Multiple Tables Without Relationship
Mar 16, 2007I'm building a Search Function with different pull down options. I have 9 Tables and 6 of them are not related.
How do I build an effecient SELECT?
Thanks I'm somewhat new to MSSQL.

Page 3 - Multiple Tables Without Relationship
Mar 20, 2007Inner join vs outer join:
Inner join will remove rows from the first table if there is not a corresponding row in the 2nd table. Outer join will keep the rows, and use all NULL values to fill in the gaps in the 2nd table.
In general outer joins are more likely to grow a result set and inner joins are more likely to shrink one (though that will depend on the data and the query). For this reason, it is usually better when building complex queries to try to do your inner joins before your outer joins, because then you will keep your result set smaller for longer and thus the later joins can run faster.
Help With INSERT Multiple Tables In Many-to-many Relationship?
Feb 2, 2006I am relatively new to MS SQL (not a novice, but hardly a master).
I am working on a content management application for a magazine publisher. It’s written in ASP (VB Script) and being created on Dreamweaver 8 with an MS SQL 2000 database. Now, I’m trying to decide the best and fastest approach to coding a complex INSERT and UPDATE function. My question isn’t as much about the SQL (although that will probably come up after I decide how to do this), but about the procedural steps and approach I shuold be taking to do this.
Reporters will use an online form to enter their story into the system. It collects the usual data: Headline, byline, story content, and the story category (feature, opinion, entertainment, business, sports, etc.). Each story may belong to MULTIPLE categories (feature & business, for example).
So, I’ve created three tables to support this many-to-many realtionship:
Story
Category
StoryCat (a junction table with the IDs from both the other tables).
The online form has a dropdown menu which pulls the available categories from the Categories table. When the reporter has entered the data I use ASP to performs the insert just as you would expect it to.
The next step needs to be to update the StoryCat table so that it creates a new record with the StoryID of the record it just inserted, along with the CategoryID that was in that record.
------------------
As I said, I’m not sure of the best way to do this.
Should I just pull back the last record inserted and then create a procedure that would insert into the StoryCat table (which is what I’m thinking of doing on the confirmation page), or is there another approach I should take (perhaps some sort of temporary table or stored procedure?).
Any and all help will be greatly appreciated.
Power Pivot :: Multiple Relationship Between Same Tables
Sep 8, 2015I am developing a database in PowerPivot and I am wondering how to create many relationships between the same 2 tables. All relationships must be active.
Let me give you a DUMMY example: let's say that the database has 2 tables, the Employee table and Manager table:
->Employee Table: Employee_name, Previous_Manager, Current_Manager
->Manager Table: Manager_Name
Because I have 2 manager fields in the employee table, I need to create 2 links between the employee and manager tables:
-> Link 1: Previous_Manager ---- Manager_Name
-> Link 2: Current_Manager ---- Manager_Name
Right now, one of the links is inactive...
Is there a way in PowerPivot to create 2 active links like that ?
I have Power Pivot version 11.0.3000.0 on Excel 2010 on Windows 7
SQL 2012 :: Create View From Multiple Tables That Have 1 To M Relationship
Jul 31, 2014I have two table studenTtable and courseTable which is each student take more than one course . 1:M...for example Student1 take 2 courses (C1 , C2). Student2 take 3 courses (C1,C2, C3).I need to create a table/View that contain student information from StudentTable plus all the courses and the score for each course from CoursTable in one row.
for example Row1= Student1_Id ,C1_code ,C1_name ,C1_Score ,C2_code,C2_name ,C2_Score Row2= Student2_Id,C1_code, C1_name,C1_Score,C2_code ,C2_name ,C2_Score , C3_code,C3_name,C3_Score
and since Student one just have two courses , I should enter NULL in 'Course 3 fields'.My Struggle is in the insert statement I tried the following but it show an error
Insert Into Newtable ( St_ID, C1_code,c1_name, C1_Score ,C2_code ,C2_name,C2_score,C3_code ,C3_name,C3_score)
Select (Select St_ID from StudentTable) , (Select C_code,c_name,c_Score from Coursetable,SudentTable where course.Stid =Studet.stid) , (Select C_code,c_name,c_Score from course ,student where course.Stid =Studet.stid ), (Select C_code,c_name,c_Score from course ,student where course.Stid =Studet.stid );
I'm fully aware that the New table/View will break the rules of normalization ,but I need it for specifc purpose.I tried also the PIVOT BY functionality but no luck with it .I also tried writing a code using Matlab (because it is high level sw that it is easy to learn for people not expret in programming as me) but didn't know how to combine the Student and Courses Matrices in my loop.

Combing Two Tables With No Relationship
May 8, 2007Which way to go?
Have two separate programs(Visual Studio-Coded in Visual Basic) that share the same sql 2005 database(called Night Audit)
The tables are called RoomSettlement and Settlement.
They were separate tables and separate programs in the past because it was just exported in excel to a visual integrator that dumped the amounts into our accounting software.
Now needing to combine the two tables(that have no link) on to a single excel sheet daily where the tables have the same date:
Table: Room Settlement – Field: RoomSettlementDatetxt =
Table: Settlement – Field: SettlementDatetxt
Any Ideas on the best way to go? (Link the tables with a foreign key and primary key, maybe union based on date, or any easier suggestion with out having to change a lot of the program )

SQLCE V3.5: Single SDF With Multiple Tables Or Multiple SDFs With Fewer Tables
Mar 21, 2008Hi! I have a general SQL CE v3.5 design question related to table/file layout. I have an system that has multiple tables that fall into categories of data access. The 3 categories of data access are:
1 is for configuration-related data. There is one application that will read/write to the data, and a second application that will read the data on startup.
1 is for high-performance temporal storage of data. The data objects are all the same type, but they are our own custom object and not just simple types.
1 is for logging where the data will be permanent - unless the configured size/recycling settings cause a resize or cleanup. There will be one application writing alot [potentially] of data depending on log settings, and another application searching/reading sections of data.
When working with data and designing the layout, I like to approach things from a data-centric mindset, because this seems to result in a better performing system. That said, I am thinking about using 3 individual SDF files for the above data access scenarios - as opposed to a single SDF with multiple tables. I'm thinking this would provide better performance in SQL CE because the query engine will not have alot of different types of queries going against the same database file. For instance, the temporal storage is basically reading/writing/deleting various amounts of data. And, this is different from the logging, where the log can grow pretty large - definitely bigger than the default 128 MB. So, it seems logical to manage them separately.
I would greatly appreciate any suggestions from the SQL CE experts with regard to my approach. If there are any tips/tricks with respect to different data access scenarios - taking into account performance, type of data access, etc. - I would love to take a look at that.
Thanks in advance for any help/suggestions,
Bob
How To Create A Datagrid For Two No Relationship Tables
Jan 13, 2004Hi, I am trying to create a create for two table A and table B which have no relationship each time. For TableA, there are 3 columns like ID, APoints1, APoint2. For Table B, there are also 3 columns as ID, Qty, BPoints. There is no internal relationship for these two tables. But there may be same ID inside A and B for some records. Now I want to create a datagrid for displaying the information as :
ID, Sum(A.APoints1 + A.APoints2) - Sum(B.Qty * B.BPoints) WHERE A.ID = B.ID
Please Notice that I can't use directly SQL script as following from table A and table B because there is no relationship for Table A and Table B, otherwise the recult set would be wrong:
Select A.ID, Sum(A.APoints1 + A.APoints2) - Sum(B.Qty * B.BPoints) WHERE A.ID = B.ID group by A.ID
May I know is there solution for it?
Thank you very much!
Index & FK Relationship On LookUp Tables
Jun 11, 2007Hi!
It's been always said that it is best to put index on commonly joined fields in the table. But putting too much index on the table would cause the table to be slow on insert and update.
My question is, how do you deal with your fields that uses look up tables? Like for example for these fields
- CountryID(smallint)
- CreatedBy(int)
- ModifiedBy(int)
- Status(tinyint)
Those fields don't come a big part in the table, though when I query the table I always join them with their respective primary table to get their respective text value. Do I still need to put Index & FK relationships to these fields?
What fields are normally good candidates for index or fk relationships?
Thanks,
Enzo
Relationship Between Inserted And Deleted Tables?
Jul 30, 2007Hi all,
I just ran across an issue on a SQL 2000 sp4 db where RI was being maintained solely with triggers. I am attempting to change the primary key of a parent table and cascade the results to all its children without using the vendor-supplied trigger code (long story...) using an INSTEAD OF trigger.
My question is: does SQL Server create any kind of relationship between the inserted and deleted tables that I could exploit since the key field is unavailable?
I am trying to avoid having to add a surrogate key to each of the children just for this activity (as there are many M rows in each and no other suitable unique column combinations that span all the child tables).

SSIS And Parent-Child Relationship Tables
Jun 15, 2006Supose I have two records in a parent-child relationsuip (actually I have many more such records). Does SSIS offer any support ask for inserting one record into the parent table, the other into the child table, and updating the foreign key of the child to point to the parent?
TIA,

P.S. I have to do just this as part of the datawarehouse test I'm running. Seems like a common task but I don't recall anything in SSIS addressing the issue.

Retrieving The Tables Relationship From SQL Server Database Diagrams
May 26, 2004Hi All,
Currently i am defining a simple relationship between
Customers->Orders->Order Details through the Database Diagrams feature in
the SQL 2K. Using the Server Explorer, i can see the Database Diagrams, but
when i try to "drop" the Database Diagrams into the page, it gives the error
message.
I would like to know the procedures to retrieve the database relationships
from Database Diagrams and manipulate them through ADO.NET
I prefer to "convert" already defined relationship using SQL Server Database
Diagrams into XSD file or probably there is another method to "read" those
relationship and manipulate them.
Thank you very much for all your help

Inserting Data Into Two Tables With Parent-child Relationship

When I try to run the package, the package will just seems to hang up in bids. I have found two ways around the issue but I don't like either approach. Is there a way to set which table gets insert first?
If I uncheck the check constraints option on the child table, the package will run very quickly but this option alters the child table and basically disables the constraint. I don't like this option because it is altering the database.
The second approach is to set the commit level on both tables to say 10,000 and make sure that the multicast component has the first output path moved to the parent table. I don't like this option because I am not sure if the records are backed out if the package should abend after records have been committed.
Reporting Services :: How To Create 2 Tables With Primary / Foreign Key Relationship

View 5 Replies View RelatedHow Can I Create A One-to-one Relationship In A SQL Server Management Studio Express Relationship Diagram?
Mar 25, 2006How can I create a one-to-one relationship in a SQL Server Management Studio Express Relationship diagram?
For example:
I have 2 tables, tbl1 and tbl2.
tbl1 has the following columns:
id {uniqueidentifier} as PK
name {nvarchar(50)}
tbl2 has the following columns:
id {uniqueidentifier} as PK
name {nvarchar(50)}
tbl1_id {uniqueidentifier} as FK linked to tbl1.id
If I drag and drop the tbl1.id column to tbl2 I end up with a one-to-many relationship. How do I create a one-to-one relationship instead?

Power Pivot :: Use Relationship Not Overriding Conflicting Active Relationship?
Oct 14, 2015I have four tables with relationships as shown. They have a circular relationship and so one of the relationships is forced to be inactive.
Operation (Commodity, OperationKey) ==========>
Commodity (Commodity)
/
/
|
|
Advice (OperationKey) ====== (inactive)=======>
Operation Commmodity (Commodity, OperationKey)
I have the following measure:
Advice No. Commodity:=CALCULATE (
COUNTROWS ( 'Advice' ),
USERELATIONSHIP(Advice[OperationKey],'Operation Commodity'[OperationKey]),
operation
)
However, the userelationship function does not override the active relationship between Operation & Advice and so the measure is limited to Advices directly filtered by the Operation table.
If I delete the relationship between Operation and Advice, then the measure works as expected i.e. Operation indirectly filters Operation Commodity which filters Advice.

Import Csv Data To Dbo.Tables Via CREATE TABLE && BUKL INSERT:How To Designate The Primary-Foreign Keys && Set Up Relationship?
Jan 28, 2008Hi all,
I use the following 3 sets of sql code in SQL Server Management Studio Express (SSMSE) to import the csv data/files to 3 dbo.Tables via CREATE TABLE & BUKL INSERT operations:
-- ImportCSVprojects.sql --
USE ChemDatabase
GO
CREATE TABLE Projects
(
ProjectID int,
ProjectName nvarchar(25),
LabName nvarchar(25)
);
BULK INSERT dbo.Projects
FROM 'c:myfileProjects.csv'
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = ''
)
GO
=======================================
-- ImportCSVsamples.sql --
USE ChemDatabase
GO
CREATE TABLE Samples
(
SampleID int,
SampleName nvarchar(25),
Matrix nvarchar(25),
SampleType nvarchar(25),
ChemGroup nvarchar(25),
ProjectID int
);
BULK INSERT dbo.Samples
FROM 'c:myfileSamples.csv'
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = ''
)
GO
=========================================
-- ImportCSVtestResult.sql --
USE ChemDatabase
GO
CREATE TABLE TestResults
(
AnalyteID int,
AnalyteName nvarchar(25),
Result decimal(9,3),
UnitForConc nvarchar(25),
SampleID int
);
BULK INSERT dbo.TestResults
FROM 'c:myfileLabTests.csv'
WITH
(
FIELDTERMINATOR = ',',
ROWTERMINATOR = ''
)
GO
========================================
The 3 csv files were successfully imported into the ChemDatabase of my SSMSE.
2 questions to ask:
(1) How can I designate the Primary and Foreign Keys to these 3 dbo Tables?
Should I do this "designate" thing after the 3 dbo Tables are done or during the "Importing" period?
(2) How can I set up the relationships among these 3 dbo Tables?
Please help and advise.
Thanks in advance,
Scott Chang
Integration Services :: Import Multiple Files Into Multiple Tables Using SSIS
Jun 16, 2015I have a requirement where in i have around 15 different flat files , filenames are fixed but folder path can be changed(i think i should use a variable for folder path). These 15 files data should go to their respective tables in the database.
Whether I need to create separate data flow task for each file or separate package? In addition to these, example : while importing product data into product table, if product ID already exists, we need to ignore it and upload only the new records.
Integration Services :: Import Data From Multiple Excel Sheets To Multiple Tables Using SSIS?
Aug 25, 2015I have an excel file that has multiple sheets and I need to import data from each separate sheet to a separate table using SSIS.
E.g. Sheet A data should go to Table A and Sheet B data should go to Table B and so on. Is it possible to do this with out using script task.
One Receipt Number, Query Multiple Tables Gives Multiple Data.
Sep 8, 2006I have just taken over the job of sorting out a rather poorly designed database. It looks like it was 'upsized' from an access database to the SQL server. The SQL server is the 2000 version.
Now I am trying to generate a report of what the students in the database are owing by referencing the Receipt table and then all the available payment methods and allocations. I was wondering if there was anyway to work out data being displayed twice (Let me demonstrate)
Note1: All the tables are linked by a key of ReceiptNo. From what I can see there is a table for every payment type and allocation but no link between the two other then the receipt number.
Using the query:
SELECT T_Receipt.ReceiptNo, T_cheque.Amount AS Chq_Amount, T_credit.Amount AS Cre_Amount, StandingOrder.Amount AS Stn_Amount,
T_BankTransfer.amount AS Bnk_Amount, T_cash.TotalAmount AS Cas_Amount, T_RentPayment.AmountPayed AS Ren_Paid,
T_AdminPayment.AmountPaid AS Adm_Paid, T_InternetBilling.Total AS Int_Paid, T_Utilities.AmountPaid AS Util_Amount,
T_InvoicePayment.amountPaid AS Inv_Paid, T_OtherPayments.paymentAmount AS Oth_Paid, T_parkingBill.paymentAmount AS Prk_Paid,
T_TelephoneBills.TelephoneCredit AS Tel_Paid, T_DepositPayment.[Deposit payment] AS Dep_Amount, T_Receipt.cancelled AS Canceled,
T_Receipt.RemittanceReceiptNo AS Rec_Ref, T_Receipt.Student
FROM T_Receipt INNER JOIN
T_DepositPayment ON T_Receipt.ReceiptNo = T_DepositPayment.receiptNo LEFT OUTER JOIN
T_RentPayment ON T_Receipt.ReceiptNo = T_RentPayment.RentPaymentNo LEFT OUTER JOIN
StandingOrder ON T_Receipt.ReceiptNo = StandingOrder.ReceiptNo LEFT OUTER JOIN
T_TelephoneBills ON T_Receipt.ReceiptNo = T_TelephoneBills.ReceiptNo LEFT OUTER JOIN
T_parkingBill ON T_Receipt.ReceiptNo = T_parkingBill.ReceiptNo LEFT OUTER JOIN
T_OtherPayments ON T_Receipt.ReceiptNo = T_OtherPayments.ReceiptNo LEFT OUTER JOIN
T_InvoicePayment ON T_Receipt.ReceiptNo = T_InvoicePayment.receiptNo LEFT OUTER JOIN
T_cash ON T_Receipt.ReceiptNo = T_cash.ReceiptNo LEFT OUTER JOIN
T_AdminPayment ON T_Receipt.ReceiptNo = T_AdminPayment.ReceiptNo LEFT OUTER JOIN
T_BankTransfer ON T_Receipt.ReceiptNo = T_BankTransfer.receiptNo LEFT OUTER JOIN
T_Utilities ON T_Receipt.ReceiptNo = T_Utilities.receiptNo LEFT OUTER JOIN
T_credit ON T_Receipt.ReceiptNo = T_credit.ReceiptNo LEFT OUTER JOIN
T_cheque ON T_Receipt.ReceiptNo = T_cheque.ReceiptNo LEFT OUTER JOIN
T_InternetBilling ON T_Receipt.ReceiptNo = T_InternetBilling.ReceiptNo
GROUP BY T_Receipt.Student, T_Receipt.ReceiptNo, T_cheque.Amount, T_credit.Amount, StandingOrder.Amount, T_BankTransfer.amount, T_cash.TotalAmount,
T_AdminPayment.AmountPaid, T_InternetBilling.Total, T_Utilities.AmountPaid, T_InvoicePayment.amountPaid, T_OtherPayments.paymentAmount,
T_parkingBill.paymentAmount, T_TelephoneBills.TelephoneCredit, T_Receipt.cancelled, T_Receipt.RemittanceReceiptNo,
T_DepositPayment.[Deposit payment], T_RentPayment.AmountPayed, T_Receipt.Student
HAVING (T_Receipt.Student LIKE N'06%')
Which gives a result of:
RecNo.
30429
Cheque
250
Deposit
250
30429
679.98
250
This is fine but when I do analysis on this it appears as though the student has paid two deposit payments. I was wondering with out querying each table independently from an application if there was a criteria to specify that I only get one deposit result.
So as such say, give me all the payments but I only want one result from the other tables. I though about discrete but that wouldn't work here.
Merging Data From Multiple Databases With Multiple Tables (all With The Same Structure)
Nov 15, 2006Hi!
I have 7 source databases and one target database, all using the same structure. The structure is made of 10 tables, with foreign key constraints.
I need to merge the source databases into the target (which won't have any data before that process, but will already have the correct schema), and to keep the relationships between the records.
I know how to iterate over the source databases (with SMO foreach), but I'd like to know if someone can advise the best copy method for that context in SSIS ? (I don't want to keep the primary keys, but I need to keep the relationships...)
Any pointer most welcome!
best regards and thanks

Importing Multiple Flat Files To Multiple Tables In SSIS
Jun 27, 2006I have a couple of hundred flat files to import into database tables using SSIS.
The files can be divided into groups by the format they use. I understand that I could import each group of files that have a common format at the same time using a Foreach Loop Container.
However, the example for the Foreach Loop Container has multiple files all being imported into the same database table. In my case, each file needs to be imported into a different database table.
Is it possible to import each set of files with the same format into different tables in a simple loop? I can't see a way to make a Data Flow Destination item accept its table name dynamically, which seems to prevent me doing this.
I suppose I could make a different Data Flow Destination item for each file, in the Data Flow. Would that be a reasonable solution, or is there a simpler solution, or should I just resign myself to making a separate Data Flow for every single file?
