[20211126]完善tpt pr.sql腳本.txt
--//tpt提供pr.sql腳本把原來橫向輸出的內容變成縱向輸出，便于閱讀，但是有一個小問題，通過例子說明：
1.環境：

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.測驗：

--//輸出內容太多換行了，
SCOTT@book> @ pr
ERROR:
ORA-01756: quoted string not properly terminated
--//出現ora-01756錯誤，檢查pr.sql腳本，發現使用\字符作為分隔，
0 c clob := q'\
0 declare
999999 \';;
$ grep '\\' usid.sql
substr(s.machine,instr(s.machine,'\')) u_machine,
--//而usid腳本里面正好也有字符\.這樣導致分隔報錯，這樣修改pr.sql選擇一個不常用的字符作為分隔就ok了，選擇那個呢？
--//實際上任何可見的字符都可能出現問題，很簡單選擇一個不可見字符ctrl+g(小喇叭發生聲音，一般代碼不會出現)或者ctrl+f作為分隔.
--//在linux 的vim下通過ctrl+v ctrl+f輸入，
SCOTT@book> @ pr
PL/SQL procedure successfully completed.
--//嗯，沒有輸出，查看代碼可以發現usid.sql腳本里面有&1要替換，修改如下執行：
