First: sorry for my english. 

I disaggree that returning type which user typed is "highly questionable". For
me it was "hightly usable". I have libraries for creating forms and views. I
have special classes for text / varchar/ date fields. Other databases - like
Postgre allows to set different data types for fields like "varchar" or "text",
so i use this library for sqlite and for them.

Until v52 my library worked perfectly - it could read field type from base and
set proper default field format for it. But it has ened now. I set field type
(or just named it) for "date", but i get "text". I have "varchar(64)" wchich
means - one line field, but i have text...

I looked at your post date and got v50, so i have this working again. 

PLS - change it back. Or - if ruining so good option because some users may be
stupid and call database types "hello" - can someone tell mi HOW to get data
type which user entered?
