Typically no one with any choice would use Access as a front end, you are going to have to upset your users, unless that is you want to write the UI to match the look and feel of Access. I can think of worse fates for a developer but not many.

Per the other suggest that MS Access attempts to load all of it....
If that is the case then create a view(s) that limits the data set greatly. And link to that.

Hello,
And thanks in advance for the help.
I am using this query to group exams and count:
SELECT BPG.[GroupName], COUNT(A.[ProcedureID]) AS [Count]
FROM
[DB].[dbo].[Accessions] A
INNER JOIN [DB].[dbo].[table1] BP ON A.[ProcedureID] = BP.[ProcedureID]
INNER JOIN [DB].[dbo].[table2] BPG ON BP.[ProcedureGroup] = BPG.[ProcedureGroupID]
INNER JOIN [DB].[dbo].[table3] O ON A.[OrderID] = O.[OrderID]
INNER JOIN [DB].[dbo].[table4] F ON O.[OrderingFacilityID] = F.[FacilityID]
WHERE
--XRAY,US,PICC,EKG
(BPG.[GroupName] IN ('XRAY','EKG','US','PICC'))
AND
(F.[Name] LIKE '%' + @Facility + '%')
AND
(A.[ExamDate] >= CONVERT(DATETIME, @StartDate + @Year) AND A.[ExamDate] < CONVERT(DATETIME, @EndDate + @Year)
AND
(A.[Status] != 'Cancelled' AND A.[Status] != 'ADMIN CANCEL' AND A.[Status] != 'Cancelled - Dry Run'))
GROUP BY BPG.[GroupName]
Let's say the query only returns 'XRAY' and 'EKG' with a count. How can I also return that 'US' and 'PICC' have zero count. 
Thanks for the help.

Try to change join condition and see if you get result which you need.

Thank you. I am not sure what to change and that is why I asked for help.

I think this should be LEFT OUTER JOIN instead. Also you should change the count to be
count(nvl(a.ProcedureID,0)) so the NULL values will be counted as zero.

I tried your suggestion and that did not change anything. I am using MS SQL 2008 and the NVL function does not appear to be avaible so I tried the ISNULL function. I believe it does the same thing.
Thanks again.

Connect to the BPG table and all of its inner joins first.
Then do a LEFT OUTER JOIN to your Accessions (A) table and it's joins.
This will give you all of the group names and the 0's if there is nothing for that group.
SELECT BPG.[GroupName], COUNT(A.[ProcedureID]) AS [Count]
FROM
[DB].[dbo].[table2] BPG
LEFT OUTER JOIN
([DB].[dbo].[Accessions] A
INNER JOIN [DB].[dbo].[table1] BP ON A.[ProcedureID] = BP.[ProcedureID]
INNER JOIN [DB].[dbo].[table3] O ON A.[OrderID] = O.[OrderID]
INNER JOIN [DB].[dbo].[table4] F ON O.[OrderingFacilityID] = F.[FacilityID]
)
ON BP.[ProcedureGroup] = BPG.[ProcedureGroupID]
WHERE
.....
GROUP BY BPG.[GroupName]

Hi
I need to write trigger for more than one table i.e single trigger for multiple tables,user can not update,delete,insert on tables.If user try to modify on sql server table need to show alert.
I tried with after trigger for single table , it works fine .please suggest me better way.
regards,
Vishnu.

As far as I know you can't but this thread has come up with a possible solution that you could use assuming the code in the trigger is the same for all tables
Single Trigger on multiple tables[^]
Basically the solution they are suggesting is to have the triggers call a common stored proc

Database permissions were designed specifically for what you are looking for. If you are implementing access controls using triggers, I would say that is not a good idea.

There is table contain
ID Qty
----------
1 2
2 4
3 1
4 5
Now if i had to choose rows where sum of Qty equals to 10, How can i do this ?
like 2+4+1 = 7 but if i add 5 then 12
so ignore 2, then 4+1+5 = 10
How can i achieve this ?
I want id's of that rows which contain combination/sum equal to 10 (number i put)
|
|
|
|
|
declare @qty as decimal(18,2)<br />
set @qty=(select qty from mytable where id=4)<br />
<br />
select sum(qty)-@qty<br />
from myTable
By this example you will have result: 2+4+1=7

I think this cannot be done in a single query. You need to create combination by looping

To help you more how large would the table be that you have to loop through?

at any given time max rows can b only 50-100,i am getting these rows from Select statement.
I put them in temp table, iterate over them in loop, something like that ??
Then from these rows i have to get rows whose sums equals to Qty given (input).

I do not think that it is possible to write a single query to achieve what you are trying to do. There could be more than a single set of rows whose sum of qty = 10, how would you handle that?

So you want to solve a knapsack problem[^] in SQL? You do realize the problem is NP complete?

the link you had given pointed me to Backpack
I think what you mean is Knapsack_problem
I realize the complexity.
But at any given time max rows can b only 50-100,i am getting these rows from Select statement.
Then from these rows i have to get rows whose sums equals to Qty given (input).
So, will you please help me finding an algorithm to solve.
Regards

The problem is actually known as the subset sum problem as konduc pointed out, with a useful link.
As your number of rows is limited, you should load them all in memory and go for a normal solution, not a database-centric SQL one. Now start studying the keywords and links given to you, and help yourself with Google and/or some books. No one is going to do your job for you.

Hi all,
How can i convert MSSQL database to MySQL database ?
Thanks in advance.
|
|
|
|
|
I would start by going to Google and typing "convert mssql to mysql". That gives over 2 million hits. At least one of them must be useful.
|
|
|
|
|
The simplest way is to use the 'Generate Scripts' option in MSSQL and create the full script for the database and all its objects (including the data in the tables), then adapt the resulting script to MySQL syntax and run it on the MySQL database.
