Query To Only Display Information From One Table Where The Foreign Key Doesnt Exist In The Other Table.
Nov 28, 2006
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.

Hi,
I did some tsql a year or so ago, it wasnt much but it allows me to do most things i need to do in my job.
I have created a new database for bookings, each booking has all the relevant details and also the date that it will occur. im trying to create a script that will look for the 10 soonest dates that there is no booking for. at first i thought it would be easy, but now once i have got round to creating it i cant seem to think of a way to make it work!
TABLE: BOOKINGS
FIELD: DATE_BOOKED
has anybody advice on how i can do this?
many thanks,
Ben

I'm trying to create a local copy of a popular CRM database calledSalesforce.com. Many of the tables in the DB have FOREIGN KEYreferences that I want to preserve, but I've run into a chicken and eggproblem. Table "A" has a reference to table "B," and table "B" has areference to table "A." So I can't CREATE one until the other exists.Is there a way to disable these checks until I've created all theschema?Here's what I see (error first, then SQL that caused it):Server: Msg 1767, Level 16, State 1, Line 1Foreign key 'FK__UserRole__LastMo__48CFD27E' references invalid table'User'.Server: Msg 1750, Level 16, State 1, Line 1Could not create constraint. See previous errors.CREATE TABLE salesforce3.dbo."UserRole" ("Id" varchar(18) PRIMARY KEY ,"Name" varchar(40), "ParentRoleId" varchar(18) REFERENCES"UserRole"(Id), "RollupDescription" varchar(80),"OpportunityAccessForAccountOwner" varchar(40),"CaseAccessForAccountOwner" varchar(40), "LastModifiedDate" datetime,"LastModifiedById" varchar(18) REFERENCES "User"(Id), "SystemModstamp"datetime);CREATE TABLE salesforce3.dbo."User" ("Id" varchar(18) PRIMARY KEY ,"Username" varchar(80), "LastName" varchar(80), "FirstName"varchar(40), "CompanyName" varchar(80), "Division" varchar(80),"Department" varchar(80), "Title" varchar(80), "Street" text, "City"varchar(40), "State" varchar(20), "PostalCode" varchar(20), "Country"varchar(40), "Email" varchar(80), "Phone" varchar(40), "Fax"varchar(40), "MobilePhone" varchar(40), "Alias" varchar(8), "IsActive"bit, "TimeZoneSidKey" varchar(40), "UserRoleId" varchar(18) REFERENCES"UserRole"(Id), "LocaleSidKey" varchar(40), "ReceivesInfoEmails" bit,"ReceivesAdminInfoEmails" bit, "EmailEncodingKey" varchar(40),"ProfileId" varchar(18) REFERENCES "Profile"(Id), "LanguageLocaleKey"varchar(40), "EmployeeNumber" varchar(20), "WirelessEmail" varchar(80),"LastLoginDate" datetime, "CreatedDate" datetime, "CreatedById"varchar(18) REFERENCES "User"(Id), "LastModifiedDate" datetime,"LastModifiedById" varchar(18) REFERENCES "User"(Id), "SystemModstamp"datetime, "UserPermissionsMarketingUser" bit,"UserPermissionsOfflineUser" bit, "UserPermissionsWirelessUser" bit,"UserPermissionsSuperCssUser" bit, "UserPermissionsAvantgoUser" bit);

I've created a new table in ASPNETDB.mdf called 'customerInfo'. Most of the fields are, for the moment, data that exists in one of the existing ASPNET tables eg Membership_UserId (primary key), Membership_Email, Users_UserName etc.; the list goes on. I have put a new column 'amountspent' - just to test that I can do what I think I can do, however the table doesn't display any data. Am I OK in thinking that I can use the aspnet data in my own tables and reference through foreign keys to them. I've made sure that the procedure that I used to put the table into a gridview on the webpage is OK as I did the same thing to the membership table and that displays all of its data. Can someone either explain the steps I need to make this happen correctly or point me in the direction of a noob type walkthrough.
Thanks

I am using SQL Server 2005 and trying to create a linked server on Oracle 10. I used the commands below:
EXEC sp_addlinkedserver
@server = 'test1',
@srvproduct = 'Oracle',
@provider = 'MSDAORA',
@datasrc = 'testsource'
exec sp_addlinkedsrvlogin
@rmtsrvname = 'test1',
@useself = 'false',
@rmtuser='sp',
@rmtpassword='sp'
When I execute
select * from test1...COUNTRY
I get the error. "The OLE DB provider "MSDAORA" for linked server "...." does not contain the table "COUNTRY". The table either does not exist or the current user does not have permissions on that table."
The 'sp' user I am connecting is the owner of the table. What could be the problem ?
Thanks a lot.

I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual
(empno,
accrued_vacation,
accrued_sick_effective_date,
accrued_sick,
import_date)

I have a table with a column AttributeNumber and a column AttributeValue. The data is like this:
OrderNo. AttributeNumber AttributeValue
1.-Order_1 2001 A
2.-Order_1 2002 B
3.-Order_1 2003 C
4.-Order_2 2001 A
5.-Order_2 2002 B
6.-Order_2 2003 C
So the logic is as follows:
I need to display in my query the values are coming from Order_1, means AttributreValues coming from AttibuteNumbers: 2001,2002,2003...and Order_2 the same thing.
Not sure how to create my Select here since the values are in the same table

I have a new installation of SQL Server 2000 Dev Edition on a Win2K3 Standard Edition Server that I used for development. I just set this machine up in th last week and installed all Win2K3 patches and then installed SQL2K and SP3a. I have a single named instance. I just noticed today that I cannot view table data or use the Query part of EM. When I right click a table and select Open Table->Return All Rows it gives me an error dialog "An unexpected error happened during this operation". While the EM is diplaying this dialog the EM screen looks like Internet Explorer and says "Action Canceled - You might not have permission to view this directory or page using the credentials you supplied." I believe that this is a EM issue as I cannot view table content on other remote server. ANy ideas? Might this be an IE security patch disallowing some connectivity ?--Frank--Message posted via http://www.sqlmonster.com

Hi,
I'm having a few problems. It's probably a simple thing but I can't figure it out.
I need to add data to a table but only if it isn't already in the table.
This is my query so far...
sqlcmd.CommandText = "Insert into caseDetails (c#,fe,cl) Values(@a,@b,@c)"
I assumed that if I added
WHERE not exists (case# = @a)
It would work and insert when the c# doesn't equal @a but all I get are errors.
Can anyone help?
Thanks,
Steve

I have table 'stores' that has 3 columns (storeid, article, doc), I have a second table 'allstores' that has 3 columns(storeid(always 'ALL'), article, doc). The stores table's storeid column will have a stores id, then will have multiple articles, and docs. The 'allstores' table will have 'all' in the store for every article and doc combination. This table is like the master lookup table for all possible article and doc combinations. The 'stores' table will have the actual article and doc per storeid.
What I am wanting to pull is all article, doc combinations that exist in the 'allstores' table, but do not exist in the 'stores' table, per storeid. So if the article/doc combination exists in the 'allstores' table and in the 'stores' table for storeid of 50 does not use that combination, but store 51 does, I want the output of storeid 50, and what combination does not exist for that storeid. I will try this example:
'allstores' 'Stores'
storeid doc article storeid doc article
ALL 0010 001 101 0010 001
ALL 0010 002 101 0010 002
ALL 0011 001 102 0011 002
ALL 0011 002
So I want the query to pull the one from 'allstores' that does not exist in 'stores' which in this case would the 3rd record "ALL 0011 001".

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?

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.

I am trying to pull a min value of a date column from table 1, if table 1 does not have any record I need pull a date column from table 2. Table 2 will always have a unique record ID (No duplicate ID's).
Table 1
ID date
1 1/1/2014
1 1/5/2014
Table 2
ID date
1 1/5/2014
2 10/15/2014
Here is the desired result when running for ID = 1 (select Min(date) where ID = 1, I should be getting 1/1/2014 from Table 1.
If I am running the same query where ID=2 then I should be getting 10/15/2014 from Table 2. So basically I need to check if a value exists on Table 1 first, if there is no value on Table 1 and then to grab the value from Table 2.

I need a SSIS Package that compares the two tables and removes the rows in the first table with keys that do not exist in the second table. For example....
I have a table of returns based on returnID. In another table I have returnErrors that are based on returnID as well. I want a package that will uses my returns table as a source and compares that dataset to the dataset of the returnError and remove or spilt the data so that my remaining dataset only has returns that have returnErrors. I can do this in T-SQL, but I am looking for a SSIS solution that uses the conditional split transformation or some other transformation(s) combinations.

I have been looking for a solution for this for some time and have came up empty handed.
I have 2 servers development box and a live box. Time has passed and my live box has a lot of new data in the database and now I need to update the dev box so I can properly test with real data. Problem here is I want to keep the records that are in the dev box, update them if they exsist on the live box, because live server may or may not contain that record and isert all records that are not on the dev box database.
I hope I am making some sense here, I think I am just making it more difficult then it has to be.
Any suggestions?

I got one table with 3 columns = Column1, Column2, Column3
Sample Table
Column1 | Column2 | Column3
------------------------------------
A | 12 | 0
A | 13 | 2
B | 12 | 5
C | 5 | 0
Select Column1, Column2, Column3 as New1
Where Column1 = A AND Column2 = 12 AND Column3 = 0
Select Column1, Column2, Column3 as New2
Where Column1 = A AND Column2 = 12 AND Column3 >0
The only difference is one condition Column3 = 0 and another one Column3 > 0. This two condition is not an "AND" condition... but just two separate information need to be display in one table.
So how do i display the result in one table where the new Output will be in this manner
Column1 | Column2 | New1 | New2|
Thanks

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,

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 have 2 identical tables one contains current settings, the other contains all historical settings.I could create a union view to display the current values from table A and all historical values from table B, butthat would also require a Variable to hold the tblid for both select statements.
Q. Can this be done with one joined or conditional select statement?
DECLARE @tblid int = 501
SELECT 1,2,3,4,'CurrentSetting'
FROM TableA ta
WHERE tblid = @tblid
UNION
SELECT 1,2,3,4,'PreviosSetting'
FROM Tableb tb
WHERE tblid = @tblid

Hi All,
It seems I have been requested to carry out a complex query and the best way I think I can do this is with the use of a stored procedure. The problem is that I am not quite sure whether my SP is stated correctly and also how I would go about stating the SP in my VB.net code!
I would be ever so grateful if somebody could look over my SP code and possibly recommend a way of stating my code. My ability is limited so I would appreciate it if examples could be used with possible relations to my problem.
The Problem?
Tables:
1.tblRisk: Ref(pk), subject, status(fk), staff(fk), Dept(fk)
2.tblDept: Ref(pk), Department
The SP should state that Department should appear as the end result of the query when the page is loaded. So when a row is selected in tblRisk, dependant upon what the Dept is in that table, it then populates the department in which it is associated with from tblDept. I have left the SP below.
Many Thanks,
Kunal
CREATE PROCEDURE dbo.ShowMe @yourInputValue INTAS SELECT tblDept.Department FROM tblDept JOIN tblRisk ON tblDept.Ref = tblRisk.Dept WHERE tblDept.Ref = @yourInputValue RETURN 0GO
