Remove all data from table for a year

Product:
Microsoft SQL Azure

Issue:

How remove all rows of data from table when the date column is INT and contain both year and date?

Suggested solution:

In SQL SSMS write like this (to erase all rows with year 2024) :

DELETE FROM [DM].[dbtablename]
where 1=1
and SUBSTRING (( CAST ( [key_dimdate] AS varchar) ), 1 , 4 ) = '2024'

if the key_dimdate format is ‘20240112’ as a INT
