Issue
If you run the following query, it will throw RepositoryException from getNodes().
Sample code:
Session session = resourceResolver.adaptTo(Session.class);
QueryManager queryManager = session.getWorkspace().getQueryManager();
String queryString = "SELECT child.*, page.[cq:lastReplicated] FROM [cq:PageContent] AS page "
+ "INNER JOIN [nt:unstructured] AS child ON ISCHILDNODE(child,page) "
+ "WHERE ISDESCENDANTNODE(page,'/content/geometrixx/en/') ";
Query query = queryManager.createQuery(queryString, Query.JCR_SQL2);
QueryResult result = query.execute();
NodeIterator nodes = result.getNodes();
Exception:
javax.jcr.RepositoryException: Query contains more than one selector: [child, page] at org.apache.jackrabbit.oak.jcr.query.QueryResultImpl.getNodes(QueryResultImpl.java:161)
API Reference:
https://docs.adobe.com/content/docs/en/spec/javax.jcr/javadocs/jcr-2.0/javax/jcr/query/QueryResult.html#getNodes()
RepositoryException - if the query contains more than one selector
Environment
AEM
Cause
As the query contains more than one selector, you need to specify the selector (e.g. child or page).
Resolution
Use the getRows method instead of getNodes.
Query query = queryManager.createQuery(queryString, Query.JCR_SQL2);
QueryResult result = query.execute();
RowIterator rows = result.getRows();
while (rows.hasNext()) {
Row row = rows.nextRow();
Node node = row.getNode("page");
}
