Using MIME types The Multipurpose Internet Mail Exchange (MIME) type describes how a Web browser or mail application handles files received from the server. For example, when a Web browser requests an item on a server, the MIME type of the object is also requested. Some MIME types, such as graphics, can be displayed i

into a single server cluster using system software. In cluster mode, all blades can be connected to provide a high-speed network environment, share resources, and serve the same user base. By inserting new blades into the cluster, you can improve overall performance. Because each blade is hot-swappable, the system can be easily replaced and the maintenance time minimized.Blade servers are more space-saving than rack-mounted servers, and thermal issue

Label:Differences between text and varchar (max) data types in SQL ServerIt was only known that text and image were data types that could be retired by SQL Server, but it was not clear why the difference between text and varchar (max) and nvarchar (max) was found in reading today, mainly the restriction of operators. Text can only be used by the following functio

: Rounding to the nearest value, rounding up, downloading, and rounding to zero. Microsoft SQL Server uses top rounding. All values must be accurate to the specified precision, but small floating point values may change. Because the binary representation of floating point numbers can use any of the many valid rounding rules, it is impossible for us to reliably quantify a floating point value.Convert decimal and numeric data ForDecimalAndNumericData Ty

1. instance reproduction of four types of transaction concurrency problems in SQL Server Zhu Er (2006.3 reproduced please note the author) http://blog.csdn.net/netcoder/article/details/633153This articleArticleIt will use instances to reproduce four types of concurrency issues in database access, hoping that beginners can have a better understanding of transacti

that a transaction is reading. The row range for the first read of a transaction shows that one row has ceased to exist in the second or subsequent read because the row has been deleted by another transaction. Similarly, because of the insert operation of another transaction, the second or subsequent read of the transaction shows a row that does not exist in the original read.All four of these problems can cause inconsistencies in the data. The level at which we prepare transactions to accept i
