I. Table structure definition:
----Table Name: Product
----Table Name: Product
----Field Name: Product No.: PRODUCT_ID
----Product Name: Product_Name
Two. Function Description:
----User enter a product number, you do not need to enter a full name. Fuzzy Query method. Find a record that satisfies the criteria.
----User enter a product number, you do not need to enter a full name. Fuzzy Query method. Find a record that satisfies the criteria.
Three. Program Script
----The entire program has three ASP files (omitting the HTML language section)
----The entire program has three ASP files (omitting the HTML language section)
----1 user query data entry form: input. Asp
-----User Input Product number
< Form method= "Post" action= "/cgi/prod.asp" >
< Input type= "Text" name= "Id" size= ">
< Input type= "Submit"
Value= "Submit" name= "B1" >
</form >
2. One of the paging processing procedures: prod.asp
Trigger----user submits form input.asp
<%cid=trim (Request.Form ("Id")% >
<%set RLT = CreateObject ("Adodb.recordset")% >
Creating a Recordset object
<%sql= "Select * from Product Where product_id like '
"& Cid &" ' + '% ' ">
<%rlt.open Sql, "uid=ncgi; pwd=sql;dsn=tcgi ", 1% >
Execute SQL statement
<% If rlt.pagecount< 1 Then% >
< H2 > No record </H2 >
< A href= "Javascript:History.Back ()" >
Back < a >
<%else% >

The following display query information: Display style:
Total xx page XXX Records page No.: 1.2.3. 4.5...
Total <%=rlt.pagecount% > page
<%=rlt.recordcount% > Records
Page number:<% I=1 to rlt.pagecount% >
<%CID=RLT ("product_id")
< ahref= "Prodpage.asp?" pcnt=<%=i% >&id=<%=cid% > >
<%=i% >.</a >
<%next% >
< a >
< Hr >
<%rlt.pagesize=20% >
The following display product list: Display style:
1.XXXX
2.XXXX
****** ...........
<%rlt.absolutepage=1% >
<% for I=1 to rlt.pagesize% >
<% If Rlt.eof Then
Exit for
End if% >
< Li ><%=i%. <%=trim (RLT ("Product_Name")) </li >
<%rlt.movenext
next% >
<%rlt.close% >
3. Paging Process two: propage.asp
----User Selection (page number: 1.2.3.) 4.5.......) Trigger after a page number in
<%cid=trim (Request.QueryString ("Id")% >
<%rlt.absolutepage=request.querystring ("pcnt")% >
The above part is identical with prod.asp * * *
<% for I=1 to rlt.pagesize% >
<% If Rlt.eof Then
Exit for
End if% >
< Li ><%=i%. <%=trim (RLT ("Product_Name")) </li >
<%rlt.movenext
next% >
<%rlt.close% >
Four. Supplementary notes;
----You can have the user set the length of each page. The method is to use the session object to maintain user information to accept user settings information:
----You can have the user set the length of each page. The method is to use the session object to maintain user information to accept user settings information:
<%session ("size") =request.form ("size")% >
Replace the prod.asp <%rlt.pagesize=20% > sentence with the following statement
<%if session ("size") = "" Then
Rlt.pagesize=20
Else
Rlt.pagesize=session ("size")
End if% >
Difficult to resolve
1. The key to paging function:
Application of Pagesize AbsolutePage attribute
Pagesize: per page record size
AbsolutePage: The cursor navigates to that page. For example, there are 20 records, divided into two pages, each page 10
Absolutepage=1 begins with the first record.
The absolutepage=2 begins with the 11th record.
2.<%rlt.open Sql, "uid=ncgi; pwd=sql;dsn=tcgi ", 1% >
DSN: System Data Source Name, Uid: User name, PWD: User password, 1: Cursor type
You must be in the Control Panel-->
Set up system data source in 32-bit ODBC, remember the system data source
Rather than a user data source
Cursor Type: 0, is the default value, but if you want to implement the paging function the cursor type must be set to 1
Otherwise Recordcount Pagesize PageCount properties are not available.
3.request.form ("id") and request.querystring ("id")
The name is ID
Request.QueryString ("id") refers to accepting data from a URL
