Batch Delete scripts for large tables

I did something silly yesterday. I built a new test database in the company and restored the formal database to the test database,
Change the recovery mode to simple, and then write a script to delete all business tables before this year. Then I went home.
Today, I ran to see that, er, the test database reached more than 200 GB. This makes you realize that the data volume of a single business table is large,
I used a single Delete statement to delete a single transaction, which caused the log to soar to more than 200 GB.
The batch deletion script provided by the big pineapple brother is as follows:

 While   1  =  1  Begin      Delete   Top ( 5000 ) From TB  Where Sysdate <=   '  2013-12-31  '      If   @ Rowcount   <   5000          Break  ;  Waitfor Delay '  00:00:05  ' End
