Two SPFA times.

When developing a system today, we need to implement such a function.
Query related content based on the selected date, but not filter by the entire date, but filter by year, month, or day splitting, for example, from January 1, 2013 to January 1, February.
In sqlserver, we can directly perform the task according to datePart.
Select * from pays where 1 = 1 and datepart (year, pdate) = 2013 and datepart (month, pdate) = 2 and datepart (day, pdate) = 26 order by pdate
However, access does not wor
Problems with sorting SQL queries
SELECT *, Group_concat (', Concat_ws (' X ', ' sku ', ' quantity-purchased '), '), Group_concat (', ' order_id ', ' ') from ' sale_orders ' WHERE ' shipments ' =0 and ' number ' = $id GROUP by ' recipient-name ', ' ship-address-1 ' ORDER by ' SKU '
May I ask Group_concat (' ', Concat_ws (' X ', ' sku ', ' quantity-purchased '), ') the results can be sorted???
The following is the result of the query:
Ship name Sku-quantity

order of the results without order is the physical order of the database.

Similar to IW, it also represents the ordinal of a week, from the first day of the year to the last seventh day of the year. The values are basically the same. (1-53), for example, 2008-01-01 to 2008-01-07 Count 1,2008-01-09~2008-01-13 2

In the data conversion needs to use the MySQL replace function, here the basic introduction!
For example, you want to replace the ABC of the F1 field in the table TB1 with Def
Update TB1 Set F1=replace (F1, ' abc ', ' Def ');
Replace (STR,FROM_STR,TO_STR)All occurrences of the string from_str in string str are replaced by TO_STR,
DateDiff function
Describe
Returns the time interval between two dates.
Grammar
DateDiff (interval, date1, date2 [, firstdayofweek][, FirstWeekOfYear]])
The syntax for the DATEDIFF function has the following parameters:
Parameter description
Interval must be selected. A string expression that is used to calculate the time interval between Date1 and Date2. For numeric values, see the "Settings" section.
Date1, Date2 must choose. An expression of a date. Two dates used for the calculation.

According to the selected date, the query related content, but not according to the whole date to filter, but based on, year, month, Day split form to filter, such as 2013, February
In SQL Server, we can do it directly according to DatePart.
SELECT * from pays where 1=1 and datepart (year, pdate) =2013 and datepart (month, pdate) =2 and DatePart (day, pdate) =26 order by pdate
