QUESTION
I need some help with inserting some data into a sql server table using the IF clause. I have the return of an API that I insert in the table of the sql server. However, as I will schedule my code every day to get the update from the API to see if there is anything new, but every time it executes the code it inserts the same information into the table.
The most logical thing I thought was to make a select in the table where I will insert the data and create an IF, where it compares what is in the table and my return from the array. If it’s the same, it doesn’t do anything, if it’s different, insert it. However, the else is not being validated, even if the return of the IF is false.
I've tryed If, ifelse, If(): else: endif; but i couldnt.
Can someone help me please?

I solved this issue leaving the rule inside the insert, changing it to insert select instead of making the select and then compare with what would be inserted.
Here's how it went:

I'm trying to create a binary classifier with TensorFlow, capable of detecting with a person is wearing a surgical Mask. The thing is, I've created a dataset for training containing 2.2k cropped faces of people wearing masks and another 2.2k cropped faces of people NOT wearing masks (my face included). Trainned the CNN for 100 epochs(almost 24hrs) and got an accuracy around 84.25%(val_acc). But my CNN still predicting wrong most of the time! I've tried more than a dozen CNN architectures and even Transfer Learning using MobileNetV2 but my results still pretty bad. Am I doing something wrong?
Part of my training code is:
