Delete column in SQL that contains dots and squared brackets
How can one delete a column name [database].[dbo].[my_table].[col_name] in SQL server, that is a column name with dots and squared brackets. In other words, it is the column name that I wanted but prefixed by the database name and shema.
I tried many combinations based on internet e.g. here but didn't succeed.
Thank you.

I don't understand if you want to rename this column or drop it, but here is how to do both
CREATE TABLE JustTest(
Col1 INT,
[[database]].[dbo]].[my_table]].[col_name]]] INT
);
-- To rename the column use this
EXEC sp_rename 'JustTest.[[database]].[dbo]].[my_table]].[col_name]]]',
'NewName',
'COLUMN';
-- If the table is TempTable use this
EXEC tempdb.sys.sp_rename N'#TMP.[[database]].[dbo]].[my_table]].[col_name]]]',
N'NewName',
N'COLUMN';
-- To drop it use this
ALTER TABLE JustTest DROP COLUMN [[database]].[dbo]].[my_table]].[col_name]]];

In a delimited identifier ']' is escaped as ']]', '[' and '.' don't need to be escaped.
So like this:
create table #tt(id int, [[database]].[dbo]].[my_table]].[col_name]]] int)
alter table #tt drop column [[database]].[dbo]].[my_table]].[col_name]]]

In a delimited identifier ']' is escaped as ']]', '[' and '.' don't need to be escaped.
So like this:

alter table #tt drop column [[database]].[dbo]].[my_table]].[col_name]]]
