What is the simplest way to query a WSS/MOSS list from a remote client
Using /_vti_bin/lists.asmx and XML fragments for the query seems to be a large chunk of work for a simple task?
I have found the U2U CAML Query Builder which helps a bit
If you write in .NET, reference Microsoft.SharePoint.Dll, get an instance of SPWeb and through that an instance of your list. Then you can access it directly, or create a CAML query through defining an SPQuery q, setting the CAML query string to q.Query and getting the SPListItemCollection col = list["myList"].GetItems(q);
I found the solution - Linq for Sharepoint how cool is that!

It's not finished, but what it has is fine for me

I'm using the Java library to connect to Big Query and get data. I'd like to display back to the user what the final SQL was, with its positional parameters inserted. Is that possible? I've looked through the QueryJobConfiguration Builder api and in some other classes, but I couldn't find anything.
I am developing a website for my company, that allows users to query a database in order to get the information they need.
Currently, the users are used to a particular form of queries, and I don't want to make them change the way they are used to. Therefore, I need to convert their query to Lucene's query syntax.
There are some cases which I'm not sure what is the best way to implement them using Lucene syntax, I was wondering maybe you have some better ideas:
"Current Query" : serverRole=~'(ServerOne|ServerTwo|ServerThree)'
"Lucene Suggested": (serverRole:*ServerOne* OR serverRole:*ServerTwo* OR serverRole:*ServerThree*)
Take into account that I'm using Regex to convert these queries, so one of the difficulties I'm facing for example, is how to do it if the number of elements (ServerOne|ServerTwo|ServerThree.....) is dynamic:
luceneQuery = currentQuery
.replace(/(==~|=~)('|")([a-zA-Z0-9]+)(\|)([a-zA-Z0-9]+)('|")/g, ':*$3 OR $5*')
Another query for example:
"Current Query" : OS=~'SLES1[12]'
"Lucene Suggested": (OS:*SLES11* OR OS:*SLES12*)
I would recomand you to check BooleanQuery() on Lucene to create more complex queries like Wildcard , Term, Fuzzy U can include all by using Occur parameter while u build your queries. As an example
Query query1 = new WildcardQuery(new Term("contents", "*ServerOne*"));
Query query2 = new WildcardQuery(new Term("contents", "*ServerTwo*"));
BooleanQuery booleanQuery = new BooleanQuery.Builder()
.add(query1, BooleanClause.Occur.SHOULD)
.add(query2, BooleanClause.Occur.SHOULD)
.build();
There is also regex queries you can directly run but when your indexed field will be complicates it taking time to find regex match
I have some MySQL code that looks like this:
SELECT
visitor AS team,
COUNT(*) AS rg,
SUM(vscore>hscore) AS rw,
SUM(vscore<hscore) AS rl
FROM `gamelog` WHERE status='Final'
AND date(start_et) BETWEEN %s AND %s GROUP BY visitor
I'm trying to translate this into a Django version of that query, without making multiple queries. Is this possible? I read up on how to do Sum(), and Count(), but it doesn't seem to work when I want to compare two fields like I'm doing.
Here's the best I could come up with so far, but it didn't work...
vrecord = GameLog.objects.filter(start_et__range=[start,end],visitor=i['id']
).aggregate(
Sum('vscore'>'hscore'),
Count('vscore'>'hscore'))
I also tried using 'vscore>hscore' in there, but that didn't work either. Any ideas? I need to use as few queries as possible.
Aggregation only works on single fields in the Django ORM. I looked at the code for the various aggregation functions, and noticed that the single-field restriction is hardwired. Basically, when you use, say, Sum(field), it just records that for later, then it passes it to the database-specific backend for conversion to SQL and execution. Apparently, aggregation and annotation are not standardized in SQL.
Anyway, you probably need to use a raw SQL query.
i want to group the output i am getting through date type. But i am storing the data in solr using datetime type. Date Format i am using is
Date format :: "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
For e.g. Date is stored in solr as "2013-03-01T20:56:45.000+00:00"
What i want as output is count of dates :: for .e.g.
Date1:: "2013-03-01T20:56:45.000+00:00"
Date2:: "2013-03-01T21:56:45.000+00:00"
Date3:: "2013-03-01T22:56:45.000+00:00"
Date3:: "2013-03-02T22:56:45.000+00:00"
Date4:: "2013-03-02T23:56:45.000+00:00"
So i want the output as two columns ::
Date Count
2013-03-01 3
2013-03-02 2
Here is the code i am using
String url = "http://192.168.0.4:8983/solr";
SolrServer server = new HttpSolrServer(url);
SolrQuery query = new SolrQuery();
query.setQuery("*:*");
query.addFilterQuery("sessionStartTime:[2013-03-01T00:00:00Z TO 2013-03-04T24:00:00Z]");
query.add("group", "true");
query.add("group.field","uniqueId"); // uniqueId is grouping the data
query.add("group.main","true");
query.setRows(9999);
QueryResponse rs=server.query(query);
Iterator<SolrDocument> iter = rs.getResults().iterator();
Help is appreciated.
I know that this is an older question but I am working on something related to this so I thought I would share my solution. Since you are using grouping, rs.getResults() will likely be null. After reading through the SolrJ API and doing some testing on my end, you will find that the results are indeed grouped as you want them to be. To access them, create a variable like such:
List<Group> groupedData = rs.getGroupResponse().getValues().get(0).getValues()
Note that Group is the class org.apache.solr.client.solrj.response.Group
Then, iterate through groupedData, usinig groupedData.get(i).getResult() to get a SolrDocumentList of results for each grouped value. In your example, (assuming the data is ordered as you said it would be), groupedData.get(0) would give you a SolrDocumentList of the three matches that have the date 2013-03-01.
I understand that this is quite the chain of method calls but it does end up getting the results to you. If anyone does know a faster way to get to the data, please feel free to let me know as I would like to know as well.
Refer to the API for GroupResponse for more information
Note that this answer is working on Solr 5.4.0
The output that you are trying to achieve, I believe is better suited to Faceting over grouping. Check out the documentation on Date Faceting more specifically and SolrJ fully supports faceting, see SolrJ - Advanced Usage. For an introduction to Faceting I would recommend reading Faceted Search with Solr
Sitecore reference talk about some attributes you can use in Query, including ##templatename, ##id and ##parentid etc.
parentid doesn't seem to work - /sitecore/content//*[##parentid!=''] never returns any result. While /sitecore/content//*[##templatename!=''] works fine. Sitecore version is 6.5 and 6.6.
Has anyone been able to query with ##parentid? ( Perhaps it uses Ancestor/Descendant table and I'm missing data?? - just a guess )
It is attempting to parse the value as a GUID and failing. Instead, try an empty GUID like so:
/sitecore/content//*[##parentid!='{00000000-0000-0000-0000-000000000000}']
##parentid only works in fast query.
In fast query you can only use ancestor not ancestor-or-self (which doesn't give an error it just does a fallback too ancestor).
Also you can't use the pipe | in fast query to concatenate results of 2 or more queries.
I can't for the life of me figure out how to do a "give me the ancestor-or-self of the current node whose parent has id={110D559F-DEA5-42EA-9C1C-8A5DF7E70EF9}.
