Specific Month-day select statement query

I would like to select from a table where the date falls within a specific time each year f.e:
select * from Customer where date >= August 15th and date <= December 20th
Since this will be for a report that runs every year, I do not want to hardcore the date as I will have to change it every year. I would like to have it dynamic to pick the date from August 15th to December 20th of the current year.
I have the below query where I can retrieve the Month and Date:
SELECT DATENAME(month, date) AS Month,DATENAME(day, date) AS Day from Customer
However, I am struggling to have this selection date range.
TIA
In SQL SERVER 2017
maybe this can help you:
SELECT * FROM Customer WHERE date BETWEEN
CONVERT(DATETIME,CONCAT(YEAR(GETDATE()),'08','15')) AND
CONVERT(DATETIME,CONCAT(YEAR(GETDATE()),'12','20'))
This add the current year to a concatenated date you want, then convert it all into datetime type..

Big query sql: month to date query

I have daily data and the code im using creates a report between some dates. I want to replace the date interval with month to date. So every time it will generate a month to date report based on which month we are in. Is there a simple way to do it? thanks :)
An example using BigQuery Standard SQL
SELECT
*
FROM
your_table
WHERE
your_date_field BETWEEN
DATE_TRUNC(CURRENT_DATE(), month) --to get start date of current month
AND
CURRENT_DATE()
You should be able to use that in a WHERE clause and

datepart in sql on year change

I am using datepart function in SP. It is used to compare week and year of specified date.
Now my query arise as new year starts. I have one table called 'Task' and it is storing tasks date wise. Now When I execute SP with DATEPART(YY,'2016-01-05') . It is giving proper 2016's data. But I execute it with DATEPART(ISOWK,'2016-01-05') , it is giving 2015's data also with 2016's data.
I want data from 28th dec,2015 to 2nd jan,2016. Data of the week. And I am not able get data of 1st and 2nd Jan in that. Please help me with this.
Thanks,
ISOWK return the week number
You are trying to get date from 2015-12-28 to 2016-01-02.
The week number of 2015-12-28 is 53 and 2016-01-02 is 53
If you already have your start and end dates decided then you could use a simple query as shown below to filter on date range.
When mentioning date string in your query make sure you stick to this format :yyyymmdd which SQL Server will automatically understand. You don't need DATEPART to get records between two dates.
Query for filtering on a date range
SELECT TaskID, TaskDescription
FROM Tasks
where TaskDate between '20151228' and '20160102'
Another query you can use for date range filtering
SELECT TaskID, TaskDescription
FROM Tasks
where TaskDate >= '20151228' and TaskDate <= '20160102'

Get the month and year now then count the number of rows that are older then 12 months in SQL/Classic ASP

I know this one is pretty easy but I've always had a nightmare when it comes to comparing dates in SQL please can someone help me out with this, thanks.
I need to get the month and year of now then compare it to a date stored in a DB.
Time Format in the DB:
2015-08-17 11:10:14.000
I need to compare the month and year with now and if its > 12 months old I will increment a count. I just need the number of rows where this argument is true.
I assume you have a datetime field.
You can use the DATEDIFF function, which takes the kind of "crossed boundaries", the start date and the end date.
Your boundary is the month because you are only interested in year and month, not days, so you can use the month macro.
Your start time is the value stored in the table's row.
Your end time is now. You can get system time selecting SYSDATETIME function.
So, assuming your table is called mtable and the datetime object is stored in its date field, you simply have to query:
SELECT COUNT(*) FROM mtable where DATEDIFF(month, mtable.date, (SELECT SYSDATETIME())) > 12

calculate leave year from anniversary start date

I am trying to calculate someone holiday year start and end dates based on the anniversary of their joining date.
For example if someones joining date is 23/10/09 i need two fields calculated from this date which would be 23/10/13 for the start of their holiday year and the end of their leave year would be 22/10/14.
Basically i need a query that looks at the dd/mm of the joining date and the current date and calculates the two dates i require.
Another example would be joining date 01/02/10 and the start date of the leave year would be 01/02/14 and the end date date would be 31/01/15. The field name in my SQL database is
[emp_join_date]
Any ideas ?
DATEADD() would be the function you need I believe:
declare #emp_join_date datetime = '2009-10-23'
select #emp_join_date as emp_join_date,
DATEADD(YEAR,4,#emp_join_date) as holiday_start_date,
DATEADD(YEAR,5,#emp_join_date)-1 as emp_end_date
