[英]loop sql query in a bash script
I need to loop a oracle sqlplus query using bash. 我需要使用bash循环oracle sqlplus查询。
my scenario is like this. 我的情况就是这样。 I have a set of names in a text file and i need to find out details of that names using a sqlplus query. 我在文本文件中有一组名称,我需要使用sqlplus查询找出该名称的详细信息。
textfile.txt content: textfile.txt内容:
john
robert
samuel
chris
bash script bash脚本
#!/bin/bash
while read line
do
/opt/oracle/bin/sqlplus -s user@db/password @query.sql $line
done < /tmp/textfile.txt
sql query: query.sql sql查询:query.sql
set verify off
set heading off
select customerid from customers where customername like '%&1%';
exit
problem is when I run the script I get errors like 问题是当我运行脚本时出现类似以下错误
SP2-0734: unknown command beginning "robert..." - rest of line ignored. SP2-0734:未知命令以“ robert ...”开头-其余行被忽略。
can someone tell me how to solve this? 有人可以告诉我如何解决吗?
The way I do this all the time is as follows: 我一直这样做的方式如下:
#!/bin/bash
cat textfile.txt |while read Name
do
sqlplus -s userid/password@db_name > output.log <<EOF
set verify off
set heading off
select customerid from customers where customername like '%${Name}%'
/
exit
EOF
Bash will auto magically expand ${Name} for each line and place it into the sql command before sending it into sqlplus Bash将自动神奇地扩展每一行的$ {Name}并将其放入sql命令中,然后再发送至sqlplus
Do you have set define on
? 您是否已将set define on
? Is your wildcard &
? 是您的通配符&
吗? You could check glogin.sql
to know. 您可以检查glogin.sql
来了解。
And yes, establishing n
connections to pass n
queries is probably not a good solution. 是的,建立n
连接以传递n
查询可能不是一个好的解决方案。 Maybe it's faster for you to develop and you will do that one time, but if not, you should maybe think of crafting a procedure. 也许对您来说开发起来会更快,并且您会一次完成,但是如果没有,您应该考虑制定一个过程。
