[如何使用Python Flask和PyOdbc将内部查询用作select语句，将值插入表中？从HTML表单获取的内部查询的输入

Question

环境详细信息。 Windows 10-Python3.5-Flask-SQL SERVER-PyOdbc。

cur.execute("insert into T1 (ID_CUSTOMER, ID_ENVIRONMENT) values (?, ?)",
                    select id from CUSTOMER where name = form['customerId'],
                    select id from ENVIRONMENT where name = form['environmentId'],
                    )

Answer 1

删除values，您可以直接使用INSERT SELECT。

INSERT INTO T1 
            (ID_CUSTOMER, 
             ID_ENVIRONMENT) 
SELECT ID_CUSTOMER =(SELECT Max(id) 
                     FROM   customer 
                     WHERE  NAME = 'abc'), 
       ID_ENVIRONMENT = (SELECT Max(id) 
                         FROM   environment 
                         WHERE  NAME = 'xyz') 

Max(id)是为了确保内部查询返回单个值
