What will be the output of the query SELECT column FROM table ORDER BY column DESC LIMIT 7,10;
-
Would skip the first 7, and then get you the next ten highest.
-
not a valid mysql query
-
Would skip the first 10, and then get you the next 7 highest.
-
None of the above
The LIMIT clause with two parameters works as LIMIT offset, count. LIMIT 7,10 means skip the first 7 rows, then return the next 10. Since ORDER BY column DESC sorts in descending order (highest first), skipping 7 and taking 10 gets rows 8-17 from the top. Option A correctly describes this behavior.
MySQL's LIMIT offset, count syntax skips the first 'offset' rows and then returns the next 'count' rows. Here LIMIT 7,10 means: after sorting by column descending, skip the first 7 (highest) rows, then return the next 10 rows — i.e., ranks 8 through 17 by descending value. This is why 'skip the first 7, then get the next ten highest' is correct. 'Skip 10, get next 7' reverses the offset/count order, and the query is valid MySQL syntax, so 'not valid' and 'none of the above' are both wrong.
