Question about setting conditions in searches using SQL

Question

I am trying to search through a table where the "Score" column hs to be in between two numbers.
Table Test:
Name: #
Tom 40
Tom 60
Tom 50
joe 60
If i were to search for "Tom" nomally i get all 3 back. Regardless of the code for SQL(assume it works) will the search display only Tom 40 and Tom 50 is i want between 40 and 60? In other words if the condition field has a valid sql expression that works do i need to write anything to display the data in SQl or it will be fixed automatically?

Answer 1

SQL> select * from test;
NAME SCORE
Tom 40
Tom 60
Tom 50
Joe 60
SQL> select * from test
2 where name = 'Tom';
NAME SCORE
Tom 40
Tom 60
Tom 50
SQL> select * from test
2 where score between 40 and 60;
NAME SCORE
Tom 40
Tom 60
Tom 50
Joe 60
When you use the 'between' operator the search for score includes both 40 and 60. In case of this example, if you were to display only Tom's scores of 40 and 50, you should use the following select statement.
Select * from test
where score >= 40
and score < 60;
SQL> Select * from test
2 where score >= 40
3 and score < 60;
NAME SCORE
Tom 40
Tom 50
