Question

I m trying to dig more in the SQL query , I’m with it.

Yearmo      Back_1_month
-------     ------------
 201202      201201            Where 201202 is Feb 2012 , 201201 is Jan 2012
 201201      201112            
 201204      201203            
 201212      201211

I m confused , how can make it for 201201.

Answer 1

This works in one single sql query :

SELECT CONVERT(VARCHAR(6), DATEADD(month, -1 , convert(datetime, CAST ( 201201 AS VARCHAR(8)) + '01', 112) ) , 112)
