如何在 sql 查询中传递 python 列表代替 *

Question

我有这种类型的 sql 字符串

"""select {}  from public."myTempTable" where desc_id in (select desc_id from projectapp_description_table)
Except 
select  {}   from projectapp_sitelink_table"""

我想在括号中传递一个 python 列表以执行

Answer 1

尝试这样的事情：

column_list = ['id', 'user', 'value']

my_string = 'select {0} from public.myTempTable where desc_id in (select desc_id from projectapp_description_table) ' \
            'Except ' \
            'select  {0} from projectapp_sitelink_table'.format(", ".join('%s' % col for col in column_list))

print(my_string)
