Question

我有一个查询，查询了三年（2016年，2017年和2018年）的结果，现在我需要包括第四年（2019年），我不知道该怎么做。

我尝试复制查询部分以更改年份，但出现很多错误。

SELECT MAX(qnt2016) as qnt2016, MAX(qnt2017) as qnt2017, MAX(qnt2018) as qnt2018, empresa FROM
(SELECT CASE WHEN COUNT(cliente) IS NULL THEN 0
        ELSE COUNT(cliente) END AS qnt2016,  0 as qnt2017, 0 as qnt2018, empresa, rep
        FROM
        (SELECT E026RAM.CODRAM tipo, E026RAM.DESRAM nome, E085HCL.CODCLI cliente, E085HCL.CODREP rep, E090REP.APEREP empresa

您需要在关闭子查询之前添加另一个UNION ALL，并将新字段添加到所有SELECT语句中

SELECT MAX(qnt2016) as qnt2016, MAX(qnt2017) as qnt2017, MAX(qnt2018) as qnt2018, MAX(qnt2019) as qnt2019, empresa FROM
               (SELECT CASE WHEN COUNT(cliente) IS NULL THEN 0
                ELSE COUNT(cliente) END AS qnt2016,  0 as qnt2017, 0 as qnt2018, 0 as qnt2019, empresa, rep
                                FROM
                ...
               union all

                SELECT 0 as qnt2016, 0 as qnt2017, , 0 as qnt2018, CASE WHEN COUNT(cliente) IS NULL THEN 0
                        ELSE COUNT(cliente) END AS qnt2019, empresa, rep
                FROM
                (SELECT
                E026RAM.CODRAM tipo, E026RAM.DESRAM nome, E085HCL.CODCLI cliente, E085HCL.CODREP rep, E090REP.APEREP empresa
                FROM
               E085HCL, E090REP, E085CLI, E026RAM, E070EMP, E007UFS
                WHERE
                ((E085CLI.SITCLI = 'A')) AND
                ((E026RAM.CODRAM in (1,2,3))) AND
                (((E085CLI.DATCAD >= '2000-01-01') AND (E085CLI.DATCAD <= '2019-12-31'))) AND
                ((E085HCL.CODEMP = 1)) AND
                ((E085CLI.SIGUFS = E007UFS.SIGUFS) AND 
                 (E085HCL.CODREP = E090REP.CODREP) AND
                (E085CLI.CODRAM = E026RAM.CODRAM) AND 
                (E085HCL.CODCLI = E085CLI.CODCLI) AND 
                (E085HCL.CODEMP = E070EMP.CODEMP))) C2018
                where tipo not in (10, 15)
                GROUP BY rep, empresa, rep) select2
                GROUP BY empresa, rep
                order by rep

我回答了您需要向查询添加什么数据，但是正如注释中所述，这是进行此查询的一种糟糕方法。了解pivoting，我认为是重新处理此查询的正确方法。
