----------------------------------
Summary: Aliases do not work for MongoDB modules
Key: METAMODEL-1088
URL: https://issues.apache.org/jira/browse/METAMODEL-1088
Project: Apache MetaModel
Issue Type: Bug
Affects Versions: 4.5.2
Reporter: Alberto
Priority: Minor
Queries containing aliases do not work properly for MongoDB modules. The
SelectItems of the returned dataset are not containing the aliases.
See below a unit test that is currently failing:
public void testSelectWithAlias() throws Exception {
if (!isConfigured()) {
System.err.println(getInvalidConfigurationMessage());
return;
}
DBCollection col = db.createCollection(getCollectionName(), new
BasicDBObject());
// delete if already exists
{
col.drop();
col = db.createCollection(getCollectionName(), new BasicDBObject());
}
final BasicDBObject dbRow = new BasicDBObject();
dbRow.append("name", new BasicDBObject().append("first",
"John").append("last", "Doe"));
dbRow.append("gender", "MALE");
col.insert(dbRow);
final MongoDbDataContext dc = new MongoDbDataContext(db, new
SimpleTableDef(getCollectionName(), new String[] {
"name.first", "name.last", "gender", "addresses",
"addresses[0].city", "addresses[0].country",
"addresses[5].foobar" }));
final DataSet ds1 = dc.executeQuery("select gender AS my_gender,
name.first AS my_name from my_collection where gender LIKE '%MALE%'");
final SelectItem[] selectItems = ds1.getSelectItems();
SelectItem firstSelectItem = selectItems[0];
SelectItem secondSelectItem = selectItems[1];
try {
assertNotNull(firstSelectItem.getAlias());
assertNotNull(secondSelectItem.getAlias());
} finally {
ds1.close();
}
}
