在错误抛出的上下文中oracle调用和执行之间的区别

Question

我有一些用Oracle编写的程序.不幸的是我无法显示其代码.其中的某个地方是由于缺少必需的数据而选择执行崩溃的地方.看起来像这样

select value into l_value
        from config
       where code = upper(p_code);

所以当我这样调用这个过程时(在SqlDeveloper中)

execute some_package.some_procedure('CODE');

它抛出

Error report -
ORA-01403: no data found
ORA-06512: at "XXXXXXXXXXXXXXXXXXX", line 111
ORA-06512: at "XXXXXXXXXXXXXXXXXXX", line 111
ORA-06512: at line 1
01403. 00000 -  "no data found"
*Cause:    No data was found from the objects.
*Action:   There was no data from the objects which may be due to end of fetch.

但是当我这样称呼它时

call some_package.some_procedure('CODE');

它崩溃在同一个地方(我可以从结果中建议,存储在DB中),但它没有抛出异常.

some_package.some_procedure('CODE') succeeded.

怎么了？为什么会有这样的差异？

NO_DATA_FOUND异常行为很特殊.它在SQL上下文中默认处理,但在PL/SQL中不处理.在SQL中,没有发现的数据不被视为错误,它一直发生在没有满足特定条件的数据的情况下.

CALL是SQL命令,而是PL/SQL EXEC的快捷方式BEGIN <code> END;.
