[英]Echo sqlplus command without using prompts or scripts
我有一个我想作为单个文件维护的脚本,但是我希望在不使用PROMPT <sql>
或@script.sql
输入到 sqlplus 中的命令,这可以完成吗?
当前脚本:
$ cat test.sh
#!/bin/bash
LOG=/home/oracle/output.log
sqlplus hr/hr <<EOF > $LOG
set echo on
select 1 from dual;
QUIT
EOF`
当前output:
$ cat output.log

我想要的是:
$ cat output.log

当SQL * Plus从TTY中读取命令时,输入的回声实际上是由TTY处理的,而不是由SQL * Plus处理的。 如果SQL * Plus处理了回显,则每次您手动键入命令时,都会看到该命令两次(键入一次,回显一次)。
此外, TERMOUT
选项仅在运行脚本文件时适用,而不能从STDIN中读取。
简单的解决方法是告诉SQL * Plus /dev/stdin
是一个脚本:
sqlplus scott/tiger @/dev/stdin <<EOF
SET TERMOUT ON ECHO ON
SELECT SYSDATE FROM dual;
EOF
尝试spool
而不是重定向您的STDOUT:
#!/bin/bash
LOG=/home/oracle/output.log
sqlplus hr/hr <<EOF
set echo on term on
spool $LOG
select 1 from dual;
QUIT
EOF
扩展精彩的@Mr.llama 答案。 他的构造在 Solaris 上运行完美。
但是在 Linux(Oracle Linux 服务器版本 7.9)上,这会导致每个命令在 sqlplus 中运行两次,即使它只回显命令一次。 见下文:
$ sqlplus -l / as sysdba @/dev/stdin <<-EOF
> set echo on termout on
> select systimestamp from dual;
> EOF

请注意有两条 systimestamp 行,它们具有不同的时间戳,这意味着 select 被执行了两次。
当同一块在 Solaris 上运行时,不会发生这种双重执行。
Linux 解决方法是将构造修改为:
$ cat /dev/stdin <<-EOF | sqlplus -l / as sysdba @/dev/stdin
> set echo on termout on
> select systimestamp from dual;
> EOF
