Question

我正在寻找如何控制大型sql脚本执行的技巧。它将包含各种DDL和DML语句。大多数情况下，我一直在寻找DDL控件。我的意思是，基本上我有一个脚本，其中包含多个DDL语句，这些语句是从我们的一个DB生成的。当我启动脚本时，即使在创建时出现编译错误或错误，它也会通过。感谢任何想法

您想在错误后退出吗？这是一些例子。请务必查看WHENEVER SQLERROR。

的文档

DDL（DML）示例：

prompt continues after error
prompt =====================
prompt

create table foo;

prompt quits after error with error code 
prompt =================================
prompt

whenever sqlerror exit sql.sqlcode

create table foo;

prompt never gets here
prompt ===============
prompt

quit

PL / SQL子程序引发了一个异常：

create or replace function foo return number as
  foo_error exception;
begin
  raise foo_error;
end;
/
show errors

prompt continues after error
prompt =====================
prompt

select foo from dual;

prompt quits after error with error code 
prompt =================================
prompt

whenever sqlerror exit sql.sqlcode

select foo from dual;

prompt never gets here
prompt ===============
prompt

quit

PL / SQL单元编译失败：

create or replace procedure compile_function (f in varchar2) as
begin
  execute immediate 'alter function :f compile' using f;
exception
  when others then
    raise_application_error(-20000, 'Failed to compile function ' || f);
end;
/
show errors

prompt continues after error
prompt =====================
prompt

create or replace function foo return number as
begin
  compilation will fail
end;
/
show errors

exec compile_function('foo')

prompt quits after error with error code 
prompt =================================
prompt

whenever sqlerror exit sql.sqlcode

create or replace function foo return number as
begin
  compilation will fail
end;
/
show errors

exec compile_function('foo')

prompt never gets here
prompt ===============
prompt

quit

SQL脚本执行控制
