Question

我正在从两个表中进行查询。表是“输入”而另一个是“输出”。 OUTPUT表中的愿望清单在出货时带有加号（“ - ”更少）。列出正面和负面的值时，这会变得更容易。

查看我的查询： http://sqlfiddle.com/#!2/93dbcb/1

(SELECT nome, data, valor FROM `financ_receita` WHERE data BETWEEN ('2012-12-01') AND ('2013-12-23'))
    UNION ALL
(SELECT nome, data, valor FROM `financ_despesa` WHERE data BETWEEN ('2012-12-01') AND ('2013-12-23')) ORDER BY data ASC

financ_receita =输入。

financ_despesa = out。

Answer 1

是吗？

select nome,data,if(valor<0,concat(valor),concat('+',valor)) as valor from 
(
 (
  SELECT nome, data, valor FROM `financ_receita` 
  WHERE data BETWEEN ('2012-12-01') AND ('2013-12-23')
 )
 UNION ALL
 (
  SELECT nome, data, valor*-1 FROM `financ_despesa`
  WHERE data BETWEEN ('2012-12-01') AND ('2013-12-23')
 ) 
 ORDER BY data ASC
) as myTable where valor != 0
