I have a stored procedure like this : http://tinyurl.com/pbk8qfb
CREATE PROCEDURE PS_TAB_TSEN(NOMFIC VARCHAR(70), LIBSEN VARCHAR(35),
CODAPPFOF VARCHAR(3))
DEFINE NUMINTNAV VARCHAR(10);
BEGIN;
LET NUMINTNAV = '0';
SELECT TO_CHAR(NUM_INT_NAV) INTO NUMINTNAV
FROM TAB_INAV WHERE NOM_FIC = NOMFIC;
MERGE INTO TAB_TSEN T
USING (SELECT COD_SEN, LIBSEN AS LIB_SEN, CODAPPFOF AS COD_APP_FOF
FROM TAB_TSEN
WHERE COD_SEN = NUMINTNAV) AS S
ON (T.COD_SEN = S.COD_SEN)
WHEN MATCHED THEN
UPDATE SET T.COD_SEN = S.COD_SEN, T.LIB_SEN = S.LIB_SEN,
T.COD_APP_FOF = S.COD_APP_FOF
WHEN NOT MATCHED THEN
INSERT (T.COD_SEN, T.LIB_SEN, T.COD_APP_FOF)
VALUES (S.COD_SEN, S.LIB_SEN, S.COD_APP_FOF);
COMMIT;
END PROCEDURE;
When I run it all is good, but when I check in the table I see no result, for the insert statement and for the update statement too.
I call it like this:
CALL PS_TAB_TSEN('~/PSS/Order/OrderList.aspx', 'Liste des commandes', 'NET');
I don't understand what is going on...
Problem solved, I replace my stored procedure by this one :
CREATE PROCEDURE PS_TAB_TSEN(NOMFIC VARCHAR(70), LIBSEN VARCHAR(35), CODAPPFOF VARCHAR(3))
DEFINE ISPRESENT INTEGER;
DEFINE NUMINTNAV VARCHAR(10);
BEGIN;
LET NUMINTNAV = '0';
SELECT TO_CHAR(NUM_INT_NAV) INTO NUMINTNAV FROM TAB_INAV WHERE NOM_FIC = NOMFIC;
LET ISPRESENT = 0;
SELECT COUNT(*) INTO ISPRESENT FROM TAB_TSEN WHERE COD_SEN = NUMINTNAV;
IF(ISPRESENT > 0) THEN
UPDATE TAB_TSEN SET T.COD_SEN = S.COD_SEN, T.LIB_SEN = S.LIB_SEN, T.COD_APP_FOF = S.COD_APP_FOF
ELSE
INSERT INTO TAB_TSEN (T.COD_SEN, T.LIB_SEN, T.COD_APP_FOF) VALUES (S.COD_SEN, S.LIB_SEN, S.COD_APP_FOF);
END IF;
COMMIT;
END PROCEDURE;

I have followed the previous code and try to call a stored procedure
ALTER PROCEDURE [dbo].[sp_test]
#in char(5) = ' ',
#out smallint = 0 output
AS
BEGIN
SET NOCOUNT ON;
SET #out = 100
END
Then in the VB6, i try to request this stored procedure by below
strConn = "Select * from TBL where 1=2"
Set rsCmd = objCCS.ExecuteStatement(strConn, adUseServer, adOpenDynamic, adLockBatchOptimistic)
Dim rdoqry_data2 As ADODB.Command
Set rdoqry_data2 = CreateObject("Adodb.command")
Set rdoqry_data2 = rsCmd.ActiveCommand
rdoqry_data2.CommandType = adCmdStoredProc
rdoqry_data2.CommandText = "sp_test"
rdoqry_data2(0).Direction = adParamReturnValue
rdoqry_data2(1).Direction = adParamInput
rdoqry_data2(2).Direction = adParamOutput
rdoqry_data2(2).Type = adSmallInt
rdoqry_data2(1) = "123"
rdoqry_data2.Execute
But it flow an exception ODBC driver does not support the requested properties.
Can anyone find the problem?
Thanks.
Where exactly does the exception appear? I guess the exception is the result of calling the procedure sp_test and not the result of executing objCCS.ExecuteStatement, right?
My approach to call the stored procedure sp_test from VB6 would be:
Dim rdoqry_data2 As ADODB.Command
Set rdoqry_data2 = New ADODB.Command
With rdoqry_data2
Set .ActiveConnection = (your connection object)
.Parameters.Append rdoqry_data2.CreateParameter("#in", adVarchar, adParamInput, 5, "123")
.Parameters.Append rdoqry_data2.CreateParameter("#out", adSmallInt, adParamOutput, 2)
.CommandType = adCmdStoredProc
.CommandText = "sp_test"
.Execute
End With
First you have to create the command object and assign the connection object to it. In this case you need two parameter objects. First parameter is an input parameter with a maximum size of 5 bytes (char(5)) and the content "123". Second parameter is an output parameter with a max. size of 2 bytes (smallint). Finally you have to tell the command object to call a stored procedure with the name "sp_test".
Does this work for you?
I'm trying to implement a kanban agile board like Trello in my application. I'm wondering how to do it the best way. I'm considering these entities:
Board
has many Lists
List
has many Cards
Card
contains some content
However I'm stuck with ordering of Cards. Each Card should have a sort position to sort Cards in particular order in a List. When dragging a Card, I should change it's position and save it in the database. What is the most efficient way of doing this?
Adding a position field to each Card seems redundant since I would have to recalculate positions of all Cards in a List (or two) after I drag a Card to a different position (there will be hundreds of Cards). I was thinking of storing an array of all Card ids in a List and sort Cards by this array. What are pros/cons of this solution? And are there any better solutions?
I'm using Ruby on Rails and PostgreSQL.
UPDATE
Using #cske answer I came up with the following solution:
CREATE OR REPLACE FUNCTION move_buyer_card(
new_list_id INT
, param_id INT
, new_position INT
) RETURNS FLOAT4
LANGUAGE plpgsql SECURITY DEFINER
AS $$
DECLARE
var_lower_bound FLOAT4;
var_upper_bound FLOAT4;
var_new_weight FLOAT4; /*between 0 and 1*/
BEGIN
IF new_position < 2 THEN /*first position*/
var_lower_bound := 0;
SELECT MIN(weight) FROM Buyers
WHERE board_list_id = new_list_id
INTO var_upper_bound;
IF var_upper_bound IS NULL THEN /*empty list*/
var_upper_bound := 1;
END IF;
ELSE /*not first position*/
WITH ordered_cards AS (
SELECT id, RANK() OVER (ORDER BY weight ASC) AS rank, weight
FROM Buyers WHERE board_list_id = new_list_id
)
SELECT cards0.weight, cards1.weight from ordered_cards cards0
JOIN ordered_cards cards1
ON cards0.rank = cards1.rank - 1
WHERE cards1.rank = new_position
INTO var_lower_bound, var_upper_bound;
IF NOT FOUND THEN /*only 1 item in list OR last position*/
SELECT MAX(weight) FROM Buyers WHERE board_list_id = new_list_id
INTO var_lower_bound;
IF var_lower_bound IS NULL THEN /*empty list*/
var_lower_bound := 0;
END IF;
var_upper_bound := 1;
END IF;
END IF;
var_new_weight := var_lower_bound + (var_upper_bound - var_lower_bound) / 2;
UPDATE Buyers
SET weight = var_new_weight,
board_list_id = new_list_id
WHERE id = param_id;
RETURN var_new_weight;
END;
$$;
Consider this, trick is not storing the position, but a weight so you can insert between any two elements
create table listOfCards (
listId INTEGER
,cardId INTEGER
,weigth FLOAT4
,PRIMARY KEY (listId,cardId)
);
CREATE OR REPLACE FUNCTION addCard(
plistId INT
, pcardId INT
, ppos INT
) RETURNS FLOAT4
LANGUAGE plpgsql SECURITY DEFINER
AS $$
DECLARE
vlb FLOAT4;
vub FLOAT4;
vnw FLOAT4;
BEGIN
IF 2 > ppos THEN
vlb := 0;
SELECT min(weigth) FROM listOfCards WHERE listId = plistId INTO vub;
IF vub IS NULL THEN /*empty list*/
vub := 2;
END IF;
ELSE
with corder as (select cardId,RANK() OVER (order by weigth asc) as r,weigth FROM listOfCards WHERE listId=1)
select c0.weigth,c1.weigth from corder c0 JOIN corder c1 ON c1.r = c0.r + 1 where c1.r = ppos INTO vlb,vub;
IF NOT FOUND THEN
SELECT max(weigth) FROM listOfCards WHERE listId = plistId INTO vlb;
IF vlb IS NULL THEN /*empty list*/
vlb := 0;
END IF;
vub := (vlb+1) * 2;
END IF;
END IF;
vnw := vlb + (vub-vlb) /2;
INSERT INTO listOfCards(listId, cardId, weigth)
VALUES (plistId,pcardId,vnw )
ON CONFLICT ON CONSTRAINT listofcards_pkey DO UPDATE SET weigth = vnw ;
RETURN vnw;
END;
$$;
Usage:
select addCard(1,1,1);
select addCard(1,2,1);
select addCard(1,3,2);
select addCard(1,4,2);
select addCard(1,5,5);
select addCard(1,5,2);
select * from listOfCards ORDER BY weigth;
Result:
1,2,0.5
1,5,0.5625
1,4,0.625
1,3,0.75
1,1,1
I am trying to develop a stored procedure within TERADATA to handle and manage exceptions.
The stored procedure should raise the error to the caller, which is an SSIS Package.
I am trying to illustrate this by creating a stored procedure for illustration only.
I have these tables:
Table_A:
- ID INT
- ITEM_NUM INT
- DESC VARCHAR(20)
- CREATE_DTTM VARCHAR(2O)
Table_B:
- ID INT
- ITEM_NUM INT
- DESC VARCHAR(20)
- CREATE_DTTM VARCHAR(2O)
I have two tables that will be inserting data from two SELECT statements.

SELECT 1, '222', 'SOME DESC',CURRENT_TIMESTAMP;
H98:Begin
set varSQLState = SQLSTATE;
set varErrorMessage= 'This message is displayed, ITEM_NUM invalid characters';
end H98;

ELSE
END TRANSACTION; -- COMMIT TRANSACTION
END IF;

The problem that I am facing with the above stored procedure is that error message that I get is not the one that I am expecting. Since error is intentionally created in my second statement I am expecting to get: This message is displayed, ITEM_NUM invalid characters but I am getting This message should not be displayed
Now if I modify the PROCEDURE to have multiple handlers, one for each statement, I do get the correct error message, but now since I am intentionally generating the error in the first statement it does not terminate the procedure, it handles the error and sets the proper message but continues to process the next statement which I am not expecting to do this, so how can I terminate this procedure?

So I have this query
$sql = "set #row_number := 0;
SELECT *
FROM (
SELECT user_id, #row_number := #row_number +1 pos
FROM user
ORDER BY plays DESC
) AS row_to_return
WHERE user_id = '{$_SESSION['user']->user_id}'";
echo $sql;
$user_pos = R::exec($sql);
Have tried to use exec, findAll, findRow - no result.
This thing did the trick:
$sql = "SELECT *
FROM (
SELECT user_id, #row_number := #row_number +1 pos
FROM user
ORDER BY plays DESC
) AS row_to_return
WHERE user_id = '{$_SESSION['user']->user_id}'";
$set_sql = 'set #row_number := 0';
R::exec($set_sql);
$user_pos = R::getRow($sql);
i want to get back ref cursor for the below sp. But it's not working.. not getting any records.. So please help me for this.
DATA_INPUTLIST - it's collection type for two variables (mtn, mtnEffDate)
DATA_RESULTLIST - It's also a collection type for 3 variables (id, effDate, mtn)

The first things that stands out to me is the following:
SELECT MTN, TO_DATE(MTN_EFF_DATE, 'mm/dd/yyyy') into v_mtn, v_mtn_eff_date
FROM TABLE (pSearchCriteria)
WHERE
ROWNUM = i;
For i greater than 1 this will not return anything. For the reason why, see this question. In fact, because you're using SELECT ... INTO ..., you'll get a no data found error if i is greater than or equal to 2.
You don't need an SQL query just to fetch some values out of PL/SQL collections. Try replacing this query with
v_mtn := pSearchCriteria(i).MTN;
v_mtn_eff_date := TO_DATE(pSearchCriteria(i).MTN_EFF_DATE, 'mm/dd/yyyy');
I don't have your tables nor the data in them so I can't be sure why you're getting no data. I can only hazard at some obvious suggestions: is vCount zero? If you put suitable values for v_mtn and v_mtn_eff_date and run your query on its own, separate from this stored procedure, does it return any rows?
