workday between two dates
The simplest way to calculate the workday between two dates is a calendar table containing the dday section and the other that marks whether all the dates in a known year are off days, then the following query finds all workdays between Start and Stop.
The Code is as follows:
Copy code
Select count (*)FROM calendarWHERE d BETWEEN Start AND StopAnd dayofweek
the original pre-measurement that can be offset by a single sales order to control the impact of the exception demand. For example, if you set the exception update percentage of the prediction set to 50% and add three rows of prediction, the original number of each row is 100, which means that each sales order line (line_id) A maximum of 50 values (100 * 50%) can be predicted for each row ):3. the number of days for reverse push and the number of days for pre-push are the number of working days

MySQL and Oracle date formatting character table
Both Oracle and MySQL databases provide powerful date formatting formats. This article compares the formatting characters of the two databases for your reference:
Common Format String
MySQL:
Date_format (now (), '% Y-% m-% d % H: % I: % s ')
ORACLE:To_char (sysdate, 'yyyy-MM-DD hh24: MI: ss ')
The following is a detailed list of formatting characters. The blank field indicates that no corresponding format exists:
