Truncating the log means that records of completed transactions that make up the inactive part of the log are deleted. The remaining incomplete transactions in the active part of the log are not deleted. The log is usually truncated after a backup.

只有 Microsoft .NET Framework 2.0 版支援此命名空間、類別或成員。

範例

'Shrink the database without truncating the log.
