SELECT column_name(s)FROM table_nameWHERE column_name LIKE pattern
 

For example, if you run like in the "person" table:

P_Id LastName FirstName Address City
1 Hansen Ola Timoteivn 10 Sandnes
2 Svendson Tove Borgvn 23 Sandnes
3 Pettersen Kari Storgt 20 Stavanger

Now, we want to select people to live in a city and start with "S" from the above table.

We use the following SELECT statement:

SELECT * FROM PersonsWHERE City LIKE 's%'

The '%' symbol can be used to define the pattern before and after a wildcard (missing mail mode.

The result set looks like this:

P_Id LastName FirstName Address City
1 Hansen Ola Timoteivn 10 Sandnes
2 Svendson Tove Borgvn 23 Sandnes
3 Pettersen Kari Storgt 20 Stavanger

Next, we want to select people to live in a city, and the last "S" takes a seat from "person.

We use the following SELECT statement:

SELECT * FROM PersonsWHERE City LIKE '%s'
  
  
P_Id LastName FirstName Address City
1 Hansen Ola Timoteivn 10 Sandnes
2 Svendson Tove Borgvn 23 Sandnes
 

Next, we want to select people to live in a city, including "people" in the pattern of "tomato infertility.

We use the following SELECT statement:

SELECT * FROM PersonsWHERE City LIKE '%tav%'
   
   
_Id LastName FirstName Address City
3 Pettersen Kari Storgt 20 Stavanger
 

It is also possible that the selected person lives in a city and does not include the "man" table in the pattern "tomato infertility" by using the non-keyword.

We use the following SELECT statement:

SELECT * FROM PersonsWHERE City NOT LIKE '%tav%'
 
    
    
_Id LastName FirstName Address City
1 Hansen Ola Timoteivn 10 Sandnes
2 Svendson Tove Borgvn 23 Sandnes
