【问题描述】：

我有以下两个表

表格1

PKey	number	amount	date
CN-897687	YHVY	299.99	11/21/22 3:32 PM
CN-646465	JWVF	271.05	10/21/22 4:34 AM
CN-475678	C96H	61.99	7/1/22 11:05 AM
CN-858673	QCVM	324.08	3/1/22 9:51 AM
CN-347468	RW44	165.02	5/9/22 8:49 AM
CN-079836	3XTY	371.34	11/27/22 8:48 PM

表 2

PKey	state	open_amt	date
CN-897687	issued	-299.99	11/21/22 3:32 PM
CN-897687	issued	-0.99	11/29/22 11:31 AM
CN-475678	issued	-61.99	7/1/22 11:05 AM
CN-858673	issued	-324.08	3/1/22 9:51 AM
CN-858673	cleared	0.00	11/17/22 12:32 AM
CN-858673	issued	-173.75	5/1/22 12:17 AM
CN-347468	issued	-165.02	5/9/22 8:49 AM
CN-079836	issued	-371.34	11/27/22 8:48 PM
CN-079836	issued	-21.84	12/1/22 10:53 AM
CN-646465	issued	-271.05	10/21/22 4:34 AM
CN-646465	issued	-22.95	11/4/22 9:42 AM
CN-646465	issued	-9.60	12/1/22 12:20 AM
CN-646465	cleared	0.00	12/2/22 12:34 AM

我正在使用下面的 sql 查询来获取如下输出

PKey	number	amount	date	state	open_amt
CN-897687	YHVY	299.99	11/21/22 3:32 PM	issued	-0.99
CN-646465	JWVF	271.05	10/21/22 4:34 AM	cleared	0.00
CN-475678	C96H	61.99	7/1/22 11:05 AM	issued	-61.99
CN-858673	QCVM	324.08	3/1/22 9:51 AM	cleared	0.00
CN-347468	RW44	165.02	5/9/22 8:49 AM	issued	-165.02
CN-079836	3XTY	371.34	11/27/22 8:48 PM	issued	-21.84

我想要输出如下

PKey	number	amount	date	state	open_amt
CN-897687	YHVY	299.99	11/21/22 3:32 PM	issued	-0.99
CN-475678	C96H	61.99	7/1/22 11:05 AM	issued	-61.99
CN-347468	RW44	165.02	5/9/22 8:49 AM	issued	-165.02
CN-079836	3XTY	371.34	11/27/22 8:48 PM	issued	-21.84

select distinct

t1.Pkey
t1.number,
t1.date,
t1.amount,
t2.open_amt,
t2.state

from 

        
(select *  from table 1
                            where PKey IN (
'CN-897687',
'CN-646465',
'CN-475678',
'CN-858673',
'CN-347468',
'CN-079836')
) t1
        
left join   (select *
                   from (select *, row_number () over (partition by Pkey order by date desc) rn
                            from table 2)
                                            where rn = 1
                                            -- and open_amt <> 0
                                           -- and state <> 'cleared'
) t2
                           
                                                on t1.Pkey = t2.Pkey

试图用不同的组合为 state <> 'cleared' 和 open_amt <> 0 设置过滤器，但没有得到所需的输出

【问题讨论】：

一般提示：当问一个包含大量示例数据的问题时，建议创建一个小提琴，这将使复制您的问题并尝试可能的解决方案变得容易得多。

【解决方案1】：

只需在子查询中添加过滤条件。

select *, row_number () over (partition by Pkey order by date desc) rn
                            from table 2 where open_amt >0
                                           and trim(lower(state)) <> 'cleared'

顺便说一句：我没有执行您的查询。
