I have a Microsoft Reporting Services report (local report, VS2005) and am trying to produce a rather tricky report...
I have two tables returned from a SQL query. The first is a master table that has a list of set ID's corresponding to sets of records in the second, and has a record set like so:
+----------------------+
| SetID |
+----------------------+
| 1 |
| 2 |
| 3 |
| ... |
| |
The second table is a list of bjorks, let's call them. It looks like this:
+----------+-------+-----------+-----------
| BjorkID | SetID | BjorkName | ...
+----------+-------+-----------+-----------
| 1 | 1 | Bob |
| 2 | 1 | Jones |
| 3 | 1 | Smith |
| 4 | 2 | Jack |
| 5 | 2 | Daniels |
| 6 | 3 | Moo |
| 7 | 3 | Bean |
| 8 | 3 | Bond |
| 9 | 3 | Jim |
| ... | ... | ... |
| | | |
Now, I need to generate a report that prints off one page for each Set, and each Set's page contains a list of its Bjorks.
Can anyone point me in the right direction to mangle RDLC into doing this? :)
Cheers!
You can accomplish your task with just the second table/data set and parent and detail groups on a table or list.
Parent groups on SetID. Detail groups on BjorkID. Set your page breaks accordingly.

I have multiple MYSQLI tables for multiple details and options about a touristic package.
I have package containing the main information, then I have package_option which contains unknown number of options added to the package, and there's package_images which contains the images.
I want to get all the information in one query, but it's prooving a difficult task. Let me explain.
I've used JOIN with but the problem was if the package_option had 3 options and the package_images had 6 images, the result was a 6*4 plus 1 (package) result table.
I would like a result containing all the fields, as many as they originaly are in the tables, not multiplied for each match in every table.
For example, the table I aim for looks like that:
-------------------------------------------------------------------------
| ID | name | description | price | option | image | size | explanation |
-------------------------------------------------------------------------
| 1 | test | some desc | 50 $ | opt. 1 | img1 | 30 | |
| | | | | opt. 2 | img2 | | |
| | | | | opt. 3 | img3 | | |
| | | | | | img4 | | |
| | | | | | img5 | | |
| | | | | | img6 | | |
Right now, the above table gets populated in every field, but it's multiplied, so I don't get only 6 rows, but 24.
I did a lot of JOINS, I'm not a beginer, which is even more frustrating, but it's the first time I try to do that, a select from multiple tables with different columns and unknown number of rows.
package_option and package_images looks like that:
-------------------------------------
| ID | package_id | option / image |
-------------------------------------
| 1 | 1 | opt. 1 / img 1 |
| 2 | 2 | opt. 2 / img 2 |
..... etc
so I don't know how many rows I'll have.
Thank you in advance for t
I have the next table setup, two tables related by an intermediate table, like this:
Client
| client_id | ...|field_X |
| 1 | ...|value1 |
| 2 | ...|value2 |
| 3 | ...|value3 |
Project
| project_id | ...|field_X |
| 1 | ...| |
| 2 | ...| |
| 3 | ...| |
| 4 | ...| |
| 5 | ...| |
| 6 | ...| |
| 7 | ...| |
client_project
| client_id | project_id|
| 1 | 2 |
| 1 | 3 |
| 2 | 4 |
| 2 | 5 |
| 3 | 6 |
| 3 | 7 |
The field_x in the table project is new and i have to fill it with the data from table client to get approximately something like this:
Project
| project_id | ...|field_X |
| 1 | ...| |
| 2 | ...|value1 |
| 3 | ...|value1 |
| 4 | ...|value2 |
| 5 | ...|value2 |
| 6 | ...|value3 |
| 7 | ...|value3 |
i dont know hot to deal with the intermediate table. i have tried this code but it doesnt work.
INSERT INTO project
(field_x)
(select field_x
from
client_project
inner join
client
where client_project.client_id = client.client_id
);
I have the idea of what i have to do but i am not able to translate it into a sql command because of the intermeditate table.Could someone explain how to deal with it?
Thanks in advance.
I assume you already have all entries in the project table but they're missing the Field_X property? So what you need is an update, not an insert
UPDATE project p, client c, project_client pc SET p.Field_X=c.Field_X WHERE p.ID=pc.ProjectID AND c.ID=pc.ClientID
However, be advised that having the same data in two places is not a good practise; if possible always put one fact in only one place.
I have a database which contain a list of items (item)
+----+-----------------------+-------+--------+-------+
| id | name | width | height | depth |
+----+-----------------------+-------+--------+-------+
| 1 | Some_toy | 35 | 28 | 30 |
| 2 | Pepperoni_pizza | 17 | 30 | 35 |
| 3 | Wood_table | 45 | 42 | 57 |
| 4 | Guitar | 26 | 45 | 75 |
| 5 | Awesome_TV | 80 | 35 | 10 |
+----+-----------------------+-------+--------+-------+
On my website, users can select items inside this list to create their own list of item. User's list are stored in the following table user_list_items
+----+--------------+---------+--------+
| id | id_user_list | id_item | number |
+----+--------------+---------+--------+
| 1 | 6 | 3 | 2 |
| 2 | 6 | 5 | 1 |
| 3 | 6 | 7 | 5 |
| 4 | 7 | 7 | 3 |
| 5 | 9 | 3 | 1 |
+----+--------------+---------+--------+
But, because my list cannot contain every item in the world, I want to allow users to add a custom item.
My problem is that I don't want to store users custom items inside my table item because this table contains the item displayed by default.
However, If I don't save custom items inside my table item, I still must save them somewhere else. So I've created another table custom_item which is an exact replica of item.
With this solution, I've added a foreign key id_custom_item in my table user_list_items which give the following
+----+--------------+---------+----------------+--------+
| id | id_user_list | id_item | id_custom_item | number |
+----+--------------+---------+----------------+--------+
| 1 | 6 | 3 | 0 | 2 |
| 2 | 6 | 0 | 25 | 1 |
| 3 | 6 | 7 | 0 | 5 |
| 4 | 7 | 7 | 0 | 3 |
| 5 | 9 | 3 | 0 | 1 |
+----+--------------+---------+----------------+--------+
And now I have a problem with user_list_items because can link to item or to custom_item and it seems like a very bad practice.
My question is, how could I save user's custom input with a list of predetermined item ?
Sorry this question is not very well formulated but I couldn't find any other way to express it.
If the objection to storing custom items in item table is just that the contents are displayed by default, I'd add a column set to 'Y' or 'N' to the table and add that column to the WHERE clause of the query that populates the default list, eg AND default_flag = 'Y'
I am trying to get average of latency for each items that holds into two separate mysql table. Let me more clarify that I have two mysql tables as below,
table: monitor_servers
+-----------+-----------------+
| server_id | label |
+-----------+-----------------+
| 1 | a.com |
| 2 | b.com |
+-----------+-----------------+
table: monitor_servers_uptime
+-------------------+-----------+-----------+
| servers_uptime_id | server_id | latency |
+-------------------+-----------+-----------+
| 1 | 1 | 0.4132809 |
| 3 | 1 | 0.4157769 |
| 6 | 1 | 0.4194210 |
| 9 | 1 | 0.4140880 |
| 12 | 2 | 0.4779439 |
| 15 | 2 | 0.4751789 |
| 18 | 2 | 0.4762829 |
| 22 | 2 | 0.4706681 |
+-------------------+-----------+-----------+
Basically, each domains associated with the same id_number in both tables. While I am running the query below, getting average of each items.
select monitor_servers.label, avg(monitor_servers_uptime.latency)
from monitor_servers,monitor_servers_uptime
where monitor_servers.server_id = monitor_servers_uptime.server_id
group by monitor_servers.server_id;
The query ended up,
+---------------------+-------------------------------------+
| label | avg(monitor_servers_uptime.latency) |
+---------------------+-------------------------------------+
| a.com | 0.41393792995 |
| b.com | 0.47551423171 |
+---------------------+-------------------------------------+
My questions are doing am i in wright way while getting average of the each items and how can i insert new average result of each items into a new column on table monitor_servers ? And also what happens if some of latency rows are NULL ?
**Edit : What i am trying to achieve in one query result is **
+-----------+----------+------------------+
| server_id | label | avg. |
+-----------+----------+------------------+
| 1 | a.com | 0.41393792995 |
| 2 | b.com | 0.47551423171 |
+-----------+-----------------------------+
Thanks in advance,
Your calculation seems to be correct.
You could add another column to the monitor_servers using sql:
ALTER TABLE monitor_servers ADD avg_latency DEFAULT 0.0 NOT NULL
For doing the AVG calculation check this answer.

Regardless of the database you are using, the concept of what you are trying to achieve is called "Pivot Table".
Here's an example for mysql:
http://en.wikibooks.org/wiki/MySQL/Pivot_table
Some databases have builtin features for that, see the links below.
SQLServer:
http://msdn.microsoft.com/de-de/library/ms177410.aspx
Oracle:
http://www.dba-oracle.com/t_pivot_examples.htm
You can always create a pivot by hand. Just select all the aggregations in a result set and then select from that result set.
