ORA-01000:超出開啟遊標的最大數 的解決辦法(C#)

C#包裝了一個數據庫操作類,提供一個批量執行sql的函式,執行中遇到【ORA-01000:超出開啟遊標的最大數 的解決辦法】的錯誤。

檢視MSDN的ADODB.Connection的函式Execute說明,發現是呼叫時一個引數的問題。下面是我包裝的函式:

public bool ExecuteSql(string[] strSqlArray)
        {
            try
            {
                m_cn.BeginTrans();
                for (int i = 0; i < strSqlArray.Length; i++ )
                {
                    object objAffected;
                    m_cn.Execute(strSqlArray[i], out objAffected, 0); //引數【0】搗的鬼
                }
                m_cn.CommitTrans();
                return true;
            }
            catch (System.Exception e)
            {
                MsgBoxCtrl.MsgBoxException(e.Message, "CDatabase.ExecuteSql");
                if (m_cn.State == (int)ConnectionState.Open)
                {
                    try
                    {
                        m_cn.RollbackTrans();
                    }
                    catch (System.Exception e1)
                    {
                        MsgBoxCtrl.MsgBoxException(e1.Message, "CDatabase.ExecuteSql");
                    }
                }
                return false;
            }
        }

將上面的Execute呼叫改一下就Ok了

m_cn.Execute(strSql, out objAffected, (int)ADODB.ExecuteOptionEnum.adExecuteNoRecords);

下面是MSDN的說明:

Using the Execute method on a Connection Object (ADO) object executes whatever query you pass to the method in the CommandText argument on the specified connection. If the CommandText argument specifies a row-returning query, any results that the execution generates are stored in a new 

Recordsetobject. If the command is not intended to return results (for example, an SQL UPDATE query) the provider returns Nothing as long as the option adExecuteNoRecords is specified; otherwise Execute returns a closed Recordset.
