在vs2017中使用Oralcebulkcopy向oralce11g數據庫批量插入數據

 

vs2017運行於64位win10環境下。

一.下載並安裝ODAC 11.2 Release 5 and Oracle Developer Tools for Visual Studio (11.2.0.3.20)

下載地址爲：https://www.oracle.com/technetwork/topics/dotnet/utilsoft-086879.html。

下載後得到ODTwithODAC1120320_32bit.zip   文件，大小爲229 MB，壓縮並安裝。

二.在項目中引用Oracle.DataAccess.dll。

三.代碼

public static void BulkToDB(DataTable dt, string targetTable)
        {
            string err = "大批量插入時產生錯誤";
            OracleConnection conn = new OracleConnection(conStr);
            //System.Data.OracleClient.OracleConnection conn = new OracleConnection(conStr);
            if (conn.State != ConnectionState.Open)
            { conn.Open(); }
            OracleBulkCopy bulkCopy = new OracleBulkCopy(conn, OracleBulkCopyOptions.Default);
            bulkCopy.BatchSize = 100000;
            bulkCopy.BulkCopyTimeout = 260;
            bulkCopy.DestinationTableName = targetTable;
 
            try
            {
                if (conn.State != ConnectionState.Open)
                {
                    conn.Open();
                }
                // conn.Open();
                if (dt != null && dt.Rows.Count != 0)
                {
                    bulkCopy.WriteToServer(dt);
 
                }
            }
            catch (Exception ex)
            {
                Log.WriteLog(err, ex);
            }
            finally
            {
                conn.Close();
                if (bulkCopy != null)
                    bulkCopy.Close();
            }
 
        }
