I have a query result same as below:
var ptns = from p in db.Patients
select p;
This query returns a list of patients, but I need to filter the result based on DoctorNameID. The DoctorNameID should be in list of doctors as below:
List<string> listofDoctors = usrtodrs.Split(',').ToList();
I have searched a lot but I don't know how to do this. I have tested this query which doesn't work:
var ptns1 = from d in listofDoctors
join p in ptns.ToList() on d equals p.DoctorNameID
select p;
And also this query:
var ptns1 = ptns.ToList()
.Where(a => listofDoctors.Equals(a.DoctorNameID))
.ToList();
Any help?
You can use Contains extension and get the desired result.
var ptns1 = ptns.Where(x => listofDoctors.Contains(x.DoctorNameID)).ToList();
Refer the C# Fiddle with sample data.

Since two days I'm on a problem and I can't solve it so I come here to ask some help...
I have that bit of dax that basically take the path of a hierarchical table (integers) and take the string names of the 2 first in the path.
the names I use:
'HIERARCHY' the hierarchical table with names, id, path, nbrItems, string
mytable / addedcolumn1/2 the new table used to emulate the for loop
DisplayPath =
var __Path =PATH(ParentChild[id], ParentChild[parent_id])
var __P1 = PATHITEM(__Path,1) var __P2 = PATHITEM(__Path,2)
var l1 = LOOKUPVALUE(ParentChild[Place],ParentChild[id],VALUE(__P1))
var l2a = LOOKUPVALUE(ParentChild[Place],ParentChild[id],VALUE(__P2))
var l2 = if(ISBLANK(l2a), "", " -> " & l2a)
return CONCATENATE(l1,l2)
My problem is... I don't know the number of indexes in my path, can go from 0 to I guess 15...
I've tried some things but can't figure out a solution.
First I added a new column called nbrItems which calculate the number of items in the list of the path.
The two columns:
Then I added that bit of code that emulates a for loop depending on the number of items in the path list, and I'd like in it to
get name of parameters
concatenate them in one string that I can return and get
string =
var n = 'HIERARCHY'[nbrItems]
var mytable = GENERATESERIES(1, n)
var addedcolumn1 = ADDCOLUMNS(mytable, "nom", /* missing part: get name */)
var addedcolumn2 = ADDCOLUMNS(addedcolumn1, "string", /* missing part: concatenate previous concatenated and new name */)
var mymax = MAXX(addedcolumn2, [Value])
RETURN MAXX(FILTER(addedcolumn2, [Value] = mymax), [string])
Full table:
Thanks for your help in advance!
Ok, so after some research and a lot of try and error... I've came up to a nice and simple solution:
The original problem was that I had a hierarchical table ,but with all data in the same table.
like so
What I did was, adding a new "parent" column with this dax:
parent =
var a = 'HIERARCHY'[id_parent]
var b = CALCULATE(MIN('HIERARCHY'[libelle]), FILTER(ALL('HIERARCHY'), 'HIERARCHY'[id_h] = a))
RETURN b
This gets the parent name from the id_parent (ref. screen).
then I could just use the path function, not on the id's but on the names... like so:
path = PATH('HIERARCHY'[libelle], 'HIERARCHY'[parent])
It made the problem easy because I didn't need to replace the id's by there names after this...
and finally to make it look nice, I used some substitution to remove the pipes:
formated_path = SUBSTITUTE('HIERARCHY'[path], "|", " -> ")
final result
I have two tables: Kanji, and Vocabulary. Imagine the kanji table looks like this:
目
一
人
And the vocabulary table looks like this:
目的
一番目
一人
二人
人々
注目
目標
一匹
I want to generate a table that finds all vocabulary which contains the kanji in the kanji table and list them together. So the end result would look like this:
人 一人
二人
人々
一 一人
一番目
一匹
目 目的
一番目
注目
目標
I'm not sure how to go about this. If I have just one kanji, I can use the QUERY function to generate all of the vocabularies which contain that one kanji. But can I create a dynamic table which essentially inner joins the "kanji" and "vocabulary" tables, looking for every instance of "vocabulary" contains "kanji"?
I tried using a QUERY to combine the two tables, but it won't work because the tables are mismatched in size:
=QUERY({C1:C296,D1:D224}, "SELECT Col2 WHERE Col1 contains Col2")
In the above example, the C column / Col2 is vocabulary, the D column / Col1 is kanji.
Is there a way to do this using Google Sheets?
The simplest workaround is to get intersections by 1 value:
=FILTER(D:D;REGEXMATCH(D:D;"目"))
The picture shows how to use the copy of this function to get all intersections
The other approach is to use big array-formula like:
=TRANSPOSE(SPLIT(TEXTJOIN(",";1;TRANSPOSE(ARRAYFORMULA(IF(REGEXMATCH(A1:A8;TRANSPOSE(B1:B3));A1:A8;))));","))
=ARRAYFORMULA(SORT(TRIM(SPLIT(TRANSPOSE(SPLIT(QUERY(TRANSPOSE(QUERY(TRANSPOSE(
IF(IFERROR(REGEXEXTRACT(IFERROR(REGEXEXTRACT(C1:C, REPT("(.)", LEN(C1:C)))),
TEXTJOIN("|", 1, A1:A)))<>"", "♦"&IFERROR(REGEXEXTRACT(IFERROR(
REGEXEXTRACT(C1:C, REPT("(.)", LEN(C1:C)))), TEXTJOIN("|", 1, A1:A)))&"♣"&C1:C, ))
,,999^99)),,999^99), "♦")), "♣"))))
seriously, much better way, just add a custom function:
/**
* inner join on equality
*
* #param {Range} items1 Table 1
* #param {Range} items2 Table 2
* #param {Integer} ix1 0-based index of key in Table1
* #param {Integer} ix2 0-based index of key in Table2
*
* #customfunction
* #author marc meyer (marqueymarc)
*/
function innerJoinEQ(items1 = [[]], items2 = [[]], ix1= 0, ix2= 0) {
var res = [];
var item2ix = 0;
var map = new Map();
items1 = Array.isArray(items1)? items1: [[items1]];
items2 = Array.isArray(items2)? items2: [[items2]];
items2.forEach((item2) => {
let entries = map.get(item2[ix2]) || [];
entries.push(item2);
map.set(item2[ix2], entries);
});
items1.forEach((item1) => {
let entries = map.get(item1[ix1]) || [];
entries.forEach((rightPart) => {
let cp = rightPart.slice();
cp.splice(ix2, 1);
res.push([...item1, ...cp]);
})
});
return res;
}
I am wondering if something that i would like to achieve is possible, please look at the picture and read description below:
I would like to add a column to the right, where if a cell table[ActionType] = "TERMINATING", it calculates a difference between timestamps (timestamp for TERMINATING - timestamp for STARTING in below row). If the result is positive (>0) then store it in a column in a corresponding row (eg next to timestapm for terminating), if result is negative don't store it. And all of that applied to whole table.
I tried conditional column and i guess it cannot be done with this or at least I couldn't make it.
Will be very thankful for responses and tips!
Pre-requisite :- Add an Index Column using the query editor. Make sure they are in the next row to each other.
It is advisable to keep TimeStamp column as a DateTime Column itself.
So, if you can change your TimeStamp column to a DateTime column then try this :-
Difference =
Var Get_Action_Type = Table1[ActionType]
Var required_Index_1 = Table1[Index] + 1
Var required_Index = IF(required_Index_1 > MAX(Table1[Index]),required_Index_1-1, required_Index_1)
Var Current_Action_TimeStamp = Table1[TimeStamp]
Var next_Action_TimeStamp = CALCULATE(MAX(Table1[TimeStamp]),FILTER(Table1, Table1[Index] = required_Index))
Var pre_result = IF(Get_Action_Type = "TERMINATING", DATEDIFF(Current_Action_TimeStamp, next_Action_TimeStamp,SECOND), BLANK())
Var result = IF(pre_result > 0, pre_result, BLANK())
return result
And if you cannot change it to a Date Time, then try this calculated column,
Difference_2 =
Var Get_Action_Type = Table1[ActionType]
Var required_Index_1 = Table1[Index] + 1
Var required_Index = IF(required_Index_1 > MAX(Table1[Index]),required_Index_1-1, required_Index_1)
Var Current_Action_TimeStamp = Table1[Time_Stamp_Number]
Var next_Action_TimeStamp = CALCULATE(MAX(Table1[Time_Stamp_Number]),FILTER(Table1, Table1[Index] = required_Index))
Var pre_result = IF(Get_Action_Type = "TERMINATING", next_Action_TimeStamp - Current_Action_TimeStamp, BLANK())
Var result = IF(pre_result > 0, pre_result, BLANK())
return result
The Output looks as below :-
Kindly accept the answer if it helps and do let me know, how it works for you.
I'm trying to query a database using something like this:
let db = drop.database?.driver as? MySQLDriver
let query = "select \(fields) from \(table) where \(condition)"
let result = try db.raw(query)
I get the following Node object as result:
array([Node.Node.object(["field_name": Node.Node.string("value_info")])])
How can I get the value_info into a String variable?
You can use PathIndexable to step into the result object, then Polymorphic to cast it as a string.
Should look something like this:
let valueInfo = result[0, "field_name"]?.string
How can I add a dynamic key to an anonymous List such as the mydatetime below:
DateTime myDateTime = DateTime.Parse(datepickerval, ukCulture.DateTimeFormat);
var qid = (from p in db.Vw_INTERACTPEOPLE
select p
);
var AvilList = new List<object>();
var ddate = myDateTime.DayOfWeek.ToString().Substring(0, 3) + "Jul" + myDateTime.Day;
foreach (var q in qid)
{
AvilList.Add(
new
{// Availability
Name = q.Fullname,
here >>> ddate = "Some Test"
});
As adam says above there is no way to do this using Lists, however since the Slickgrid is expecting a Json return, I simply built the string in .net then returned it via the JavaScriptSerializer serializer, then in the code behind simply used eval to de-serialize back into an array.
