将参数传递给 MySQL 脚本命令行
是否有任何选项可以将参数从命令行传递到 MySQL 脚本?
Is there any option to pass a parameter from the command line to MySQL script?
在这个例子中类似于@start_date:
Something like @start_date in this example:
mysql –uuser_id -ppassword –h mysql-host -A -e
"set @start_date=${start_date}; source ${sql_script};" >${data_file};
推荐答案
在网上找到了答案 此处.
基本上,假设我们要运行这个查询:
Basically, suppose that we want to run this query:
Select c_id, c_first_name,c_last_name, c_address,last_modified_date
from customer
where last_modified_date >=@start_date and last_modified_date <= @end_date;
我们可以像这样传递 'start_date' 和 'end_date':
We can pass 'start_date' and 'end_date' like this:
/usr/bin/mysql –uuser_id -ppassword –h mysql-host -A \
-e "set @start_date=${start_date}; set @end_date=${end_date};\
source ${sql_script};" > ${data_file}
