The MySQL InnoDB transaction has level four isolation, and the default is "repeatable read" (Repeatable Read). Uncommitted read (read UNCOMMITTED). Another transaction modified the data, but it has not yet been submitted, and the select in this transaction reads the uncommitted data (dirty reads). Submit read (Read committed). This transaction reads the most current data (after other transactions have been committed). The problem is that in the same transaction, two times the same select will re

Therefore, the best way to make a PDF file is to edit the content in Word or PPT First, then use Foxit Phantom to convert it to PDF.
