Java 在计算字段中找不到数据

我对计算的行有问题，但y仍然不明白：

SQLException at ln 1381: No data found
java.sql.SQLException: No data found
   at sun.jdbc.odbc.JdbcOdbc.standardError(Unknown Source)
   at sun.jdbc.odbc.JdbcOdbc.SQLGetDataString(Unknown Source)
   at sun.jdbc.odbc.JdbcOdbcResultSet.getDataString(Unknown Source)
   at sun.jdbc.odbc.JdbcOdbcResultSet.getString(Unknown Source)
   at sun.jdbc.odbc.JdbcOdbcResultSet.getString(Unknown Source)
   at main.EngineDueList.LdgsDueList(EngineDueList.java:1263)
   at main.EngineDueList.createPDF(EngineDueList.java:93)
   at main.AircraftList.<init>(AircraftList.java:187)
   at Launch.main(Launch.java:13)

当我在access中执行请求时，我得到了一个很好的结果：

当我搜索关于这一行的信息时，这似乎并不奇怪：

此代码：

System.out.println(data.getMetaData().getColumnName(8)+" is a type : "+data.getMetaData().getColumnTypeName(8));

在控制台中编写此代码

RemainLdgs is a type : DOUBLE

我没有读取该字段两次（已验证）

为什么我不能读这个字段
