I found a way. To use LocalSession.State -----Original Message----- From: Anthony [mailto:[EMAIL PROTECTED] Sent: Thursday, October 26, 2006 3:58 AM To: [email protected]; [EMAIL PROTECTED] Subject: RE: Active connection
That ping query, specifically the "DUAL" part, is strictly for Oracle only Use an SQL92 standard query. This will work on Oracle, MS-SQL, and newer versions of MySQL as well. Of course if you have hundreds of tables, this query will lose performance. In that case you may need to derive a more efficient simple query. SELECT COUNT(1) FROM INFORMATION_SCHEMA.TABLES But I think the original post will not even get that far. He has lost DB connection, so he definitely will not be able to run a query and an exception will be thrown. I am too new to iBatis, but if there isn't one, there should be a ConnectionState property to determine state of the connection. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Larry Meadors Sent: Wednesday, October 25, 2006 7:25 AM To: [email protected] Subject: Re: Active connection You'll need to use a ping query to make sure that the connection is valid.
