I am designing an Electrical design software that will model an electrical utility system from the incoming Power Utility right down to the individual circuits such as computers and coffee machines.
I want to give each component of the system a dedicated table. eg. Transformers, Loads, cables, PowerPanels (called buses in this example).
Each component can be connected to one or many other components. I am using a parent/child table to manage the connections and plan to use a CTE to derive the hierarchical tree structure for a given component.
The voltage supplying any component in the system will be derived by finding the first instance of a transformer or a utility in the tree.
I have developed a query that can handle this as demonstrated below.
However, this only works for selecting one component in the CTE. I am looking for a way to select all buses and their connected voltage (nearest trafo or Utility). The only solution I can come up with is to use a table function on the above query. Is there a better way of doing this.

I'm using Postgres and I'm trying to create a trigger for insert or update new values into a table.
Here are the trigger and the function:
create or replace function trigf1() returns trigger as $$
begin
if (ballotbox.totvoters>votes.nofvotes) then
raise notice 'more voters than allowed';
return old;
else return new;
end if;
end;
$$ language plpgsql;
create trigger T1
Before insert or update on votes
for each row
execute procedure trigf1();
When I'm trying to update the tables "votes" and "ballotBox" I'm getting the error:
ERROR: missing FROM-clause entry for table "ballotbox"
LINE 1: SELECT (ballotbox.totvoters > votes.nofvotes)

I don't know if it's needed but here are the create tables and the insert values:

I'm using SQL Server Management to create a database (fot a work in the university), I'm trying to insert new values into a table but recieving error.
The two relevant tables I created are:
create table ballotBox
(
bno integer,
cid numeric(4,0) references city,
street varchar(20),
hno integer,
totvoters integer,
primary key (bno)
);
create table votes
(
cid numeric(4,0) references city,
bno integer references ballotBox,
pid numeric(3,0) references party,
nofvotes integer
);
I've entered first the values to ballotBox (as well as for the table 'city' and 'party'):
insert into ballotBox values
(1, 1, 'street1', 10, 1500),
(2, 1, 'street2', 15, 490),
(3, 1, 'street2', 15, 610),

please remove this line from votes statement then insert

following error code is seen on microsoft sql server-
Msg 215, Level 16, State 1, Line 1
Parameters supplied for object 'Countries' which is not a function. If the parameters are intended as a table hint, a WITH keyword is required.
Please help by sharing the reason ?
Don't use single quotes for column name.
INSERT INTO Countries ([sno], [Name])...
You can use brackets normally.
Or you can use double quote " if SET QUOTED_IDENTIFIER is ON (it should be by default)
Currently you have string literals which is causing SQL Server to interpret the code way different to what you expect
You could leave all the bracketed section out all together: SQL Fiddle
INSERT INTO Countries VALUES
This is therefore none explicit and not best practice (see comment by #AaronBertrand) - but still an alternative.
In generic terms I have a sequence of events, from which i'd like to select unique non-repeatable sequences using MS SQL Server 2008 R2.
Specifically in this case, each test has a series of recordings, each of which have a specific sequence of stimuli. I'd like to select the unique sequences of stimuli from inside the recordings of one test, insert them into another table and assign the sequence group id to the original table.
DECLARE #Sequence TABLE
([ID] INT
,[TestID] INT
,[StimulusID] INT
,[RecordingID] INT
,[PositionInRecording] INT
,[SequenceGroupID] INT
)
INSERT #Sequence
VALUES
(1, 1, 101, 1000, 1, NULL),
(2, 1, 102, 1000, 2, NULL),
(3, 1, 103, 1000, 3, NULL),
(4, 1, 103, 1001, 1, NULL),
(5, 1, 103, 1001, 2, NULL),
(6, 1, 101, 1001, 3, NULL),
(7, 1, 102, 1002, 1, NULL),
(8, 1, 103, 1002, 2, NULL),
(9, 1, 101, 1002, 3, NULL),
(10, 1, 102, 1003, 1, NULL),
(11, 1, 103, 1003, 2, NULL),
(12, 1, 101, 1003, 3, NULL),
(13, 2, 106, 1004, 1, NULL),
(14, 2, 107, 1004, 2, NULL),
(15, 2, 107, 1005, 1, NULL),
(16, 2, 106, 1005, 2, NULL)
After correctly identifying the unique sequences, the results should look like this
DECLARE #SequenceGroup TABLE
([ID] INT
,[TestID] INT
,[SequenceGroupName] NVARCHAR(50)
)
INSERT #SequenceGroup VALUES
(1, 1, '101-102-103'),
(2, 1, '103-103-101'),
(3, 1, '102-103-101'),
(4, 2, '106-107'),
(5, 2, '107-106')
DECLARE #OutcomeSequence TABLE
([ID] INT
,[TestID] INT
,[StimulusID] INT
,[RecordingID] INT
,[PositionInRecording] INT
,[SequenceGroupID] INT
)
INSERT #OutcomeSequence
VALUES
(1, 1, 101, 1000, 1, 1),
(2, 1, 102, 1000, 2, 1),
(3, 1, 103, 1000, 3, 1),
(4, 1, 103, 1001, 1, 2),
(5, 1, 103, 1001, 2, 2),
(6, 1, 101, 1001, 3, 2),
(7, 1, 102, 1002, 1, 3),
(8, 1, 103, 1002, 2, 3),
(9, 1, 101, 1002, 3, 3),
(10, 1, 102, 1003, 1, 3),
(11, 1, 103, 1003, 2, 3),
(12, 1, 101, 1003, 3, 3),
(13, 2, 106, 1004, 1, 4),

This is fairly easy to do in MySQL and other databases that support some version of GROUP_CONCAT functionality. It's apparently a good deal harder in SQL Server. Here's a stackoverflow question that discusses one technique. Here's another with some information about SQL Server 2008 specific solutions that might also get you started.
This will do it. Had to add an column to #SequenceGroup.
DECLARE #Sequence TABLE
([ID] INT
,[TestID] INT
,[StimulusID] INT
,[RecordingID] INT
,[PositionInRecording] INT
,[SequenceGroupID] INT
)
INSERT #Sequence
VALUES
(1, 1, 101, 1000, 1, NULL),
(2, 1, 102, 1000, 2, NULL),
(3, 1, 103, 1000, 3, NULL),
(4, 1, 103, 1001, 1, NULL),
(5, 1, 103, 1001, 2, NULL),
(6, 1, 101, 1001, 3, NULL),
(7, 1, 102, 1002, 1, NULL),
(8, 1, 103, 1002, 2, NULL),

(16, 2, 106, 1005, 2, NULL)
DECLARE #SequenceGroup TABLE

insert into #SequenceGroup

from #Sequence t2
group by RecordingID, TestID
order by RecordingID
select * from #SequenceGroup
update #Sequence
set SequenceGroupID = sg.ID

join #SequenceGroup sg on s.RecordingID=sg.RecordingID and s.TestID=sg.testid
