Why I do get [ERR] 1052 - Column 'RECNO' in group statement is ambiguous (MySQL)

I couldn't understand why Column 'RECNO' in group statement is ambiguous

You're having an occurrence of "RECNO" in your query without a table alias in front of it.

Seeing there are multiple tables in your query (for instance m and i) that have the field RECNO in it; probably a later RECNO (I see one in the last and, where you put OR RECNO LIKE '%ayten%'; which might need one of those aliases.

It might be a good practice to use the aliases in front of every field at all times; it avoids these errors, and you can easily see where the fields come from :).
