I am seeing untrusted foreign key in one of my tables in a dev environment. To fix it I tried to run
ALTER TABLE [dbo].[TableName] WITH CHECK CHECK CONSTRAINT [ForeignKey]
But I am getting the below error
The ALTER TABLE statement conflicted with the FOREIGN KEY constraint "foreignkey". The conflict occurred in database " DBname", table "dbo.tablename", column 'columnname'.
I 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?
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 definitions:
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? Thus can you either modify the sql that I just listed above and/or come up with some new sql that will show me how to accomplish my goal?
I've attempted to identify a primary and foreign key in these two tables, but I am getting a bunch of errors re duplicate keys and column names needing to be unique.Perhaps the primary and foreign key I have identified don't meet the criteria?

I am still new to SQL and I am having trouble obtaining the results I need from a query. I have worked on this command for some time and searched the internet but cannot seem to still get it correct.
I have a table called Patient. It's primary key is pat_id.
I have a second table called Coverage. It has no primary key. The foreign keys are pat_id, coverage_plan_id, and hosp_status.
I have a third table called Coverage_History. It has a primary key consisting of pat_id, hosp_status, copay_priority, and effective_from.
I want to get the pat_id and all the coverage information that is current. The coverage table contains specific insurance policy information. The coverage_history table will indicate the effective dates for the coverage. So the tables could contain something like this:
Patient (pat_id and lname)
P123 Monto
P124 Minto
P125 Dento
P126 Donto
Coverage (pat_id, coverage_plan_id, hosp_status, policy_num)
P123 MED1 OP A1499
P123 ACT4 OP H39B
P124 MED1 OP C90009
P124 RAC OP 99KKKK
P124 RAC OP 99KKKK
P124 MED1 OP C90009
P125 ARP OP G190
P126 BCB OP H88
Coverage_History (pat_id, hosp_status, copay_priority, effective_from, coverage_plan_id, effective_to)
P123 OP 1 20150102 MED1 NULL
P123 OP 2 20150102 ACT4 NULL
P124 OP 1 20150203 RAC 20150430
P124 OP 2 20150203 MED1 20150430
P124 OP 1 20150501 MED1 NULL
P124 OP 2 20150501 RAC NULL
P125 OP 1 20150801 ARP NULL
P126 OP 1 20150801 BCB 20160101
select p.pat_id, p.lname, ch.coverage_plan_id, ch.hosp_status, ch.effective_from, ch.effective_to, ch.copay_priority,
from patient p
left join
( coverage_history ch left join coverage c on ch.coverage_plan_id = c.coverage_plan_id and ch.patient_id = c.patient_id and
(ch.effective_to is NULL or ch.effective_to >= getdate()
)
) on ch.patient_id = p.patient_id
where ( ch.effective_to is NULL or ch.effective_to >= getdate() )
So I want to see:
P123 Monto MED1 OP 20150102 NULL 1
P123 Monto ACT4 OP 20150102 NULL 2
P124 Minto MED1 OP 20150501 NULL 1
P124 Minto RAC OP 20150501 NULL 2
P125 Dento ARP OP 20150801 NULL 1
P126 Donto BCB OP 20150801 20160101 1
I have an issue where i am mandated to enforce RI on an applications database (a good thing). but I have several common lookup tables where many of the "codes" reside for many different code types. I also have the mandate that i cannot change the underlying DDL to make composite keys to match the codes table PK. I am currently looking at creating indexed views on top of the Codes table to seperate the logical tables it contains. This is several hundred views.
I do know that I do not want to write several hundred triggers to enforce RI. Table schema below, the CdValue column is the column that is used throughout the hundreds of tables that use this codes table, and their corresponding column is not named the same.
CREATE TABLE dbo.CodesTable (
PartyGrpId INT NOT NULL
, CdTyp VARCHAR ( 8 ) NOT NULL
, CompId INT NOT NULL
, CdValue VARCHAR ( 8 ) NOT NULL
, CdValueDesc VARCHAR ( 255 ) NULL
, AltValueDesc VARCHAR ( 100 ) NULL
[Code] ....
I did though run into one forum where a person brought up a great idea. Filtered Foreign Keys, what a novel concept, if it could work it would make so much less code to fix an issue like this.
ALTER TABLE dbo.BusinessStatus WITH NOCHECK
ADD CONSTRAINT FK_dbo_BusinessStatus_CodesTable FOREIGN KEY (LoanStsDtCd) REFERENCES dbo.CodesTable (CdValue) WHERE CdTyp = 'Status'

suppose if we do not have FK then what kind of advantage we could not avail. we can fetch data from two table by creating a relation in sql.....then why FK is required.

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.

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

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?
View 1 Replies View RelatedHi,
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,

How do I create a table with a foreign key
View 6 Replies View RelatedHi,
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.

I'm using SQL Server 2000. I have an EXTERNAL_FUNDING table and an EXTERNAL_FUNDING_TYPE table. The DDL for the tables is listed below. Each EXTERNAL_FUNDING record has a type field, which is a foreign key to a record in the EXTERNAL_FUNDING_TYPE table. However, I would like for the type to be allowed to be null. When displaying the data, if the type is null, I'd like to show blank text. Here is the query I'm trying to use:
SELECT EXTERNAL_FUNDING.id, date_requested as [Request Date],source as [Source/Sponsor],EXTERNAL_FUNDING_TYPE.type AS [Type],amount as [Amount], granted as [Granted]
FROM EXTERNAL_FUNDING,EXTERNAL_FUNDING_TYPE
WHERE (project_id = @project_id) AND
(EXTERNAL_FUNDING.type = EXTERNAL_FUNDING_TYPE.id)
ORDER BY date_requested ,source,type
But this query does not return the records with NULL for the type field. Can someone explain to me how I can also return the rows with a NULL type? Thanks!
