Label: When the database is relatively large, and when you want to back up, we can start the database backup compression. This is because the backup file is smaller compression, so the entire backup faster, but also lower the consumption of disk space.There is, of course, one aspect. The CPU consumption will definitely be added. Just the general server is multi-core. So there's really no big impact on the system. In fact. Not only can it be compress

Original: SQL Server index and table Architecture (nonclustered index)Nonclustered indexesOverviewfor nonclustered indexes, the information involved is a bit more than the clustered index, because the entire length of the page is much more involved in the next "index of the included column ", "Index fragmentation" and some other knowledge points, may be combined

In the design of database application, we often need to get the total number of records of some tables, to determine whether the total number of records in the table is too large, the need to back up data and so on. Our usual practice is to select COUNT (*) as C from TableA. However, these practices can be time-consuming for a large number of records. Experimenting on the Dell 4400 server, the MS

When the database is larger, and we want to make a backup, we can start the compression of the database backup, thus reducing the consumption of disk space.In fact, not only can be compressed at the time of backup, in SQL Server 2008, we can also compress the table, the following compression and compression before the comparison, to demonstrate the

When using tables in a database, we often encounter two ways to use tables: using temporary tables and table variables. In actual use, how can we flexibly use them in the stored procedure? Although they implement the same functions, in a stored procedure, how does one sometimes use temporary tables instead of table variables, and sometimes use table variables ins

of records per row can only be 8k, which is why char and varchar are limited to 8k in size, and storing more than 8k of data should use the text type. In fact, the text type of the field value can not be directly entered and saved, it is to store a pointer to a number of 8k data page composed of the expansion area, the real data is actually placed in these data pages.When to set the index1. Define a data column for the primary key (SQL

Many friends think that in simple mode, the heap table cannot retrieve a record because there is no log record. In fact, in a sense, it can be recovered, because the heap table only changes the row offset when deleting records, and the actual data is not physically deleted, after the test, the data recovery is successful, but some problems have not been studied:
