What is the difference between DateTime and DateTime2?

The main difference is the way of data storage: while in Datetime type, the date comes first and then time, in Datetime2, 3 bytes, in the end, represents date part! Depending on precision, Datetime2 takes between 6 and 8 bytes of storage.

What is datetime2 in C#?

The . Net datetime is isomorphic with the SQL Server datetime2 type – the range of possible values is the same. It happens when you do not provide a value for a datetime in your C# (or VB) code which is to be stored in a non-nullable datetime field in the database.

How accurate is datetime now?

First, lets take a look at precision: The DateTime type is basically just a 64 bit integer that counts “ticks”. One tick is 100 nanoseconds (or 0.0001 milliseconds) long (MSDN). So DateTime ‘s precision can be up to 0.0001 milliseconds.

Should you use datetime2?

The MSDN documentation for datetime recommends using datetime2. Here is their recommendation: Use the time , date , datetime2 and datetimeoffset data types for new work. datetime2 has larger date range, a larger default fractional precision, and optional user-specified precision.

Do you have to convert Char to datetime in SQL?

If the point is to enter the char data into a datatime column in the database, you don’t need to convert the value to a datetime (assuming it’s a valid date), since the conversion is implicit.

What happens if I try to convert varchar to datetime?

How to convert Char to date in VBScript?

Generally, in a situation like this, I’d validate in the application that it’s a date (i.e., in a VB/VBScript you could use the isDate function to test the value and reject it if not in a date format) before attempting to store it in the DB. So you could use one of the following CONVERT functions: I hope that helps you.

Is the date and time format compatible with datetime2?

The ANSI and ISO 8601 compliance of date and time apply to datetime2. Some down-level clients do not support the time, date, datetime2 and datetimeoffset data types.
