I am using Spring Data Neo4j and I have a repository like this:
public interface MyNeo4jRepository extends Neo4jRepository<Object, Long> {
#Query("with ['X', 'Y','Z'] as list_labels, "
+ "$appsFilter as appsList\n "
+ "MATCH (apps:) where apps.n IN appsList "
+ "MATCH (a)<-[:event]-(nodes) "
+ "WHERE any(x IN labels(nodes) WHERE x IN list_labels) "
+ "CALL apoc.path.expandConfig(nodes, { "
+ "relationshipFilter: 'R1|R2>',"
+ "labelFilter: '-l1|>l2',"
+ "maxLevel: 6,"
+ "endNodes: [apps],"
+ "uniqueness: 'NODE_PATH'}) YIELD path "
+ "unwind nodes(path) as n "
...
}
I want to create this query using conditions like this:
#Query("with ['X', 'Y','Z'] as list_labels, "
+ "$appsFilter as appsList\n "
+ "MATCH (apps:) where apps.n IN appsList "
+ "MATCH (a)<-[:event]-(nodes) "
+ "WHERE any(x IN labels(nodes) WHERE x IN list_labels) "
if (condition) + "WHERE ...." else + ""
+ "CALL apoc.path.expandConfig(nodes, { "
...
Is there a way to do it in the Neo4j query or do I have to do it with Spring composable repositories?
I think what you are looking for is the CASE construct
'WHERE ....'
+
CASE
WHEN condition1 THEN 'cypherFragement1'
WHEN condition2 THEN 'cypherFragement2'
ELSE 'cypherFragementElse'
END
+
.....
Maybe you can rewrite your entire cypher via apoc.do.when or apoc.do.case functions, which provide conditional judgment.

I am looking for some examples for apoc.cypher.doit use cases of all the parameters.
There is an example in the docs - https://neo4j.com/labs/apoc/4.2/overview/apoc.cypher/apoc.cypher.doIt/
(copying it here for reference)
MATCH (node)
WITH node, labels(node)[0] AS label
CALL apoc.cypher.doIt(
"WITH $node AS node
REMOVE node:" + label + "\n" +
"SET node:" + apoc.text.capitalize(toLower(label)) + "\n" +
"RETURN node",
{node: node})
YIELD value
RETURN value;
I'm trying to extract Search queries by certain rules and I need to get Queries that contain one of the given strings:
" WHERE " +
" Impressions > " + IMPRESSIONS_THRESHOLD +
" AND AverageCpc > " + AVERAGE_CPC_THRESHOLD +
" AND Query CONTAINS_ANY ['for sale in', 'buy'] " +
" DURING YESTERDAY ");
But I'm getting error message (tryed different variations):
One of the conditions in the query is invalid. (file Code.gs, line 19)
Although it seems like I do everything according to Formal Grammar:
String -> StringSingleQ | StringDoubleQ
StringSingleQ -> '(char)'
StringDoubleQ -> "(char)"
StringList -> [ String (, String)* ]
If I do just 1 string it works fine:
" WHERE " +
" Impressions > " + IMPRESSIONS_THRESHOLD +
" AND AverageCpc > " + AVERAGE_CPC_THRESHOLD +
" AND Query CONTAINS 'for sale in' " +
" DURING YESTERDAY ");
IIRC, the CONTAINS_ANY operator only works when you are filtering on labels. I'm not sure if this constraint is actually documented, but this article seems to at least imply it.
I've wrote this query that normally works
String query2 = "PREFIX publ: <http://www.ps7-wia2.com/publications/>\n" +
"PREFIX pub: <http://www.ps7-wia2.com/publications#>" +
"DELETE { publ: " + id + " pub:like ?o }\n" +
"INSERT { publ: " + id + " pub:like " + nbLikes + " }\n" +
"WHERE {publ:" + id + " pub:like ?o .}\n";
RDFConnection conn2 = RDFConnectionFactory.connect(DATABASE);
QueryExecution qExec2 = conn2.query(query2) ;
conn2.close();
qExec2.close();
And when I execute I encounter this error
org.apache.jena.query.QueryParseException: Encountered " "delete" "DELETE "" at line 2, column 52.
Was expecting one of:
"base" ...
"prefix" ...
"select" ...
"json" ...
"describe" ...
"construct" ...
"ask" ...
```
In SPARQL, query and update are parsed separately; they are separate languages which use many of the same elements but have different syntax for their functionality ("SELECT" vs "INSERT" etc).
Use update(...).
I am trying to use Google Adwords Reporting HTTP POST request to retrieve stats for a list of keywords that could exist under multiple Campaigns/Adgroups. This is the API documentation that I was referring to https://developers.google.com/adwords/api/docs/guides/reporting#prepare-the-http-post-request.
Below is scala code that returns 400 error code. What am I doing wrong ? Or is there another way of retrieving data from KEYWORDS_PERFORMANCE_REPORT report type ?
val httpClient = new DefaultHttpClient()
val postRequest=new HttpPost("https://adwords.google.com/api/adwords/reportdownload/v201605")
postRequest.addHeader("Host","adwords.google.com")
postRequest.addHeader("User-Agent", "curl, gzip")
postRequest.addHeader("Accept","*/*")
postRequest.addHeader("Expect","100-continue")
postRequest.addHeader("Accept-Encoding","gzip")
postRequest.addHeader("Content-Type","multipart/form-data; boundary=------------------------12d01fae60c7b559; charset=utf-8")
postRequest.addHeader("Authorization","Bearer 1/*************************************")
postRequest.addHeader("developerToken","/*************************************")")
postRequest.addHeader("clientCustomerId","/*************************************")")
postRequest.addHeader("Parameters","__rdxml: <?xml version=\"1.0\" " +
"encoding=\"UTF-8\"?>" +

" <reportType>CRITERIA_PERFORMANCE_REPORT</reportType>" +
" <dateRangeType>LAST_7_DAYS</dateRangeType>" +
" <downloadFormat>CSV</downloadFormat>" +
"</reportDefinition>")
val httpResponse=httpClient.execute(postRequest)
println(httpResponse.getStatusLine.toString)
Your report definition should go into the POST request's body encoded either as application/x-www-form-urlencoded or multipart/form-data—in your code you are adding it as a header called Parameters.
Here is my code:
if (amount != -1)
returnJson.Add("<p style=\"color: black;\">" + double.Parse(res_q.Replace(",", ".")) * amount + " " + res_i + "</p>");
else
returnJson.Add("<p style=\"color: black;\">" + res_q + " " + " ") + res_i + "</p>");
And no matter if the execution of the program goes to if or the else, if res_q="1,5", this returns 15 on server, and 1.5 locally.
Why is this happening?
The problem was in the comma.
I want to apply globalization in my program. Using CultureInfo.InvariantCulture was the answer I needed. Or simple replcing the comma with dot.
