[ASP3]Cannot connect to database 2nd time
I have a page that connects to an Access database successfully, displaying all the rows on the page. However, if I hit refresh, I get an error on the line number where I'm opening the connection to the database. If I wait a while, it works.
I have another page that displays a subset of data from the same table and it also shows an error for the line number where the connection is opened. If I am on the page that shows the whole table, and click a link to go to the subset table, I will get the error. The same is true the other way around. If I wait a while between opening pages that use the table, the page connects as it should. I close both my connection and recordset and set both of these to Nothing at the end of the document. What causes me to not be able to connect a second time without waiting? I am new to ASP, so I hope this doesn't sound stupid. It is hopefully some easy thing I am missing, and hopefully my description may be enough so someone here can tell me what I should do or what topic to read up on! Thanks, all! |

common practice for accessing databases is to close the connection as soon as possible.
If you close your connection at the end you can get the following situation: opening connection -> get data -> click on link for sub-table/refresh -> tries to open connection -> error why? because the connection to that database is already open. (and locked). After a while the connection will time out, and you can open it again (as you experienced) a better way instead of setting the standard time-out to a shorter period would be: opening connection -> get data -> close connection -> click link for subtable/refresh -> open connection -> get data -> close connection. Now maybe for an access db this kind of practice isn't -that- important, but as soon as you're using bigger multi-user db's, things like this will get quite important.
