Hi,
I need help in creating a trigger before delete. The trigger should be in such a way that it should display a message, if there is any relationship with other table.
For example I have a table with employee details which have empid as primary key. I have another table with employee salary details where empid is foreign key. The trigger should check the relationship with these two tables. If I try to delete an emploeyee from employee details table and if there is a relationship of that employee with the salary table then the trigger should print a message. If there is no relationship then the trigger should perform the deletion.
I want to create a trigger like this.
Here is the error I am getting'role' table saved successfully'users' table- Unable to create relationship 'FK_users_role'.

hello all, I am new to SQL server and dont have a clue on how to create a one-to-one relationship in sql server2000. Say, I have a table 'A' with a PK <customer_id> and another table 'B' with a PK <order_id>. Now to define a one-to-one relation between them how to do that? thanks in advance.
What is the best way to relate the name in dbo.server and name in dbo.ProcessorInfo so this is a one to many? Obviously I can't set the name column as a PK as I have more than 1 record of the same value in it.
How do I create a relationship between two tables when the two columns that should connect each table have different names?
i.e. Table Person Column Name < -- > Table Employee Column Person Name
The two columns actually contain the same data type but different field name and size. I know this involves a series of steps. What are they? Could you please include some sample code.
Hi, I come back again. Can anyone help me to create table with many-to-many relationship. Here is my three tables tbl_Networks ( NID int identity(1,1) primary key, NetworkName nvarchar(256) )
tbl_Categories ( CID int identity(1,1) primary key, CateName nvarchar(256), NID int )
tbl_Sim ( SID int identity(1,1) primary key, NID int, CID int, NameOfSim nvarchar(256) ) My problem is 1 value in tbl_Sim may have multiple values in table tbl_Categories and vice versal. And I don't know how to organise them
Hi. I get this error when i try to create a relationship in a db diagram (sql 2005) "'tblActivedir' table saved successfully 'tblClient' table - Unable to create relationship 'FK_tblClient_tblActivedir1'. Introducing FOREIGN KEY constraint 'FK_tblClient_tblActivedir1' on table 'tblClient' may cause cycles or multiple cascade paths. Specify ON DELETE NO ACTION or ON UPDATE NO ACTION, or modify other FOREIGN KEY constraints. Could not create constraint. See previous errors."
What i have is 2 tables. 1 named client 1 named activedir
In the client table the columns i want to bind with activedirtable are FR1 and DC1 I want to bind them in the ID of the activedir table (both, in different fk relationships) so that they get the id of activedir. Fr1 has an fk relationship with activedir (pk is activedir' id) and DC1 exactly the same in another fk. So i want both columns to comunicate with activedir. If p.e. activedir has 3 elements (a,b,c) when i delete element a then werever FR1 or DC1 have this element(binded to it's id) then the element will also be deleted (id of the element) from both FR1 and DC1 I don't want to set Delete and Update action to none because i want the element changed or deleted from activedir, to do the same on Fr1 or DC1 or both. Any help? Thanks.
Hi, I have metadata that stored my table structure and relationship. I would like to know is it possible to create table relationship programatically? Any sample?
NozzleTbl is another Table.At the moment I am referencing only one NozzleTbl thrice. But how can I reference a collection of NozzleTbl thrice?So that in the c# code I could access the collections 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 a problem related to create or show relationship digram in sql server 2005. Especially, I want to show relationship diagram that I established in sqlserver 2000 in sql server 2005 but I can't and I don't how to do it.
I am fairly new to SQL and I am currently trying to createa SQL table (using Microsoft SQL) that has a recursiverelationship, let me try to explain:I have a piece of Data let's call it "Item" wich may again contain onemore "Items". Now how would I design a set of SQL Tables that arecapable of storing this information?I tried the following two approaches:1.) create a Table "Item" with Column "ItemID" as primary key, somecolums for the Data an Item can store and a Column "ParentItemID". Iset a foreign key for ParentItemID wich links to the primarykey"ItemID" of the same table.2.) create separate Table "Item_ParentItem" that storesItemID-ParentItemID-pairs. Each column has a foreign key linked toprimary key of the "Item" Column "ItemID".In both approaches when I try to delete an Item I get an Exceptionsaying that the DELETE command could not be executed because itviolates a COLUMN REFERENCE constraint. The goal behind these FK_PKrelations is is that when an Item gets deleted, all childItems shouldautomatically be deleted recursively.How is this "standard-problem" usually solved in sql? Or do I inned toimplement the recursive deletion myself using storedprocedures or something ?
I am bring two fact tables and a Date Dim into my Power Pivot model. I try to create relationship where but Power Pivot just reverses them. When I create the relationship I get an info icon warning me it will be changed.Why can't I create a one to many relationship with fact table on many side and dimension on one side?Power Pivot will not let me mark my dimCalnder as a date table either. My date dim has surrogate key, year, month and monthlongname columns only...Â
i have a table where the feilds are 1.fromtable 2.fromfeild 3.fromcategory 4.totable 5.tofeild 6.tocategory. i have write a stored proceduer for creating 2 relationship between fromfeild & tofeild from the same value in from category & in tocategory. there r around 465 records in a table. so anyone can comeout for solution of this. hope soon i get a solution for this.
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 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.
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.
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:

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),

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?
I 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)
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.
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.
I have a table that has a number of data fields,I need to be able to capture datatime when the date field was entered or entered value changed.I was told I need to create a trigger on that table that contains all the fields.
I have seen the syntax for creating triggers, and read some documentation but I am still in the dark as how to create what I need to.
I was hoping to see if somebody had a similar example or an advice, anything is more than what I have at the moment.
CREATE TRIGGER NotifyDateFieldUpdates ON RelocateeRemovalist For INSERT, UPDATE, DELETE AS DECLARE @RemovalistNumber VARCHAR(200) DECLARE @RelocateID INT
/*InspectionDate */ DECLARE getInsp CURSOR FOR SELECT RelocateID,RemovalistNumber FROM INSERTED a LEFT JOIN DELETED b ON (a.RemovalistNumber=b.RemovalistNumber and a.RelocateID=b.RelocateID) WHERE a.InspectionDate IS NOT NULL AND b.InspectionDate IS NULL
OPEN getInsp
FETCH NEXT FROM getInsp INTO @RelocateID, @RemovalistNumber WHILE (@@FETCH_STATUS <> -1) BEGIN INSERT INTO RelocateeRemovalistFieldEntry(RElocateID, RemovalistID)SELECT RelocateID,RemovalistID FROM INSERTED a LEFT JOIN RelocateeRemovalistFieldEntry b ON (a.RelocateID=b.RelocateID AND a.RemovalistNumber=b.RemovalistNumber)WHERE b.RElocateID is null
UPDATE RelocateeRemovalistFieldEntry SET InspectionDateDateTime=GETDATE() WHERE RelocateID=@RelocateID aND RemovalistNumber=@RemovalistNumber
FETCH NEXT FROM getInsp INTO @RelocateID, @RemovalistNumber END
DEALLOCATE getInsp
GO
This is what I was able to come up with so far,but when i check the syntax it gives me an error "Ambiguous column name "RelocateID" and "Ambiguous column name "RemovalistNumber" I don't know what is it trying to tell me here and couldn't find much help.
Since we have given Null to ''Workphone'',''Cellphone '', ''Email ID''.when inserting the data into these table.if the particular columns are empty while inserting also the data will get populate into the table.And.I need is if these columns are ''Workphone'',''Cellphone'' , ''Email ID'' they cant insert the data into table.
Like it must trigger like ''Please enter atleast one of these ''Workphone'',''Cellphone'' , ''Email ID'' columns.
