Adatabase planner names a field "organic ingredients_3”. why would this name create possible problems in programming?
it contains capital letters.
it contains a number.
it contains an embedded space.
it contains an underscore.

It contains an embedded space.

Explanation:

Most database platforms won't accept a space within a field name (nor a table name, nor a function name for that matter).

Most database platforms will accept uppercase and lowercase letters as well a numbers and some symbol characters (the underscore would be accepted, while the hypen/minus sign wouldn't).

A better and acceptable name for his field would be OrganicIngredients3
