SQL查询总结列

Question

进出口新为sql目前使用一本书来学习它，我有表

CREATE TABLE EMPLE (

INSERT INTO EMPLE VALUES (1,'PEDRO PEREZ MORA');

INSERT INTO EMPLE VALUES (10,'LIDIETH JARA ECHANDI'); 
INSERT INTO EMPLE VALUES (11,'JOSE MORA QUIROS'); 
INSERT INTO EMPLE VALUES (12,'ROY PAZOS RODRIGUEZ'); 

最终的结果应该是这样的：

我有什么一个简单的选择语句

select e.codigo, e.nombre 
from mov e; 

我怎样才能使查询结果为打算在图像 谢谢

Answer 1

一个简单的LEFT JOIN与GROUP BY应该这样做;

SELECT e.codigo, e.nombre, 
    SUM(CASE WHEN m.tipo = 'I' THEN m.monto ELSE 0 END) ingresos, 
    SUM(CASE WHEN m.tipo = 'D' THEN m.monto ELSE 0 END) deducciones, 
    SUM(CASE WHEN m.tipo = 'I' THEN m.monto ELSE 0 END) - 
    SUM(CASE WHEN m.tipo = 'D' THEN m.monto ELSE 0 END) neto 
FROM emple e 
LEFT JOIN mov m 
    ON e.codigo = m.codigo 
GROUP BY e.codigo, e.nombre 
ORDER BY e.codigo, e.nombre 

的LEFT JOIN让我们收集了所有相应的“MOV” S每个“emple”，以及GROUP BY让我们来总结他们为每个codigo /农布雷组合。

An SQLfiddle to test with。

如果我理解你需要加入这两个表。

喜欢的东西...

Select e.*,m.* from emple e,mov m where e.codigo = m.codigo;
