I'm starting to learn Power BI and metrics with DAX and some help will be apreciated, please. I would need to know how, in a sorted table (by ID, Modification and Date), of data already defined by fields ([ID, Modification, Fecha(=Date), V_INICIAL, V_FINAL, RESULT]), I can compare values of different rows and columns, regardless of the number of iterations. My objective is to calculate a measure that returns the Number of different IDs per type of Modification, which meet the "OK" Result. This result compares, for each value of the Modification field, the value of the V_INITIAL of the first iteration, with the value of the V_FINAL of the last iteration, of the Modification. And if both values are different, the Result is "OK", since the modification has been made. Otherwise it is "NOT_OK" because there is no modification. Thank you very much for help! ;)Table
This calculated column works with your example data (where [Mod] is the [Modificación]-column):
N.B. This is by no means an optimised code. I tried to keep it as simple and easy to understand as possible.
Resultado =
var current_ID = [ID]
var current_mod = [Mod]
var maxDate =
CALCULATE(
MAX('DataTable'[Fecha]);
FILTER(
ALL('DataTable');
'DataTable'[ID] = current_ID && 'DataTable'[Mod] = current_mod
)
)
var minDate =
CALCULATE(
MIN('DataTable'[Fecha]);
FILTER(
ALL('DataTable');
'DataTable'[ID] = current_ID && 'DataTable'[Mod] = current_mod
)
)
var initialState =
CALCULATE(
MAX('DataTable'[v_inicial]);
FILTER(
ALL('DataTable');
'DataTable'[Fecha] = minDate && 'DataTable'[ID] = current_ID && 'DataTable'[Mod] = current_mod
)
)
var finalState =
CALCULATE(
MAX('DataTable'[v_final]);
FILTER(
ALL('DataTable');
'DataTable'[Fecha] = maxDate && 'DataTable'[ID] = current_ID && 'DataTable'[Mod] = current_mod
)
)
return
SWITCH(
TRUE();
[Fecha] = maxDate && initialState <> finalState; "OK";
[Fecha] = maxDate; "Not_OK";
BLANK()
)

I want to create a measure that return distinctcount(ordernumbers) where every row is "Sant" Divided by the distinctcount(ordernumbers).
The measure should adapt the calculation by chosen filter.
This is my temporary solution which doesn't adapt when I am applying filters.
Availability =
VAR __CountSIRowsPerOrder =
COUNTROWS(
FILTER(
ALL(Sheet1);
[Ordernumber] = EARLIER([Ordernumber]) &&
[Available] = True))
VAR __CountRowsPerOrder =
COUNTROWS(
FILTER(
ALL(Sheet1);
[Ordernumber] = EARLIER([Ordernumber])))
RETURN
IF(__CountRowsPerOrder = __CountSIRowsPerOrder; True; False)
FilterAvailability (measure) =
CALCULATE(
DISTINCTCOUNT(Sheet1[Ordernumber]);
FILTER(Sheet1;[Availability] = True))
/
DISTINCTCOUNT(Blad2[Ordernumber])
I want to make a GL-Category Sequence like document sequence for every cash journal.
I added a field in cash journal window called journal number.
I want to generate a number for every cash journal and increment it by 1?
The document sequence is managed by the PO.java class in ADempiere. To use it, you need to add a column with the column name "DocumentNo" to your table. You will need to add the entry in the Sequence table to keep track of the numbers.
Here is the code from PO.java which is run when the record is first saved.
// Set new DocumentNo
String columnName = "DocumentNo";
int index = p_info.getColumnIndex(columnName);
if (index != -1 && p_info.getColumn(index).ColumnSQL == null)
{
String value = (String)get_Value(index);
if (value != null && value.startsWith("<") && value.endsWith(">"))
value = null;
if (value == null || value.length() == 0)
{
int dt = p_info.getColumnIndex("C_DocTypeTarget_ID");
if (dt == -1)
dt = p_info.getColumnIndex("C_DocType_ID");
if (dt != -1) // get based on Doc Type (might return null)
value = DB.getDocumentNo(get_ValueAsInt(dt), m_trxName, false, this);
if (value == null) // not overwritten by DocType and not manually entered
value = DB.getDocumentNo(getAD_Client_ID(), p_info.getTableName(), m_trxName, this);
set_ValueNoCheck(columnName, value);
}
}
I have this LINQ in C#, which I have to convert to a SQL query. And I am not sure how to do multiple filtering based on conditions:
var geofenceReport = companyContext.GeofenceSimpleReports.Where(x => x.EnterTime != null && x.ExitTime != null && x.MinutesInGeofence != null).AsQueryable();
if (model.GeofenceId != -1)
{
geofenceReport = geofenceReport.Where(x => x.iGeofenceId == model.GeofenceId).AsQueryable();
}
if (model.AssetId != -1)
{
geofenceReport = geofenceReport.Where(x => x.iAssetId == model.AssetId).AsQueryable();
}
if (model.CategoryId != -1)
{
geofenceReport = geofenceReport.Where(x => x.iCategoryId == model.CategoryId).AsQueryable();
}
if (model.SiteId != -1)
{
geofenceReport = geofenceReport.Where(x => x.iSiteId == model.SiteId).AsQueryable();
}
geofenceReport = geofenceReport
.Where(x => x.EnterTime >= model.StartDateTime &&
x.EnterTime <= model.EndDateTime)
.AsQueryable();
So this is what I came up with in SQL:
I created a new type for AssetId:
USE myDatabase
GO
CREATE TYPE idTable AS TABLE (id INT)
And then in SQL:
USE myDatabase
GO
CREATE PROCEDURE [dbo].[xPT_GetGeofenceSummaryReport]
#iAssetIds idTable,
#iGeofenceId INT,
#iCategoryId INT,
#iSiteId INT,
#iAssetId INT
AS
IF #iAssetId != -1
SELECT * FROM GeofenceSimpleReport WHERE iAssetId in (#iAssetIds)
IF #iGeofenceId != -1
SELECT * FROM GeofenceSimpleReport where iGeofenceId = #iGeofenceId
IF #iCategoryId != -1
SELECT * FROM GeofenceSimpleReport where iCategoryId = #iCategoryId
IF #iSiteId != -1
SELECT * FROM GeofenceSimpleReport where iSiteId = #iSiteId
and this GeofenceSimpleReport is a database view.
But this will not work as it is logically wrong. This will 4 separate selects from the GeofenceSimpleReport.
I need to have one read from GeofenceSimpleReport with all filters applied.
And I don't want to read this data temporarily into a TABLE/LIST in memory as there is a lot of data.
Is there a way to write this query dynamically like I am doing in LINQ?
You're thinking about this procedurally, and going through a series of if-statements, rather than approaching your view as a set of data that you can filter all at once.
You can filter on the original criteria related to EntryTime, ExitTime, etc., and then for each parameter for which you provide a filterable value (not -1) then make sure the Id matches that record in the table. Anything where you gave a -1 for the value will automatically make that AND statement true.
I do this sort of thing all the time by passing in nullable parameters - if they're non-NULL then I filter on them - otherwise they just evaluate to true and pass through.
USE myDatabase
GO
CREATE PROCEDURE [dbo].[xPT_GetGeofenceSummaryReport]
#iAssetIds idTable,
#iGeofenceId INT,
#iCategoryId INT,
#iSiteId INT,
#iAssetId INT
AS
SELECT *
FROM GeofenceSimpleReport
WHERE EnterTime IS NOT NULL
AND ExitTime IS NOT NULL
AND MinutesInGeofence IS NOT NULL
AND (#iAssetId = -1 OR iAssetId IN (#iAssetIds))
AND (#iGeofenceId = -1 OR iGeofenceId = #iGeofenceId)
AND (#iCategoryId = -1 OR iCategoryId = #ICategoryId)
AND (#iSiteId = -1 OR iSiteId = #iSiteId)
this is my original query
public UserChallenge GetUserChallenge(int userId, int challengeId)
{
var result = from userChallenge in DataContext.UserChallenges
where userChallenge.UserId == userId && userChallenge.ChallengeId == challengeId
select userChallenge;
here is the modified query
var result = from userChallenge in DataContext.UserChallenges
where userChallenge.ChallengeId == challengeId
select userChallenge;
there is more than 1 userChallenge's that hold that ChallengeId. How can I select only the first one ?
Check out FirstOrDefault.
var result = (from userChallenge in DataContext.UserChallenges
where userChallenge.UserId == userId && userChallenge.ChallengeId == challengeId
select userChallenge).FirstOrDefault();
But in the long run, it might be more helpful to determine a way to uniquely identify your records.
You can use First or FirstOrDefault to get the first item in the list. FirstOrDefault returns null if no item is found, whereas First fails with "Sequence contains no elements" error.
var result = (from userChallenge in DataContext.UserChallenges
where userChallenge.ChallengeId == challengeId
select userChallenge).FirstOrDefault();
Is there a online system which converts SQL - LINQ or can anyone else help convert the SQL - LINQ below?
SELECT MIN(startTime) As startTime, MAX(endTime) As endTime
FROM tblRA
LEFT JOIN tblA ON tblRA.asID = tblA.asID
WHERE 'xxxxxx' BETWEEN tblRA.startDate AND tblRA.endDate
AND tblA.availabilityDayOfWeek = 7
The main area I am having trouble is the .MAX/.MIN.
Heres what I have so far
public List<string> GetResourceAvailabilitiesByDate(DateTime searchDate)
{
DayOfWeek dayOfWeek = searchDate.DayOfWeek;
var minVal = from a in dc.tblResourceAvailabilities
join b in dc.tblAvailabilities on a.asID equals b.asID
where searchDate.Date >= a.startDate.Date && searchDate.Date <= a.endDate.Value.Date
&& b.availabilityDayOfWeek == (int)dayOfWeek
select b.startTime.ToShortTimeString();;
var maxVal = from a in dc.tblResourceAvailabilities
join b in dc.tblAvailabilities on a.asID equals b.asID
where searchDate.Date >= a.startDate.Date && searchDate.Date <= a.endDate.Value.Date
&& b.availabilityDayOfWeek == (int)dayOfWeek
select b.endTime.ToShortTimeString();
var min = minVal.Min(minVal.Min);
var max = maxVal.Max();
return min,max;
Thanks in advance for any help

I think your code is a little bit incorrect, and the first symptom of it is that you are using repeated code to define minval and maxval. I tried to simulate something similar to what you want and came to the following code, please adapt it to your needs.
public List<string> GetResourceAvailabilitiesByDate(DateTime searchDate)
{
DayOfWeek dayOfWeek = searchDate.DayOfWeek;
var vals = from a in dc.tblResourceAvailabilities
join b in dc.tblAvailabilities on a.asID equals b.asID
where searchDate.Date >= a.startDate.Date && searchDate.Date <= a.endDate.Value.Date
&& b.availabilityDayOfWeek == (int)dayOfWeek
select b;
var min = vals.Min(v => v.startTime).ToShortTimeString();
var max = vals.Max(v => v.startTime).ToShortTimeString();
return new List<string>() { min, max };
}
Some comments on your code, assuming it's C#.
You are trying to return an array of strings when you should be returning an array of dates.
Your where clause is pretty confuse. You're comparing the search date with startdate.Date and endDate.Value.Date. It does not make much sense.
Your select clause could select only b, or a, or whatever. You don't really need to select the date in it.
