What is the fastest method to fetch only the year from a date in a PostgreSQL table?
The fastest method to fetch only the year from a date in a PostgreSQL table is by using the EXTRACT function in conjunction with the YEAR keyword.
Here is an example query that demonstrates how to fetch only the year from a date column in a PostgreSQL table:

SELECT EXTRACT(YEAR FROM date_column) AS year FROM table_name; |
In this query:
- date_column is the name of the column in the table that contains the date values.

How to use the EXTRACT function to get only the year from a date in PostgreSQL?
You can use the EXTRACT function in PostgreSQL to extract the year from a date using the following syntax:

How to format a date string to extract only the year value in PostgreSQL?
You can use the TO_CHAR function in PostgreSQL to extract only the year value from a date string. Here's an example query to demonstrate this:

|
SELECT TO_CHAR('2021-12-31'::date, 'YYYY') AS year_value;
|
In this query, '2021-12-31' is the date string from which we want to extract the year value. The 'YYYY' format specifier specifies that only the year value should be extracted from the date string. The result of this query will be the year value '2021'.
You can replace the date string '2021-12-31' with your own date string in the query to extract the year value from your desired date.
