Hi Fabio,
Hmmm. Maybe you could explain in some more detail what is the actual
business problem you're trying to solve. A parameter that governs in
which of 30 columns the current date has to be inserted sounds as if the
best solution would be a redesign of your table - but I can only say for
sure if I know more about your actual problem and your current table
structure.

I had used ellipsis as a placeholder for the value to delete. Now that I
know it's the current date, I can complete my proposed code. I've also
added a third column and ellipsis to show how you can extend this to as
many columns as you need.
INSERT INTO OT (OTFechaBorrador, OTFechaAAsignar, ThirdColumn, ...)
SELECT CASE WHEN @eotId = 1 THEN CURRENT_TIMESTAMP ELSE NULL END),
CASE WHEN @eotId = 2 THEN CURRENT_TIMESTAMP ELSE NULL END),
CASE WHEN @eotId = 3 THEN CURRENT_TIMESTAMP ELSE NULL END),
...
If called with @eotId equal to 1, this will create a row with
CURRENT_TIMESTAMP in the first column (OTFechaBorrador) and NULL in the
two (or more) other columns. If @eotId is 2, OTFechaAAsignar will be the
current datetime and the other columns are NULL. Etc, etc.
