how to get 5th row values from this table using mysql query without where condition and don't specify any table field name??

Answer 1

You can use this query:

SELECT * FROM your_table ORDER BY column_number LIMIT 4,1

but think about situation, when you table will change.

Answer 2

Tables do not have a fifth row, because they represent unordered sets. You need a column to specify the ordering.

In this case, I presume you mean by the first column. Then you can get the fifth -- based on this column -- by using limit and offset :

select t.*
from t
order by cf_did
limit 1 offset 4;

This can also be written as limit 4, 1 .

offset starts counting at 0 for the first row, so it really means the number of rows to skip.

Also, if you have an index on cf_did (which is true if it is declared as the primary key), MySQL does not actually do a sort.
