How can we get only month and year in SELECT SQL?

 To retrieve only the month and year from a DATE or DATETIME column in SQL, you can use different functions depending on the SQL database you're working with. Here's how you can do it in some common SQL databases:

1. MySQL

In MySQL, you can use the DATE_FORMAT() function to extract the month and year from a DATE or DATETIME column:

SELECT DATE_FORMAT(your_date_column, '%Y-%m') AS month_year
FROM your_table;
  • %Y gives the four-digit year.
  • %m gives the two-digit month.

2. PostgreSQL

In PostgreSQL, you can use the TO_CHAR() function to format the date:

SELECT TO_CHAR(your_date_column, 'YYYY-MM') AS month_year
FROM your_table;

3. SQL Server

In SQL Server, you can use the FORMAT() function (available from SQL Server 2012 onwards):

SELECT FORMAT(your_date_column, 'yyyy-MM') AS month_year
FROM your_table;

Alternatively, you can also use CONVERT() and DATEPART() if you need a more basic approach:

SELECT CAST(YEAR(your_date_column) AS VARCHAR(4)) + '-' + RIGHT('0' + CAST(MONTH(your_date_column) AS VARCHAR(2)), 2) AS month_year
FROM your_table;

4. Oracle

In Oracle, you can use the TO_CHAR() function similarly to PostgreSQL:

SELECT TO_CHAR(your_date_column, 'YYYY-MM') AS month_year
FROM your_table;

Example with a DATE column:

SELECT DATE_FORMAT(order_date, '%Y-%m') AS month_year
FROM orders;

This will return results like:

2023-01
2023-02
2023-03

Summary:

  • MySQL: DATE_FORMAT(your_date_column, '%Y-%m')
  • PostgreSQL: TO_CHAR(your_date_column, 'YYYY-MM')
  • SQL Server: FORMAT(your_date_column, 'yyyy-MM') or string concatenation with YEAR() and MONTH()
  • Oracle: TO_CHAR(your_date_column, 'YYYY-MM')
