连接表或联合表
Join Tables or union Tables
我正在尝试在同一个查询中加入两个 selection。
我尝试了联合，但我需要在同一行中应用寄存器。
我的 select 1 是：
SELECT
b.cod_articulo,
b.nom_articulo,
sum(a.cantidad) AS 'Cantidad',
sum(a.cantidad * b.conv_art_prec) AS 'Total Peso',
b.cod_uni_pesoart AS 'Unidad'
FROM

LEFT OUTER JOIN
ct_articulos b
ON
a.cod_articulo=b.cod_articulo
WHERE
b.cod_articulo IN ('40101','411','4112','4134','4135','4201','433','434','446','451','467','473','480','501','540','551','5510','562','5625','58201','635','5613')
AND YEAR(a.fec_doc)='2021'
AND MONTH(a.fec_doc)='05'
GROUP BY b.cod_articulo, b.nom_articulo, b.cod_uni_pesoart
select 的结果是：
