Hi
I am creating new SQL Server Tables using SQL Server 2005. I have set
primary key to the tables .But I do not know how to assign Foreign key
to the tables .I need to do some joins later and that is why I have to
put Foreign key to the table . The Primary key is visible and can be
assigned easily .But How do I assign foreign key .
Thanks

We're having a few linked servers in our company. some tables in one of the linked servers include columns (better saying, foreign keys) of tables in another server. I wonder if there's a way to create a foreign key referencing one column in another server. That is, suppose there's Column A in table A in Server A which references Column B in table B in server B, is there a way to create column A as foreign key referencing column B?
Any idea is appreciated.

Hi I'm new to SQL and I'm trying to build a store procedure. What I'm trying to find out is how to assign a variable a value from a table.
So, I declare a variable:
DECLARE @variable int
Then I want to assign a single int value to that variable that is already in a table. For instance the id value from a single row in a table.
I've tried SELECT INTO and SET, but nothing has worked so far and I'm lost after searching for a few hours.
Thanks in advance for any help
In a special request run, I need to update locker and lock tables in a sql server 2012 database, I have the following 2 table definitiions:
CREATE TABLE [dbo].[Locker](
[lockerID] [int] IDENTITY(1,1) NOT NULL,
[schoolID] [int] NOT NULL,
[number] [varchar](10) NOT NULL,
[lockID] [int] NULL
CONSTRAINT [PK_Locker] PRIMARY KEY NONCLUSTERED
[code]....
The locker table is the main table and the lock table is the secondary table. I need to add 500 new locker numbers that the user has given to me to place in the locker table and is uniquely defined by LockerID. I also need to add 500 new rows to the corresponding lock table that is uniquely defined in the lock table and identified by the lockid.
Since lockid is a key value in the lock table and is uniquely defined in the locker table, I would like to know how to update the lock table with the 500 new rows. I would then like to take value of lockid (from lock table for the 500 new rows that were created) and uniquely place those 500 lockids uniquely into the 500 rows that were created for the lock table.
I have sql that looks like the following so far:
declare @SchoolID int = 999
insert into test.dbo.Locker ( [schoolID], [number])
select distinct LKR.schoolID, A.lockerNumber
FROM [InputTable] A
JOIN test.dbo.School SCH ON A.schoolnumber = SCH.type and A.schoolnumber = @SchoolNumber
JOIN test.dbo.Locker LKR ON SCH.schoolID = LKR.schoolID
AND A.lockerNumber not in (select number from test.dbo.Locker where schoolID = @SchoolID)
order by LKR.schoolID, A.lockerNumber
I am not certain how to complete the rest of the task of placing lockerid uniquely into lock and locker tables?
I have variables and values stored in a table in this format

how to assign values to variables in SSIS?
basically i'm looking for SQL equivalent of the following query i currently use to assign values to multiple variables (in a single query)
SELECT
@varRemoteLogServer=MAX(CASE WHEN [t_variable] = 'Remote_Log_Server' THEN [t_value] END)
,@varVariable2=MAX(CASE WHEN [t_variable] = 'variable2_name' THEN [t_value] END)
FROM Ref_Table
WHERE process_id=1
I'm working on creating a new version of an existing table. I want to keep the old table around, only with a different name. In looking this up I found there's a system routine named sp_rename, which looks like it will work fine.However in thinking about this I realized that the foreign key constraints defined on the table (there's 3 of them) are likely to not be renamed, correct?
If I'm correct, then I suppose I could rename the table, then drop the 3 foreign key constraints, and create them new using different names for those foreign key constraints.
How to copy a table from one server to another server with primary and foreign key constraints.
View 5 Replies View RelatedHi
We used to used Sql Server 2000 DTS to perform daily backups to remote servers very successfully but just cannot do the same with SSIS.
I set my Transfer Sql Transfer Objects Task to use the following settings:
CopyData = true
ObjectsTocopy = All Tables
As soon as it hits a table that has a foreign key, I get the following error:
"Truncate data failed for Table nnn"
I've tried setting DropObjectsFirst = True but this fails too with foreign key violations.
First of all, am I doing something obviously wrong? Is SSIS not smart enough to drop tables in the right order so that we don't get foreign key violations?
Am I totally barking up the wrong tree with this and can anyone suggest a better way of doing remote backups?
Kind regards
Ben
I want to make a query, stored procedure, or whatever which will only display the primary key where there does no exist a foreign key in linked table.For example. If I had two tables with a one to many relationship.A [Computer] has one or more [Hard Drives]. I want to select only those computers which do not have a Hard Drive(s) associated with them. That is, show all computers where the Computer_ID field in the [Hard Drives] table does not exist. This seems simple but I'm drawing a blank here.
View 1 Replies View RelatedI need to delete records from a table (Table1) which has a foreign key column in a related table (Table2).
Table1 columns are: table1Id; Name. Table2 columns include Table2.table1Id which is the foreign key to Table1.
What is the syntax to delete records from Table1 using Table1.Name='some name' and remove any records in Table2 that have Table2.table1Id equal to Table1.table1Id?
Here is my issue I am new to 2005 sql server, and am trying to take my old data which is exported to a txt file and import it to tables in sql. The older database is non relational, and I had made several exports for the way I want to build my tables. I built my packages fine and everything is working until I start building relationships. I remove my foreign key and the table with the primary key will get updated for the package again. I need to update the data daily into sql, and once in it will only be update from the package until the database is moved over.
It will run and update with a primary key until I add a foreign key to another database.
Here is my error when running the package when table 2 has a foreign key.
[Execute SQL Task] Error: Executing the query "TRUNCATE TABLE [consumer].[dbo].[Client] " failed with the following error: "Cannot truncate table 'consumer.dbo.Client' because it is being referenced by a FOREIGN KEY constraint.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
Hello all, I'm creating a stored procedure in SQL Server 2000. I'm trying to count how many rows match a certain WHERE clause, and assigning this integer to a variable:
----------------
DECLARE @RowCount int,
SELECT COUNT(*) FROM Customers WHERE FirstName='Joe'
----------------
How can I assign the count that returns from the SELECT statement to the @RowCount?
Thanks

I have a table named tblqualificationmaster.
can i know the foreignkeys and the table related to this
tblqualificationmaster having foeign keys using stored procedure."
Given a Table1 with two columns 'Name' with some N rows of data and another Table2 with one column 'SeqNo' with N rows, each of which contains a unique integer which can be ordered monotonically, I want to do an INSERT into some Table3 with two columns 'Name' and 'SeqNo' such that each INSERT'd row gets one of the unique integers.
E.g. -
Table1 contains 'Fred','Tom','Mary','Larry'
Table2 contains 6000978,6000979,6000980,6000981
INSERT INTO Table3
SELECT Table1.Name
Table2.SeqNo
FROM Table1
And I want to get Table3
'Fred',6000978
'Tom'.6000979
'Mary',6000980
'Larry',6000981
How can I reference Table2 so that Table2.SeqNo will 'line up' properly? Note that the ordering of the SeqNo values isn't mandatory as long as each SeqNo is assigned to one and only one row.
On edit: Table2 isn't required, it's just the way I started thinking about it. It would be nicer to just have two integer vars, @StartSeqNo = 6000978 and @EndSeqNo = 6000981 for he example above. Either way is fine.
I have a data set that looks something like like this:
Row# Data
1 A
2 B
3 B
4 A
5 B
6 B
7 A
8 A
9 A
I need wanting to assign a group ID to the data based on consecutive values. Here's what I need my data to look like:
Row# Data GroupID
1 A 1
2 B 2
3 B 2
4 A 3
5 B 4
6 B 4
7 A 5
8 A 5
9 A 5
You'll notice that there are only two values in DATA but whenever there is a flip between them, the GroupID increments.
Dear All:
I am new to SSRS 2005.
I have created many shared datsources and reprots at http://localhost/resportserver.
I am trying to access these reports from ReportViewer in the web application. Actually I want to use these reports for different customers by just changing the datsource programitically.
Is this is a possible?
Thank you

it is attributed ?
Hi everyone,
My table contains columns that are goreign keys to other tables. How can i tell to which table/column each fk is attributed ?
Thanks
For this example suppose than we a have a DB in SQL Server 2000 with the tables Client, Orders and DetailOrders. the field for each one are:
Client: id_Cliente, Name_client
Orders: id_Order, fk_client, date
DetailOrders: id_Detail, fk_Order, Product
Between all this tables exist one or more foreign key restriction but I don't know them. However I know than exist a row in the SYSOBJECTS (system table) per each one of the foreing key restriction, using this information I want to build a query than back to me something like this:
Type Table1 Field1 Table2 Field2
--------------------------------------------------------------------------------------------------------
FK Orders fk_Client Clients id_Client
FK DetailOrders fk_Order Orders id_OrderFK
Somebody can tell me hoy can i do it?

How do I write a query using the split function for the following requirement.I have a table in the following way
Identity Name Col1 Col2 Col3
1 Test1 1,2,3 200,300,400 3,4,6
2 Test2 3,4,5 300,455,600 2,3,8
I want an output in the following format
Identity Name Col1 Col2 Col3
1 Test1 1 200 3
1 Test1 2 300 4
1 Test1 3 400 6
2 Test2 3 300 2
2 Test2 4 455 3
2 Test2 5 600 8
If you see the data, first element in col1 is matched to first element in col2 and 3 after splitting the string.
The following works in query if I specify one student (PlanDetailUID) when running query. If I try to specify multiple students (PlanDetailUID) when running query, I get variable cannot take multiple entries. I assume I would need to replace (variables) in PART 2 with (case statements / using select everywhere) to get around the issue or is there a better way ?

I was thinking of adding tables to ASPNetDB.mdf and have one of those tables have column userid as a foreign key from aspnet_Users
When I try to create relationship in Diagram, I get error saying that "data typ properties does not match"

What should I use, should I do that at all?

I have created two tables in phpMyAdmin 3.5.8.1. comments which stores comments users post on a website and registration which stores a users registration details (username, password, e-mail etc, etc).
I want to add the username field from the registration table as a foreign key to the comments table. How do I do this in phpMyAdmin?
use default pubs database in sqlserver2000.
use authors table and publishers table.
Write a query to list first name, last of all authors
and name of the publisher (if any) present in the same city
as the author. If no publisher is present in the city
where the author is located then the column should contain a
NULL value. If there is more than one publisher in the city
where the author is located, then the details of
the author are to be repeated for each publisher.
but there is no field match between authors table and publishers table.
There is itemlookup table, which stores item number and itemdescription. Also there is a child table, pricehistory, of theitemlookup table, which stores different prices and different dateranges. So it is one-to-many relationship. (Price can be stored morethan one with a different date range)And there is another table RequestItem that stores the foreign key ofthe itemlookup table to show the information of the itemlookup table.Then how do I know later which date range of the price was stored inthe RequestItem table? Since I only keep the foreign key of theitemlookup table, it will be impossible to keep track of the row of thepricehistory table if there are more than one data existed in thepricehistory table.Will it be a valid table structure to create a column for the foreignkey of the pricehistory in RequestItem table or any other ways tohandle this issue?

I have a datatable with the following values:
ID
CompanyID
CompanyName.
Here ID is the foreign key. I was wondering if there was a way to update tables with foreign keys. Searching for stuff gave me something like update cascade. Can somebody please elaborate on that?
I've just found out about the concept that a table should only be references by foreign keys a maximum of 253 times throughout the database. I was hoping someone could give me a better idea of the dangers of disregarding this recommendation.
In our database, we have a Users table, which contains all of the users of a given system. In nearly every other table in our database, we have a field to indicate which user created the record. This is a reference back to the Users table. But as the number of tables has grown, we've surpassed that 253 limit. All I can tell, practically, is that I can no longer delete from the Users table. The query will fail, telling me the query optimizer ran out of memory, and that I should simplify my query.
The Users table is the only table that even comes close to this number of foreign key references. I don't even mind being unable to delete from the table. I'm mostly wondering if there are other problems with my design that will cause issues?
Is there a better way to keep track of who created a record in the database? Is it bad design to reference my Users table in so many places?
Thanks,
Newbie question. Can someone show me an SQL statement that sorts the results of a query by a field in a different table?
CREATE TABLE `Table1`
(
`table1_id` INTEGER AUTO_INCREMENT ,
`table1_name` VARCHAR(255),
PRIMARY KEY (`table1_id`)
)
CREATE TABLE `Table2`
(
`table2_id` INTEGER AUTO_INCREMENT ,
`table2_name` VARCHAR(255),
`table2_table1` INTEGER,
PRIMARY KEY (`table2_id`)
)
ALTER TABLE `Table2` ADD FOREIGN KEY (`table2_table1`) REFERENCES `Table1`(`table1_id`);
What I'd like is something like:
SELECT * FROM Table2 ORDER BY "Table1(table2_table1).tabel1_name",table2_name
It's the section in double quotes that I can't figure out how to compose.
As an example, if Table 1 has
1, A
2, B
3, C
and Table 2 has
1, a, 2
2, b, 1
3, c, 2
then I'd like the sort to return
2, b, 1
1, a, 2
3, c, 2
TIA,
Stephen
I have two tables as below. I want to update a quote and change the item for which it is for. So I want to do an update statement to change the cat_ref that the quote is for. However, when I do this I get a foreign key conflict with cat_ref in the item table. How do I get around this? Thanks
Code:
CREATE TABLE Item (
cat_ref VARCHAR(5)PRIMARY KEY,
descrip VARCHAR(50),
date_added SMALLDATETIME,
cat_type VARCHAR(20))
CREATE TABLE has_quote (
quote_id INT IDENTITY (1,1) PRIMARY KEY,
date_last_pricecheck SMALLDATETIME,
cat_ref VARCHAR(5)FOREIGN KEY
REFERENCES Item(cat_ref)
ON DELETE CASCADE,
first_name VARCHAR(10),
surname VARCHAR(10),
FOREIGN KEY (first_name, surname)
REFERENCES Customer(first_name, surname)
ON DELETE CASCADE
ON UPDATE CASCADE)
