Hi everyone
1
2
00:00:03,328 --> 00:00:06,400
So now we have covered all the string functions
2
3
00:00:07,936 --> 00:00:11,776
In string functions you learnt how to find out length of characters
3
4
00:00:12,288 --> 00:00:14,336
Change characters to upper or lowercase
4
5
00:00:15,104 --> 00:00:16,896
Find out substrings in a string
5
6
00:00:17,664 --> 00:00:22,272
Trim extra spaces or any other extra special character from a string
6
7
00:00:23,296 --> 00:00:25,088
And to create an aggregate string
7
8
00:00:26,624 --> 00:00:28,672
Let us test this out in this exercise
8
9
00:00:30,208 --> 00:00:30,720
First
9
10
00:00:31,232 --> 00:00:32,512
I want you to find out
10
11
00:00:32,768 --> 00:00:34,048
The product name
11
12
00:00:34,304 --> 00:00:37,376
Which has maximum length. so out of all the product names
12
13
00:00:37,632 --> 00:00:40,192
Which product name has the maximum length
13
14
00:00:40,704 --> 00:00:43,776
Next let us see if you are able to do concatenation
14
15
00:00:44,288 --> 00:00:50,432
I wanted to join product name subcategory and category from the product table into a column
15
16
00:00:50,688 --> 00:00:52,224
Called product details
16
17
00:00:52,480 --> 00:00:52,992
So
17
18
00:00:53,248 --> 00:00:55,552
Your resultset will have four columns
18
19
00:00:56,320 --> 00:00:57,088
Product name
19
20
00:00:57,344 --> 00:00:59,136
Sub category category
20
21
00:00:59,392 --> 00:01:04,256
And the fourth one is product details which is concatenation of the previous three columns
21
22
00:01:05,280 --> 00:01:06,560
In the third activity
22
23
00:01:07,584 --> 00:01:09,888
If you go and look at the product IDs
23
24
00:01:10,400 --> 00:01:11,680
In your product table
24
25
00:01:12,192 --> 00:01:14,496
you will see it consists of three parts
25
26
00:01:15,520 --> 00:01:17,312
Which is separated by hyphens
26
27
00:01:18,336 --> 00:01:20,384
Analyze these three parts
27
28
00:01:21,152 --> 00:01:27,296
Check the length of all these three parts and separate these three parts out so in your resultset
28
29
00:01:27,552 --> 00:01:28,832
What I want is
29
30
00:01:29,088 --> 00:01:31,136
Your first column should be the product ID
30
31
00:01:31,648 --> 00:01:34,720
The second column should have the first part of the product ID
31
32
00:01:34,976 --> 00:01:40,864
Third column should have the second part of product ID and fourth column should have the third part of product ID
32
33
00:01:41,120 --> 00:01:42,912
And in the last activity
33
34
00:01:43,168 --> 00:01:45,472
You have to get a list of all the
34
35
00:01:45,728 --> 00:01:47,264
Chairs or tables
35
36
00:01:48,032 --> 00:01:49,056
From your products table
36
37
00:01:49,568 --> 00:01:52,384
So wherever subcategory is chairs or tables
37
38
00:01:52,896 --> 00:01:55,200
I want you to get the list of all those products
38
39
00:01:55,712 --> 00:01:58,016
and aggregate those product names
39
40
00:01:58,528 --> 00:02:00,320
Into a comma separated list
40
41
00:02:01,088 --> 00:02:04,416
So in your final table it will have only two rows
41
42
00:02:05,184 --> 00:02:06,208
In the First row
42
43
00:02:06,720 --> 00:02:07,744
It will have
43
44
00:02:08,000 --> 00:02:10,816
List of all shares which are separated by comma
44
45
00:02:11,328 --> 00:02:16,448
And in the second row it will have list of all tables separated by comma
45
46
00:02:17,472 --> 00:02:19,520
If you are able to do this exercise
46
47
00:02:19,776 --> 00:02:22,592
You have successfully learnt the lesson taught in the
47
48
00:02:22,848 --> 00:02:24,128
String functions section and you are now ready to move to next section
