Question

这是连接2个表的查询，但我在JOIN附近收到错误消息

select CHKNBR, pidamt, copied_from_batdat, BATDAT, SEQNBR from UMCDTL 
where copied_from_batdat between '10/11/2013' and '11/4/2013'
and batseq between '001' and '100' and SEQNBR between '01' and '100'
join
UMCFIL on BATDAT=SEQNBR and seqnbr=batadat

输出需要显示

Original Claim Number  
Original Paid Amount
Original Check Number

Answer 1

如果您想使用＆＃39;加入＆＃39;特别是，它需要在你的＆＃39; FROM＆＃39;子句。

Select...
From
   table1 JOIN table2 ON Table1.key = Table2.key
Where...

如果您想使用＆＃39; WHERE＆＃39;加入表的子句，然后将关键字段关联在那里：

Select...
FROM
   table1, table2
WHERE
   table1.key = table2.key
   ...

Answer 2

尝试类似：

SELECT CHKNBR, pidamt, copied_from_batdat, BATDAT, SEQNBR 
FROM UMCDTL JOIN UMCFIL ON BATDAT=SEQNBR AND seqnbr=batadat
WHERE copied_from_batdat between '10/11/2013' AND '11/4/2013' 
AND batseq BETWEEN 1 AND 100 
AND SEQNBR BETWEEN 1 AND 100

加入查询以显示2个表中的信息
