> Let's say I have field {{stringx}} declared in my schema but is empty (no docs in the index yet).
> Currently, the {{SolrSchema}} uses Luke to generate the table metadata and since {{stringx}} is empty, it's not included in the table metadata.
> {code}
> select id, stringx from collection
> {code}
> will fail with:
> {code}
> Error while executing SQL "SELECT id, stringx FROM collection1": From line 1, column 12 to line 1, column 18: Column 'stringx' not found in any table
> at org.apache.solr.client.solrj.io.stream.JDBCStream.open(JDBCStream.java:286)
> at org.apache.solr.client.solrj.io.stream.ExceptionStream.open(ExceptionStream.java:52)
> {code}
> Of course, if an application uses JDBC and {{describe table}} then they won't see {{stringx}} so no harm no foul. However, some apps / users may know that {{stringx}} is a field in the schema, leading to some mismatch in expectations and results.
