Question

我有一个SQLite数据库，用于存储客户在商店中生成的发票数据。我有一个存储发票号码的表格以及创建它们的日期和时间。日期列的数据类型为TEXT，格式为YYYY-mm-dd hh: MM: ss (2018-02-12 03:02:59)，如下所示。我想根据用户提供的日期过滤结果。如果用户选择2018-02-01作为查询日期，我想显示在2018-02-01 00:00:00到当前日期2017-02-12 23:59:59之间生成的所有发票编号。我在网上搜索了很多但我无法找到相关答案。一些答案说要将整个数据库更改为UNIX纪元时间格式，但在我的情况下现在不可能。我应该如何创建我的选择查询以获得所需的结果？

我使用了以下SQLite命令

SELECT bill_type, bill_amount, bill_date, bill_person_id, _id, partial_amount, bill_payment_status, bill_payment_date FROM bill_data_details WHERE bill_type = 1002 and bill_person_id = 3 and bill_date BETWEEN '2018-02-12 00:00:00 and 2018-02-12 11:59:59' ORDER BY bill_date ASC)

但我的应用程序崩溃并显示错误

Answer 1

使用此查询：

SELECT * FROM YourTableName WHERE DateTimeColumnName BETWEEN UserInputDate AND DATETIME('NOW', 'LOCALTIME')

这将导致所有行的日期时间在当前时间和用户输入的日期之间。 LOCALTIME用于补偿您的时区，SQLite datetime函数使用UTC时区。

在查询中出现错误后编辑问题：
您的查询使用了throws语法错误，因为BETWEEN与AND一起使用，您在单引号内使用了AND。将您的查询修改为：

SELECT bill_type, bill_amount, bill_date, bill_person_id, _id, partial_amount, bill_payment_status, bill_payment_date FROM bill_data_details WHERE bill_type = 1002 and bill_person_id = 3 and bill_date BETWEEN '2018-02-12 00:00:00' AND '2018-02-12 11:59:59' ORDER BY bill_date ASC)

如果您想在查询中使用datetime功能，请将其用作：

SELECT bill_type, bill_amount, bill_date, bill_person_id, _id, partial_amount, bill_payment_status, bill_payment_date FROM bill_data_details WHERE bill_type = 1002 and bill_person_id = 3 and bill_date BETWEEN '2018-02-12 00:00:00' AND DATETIME('NOW', 'LOCALTIME') ORDER BY bill_date ASC)

Answer 2

试试这个：

SELECT bill_type, bill_amount, bill_date, 
bill_person_id, _id, partial_amount, 
bill_payment_status, bill_payment_date FROM 
bill_data_details WHERE bill_type = 1002 and 
bill_person_id = 3 and bill_date BETWEEN
strftime('%Y-%m-%d %H:%M:%S', '2018-02-12 00:00:00') and 
strftime('%Y-%m-%d %H:%M:%S', date('now')) 
ORDER BY bill_date ASC);
