Filter the values from the source in merge query in mssql

it should still fix some issue You could wrap the values clause with a select statement, using top 1 with ties and order by row_number... - like this:
code :
MERGE tableA AS t
USING (
        SELECT TOP 1 WITH TIES *
        FROM
            (VALUES 
                ('datakeyA1', 'datetime value'), 
                ('datakeyB1', 'datetime value'),
                ('datakeyA1', 'max datetime value')
            ) AS s (Key1, datetime)
        ORDER BY ROW_NUMBER() OVER(PARTITION BY Key1 ORDER BY datetime DESC)
        ) s
        ON s.Key1 = t.Key1
WHEN MATCHED THEN 
    UPDATE 
    SET    Val = s.datetime
WHEN NOT MATCHED THEN 
    INSERT (Key1, datetime)
    VALUES (s.Key1, s.datetime);

I wish did fix the issue. Here's the version for Lucene 3.3

Filter source array based on the current filter and put its certain values to the ng-repeat item

I wish did fix the issue. You can use a filter for this.
The logic is simple:
code :
var app = angular.module('flight-schedule', []);

app.controller('SelectCtrl', function($scope) {
  $scope.flights = [
    {
      city: 'Ashgabat',
      destinations: ['Almaty', 'Amritsar']
    },
    {
      city: 'Amritsar',
      destinations: ['Ashgabat']
    },
    {
      city: 'Almaty',
      destinations: ['Ashgabat']
    }
  ];

  $scope.schedules = [{
    "city_from": "Ashgabat",
    "city_to": "Almaty",
    "aviacompany": "Türkmenhowaýollary DMG",

    "dep_time": "20-20",
    "land_time": "*00-10",
    "ret_flight_num": "T5-716"
  }, {
    "city_from": "Almaty",
    "city_to": "Ashgabat",

Filter values with a join MSSQL


By : Andrea
Date : March 29 2020, 07:55 AM
help you fix your problem Since nothing is wrong with the data or the code the only conclusion is that the row with A.[G_L Account No_] NOT IN was not executed.
You probably didn't mark it by mistake... :-)

MSSQL database query translate given values


By : 陈林平
Date : March 29 2020, 07:55 AM
wish of those help I have simple MSSQL query:
code :
SELECT CASE WHEN tw_todo = 'T' THEN 1 ELSE 0 END as td FROM tw__work

Why is it no slower to SELECT into a temp table then MERGE than it is just to MERGE from the source query?


By : user2037685
Date : March 29 2020, 07:55 AM
Hope that helps Provided that the amount of data put into the temp table isn't too large, the server should be able to keep it all in memory and not have to spill it out to disk. As such, B in your A -> B, B -> C is exceptionally cheap to access compared to C (and possibly A). You normally expect I/O costs to swamp most others in straightforward queries.
In the grand scheme of things, I'd still prefer the single MERGE if it's performing adequately enough. Don't try to help SQL Server out by breaking up the task into a series of subtasks - that's a job for the optimizer, and whilst it may not always pick an optimal plan, it will usually pick one that's good enough.
