[teiid-issues] [JBoss JIRA] Commented: (TEIID-177) Provide JDBC 3.0 JRE 1.5 backwards compatibility

[Steve Hawkins (JIRA)]

    [ https://jira.jboss.org/browse/TEIID-177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12537547#action_12537547 ] 

Steve Hawkins commented on TEIID-177:
-------------------------------------

I am now inclined to remove the comment based approach.  There are a couple of reasons for this.

1. with ODBC support there is another possible path of using a 1.5 (or older) client with the JDBC-ODBC bridge to call a Teiid 7.1.  The limitations here would be JDBC extensions and transaction support, but at least for local transactions support could be added (there is already a JIRA on the ANSI syntax, but we could just reuse the set statement logic to allow SET AUTOCOMMIT OFF|ON).  

2. The comment based approach will only allow us to get to 1.5, not 1.4 - which would probably be just as common of a legacy environment (just based upon our MetaMatrix customer experience).   Our client server code is littered with 1.5 constructs and cannot through simple commenting be reverted to 1.4 support. 

So we'll need to revisit what we really intend to support here, are we requiring a distribution jar, or would instructions on using retro tooling, or a workaround based on ODBC be sufficient.
