Hi Fabio,

You can't insert into just one column - you insert a complete row, and
you'll have to give values (either real values or NULL) for all columns.
Sure, the language permits you to leave out some columns, but that's
just a shorthand way for specifying that you want to insert the defined
DEFAULT value (if any) or NULL in all the other columns.

To do what you appear to want (and I *really* hope that this is an
extremely simplified illustration of the real problem, because if this
is your real procedure, you have much, much bigger problems), you can
either use the code posted by MGFoster, or use

INSERT INTO OT (OTFechaBorrador, OTFechaAAsignar)
SELECT CASE WHEN @eotId = 1 THEN .... ELSE NULL END),
CASE WHEN @eotId = 2 THEN .... ELSE NULL END)
