EnumLocks 方法 (Int32)
为指定的系统进程 ID 枚举数据库上持有的当前锁的列表。
命名空间: Microsoft.SqlServer.Management.Smo
程序集: Microsoft.SqlServer.Smo(在 Microsoft.SqlServer.Smo.dll 中)
语法
声明
Public Function EnumLocks ( _
processId As Integer _
) As DataTable
用法
Dim instance As Database
Dim processId As Integer
Dim returnValue As DataTable
returnValue = instance.EnumLocks(processId)
public DataTable EnumLocks(
int processId
)
public:
DataTable^ EnumLocks(
int processId
)
member EnumLocks :
processId:int -> DataTable
public function EnumLocks(
processId : int
) : DataTable
参数
- processId
类型:System. . :: . .Int32
一个 Int32 值,该值指定唯一标识进程的进程 ID 值。
返回值
类型:System.Data. . :: . .DataTable
一个 DataTable 对象值,该值包含数据库上持有的锁列表以及有关这些锁的类型和位置的信息。该表描述所返回的 DataTable 的不同列。
示例
The example runs a Server object enumeration method, but extracting the information from the DataTable object is the same for database enumeration methods.
VB
'Connect to the local, default instance of SQL Server.
Dim srv As Server
srv = New Server
'Call the EnumCollations method and return collation information to DataTable variable.
Dim d As DataTable
'Select the returned data into an array of DataRow.
d = srv.EnumCollations
'Iterate through the rows and display collation details for the instance of SQL Server.
Dim r As DataRow
Dim c As DataColumn
For Each r In d.Rows
Console.WriteLine("============================================")
For Each c In r.Table.Columns
Console.WriteLine(c.ColumnName + " = " + r(c).ToString)
Next
Next
PowerShell
$srv = new-Object Microsoft.SqlServer.Management.Smo.Server("(local)")
$d = new-object System.Data.Datatable
$d = $srv.EnumCollations
Foreach ($r in $d.Rows)
{
Write-Host "============================================"
Foreach ($c in $d.Columns)
{
Write-Host $c.ColumnName "=" $r[$c]
}
}
