[英]ORA-00907: missing right parenthesis - only comes up when I add a where statement (
I am using a string to access a code that will then access an ORACLE data, I use this code a lot, but for some reason it is not working now.我正在使用一个字符串来访问一个代码,然后该代码将访问一个 ORACLE 数据,我经常使用这个代码,但由于某种原因它现在不起作用。 The code below works fine when I don't include a where statement, but gives the above error when I do.当我不包含 where 语句时,下面的代码可以正常工作,但是当我这样做时会出现上述错误。 I have looked at other examples of this error, but can not find any that match what I am doing.我查看了此错误的其他示例,但找不到任何与我正在做的事情相匹配的示例。 Any help would be appreciated.任何帮助,将不胜感激。 Start year is the number 2010起始年份是数字 2010
select * from(
select
count(distinct(fileid)) as cyic,
to_number(substr(cym, 1, 4)) as cym,
from group.data
group by fileid, cym
where to_number(substr(cym, 1, 4)) >= :start_yr
)
The problem is that the WHERE
clause must come before the GROUP BY
clause.问题是WHERE
子句必须在GROUP BY
子句之前。 If you need to check something after the grouping, then you use HAVING
after the GROUP BY
.如果您需要在分组后检查某些内容,则在GROUP BY
之后使用HAVING
。
