In MariaDB, an extra column TIME_MS has been added to the INFORMATION_SCHEMA.PROCESSLIST table, as well as to the output of SHOW FULL PROCESSLIST.In this article, we will learn to convert datetime object to seconds in Python.when a DATETIME value is compared to a TIME value, the latter is treated as a full datetime with a zero date part, similar to comparing DATE to a DATETIME, or to comparing DECIMAL numbers.Įarlier versions of MariaDB used to compare only the time part of both operands in such a case.It was deprecated in MySQL 4.1.0 (released on The old syntax TIMESTAMP(N), where N is the display width, is no longer supported.This patch fixed a bug when comparing a temporal value using the BETWEEN operator and one of the operands is NULL.The event_time field in the mysql.general_log table and the start_time, query_time, and lock_time fields in the mysql.slow_log table now store values with microsecond precision.DATE_ADD() and DATE_SUB() functions can now take a TIMEĮxpression as an argument (not just DATETIME as before).Incorrectly, though - for example, when comparing a Prove that all result rows are unique anyway, for example, when a primary key Current versions of this patch fix a bug in the following optimization: inĬertain queries with DISTINCT MariaDB can ignore this clause if it can. ![]() These functions will return a decimal number if the result non-zero datetime precision and an integer otherwise (for backward compatibility).
