Count months between two timestamp on postgresql?

Question

I want to count the number of months between two dates.

Doing :

SELECT TIMESTAMP \'2012-06-13 10:38:40\' - TIMESTAMP \'2011-04-30 14:38:40\';
         


        

Answer 1

Gives the differenece of months of two dates

   SELECT ((extract( year FROM TIMESTAMP '2012-06-13 10:38:40' ) - extract( year FROM TIMESTAMP '2011-04-30 14:38:40' )) *12) + extract(MONTH FROM TIMESTAMP '2012-06-13 10:38:40' ) - extract(MONTH FROM TIMESTAMP '2011-04-30 14:38:40' );

The Result : 14

Have to extract months seperately for both the dates and then the difference of both the results
