Transact SQL :: 2012 / Insert Foreign Key Value Into Primary Table?
Oct 2, 2015
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?

Is there anyway to get the order in which data to be import on to tables when they have primary and Foreign Key relations?
For ex:We have around 170 tables and when tries to insert data it will throw error stating table25 data should be inserted first when we insert data in table 25 it say 70 like that.
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?
CREATE TABLE StockNames ( -- Added Primary key to [stock_symbol] [stock_symbol] VARCHAR(5) NOT NULL CONSTRAINT PK_stock_symbol PRIMARY KEY, [stock_name] VARCHAR(150) NOT NULL, [stock_exchange] VARCHAR(50) NOT NULL,
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),

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?
I've following query which display the result as required, but I need to get the missing Primary Key Values which are not available in the result:
SELECTA.SignedByUserID, B.FullName, COUNT(A.OutletID) AS TotalSignups, DATENAME(Month, A.SignupDate) AS Month FROMdbo.tblMer_Outlet AS A LEFT OUTER JOIN dbo.tblGen_Users AS B ON A.SignedByUserID = B.UserID WHERE(A.SignupDate >= '2014-04-01 00:00:00' AND A.SignupDate <= '2014-04-30 23:59:59') GROUP BY A.SignedByUserID, B.FullName, DATENAME(Month, A.SignupDate)
This Query returns the following result:
SignedByUserID FullName TotalSignups Month -------------------------------------------------------- 9 Babu Raj 16 April 11 Faheem 19 April 39 Fasil Abbas 16 April 29 Hafiz Suleman 10 April
[code]....
which does not have a signup for the month of April, but I need it to be available for this or any upcoming month. I need this orr all users, which does not exists in the context needs to be displayed in the result.
Previously same records exists in table having primary key and table having foreign key . we have faced 7 records were lost from primary key table but same record exists in foreign key table.
I have question about the size of foreign key’s in sql-server 2012. If I in one table had a foreign key of the “INT” type. Do it still cost 4 bytes of storage?
I have come up with one scenarios where I have three table like Product, Services and Subscription. I have to create one table say Bundle where I can have some of the product id , service id and Subscription id , i.e. a bundle may contains sum prduct , services and subscription . How I can design these relations ?
An SSIS task imports data from a flat file and inserts the data into a staging table. The staging table holds the data in its raw form. A second process then selects the data from the staging table, looking up the foreign key id's for raw data values, and then inserts the data into the live table.
SQL - Only key columns shown for clarity -- Staging Table CREATE TABLE Staging (Information VARCHAR(10), MachineName VARCHAR(10), Status VARCHAR(10))
[code]...
The insert into the live table should look up the id for machine 1, and the id of status success and insert the foreign key values into the live table for the row.There could be 1000's of rows for the output of machine 1 all with different status's - (all pre set in the Status table, i.e success, failure, rerun) and the same for lots of other machines held in the machine table.
What is the best to insert this data all in one go, rather than reading each row of the staging table one by one, looking up the foreign key values depending on the machine and status values, then inserting the data.
I was thinking along the lines of:
INSERT INTO dbo.LiveTable (Information, MachineID, StatusId) SELECT Staging.Information, dbo.Machine.MachineId, dbo.Status.StatusId FROM dbo.Staging JOIN Machine ON Machine.MachineName = Staging.MachineName JOIN STATUS ON Status.Status = Staging.Status But I notice the problem with this is, it doubles up the inserts!
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?
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'.
Ok, I'm really new at this, but I am looking for a way to automatically insert new records into tables. I have one primary table with a primary key id that is automatically generated on insert and 3 other tables that have foreign keys pointing to the primary key. Is there a way to automatically create new records in the foreign tables that will have the new id? Would this be a job for a trigger, stored procedure? I admit I haven't studied up on those yet--I am learning things as I need them. Thanks.
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'
i'm using sql express, management studio express and a visual web developer starter kit. i have 4 tables: items; categories; categorization; old_items the old_items table has both the item id and category fields in it, the new db has them separated: items.id; categories.id; categorization.itemId, categorizaton.parentCategoryId, both of which are foreign keys. i need to get the old_item.id and old_item.category values into the new categorization table but it keeps choking on the foreign keys and i can't get past it. as far as i've been able to figure out so far, i need to turn off the foreign keys to do the insert but i'm not sure and i haven't been able to find any sql query examples that demonstrate it or explain it well enough for my n00b self. i've read http://msdn.microsoft.com/en-us/library/10cetyt6.aspx, "How to: Disable Foreign Key Constraints with INSERT and UPDATE Statements" but i don't get how that affects it, it seems like one of the other options would actually disable them. can anyone help? i've been trying all the permutations of queries i can think of and not getting it. thanks.
I've been working as web dev for quite sometime now but there are still few things that i would like to clarify. Hope you guys can shed lights.
I currently have several tables and all this tables are having some 1 to many relationships. I know that how i insert value into my tables are very inefficient. I do it in this manner.. -> Insert a value in TableA -> Query the latest ID that i have inserted in Table A then -> Insert this value in TableB. And so on and so forth.
I believe there is an efficient way to to do this but i'm not sure how? Could anyone shed me a light on this matter?
How to delete records from multiple tables if main table’s entity is deleted as constraints is applied on all..There is this main table called Organization or TblOrganization.and this organization have branches which are in Brach table called tblBranch and this branch have multiple applications let say tblApplication and these application are used by multiple users called tblUsers.What I want is: when I delete the Organization All branches, application and users related to it must be deleted also.How I can apply that on a button click in asp.net web forms..Right now this is my delete function which is very simple
Public void Delete(int? id){ var str=”DELETE FROM tblOrganization WHERE organizationId=”+ id ; } And My tables LOOK LIKE this CREATE TABLE tblOrganization ( OrganizationId int, OrganizationName varchar(255)
Both tblRoom and tblEquipment have the red line error which when I highlight say the they both reference an invalid table!
Both tables are there and have primary keys defined as ID & Type. I have searched around and all I could find was that there maybe a permission problem.
I have a table that is riddled with weird characters. So far I have found an escape character for PDF files and a trademark sign. These characters are crashing my SSIS packages. I am able to remove these characters with an update script...
Update TABLE set LEAD_NOTES__C = Replace(LEAD_NOTES__C, nchar(65533) COLLATE Latin1_General_BIN2, '!');
Update TABLE set LEAD_NOTES__C = Replace(LEAD_NOTES__C, nchar(1671) COLLATE Latin1_General_BIN2, '!');
This works fine, but my question is...
I would like to write a script that removes all foreign characters with the exception of the normal characters like (@,#,$,%,etc). I need a dynamic process that handles this so I am not losing time sifting through over 20,000 rows of data and changing my update script to remove a specific column. Although this method works, I would prefer a dynamic query. I intend to wrap this in a stored procedure that loops through all columns in a table (as parameter).
I'm going through my tables and rewriting them so that I can create relationship-based constraints and create foreign keys among my tables. I didn't have a problem with a few of the tables but I seem to have come across a slightly confusing hiccup.
Here's the query for my Classes table:
Code:
CREATE TABLE Classes ( class_id INT IDENTITY PRIMARY KEY NOT NULL,
This statement runs without problems and I Create the relationship with my Users table just fine, having renamed it to teacher_id. I have a 1:n relationship between users and tables AND an n:m relationship because a user can be a student or a teacher, the difference is one field, user_type, which denotes what type of user a person is. In any case, the relationship that's 1:n from users to classes is that of the teacher instructing the class. The problem exists when I run my query for the intermediary table between the class and the gradebook:
Code:
CREATE TABLE Classes_have_Grades ( class_id INT PRIMARY KEY NOT NULL,
Query Analyzer spits out: Quote: Originally Posted by Query Analyzer There are no primary or candidate keys in the referenced table 'Classes' that match the referencing column list in the foreign key 'Classes_have_gradesFKIndex2'. Now, I know in SQL Server 2000 you can only have one primary key. Does that mean I can have a multi-columned Primary key (which is in fact what I would like) or does that mean that just one field can be a primary key and that a table can have only the one primary key?
In addition, what is a "candidate" key? Will making the other fields "Candidate" keys solve my problem?
For some reason, I'm getting this error, even without the DBCC Check:
INSERT statement conflicted with COLUMN FOREIGN KEY SAME TABLE constraint 'Category_Category_FK1'. The conflict occurred in database 'mydb', table 'Category', column 'CategoryID'. The statement has been terminated.
The very first insert fails...it was working fine before:
/* Finally, insert the rest and match on the Parent Category Name based on the CategoryStaging table */
WHILE (@@ROWCOUNT <> 0) BEGIN INSERT INTO Category (ParentCategoryID, [Name], [Description], DisplayOrder, DisplayInExplorer, Keywords, Active, CreateDate, CreateUserID, UpdateDate, UpdateUserID) SELECT c.CategoryID, s.CategoryName, '', 1, 1, '', 1, GETDATE(), 1, GETDATE(), 1 FROM Category c INNER JOIN CategoriesStaging s ON c.[Name] = s.ParentCategoryName WHERE NOT EXISTS (SELECT 1 FROM Category c WHERE s.[CategoryName] = c.[Name]) AND s.CategoryName <> 'All'
Here's the schema:
CREATE TABLE [dbo].[Category]( [CategoryID] [int] IDENTITY(1,1) NOT NULL, [ParentCategoryID] [int] NULL, [Name] [nvarchar](255) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
CONSTRAINT [Category_PK] PRIMARY KEY CLUSTERED ( [CategoryID] ASC ) ON [PRIMARY] ) ON [PRIMARY]
GO USE [mydatabase] GO ALTER TABLE [dbo].[Category] WITH NOCHECK ADD CONSTRAINT [Category_Category_FK1] FOREIGN KEY([ParentCategoryID]) REFERENCES [dbo].[Category] ([CategoryID])
I have a table of raw data where each column can be null. The thought was to create an identity key (1,1) and set as primary for each row. (name/ address / zip/country/joindate/spending) with surrogate key: "pkid".However other queries will not use this primary key. So for instance they may count the # of folks at a zip, select all names, addresses etc. The queries may order by join date, or select all the people that joined on a specific date.No other code would logically use the primary key (surrogate primary id key), therefore would it still have any performance benefits? at this time the table would have no clustured or nonclustured indexes or keys. I'm curious if there are millions of records.
I would like to insert into a table with a primary key that has a uniqueidentifier. I would like it to go up by one each time I execute this insert statement. It would be used as my ReportId My VB code is this.
