SqlCeParameter 建構函式 (String, SqlDbType, Int32, ParameterDirection, Boolean, Byte, Byte, String, DataRowVersion, Object)

  • 發行項

使用參數名稱、資料類型、長度、參數方向和其他屬性，初始化 SqlCeParameter 類別的新執行個體。SQL Server Compact 只支援輸入參數。

參數

  • isNullable
    型別：System.Boolean
    如果欄位值可以是 null，則為 true，否則為 false。
  • precision
    型別：System.Byte
    Value 所解析的小數點左右側的位數總數。
  • sourceColumn
    型別：System.String
    來源資料行的名稱。
