Oracle TRUNC Date Function By Practical Example

Hi All, I have a requirement to find the first day and last day of the previous quarter from the sysdate. For eg: If today's date is 6-Feb-2007 then I want to find the first day of the previous quarter that is 1-Oct-2006 and last day of previous quarter as 31-Dec-2006. Any pointers to the same will be highly appreciated. Regards, Soumy WHERE last_day(trunc(datefield))=last_day(trunc(sysdate)) Here we're just checking if the last day of the months are equal, same result. The trunc is a safety measure here to strip off any timestamps which could give bad results. One issue with this approach is if datefield is indexed, the 1st query will run a lot faster than the 2nd one because using a function on a field generally disrupts.

ORACLE LAST_DAY() Function By Practical Example

In Oracle, TRUNC function, when applied for a datetime value, truncates it to the specified part (to day, by default). In MySQL, you can use DATE or DATE_FORMAT functions. Oracle: -- Truncate the current date and time (time part will be set to 00:00:00) SELECT TRUNC(SYSDATE) FROM dual; # 2016-04-07 SELECT TRUNC(SYSDATE, 'DD') FROM dual; # 2016-04-0 Term: SYSDATE Definition: In Oracle PL/SQL, SYSDATE is a pseudo column which always returns the operating system's current datetime value of DATE type. The format of the DATE output depends on the value of NLS_DATE_FORMAT initialization parameter. Note that: The SYSDATE function requires no arguments. You cannot use the SYSDATE function in the condition of a CHECK constraint

Oracle ADD_MONTHS Function with Example

TO_CHAR (SYSDATE, 'DAY:DDMONTHYYYY')----- Lundi: 21 Ao û t 2017 : In For Oracle, if two dates being compared represent the same value in UTC, then they are equal. Oracle: TIMESTAMP '2017-01-15 8:00:00 -8:00' == TIMESTAMP '2017-01-15 10:00:00 -6:00' In N1QL currently in order to compare full date values we need to convert them to milliseconds. N1QL: STR_TO_MILLIS(2017-01-31T05. PS. If someone says Oracle stores dates as strings, punch them in the face. I take no responsibility for the outcome of this action. PPS. If you want to know more about Oracle dates, timestamps and intervals, you might want to look at this article Notice that the dataset expands again to include PAT3. PAT3 had made a visit on sysdate and sysdate+1 so it shows in the report. It also shows PAT1 and PAT2 visits that are outside of our specified dates. This may be desirable when initially process of data discovery That's why SELECT sysdate FROM dual works like SELECT GETDATE(). Both return one row. If you issued a SELECT sysdate FROM employees, you would get one sysdate value per employee in the data table. So, in an Oracle environment, selecting something from dual is just a convenient, common way to select one thing back SQL Server 常用日期函数DateDiff()、GetDate() 以及oracle 日期常用函數 (SYSDATE、日期格式)等详解一、GetDate() 函数作用:GetDate() 函数用于返回当前的时间和日期,返回值样式举例:2013/10/29 9:11:05语法:GetDate()ASP 实例:'数据库链接定义
