Converting data on insertion
The DATETIME conversion option

•
Use any character other than Y, M, J, or D to indicate the separator
character you want Adaptive Server IQ to skip over. You can even use
blanks.
•
If a
format includes only a year and a day number within the year,
DATE
Adaptive Server IQ treats the date as a Julian date. For example, 1998-33
is the 33rd day in the year 1998, or February 2, 1998.
•
If a year is specified with only two digits, for example "5/27/32", then
Adaptive Server IQ converts it to 19yy or 20yy, depending on the year and
on the setting of the
NEAREST_CENTURY
setting
Default (50)

Use the
conversion option to insert ASCII data that is stored in a
DATETIME
fixed format into a
TIME
converts the ASCII data input to binary and specifies the format of the input
data. (The
format is used internally to interpret the input; it does not
DATETIME
affect the storage or output format of the data.) See the
for more information.
For compatibility with previous releases, you can specify that a column
Note
contains
data. However, such data is stored internally as the
DATETIME
equivalent format,
TIMESTAMP
Here is the syntax:
DATETIME (' input_date/time_format ')
In this UNIX example, slashes are separators in the date portion of the input
data, and colons are separators in the time portion:
