How to Convert Number to Month Name In Postgresql?

2 minutes read

In PostgreSQL, you can convert a number representing a month into its corresponding month name using the to_char() function. You can achieve this by providing the number representing the month, followed by the format 'Month' as an argument to the to_char() function.


For example, if you have a table with a column month_number containing numbers representing the months (1 for January, 2 for February, etc.), you can retrieve the corresponding month name using the following query:

1
2
SELECT to_char(to_date(month_number::text, 'MM'), 'Month') AS month_name
FROM your_table_name;


This query will convert the number in the month_number column into its corresponding month name and return the result in the month_name column.


How to convert a decimal value representing a month to the nearest whole month name in PostgreSQL?

You can use the to_char function in PostgreSQL to convert a decimal value representing a month to the nearest whole month name. Here is an example query:

1
SELECT to_char(to_date('1970-01-01', 'YYYY-MM-DD') + interval '1 month' * 5, 'Month');


In this query, interval '1 month' * 5 is used to add 5 months to the base date '1970-01-01' and to_char function with the 'Month' format mask is used to convert the resulting date to the nearest whole month name.


You can replace the 5 with your decimal value representing the month you want to convert.


How to convert a numeric value representing a month into the corresponding month name in PostgreSQL?

You can convert a numeric value representing a month into the corresponding month name in PostgreSQL by using the to_char function. Here is an example:

1
SELECT to_char(to_timestamp('1', 'MM'), 'Month') AS month_name;


In this example, '1' is the numeric value representing the month (January). The to_timestamp function is used to convert the numeric value into a timestamp, and the to_char function is used to format the timestamp as the month name.


You can replace '1' with any other numeric value representing a month to get the corresponding month name.


What are the different methods available for converting a number to month name in PostgreSQL?

There are several methods available in PostgreSQL to convert a number to a month name:

  1. Using the to_char() function:
1
SELECT to_char(to_date('1', 'MM'), 'Month');


  1. Using the date_trunc() function:
1
SELECT date_trunc('month', make_date(2000, 1, 1))::date; 


  1. Using the extract() function:
1
SELECT extract(month from to_date('1', 'MM'))::int;


  1. Using the array position:
1
SELECT array_position(ARRAY['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'], 'January');


These are some of the methods available in PostgreSQL to convert a number to a month name.
