Syntax error converting varchar to data type int

Dear experts,

  I'm creating a search and result page in ASP using Dreamweaver MX 2004.

The URL Paramter passed from the search.asp page is a varchar datatype.  

I attempt to create a recordset in result.asp page using Dreamweaver MX 2004's Add Recordset Server Beheavior and add a Variable in Variables list as follow:

Name           Default Value     Run-Time Value      
-------          ----------------    ---------------------
srchParm     3ABC12345        Request.QueryString("txt_search")


When I press Test button, Dreamweaver MX 2004 returns an error message: Syntax error converting varchar "3ABC12345" to data type int


My Question:

Why would Dreamweaver MX 2004 want to convert the value of the variable to int datatype??
When I leave Default Value blank, DW MX 2004 returns an error message saying the default value is missing and the recordset cannot be saved.

I need to be able to show the search result base on the searching parameter on the search.asp page.  How do I get it to work?

Thank you very much!!!

please show the sql query / procedure code that you use.
the error is in there.

typically, it happens when you are trying to append a varchar and a numerical data. sql server gives priority to the numerical data (why, i don't know, but it's like that), so you have to explicitely convert the numerical value to varchar:

this will fail with your error:
select 'ABC' + 1

this will work:
select 'ABC' + convert(1 as varchar)

I would prefer the PAQ with no points refunded, as the answer has been given IMHO... despite of the missing feedback of the questionner :-(
