问题：其中：表里zcmc字段为字符型，在oracle +PLSQL Developer 查询得出数据为：5 （如果改为05，就能正确取出数据）
1。如果zcmc字段为一个位数值时，就发出错误（如下异常），如果用rs.getInt(1)取值就得出 为：0
2。如果zcmc字段为两位数值或两个字符串以上时，得出正确的数据
javabean代码：
public String filemc()
{
Connection con = null;
PreparedStatement ps = null;
ResultSet rs=null;
String mc="";
try
{
String strQuery="select zcmc from t_czzc_file where zcid=001";
System.out.println(strQuery);
con=ds.getConnection();
ps = con.prepareStatement(strQuery);
rs=ps.executeQuery();
if(rs.next())
{
mc=rs.String("zcmc");
System.out.println(mc);
}
}
catch(SQLException e){
e.printStackTrace();
}
finally
{
if (rs != null) try {rs.close();}
catch (SQLException ignore) {}
if (ps != null) try {ps.close();}
catch (SQLException ignore) {}
if (con != null) try {con.close();}
catch (SQLException ignore) {}
}
return mc;
}
错误：
