Today, I came to phpstudy. I found that MySQL could not be opened and reported this error. After a round of search, I solved the problem
Modify mysql.ini

sql_ mode =‘STRICT_ TRANS_ TABLES,NO_ ZERO_ IN_ DATE,NO_ ZERO_ DATE,ERROR_ F
OR_ DIVISION_ BY_ ZERO,NO_ AUTO_ CREATE_ USER,NO_ ENGINE_ ‘
I solved it like this. It depends on whether you can do it or not

Others have provided the following solutions
1. Phpstudy upgrade, SQL_ Mode is followed by more spaces. Just delete the spaces

2、 Directly annotate SQL_ Mode line content（ After I do this, MySQL starts and then stops, and goes back and forth ε=( ´ ο｀*))) Alas)

3、 Remove SQL_ No in mode_ AUTO_ CREATE_ USER

4、 SQL_ mode = NO_ AUTO_ CREATE_ USER,NO_ ENGING_ SUBSTITUTION

All the above are modified in mysql.ini
