SQL error: ROW_NUMBER() OVER (PARTITION
In SQLite, you can typically use rowid
:
select s.*
from stops s
where s.rowid = (select min(s2.rowid)
from stops s2
where s2.stop_id = s.stop_id and s2.stop_name = s.stop_name
);
I'm not sure if this is what you really need. But this seems to be what you want to do with row_number()
. If this doesn't hit the spot, then ask another question with sample data and desired results.
Syntax error in SQL code being used in R, no row_number function found
It looks like you are missing a comma after the *
. The following works as expected:
DBI::dbGetQuery(con, '
SELECT *,
row_number() over(partition by cyl) AS rn
FROM sql_mtcars
')
Note the addition of a comma after the *
and before the row_number
.
