这是我第一次进入MySQL世界。但是，我收到了这个错误。
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' '9/30/2012 12:00:00 AM', '10/1/2012 12:00:00 AM', '9/30/2012 12:00:00 AM', '', ' at line 1
命令文本很长，所以很抱歉。另外，我知道关于SQL注入以及如何预防它;但是，这个程序仅供内部使用，不会冒这个风险。

答案 2 :(得分：0)
我会进一步采用你自己的解决方案......你正在为每条记录重建命令，字符串和参数。我会按以下方式调整......
（假设您至少有一行，并且您已对此进行了测试）
DataRow r = dt.Rows[0];
cmd = ...
cmd.CommandText = ... (as you already have parameterized).
定义参数ONCE（就像你一样）。
cmd.Parameters.Add("@ControlNumber", r["ControlNumber"]);
cmd.Parameters.Add("@Jur_Id", r["Jur_ID"]);
cmd.Parameters.Add("@Jur_Status", r["Jur_Status"]);
...
现在，您已经完成了所有构建和参数的命令...现在，您可以遍历每一行并只更新每行的参数值（因此不必继续重建参数和所有创造每次的开销）......
foreach (DataRow r2 in dt.Rows)
{
// just keep the parameters in the same sequence as you have when creating
// you just update the value that will be applied when executed.
cmd.Parameters[0].Value = r2["ControlNumber"]);
cmd.Parameters[1].Value = r2["Jur_ID"]);
cmd.Parameters[2].Value = r2["Jur_Status"]);
...
cmd.ExecuteNonQuery();
}
