通过T-SQL 创建数据库时,不会强制实施 Azure 策略。 若要在使用 T-SQL 创建数据库时指定数据驻留,请使用 LOCAL 或 ZONE 作为 CREATE DATABASE 语句中 BACKUP_STORAGE_REDUNDANCY 参数的输入。 其他资源 活动 加入AI 技能节挑战 4月8日 23时 - 5月28日 15时 ...
PAGE compression minimizes the data redundancy in columns in one or more rows on a given page. It uses a proprietary implementation of the LZ78 (Lempel-Ziv) algorithm, storing the redundant data only once on the page and then referencing it from the multiple columns. Note that when you use...
Database mirroring in SQL Server allows you to keep a copy, or mirror, of a SQL Server 2005 database on a standby server. Mirroring ensures that two separate copies of the data exist at all times, providing high availability and complete data redundancy. The .NET Data Provider for SQL ...

In many cases database mirroring can provide the same kind of data redundancy as log shipping with higher availability and automatic failover. However, if your application relies on multiple databases on one server, log shipping may be an equally valid approach (see "Multi-Database Considerations...

When binary checksums are used, 32-bit redundancy check (CRC) occurs on a column-by-column basis rather than a CRC on the physical row on the data page. This allows the columns with the table to be in any order physically on the data page, but still compute to the same CRC for the...
