Hello,

New to SQL. Basic syntax knowledge. Trying to do two updates to single field in table below:

AIRCRAFTID OPERATOR REG FULLTYPE MSN AIR DATE
1126_00009 Aircraft Trust & Financing Corp N200AX IAI 1126 Gulfstream G200 9 NAS 2011-07-04

1126_00026 Franklin P Johnson Jr N800PJ IAI 1126 Gulfstream G200 26 YVR 2002-03-02

Update 1 is to set Make = 0, where MIN(date) of AIRCRAFTID (first instance of AIRCRAFTID

SELECT *, MIN(date)
FROM AIRLOG2012
GROUP BY AIRCRAFTID,
ORDER BY AIRCRAFTID, DATE, REG;

This query worked, but I am trying to work out the 2nd update query

Update 2 is to set Make = 1, where MIN(date) of AIRCRAFTID (next instance(s) of AIRCRAFTID where REG is different.

I hope that I have got this correct?

Thanks,

Stephen

I would like to have

Are you sure you are using sql server? That query should give you an error - and it's not an update.

try
select *, make = -1 + row_number() over (partition by AIRCRAFTID order by date)
from tbl



==========================================
Cursors are useful if you don't know sql.
SSIS can be used in a similar way.

I am using SQLite, and it looks to have worked.

I am really new to this. I guess my previous update query set all MAKE rows to 0. So lets start again. I am working with sqlite.

Here is some sample data:

AIRCRAFTID REG FULLTYPE DATE

Here is the syntax I used to search for the 1st date instance for each AIRCRAFTID group:

SELECT *, MIN(date)
FROM AIRLOG2012
GROUP BY AIRCRAFTID
ORDER BY AIRCRAFTID, DATE, REG;

This returns correct info and number of rows. So, I would like to update MAKE to 0 based on this search syntax.

Then I would like to do a 2nd update to MAKE = 1 based on this search syntax.

SELECT *, MIN(date)
FROM AIRLOG2012
GROUP BY AIRCRAFTID, REG
ORDER BY AIRCRAFTID, DATE, REG;

Where any subsequent REG changes for a unique AIRCRAFTID would set MAKE = 1.

I would like it to look like the following:

AIRCRAFTID REG FULLTYPE DATE MAKE
A320000713 HB-IPU Airbus A319-112 2002-06-04 0
A320000714 N714AW Airbus A320-214 1998-11-22 0

Hey sodeep. Thanks for the help. My goal is the 1) identify the when I first saw the AIRCRAFTID 2) Identify any changes in REG for that same AIRCRAFTID. See below.

I first saw the aircraft (A320000716) as N716AW on 1998-11-28. Then it was re-registered as G-BXKB, and I saw it a few more times as G-BXKB; then it was re-registered again as G-OMYA. So, I would like to mark the 1st time I saw A320000716 (0), and then hopefully identify subsequent registration changes such as G-BXKB (1), G-OMYA (1). Any sightings/records where the REG does not change can remain null.

A320000716 N716AW Airbus A320-214 1998-11-28 0
A320000716 G-BXKB Airbus A320-214 2000-09-10 1
A320000716 G-BXKB Airbus A320-214 2002-06-01
A320000716 G-BXKB Airbus A320-214 2002-06-08
A320000716 G-OMYA Airbus A320-214 2007-10-29 1

For AIRCRAFTID A320000721, I have seen it multiple times, but as the same REG. So, only the 1st instance needs to have MAKE = 0.

A320000721 C-FZUL Airbus A319-114 1997-11-23 0
A320000721 C-FZUL Airbus A319-114 2001-04-21
A320000721 C-FZUL Airbus A319-114 2002-05-11
A320000721 C-FZUL Airbus A319-114 2002-05-25
A320000721 C-FZUL Airbus A319-114 2002-06-15
A320000721 C-FZUL Airbus A319-114 2005-02-11
A320000721 C-FZUL Airbus A319-114 2005-04-02

I have 68,000 records, so I hope I can accomplish this without too much coding.

Thanks again,

Stephen

sodeep. Thank you. I have a few more AIRCRAFTID's to update prior to updating the table. So, one last dumb question: Do I need enter all of the data for the 67,000 rows into the query as formatted above to update all the rows?

Thanks again,

Stephen

No You just have to change @T with your original table.

You just need this:

;WITH CTE as 
(
SELECT
*,
ROW_NUMBER() OVER(PARTITION BY AIRCRAFTID ORDER BY Date)Seq,
ROW_NUMBER() OVER(PARTITION BY AIRCRAFTID,REG ORDER BY Date)Seq1
FROM AIRLOG2012
)


Update t
Set t.MAKE = Case When Seq = 1 then 0 Else 1 End
from AIRLOG2012 t
inner join CTE c on c.<Primary Key>= t.<Primary Key>
Where Seq = 1 OR (Seq1 = 1 and Seq <> Seq1)

You don't need to declare @t, SODEEP just did that since you didn't provide any DDL or usable sample data. If you already have a table AIRLOG2012, just replace @T in SODEEP's query with AIRLOG2012
and you should be good to go


;WITH CTE as
(
SELECT
*,
ROW_NUMBER() OVER(PARTITION BY AIRCRAFTID ORDER BY Date)Seq,
ROW_NUMBER() OVER(PARTITION BY AIRCRAFTID,REG ORDER BY Date)Seq1
FROM AIRLOG2012
)


Update T
Set t.MAKE = Case When Seq = 1 then 0 Else 1 End
from AIRLOG2012 t
inner join CTE c on c.TPK = t.TPK
Where Seq = 1 OR (Seq1 = 1 and Seq <> Seq1)

Select * from AIRLOG2012
Order by TPK

So, It looks like I might have to try another option, as sqlite does not support CTE queries I just discovered. Bummer.

Thanks

Stephen,

Hello Sodeep,

Thanks for the assistance. It is working with the temp table setup and a couple of queries. Next, I am hoping that I might be able to use the Begin Transaction syntax to stack the multiple queries.

Thanks again,

Stephen
