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.

示例

VB

'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server

'Reference the AdventureWorks2012 database.
Dim db As Database
db = srv.Databases("AdventureWorks2012")

'Shrink the database without truncating the log.
db.Shrink(20, ShrinkMethod.NoTruncate)

'Truncate the log.
db.TruncateLog()

PowerShell

$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$db = New-Object Microsoft.SqlServer.Management.Smo.Database
$db = $srv.Databases.Item("AdventureWorks2012")

$db.Shrink(20, [Microsoft.SqlServer.Management.Smo.ShrinkMethod]'NoTruncate')

$db.TruncateLog()
