I have the following table where there are two relevant fields for searching, this is 'from' and 'to' and represents the range of employees and then the field 'InitialQMSDays' represents the value that I want to return.
So if I have a search value of say 6, it would look at that value and find it between the 6 - 10 row, and return 2.
any ideas?
SELECT InitialQMSDays
FROM my_table
WHERE 6 BETWEEN `From` AND `To`;

Wanted to delete complete row, which contains NULL entries in sql with command
DELETE FROM student WHERE ID=NULL;
What is wrong in this code?
Your syntax is incorrect you need to check for IS NULL
DELETE FROM student WHERE ID IS NULL;

where a.id_position = b.id_position (+) and c.id_karyavan (+) = b.id_karyavan
order by a.id_position
