问答 自定义sql查询某字段的sum
发布于 2789天前 作者 qq_a2022917 2099 次浏览 复制 上一个帖子 下一个帖子
标签: nutzwk 
Sql sql = Sqls.create("SELECT IFNULL(SUM(money),0) investTotal " + 
								" FROM ql_project_shareholder " + 
								" WHERE projectId = @projectId ");
		sql.setParam("projectId", projectId);
		Map map = this.getMap(sql);
		Object investTotal = map.get("investTotal");
		return (double)investTotal;

上边的是写的代码,下边的是报的异常.

 For example:> "SELECT IFNULL(SUM(money),0) investTotal  FROM ql_project_shareholder  WHERE projectId = 9"

把这个getMap方法的代码贴一下

BaseServiceImpl.getMap(BaseServiceImpl.java:508)

/**
     * 自定义sql获取map key-value
     *
     * @param sql
     * @return
     */
    public Map getMap(Sql sql) {
        sql.setCallback(new SqlCallback() {
            @Override
            public Object invoke(Connection conn, ResultSet rs, Sql sql)
                    throws SQLException {
                Map<String, String> map = new HashMap<>();
                while (rs.next()) {
                    map.put(Strings.sNull(rs.getString(1)), Strings.sNull(rs.getString(2)));
                }
                return map;
            }
        });
        this.dao().execute(sql);
        return sql.getObject(Map.class);
    }

@wendal

这个getMap不是用在这种场景的

你应该用 

Sql sql = Sqls.fetchInt(".........");
sql.setParam(.....);
dao.execute(sql);
int re = sql.getInt();

@wendal
那应该拿什么接收呢?兽总

完美解决!
谢谢兽总!
