N.C. Gen. Stat. § 1-314: Variance between judgment and execution.

When property has been sold by an officer by virtue of an execution or other process commanding sale, no variance between the execution and the judgment whereon it was issued, in the sum due, in the manner in which it is due, or in the time when it is due, invalidates or affects the title of the purchaser of such property. (1848, c. 53; R.C., c. 44, s. 13; Code, s. 1347; Rev., s. 628; C.S., s. 676.)
