是否可以从mysql数据库表中获取数据从特定的id到特定的id?

Suppose there are 100 entries in a table and the need is to fetch data from id 3 to id 7 ( means data from 5 id(s), leaving the id 1 & 2).
Is it possible to do so using php mysql?

    In case of searching in a range of numbers something like this can help.

    select * from test where id between 3 and 7;
    

    Which is similar to this

    select * from test where id >= 3 and id <=7;
    

    In case you want results from 3 to 7 but without id number 6 then something like this can also help.

    select * from test where id in (3,4,5,7);
    

    And again the above query can be re-writen to this

    select * from test where id >= 3 and id <=7 and id<>6;
    

    Check also this example on SQL fiddle where you could also check the time needed for the query result.
