Hi everyone
1
2
00:00:02,304 --> 00:00:07,936
We have learnt the fundamental queries in SQL. It is now time to test what we have learnt
2
3
00:00:08,192 --> 00:00:12,032
First thing we have to do is, we'll have to retrieve all data from the
3
4
00:00:12,288 --> 00:00:13,568
Table science class
4
5
00:00:14,080 --> 00:00:15,104
This should be simple
5
6
00:00:16,128 --> 00:00:17,920
Now let us put some filter on it
6
7
00:00:18,944 --> 00:00:24,064
I want you to retrieve only name of students who have scored more than 60 marks
7
8
00:00:24,832 --> 00:00:27,648
Not all the columns only name of students
8
9
00:00:27,904 --> 00:00:28,672
who have scored
9
10
00:00:28,928 --> 00:00:30,208
More than 60 marks
10
11
00:00:31,232 --> 00:00:32,000
Next
11
12
00:00:32,256 --> 00:00:32,768
Retrieve
12
13
00:00:33,024 --> 00:00:34,304
All data of students
13
14
00:00:34,560 --> 00:00:38,400
Who have scored more than 35 but less than 60 marks
14
15
00:00:39,168 --> 00:00:41,984
probably you are already guessing that it will have two conditions
15
16
00:00:42,496 --> 00:00:43,264
And you know
16
17
00:00:43,776 --> 00:00:46,080
What operator to use when you want to add
17
18
00:00:46,336 --> 00:00:47,360
More than one condition
18
19
00:00:49,152 --> 00:00:52,224
Next is you want to get all other students
19
20
00:00:52,736 --> 00:00:55,552
so, all the list that you got in point 3
20
21
00:00:56,320 --> 00:00:57,088
You want to get
21
22
00:00:57,344 --> 00:01:00,672
Any other student who was not part of that previous list
22
23
00:01:01,696 --> 00:01:05,280
These are students who have scored less than or equal to 35
23
24
00:01:05,536 --> 00:01:07,584
or more than or equal to 60 marks
24
25
00:01:07,840 --> 00:01:08,608
Try this out
25
26
00:01:08,864 --> 00:01:10,656
If you are able to do it great
26
27
00:01:10,912 --> 00:01:12,960
Revisit the video if you are not able to do it
