It returns the DATETIME data type (which is the closest to Oracle's DATE). The following Oracle formats are supported: Truncate to day: DD, DDD,J Truncate to month: MM,MON,MONTH,RM Truncate to Year: SYEAR,SYYYY,Y,YEAR,YY,YYY,YYYY TRUNC(date) is same as TRUNC(date, "DD") This patch incorporates a fix for: MDEV-37414 SIGSEGV in Binary_string::c_ptr | Item_func_trunc::get_date Fixing the problem that the code did not take into account that args[1] can return SQL NULL.
