Assembly: Microsoft.SqlServer.Smo (in Microsoft.SqlServer.Smo.dll)
- Type: System.Int32
Return ValueType: System.Data.DataTable
A DataTable object value that contains a list of locks held on the database and information about the type and location of the locks. The table describes the different columns of the returned DataTable.
The system process ID value of the process that is holding a lock on a database resource.
The description of the type of lock. See the syslockinfo table for a description of different lock types.
The name of the database on which the lock is held.
The name of the table on which the lock is held. This field contains a value only if the lock is held on a table.
The name of the index on which the lock is held. This field contains a value only if the lock is held on an index.
The status of the lock, which can be one of the following:
1 = Granted.

The example runs a Server object enumeration method, but extracting the information from the DataTable object is the same for database enumeration methods.
'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
