The examples in this article describe the SQL Server timestamp feature and usage. Share to everyone for your reference, specific as follows: The concept of timestamp has been blurred, I believe that a lot of friends will also be mistaken: The timestamp is a time field, each time you add data, fill in the current time value.

, and microsecond value are both 0. The TIMESTAMP column is 26 bytes long. String Representation of the datetime value: although the internal representation of the values of DATE, TIME, and TIMESTAMP is transparent to users, the DATE, TIME, and TIMESTAMP can also be expressed in strings, for the CHAR scalar function, see "part of speech parts of speech)" in SQL.

Understanding how DB2 uses memory can prevent over-allocating memory and help tune memory usage for better performance.This article will teach you the basics of DB2 memory usage, as well as the concept of shared memory and private memory. These contents apply to both 32-bit and 64-bit systems. Although there are some limitations on 64-bit systems, they are unlikely to reach these limits for some time to com

Books that are online in SQL Server say this: The SQL Server timestamp data type is independent of time and date.

I was recently depressed by the load type and timestamp of RTP. After debugging for nearly a week, I finally solved the problem. Let's look back, I found that the main reason is that I did not really understand the meaning of the load type and timestamp in the RTP protocol. Although RTP transmission is supported by Jrtplib and Ortp databases, one is the c ++ interface and the other is the c language interfa
