Why am I getting an error in setting global sql_mode in mysql?

Question

Is this not the proper way to set multiple modes? What are the advantages of setting session and global modes? which is preffered? I have different users trying to update the database with different UNC values and insted od setting the session mode to 'NO_BACKSLASH_ESCAPES', I though it would make sense to et a gloabl mode for this. Does this make sense?

Answer 1

Use below code, it is working

And it is correct mode:

set global sql_mode="NO_BACKSLASH_ESCAPES,STRICT_TRANS_TABLE,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
