How I can migrate clickhouse countIf function to linq2db?
Example:
from =>
SELECT customer_id,
countIf(customer_id, active_month between 0 and 1) as active_month1
FROM myt_table
GROUP BY customer_id
to =>
from x in my_table
group x by x.customerId into g
select new {
CustomerId = g.Key,
ActiveMonth1 = Sql.CountIf(x, p => p.customerId, p => p.ActiveMonth.between(1, 6))
}
I tried this option but it has problems
from x in MyTable
group x by x.CustomerId into g
select new {
CustomerId = g.Key,
FirstMonthCount = g.Count(p => 1 >= p.ActiveMonth && p.ActiveMonth <= 6)
}
Try the following workaround:
from x in MyTable
group x by x.CustomerId into g
select new
{
CustomerId = g.Key,
FirstMonthCount = g.Sum(p => 1 >= p.ActiveMonth && p.ActiveMonth <= 6 ? 1 : 0)
}

I have this sql query:
$sql = "SELECT d.doctor_name, a.patient_name, s.date, s.time FROM appointments AS a LEFT JOIN doctors AS d ON d.id = a.doctor_id LEFT JOIN slots AS s ON s.id = a.slot_id WHERE s.date > '2019-10-01' ORDER BY d.doctor_name DESC ";
$result = $mysqli->query($sql);
echo '<pre>';
while ( $row = $result->fetch_assoc() ) {
print_r($row);
}
echo '</pre>';
and it's output is:
Array
(
[doctor_name] => Khaled
[patient_name] => Nawaz
[date] => 2019-10-11
[time] => 02:01
)
Array
(
[doctor_name] => Khaled
[patient_name] => Anik
[date] => 2019-10-07
[time] => 02:31
)
Array
(
[doctor_name] => Khaled
[patient_name] => Manik
[date] => 2019-10-02
[time] => 03:31
)
Can I merge the date and time column as slot_date_time?
So output will be e.g:
Array
(
[doctor_name] => Khaled
[patient_name] => Manik
[slot_date_time] => 2019-10-02 03:31
)
Try this query
SELECT d.doctor_name, a.patient_name, CONCAT(s.date, ',', s.time) AS slot_date_time
FROM appointments AS a LEFT JOIN doctors AS d
ON d.id = a.doctor_id LEFT JOIN slots AS s
ON s.id = a.slot_id
WHERE s.date > '2019-10-01'
ORDER BY d.doctor_name DESC
Use CONCAT for merge two column as one column
I've got a SQL query that when I run it in SQL Server Mgmt Studio takes 15 seconds to complete. When I translate it to linq and run it in LINQPad it takes 1:50 to complete. Have I just completely bungled the "translation" to linq?
This is the SQL:
WITH details AS (
SELECT DISTINCT SerialNumber, OrgLevel3, OrgLevel4, [Status Label]
FROM vw_PSM_AssetIntransit
WHERE yyyyww = DATENAME(yy, GETDATE()) + RIGHT('00' + DATENAME(wk, GETDATE()), 2) AND pro_status <> 'retired'
)
SELECT OrgLevel3, OrgLevel4, COUNT(DISTINCT SerialNumber) Total,
SUM(CASE WHEN [Status Label] NOT IN ('15-21 Days InTransit', '8-14 Days InTransit', 'over 21 Days InTransit') THEN 1 ELSE 0 END) Compliant
FROM details
GROUP BY OrgLevel3, OrgLevel4
ORDER BY 1, 2
and this is the LINQ I translated it to:
var now = DateTime.Now;
var dtf = System.Globalization.DateTimeFormatInfo.CurrentInfo;
var calendar = dtf.Calendar;
var yearWW = now.Year * 100 + calendar.GetWeekOfYear(now, dtf.CalendarWeekRule, dtf.FirstDayOfWeek);
var badStatusLabels = new string[] { "15-21 Days InTransit", "8-14 Days InTransit", "over 21 Days InTransit" };
var details = (
from r in Vw_PSM_AssetIntransit
where r.yyyyww == yearWW && r.Pro_status != "retired"
select new { r.SerialNumber, r.OrgLevel3, r.OrgLevel4, r.StatusLabel }
).Distinct();
var data = from r in details
group r by new { r.OrgLevel3, r.OrgLevel4 } into grp
orderby grp.Key.OrgLevel3, grp.Key.OrgLevel4
select new
{
OrgLevel3 = grp.Key.OrgLevel3,
OrgLevel4 = grp.Key.OrgLevel4,
Total = grp.Select(x => x.SerialNumber).Distinct().Count(),
Compliant = grp.Sum(x => !badStatusLabels.Contains(x.StatusLabel) ? 1 : 0)
};
Console.WriteLine(data);
This is what LINQPad shows the SQL query came out as:

This is my mysql query
SELECT a.model_name,
IF( b.officially_released_year = '".$currentyear."',1,0 ) AS release_year,
IF( b.officially_released_month = '".$first_month."' OR b.officially_released_month = '".$second_month."' OR b.officially_released_month = '".$third_month."' OR b.officially_released_month = '".$currentmonth."' ,1,0) AS release_month

WHERE a.model_id = b.model_id AND a.model_status = '1'
ORDER BY a.model_created_on DESC
I want to do one more filtering option in this query. I need to get the records based on release_year = 1 & release_year = 1. I have done release_year and release_month columns through IF STATEMENT in MYSQL QUERY
release_year
IF( b.officially_released_year = '".$currentyear."',1,0 ) AS release_year
release_month
IF( b.officially_released_month = '".$first_month."' OR b.officially_released_month = '".$second_month."' OR b.officially_released_month = '".$third_month."' OR b.officially_released_month = '".$currentmonth."' ,1,0) AS release_month
How do I get the records based on these values (release_month = 1 & release_year = 1) in this query? I have tried WHERE release_month = 1 AND release_year = 1 but this one returns unknown column
You could do this:
SELECT
*
FROM
(
SELECT
a.model_name,
a.model_created_on,
IF( b.officially_released_year = '".$currentyear."',1,0 ) AS release_year,
IF( b.officially_released_month = '".$first_month."' OR b.officially_released_month = '".$second_month."' OR b.officially_released_month = '".$third_month."' OR b.officially_released_month = '".$currentmonth."' ,1,0) AS release_month
FROM ".TBL_CAR_ADD_MODELS." a, ".TBL_CAR_SPEC_GENERAL." b
WHERE a.model_id = b.model_id AND a.model_status = '1'
) AS tbl
WHERE tbl.release_year=1 AND release_month=1
ORDER BY tbl.model_created_on DESC

ORDER BY OEEL.custno, OEEL.shipto, OEEL.prodcat
The function has + (which in MySQL is not a concatenation symbol) between the variables.
Try:-
CONCAT_WS('-', OEEL.orderno, OEEL.ordersuf, OEEL.prodcat) AS `Unique`
CONCAT_WS does a concatenation With Separator .the first parameter is the separator with the others concatenated together.
I am trying to combine these 2 queries in such a way to determine who the PI is that owns equipment (>$100K value). I have the ability to find all the equipment one PI owns that is greater then 100k. I also have the ability to see all the PIs. I just cannot get these 2 queries to combine. I have tried with a WHERE subquery and an EXIST subquery. I want to be able to find all the equipment (matched with its PI owner) where the PI exists in query #2.
Query #1 for finding equipment of a specific PI

Perhaps you're looking for the IN keyword in your WHERE clause?
