在使用sqlplus执行sql脚本时,经常碰到向脚本传递参数的情形。类似于shell脚本的参数传递,我们同样可以向sql脚本传递参数,其方法是脚本后面直接跟多个连续的参数并以空格分开。本文描述该内容并给出示例。1、SQLPlus 的帮助信息 下面的帮助信息是关于sqlplus调用带参脚本的说明
sqlplus -H
<start> is: @<URL>|<filename>[.<ext>] [<parameter> ...]
Runs the specified SQL*Plus script from a web server (URL) or the
local file system (filename.ext) with specified parameters that
will be assigned to substitution variables in the script.2、shell 提示符下sqlplus调用带参脚本SQL> select * from v$version where rownum<2;BANNER

7788 SCOTT ANALYST--注意,对于含有空格的调用需要使用单引号或双引号,如下示例
[oracle@linux1 ~]$ sqlplus scott/tiger @test.sql emp "bob cheng" old 1: select empno,ename,job from &1 where upper(ename)=upper("&2")
new 1: select empno,ename,job from emp where upper(ename)=upper("bob cheng") EMPNO ENAME JOB
---------- ---------- ---------
8888 Bob Cheng DBA[oracle@linux1 ~]$ sqlplus scott/tiger @test.sql emp "bob cheng"
