Hi,

I am trying to retrieve records from my Access database.
I want to retrieve those records whose zip = zipcode (from a form)
or if that perticular zipcode is not present than find for a nearest zip code to display the record.

select * from table where country = '" + cstr(trim(Request("country"))) + "' and zip='" + cstr(trim(Request("zipcode"))) + "' or zip= "nearest zipcode query"

How to write a query on such selection

Can anybody help me out.

Hi,
I do not know if what I will say will help or not but try
You can use the wildcard operators to get the nearest zipcode.
your statement will be
select * from table where country = '" + cstr(trim(Request("country"))) + "' and zip='" + cstr(trim(Request("zipcode"))) + "' or ziplike 'Br%'

Examples:

Like 'Br%' This will retrieve every zipcode begining with the letters Br
Like 'BR%' This will retrieve every zipcode begining with the letters BR
Like '%een' This will retrieve every zipcode ending with the letters een
Like '%en%' This will retrieve every zipcode containing the letters en
Like '_en' This will retrieve every 3 letter zipcode ending in the letters en
Like '[ck]%' This will retrieve every zipcode beging with the letters c or k
Like '[s-v]ing' This will retrieve every zipcode ending in letters ing and begining with any single letter from s to v
Like 'M[^c]%' This will retrieve every zipcode begining with the letters M that does not have the letter c as the secvond letter

see the above are examples, you may adjust it to suit your needs

Try this :

[code]
sql = " SELECT TOP 1 *, ABS(CONVERT(INT,zip) - "
sql = sql & CLng(trim(Request("zipcode"))) + " ) AS 'diff' "
sql = sql & " FROM table "
sql = sql & " WHERE country = '" & cstr(trim(Request("country"))) & "' "
sql = sql & " ORDER BY diff ASC "
[/code]

Final sql should look like this:

[code]
SELECT TOP 1 *, ABS(CONVERT(INT,zip)- 90000 ) AS 'diff' FROM table
WHERE country = 'USA' ORDER BY diff ASC
[/code]
assuming Request("country") = "USA" and Request("zip") = "90000"

Hi Vanith,

I tried the same way, but it says 'undefined function "CONVERT" in expression'. And one more thing that, I have set the datatype for zip as Text in my table, should I change it to some othere data type?

Please help me ASAP.

Ooops! My mistake.. I didn't notice that you are using an Access database. that would work good in SQL server. Here's the equivalent SQL script for Access.

asp code:
[code]
sql = " SELECT TOP 1 *, ABS(CLng(zip) - "
sql = sql & CLng(trim(Request("zipcode"))) + " ) AS diff "
sql = sql & " FROM table "
sql = sql & " WHERE country = '" & cstr(trim(Request("country"))) & "' "
sql = sql & " ORDER BY "
sql = sql & " ABS(CLng(zip) - " & CLng(trim(Request("zipcode"))) & " ) ASC"
[/code]


The actual query would look like
[code]
SELECT TOP 1 zip, country, Abs(CLng([zip])-07311) AS diff
FROM Table
WHERE country='US'
ORDER BY Abs(CLng(zip)-07311);
[/code]

: Here nearest zip code means, if I enter 12234, & this zipcode is not present then, I want to search 12235 else 12236 etc.. till it gets something like 12241...
