increments of 64KB. This corresponds well to how the data is organized in memory and in the NT File System (NTFS) format partition. However, as mentioned earlier, SQL Server can store pages from different objects in a single region to maximize storage efficiency. 2. PageAll data and metadata for the SQL servei* 2008 database are stored in the page. Unlike zones,

Dealing with SQL with transactions Statement writing stored procedures can be used to package and standardize your data access, and stored procedures are actually stored in the database. Stored Procedures Can be either with parameters or without parameters, either by database programs or manually by SQL Server Query Analyze

compression, SQL Server 2008 uses the following three methods to save storage space:Reduces the metadata overhead associated with the record. This metadata contains information about the column, column length, and offset. In some cases, the metadata overhead may be greater than the old storage format.It uses variable-length storage formats for numeric types (suc

When this transaction is not finished, another thing is accessing the same data, and the first transaction two reads from the first transaction two reads, because of the modification of the second transaction, the data may be different. This occurs when the data that is read two times within a transaction is different, so it is called non-repeatable read. Phantom reading : a phenomenon that occurs whe

When you create a table, you must assign a data type to each column in the table. This section describes some of the most common data types in SQL Server. Even if you create a custom data type, it must be based on a standard SQL Server data type. For example, you can use the following syntax to create a custom data typ
