Using JOINS in MySQL - sql

I have this query which works perfectly:
SELECT *
FROM Customer
WHERE SacCode IN
(
SELECT SacCode
FROM SacCode
WHERE ResellerCorporateID = 392
ORDER BY SacCode
)
AND CustomerID IN
(
SELECT CxID
FROM CustAppointments
WHERE AppRoomID IN
(
SELECT AppRoomID
FROM ClinicRooms
WHERE ClinID IN
(
SELECT ClinID
FROM AppClinics
WHERE ClinDate >='20090101'
AND ClinDate <='20091119'
)
)
)
However, I need to see the value of ClinDate (inside the last nested query) so I've been told I need to rework the query using JOINS.
I have no idea how, can someone help please?
Thanks.


Here's a start:
SELECT *
FROM Customer c
INNER JOIN CustAppointments ca ON ca.CxId = c.CustomerID
INNER JOIN ClinicRooms cr ON cr.AppRoomID = ca.AppRoomID
INNER JOIN AppClinics ac ON ac.ClinID = cr.ClinID
WHERE ap.ClinDate BETWEEN '20090101' AND '20091119'
AND SacCode IN (SELECT sc.SacCode
FROM SacCode sc
WHERE sc.ResellerCorporateID = 392)
This will allow you to select columns from AppClinics.

SQL Server aggregate function without group by

I want to include tcon.Inductive_Injection_Hours, tcon.Capacitive_Injection_Hours without applying group by. How can I do that?
SELECT
bp.Serial_Number,
tcon.Serial_Number AS ConverterSerialNumber,
MAX(tcon.Time_Stamp) AS DateStamp,
tcon.Inductive_Injection_Hours,
tcon.Capacitive_Injection_Hours
FROM
dbo.Bypass AS bp
INNER JOIN
dbo.Converter AS c ON bp.Bypass_ID = c.Bypass_ID
INNER JOIN
dbo.Converter_Tel_Data AS tcon ON c.Converter_ID = tcon.Converter_ID
WHERE
(bp.Site_ID = 7)
GROUP BY
bp.Serial_Number, tcon.Serial_Number,
tcon.Inductive_Injection_Hours, tcon.Capacitive_Injection_Hours
ORDER BY
ConverterSerialNumber

I have figured it out.
select [data].Serial_Number,Time_Stamp,Inductive_Injection_Hours,Capacitive_Injection_Hours,b.Serial_Number from Converter_Tel_Data as [data]
inner join dbo.Converter AS c On [data].Converter_ID = c.Converter_ID
inner join dbo.Bypass as b on c.Bypass_ID = b.Bypass_ID
WHERE
(Time_Stamp = (SELECT MAX(Time_Stamp) FROM Converter_Tel_Data WHERE Converter_ID = [data].Converter_ID)) And ([data].Site_ID=7)
ORDER BY [data].Serial_Number

You can use row_number - either in a CTE/derived table or using a trick with TOP 1.
Select Top 1 With Ties
bp.Serial_Number
, tcon.Serial_Number AS ConverterSerialNumber
, tcon.Time_Stamp AS DateStamp
, tcon.Inductive_Injection_Hours
, tcon.Capacitive_Injection_Hours
From dbo.Bypass AS bp
Inner Join dbo.Converter AS c On bp.Bypass_ID = c.Bypass_ID
Inner Join dbo.Converter_Tel_Data AS tcon ON c.Converter_ID = tcon.Converter_ID
Where bp.Site_ID = 7
Order By
row_number() over(Partition By bp.Serial_Number Order By tcon.Time_Stamp desc)
This should return the latest row from the tconn table for each bp.Serial_Number.

How to use Order By and With clause

I am using following SQL query to fetch set of records.

Query is working fine only thing is the records are not sorted.
I want to use order by on PROJECT_INSTANCE_PIPELINE_ID so that all the rows are sorted. When I use ORDER BY clause seeing following error.
Error:
The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified.
Not sure how to use Order By and With Clause together.
Any thoughts!

try like below i just used PROJECT_NAME in order by

Aggregate function results in select statement

Hopefully the code below should demonstrate what I'm trying to achieve.
The issue is that none of the input selects are resolved by the time I try to calculate VatableCash so I get "Invalid Column" when trying to select it.
Sorry if there's something plainly obvious I can do here. SQL isn't one of my strong suits.
select
OrderHeader.ID,
sum(OrderLine.NetPrice) as OrderLineNetPrice,
sum(OrderLine.GrossPrice) as OrderLineGrossPrice,
sum(
case when PaymentOption_ID = 8
then Payment.Amount
else 0
end
) as TotalCashAmount,
((OrderLineGrossPrice - OrderLineNetPrice) / OrderLineGrossPrice) * TotalCashAmount as VatableCash
from OrderHeader
inner join Payment on Payment.OrderHeader_ID = OrderHeader.ID
inner join OrderLine on OrderLine.OrderHeader_ID = OrderHeader.ID
group by OrderHeader.ID

You need to use sub query.
you can try this.
;WITH CTE AS
(
select
OrderHeader.ID,
sum(OrderLine.NetPrice) as OrderLineNetPrice,
sum(OrderLine.GrossPrice) as OrderLineGrossPrice,
sum(
case when PaymentOption_ID = 8
then Payment.Amount
else 0
end
) as TotalCashAmount
from OrderHeader
inner join Payment on Payment.OrderHeader_ID = OrderHeader.ID
inner join OrderLine on OrderLine.OrderHeader_ID = OrderHeader.ID
group by OrderHeader.ID
)
SELECT *,
((OrderLineGrossPrice - OrderLineNetPrice) / OrderLineGrossPrice) * TotalCashAmount as VatableCash
FROM CTE

Love the cross apply! Use it whenever you want some handy extra columns.
select
OrderHeader.ID,
sum(OrderLine.NetPrice) as OrderLineNetPrice,
sum(OrderLine.GrossPrice) as OrderLineGrossPrice,
TotalCashAmount,
((OrderLineGrossPrice - OrderLineNetPrice) / OrderLineGrossPrice) * TotalCashAmount as VatableCash
from OrderHeader
inner join Payment on Payment.OrderHeader_ID = OrderHeader.ID
inner join OrderLine on OrderLine.OrderHeader_ID = OrderHeader.ID
cross apply ( select sum(
case when PaymentOption_ID = 8
then Payment.Amount
else 0
end
)) as subquery(TotalCashAmount)
group by OrderHeader.ID

Sqlite self join using alias

I have such sql query:
SELECT LeftCurrency.LeftCurrency, RightCurrency.RightCurrency FROM
(
SELECT DISTINCT [SecurityData].[Value] AS 'LeftCurrency'
FROM [SecurityData]
JOIN [Fields] ON [Fields].[Id] = [SecurityData].[FieldId]
WHERE [Fields].[Mnemonic] = 'CRNCY'
) AS LeftCurrency
JOIN
(
SELECT DISTINCT [SecurityData].[Value] AS 'RightCurrency'
FROM [SecurityData]
JOIN [Fields] ON [Fields].[Id] = [SecurityData].[FieldId]
WHERE [Fields].[Mnemonic] = 'CRNCY'
) AS RightCurrency
ON LeftCurrency.LeftCurrency != RightCurrency.RightCurrency
it works ok, but I have two similar sub-queries.
Also I tried something like this:
SELECT * FROM
(
SELECT DISTINCT [SecurityData].[Value] AS 'Currency'
FROM [SecurityData]
JOIN [Fields] ON [Fields].[Id] = [SecurityData].[FieldId]
WHERE [Fields].[Mnemonic] = 'CRNCY'
) AS leftCurrency, leftCurrency AS rightCurrency
WHERE leftCurrency.Currency != rightCurrency.Currency
But it doesn't work.
So is it possible to get rid of sub-query duplication?

In SQLite 3.8.3 or later, you could use a common table expression:
WITH Currency(Currency) AS (
SELECT DISTINCT [SecurityData].[Value]
FROM [SecurityData]
JOIN [Fields] ON [Fields].[Id] = [SecurityData].[FieldId]
WHERE [Fields].[Mnemonic] = 'CRNCY'
)
SELECT LeftCurrency.Currency AS LeftCurrency,
RightCurrency.Currency AS RightCurrency
FROM Currency AS LeftCurrency
JOIN Currency AS RightCurrency ON LeftCurrency.Currency != RightCurrency.Currency
Alternatively, use a temporary view.

how to get the latest price in sql query

I need get the price of lasted QuoteDate.
Right now i have query like these
SELECT dbo.INMT.Material, dbo.INMT.LastVendor, dbo.INMT.AvgCost, dbo.MSQD.Status, dbo.MSQH.QuoteDate, dbo.MSQD.UnitPrice
FROM dbo.INMT INNER JOIN
dbo.MSQD ON dbo.INMT.MatlGroup = dbo.MSQD.MatlGroup AND dbo.INMT.Material = dbo.MSQD.Material INNER JOIN
dbo.MSQH ON dbo.MSQD.MSCo = dbo.MSQH.MSCo AND dbo.MSQD.Quote = dbo.MSQH.Quote
GROUP BY dbo.INMT.Material, dbo.INMT.LastVendor, dbo.INMT.AvgCost, dbo.MSQD.Status, dbo.MSQD.UnitPrice, dbo.MSQH.QuoteDate
ORDER BY dbo.INMT.Material
and get the following result
and how can i run a query just get the highlighted record.i try to do something like where QuoteDate =max......but maybe my grouyping is not correct.
thanks

So, assuming SQL Server 2005+, you can use a CTE and ROW_NUMBER():
;WITH CTE AS
(
SELECT I.Material,
I.LastVendor,
I.AvgCost,
MD.Status,
MH.QuoteDate,
MD.UnitPrice,
RN = ROW_NUMBER() OVER( PARTITION BY I.Material, I.LastVendor,
I.AvgCost, MD.Status,
MD.UnitPrice
ORDER BY MH.QuoteDate DESC)
FROM dbo.INMT I
INNER JOIN dbo.MSQD MD
ON I.MatlGroup = MD.MatlGroup
AND I.Material = MD.Material
INNER JOIN dbo.MSQH MH
ON MD.MSCo = MH.MSCo
AND MD.Quote = MH.Quote
)
SELECT Material,
LastVendor,
AvgCost,
Status,
QuoteDate,
UnitPrice
FROM CTE
WHERE RN = 1

Use HAVING QuoteDate=max... after the order by clause.
