检测SQL COUNT（*）语句是否具有新值

Question

如何检测COUNT是否具有新值？

我想提醒您COUNT号是否已更改

# Check if file already exist
check = False
for file in os.listdir(path):
    print("I found this file\t" + file)
    if pattern.match(file):
        check = True

if check is True:
    print("\t" + name + " file exist" + "\n")
else:
    print("\t" + name + " does not exist")
