Close ADO-connection

Close ADO-connection

Postby Marc Vanzegbroeck » Sun Jul 14, 2013 8:51 pm

Hi,

I allways use in the beginning of my program
Code: Select all  Expand view
oSQL:=CreateObject("ADODB.Connection")
oSQL:ConnectionString:=ADO_SQL_Connectionstring
oSQL:Open()
...
...
 

and at the end
Code: Select all  Expand view
oSQL:close()
oSQL:=nil
 

and that is working very nice.

In a particual program I want to delete the SQLite-database and do

Code: Select all  Expand view
oSQL:close()
oSQL:=nil
ferase('.\myfile.db')

but the ferase() this returns an error -1
This mean that the file is not closed :(

I now if a only return recordsets, I don't need to open the file like that, but I need to execute some SQL-commands (like creating tables, and other commands)
How can I close the connection completely with ADO?

Thanks
Regards,
Marc

This is not needed.

Should be enough. It might be a timing issue. Try to insert a delay between close() and ferase().

Hi Marc

ferase requires the full path of the filename it may not be a sql issue.

Cheers

Colin,

This is not the problem, because it's working if I don't open the file before.

Enrico,

A delay between close() and ferase() don't work :( I even tested it with 10 seconds delay...

What did you use for the delay?

I wonder about other users having the database open thus preventing deletion. Is there a way to tell? Or, perhaps this is a temp file only created and used by one user?

I only use SQLite-database on stand-alone programs.
For network-versions I use MySQL. There I don't delete the database-file. Normaly I don't delete any database, but in this paricular program I want the user to be able to delete the SQLite-database, and create an other one...
