SELECT glider, timestamp, TIMEDIFF(timestamp, UTC_TIMESTAMP()) AS last_contact FROM surfacings INNER JOIN (SELECT MAX(timestamp) AS most_recent FROM surfacings GROUP BY glider) AS tmp WHERE surfacings.timestamp = tmp.most_recent to calculate the amount of time that has elapsed since the last inserted timestamp for each glider. Logically, the TRUNCATE TABLE statement is like a DELETE statement without a WHERE clause that deletes all rows from a table, or a sequence of DROP TABLE and CREATE TABLE statements. The MySQL TRUNCATE TABLE statement allows you to delete all data in a table. TIMESTAMP type columns hold date and time values in the range 00:00:01 UTC to 00:00:00 UTC, stored as number of seconds since the start of the Unix Epoch ( 00:00:01 UTC.) TIMESTAMP columns can be automatically set on row updates to and/or have CURRENT_TIMESTAMP as default value for inserts. In MySQL, you can use DATE or DATE_FORMAT functions. In Oracle, TRUNC function, when applied for a datetime value, truncates it to the specified part (to day, by default). However, the TRUNCATE TABLE statement is more efficient than the DELETE statement because it drops and recreates the table instead of deleting rows one by one. Introduction to the MySQL TRUNCATE TABLE statement.
Note that before MySQL 5.6.4, DATETIME values requires 8 bytes storage instead of 5 bytes. 999999 while 10:01:00.9 requires only 6 bytes, 1 byte for the fractional second precision. sql script or dump file you need to run now and then or on a regular basis contains datetime values filled with zeros instead of null, or if you are like me and using a tool like Navicat to transfer or synchronize entire databases between two servers, you are prone to encounter this error – especially if you have no control on the settings of the remote database server such as that of a shared hosting.Ģ. This error can become a bit of headache if a sync.
