我如何将此选项设置为 FbTransaction

write
nowait
rec_version
read_committed

在我的代码中执行插入/更新 sql 语句：

FbConnectionStringBuilder fbConnStr = new FbConnectionStringBuilder();

using (FbConnection fbConn = new FbConnection(fbConnStr))
{
   fbConn.Open();
   using (FbTransaction fbTran = fbConn.BeginTransaction())
   {
      using (FbCommand fbCmd = new FbCommand("insert into TEST values (1)", fbConn, fbTran)
      {
         fbCmd.CommandType = CommandType.Text;
         fbCmd.ExecuteNonQuery();
         fbCmd.Transaction.Commit();
      }
   }
   fbConn.Close();
}

你可以使用FbTransactionOptions：

FbTransaction transaction = Connection.BeginTransaction(
    FbTransactionOptions.ReadCommitted  |
    FbTransactionOptions.Write|
    FbTransactionOptions.RecVersion|
    FbTransactionOptions.NoWait |
    );

另请参阅IsolationLevel：

• IsolationLevel.ReadUncommitted
• IsolationLevel.ReadCommitted
• IsolationLevel.RepeatableRead
• IsolationLevel.Serializable

你可以这样做：

FbTransaction transaction = Connection.BeginTransaction( IsolationLevel.Serializable );
