英文:
Running SQL Queries using Shell Script and get back the output in CSV Format
问题
我想使用Shell脚本自动化执行一个包含多个SQL查询的SQL文件，并且同时将它们的输出保存到一个.csv格式的文件中。
还有一个注意事项！这些查询将会有一些可变部分，即它们将会根据用户输入而改变。
例如：
SELECT NAME, CITY, ADDRESS FROM DATA WHERE COUNTRY = 'USA';
在这里，我不希望它始终是USA。那么，有没有办法在Shell脚本中将COUNTRY作为用户输入提供？
英文:
I want to automate a SQL file which contains multiple SQL queries using shell script and in the same time get their output in a .csv format file.
Also there's a catch! These queries will have some variable part i.e they will change and will depend on user input
For Eg:
SELECT NAME, CITY, ADDRESS FROM DATA WHERE COUNTRY = 'USA'
Here i don't want it always to be USA.So is there a way i can provide COUNTRY as a user input in Shell Script?

你可以尝试使用Oracle SQL*Plus替代变量。
SQL脚本 "demo.sql" 如下：
SPOOL some.csv APPEND
set colsep ','
SELECT NAME, CITY, ADDRESS FROM DATA WHERE COUNTRY = '&Country';
SPOOL OFF
然后运行如下脚本：
sqlplus -S username/pass @demo.sql
会提示您输入 "Country"：
输入 "Country" 值：
然后输入一些内容并按回车键。
SQL将被执行，并会生成一个以逗号分隔的 some.csv 文件。
英文:
You could try Oracle SQL*Plus Substitution Variables.
SQL script "demo.sql" like that
SPOOL some.csv APPEND
set colsep ','
SELECT NAME, CITY, ADDRESS FROM DATA WHERE COUNTRY = '&Country';
SPOOL OFF
then run script like that
sqlplus -S username/pass @demo.sql
you will be prompted to input "Country"
Enter value for Country:
then type something and press Enter.
SQL was executed and will get some.csv file separated by Comma.
