问答 nut自定义sql打印问题
发布于 2461天前 作者 shudaixiong001 2702 次浏览 复制 上一个帖子 下一个帖子

最近用nutz做postgresql的后台框架，执行复杂的sql，但是sql在执行execute后不再执行，控制台不报错；手动将@参数值补全，放到pg中可以执行；
请问，如何可以打印最终提交到数据库的带参数值的sql？如果不能打印，请问如何让控制台报出sql错误？

上代码

public List<Map> searchCounties(@Param("geometry")String geometry,@Param("table")String table,@Param("type")String type,@Param("areal")String areal,@Param("areah")String areah){
		System.out.println("*************");
		String sqlstr="with a as ("
				+"select st_transform(st_geomfromtext(@geometry,4326),32650) shape" 
				+")"
				+"select t.name,st_area(st_transform(t.shape,32650)) tarea,st_astext(st_transform(t.shape,4326)) tshape  from gisdb.$table t,a where st_intersects(t.shape,a.shape) and t.name like '%@type%' and st_area(st_transform(t.shape,32650)) between @areal and @areah"
				+" ";
		//Sql sql=Sqls.queryRecord("select st_area(st_transform(t.shape,32650)),* from gisdb.urbanplan t where ST_Intersects(t.shape,st_transform(st_geomfromtext(@geometry,4326),4490)) ");
		Sql sql=Sqls.queryRecord(sqlstr);
		List<Map> lists=new ArrayList<>();
		sql.vars().set("table",table);
		sql.params().set("geometry", geometry);
		sql.params().set("areal", areal);
		sql.params().set("areah", areah);

		dao.execute(sql);
		List<Record> list=sql.getList(Record.class);
		Map listMap=new HashMap<>();
		listMap.put("type",table);
		listMap.put("data",list);
		lists.add(listMap);
		return lists;

	}

execute之前加一句:

sql.forceExecQuery();
dao.execute(sql);

另外，日志里面没有打印sql吗？日志没配好？

还是原来的错误，请问可以打印最终提交到数据库的带参数值的sql吗，这个应该是sql错误

日志里面就有sql啊，贴日志看看

因为是预处理sql，不存在"真正执行的sql”，只有预处理sql加参数矩阵

设置参数后，可以打印sql.toString()，是示意sql语句

好的，麻烦版主了，我再调试一下吧，入门有点着急了

贴日志有多难？

好吧，贴一个，不知道是不是特简单的错误，本想自己看看解决的

type参数没赋值，而且在sql里面定义得不对

t.name like @type

其他字段的类型啥？geo？

测试通过了，是因为between and 的值带引号的数字在pg中可以运行，在程序里面判断为类型错误
double precision >= character varying
