直接将DataTable存入oracle数据库中（转）

Posted 2020-11-02 gisoracle

注意

    1:传入的DataTable的列必须和数据库中表列必须一致，否则数据会默认往前几列存

    2:sql语句只要是对要插入的表的一个查询，目的是为了确定表名

   3:取得连接字符串的方法为GetOracleConnection()，需要自己添加

public static bool insertValueWithDt(DataTable dataTable, string sql)

        {

            String ConnStr = GetOracleConnection();

            using (OracleConnection conn = new OracleConnection(ConnStr))

            {

                try

                {

                    OracleCommand cmd = new OracleCommand(sql,conn);

                    OracleDataAdapter adapter = new OracleDataAdapter(cmd);

                    OracleCommandBuilder cb = new OracleCommandBuilder(adapter);

                    DataTable dsNew = new DataTable();

                    int count = adapter.Fill(dsNew);

                    for (int i = 0; i < dataTable.Rows.Count; i++)

                    {

                        DataRow dr = dsNew.NewRow();

                        for (int j = 0; j < dataTable.Columns.Count; j++)

                        {

                            dr[dsNew.Columns[j].ColumnName] = dataTable.Rows[i][j];

                        }

                        dsNew.Rows.Add(dr);

                    }

                    count = adapter.Update(dsNew);

                    adapter.UpdateBatchSize = 200;

                    //adapter.Update(dataTable);

                    return true;

                }

                catch (Exception e)

                {

                    WriteLog writeLog = new WriteLog();

                    writeLog.WriteLogs(e.ToString());

                    return false;

                }

            }

        }
