dateformat is ignored

sql server (alternate):
Hello,

I receive a file containing some character fields along with a date.
The date values in the file are formatted as "dd/mm/yy", that is
2-digit day, 2-digit month, and 2-digit year. The separator could be
slash or a dash ("-"). The file is in a proprietary format, and bcp is
not an option.

So, I decided to load the file using a prepared statement. I open a
cursor with an INSERT statement, read from the file, parse out values,
and put it in the database using the cursor. All is OK; except that
the date values are mangled. This is despite the fact that I am issuing
a "set dateformat dmy" before running the INSERT statement.

It seems that the "set dateformat dmy" is not being accepted, or it is
being ignored. I set it at the beginning right after opening a
connection to the database. From what I understand, it should work.
Am I doing something wrong? Any suggestions on how to get this to
work?

Thanks!

You say BCP isn't an option but you didn't explain what other method
you are using to read the file or why a cursor is necessary. Don't rely
on SET DATEFORMAT. Use the CONVERT function with the style parameter to
specify the exact format. Looks like style 3 or 103 is what you need.

I read from the file line by line and parse the line to extract the
fields. I then use the bound variables in the prepared Insert
statement to add it to the database. I wanted to change the DATEFORMAT
configuration as it seemed to be such a straight answer. I guess I
could use the CONVERT function if it is fast enough. I can do some
tests to see how it performs.

I am curius: is there a particular reason to shy away from setting
DATEFORMAT? Is it not reliable as implemented or something else?

Thanks a lot!

David and John,

Thank you very much for your input. I am now using the techniques that
you suggested and it works great!

Hi

If you are parsing a string then you constructing the date in CCYYMMDD
format will be a safe option.
