Hi
Here is my code.
CREATE Trigger [trg_MovementsLog]
ON [dbo].[GtrDetail]
FOR INSERT
AS
INSERT INTO tblMovementsLog(GtrReference,Line,StockCode, QtyMoved, MovedBy,TransactionDate)
SELECT inserted.GtrReference,inserted.Line, inserted.StockCode, inserted.GtrQuantity AS QtyMoved,
SUBSTRING(LotTransactions.Narration,9,Len(LotTransactions.Narration)-8) AS MovedBy, inserted.TransactionDate
FROM inserted INNER JOIN
GtrLot ON inserted.GtrReference = GtrLot.GtrReference AND inserted.Line = GtrLot.Line INNER JOIN
LotTransactions ON GtrLot.Lot = LotTransactions.LotJob AND inserted.GtrReference = LotTransactions.Reference AND
inserted.StockCode = LotTransactions.StockCode
WHERE (inserted.TargetWarehouse = 'HS') AND (NOT (inserted.TransferComplete = 'Y')) AND (LotTransactions.Narration LIKE 'JOB_TRF_%')
I know however that my code does work. The trigger use to work fine until they re-installed the server. Also it runs if I manually insert a record into the GtrDetail table. It just does not run when it's basically inserted via a script (Well, so it seems).
Thanx for your assistance.

Hy!
I have problem enetring data from my application to the database datable. Basicly this is the table in MS Access 2003 desgin:
table name: details
table fields:
acountNum (Text, primary key)
itemId (Integer, primary key)
price(Decimal, format: 0,000)
quantity(Long integer)
The problem is when i use my insert method which has a line that goes like this:
komanda.CommandText = "INSERT INTO details(acountNum, itemId, price, quantity) VALUES ('" + par1 + "', " + par2 + ", " + par3 + ", " + par4 + ")";
I use step by stet debuging in studio and check that all the values are correct. But what happens is a problem on a third field of the table. It is formated to represent data in 0,000. That means if you enetr just 3 it wil show like 3,000 in the database. Or if you enetr 2,98 it will show as 2,980 etc..
So let us say that in above comand i pased in these values for variables that store values:
par1 = "98bg", par2 = 12, par3 = 4.7 and part4 = 10. When you execute this command in step by step debuger and check the CommandText property it will look like this:
komanda.CommandText = "INSERT INTO details(acountNum, itemId, price, quantity) VALUES ('98bg', 12, 4,700, 10)";
We see that the command (which has its connection field already set to a opened connection prior to this) immediatly applied the format rule of price field and turned 4.7 into 4,700. Now of course when i execute the DataAdapter.Update method it will thorow an exception because now we have only 4 fields to insert values and actually 5 values ('98bg', 12, 4,700, 10). 4.7 became 4,700. Of course if i remove the format for the price field in my databse the command works perfectly. But in this situation i ned to have this format of numbers for the price.
Does anyone have an idea how to over come this small problem?
Cheers!

I think parameters are working with ms access, this would remove all you troubles related to filling inside decimal values, dates, etc... mostly on computers that have different culture set. Parameters protect you also from sql injection.
Or you could use culture info to get decimal seperator and do a replace on string.
And i would write variable names on english, it has many benefits.
More on parameters here[^].
Edit: You can also write decimal number inside this way ...12, '4,700', 10...
But as i wrote, how do you know what is decimal seperator? Different culture, dufferent decimal seperator. Just use parameters.

hi,
i use VB.NET to develop an application which uses local MDB files as databases,
my question is:
is there anyway that i can indicate if a certain mdb file is already opened by another user ( even in access client ).
the goal is if for example a user open 2 instances of my application and connect with both instances to the same mdb file, i would like to display a warning messege on the 2nd connection that there is already 1 connection opened to this particular mdb file.
thanks in advance!

What I have done in the past, under a similar Access MDB requirement, is try to open the database exclusively, while trapping for the error if another user already has it opened, and then display the warning message if the error occurs. If the 'already opened' error did not occur, I would simply close the connection and then re-open the MDB shared.
|

Well you can improvise. Every time you check if some text file exists in the same directory as your databse. If it does not exists you create it. If it does exists that means that someone already opened the connection and you can implement code that generates warning.
Just don't forget to delete this file when you close connection.
As for the access client, every time you open mdb file with access or any other database managing software (this includes your connection that you create from your application) another file will be created in the same folder as your database. It will have the same name but different extension (.ldb). So you can combine this feature also with the one i described to get more detailed informatiopn.
I will try to code one example here(let us say your database name is "base.mdb"):
connection.Open();
if(File.Exists("C:\\opened.txt") == true && File.Exists("base.ldb") == true)
MessageBox.Show("Connection is opened by your application");
if(File.Exists("base.ldb") == true)
MessageBox.Show("Connection is opened by Access client");
Else
File.CreateText("C:\\opened.txt")
Of course dont forget to delete the text file after closing connection:
connection.Close();
if(File.Exists("C:\\opened.txt") == true)
File.Delete("C:\\opened.txt")
Any way this is the general idea. In a text file you could write much additional information on who opened the databse, when, etc..
Cheers!

i need the messege to be displayed even if the file is already opened by MS ACCESS.

First, this is a race condition waiting to happen.
Second, applications don't always end cleanly. Sooner or later something will go wrong and you will end up with the "opened.txt" file existing even though no one has the database open, or the .ldb file can hang around if Access does not close cleanly.
|
|
|
|
|
You don't need to create a text file. Access creates a .ldb file to hold locking information when the .mdb is opened. Just look for that. 
There are some circumstances when Access does not create the .ldb file e.g. the directory that the .mdb is in is set to read only. But then Access will only allow one user to open the database so the second attempt will generate an error or exception.

Try this(Assuming that the original table name is tblSENTBYSENTON)
ALTER PROCEDURE dbo.GETRECORDS
-- Add the parameters for the stored procedure here
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
-- VARIABLE DECLARATION
DECLARE @SENTBY INT
DECLARE @SENTON DATETIME
DECLARE @ACCEPTBY INT
DECLARE @ACCEPTON DATETIME
DECLARE @NEWTBLSENTBYSENTON TABLE
(
SENTBY INT,
SENTON DATETIME
)
-- STEP 1: DECLARE A CURSOR
DECLARE MYCURSOR CURSOR FOR
SELECT SENTBY,SENTON,ACCEPTBY,ACCEPTON
FROM TBLSENTBYSENTON
-- STEP 2: OPEN THE CURSOR
OPEN MYCURSOR
FETCH MYCURSOR INTO @SENTBY,@SENTON,@ACCEPTBY,@ACCEPTON
-- STEP 3: START THE LOGIC
WHILE @@Fetch_Status = 0
BEGIN
-- STEP 4: INSERT RECORDS INTO TABLE @NEWTBLSENTBYSENTON
-- BASED ON THE LOGIC PROVIDED
IF(@SENTBY = @ACCEPTBY)
BEGIN
INSERT INTO @NEWTBLSENTBYSENTON(SENTBY,SENTON)
VALUES(@SENTBY,@SENTON)
END
ELSE
BEGIN
INSERT INTO @NEWTBLSENTBYSENTON(SENTBY,SENTON)
VALUES(@SENTBY,@SENTON)
INSERT INTO @NEWTBLSENTBYSENTON(SENTBY,SENTON)
VALUES(@ACCEPTBY,@ACCEPTON)
END
-- STEP 5: GET THE NEXT RECORD
FETCH MYCURSOR INTO @SENTBY,@SENTON,@ACCEPTBY,@ACCEPTON
END
--STEP 6: CLOSE THE CURSOR
CLOSE MYCURSOR
--STEP 7: DEALLOCATE THE CURSOR
DEALLOCATE MYCURSOR
SELECT * FROM @NEWTBLSENTBYSENTON
END
With the same input, I got the same output:
Sentby SentOn
1 2009-06-15 19:40:36.000
32 2009-06-29 13:36:59.450
1 2009-06-30 12:25:45.303
1 2009-06-15 19:40:36.000
1 2009-06-16 13:19:34.693
1 2009-06-15 19:40:36.000
2 2009-06-15 19:40:36.000
1 2009-06-16 19:40:36.000
Hope this helps.

Thanks for reply....
but i need a same result in select query without using Cursor,temptable,looping etc.,
because superior says it is a time consuming process.

Try this
SELECT Sentby,SentOn
FROM tblSentBySentOn
UNION
SELECT AcceptBy,AcceptOn
FROM tblSentBySentOn
WHERE Sentby <> AcceptBy
For grouping the results use this
SELECT A.Sentby, A.SentOn
FROM(
SELECT Sentby,SentOn
FROM tblSentBySentOn
UNION
SELECT AcceptBy,AcceptOn
FROM tblSentBySentOn
WHERE Sentby <> AcceptBy
) A ORDER BY A.SentOn
Hope this helps

I'm developing a quiz application and i want to access the questions randomly from my dadtabase. Is it possible? please help.
ML Lingwati

|
|
|

Create the primary key to your questions as an integer (ID), then have the random number generator select the corresponding ID.
|
|
|
|

Hi,
The random numbers can be generated in multiple ways.
But in all the cases the questions should have a unique QuestionId( a Primary Key)
Step 1:
Create a table (say tblQuestions) with QuestionId(int Primary Key), Questions(Varchar(50))
Step 2:
Insert some values:
QuestionId Questions
---------------------
1 Q1
2 Q2
3 Q3
4 Q4
5 Q5
6 Q6
7 Q7
8 Q8
9 Q9
10 Q10
11 Q11
12 Q12
13 Q20
14 Q25
15 Q30
Solution 1:
Suppose you have a fixed set of questions (say 1 to 30).
Fire this query
SELECT QUESTIONS
FROM TBLQUESTIONS
WHERE QUESTIONID = ROUND(((30 - 1) * RAND() + 1), 0)
where 30 is the upper limit and 1 is lower limit
Solution 2:
Suppose your question may grow to any length dynamically
Fire this query
SELECT QUESTIONS
FROM TBLQUESTIONS
WHERE QUESTIONID = CAST(RAND() * N AS INT)
Where N is any number.
Means if you have records(i.e. Questions) from 1 to 10, N = 10
if you have records(i.e. Questions) from 1 to 50, N = 50
if you have records(i.e. Questions) from 1 to 100, N = 100 etc.
Solution 3:
For the same above scenario, the following query can also be use
SELECT QUESTIONS
FROM TBLQUESTIONS
WHERE QUESTIONID = ABS(CAST(NEWID() AS binary(6)) %N) + 1
Where N is any number.
Solution 4:
Send the random numbers from your front end application to the backend either in INLINE SQL or in STORED PROC, and retieve the questions based on the QuestionId.
Hope this helps
