Hi all,
I need your help.
I'm creating a program to display the circuit of Bus by city and stop.
This is my example and i don't know how to do it:
I have 3 differents circuits of bus and each circuit can have one or multiple transfer to another circuit.
So let's say i'm looking for a trajet from City1/Stop1 (source) To City3/Stop11(destinat ion)
Here's the scenario:
Bus 1:
------
City1/ Stop1: 6h30 am (bus departure) / SOURCE
City1/ Stop2: 6h50 am -> Transfer to Bus 2 (transfert at 6h55am)
City1/ Stop3: 6h55 am
City1/ Stop4: 7h00 am
...
City1/ Stop12: 12h50 pm
City1/ Stop13: 13h00 pm
...
Bus 2:
------
City2/ Stop1: 6h00 am (bus departure)
City2/ Stop2: 6h10 am
City2/ Stop3: 6h20 am
City1/ Stop2 (e.g stop 4): 6h55 am ***
City2/ Stop5: 7h00 am
City2/ Stop6: 7h10 am
City2/ Stop7: 7h20 am -> Transfer to Bus 3 (at 7h28 am)
City2/ Stop8: 7h30 am
City2/ Stop9: 7h40 am -> Transfer to Bus 8
City2/ Stop10: 7h50 am
City2/ Stop11: 8h05 am
City2/ Stop12: 8h15 am
etc...
Bus 3:
------
City3/ Stop1: 5h00 am (departure)
City3/ Stop2: 5h40 am
City3/ Stop3: 6h20 am
City3/ Stop3: 6h50 am
City3/ Stop5: 7h00 am
City3/ Stop6: 7h20 am
City3/ Stop7: 7h28 am ***
City3/ Stop8: 7h35 am
City3/ Stop9: 7h40 am
City3/ Stop10: 7h45 am
City3/ Stop11: 7h55 am / DESTINATION
City3/ Stop12: 8h15 am
etc...
So my trajet should be:
-----------------------
Bus1:
Departure: City1/Stop1: 6h00 am
Arrival: City1/Stop2: 6h50 am
Transfert to Bus 2:
Departure: City1/ Stop2 (e.g stop 4): 6h55 am
Arrival: City2/ Stop7: 7h20 am
Transfert to Bus 3:
Departure: City3/ Stop7: 7h28 am
Arrival: City3/ Stop11: 7h55 am
Can anyone help me and tell me how to do it as a recursive stored procedure ?
I tried many examples/algorithms but i didn't succeed.
I have 2 differents tables.
The first table is dedicated for Circuits/Bus:
CREATE TABLE [dbo].[Trajets](
[TRAJET_ID] [int] IDENTITY(1,1) NOT NULL,
[CIRCUIT_ID] [int] NOT NULL,
[CITY_ID] [int] NOT NULL,
[STOP_ID] [int] NOT NULL,
[DAY_ID] [int] NOT NULL,
[HOUR] [int] NOT NULL,
[MINUTE] [int] NOT NULL,
[TYPE_ARRET] [nvarchar](50) NULL,
[TRANSFERT] [bit] NOT NULL,
[TYPE_TRANSFERT] [int] NULL,
[DIRECTION] [nvarchar](50) NULL,
CONSTRAINT [PK_Trajets] PRIMARY KEY (TRAJET_ID)
)
The 2nd one is dedicated for Transfers:
CREATE TABLE [dbo].[Transferts](
[TRANSFERT_ID] [int] IDENTITY(1,1) NOT NULL,
[TRAJET_ID] [int] NOT NULL,
[CIRCUIT_ID] [int] NOT NULL,
CONSTRAINT [PK_Transferts] PRIMARY KEY (Transfert_Id)
)
Thank you
Paul

Hi,
I work primarily on Oracle databases. I am trying to convert a

Does DB2 UDB v8.2 (Windows/AIX) supports recursive stored procedures ??
After some research, I found out that to call recursively in DB2, the
stored procedure should be CALLed using dynamic SQL. I am not sure
whether it is the right way. Am I missing something ?? Please let me
know...

I wrote an algorithm to get all the relatives of a person in a family tree. I'm basically getting all the users from the DB and am doing the recursive logic in code, so that there is only 1 call made to the DB. However, I am trying to do the same thing within a stored procedure in SQL using recursive CTEs (I think the performance might be better) but I'm finding it really tough to craft the CTE. I would really appreciate if someone could...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
