![]() INSERT INTO messages (sender, senttime, status) VALUES (sender. The syntax is basically the same as INSERT INTO, just replace INSERT by REPLACE. CREATE TEMPORARY TABLE employeeIds ( employeeId int NOT NULL ) INSERT INTO employeeIds ( employeeId ) SELECT employeeid FROM payroll WHERE salary > 2000 UPDATE role SET position 'janitor' WHERE employeeid IN ( SELECT employeeid FROM employeeIds ) The temporary table employeeIds will be deleted when you disconnect from the database - I. If you want the current date in epoch format, then you can use UNIX_TIMESTAMP(). REPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted. Once you call the function, it returns the current date and time. (Within a storedįunction or trigger, NOW() returns the time at which the function orĪs indicated by Erandi, it is best to create your table with the DEFAULT clause so that the column gets populated automatically with the timestamp when you insert a new row: date_time datetime NOT NULL DEFAULT SYSDATE() The simplest method to insert the current date and time in MySQL is to use the now() function. Time at which the statement began to execute. This differs from theīehavior for NOW(), which returns a constant time that indicates the cursor.execute('INSERT INTO ndata VALUES (s)' (q),(values)) in place of cursor.executemany() runs without any errors but it does not insert any values into the table in mysql. ![]() INSERT INTO Register (Name,Ctime) VALUES ('Howard',CURRENTTIMESTAMP) If you want to continue with your table structure. SYSDATE() returns the time at which it executes. Get rid of Date and Time columns and add time stamp. Note that NOW() (which has CURRENT_TIMESTAMP() as an alias), differs from SYSDATE() in a subtle way: We can change this behavior and make NOW() behave in the same way as SYSDATE() by setting sysdate_is_now command line argument to True.
