附带一个java类，可以把mysql的出错代码翻译成对应的出错信息：
import java.util.*;
public class MyErrorContext
{
public static class MyError
{
int errno;
String szErrorDesc;
public MyError(int errno, String errorDesc)
{
this.errno = errno;
this.szErrorDesc = errorDesc;
}
public int getErrorNo()
{
return errno;
}
public String getErrorDesc()
{
return szErrorDesc;
}
}
