The SELECT TOP clause is used to specify the number of records to return. The SELECT TOP clause is useful on large tables with thousands of records. Returning a large number of records can impact performance.
Syntax: SELECT TOP number * column_name(s)
FROM table_name
WHERE condition;


The SELECT DISTINCT statement is used to return only distinct (different) values. Inside a table, a column often contains many duplicate values; and sometimes you only want to list the different (distinct) values.
Syntax: SELECT DISTINCT column1, column2, ...
FROM table_name;


The BETWEEN operator selects values within a given range. The values can be numbers, text, or dates. The BETWEEN operator is inclusive: begin and end values are included.
Syntax: SELECT column_name(s)
FROM table_name
WHERE column_name BETWEEN value1 AND value2;
