[20211126]完善tpt pr.sql脚本.txt

--//tpt提供pr.sql脚本把原来横向输出的内容变成纵向输出,便于阅读。但是有一个小问题,通过例子说明:

1.环境:
SCOTT@book> @ ver1
PORT_STRING                    VERSION        BANNER
------------------------------ -------------- --------------------------------------------------------------------------------
x86_64/Linux 2.4.xx            11.2.0.4.0     Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

2.测试:
SCOTT@book> @ spid
       SID    SERIAL# PROCESS                  SERVER    SPID       PID  P_SERIAL# C50
---------- ---------- ------------------------ --------- ------ ------- ---------- --------------------------------------------------

--//输出内容太多换行了。

SCOTT@book> @ pr
ERROR:
ORA-01756: quoted string not properly terminated

--//出现ora-01756错误。检查pr.sql脚本,发现使用\字符作为分隔。
0 c clob := q'\
0 declare

999999      \';;

$ grep '\\' usid.sql
       substr(s.machine,instr(s.machine,'\')) u_machine,
--//而usid脚本里面正好也有字符\.这样导致分隔报错。这样修改pr.sql选择一个不常用的字符作为分隔就ok了。选择那个呢?
--//实际上任何可见的字符都可能出现问题,很简单选择一个不可见字符ctrl+g(小喇叭发生声音,一般代码不会出现)或者ctrl+f作为分隔.
--//在linux 的vim下通过ctrl+v ctrl+f输入。

SCOTT@book> @ pr
PL/SQL procedure successfully completed.

--//嗯,没有输出。查看代码可以发现usid.sql脚本里面有&1要替换,修改如下执行:
