It is a python code. I am sorry for improper indentation. I am trying to read some information from a NetCDF file and wanted to write it to MySQL and i got some errors that I cannot solve.
I believe that I put everything in correct syntax. I do not understand why such error takes place..
Here is the detail.

回答1:
REFERENCES is a MySQL reserved word. If you wish to use it as a column name you will need to surround it with backticks (`).
