Like I have to take source,ID and destination from sql table but they are present in two different table, so I have tried with
dom_id=[1,10,19,31,37,42,48,57,63,64,65]
for i in range(len(dom_id)):
cursor.execute("SELECT xval, yval from table1 WHERE DOMID=?",dom_id[i])
source=""
for row in cursor.fetchall():
source=float(row[0]),float(row[1])
source=','.join(map(str, source))
cursor.execute("select t1.id as pid,pxval,pyval from table2")
ID=[]
destination=""
for row_d in cursor.fetchall():
ID.append(row_d[0])
destination = float(row_d[1]),float(row_d[2])
destination = ','.join(map(str, destination))
Right now I'm using for-loop to extract source and other for-loop to extract ID
and destination
I tried with
cursor.execute(("SELECT xval, yval from table1 WHERE DOMID=?",dom_id[i]);("select t1.id as pid,pxval,pyval from table2 t1 left join (select * from table3 where clubid=?) t2 on t1.id=t2.pid where t1.cityid in (SELECT cityid FROM table1 WHERE domid = ? group by cityid) and t1.pxval>0 and t2.distance is null order by pid",(dom_id[i],dom_id[i])))
but it gives error
SyntaxError: invalid syntax
Is there any way I can combine the two cursor.execute
in a single for-loop.
Any suggestion?
I think it can be done like this:
sqlQuery = "SELECT a.xval, a.yval,b.pid,pxval,b.pyval from table1 as a,
(select t1.id as pid,pxval,pyval from <tbl1> t1
left join ( select * from <tbl2> where clubid="+clubid+")
t2 on t1.id=t2.projectid where t1.cityid in ( SELECT cityid
FROM <tbl3> WHERE cbdid ="+cbdid+" group by cityid)
and t1.pxval>0 and t2.distance is null order by projectid)
as b WHERE a.DOMID="+dom_id[i]+"
cursor.execute(sqlQuery)
This will give required data from both the table.
NOTE: If both tables has different row count then tell will be NULL values you can check for that using some condition in your code.
If you want to add this on a single execute, try this:
cursor.execute("SELECT a.xval, a.yval,b.pid,b.pxval,b.pyval from table1 as a, (select t1.id as pid,pxval,pyval from table2 t1 left join (select * from table3 where clubid=?) t2 on t1.id=t2.pid where t1.cityid in (SELECT cityid FROM table1 WHERE domid = ? group by cityid) and t1.pxval>0 and t2.distance is null order by pid) as b WHERE a.DOMID=?",dom_id[i],dom_id[i],dom_id[i])
Hope this helps.
