Action 在做分页


这是什么原因 概念没有问题

把java文件发一下

重命名下扩展名

jishuang

加一个system.out输出看看输出的是什么
        public static Table QueryByPage(Integer limit,Integer offset){
                String KSqlWord="SELECT id,sxr.innerid,sxr.name,sxr.type,sxr.length,sxr.startLat,sxr.startLng,sxr.startStakeNum,sxr.endStakeNum,sxr.endLat,sxr.endLng,sxr.tax,sxr.taxRate,sxr.sectionOwnerId,sxr.chargeType,sxr.tollRoads,sxr.builtTime,sxr.startTime,sxr.endTime FROM sx_roadinfo sxr";
                System.out.println("KSqlWord:"+KSqlWord);
                                Table table = KSQL.select(KSqlWord, null, "/sx/roadinfo/data", null);
                                     table.getProperties().put(Table.PROP_NAME_ROWID, "sxr");
                                     
                                     Table countTable = KSQL.select("Select Count(a) as cnt From sx_roadinfo a ", null, "/sx/roadinfo/data", null);
                                     BigDecimal num = countTable.iterator().next().getDecimal("cnt");
                                     table.getProperties().put(Table.PROP_DB_COUNT, num);
                return table;
        }

输出:SELECT id,sxr.innerid,sxr.name

,sxr.type,sxr.length,sxr.startLat,sxr.startLng,sxr.startStakeNum,sxr.endStakeNum,sxr.endLat,sxr.endLng,sxr.tax,sxr.taxRate,sxr.sectionOwnerId,sxr.chargeType,sxr.tollRoads,sxr.builtTime,sxr.startTime,sxr.endTime FROM sx_roadinfo sxr
在Sql server中执行没有问题

jishuang

String KSqlWord="SELECT id,sxr.innerid,sxr.name,sxr.type,sxr.length,sxr.startLat,sxr.startLng,sxr.startStakeNum,sxr.endStakeNum,sxr.endLat,sxr.endLng,sxr.tax,sxr.taxRate,sxr.sectionOwnerId,sxr.chargeType,sxr.tollRoads,sxr.builtTime,sxr.startTime,sxr.endTime FROM sx_roadinfo sxr";
改为

String KSqlWord="SELECT sxr.id,sxr.innerid,sxr.name,sxr.type,sxr.length,sxr.startLat,sxr.startLng,sxr.startStakeNum,sxr.endStakeNum,sxr.endLat,sxr.endLng,sxr.tax,sxr.taxRate,sxr.sectionOwnerId,sxr.chargeType,sxr.tollRoads,sxr.builtTime,sxr.startTime,sxr.endTime FROM sx_roadinfo sxr";
这样看看

sxr.id找不到对应的关系映射

jishuang

你的概念中有id这个关系吗？没有就去掉
