Database Display via GetString


Description : This page demonstrates the capabilities how to display a table from a SQL statement a very fast and scaleable way using a recordset method called GetString. GetString essentially asks the backend database to build a huge string instead of moving the data as rows and columns. It allows very limited specifications, basically what string to place between each column and row and how to display nulls. Notice the total absence of the traditional EOF loop. Its speed and scalability advantages are explained in: Http://www.learnasp.com/advice/whygetrows.asp This example does require ADO 2.0 or greater which can be downloaded from: http://www.microsoft.com/data If you are unsure which ADO version your server has http://www.learnasp.com/learn/versioncheck.asp will help you determine this. Does this approach matter for small data sets for example 9 rows x 2 columns of data? YES!!!!!!!! My site has SQLserver scripts that run like lightning. I once needed to fill a 9 item listbox from Access and got 90 sec script timeouts with movenext. Getstring never timed out. So in a real production situation it makes weak databases feasible and of course reduces the load on more industrial back-ends so maybe the SQLserver doesn't need as many indexes or RAM upgrades.
