Hi Fello MySQL users, I am Bala Raju, i have a problem to extract data by writing query, i need u r help. Please help me.
I have two tables, i am giving the tables as attachement, firs table is playersloginfo and second one is playerhanddetails. playersloginfo : This table stores all the loginsession details of the players, who visited the game. playerhanddetails: This table stores all the games the player played during a session. I need to extract the data from both these tables, i need to display the player's logintime, logouttime and the totaltime per a session(these are available in 1 table) and number of games the player played(from 2 table). Please give some ideas to write this queries. (I tried in this way to extract data, i simple selected all the columns and used time difference function, but to find number of games by a player, i need to use second table(playerhanddetails). I am searching second table by conditions of user_name, and date between (logindate, logoutdate) and time between (logintime, logouttime)) playersloginfo: -------------- +------------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +------------+-------------+------+-----+---------+-------+ | user_name | varchar(20) | YES | | NULL | | | ip | varchar(16) | YES | | NULL | | | action | varchar(15) | YES | | NULL | | | logindate | date | YES | | NULL | | | logoutdate | date | YES | | NULL | | | logintime | time | YES | | NULL | | | logouttime | time | YES | | NULL | | | status | varchar(15) | YES | | NULL | | +------------+-------------+------+-----+---------+-------+ playerhanddetails : ----------------- +----------------+-------------+------+-----+---------+-------+ | Field | Type | Null | Key | Default | Extra | +----------------+-------------+------+-----+---------+-------+ | playername | varchar(20) | YES | | NULL | | | handnumber | bigint(20) | YES | | NULL | | | date | date | YES | | NULL | | | time | time | YES | | NULL | | +----------------+-------------+------+-----+---------+-------+
