Suppose COMPANY table has the following records:

---------- ---------- ---------- ---------- ----------
1 Paul 32 California 20000.0
2 Allen 25 Texas 15000.0
3 Teddy 23 Norway 20000.0
4 Mark 25 Rich-Mond 65000.0
5 David 27 Texas 85000.0
6 Kim 22 South-Hall 45000.0
7 James 24 Houston 10000.0

Here is an example, it will update the customer ID to address 6:

sqlite> UPDATE COMPANY SET ADDRESS = 'Texas' WHERE ID = 6;

Now, COMPANY table has the following records:

ID NAME AGE ADDRESS SALARY
---------- ---------- ---------- ---------- ----------
1 Paul 32 California 20000.0
2 Allen 25 Texas 15000.0
3 Teddy 23 Norway 20000.0
4 Mark 25 Rich-Mond 65000.0
5 David 27 Texas 85000.0
6 Kim 22 Texas 45000.0
7 James 24 Houston 10000.0

If you want to change all values ​​COMPANY ADDRESS SALARY column of the table and you do not need to use the WHERE clause, UPDATE query as follows:

sqlite> UPDATE COMPANY SET ADDRESS = 'Texas', SALARY = 20000.00;

Now, COMPANY table has the following records:

ID NAME AGE ADDRESS SALARY
---------- ---------- ---------- ---------- ----------
1 Paul 32 Texas 20000.0
2 Allen 25 Texas 20000.0
3 Teddy 23 Texas 20000.0
4 Mark 25 Texas 20000.0
5 David 27 Texas 20000.0
6 Kim 22 Texas 20000.0
7 James 24 Texas 20000.0
