Are the two codes below the same ?
SELECT * FROM customers WHERE ID BETWEEN 3 AND 7; SELECT ID FROM customers LIMIT 2,5;

what if the first query is changed to
SELECT ID FROM customers
WHERE ID BETWEEN 3 AND 7;
+ 1
No they are not.
The first returns all the columns where ID is between 3 and 7.
The secound returns only the ID column.
+ 1
but are they the same?

you are confusing the limit section
its asking values of id 5 rows starting from 3

They are not same as the I'd data in the table may not be present in ascending order. so both synatax will give you different results.

They are not the same!
In the first you are asking values of ID from 3 to 7.
In the second you are asking values of ID, but only 2 rows starting from 5th row.

Not the same.
First return all columns from the fourth ,end with the 7th.
The second returns the column named ID,from the 3rd,end with the 7th

No, the codes posted below are not the same. The difference in the 2 are as follows:
Code #1 Would return every/all columns between ID 3 & 7 .
Code #2 Would only return the "ID".
