underscore ( _ ) - Fill in the blanks

SQL

data readin;
input name $ Section $ Score;
cards;

Atul . 77
Priya . 45
Sandy A 67
David B 39
Rahul . 95
Sahil C 84
Savitri B 65
;
run;

data readin1;
set readin;
where name like 'S%';
run;

Output:

In a given dataset, the above statements would produce the same result in both cases. Examples:

```
where name like '%ul';
```
Output: It contains all the data where the name ends with 'ul'.
```
where name like '_ah%';
```
Output: It contains all the data where the name contains atleast 3 characters, which must contain 'ah' at second place.
```
where name like '_a___';
```
Output: It contains all the data where the name contains atleast 5 characters, which must contain 'a' at second place.
