[jira] [Commented] (SOLR-9019) SolrJ JDBC - Ensure that R RJDBC works with SolrJ JDBC

["Kevin Risden (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SOLR-9019?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15250266#comment-15250266 ] 

Kevin Risden commented on SOLR-9019:
------------------------------------

Currently RJDBC is failing with the following error
{code}
Error in .jcall(rp, "I", "fetch", stride, block) : 
  java.lang.UnsupportedOperationException
Calls: dbGetQuery ... fetch -> fetch -> .local -> .jcall -> .jcheck -> .Call
{code}

This is caused by the following code in RJDBC
{code}
try { // run in a try since it's a hint, but some bad drivers fail on it anyway (see #11)
  rs.setFetchSize(fetchSize);
} catch (java.sql.SQLException e) { } // we can't use SQLFeatureNotSupportedException because that's 1.6+ only
{code}

This will require that ResultSetImpl implements setFetchSize or setFetchSize should throw a SQLException instead of UnsupportedOperationException.

> R has RJDBC (https://cran.r-project.org/web/packages/RJDBC/index.html) which can connect to JDBC. Check that it works with SolrJ JDBC.
