I am having a problem with MYSQL code. I cannot get my database to run when I try to enter a new camera into the database.
Here is what I do:
Then upon clicking submit, I am presented with the 1364 Error: Field "------" doesn't have a default value. I have tried disabling the "strict_trans_table" setting in my Navicat but that still wasn't a valid solution for me. Also, don't mind that the mysql login details are removed; I did that on purpose.
The 'CameraID' value on my Navicat SQL is supposed to be an ID that counts every time a new camera is created. Here's what it looks like:
As you can see it's supposed to be a unique ID however I haven't gotten it to work :( I appreciate all the help I can get.
