used a script to rename a column which has caused a problem… sp_RENAME ‘products.isvalid’

used a script to rename a column which has caused a problem…

sp_RENAME 'products.isvalid' , '[_is_valid_system]', 'COLUMN'

Now I have a column name with square brackets in, and I can’t access the column to resolve the problem.

Column Name:

[_is_valid_system]

An attempt to repair the issue like so fails because of the special characters in the command:

sp_RENAME 'products.[_is_valid_system]' , '_is_valid_system', 'COLUMN'

Any way of escaping these characters?

Even if I can just select from the column that will be good enough, but the following obviously does not work because of the special meaning of squared brackets in SQL server.

select [is_valid_system] from products
