How To Count No Of Items In Nested Table

Aug 28, 2007

I have the following table
Region Table
ID
ParentID
RegionName

RestaurantTable
ID
RestaurantName
RegionID

What i tried to do is count the number of restaurants by specific regionname. My current query is
Select RegionID, RegionName, count(*) as RestaurantNo
From Region Inner Join Restaurant
On Region.ID = Restaurant.RegionID

However I only get the results below
RegionID RegionName RestaurantNO
1 A1 0
2 A1.1 2
3 A1.2 1
4 A1.3 0

Where A1.1 , A1.2, and A1.3 are children of A1 in Region table
The result is not correct due to A1 should have 3 in RestaurantNo due to it contains A1.1 , A1.2 and A1.3
Could anyone help me to solve this problem.
Thank you

Table Update With Count In Nested Query

Oct 8, 2012

I have added some SQL to an Access form which updates the dbo_BM_Map table when the user hits the Apply button. There is a temp table with various fields, two being "Chapter_No" and "Initial_Mapping_Complete" which the update is based on.

I want this update to only apply to chapters that only have one name in the "Initial_Mapping_Complete" column. If a chapter has more than one then the update should ignore it. The attached screengrab shows you. The update should ignore chapter 19 as there are two people (Jim and James) in the Initial_Mapping_Complete field. Here is my code.

pdate dbo_BM_Map inner Join Temp_Progression_Populate
on dbo_BM_Map.Product_ID = Temp_Progression_Populate.Product_ID
Set dbo_BM_Map.Initial_Mapping_Complete = Temp_Progression_Populate.Initial_Mapping_Complete
Where dbo_BM_Map.Chapter_No = Temp_Progression_Populate.Chapter_No
And Temp_Progression_Populate.Initial_Mapping_Complete in
(Select count(Initial_Mapping_Complete), Chapter_No
from Temp_Progression_Populate
Group by Chapter_No
Having Count(Initial_Mapping_Complete) = 1)

Nested SELECT Query That Also Returns COUNT From Related Table

Mar 4, 2005

OK heres the situation, I have a Categories table and a Products table, each Category can have one or many Products, but a product can only belong to one Category hence one-to-many relationship.

Now I want to do a SELECT query that outputs all of the Categories onto an ASP page, but also displays how many Products are in each category eg.

CatID | Name | Description | No. Products

0001 | Cars | Blah blah blah | 5

etc etc

At the moment I'm doing nesting in my application logic so that for each category that is displayed, another query is run that returns the number of products for that particular category. It works ok!

However, is there a way to write a SQL Statement that returns all the Categories AND number products from just the one SELECT statement, rather than with the method I'm using outlined above? The reason I'm asking is that I want to be able to order by the number of products for each category and my method doesn't allow me to do this.

Many thanks!

SQL Server 2012 :: Identify Sets That Have Same Items (where Set ID And Items In Same Table)

Feb 25, 2015

I am struggling to come up with a set-based solution for this problem (i.e. that doesn't involve loops/cursors) ..A table contains items (identified by an ItemCode) and the set they belong to (identified by a SetId). Here is some sample data:

SetIdItemCode
1A
1B
24
28
26
310
312
410

[code]....

You can see that there are some sets that have the same members:

- 1 and 10
- 2 and 11
- 7, 8 & 9

What I want to do is identify the sets that have the same members, by giving them the same ID in another column called UniqueSetId.

Count Items In Recordset

Feb 18, 2008

Hi All,
I have a question regarding recorcounts. I have a set of records that i got after writing the sql query. The record layout is something like:

ID Amountdue
1 5
2 10
3 40
4 0
5 -6
6 230
7 -5
8 100
9 -1
10 0

I want to get the count of each amount due more than 0, less than 0 and equal to 0 all in the same query. So the result should look something like

Order PassGT0 PassLT0 PassEQ0
1 5 NULL NULL
2 NULL 3 NULL
3 NULL NULL 2

i can do 3 separate select count(*) if these were stored in a table but the result set was created using joins in the Query Analyser. I can also achieve the above result using unions with 3 separate queries with different conditions but this way i have to join the tables 3 times in each query and this is slowing down the query.

Please let me know if there is some other way i can achieve this.

Thanks

Can Anyone Help Me With A Nested Count??

Jul 24, 2007

Hi All,

I am trying to do a nested count and cannot seem to get it to work. I do realize I cannot do this within the expression so I have been trying to use the code block (report > report properties > code tab) to do this and I have zero experience with VB.

This is for a PO delivery report. The first expression is just counting how many lines on an individual PO are late divided by total number of lines on the PO. In second expression I would like to count how many POs that have a late line on it.

Here is what I have so far.

Expression 1 with count function (this work properly):
=iif(Fields!DS_Desired_Recv_Date.Value is nothing,
((Count(IIF(Fields!LAST_RECEIVED_DATE.Value > Fields!DESIRED_RECV_DATE.Value,1,Nothing))/Count(Fields!LINE_NO.Value))),
((Count(IIF(Fields!ACTUAL_RECV_DATE.Value > Fields!DS_Desired_Recv_Date.Value,1,Nothing))/Count(Fields!LINE_NO.Value))))

Code block:
Private Shared count as Integer
count=0
Public Function IncrementCount() As String
count = count +1
IncrementCount = CStr(count)
End Function

Expression 2
=iif(Fields!DS_Desired_Recv_Date.Value is nothing,
((Count(IIF(Fields!LAST_RECEIVED_DATE.Value > Fields!DESIRED_RECV_DATE.Value,1,Nothing))/Count(Fields!LINE_NO.Value))),
((Count(IIF(Fields!ACTUAL_RECV_DATE.Value > Fields!DS_Desired_Recv_Date.Value,1,Nothing))/Count(Fields!LINE_NO.Value))))

& IIf(iif(Fields!DS_Desired_Recv_Date.Value is nothing,
((Count(IIF(Fields!LAST_RECEIVED_DATE.Value > Fields!DESIRED_RECV_DATE.Value,1,Nothing))/Count(Fields!LINE_NO.Value))),
((Count(IIF(Fields!ACTUAL_RECV_DATE.Value > Fields!DS_Desired_Recv_Date.Value,1,Nothing))/Count(Fields!LINE_NO.Value)))) > 0, Code.IncrementCount(), Nothing)

The error:
[rsCompilerErrorInCode] There is an error on line 2 of custom code: [BC30188] Declaration expected.
Build complete -- 1 errors, 0 warnings.

Also "Code.IncrementCount()" is underlined with red zigzag indicating an error.

How do I get the code block to work with expression 2?

Thanks,

Blair

T-SQL (SS2K8) :: How To Group Total Count Of Similar Items

Mar 30, 2015

We sell & ship packages that contain multiple items within them. The actual package (we call it the "parent item") is in the same table as the items within it ("child items"). If the record is a child item within a package, its "ParentId" field will contain the ItemId of the package.

So some sample records of a complete package would look like this:

ItemId | ParentId | Name | QtyAvailable
----------------------------------------
1 | NULL | Package A | 10
2 | 1 | Item 1 | 2
3 | 1 | Item 2 | 3

ItemId's 2 & 3 are items contained within the ItemId 1 package.

Now however, the client wants us to build a report showing all packages (all items where ParentId is NULL) however, they want to see the QtyAvailable of not only the package but the items as well (a total of 15 when using the example above), all grouped into a single line. So a sample report line would look like this:

Name | Available Qty
--------------------------
Package A | 15
Package B | 100

How can I do a SELECT statement that SUMS the "QtyAvailable" of both the parent & child items and displays them along with the package name?

Nested SQl With Count, Percent And Joins: How?!

May 14, 2008

Hiya,
I have a need for a complex SQL statement to provide reporting information, but the SQL is way over my head and although I have some of the elements, I can't seem to pull them together to create a working SQL statement.
My database structure is as outlined below:

tblDef
------
ID IRVitems
ABC A1,A2,A3,A4,A5

tblIRV
------
ID IRVvalues
001 1,5,text1,10,3
002 2,1,text2,1,3
003 2,4,text3,1,1
004 1,4,text4,4,1
005 1,2,text5,4,1

tblLabel
--------
lblID lblVALUE lblTXT
A1 1 AAA
A1 2 BBB

I currently query tblDef to get IRVitems and in turn then query the other two tables to get statistical information to present in a report (via ASP).

For each item returned from IRVitems, I would like to report the spread and frequency of different values as follows:

A1
Value Label Count Percent
1 AAA 3 60
2 BBB 2 40

and then for A2, etc (although missing out A3 as it is a text item, but I can deal with that via ASP code beforehand). I would expect to have to hit the DB for each of the IRVitems (so once for getting the data for A1, againfor A2, etc).

I was provided a great bit of code to use SUBSTRING and GROUP BY to get this data (thanks zuomin), but I didn't consider the possible text values or numbers >9 when defining what I was trying to do (to be fair, they're new requirements):

SELECT SUBSTRING(IRVvalues, 1, 1) AS Value, COUNT(ID) AS Count
FROM tblIRV
GROUP BY SUBSTRING(IRVvalues, 1, 1)
ORDER BY value

which returns like this:

Value Count
1 187
2 163
3 2

Can I do a similar query to get all the info I need in one go? I saw the articale on a user-defined 'split' function (http://code.msdn.microsoft.com/SQLExamples/Wiki/View.aspx?title=StringArrayInput&referringTitle=Home) that can be used to split up the IRVvalues string to access the position I need in the array, but I'm a little clueless on how to then embed that into a SQl statement.
Can anyone point me in the right direction please?

Reporting Services :: Group And Sum Items / Sub-items Into One Record

Apr 10, 2015

I'm having an issue creating a report that can group & sum similar items together (I know in some ways, the requirement doesn't make sense, but it's what the client wants).

I have a table of items (i.e. products). In some cases, items can be components of another item (called "Kits"). In this scenario, we consider the kit itself, the "parent item" and the components within the kit are called "child items". In our Items table, we have a field called "Parent_Item_Id". Records for Child Items contain the Item Id of the parent. So a sample of my database would be the following:

ItemId | Parent_Item_Id | Name | QuantityAvailable
----------------------------------------
1 | NULL | Kit A | 10
2 | 1 | Item 1 | 2
3 | 1 | Item 2 | 3
4 | NULL | Kit B | 4
5 | 4 | Item 3 | 21
6 | NULL | Item 4 | 100

Item's 2 & 3 are child items of "Kit A", Item 5 is a child item of "Kit B" and Item 6 is just a stand alone item.

So, in my report, the client wants to see the SUM of both the kit & its components in a single line, grouped by the parent item. So an example of the report would be the following:

Name | Available Qty
--------------------------
Kit A | 15
Kit B | 25
Item 4 | 100

How I can setup my report to group properly?

May 30, 2007

Hi, all experts here,

Thank you very much for your kind attention.

I am trying to create a new mining structure with case table and nested table, the case table (fact table) has alread defined the relationships with the nested table(dimension table), and I can see their relationship from the data source view. But why the wizard for creating the new mining structure showed that message? Why is that? And what could I try to fix it?

Hope it is clear for your help.

Thanks a lot for your kind advices and I am looking forward to hearing from you shortly.

How To Add (pick And Choose) Items From One Table To Another

Jan 19, 2007

We have two tables (one has DTS import of external spreadsheet - the other is the online table)
The scenario is that I need to add items (from the first table) to the second table, when they don't exist. However, it's harder than that - the second table, in some fields has integers (ID field)), referring to another table (let's call it the 3rd table), but the first table has text (which is in the description, in the third table).
I have to run through the first table, row by row, checking the part number if it already exists in the second table - nothing happens, and it goes to the next line. In each line, if the part number does NOT exist, I need to insert the data in that row. BUT - remember that third table, for the item(s) in the first table with text, I need to dynamically query the third table, to get the ID, in order to complete the insert correctly (Select ID from Third Table where Description=@FirstTableFieldText)
I've never done anything like this, and I have no idea how to put this together - especially if it's all in one Stored Procedure. I need some help here on recommended ways to do it (and how)..... Even the base structure (pseudo code- whatever) would help

Table Items Custom Sort

Feb 15, 2007

hello

i am currently trying to port a "Business Objects" report to SQL Server Reporting Services.

in B.O., there is a possibility to define the order of the table values by previewing the table values and moving them up or down.

Example : the dataset contains data for 3 items, so in the Custom Sort window, I will see these 3 items and I can order them by moving them up or down in a listbox.

is this possible to do in Reporting Services ?

Help With Pulling Data Related To All Items In A Table

Jan 11, 2006

Hey guys,
I have created an asp.net page where users can select multiple items and then submit the form. I would like to return related items back. The catch is, I want to only return items that are related to all of the selected items.
I've created a SQL Procedure that puts each of the inputted item's ItemId in to a temp table, I have a second table called RelatedItems which I use as my junction table that has ItemId, and ReleatedItemId, I then have my Item table that has the data I want to get to (I've excluded this because I have no trouble pulling out data once I have an ItemId)
I can pull out all related ItemIds with a simple join, however I don't know where to start when it comes to pulling out only items related to all ItemIds in the @TempTable.
Any help or suggestions would be great.
Thanks,
Matt

Insert Items From One To Table To Multiple Smaller Tables

Nov 15, 2004

I have a table that I filled with data imported from another database.

What I need to do is now take this huge table and break apart the information and put it into 5 smaller tables.

So I have a huge insert statement.

I have one main table called Property with two keys. One key is a "Prop_ID" and the other is "owner" where Prop_Id is a automated unique ID. Once the information is inserted into that table, I then get the Unique ID that it was given, and I then used that ID to insert into the other tables.

The problem I am encountering is I keep getting the following error

Violation of PRIMARY KEY constraint 'PK_Prop_Res_Detail'. Cannot insert duplicate key in object 'Prop_Res_Detail'.
The statement has been terminated.

I have an idea what might be going wrong, but I am not sure. What I want to happen is that I want the query to look at the first row of the huge table and then do all 4 of the inserts, and then go to the next row. But I think it is trying to all the inserts into the property table, and then go on to the Prop_Res_Detail table and that is why I am getting that error.

Any help is greatly appreicated.

here is the code..

Code:

CREATE PROCEDURE [dbo].[Insert_Properties]

SQL 2012 :: Deadlock When Inserting And Deleting Items From Same Table

Nov 3, 2015

I am getting a number of deadlocks when inserting and deleting items from the same table.

The delete statement has a U lock and awaiting an IX lock on an index that covers the column in the where clause.

The insert statement has a IX lock and awaiting a U lock on the same index.

The delete statement is deleting about 5000 rows, where as the insert statement is inserting a single row.

Both these statements are found in stored procedures being called from LINQ to SQL.

I am wondering if there is a way I can prevent the delete statement taking the U lock out?My thinking being if the delete didn't take out the U lock then it would not deadlock with the insert. Are there any hints I could use to avoid the particular lock above?

I have seen various examples of multiple updates causing a deadlock, which can be fixed by adding multiple indexes. However, as I am inserting and deleting rows I imagine that all the indexes will need to be updated by both operations.

I have inherited the architecture and don't have the time to redesign everything at present. My backup plan is to deprioritize the delete and build in a retry mechanism.

However, it would be really good if I could find a more elegant way to handle deleting and inserting rows at the same time.

Deadlock trace information below...

When To Use A Nested Table?

Jul 19, 2007

Why would someone choose to model a problem with a case and nested table versus just using a case tables with multiple rows?

For example, a simple customer and product scenario where you could say:

Mining Model DT_CustProd
(
[Id] ,
[Gender] ,
[Age]
[Products] Predict
(
[ProductName] ,
[Quantity]
)
)

But you could also model as:

Mining Model DT_CustProd
(
[Id] ,
[Gender] ,
[Age]
[ProductName] Predict,
[Quantity] Predict
)

and just insert multiple rows per Id/Gender/Age? Is there any rule of thumb to use here when deciding to model with a nested table?

I understand that a nested table essentially pivots the data (http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=408840&SiteID=1) and the data becomes an attribute, but how do you know if you want that, or you want the data as a value of an attribute?

Why Use Nested Table?

May 17, 2006

Hi, all here,

I have a question about nested table use. I dont quite clearly see through why the nested table is very much necessary? I mean if we need information from both the current case table and nested table for mining models, we can just join both tables?

Thanks a lot in advance for any guidance and help.

Subtotals In Table (group Footer) Using Report Items 2005

Aug 31, 2007

How can I calculate a subtotal for a Report Item? I have a textbox(lets call it "PlusMinus") in the detail section of my table, which is a calculated textbox of two others (lets call them "Budget" and "Spent"). So, PlusMinus = (Budget - Spent). What I would like to do is get a subtotal for PlusMinus. I have tried several ways, using Sum() or RunningValue, even tried to write code, but I can't seem to get it right. Any ideas??

Thanks in advance!

DB Design :: Generate A Script To Choose Only Top 10 Items From Each Table In Database?

Aug 22, 2015

I know how to generate scripts that would contain insert queries of all records in all tables. But how can I limit this to top 10 records only from each table?I can select "Data Only" when generating the script, but it generates insert queries for all data. How can get the script to have only top 10 record insert statements? These top 10 should be ordered by the primary key.
