我有一个班级People_val。我在另一个类中列出了这个类。现在我在这个列表上做一个foreach,对于我称之为ToSQL()函数的每个项目,它给我一个插入查询。列表计数超过50,000条记录。第9774号查询未完全形成。 9771 INSERT INTO CONVERSION_PEOPLE_VALIDATION VALUES(16413,'Jnto','Johnson',因此,命令未执行且事务被回滚。 我应该怎么做以获得foreach中的完整字符串。
public class People_Val
{
public int MEMBERS_ID;
public string PFirstName;
public string PLastName;
public DateTime? BIRTH_DATE;
public string RELATIONSHP;
public string ToSQL()
{
return string.Format("INSERT INTO CONVERSION_PEOPLE_VALIDATION VALUES ({0},'{1}','{2}','{3}', TO_CHAR('{4}', 'DD-MON-YYYY'))",
MEMBERS_ID, PFirstName.Replace("'","\""), PLastName.Replace("'","\""), RELATIONSHP, BIRTH_DATE);
}
}
public void insertPeopleValTrans(List<People_Val> _lstPeoplevals)
{
int count=0;
TextWriter tw = new StreamWriter(@"C:\PeopleVal.txt");
using (OracleConnection conn = new OracleConnection(connectionStr)) {
conn.Open();
OracleTransaction trans;
trans = conn.BeginTransaction();
try {
foreach (People_Val peopleVal in _lstPeoplevals) {
OracleCommand cmd = new OracleCommand(peopleVal.ToSQL(), conn, trans);
cmd.ExecuteNonQuery();
count++;
if (count % 500 == 0) {
Console.WriteLine("saving " + count.ToString() + " Records");
}
tw.WriteLine(count.ToString()+" "+ peopleVal.ToSQL());
}
trans.Commit();
tw.Close();
} catch (Exception ex) {
Console.WriteLine(ex.Message);
trans.Rollback();
}
conn.Close();
}
}

您可能在某些数据中包含撇号,导致查询失败。
尝试参数化输入...看起来RELATIONSHIP字段是原始数据,可能是问题所在。看看http://www.devart.com/dotconnect/oracle/articles/parameters.html我很确定这会让你感到厌烦。
粘贴在第9771行让我们看看......

是否真的有必要让所有50000条记录一起成功或失败?否则跳过交易或至少提交一点,可能是......
if (count % 500 == 0)
{
trans.Commit();
Console.WriteLine("saving " + count.ToString() + " Records");
trans = conn.BeginTransaction();
}
我同意previos评论,这将是使用Entity Framework Code First的最小努力。
