Linking ID From One Table To Data In Another Table?
Mar 15, 2012
I have an assignment where I am to create two tables within a database. One of the tables have the name ContactPerson with the attributes; ID, Forename, Surname, Email, PhoneNumber. The other table is called Company and has the attributes: ID, CompanyName.
Now my problem is that I have to link a ContactPerson to a specific company, but I can't have them in the same table.
I understand that I can use the join statement to show both tables in one query but I need the database to know which person is linked to which company when I implement this databse into my asp.net project.
i have 6 table in SQL Server and i have created one view and create single table by linking all the table,now i want to join two column like
Column A and Column B = Column C e.g A B C Atul Jadhav Atuljadhav Vijay vijayvijay
in above exambe column A having firstName and Column B having second name and i want to join this two column in C column "atuljadhav" and if column B is blank then it join A value tow timestriger code as it is auto update column and every time (update, append, modify, delete) it should be update automatic
I have several pdf files that need to be imported into the database. Each pdf file is to link to several rows in a database. The files have different file names and keep coming every week. I need to import them into a table and link it with the data table. Need help on how to get the filename out of the pdf file and save it on the table with the image. I can use that filename as the foriegn key..Any help would be really great.. -Sri
Little puzzle this.I need to link from SQL2000 to Access to get to a table held within anAccess DB. Now you can link within Access to a SQL table, but can thisbe done the other way round ? It's the first time I've needed to dosomething like this.What I have is an application which was written (by me) with an Accessbackend (to run on a CD) and now it needs to run on SQL. However, Iwant to be able to swap over between backends so that I can choosewhere this runs from. I've done this with the sole exception of onetable. Previously most of the data was held in one MDB file and a linkto another (one local copy and one on CD). My queries use the link toquery both local and the CD copy data together.I can re-write things if I need to, but I was curious about there beinga way of doing this. What I want in effect is to query a view on SQL,but the data will be held in Access instead of on SQL.I suppose I can import as I need it as the data is purely read only. Idon't think this can be done, but wanted to check first. I can alwaysmove the remainder of the data over to SQL if needed. It's not a bigproblem, just something I'm curious about.Any pointers would be appreciated.Thanks in advanceRyanp.s. In case anyone wonders why I have taken this approach it isbecause we have a query tool and data that we send out to clients onCD. Some now want this web based, so I will publish the application ona Citrix server, and by changing a config file can swap within theapplication to point to SQL (by changing the ODBC settings). This way,I only need one copy of the application and can change backends as Ineed to.
Can someone help me with how I should set the relationship in my address tables and how they will affect the deleting of a client? So, if I have: tblClients ClientID tblClientAddresses AddressID tblClientAddressLinks AddressID, ClientID Currently I have them set as a 1-M from tblClients to tblClientAddressLinks and a 1-M from tblClientAddresses to tblClientAddressLinks If I try and delete a client and there address is shared wont this go very wrong? So here is what happens when I try and delete a client: The DELETE statement conflicted with the REFERENCE constraint "FK_tblClientAddressLinks_tblClients". The conflict occurred in database "DBSQL2", table "dbo.tblcLIENTAddressLinks", column 'clientID'.The statement has been terminated. Here is what happens when I try and delete an address: The DELETE statement conflicted with the REFERENCE constraint "FK_tblClientAddressLinks_tblClientAddresses". The conflict occurred in database "DBSQL2", table "dbo.tblClientAddressLinks", column 'Address_ID'.The statement has been terminated.
I am trying to link a table from a MS SQL database into access97 thru ODBC. When I do this, I get the message "Can't define field more than once." When I look at the table in SQL, there are no duplicate field names, however, when I bring the table in to do a Crystal Report, I see there are 2 fields that have duplicate field names 6 times. (Evidently Crystal doesn't care about this as Access does.) Any clues on what is happening?
I would like to hear your thoughts on a philosophy I adhere to.
As a rule of thumb I've always preached that Unique Indexes are for linking tables and Primary Keys are used to ensure that records aren't duplicated. I’ve embraced this philosophy for a couple reasons, the main one being that I don’t have to create numerous foreign key fields in the foreign key table.
However I’ve done most of my programming in Access and am now in need of something more robust (SQL Server v7) and I’m wondering if I need to reconsider.
I do also have a how to question; that being is it possible to create a table join on a unique index in SQL Server v7 and if so how? I would like to have an Auto Number / Auto Incremented / Unique Identifier field in the Primary Key table that links to a numeric field in the Foreign Key table.
Rather than using the upsize wizard in MS Access to connect to tables on a backend SQL server, how would I go about linking an Access Database to an existing table on an SQL server?
I would like to create a MSAccess97 front end for some SQL7 data. I created an odbc source system dsn for the server holding the SQL7 data. When I try to add a table to my Access97 database by linking it to a SQL7 table, the only choices presented me are tables in the default database for SQL7 on my server. How do I link to tables in another database on that server? Thanks.
I`m trying out SQLServer7, have installed it on my workstation, have been able to open access97 and link to sql7 tables I created. Want another user to use access97 to set up her own database and link to my sql7 tables. Do I need to install anything from the sql7 beta disk on her desktop? Right now she can`t link a sql7 table to her access97 db. Thanks.
I'm having problems seeing the correct data type when linking my Access tables to MS SQL Server 2005. My varchar(max) fields are showing as text(255). I'm using the SQL Native Client.Has anyone else ssen this issue?
Something strange has happened to my table. I used Enterprise Manager today to delete 3 columns. When I went to re-link the table using Access Linked Table Manager, it gave me an error. I then deleted the link to the table, and tried to Link it again using 'Get External Data---Link Tables'. I am getting an error (no surprise!):
" 'dbo.tblSpaceUse.PK_RoomID' is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long".
When I go into Enterprise Manager to 'manage Indexes' on the table, it shows me that the existing index is in fact dbo.tblSpaceUse.PK_RoomID.
About a month ago, I had to rename the index, because it had been pointing to the wrong table. The SQL I used to rename it (in Query Analyzer) is: EXEC sp_rename 'dbo.tblSpaceUse.PK_RoomID', 'tblSpaceUse.PK_RoomID', 'INDEX'
I have been using the table successfully since then, until today. I have not done anything with the index; the only change I attempted was to delete 3 columns (not related to the index). I do not think I have made any changes to the table since I renamed the index.
I tried to run the rename SQL again (a desperate attempt!) and get the error message: Server: Msg 15248, Level 11, State 1, Procedure sp_rename, Line 192 Either the parameter @objname is ambiguous or the claimed @objtype (INDEX) is wrong.
Any ideas on what went wrong and what I can do to fix it???
I am using SQL 2008 r2. I have two SQL Queries from 2 different database but they share one server. I need to linked these two SQL Queries as they share the same Primary key which CustomerID see example below
Query 1
Database::Student Select StudentID , FName, LName From Student
Query 2
Database ::Finance Select StudentID,Tution FROM Payment
I need to be able combine two query which come from two database but they share one server.I would like to use two temp tables so that I can perform a left / right join to retrieve the data by linking two queries using primary id which they both share ( StudentID)
Summary : I have two DB's on the same server. I have two simple select queries for each DB which work correctly.
I have a table 'Group2Operation' that stores many to many relationsbetween the 'Group' table and the 'Operation' table (each group is haspermission to perform one or more of the available operations)PROBLEM=======I need to prevent duplicate entries being created. e.g. lets say thatin the 'Group2Operation' table a record links the 'editor' group tothe 'publish' operation. Should I prevent an administrator creating aduplicate of that record? (Otherwise deleting that permission willhave to be done twice or more for it to be effective)SOLUTION?=========So far I've done this with a trigger:CREATE TRIGGER Group2OperationDuplicates ON dbo.Group2OperationFOR INSERT, UPDATEAS UPDATE Group2OperationSET NoDuplicate = CONVERT(nvarchar(10),GroupID) + OperationTagThe 'NoDuplicate' unique index column in the Group2Operation tablestores a concatenation of the unique group and operation identifiers.So when an attempt is made to create a record, the trigger is fired.If there is a duplicate, this will mean a duplicate entry in the'NoDuplicate' column. As a result, the INSERT or UPDATE will fail andthe duplication will be prevented.WHAT DO YOU THINK?==================What do you think? Am I going about this in the right way? Is atrigger a good way to do this or should I rely on application logic toprevent duplicates?Any help appreciated by this db novice.John Grist
Hi there, I just upsized my access database which has several tables and query linked to one of the tables residing on a seperate access database. When I do add in the diagram section, I see only table, then my question how would I be able to do the same thing under SQL Server 2005? thank you
I have transaction table where the rows entered into the transactioncan come a result of changes that take place if four different tables.So the situation is as follows:Transaction Table-TranId-Calc AmountTable 1 (the amount is inserted into the transaction table)- Tb1Id- Tb1AmtTable 2 (an amount is calculated based on the percentage and insertedinto the transaction table)-Tbl2Id-Tb2PercentageTable 3 (the amount is inserted into the transaction table)-Tbl3Id-Tbl3AmutTable 4 (an amount is calculated based on the percentage and insertedinto the transaction table. )-Tbl2Id-Tb2PercentageHow do I create referential integrity between the Transaction table andthe rest of the tables. When I make changes to the values in Table 1 -4, I need to be able to reflect this in the Transaction table.Thanks.
I am modelling two fact tables of Actuals and Budget which are at different granularity, Actuals are at day, customer and product sub category level. Budgets are at month, Region and Product category level.
Month, Region and Product Category is present in Date, Region and Product Category dimension respectively. I have only three dimensions as Customer, Product and Date. Linking those dimensions to Actual Fact table is not an issue, what is the best way and options are there to link budget fact table to those three dimensions.
Hi can anyone help me with the format of my stored procedure below. I have two tables (Publication and PublicationAuthors). PublicaitonAuthors is the linking table containing foreign keys PublicaitonID and AuthorID. Seeming as one Publication can have many authors associated with it, i need the stored procedure to create the a single row in the publication table and then recognise that multiple authors need to be inserted into the linking table for that single PublicationID. For this i have a listbox with multiple selection =true. At the moment with the storedprocedure below it is creating two rows in PublicaitonID, and then inserting two rows into PublicationAuthors with only the first selected Author from the listbox??? Can anyone help???ALTER PROCEDURE dbo.StoredProcedureTest2 @publicationID Int=null,@typeID smallint=null, @title nvarchar(MAX)=null,@authorID smallint=null AS BEGIN TRANSACTION SET NOCOUNT ON DECLARE @ERROR Int --Create a new publication entry INSERT INTO Publication (typeID, title) VALUES (@typeID, @title) --Obtain the ID of the created publication SET @publicationID = @@IDENTITY SET @ERROR = @@ERROR --Create new entry in linking table PublicationAuthors INSERT INTO PublicationAuthors (publicationID, authorID) VALUES (@publicationID, @authorID) SET @ERROR = @@ERROR IF (@ERROR<>0) ROLLBACK TRANSACTION ELSE COMMIT TRANSACTION

I am attempting to create a stored procedure that will launch at report runtime to summarize data in a table into a table that will reflect period data using an array type field. I know how to execute one line but I am not sure how to run the script so that it not only summarizes the data below but also creates and drops the table.
I have a column defined as smalldatetime. Default length (4), and "allow NULLS" is checked.In the Enterprise Manager UI, when i enter data into that table row, if i just tab past that column, all is well, and the value is represented in the UI as <NULL>.The problem comes once i ever enter a date into that column. Say i have entered a date (all is well), and now i want to remove that entry and go back to NULL (after the date value has been committed, different entry session, say).How is that done?It seems to me, once a date has ever been entered into that column, now, if i try to remove it, i get the error "The value you entered is not consistant with the data type or length of the column, or over grid buffer limit". I have tried deleting the value, entering spaces, entering the string NULL or the string <NULL>; maybe some other tries as well, but none works, i always get that error message and am not allowed to proceed past that cell until i restore a date value to it. I want to get back to <NULL>.Anybody know?Thank you.Tom
I am stuck on finding a solution to transpose source data from a system via a metadata look-up table into a destination table. I need a method to transpose/pivot the source data into columns (which are by various data-types). The datatypes for each column are listed in a metadata table.
Source Data Table:
Table Name: Source
SrcID AGE City Date 01 32 London 01-01-2013 02 35 Lagos 02-01-2013 03 36 NY 03-01-2013
Metadata Table:
Table Name:Metadata
MetaID Column_Name Column_type 11 AGE col_integer 22 City col_character 33 Date col_date
Destination table:
The source data to be loaded into the destination table(as shown below):
I have SQL Server Management Studio Express (SSMS Express) and SQL Server 2005 Express (SS Express) installed in my Windows XP Pro PC that is on Microsoft Windows NT 4 LAN System. My Computer Administrator grants me the Administror Privilege to use my PC. I tried to use SQLQuery.sql (see the code below) to create a table "LabResults" and insert 20 data (values) into the table. I got Error Messages 102 and 156 when I did "Parse" or "Execute". This is my first time to apply the data type 'decimal' and the "VALUES" into the table. I do not know what is wrong with the 'decimal' and how to add the "VALUES": (1) Do I put the precision and scale of the decimal wrong? (2) Do I have to use "GO" after each "VALUES"? Please help and advise.
Thanks in advance,
Scott Chang

I'm trying to insert data into a table from two tables into a single table along with a hard coded value.
insert into TABLE1 (THING,PERSONORGROUP,ACCESSRIGHTS) VALUES ((select SYSTEM_ID from TABLE2 where AUTHOR IN (select SYSTEM_ID from TABLE2 where USER_ID =('USER1'))),(select SYSTEM_ID from TABLE2 where USER_ID =('USER2')),255)

Subquery returned more than 1 value. This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression.
What is the best way to transfer data from the staging table into the main table.
Example: Staging Table Name: TableA_satge (# of rows - millions) Main Table Name: TableA_main (# of rows - billions)
Note: Staging table may have some data same as the main table.
Currently I am doing: - Load data into staging table (TableA_stage) - Remove any duplication of rows from the staging table (TableA_stage) - Disable all indexes on main table (TableA_main) - Insert into main table (TableA_main) from staging table (TableA_stage) - Remove any duplication of rows from the main table using CTE (TableA_main) - Rebuild indexes on main_table (TableA_main)
The problem with the above method is that, it takes a lot of time and log file size grows very big.
I am trying to insert bulk data into main table from staging table in sql server 2012. If any error comes, this total activity is rollbacked. I don't want that to happen. I want to know the records where ever the problem persists, and the rest has to be inserted.
