To operate SQL server data over the past two days, you need to set the time, minute, and second of a date field, that is, '2017-11-07 16:41:35. the 033 'is changed to '2017-11-07 00:00:00', so I checked the SQL syntax for datetime-type operations on the Internet and found that implementing this function is very simple.

The remarks type can be text, or ntext! Varchar cannot exceed 8000. Ntext The maximum length of Unicode data is (1,073,741,823) characters. Text Server Code The maximum length of non-Unicode data in the Variable Length page is (2,147,483,647) characters. if your remarks are smaller than 8000 bytes, you can use the varchar type. The access method is

data types for 1.SQL server Data class is a property of data that represents the type of information that the data represents. Any computer language defines its own data type. Of course, different programming languages have different characteristics, the types of data defined and the names are more or less different.

There is no single Boolean storage class in the SQLite database, and the Booean value is stored in integers 0 (false) and 1 (true), and by the time I practice, a Boolean has three states, 0 (FALSE) 1 (true), and null, as shown in the following illustration, After the following INSERT statement, the test can be inserted successfully. And, by SELECT * from stu where flag = "Database" Query to t
