I have azure table with following properties
event_name (string)
event_date_time (dateTime)
status (string)
From logic app I need to fetch all records which satisfies following condition
current time <= event_date_time <= current_date_time + 24 hours
I am using logic Get Entities connector . I am not sure how to implement above logic .
Is there any date difference function which will return difference in hours ?
Similar solution with your another post, just use "Filter Query" like below:

I need your help to solve a technical problem in ADF Dataflow.
data
my_dataflow
I need to merge rows where the dates cross or touch each other. The problem is that I can't manipulate a variable to increment in dataflow to get the following result (in yellow).
This result would allow me to group the rows together.
I don't know how implement it into dataflow
The logic will be :
CASE(nrow == 1, my_variable = 1,
endDate > startDate-1 || endDate == startDate-1,my_variable,
my_variable + 1
)
Do you have a solution to work around this problem?
I want to find events that are a on now and upcoming (next 30 days) but that are also not in the past.
When i run this as a cloud function, I get "Cannot have inequality filters on multiple properties". How am I meant to get this type of data.
(ignore the fact that the date stuff is a bit messy, am still playing around).
// Create date 30 days in future
const searchData: Date = new Date();
searchData.setDate(searchData.getDate() + 30);
// Load data and handle empty respoonse
const response: admin.firestore.QuerySnapshot = await admin
.firestore()
.collection(Collections.EVENTS)
.where("startDate", "<=", admin.firestore.Timestamp.fromMillis(searchData.valueOf()))
.where("endDate", ">=", admin.firestore.Timestamp.fromMillis(new Date().valueOf()))
.where("public", "==", true)
.limit(NUMBER_OF_EVENTS)
.get();
Edit:
I would like to know the data structure/query method that will allow me to return all events in the events collection that are on now or that will start in the next month. Additionally, I would like the query to exclude events that have already finished. Each document (event) has a startDate and endDate timestamp on it.
Since you have two fields to check with ranges, I'm not sure this is doable with a single query. What you can do instead is perform two queries, merge the results on the client, and perform a final filter to get the exact matches.
Make an assumption about the maximum duration for an event. Call that amount of time "X".
Query for all documents where startDate is greater than now - X, and also less than now + 30 days. Call this result set "A".
Query for all documents where endDate is greater than now, and also less than now + 30 days. Call this result set "B".
On the client, iterate all the results from A and B, checking to see if the start and end dates fit the criteria you want.
I can't think of a way to structure your data that will do this with a single query.
I know this is kind a old thread, but the answer might be good for others.
What you can do as I at the end ended up doing, is that you have a $start_date and a $target_date.
You then do like this:
<?php
$start = strtotime('2021-11-22');
$target = strtotime('2022-01-01 0:00:00');
$limit = (($target - $start) / 86400);
$query = $col_data->where('date.day_start', '>=', $start);
$query = $query->limit($limit);
?>
Not bad, eh? You welcome!
From the docs:
You can only perform range comparisons (<, <=, >, >=) on a single field, and you can include at most one array-contains or array-contains-any clause in a compound query:
citiesRef.where("state", ">=", "CA").where("state", "<=", "IN");
citiesRef.where("state", "==", "CA").where("population", ">", 1000000);

I have document contains properties like this
{
"id":"1bd13f8f-b56a-48cb-9b49-7fc4d88beeac",
"name":"Sam",
"createdOnDateTime": "2018-07-23T12:47:42.6407069Z"
}
I want to query a document on basis of createdOnDateTime which is stored as string.
query e.g. -
SELECT * FROM c where c.createdOnDateTime>='2018-07-23' AND c.createdOnDateTime<='2018-07-23'
This will return all documents which are created on that day.
I am providing date value from date selector which gives only date without time so, it gives me problem while comparing date.
Is there any way to remove time from createdOnDateTime property or is there any other way to achieve this?
CosmosDB clients are storing timestamps in ISO8601 format and one of the good reasons to do so is that its lexicographical order matches the flow of time. Meaning - you can sort and compare those strings and get them ordered by time they represent.
So in this case you don't need to remove time components just modify the passed in parameters to get the result you need. If you want all entries from entire date of 2018-07-23 then you can use query:
SELECT * FROM c
WHERE c.createdOnDateTime >= '2018-07-23'
AND c.createdOnDateTime < '2018-07-24'
Please note that this query can use a RANGE index on createdOnDateTime.
Please use User Defined Function to implement your requirement, no need to update createdOnDateTime property.
UDF：
function con(date){
var myDate = new Date(date);
var month = myDate.getMonth()+1;
if(month<10){
month = "0"+month;
}
return myDate.getFullYear()+"-"+month+"-"+myDate.getDate();
}
SQL：
SELECT c.id,c.createdOnDateTime FROM c where udf.con(c.createdOnDateTime)>='2018-07-23' AND udf.con(c.createdOnDateTime)<='2018-07-23'

Hope it helps you.
I am trying to query the WadPerformanceCountersTable generated by Azure Diagnostics which has a PartitionKey based on tick marks accurate up to the minute. This PartitionKey is stored as a string (which I do not have any control over).
I want to be able to query against this table to get data points for every minute, every hour, every day, etc. so I don't have to pull all of the data (I just want a sampling to approximate it). I was hoping to using the modulus operator to do this, but since the PartitionKey is stored as a string and this is an Azure Table, I am having issues.
Is there any way to do this?
Non-working example:
var query =
(from entity in ServiceContext.CreateQuery<PerformanceCountersEntity>("WADPerformanceCountersTable")
where
long.Parse(entity.PartitionKey) % interval == 0 && //bad for a variety of reasons
String.Compare(entity.PartitionKey, partitionKeyEnd, StringComparison.Ordinal) < 0 &&
String.Compare(entity.PartitionKey, partitionKeyStart, StringComparison.Ordinal) > 0
select entity)
.AsTableServiceQuery();
If you just want to get a single row based on two different time interval (now and N time back) you can use the following query which returns the single row as described here:
// 10 minutes span Partition Key
DateTime now = DateTime.UtcNow;
// Current Partition Key
string partitionKeyNow = string.Format("0{0}", now.Ticks.ToString());
DateTime tenMinutesSpan = now.AddMinutes(-10);
string partitionKeyTenMinutesBack = string.Format("0{0}", tenMinutesSpan.Ticks.ToString());
//Get single row sample created last 10 mminutes
CloudTableQuery<WadPerformanceCountersTable> cloudTableQuery =
(
from entity in ServiceContext.CreateQuery<PerformanceCountersEntity>("WADPerformanceCountersTable")
where
entity.PartitionKey.CompareTo(partitionKeyNow) < 0 &&
entity.PartitionKey.CompareTo(partitionKeyTenMinutesBack) > 0
select entity
).Take(1).AsTableServiceQuery();
The only way I can see to do this would be to create a process to keep the Azure table in sync with another version of itself. In this table, I would store the PartitionKey as a number instead of a string. Once done, I could use a method similar to what I wrote in my question to query the data.
However, this is a waste of resources, so I don't recommend it. (I'm not implementing it myself, either.)
I have a search log with fields namely time, place and the query. I want to find the most queried word from a particular place between a particular time. All the fields namely date,time, query_String are chararrays. I have the below pig script but it doesnot do what is required.
Data = LOAD 'data' USING CustomPigStorage();
FClients = FILTER Data BY NOT(country is null);
Clients = FOREACH FClients GENERATE date,time, country,query_string as query;
grp = group Clients by (query, country, date, time);
wth_count = foreach grp generate FLATTEN(group), COUNT(Clients) as count;
For example, I want the result to be "between 2pm and 3 pm, hello was searched 4 times from USA".
I am basically confused by the Count() function .Relatively new to pig. I believe my count() here is counting the total number of records I have.
Your query looks correct, COUNT(Clients) returns number of records in the bag, that came from Clients and belong to the group. To see it you can remove COUNT from "wth_count" statement and save results into a file and than look into it.
wth_count = foreach grp generate group, Clients;
store wth_count into 'path';
Your potential problem might be in the fact that you are using date and time columns in the group by and they produce too many groups. To mitigate this you could write a java static function that gets date and time and returns a single value for the range, for example 12-07-2012, 14.05.03 is converted into "12-07-2012 14h" and 12-07-2012, 14.05.05 into "12-07-2012 14h". This will create a key that covers the time interval 2pm and 3pm and will put all of the records from Clinets into that group's bag.
