                  问题描述

                  在 Oracle PL/SQL 中创建过程(或函数)时,不能指定 varchar2 参数的最大长度,只能指定数据类型.例如

                  When you create a procedure (or a function) in Oracle PL/SQL, you cannot specify the maximum length of the varchar2 arguments, only the datatype. For example

                  create or replace procedure testproc(arg1 in varchar2) is
                  begin
                    null;
                  end;
                  

                  您知道在 Oracle 中可以作为 arg1 参数传递给此过程的字符串的最大长度吗?

                  Do you know the maximum length of a string that you can pass as the arg1 argument to this procedure in Oracle ?

                  推荐答案

                  PL/SQL 程序中可能高达 32KB

                  In PL/SQL procedure it may be up to 32KB
