구문

‘선언
Public Sub New ( _
    commandText As String, _
    connection As SqlCeConnection, _
    transaction As SqlCeTransaction _
)
‘사용 방법
Dim commandText As String
Dim connection As SqlCeConnection
Dim transaction As SqlCeTransaction

Dim instance As New SqlCeCommand(commandText, _
    connection, transaction)

public SqlCeCommand(
    string commandText,
    SqlCeConnection connection,
    SqlCeTransaction transaction
)

public:

    String^ commandText, 
    SqlCeConnection^ connection, 
    SqlCeTransaction^ transaction
)

new : 
        commandText:string * 
        connection:SqlCeConnection * 
        transaction:SqlCeTransaction -> SqlCeCommand

매개 변수

• commandText
  유형: System.String
  쿼리 텍스트입니다.

• connection
  유형: System.Data.SqlServerCe.SqlCeConnection
  데이터 원본에 대한 연결을 나타내는 SqlCeConnection입니다.

• transaction
  유형: System.Data.SqlServerCe.SqlCeTransaction
  SqlCeCommand 가 실행되는 트랜잭션입니다.

주의

다음 표에서는 SqlCeCommand 인스턴스의 초기 속성 값을 보여 줍니다.

관련 속성을 설정하여 이러한 모든 매개 변수의 값을 변경할 수 있습니다.

예

다음 예제에서는 SqlCeCommand를 만들고 그 속성의 일부를 설정합니다.

        Dim cmdText As String = "INSERT INTO FactSalesQuota " & _
                "(EmployeeKey, TimeKey, SalesAmountQuota) " & _
                "VALUES (2, 1158, 150000.00)"

        Dim conn As New SqlCeConnection("Data Source = AdventureWorks.sdf;")
        conn.Open()

        ' Start a local transaction; SQL Mobile supports the following 
        ' isolation levels: ReadCommitted, RepeatableRead, Serializable
        '
        Dim tx As SqlCeTransaction = conn.BeginTransaction(IsolationLevel.ReadCommitted)

        ' By default, commands run in auto-commit mode; 
        '
        Dim cmd As New SqlCeCommand(cmdText, conn, tx)

        Try
            cmd.ExecuteNonQuery()

            ' Commit the changes to disk if everything above succeeded;
            ' Use Deferred mode for optimal performance; the changes will 
            ' be flashed to disk within the timespan specified in the 
            ' ConnectionString 'FLUSH INTERVAL' property; 
            '
            tx.Commit(CommitMode.Deferred)

            ' Alternatively, you could use:
            ' tx.Commit(CommitMode.Immediate);
            '

            '

        Finally
            conn.Close()
        End Try
