EnumCandidateKeys 方法
枚举数据库中可由外键引用的所有候选主键的列表。
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 EnumCandidateKeys As DataTable
用法
Dim instance As Database
Dim returnValue As DataTable
returnValue = instance.EnumCandidateKeys()
public DataTable EnumCandidateKeys()
public:
DataTable^ EnumCandidateKeys()
member EnumCandidateKeys : unit -> DataTable
public function EnumCandidateKeys() : DataTable
示例
The example runs a Server object enumeration method, but extracting the information from the DataTable object is the same for database object 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]
}
}
