Neuropathies of all types generally fall into three categories: acquired, hereditary and idiopathic (no known cause). One of the most common forms of an acquired neuropathy is diabetic neuropathy, which is the result of poorly controlled blood sugar levels in people with diabetes.
In design,(Quark, Photoshop, Illustrator, Indesign) construction,(blueprints) or print, (8.5 x11 for example), it s width x length. Mathematicians, for some reason, use the reverse, length x width. But otherwise, the most common accepted use is Width first. I agree.
length is an optional parameter that specifies how many characters to extract. If this parameter is not used, SUBSTR will return everything from the start_position to the end of the string. If the start_position is specified as 0, substr treats start_position as 1, that is, as the first position in the string.
