How to update User Logged in Time for a specific user in MySQL?
For this, use ORDER BY along with LIMIT. Let us first create a table wherein we have a column with User id, logged in time, and name −
mysql> create table DemoTable1911 ( UserId int, UserLoggedInTime time, UserName varchar(20) ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1911 values(100,'7:32:00','Chris'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1911 values(101,'5:00:00','David'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1911 values(102,'6:10:20','Mike'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1911 values(103,'3:55:00','Carol'); Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1911;
This will produce the following output −
+--------+------------------+----------+ | UserId | UserLoggedInTime | UserName | +--------+------------------+----------+ | 100 | 07:32:00 | Chris | | 101 | 05:00:00 | David | | 102 | 06:10:20 | Mike | | 103 | 03:55:00 | Carol | +--------+------------------+----------+ 4 rows in set (0.00 sec)
Here is the query to update logged in time for a specific user “Carol” −
mysql> update DemoTable1911 set UserLoggedInTime='12:30:45' where UserName='Carol' order by UserId DESC Limit 1; Query OK, 1 row affected (0.00 sec) Rows matched: 1 Changed: 1 Warnings: 0
Let us check the table records once again −
mysql> select * from DemoTable1911;
This will produce the following output −
+--------+------------------+----------+ | UserId | UserLoggedInTime | UserName | +--------+------------------+----------+ | 100 | 07:32:00 | Chris | | 101 | 05:00:00 | David | | 102 | 06:10:20 | Mike | | 103 | 12:30:45 | Carol | +--------+------------------+----------+ 4 rows in set (0.00 sec)
