Refreshing a table using CREATE TABLE, DROP and Rename

A read-only database (database1) is updated via log shipping every minute, then a procedure queries multiple tables in it and refreshes a large table on database2.

For this process I

• run an "expensive" query against database1 and generate a new Table in database2 (Table_A_TEMP)

  BEGIN TRAN
  DROP TABLE Table_A
  RENAME Table_A_TEMP to Table_A
  COMMIT
  

Does it look too ugly? Otherwise I would have to create a very complex verifications and updates.

Suggestions to minimize locks?
