asp_databases thread: Numeric variables in SQL WHERE clause in ASP

With your help, I was able to get the WHERE clause working for selecting
records where a field was equal to a text variable. But now I need to
select records where a field is equal to a numeric variable from another
database. Logically, here's what I want:
I = dbname1.fields(2) 'which is a long integer
SELECT * FROM dbname2 WHERE field_name = I
I get "not enough parameters," so I guess the variable name "I" needs some
kind of help in being interpreted. Can you help?
By the way, I also need to select on a date field, so I'll probably need
help with that, too.

I don't really understand what you're asking. If you are query a field that
is numeric, then the following will work:
strInt = 5
strSQL = _
"SELECT * " & _
"FROM table1 " & _
"WHERE SomeNumericField = " & strInt
Response.Write(strSQL)
If you need to query a date field you need to put # around it (for Access),
or ' around it (for SQL Server).
You might want to also look at this page:

I suggest you Response.Write(strSQL) so you can see exactly what you are
trying to send to the database.
Cheers
Ken

Hi,
Pls use the following if you are trying to query SQL
database from an ASP page.
I = dbname1.fields(2) 'which is a long integer
conn.execute("SELECT * FROM dbname2 WHERE field_name="
& I)
pls let me know if it worked.
Regards

I would not have believed that it could be that simple! I guess it's the
old "thinking outside the box" problem. I always assumed that all the
parameters for the WHERE clause had to be within the quote marks. Yet it
is not so. Thanks for the help...it worked perfectly.
What amazes me is that my 800+ page "Beginning ASP Databases" book never
mentions the use of variables in a WHERE clause.
