sqlalchemy calculate date subtract month

The WHERE clause ensures that we’re only considering data for the current month. SUM(order_amount) calculates the total order amount for the current month. COUNT(*) calculates the total number of records (e.g., orders) for the current month. We use DATE_TRUNC(‘month’, order_date) to extract the month from the ‘order_date’ and display it as ‘month’ in the result. It can have value such as MONTH= DATE_TRUNC('month', CURRENT_DATE) AND order_date =) but excludes the start of the next month (= DATE_TRUNC('month', CURRENT_DATE)ĪND order_date < DATE_TRUNC('month', CURRENT_DATE + INTERVAL '1 month') The DATEPART() function accepts two parameters, with the first parameter specifying the value to be retrieved. In order to retrieve the month value of the current date, we can pass the GETDATE() function as a parameter. We can alternatively use DATEPART() function in SQL that helps us retrieve the specific parts of the date such as day, month, year, etc from the supplied date. You can pass your date or use the GETDATE() function as a parameter to get the current value of the month using SQL query statements. The date when this article was written is.

The output of the above query statement is as follows –įrom the output, we can observe that the function retrieves the month value from the date passed to it. Consider the following query statement for the above-mentioned case – SELECT MONTH() AS 'Month of the provided date' Hence, the output of the execution of the above query statement retrieves the current month, as shown in the below image –Īlternatively, we can even supply the literal value retrieved as the output of GETDATE() function in our first query as a parameter to MONTH() function to get the month value. In the above query statement, we have passed the whole function call of GETDATE() as a parameter to the MONTH() function. SELECT MONTH(getdate()) AS 'Present Month' As we have to retrieve the month value of today which is the current month value., we will pass the GETDATE() function as a parameter or the value of GETDATE() function as the parameter. Now, in order to fetch only the month value from the whole time and date string that is retrieved from the GETDATE() function, we can simply use the MONTH() function which retrieves the month value from the passed parameter’s date value. The output of the execution of the above query statement is displayed in the following image, which gives the current date as well as time – Following will be our query statement to do so. Let us try executing a simple query statement using which we will retrieve the value of the current date using the GETDATE() function. In SQL, we use the GETDATE() method to retrieve the value of the current date, which is today’s date. Let’s look at some common methods for retrieving data for the current month. Hadoop, Data Science, Statistics & others Table of Contents In this article, we will learn about the retrieval of the current month value in SQL using different methodologies and functions and how we can apply the conditions in the query statement to use the current month value as the restriction in it. In this case, we first need to fetch the value of the current month. Manier times, we might face the situation in SQL where we need to know the value of the current month and use it to apply the constraint in the query for retrieving data for the only the current month or with reference to the current month. SQL current month is retrieved using the functions available in SQL that are related to date and time, some of which include the MONTH() function and GETDATE() function that can be used togetherly to get the month value of the current month or alternatively, we can make the use of DATEPART() function that can be used to get the value of the current month the month value from current date that is retrieved from the GETDATE() function.
