Hello,
I have a query in sqlalchemy like below where I lookup contract# in mssql.
How do I enforce the varchar instead of nvarchar? I tried converting my
field to "str(mycurrent)" but that didn't do anything. Is there some other
spot to force VARCHAR to be sent?
You can find that the query that uses NVARCHAR does an index scan has
30,909 logical reads on the dbo.P table. It also uses 890 ms of CPU and
has a total elapsed time of 938 ms.
The query that uses VARCHAR does an index seek and has 7 logical reads on
the dbo.P table. It uses 0 ms of CPU and has a total elapsed time of 11 ms.
p=*session.execute*("select PZ.p_id,PZ.pimage_num from dbo.P with(nolock)
inner join dbo.PZ PZ with(nolock) on PZ.p_id = p.p_id inner join dbo.D D
with(nolock) on D.p_id = p.p_id AND D.pimage_num=PZ.pimage_num where
p.current=:mycurrent and D.srtype_id
=5",params={'mycurrent':str(mycurrent)}).fetchall()
