I have two tables
Books
-BookID
-CustomerID
Magazines
-MagazineID
-CustomerID
How would i write a single sql statement where i can get that counts how many bookIDs are listed for each custoemrID and how many magzaineIDs are listed for each customerID and have it return one table that looks like this:
CustomerID, BookCount, MagazineCount
I am trying to add 2 separate columns from separate tables i.e column1 should be added to column 2 when inserted and I want to use a trigger but i don't know the syntax to use...

I want to run a query that returns the count of records returned by two other queries. Having much trouble with this... I'm sure it's just a triviality. Thanks in advance...
I have 1 table that is just a list of feeds. A, B, C, D etc (15 rows in total) and each feed has other information attached to it such as Full name, location etc etc. I am only interested in the Feed column.
Each feed then has a corresponding data table which contains a list of records. Eg Feed A data is contained in TableA, Feed B data is contains in TableB and so on.
Basically what I need is a combined table that shows the list of Feeds in the 1st Column ( So A, B, C, D…..) and then a second column which counts the records from each separate data table corresponding to that feed.
So the end result would look something like this:
Feed------No of Records
A----------4 (from TableA)
B----------7 (from TableB)
C----------8 (from TableC)
D----------1 (from TableD)
Possible?
I am new to T-SQL and triggers
Any help will be appreciated
I am trying to change this code to insert firstname, surname (taken from employee table on db A) to firstname, surname on customer table of DB B but also create cust_id on customer table and DB B. currently I am getting all rows of customer.cust_id filled with the same data whenever a new data is inserted into (firstname,surmname of employee table)
Create trigger gen_cust_id ON employee for insert

We have some tables that we have spread across two databases. The segregation isn’t essential, but the entities involved were disparate enough that we thought it made sense. However, our client app regularly & frequently requires information that can only be answered by queries to tables in both databases. It has been suggested that segregating the tables as we have introduces a performance hit. At this stage, it would be relatively easy to re-combine the tables into one DB.
View 1 Replies View RelatedHello,
I am working with a database that among other things uses multipart keys as the unique indexes which are not consistent from say one table where a parent record resides to another table which contains related child records. For example I am working with two tables right now, one that contains content that I'll call Contents and the other which contains Usage information about the contents (number of view, a rating and comments give by a customer) which I'll call ContentsUsage. The system that manages the data for the tables has a versioning system by which, whn a content item is added (first time) a "unique" id (guid) and a version number of 1 is created along with the rest of data items in the Contents table and likewise in the ContentsUsage table (essentially a one to one mapping) on the like named fields in that table. Now, each time a given record in the Contents table is updated a new version, with the same guid is created in the Contents and ContentsUsage table. So one side I have:ContentGUID > AAAAVersion > 1ContentGUID > AAAAVersion > 2And the other table (ContentsUsage)ContentGUID > AAAAVersion > 1ContentGUID > AAAAVersion > 2
While both of these tables have a quasi-unique record (row_id) of type char and stored as a guid neither obviously are the same in the two tables and having reviewed the database columns for these tables I find that the official unique key's for these tables are different (table 1, Contents combines the ContentGUID and Version) as the composite / mutli-key index, while table ContentsUsage uses the RowGUID as it's unique index.
Contents RowGUID (unique key)ContentGUIDVersionViewsRatingComments................RowGUID ContentGUID (unique key)Version (unique key)Description.....
Bearing this in mind I am unable of course to link directly the two tables by using the just the ContentGUID and have to combine the additional Version to I believe obtain the actual "unique" record in question. The question is in terms of writing queries, what would the most efficient query be? What would be the best way to join the two in a query? And are there any pitfalls with the current design that you can see with the way this database (or specifically these tables are defined)? It's something I inherited, so fire away at will on the critique. Having my druthers I would have designed these tables using a unique key of type int that was autogenerated by the database.
Any advice, thoughts or comments would be helpful.
Thanks,P.
I've read that if particular tables are frequently queried together through a join then these tables should be placed on different devices on different physical disks.
What does this mean exactly and how would you configure this?
Is this a common practice in high-performance real-world environments (or should it be)?
I would like to 'one table' record to separate 'two or three tables'
. I just know use the DTS , try to import and export again and agian.
So trouble.
Could you give me some suggestions for me? For example ,
'Cursor' write in new table . But I try to SQL Server Books Online
which is not suitable for me solving problems. One table separate two
or three tables. Can you wirte the detail example for me?
Thx a lot.
Hi,
We are building an application for online system for people to place ADs for selling various used items like Car, Electronics, Houses, Books etc.
If someone selling a car then he can fill out headline, year, make, model, mileage, transmission, condition, color, price, description, contact etc.
Similarly if someone selling a digital camera he will fillout headline, memory, zoom, megapixel, maker, model, color, batter, description etc.
Option 1: I can have a main table to hold the common attributes of all different types of ADs (headline, images, contact, price, color, condition, description)
+ 1 table to store string values of all ADs (car: maker, model, square feet (if house), memory, megapixel (camera) etc)
+ 1 table to store the droplist select values(car: transmission, door, seat etc; house: year_built)
pros: single table for all ADs. unique IDs for all ADs, easy to extend as new attributes can be dropped easily.
cons: lot of physical reads of 2nd and 3rd table from join. 10 times physical reads compared to option 2 when reading 5000 records.
Option 2: have different set of table for each AD type. Car will have its own main table + 1 table to store multiselect list box values.
Similarly housing will have its own set of tables
pros: 10% less physical read than option 1.
cons: hard to add new attributes. We have to modify the main table by adding one column.
Query will go to different table based on the category.
Do you have any suggestions on which way to go?Thanks
We have a large Datawarehouse and the size is 50TB.. The tables are placed in filegroups based on the schema like fact, dimensions, raw data each sit on seperate filegroups. I am thinking will it make sense to seperate the large facts which are having billions of rows so that they reside on filegroups on their own..
View 9 Replies View RelatedI am trying to tie together tables that show quantities of a product committed to an order and quantities on hand by a location.

I have a report that's created each day as a flat textfile.Because I came from the Access world, I created a macro that importsit with a schema that gives meaningful names to the various columns,and then uses a query to massage some of the data for me (deletes thefirst blank row and does a couple of calculations)Then I use DTS to import the Access query as a table.the textfile has a column called "File_num", and among several others,a column called "Serial_num". (the file numbers represent shipments,and sometimes there are more than one serial number in the shipment,etc., so there is a separate line for every serial number)Naturally, I would like to split this info into two tables..one thatdoes not contain the serial numbers and has a primary key on the"File_num" column, and another table that would contain just the"File_num" and "Serial_num" columns. That way I could relate themlater...but most importantly, it will give me a table where I can usethe "File_num" as my primary key.What would be the best way to import these two tables from one sourcetextfile? The other thing that gives me problems is that the textfile has no column names, and the first row is always blank.I'm very new to SQL and DTS and would appreciate any direction.Thanks,Larry- - - - - - - - - - - - - - - - - -"Forget it, Jake.

I would like to update DB2.dbo.Suppliers2 based on values from DB1.dbo.Suppliers1 joining on SUPPL1_ID = SUPPL2_ID.
How can I do this in SSIS?

What is example of best method to do this ?
Currently we have one customer database containing various tables. As part of requirements for a new client, we need to manage their data in a totally separate database. The tables and structure are exactly the same but we would be loading data into a separate database.
I am looking for a way to combine tables with the same name in each database when I run queries, rather than having to query each database separately. Currently we actually have many queries set up in MS Access which use an ODBC link to query the data off SQL server. I am aware it is possible to apply a UNION SELECT in Access from 2 separate ODBC connections, but this is extremely slow.So my initial question is - is there a way to provide access to the tables from both databases over the same ODBC link? If this cannot be done over ODBC I guess we can consider more "modern" methods, but ideally we want to keep this in MS Access as that is where our existing queries are based. I was hoping that some kind of view can be treated as an ODBC connection.I mentioned ideally we want to keep the reporting queries in MS Access.
From my query I am getting results like below in one of the column:
'immediate due 14,289.00
04/15/15 5,213.00
05/15/15 5,213.00
06/15/15 5,213.00
07/15/15 5,213.00
08/15/15 5,213.00
09/15/15 5,213.00
10/15/15 5,213.00
11/15/15 5,210.00'
this same type of many rows are there (i just mentioned one) but having same pattern with tabs as delimiter in between dates and amount.
I need something that shows Date on one side representing particular amount on the other
For Immediate Due it will be current date and the amount besides it.
how can I achieve this.
How can i format my query so that each piece of data appears on a new separate line? Is there a command for a new line feed? does not work.
thanks.
For example:
a: data
b: data
c: data
a: data
b: data
c: data

Hi all....
Have a bit of a dilema involving getting a count on an inner join table select.
The projects (WU_Title) are listed in one table (BPI_Upload) and the second table (BPI_ProjectFeedback) holds multiple rows that are added via form where PF_Project is the same as WU_Title.
Here is the current select I am using...
---------------------------------------
SELECT t1.FileID, t1.WU_Title, t1.WU_Start, t1.WU_End, t1.WU_ProjectStatus, t2.PF_Project
FROM dbo.BPI_Upload t1 INNER JOIN dbo.BPI_ProjectFeedback t2
ON t1.WU_Title = t2.PF_Project
WHERE t1.WU_ProjectStatus = 'Completed'
--------------------------------------
This presently returns:
----------------------------------
ID(1)Project(t1) ID(2) Project(t2)
1 project_a 1 project_a
1 project_a 2 project_a
1 project_a 3 project_a
---------------------------------
What I need is to return only the title and a count from the second table of how many times the title occurs there.
Ultimately ....
Title[project_a] Count[3]
I am having difficulty with where to place the COUNT() within the select.
Any suggestions would be appreciated.
Thanks...
Does anyone know how to get the row count of a user table by using the system tables.
There is no guarantee that these user tables will have any indexes - so I can not use the sysindexes table to count the rows in a clustered index.
Is there another way?
Hello To All @ Dev Shed,
I have three tables, say, A, B, and C. Both B and C contain/reference the primary key of A, ie B.a_id, and C.a_id. Multiple rows in B and multiple rows in C can have the same a_id. C and B have no relationships and essentially independant of each other.
I'm trying to find a single query (to prevent having to rewite function interfaces) that can return all the fields of A, the sum of a feilds in B, B.cost, where B.a_id = A.a_id and finially the count of C.a_id 's for where C.a_id = A.a_id.
The query I've been worlking on so far is as follows,
SELECT A.name, A.a_id, SUM (B.cost), COUNT ( DISTINCT C.a_id)
FROM A LEFT JOIN B USING (a_id) LEFT JOIN C USING (a_id)
GROUP BY A.a_id
This produces the correct result for the count of C.a_id (thanks to a DISTINCT) but the sum of B.cost is out by the factor of count C.a_id. I can see why this is happening but have completely run out of ideas. Group by on two columns may be? A strategically placed subquery? Is is even possible?
Any help would be much appreciated. Thanks in advance for your time.

PS I'm new to this forum thing so if you want the unsimplified query with all the full names just let me know and I'll post it.
Hi,
I have three tables - clients, messages, orders. clientid is the primary key for clients and clientid is present in both messages and orders as foreign key. I want to get clientid, messagecount, and ordercount, that is, for each client I want to get number of messages posted by the client and number of orders placed by the client.
To get clientid, messagecount I do this:
select a.clientid, count(b.clientid) as messagecount
from clients a left outer join messages b on a.clientid = b.clientid
group by a.clientid
To get clientid, ordercount I do this:
select a.clientid, count(b.clientid) as ordercount
from clients a left outer join orders b on a.clientid = b.clientid
group by a.clientid
But I am not able to get all three clientid, messagecount, ordercount in a single query. This is what I tried. But it is not giving me the correct answer.
select a.clientid, count(b.clientid) as messagecount, count(c.clientid) as ordercount
from clients a
left outer join messages b on a.clientid = b.clientid
left outer join orders c on a.clientid = c.clientid
group by a.clientid
Can any one tell me how to do it right?
Thanks.
I'm starting with the question but my end would be to store the results of this data so I can query it from my Access front end using between dates to determine totals.
1) How do I create a SQL view/temp table to query count totals from an MS Access 2010
2) CREATE TABLE [dbo].[tblProject](
[ProjectID] [int] IDENTITY(1,1) NOT NULL, [CAD] [bit] NULL, [RMS] [bit] NULL, [JMS] [bit] NULL,
and
CREATE TABLE [dbo].[tblProjectMilestones]([MilestoneID] [int] IDENTITY(1,1) NOT NULL, [ProjectID] [int] NULL, [ProjectSignedByCustomer] [datetime] NULL,
[ProjectCompleted] [datetime] NULL,
3) tblProject - CAD, RMS and JMS = True/False variations
tblProjectMilestones - ProjectCompleted = datetime
4) To calculate the count for each deliverable with no dates:
Select (Select COUNT (*) as CountCAD from tblProject where CAD='true') as CADNumber,
(Select COUNT (*) as CountRMS from tblProject where RMS='true')as RMSNumber
5) When I run the query between any dates, using tblProjectMilestonses.ProjectCompleted, what I would like is:
Code:
CADCount | RMSCount| JMSCount|

Hello. I'm quite new to SQL so have included as many details as i can think of here. The scenario is a wordsearch style puzzle. The user can select their answers in any order and these answers are stored in a table. I need help with the UPDATE statement to compare the users answers against the correct answers for that puzzle.
(Note: In the actual scenario there will be 10-15 answers per grid, but i have reduced the number to make testing easier - hopefully the code for a working UPDATE statement will be scalable to account for grids with different numbers of answers etc.)
The Tables:
-- These are the correct answers for a given grid (gridid).
-- Due to the nature of the puzzle, answers can be in any order.
-- Each level may contain one,two,or no 'bonusanswers' which are harder to find, so these are scored separately so bonus points can be awarded.
CREATE TABLE correctanswers
(
gridid smallint IDENTITY(1,1)PRIMARY KEY CLUSTERED,
answer1 char(15),
answer2 char(15),
bonusanswer1 char(15),
bonusanswer2 char(15)
)
-- These are the user submitted set of answers 'answerid' for level 'gridid'.
-- Answers may be submitted in any order.
CREATE TABLE useranswers
(
answerid smallint IDENTITY(1,1)PRIMARY KEY CLUSTERED,
gridid smallint,
firstanswer char(15),
secondanswer char(15),
thirdanswer char(15),
fourthanswer char(15),
)
-- A user (userid) submits their answers which get stored as answerid.
-- This table shows the scores for each set of answerid's the user has submitted.
-- A high score table for both the individual user, and all users may be created using this table.
CREATE TABLE userscores
(
userid smallint,
answerid smallint,
mainmatches smallint,
bonusmatches smallint
)
The Test Data:
-- sample test data
-- 2 users userid's '1' and '2' each have two goes on level1 (gridid 1)
-- correct answers for gridid 1
INSERT INTO correctanswers (answer1, answer2, bonusanswer1, bonusanswer2) VALUES ('cat','dog','rabbit','elephant')
-- user submitted answers for gridid 1
INSERT INTO useranswers (gridid, firstanswer, secondanswer, thirdanswer, fourthanswer) VALUES (1,'dog','rabbit','horse','cow')
INSERT INTO useranswers (gridid, firstanswer, secondanswer, thirdanswer, fourthanswer) VALUES (1,'dog','cat','elephant','horse')
INSERT INTO useranswers (gridid, firstanswer, secondanswer, thirdanswer, fourthanswer) VALUES (1,'rabbit','cat','elephant','donkey')
INSERT INTO useranswers (gridid, firstanswer, secondanswer, thirdanswer, fourthanswer) VALUES (1,'horse','cat','dog','sheep')
-- scores for users attempts - columns 3 and 4 needs calculating
INSERT INTO userscores VALUES (1,1,null,null) -- one main answer and one bonus answer, so null,null should be 1,1
INSERT INTO userscores VALUES (1,2,null,null) -- two main answers and one bonus answer, so null,null should be 2,1
INSERT INTO userscores VALUES (2,3,null,null) -- one main answer and two bonus answers, so null,null should be 1,2
INSERT INTO userscores VALUES (2,4,null,null) -- two main answers and no bonus answers, so null,null should be 2,0
I have included the correct new table values for the sample data - basically filling in the two null fields in the 'userscores' table.
I haven't used SQL much but from the little i know then i think the answer will include JOIN, COUNT and IN statements as part of the UPDATE statement...but i haven't a clue where to start with the order/logic etc.
I have looked for sample solutions myself but all the examples i have found so far are to do with exact matches between two tables, whereas in my scenario i need to know how many matches, irrelevant of the order.
Many thanks.
