Select query for fetching records from two tables

padmaneha

Hi

I have created two tables which are movies table and videos table

Columns of movies table are movie id, movietitle, moviereviewid and the select statement which I have written to fetch count of reviews is as follows

select movieid, count(moviereviewid) as Moviereviewscnt from movies
where moviereviewid >0

columns of videos table are videoid, videoname and movievideoid and the select statment which I have written to fetch count of videos is as follows

select movieid, count(videoid) as Vidoescnt from videos
where videoid >0

I want to write a select query to fetch all those movies which has got moviereviews and movievideos in a single table i.e. it should have
movieid, moviename, moviereviewscnt and movievideoscnt

In other words it should show only those movies which has reviews and videos which is >0

Hi,
Your requirement is not clear to me, it will be more clear if you can provide some sample data and output you want.

Any way try the following query, probably will help you.

Thanks

Hi

Thanks for your response but the query which you gave doesnt work. It displays the same cnt for movie reviews and videoreviews

Let me explain you in detail

As I said I have got two tables like one is 'Food table' and the other one is the 'Videos' table

Columns which I have created in 'Food' table are 'foodid' and 'blogcid'
colcumns which I have created in Videos table are 'videoid, 'destid', 'videotitle'

Common column for the above two tables are foodid and destid which has the same content id for inner join

I need to fetch records of those foodids which has got blogs and videos

For example

Food id blog cid
3 12356
9 15265
15 18963
19 0
13 22156

videoid videotitle destid
9 paneerpakora 3
11 aloogobhi 9
16 chinese chickensalad 15
45 Chicken 19
0 tomato soup 13

From the above data I have to fetch only those records which has blogs and videos. In other words I need a select query to fetch records of those dishes alone which has blogs >0 and destid >0 which means that fetched foodids should have both blogs and videos it should fetch records which doesnt have blogs or videos.

Hi,
Your requirement is not clear to me, it will be more clear if you can provide some sample data and output you want.

Any way try the following query, probably will help you.

Expand|Select|Wrap|Line Numbers

1. select movieid, movietitle as moviename,
2.        count(moviereviewid) as Moviereviewscnt ,
3.        count(videoid) as Vidoescnt
4. from movies inner join
5.      videoid on videoid.movieid = movies.movieid
6. where moviereviewid >0 and videoid > 0
7. group by movies.movieid
8.

Hi

Thank you for your response. Query doesnt give the expected result.

Here is the sample data :

Food id blog cid
3 12356
3 12357
3 12358
9 15265
15 18963
15 18964
19 0
13 22156

videoid videotitle destid
9 paneerpakora 3
10 paneerpakora 3
11 aloogobhi 9
16 chinese chickensalad 15
17 chinese chickensalad 15
18 chinese chickensalad 15
45 Chicken 19
0 tomato soup 13


Here is the expected result:

Output should display as given

Food id blogcnt Videocnt
3 3 2
9 1 1
15 2 3
13 1 1

On executing the query it should display only those records for which blogs and videos are existing. It should not dipslay the records there is no videos or if there is no blogs. In other words it should fetch only those records for which
videos and blogs are posted, displaying the count of blogs and count of videos as given above
