I have a big student database, it has only one table. I want to select 10 student each department on a single mysql query. +---------------------------------------------------------+----------------------+ | student | Dept | +---------------------------------------------------------+----------------------+ | gooch | physics | | aaaaa | mathss | | dvssdg | maths | | sfgsfg | chemistry | | gcbcvb | chemistry | | dgsgsfg | arch | I have a big list like this.. I have to select ten student from each department. how shall I achieve it?
Hi, You can do this using some scripting and the logic will be: - ~ First fetch the distinct names of all the departments ~ Run a loop for each department and pick top ten records from each record set Hope this helps. Cheers, ~Maneet
Say, If I have 100 department then the loop will run for 100 times and sql statement will run for 100 times. I dont want it to run the 100 times I just want it to happen only once.
The only way to do it in one go is by a query you will have to split the table into two so that u can write one query with joins to fetch it with one query. Hope this helps,
