I am trying to generate a report in SSRS.
I have 2 tables as below:
Address table:
AddressId | AddressLine
AddressCountEachMonth
ID | AddressId | Date | Count
For each date(Year-Month) there is an entry in AddressCountEachMonth table with the count value.
What I would like to do is to be able to query AddressCountEachMonth to output the result as below
For example If I provide a start date: 2014-01-01 and and date: 2014-05-01
Query result should be:
Address | 2016-01 | 2016-02 | 2016-03 | 2016-04 | 2016-05|
x 5 1 0 2 4
y 2 3 4 0 2
...
...
is there any function in SQL Server that would help? I looked into STUFF but could not generate the result.
Luckily SSRS provides the ability to pivot dynamically so you will not have to hard code a query or build dynamic sql. Check out this article that shows step by step how to do this.

I have a need to manage a dataset for multiple customers - each customer manages a small table to update procedure volumes for the next five years. The table is structured like so:
+-------------+--------+--------+--------+--------+--------+
| | Year 1 | Year 2 | Year 3 | Year 4 | Year 5 |
+-------------+--------+--------+--------+--------+--------+
| Procedure A | 5 | 10 | 14 | 12 | 21 |
+-------------+--------+--------+--------+--------+--------+
| Procedure B | 23 | 23 | 2 | 3 | 4 |
+-------------+--------+--------+--------+--------+--------+
| Procedure C | 5 | 6 | 7 | 8 | 12 |
+-------------+--------+--------+--------+--------+--------+
The values in this table will be managed by each customer via MS PowerApps.
This same structure exists for every single customer. What is the best way to put all of these in one dataset?
Should I just add a column for CUSTOMER ID and just put all the data in there?
The process:
Utilizing PowerApps, a new customer deal will be generated and a row will be added for them in the SQL DB in a customer records table.
Simultaneously, the blank template of the above table should be generated for them.
Now, the customer can interface with this SQL table within PowerApps and add their respective procedure volumes.
The question isn't explained well but:
I would assume all of the customer specific data has at least one column that is the same. For instance CustomerName. You could create your own table with CustomerId, CustomerName, (any other fields you would like to see). If there isn't a concept of CustomerId on the customer's tables, you would have to join them on CustomerName. You could populate your own CustomerId for the new table.
I would be happy to help more if you could clarify the question and show a few examples.
The PostgreSQL database we have is common multi tenant database.
Question is, need to auto generate a unique number in "customerNumber" column which needs to be in sequential order.
The trick here is, the sequence needs to be unique for each "hotelLocation".
For "hotelLocation"= 1, If we have numbers: 1,2,3 for
"customerNumber"
For "hotelLocation"= 2, We need have numbers: 1,2,3
for "customerNumber"
Following is the sample layout for table,
#Entity
public class CustomerInfo {
#Id
#GeneratedValue(...)
private Long idNumber;
String hotelLocation;
/** Looking for option where, this number needs to
auto generated on SAVE, and need to be in separate sequence
for each hotelLocation **/
private Long customerNumber;
}
So finally here's how output will look like,
+----------+---------------+----------------+
| idNumber | hotelLocation | customerNumber |
+----------+---------------+----------------+
| 1 | 1 | 1 |
| 2 | 1 | 2 |
| 3 | 2 | 1 |
| 4 | 1 | 3 |
| 5 | 2 | 2 |
+----------+---------------+----------------+
I am ok with generating unique number both via Hibernate based or via Triggers also.
Searching across, i got following,
Hibernate JPA Sequence (non-Id)
But this one would keep generating in sequence without having separate sequence for each "hotelLocation"
Any solution to this will be very helpful. I am sure there are lot of people with multi tenant database looking for similar solution.
Thanks
You can do this easly with postgresql window function row_number().
Don't know your database but it should be something like this:
SELECT idNumber, hotelLocation,
row_number() OVER (PARTITION BY hotelLocation ORDER BY idNumber) AS
customerNumber FROM table

Yesterday, I was asked the same question by two different people. Their tables have a field that groups records together, like a year or location. Within those groups, they want to have a unique ID that starts at 1 and increments up sequentially. Obviously, you could search for MAX(ID), but if these applications have a lot of traffic, they'd need to lock the entire table to ensure the same ID wasn't returned multiple times. I thought about using sequences but that would mean dynamically creating a sequence for each group.
Example 1:
Records created during the year should increment by one and then restart at 1 at the beginning of the next year.
| Year | ID |
|------|----|
| 2016 | 1 |
| 2016 | 2 |
| 2017 | 1 |
| 2017 | 2 |
| 2017 | 3 |
Example 2:
A company has many locations and they want to generate a unique ID for each customer, combining a the location ID with a incrementing ID.
| Site | ID |
|------|----|
| XYZ | 1 |
| ABC | 1 |
| XYZ | 2 |
| XYZ | 3 |
| DEF | 1 |
| ABC | 2 |
One trick that is often under-used is to create a clustered index on Site / ID or Year / ID - BUT Change the order of the ID column to Desc rather than ASC.
This way when you need to scan the CI to get the Next ID value it only needs to check 1 row in the clustered index. I've used this on Multi-Billion Record tables and it runs quite quickly. You can get even better performance by partitioning the table by Site or Year then you'll get the added benefit of partition elimination when you run your MAX(ID) queries.
I have a scenario where I the dimension has a series of date / time members but instead I want to show it grouped to the day, how do I do that?
Example cube query:
select {[Measures].[Count]} on columns,
[Date].[Date].[Date] on rows
from [Cube]
and this query returns:
| count
2014-03-03 15:50:24.000 | 1
2014-03-03 16:05:10.000 | 1
2014-03-03 16:05:21.000 | 1
2014-03-02 16:30:13.000 | 1
I want to be able to show
| count
2014-03-03 | 3
2014-03-02 | 1
I'm using Microsoft Analysis Services 2008 R2 and the MDX queries for that
Maybe this is a little similar to what you're trying to achieve:
WITH
MEMBER [Measures].[countDays] AS
Count((EXISTING [Date].[Calendar].[Date]))
SELECT
{[Measures].[countDays]} ON COLUMNS
,[Date].[Calendar].[Month] ON ROWS
FROM [Adventure Works];
It returns the following:
I just want to map dynamically lookup column in LOOKUP Transform SSIS
In my task that look up column will all ways change
For Example:
TableA
```````
Col1 | Col2 | Col3
--------+-----------+---------
1 | 2 | 3
2 | 1 | 4
3 | 2 | 1
This time lookup columns are Col1+Col2
Next day it will change to Col2+Col3
I want to map dynamic input column with ssn
Depending on how the lookup columns are defined from one day to the next, it may be easier to make the query in the Lookup transformation dynamic instead. Check out the following link:
