Solution:
To begin with you can't do this:
having rid!=MAX(rid)
The Having clause can just hold things which are attributes of the aggregate groups.
Moreover, 1, 2, 3 is not valid in GROUP BY in SQL Server - I think that's just valid in ORDER BY.
Can you interpret why this isn't what you are search for:
select
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound,
MAX(qvalues.rid)
from batchinfo join qvalues on batchinfo.rowid=qvalues.rowid
where LEN(datapath)>4
group by LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound
Well, as it was expressed prior, you can't GROUP by literals, I think that you are confused because you can ORDER by 1, 2, 3. at the time you employ functions as your columns, you require to GROUP by the similar expression. Yet, the HAVING clause is wrong, you can just exercise what is in the agreggations. In this instance, your query must be like this:
SELECT
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound,
MAX(qvalues.rid) MaxRid
FROM batchinfo join qvalues
ON batchinfo.rowid=qvalues.rowid
WHERE LEN(datapath)>4
GROUP BY
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1),
qvalues.name,
qvalues.compound
You can't group by literals, just columns.
You are perhaps searching for something like th
select
LEFT(SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000), PATINDEX('%[^0-9]%', SUBSTRING(batchinfo.datapath, PATINDEX('%[0-9][0-9][0-9]%', batchinfo.datapath), 8000))-1) as pathinfo,
qvalues.name,
qvalues.compound,
qvalues.rid
from batchinfo join qvalues on batchinfo.rowid=qvalues.rowid
where LEN(datapath)>4
group by pathinfo, qvalues.name, qvalues.compound
having rid!=MAX(rid)
Firstly, you have to give that first expression a column name with as. Then you have to fix the names of the columns in the group by expression.
