My db has a table with a column defined thus:
body_size text default '0.0'
whose purpose is to hold the size of the item that the row represents. All rows
contain a value but as a string to one decimal place, not a number. So the
column contains strings such as '0.0', '3.7', '22.9', etc. All are positive.
Now I want to use the body_size in an ORDER BY so I'll need SQLite to convert
the values to a float. What will be the best function to use? I'd thought of
select col1, col2 from mytable order by round(body_size,1)
however the doc doesn't specify whether round accepts a non-numeric argument.
select col1, col2 from mytable order by abs(body_size)
would be better, but I wonder which is fastest (although speed may not matter
too much, the typical select shouldn't return more than few thousand rows).
