我看到在 oracle 中编写过程的语法如下
PROCEDURE name [ ( parameter_list ) ]
{ IS | AS }
[ declarative_part ]
BEGIN -- executable part begins
statement; [ statement; ]...
[ EXCEPTION -- executable part ends, exception-handling part begins]
exception_handler; [ exception_handler; ]... ]
END;
当我应该使用 AS 和 IS 时,有人可以指导我吗?
