SQL 2012 :: Create View From Multiple Tables That Have 1 To M Relationship
Jul 31, 2014
I 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.
Now I want to create View that will have an exploded resultset based on SrvType.
For SrvType 1 and 2 there will be 2 lines per Itemid - One for 'Amount' anod another for 'Tax1+Tax2'. But for SrvType 3 there will be 3 lines per 'ItemId' - one for 'Amount', one for Tax1 and another for 'Tax2'.
I have a few hundred source records like this. Now sure how to achieve the exploded resultset with a View.
I want to create a view to get records from multiple tables. I have a UserID in all the tables. When I pass UserID to view it should get records from multiple tables. I have a table
UserInfo with as data as UserID=1, FName = John, LName=Abraham and Industry = 2. I have a Industry table with data as ID=1 and Name= Sports, ID =2 and Name= Film.
When I query view where UserID=1 it should return record as
Hi, 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 :
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
I have two tables, Inspections and InspectionDetails. The InspectionDetails only contains information if an inspection found violations. Some inspections don't look for violations so inspectiondetails would have no entry.How can I create a 0-Many relationship between these two tables?Inspection Table has : InspectionID, InspectionDate, TypeofInspection, Inspector..InspectionDetail Table has : DetailID (an auto-incrementing identity column), InspectionID, SectionViolated, ViolationDescription, InspectorNotes.
I'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.
I need to create a relationship between a local table and tables on alinked server. I used the design table wizard and selected therelationship property wizard. In the reslationship property wizard,the tables that I need to get the keys from in the linked server do notshow up. Is there a way to do this, or I simply don't have enoughpermission to tables in the linked server. On the local server, theSecurity tab of linked server property has Local Loging "sa", RemoteUser "sa" and Remote Password "****". Thanks for your help.
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.
I 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?).
I 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:
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?
Hi everyone,I have 5 servers, all with identical databases just different data. Ihave a rather lengthy SQL statement (in a View) to hit one database andpull-in certain data, but I'd like to somehow run this same SQLstatement within the view but hit all 5 servers so we don't have 5different versions of this data to mess with.I'm not opposed to creating an update query in a stored procedure tohit all 5 databases and update a table or even do this within a DTS,but I'd prefer to keep it as simple as possible and as dynamic so theusers can simply run the view and get live data anytime based on all 5tables.Is this possible ???Thanks,rlangly
I want to create a check constraint on a table but the constraint values depend upon another table column as well, now one possible way is to create a function to check the column value. But I don’t want to use the function.
Can I do this in a view if so then how can I achieve this.
I would like to create a view that joins these tables. Each row show a product and all the qualities it has, from quality 1 to quality 8. If there is no N'th quality, to show blank/null/zero.
The problem is how to get values from multiple rows (in table Qualities) in a single row in the view.
I've some AT_DATE tables (eg: AT_20080401, AT_20080402, ...) in SQLServer DB, and these AT_XX table have same columns. but table count could be variant, so I have to query sysobjects to get all of these tables. like this: select name from sysobject where name like 'AT_%'
Now I try to create a view AT which is the union of all these AT_XX tables, such as:
Code Snippet
Create View AT as select * from AT_20080401 union select * from AT_20080402 union ...
but since I'm not sure how many tables there, it would be impossible to write SQL as above. though I could get this union result via stored-procedure, view couldn't be created on the resultset of a procedure. Create View AT as select * from AT_createView() <-- AT_createView must be a function, not procedure
I've checked msdn, there is Multi-statement table-valued function, but this function type seems to create one temporary table, I don't want to involve much of insert operation because there could be more than 1million records totally in these AT_XX tables.
So is there any way to achived my goal? any reference would be appreciated, thanks !
I am running some new queries in SQL 2012 (in SSMS) and, while slow, they do run. If I try to use the same query to create a view it persists in timing out in about 30 seconds. I see very little on this subject via google.
PhoneType is an auxiliary table that has 5 records in it Home phone, Cell phone, Work phone, Pager, and Fax. Is there a way to do a join or maybe make a view of a view that would allow me to ultimately end up with…
StudnetID: 1 Name: John HomePhone: 123-456-7890 WorkPhone: 123-456-7890 CellPhone: Pager: 123-456-7890 Fax: Memo: This is one student record.
Some students will have no phone number, some will have all 5 most will have one or two. If possible I would like to do a setup like this in my database to keep from having to have null fields for 4 phone numbers that the majority of records won’t have. Thanks in advanced, Nathan Rover
1. As per my current development SQL Sever Analysis Database consists of two Cube (Cube A and Cube B). Cube A and Cube B share the same data source view (DSV1). The source for both these cubes has the same data source (DS1).
2. As per the requirement I need to create third Cube i.e. Cube C. Is it possible to create a second Data Source View (DSV2). The Source of second Data Source View (DSV2) will be the same data source(DS1).
I am thinking to create second Data Source View (DSV2) for Cube C because existing layout of the DSV1 has become complex. I wanted to know the pros and cons of creating a multiple data source view with same data source
Being still a relative newcomer to SQL Server (people may say I'm trying to take on too much being somewhat inexperienced once they read about the problem I'm trying to tackle, but alas...) I'm running into the following problem: I need to create tables in my user database on the fly (using Stored Procedures) so that each table can be created many times in the database but only once for every user. The tables should be named something like "username.Table1", "username.Table2" etc. as opposed to "dbo.Table1". I then want to use the stored procedure from .NET/C# in my web application, so that i can create the complete set of usertables for each of my clients.
Now, I tackled the stored procedure part (that is, it creates all the tables I need with all the parameters I want) and am able to use it from my web application (which took some time to learn but proved quite easy to do), but I cannot seem to get it coupled to the current user (instead of the dbo). Every time I trie, the tables are created as dbo.Table1 and when I try to create a new set, it gives a warning ("table with name such and so already exists..."). I made sure to log in as an authenticated user (using forms authentication) before trying to create the tables but this gives the aforementioned result.
What am I doing wrong? I use Visual Web Developer Express, SQL Server 2005 Express and IIS version 5.1
Searching the KB i only found links to SP1 and SP3, the server is already at SP3.
BOL says the following:
SQL Server 6.x :
Updatable views were restricted to modifications that affected only one table
SQL Server 2000:
Updatable views can modify more than one table involved in the view. The DELETE, INSERT, and UPDATE statements can reference a view as long as SQL Server can translate the user's update request unambiguously to updates in the base tables referenced in the view's definition.
So why can this view not be updated in SS2000 SP3 ?
FROM PS_PER_ORG_ASGN A ,PS_PER_ORG_INST C , PS_JOB D
WHERE A.EMPLID = C.EMPLID AND A.ORG_INSTANCE_ERN = C.ORG_INSTANCE_ERN AND A.EMPLID = D.EMPLID AND A.EMPL_RCD = D.EMPL_RCD AND D.EFFDT = ( SELECT MAX(EFFDT) FROM PS_JOB JOB2 WHERE D.EMPLID = JOB2.EMPLID AND D.EMPL_RCD = JOB2.EMPL_RCD AND (( JOB2.EFFDT <= { FN CURDATE() }) OR (JOB2.EFFDT > { FN CURDATE() } AND { FN CURDATE() } < ( SELECT MIN(J2.EFFDT) FROM PS_JOB J2 WHERE J2.EMPLID = D.EMPLID AND J2.EMPL_RCD = D.EMPL_RCD) ) )) AND D.EFFSEQ = ( SELECT MAX(EFFSEQ) FROM PS_JOB JOB3 WHERE JOB3.EMPLID = D.EMPLID AND JOB3.EMPL_RCD = D.EMPL_RCD AND JOB3.EFFDT = D.EFFDT )
I like to create an SQL view to divide amount 300,000 between 12 month starting from Month July 2014 to June 2015 as shown below
Amount Month Year 25,000 July 2014 25,000 August 2014 25,000 September 2014 25,000 October 2014 25,000 November 2014 25,000 December 2014 25,000 January 2015 25,000 February 2015 . . . .
SELECT e1.EntityIdentity as CompanyID FROM dbo.Entitye1 --company JOIN dbo.EntityAssociationea ON e1.EntityID = ea.EntityID1 JOIN dbo.Entitye2 --user ON ea.EntityID2 = e2.EntityID
This query occurs as a sub-query in many stored procedures where exists a WHERE clause that includes CompanyID IN (above query).
Since dbo.Entity and dbo.EntityAssociation change infrequently I thought that an indexed view would really improve performance. But I've found one of the seemingly undocumented Microsoft features when trying to create the clustered index and get the following error msg:
Msg 1947, Level 16, State 1, Line 1 Cannot create index on view "ROICore.dbo.vEntityEntityAssociation_CompanyUser". The view contains a self join on "ROICore.dbo.Entity".
I really need to improve performance on this subquery. Entity currently has over 20m rows and EntityAssociation over 35m rows and both are growing.
How to improve performance? Indexes on both tables for the most part give index seeks, but I thought my saviour might be the index view. Obviously this will not work.
I have read that I need to add an instead of trigger. I have no idea how to do this. I am basicaly trying to update at the moment but will also need to insert later. From the code in VWD2008 I only get the error when i include this info here: When i press update and these below are included in the update statement then i get the error.

I am trying to create multiple tables in a database using a SQL Script. First i want to find all the tables that have an Identity Column as a primary key in the database. Then for all the tables that meet the Identity Column and primary key criteria, I want to create a New Table.
For example if the Orders table has a Identity Column as a primary key, I want to Create a New Table called ProdID_Orders. The ProdID_Orders will have 1 column called ProdID.
If the OrdersDetails table has a Identity Column as a primary key, I want to Create a New Table called ProdID_OrdersDetails. The ProdID_OrdersDetails will have 1 column called ProdID.
If the Employee table has a Identity Column as a primary key, I want to Create a New Table called ProdID_Employee. The ProdID_Employee will have 1 column called ProdID.
so the Create Table Statement for the ProdID_Orders will look like this:
CREATE TABLE [dbo].[ProdID_Orders](
[ProdID] [int] NULL
) ON [PRIMARY]
The Create Table Statement for the ProdID_OrdersDetails will look like this:
CREATE TABLE [dbo].[ProdID_OrdersDetails](
[ProdID] [int] NULL
) ON [PRIMARY]
This sequence will continue for all the tables in the database that have an Identity Column as a primary key. Thanks. I will appreciate some assistance with this.
View or function 'MutualFund' is not updatable because the modification affects multiple base tables.
I get the above error when i try to delete rows from a view. i tried the following code with a table. it works perfectly. i want the same behaviour for a view. can anyone help.
Delete MutualFund from MutualFund inner join MutualFund_history on MutualFund.SecurityID= MutualFund_history.SecurityIDwhere MutualFund.MorningstarCategoryID=MutualFund_history.MorningstarCategoryID and MutualFund.MorningstarAssetClassID= MutualFund_history.MorningstarAssetClassID and MutualFund_history.insertdt =(Select MAX(DsegLastUpdated) from Timestamp_History(nolock))
"MutualFund" is a view. if it were a table, the above works well. but how can i simulate the same effect for a view. any help will be greatly appreciated.
I am new to SQL Server and I am trying to create a script / possible a cursor that will allow me to create multiple logins in one pass - without having to type each one.
I have 20 users USER1, USER2, USER3, USER4... but I can't seem to figure out how to get those users into a loop so I can end up with something like this.
CREATE LOGIN <user> FROM WINDOWS WITH DEFAULT_DATABASE=[master], DEFAULT_LANGUAGE=[English]......
I realize I can type this statement 20 times but perhaps there is a faster way -
