Prompt What to Do
DUPLICATES Enter y if you want to allow the column to contain
the same value in different rows. For example, if the
column were to contain the last names of people,
you would probably want to allow multiple entries
(because, for example, you might have many
different people with the last name of Smith).
However, if you were creating a column of social
security numbers, then you would enter n to
prevent multiple entries of the same number.
DUPLICATES is displayed for all types except
Serial .
Note: The DUPLICATES prompt is displayed if you
answer yes to an INDEX prompt.
NULLS Enter y if you want to allow the column to have
rows with no values (versus requiring values). For
example, if your table is a list of customer data and
the column you are adding is for the customer's
employer, you might want to allow the NULL value
for the case where the person is unemployed.
Enter n if you want to require a value in each row.
NULLS is displayed for all types except Serial.
ADD STARTING Enter the number that INFORMIX should use as a
NUMBER starting point for numbering rows. INFORMIX
identifies the first row in the table with the number
you enter. As each new row of data is added to the
table, INFORMIX assigns that row the next number
in the sequence. ADD STARTING NUMBER is
displayed only for Serial .
NUMERIC Type the first letter of the numeric you want: Integer,
Smallint, Decimal, or Float.
LENGTH Enter the number of digits the column will store for a
single piece of data. LENGTH is displayed for
Char and Decimal types
SCALE Enter the number of digits that should be displayed
to the right of the decimal point. The decimal digits,
but not the decimal point, occupy part of the field
length you specified in the LENGTH field. SCALE
is displayed after the LENGTH for Decimal .
