Please note, as of MySQL 8.0.17, the &&
operator is deprecated and support for it will be removed in a future MySQL version. Applications should be adjusted to use the standard SQL AND
operator.
If you're using MySQL 5.7 or older, which most of you are if you're using GoormIDE, then you don't have to worry about this right now. But, in newer versions of MySQL (8.0.17 and newer) you will need to replace &&
with AND
.
