLLBACK TO SAVEPOINT
