“Why do NULL values get inserted as strings when using mysql LOAD DATA INFILE after dumping the data with mysql -e”
Unfortunately this team only has control over the import, not the existing export. Their only option found was to replace occurrences of NULL with N after getting the import file.
A team again reminds us to be aware that the default file system in OSX is case insensitive. They thought this was the reason git would not commit a lowercase file rename for them. However, this setting was later found for your .git/config file.
