Data Structure -- It's Been A While
Jul 20, 2005
Ok, I haven't been doing too much database work lately and my brain has gone
soft.
I need some help with proper structure.
My database is being used to track television shows.
Any given show will be associated with at least one production company (call
it ProdCo) but possibly up to 3 production companies (never more than that).
I have:
tblNetwork
NetID (numeric, Identity)
NetName (char, 50)
tblShowData
BookingNum (numeric, Identity)
BookingNumExt (numeric, Identity)
Now, if I was just dealing with one ProdCo I would add it tblShowData as a
foreign key from tblNetwork; no problem.
How do I structure it so that I can combine 1 to 3 ProdCo's as one reference
in tblShowData.
I tried:
tblNetworkCombo
ID (numeric, Identity)
Net1
Net2
Net3
The problem is, obviously I can only join the FK from tblNetworks to one of
the NetX fields in tblNetworkCombo.
I don't quite know where to go from here. Any help would be appreciated.

i have a database on one server that I want to duplicate on a new server. I do not want to copy the data only the structure.
I created some SQL scripts from the current db as I have read that is what I should do.
My question is where do I use this script on my new server to create the new tables etc..
Do i use the import feature. Where do I run my sql script?
thanks

I have a database (MSSQL). To demonstrate the problem let me show a fictive Tablestructure. I don't want to discuss about how to save the data differntly, because the structure is fix and I can't change it.To get this result I would do a sql query with a lot of joins like that:
SELECT firstname, lastname, email.value, phone.value
FROM Customer
INNER JOIN
(
SELECT Customer_Properties.id, Customer_Properties.value
FROM Customer_Properties
[code]...
I don't think that this is really performant and the SQL-Queries get very complicated. Give it a other methode for that? I can't change the data structure.

I have a SQL 2005 database that I am using with a website. This basic website will be sold to other companies and ran on their servers with different URLs. Since, All of these databases will store different data, I'm not sure how I can make updates to original database and replicate those structure changes to the other DBs without changing the data also. Is there a way to automate the replication of structural DB changes without replicating the data along with it?
Thanks,
Kirk

We have SQL Enterprise Manager (8.0). Is there any way to Copy a Table from one database to another with only the Structure (design) - not all the Data?
I can't find any option in the Import Data Wizard that only copies the Table structure.
Any help is appreciated. Thanks

I have written 5 content-management systems and am getting a little bored writing a lot of the same functionality and tweaking it for different datamodels. Is there a way within .NET to have visibility of a database's structure (ie, data type, column names, foreign keys etc)? I'd like to write up a dynamically generated form for any given table, displaying appropriate form controls based on data type and foreign keys.

new to SQL Server 2000. We have an obsolete database that we need to
save off for x number of years. DB2 has utilities (DB2Look/Export)
that allows for the export of the data along with a schema and script
that enables the future recreation of the structure of the databases
and tables to include RI etc. You can save off the architecture and
relationships of the tables as well as the data.
Does SQL Server have anything similar?
Failing that, our plan is to backup the data and logs then image the entire disk.
Thanks in advance.

Hi all!I have an application that needs to copy the database structure fromone database to another without using the "Generate SQL Script"function in Enterprise Manager. I'd like to do this from within astored procedure. Can someone recommend the best approach for this?I've seen references to using SQL-DMO from a stored procedure using thesp_OA* procs in other postings to this group but was wondering if therewas an easier way? Can I use bcp and then use xp_cmdshell from withinmy stored procedure? It's not clear to me from the documentationwhether bcp copies both structure and data or just data? Is there abetter way?Thanks in advance for any help!Karen

Hi SQL gurus,I have a table structure question. I will have a table 'Models' thathas one to many 'incomes' and one to many 'costs'. These 2 entitieshave exactly the same structure, which is 7 smallmoney and a name. Isit better to create a table 'Incomes' and a table 'Costs', with boththe same number of fields like this :Incomes-------------in_idmodelin_1in_2in_3in_4in_5in_6in_7in_nameCosts-------------c_idmodelc_1c_2c_3c_4c_5c_6c_7c_nameor is it better to create one single table that will contain bothentities like that :Incomes_Costs-------------ic_idmodelic_1ic_2ic_3ic_4ic_5ic_6ic_7ic_nameic_isIncomewhich only differs from the 2 above by the isIncome field to know whichrow is an income and which row is a cost.I'd like to know which method is the best in terms of performance andgeneral structure and would greatly appreciate if you explain a littlethe reasons that drove you to suggest me a method over the other.Thanks all for your time!ibiza

Hi guys,
Hopefully this is the right place to ask.
Basically we have have two larges databases, one of which is updated from the other monthly.
For exaplination purposes:
DB1 = Source DB
DB2 = Destination DB
The problem that I require a soltion to is, how do I insert rows from a table in DB1 to DB2 and recover and store the identity of the new row against the ID of the existing row. This is so that I can then matain constraints when it comes to inserting rows into the next table and the next and so on.
This process of storing the ID's as lookups will need to be done for almost every table of which there are 20.
The best Idea we have at the minute is to create a table with two colums for each table (drop it and recreate it after each table has exported) that contains the two ID's, new and old.
This will require using a cursor for each row in the existing table, inserting it in the new table and the using @@Scope_Identity to get the new ID and then insert the two values into the temp table.
This too me feels like it will be very slow, particuarly when I bear in mind how much data we have.
Does anyone have any better ideas? (Sorry if the explaination isn't great, its difficult to get accross)
Thanks
Ed

I have been working on my windows app, using SQL Server 2005 (& C#) but I now have loads of junk data, so I want to copy the structure without any data to a new set of files that can become the production version.
I assume I can use backup and restore in future when I want a copy of my production data to use for future testing.
How would I take just one table from my test database and add it to my production database without retyping the design?
Apart from the size limitation is there any advantage in buying a version of SQL Server over using the Express edition?

I'm looking to create a new version of a database but with completely reloaded data - so I want to retain the database structure but none of the data.
Is there an easy way (read: without a DBA on staff) to copy an existing database structure - preferably with views and stored procedures - and not take the data along for the ride?
Thanks in advance for suggestions...!

In order to export data to a 3rd party provider, I build five separate tables to store the data. Every table has a different layout, except for the first four columns. They are record type, SSN, employee id and another id number.
Basically, I have to sort that data by SSN then by record type. Each employee will have multiple records.
However, that data will need to be "merged" into one table to be exported.
I have created a table that defines the first four columns, but then has one large "filler" field that will contain the rest of the data. How can I copy data from five different tables with five different layouts into one table?
Any suggestions?
Thanks,
Steve Hanzelman

We have the following scenario: We receive CSV files every month for which SSIS packages were built to process the data. The following problems occur from time to time:
1. The structure of the CSV file changed (e.g. column added or removed)
2. There were no footers in the data, but now footers started to appear
3. Date format changed (e.g. used to be mm/dd/yyyy, but became mm.dd.yyyy)
4. Number format changed (e.g. from 2000 to 2,000)
Currently we have person who manually opens each file, and using our "validation document" validates to ensure none of these or similar problems occur. We would like to move away from this manual process if possible. I understand that items 3. and 4. could be caught by loading data into a staging table with VARCHAR data types, and performing validation before moving it any further.
Item 2 is a bit questionable (meaning depending on the footer size SSIS load could fail or not).
Item 1, however, is a sure fail of the SSIS package that directly loads the data into a table.
Thus I feel the two possible options are:
1. Create a custom script that will run through the file, row by row, apply all the necessary validations and report an error or continue if all checks out
2. Use some 3rd party tool to validate the files (semi-manually) before kicking off the SSIS processing.

Is there a way to copy the structure from one database to anotherwithout affecting the actual data?For example, I added new fields and stored procedures to a db in mydevelopment environment. There are a lot of them.I now want to make the same changes to my production environment db butdon't want to affect the data. Only the fields, stored procs &constraints and stuff pertaining to the structure of the db should bechanged.Does anyone know of a program that can do this or can this be done inMS SQL Enterprise Manager.Any help would be appreciated.7078895

I have a large fact table spread across tens of partitions (appx. 1TB each). I found that the business does not need much of the columns in the table. So, as an optimization action, I decided to get rid of these un-needed columns.What is the efficient way to achieve this? Can I simply drop these columns from the table, or use a new table with the reduced structure?

Is it possible to purge all records in the database while retaining the the table structures. Even better yet, could I do it on a table by table basis? If I simply delete all the records the identities for the tables do not revert back to 1.

I have created two table with same data structure. I need realtime effects (i.e. data) on both tables - Table1 & Table2.
Following Points to Consider.
1. Both tables are in the same database.
2. Table1 is using for data entry & I wants the same data in the Table2.
3. If any row insert, update & delete occers on Table1, the same effect should be done on Table2.
4. I need real time data insert, update & delete on Table2.
I knew that using triggers it could be possible, I have successfully created a trigger for inserting new rows (using logical table "Inserted") in Table2 but not succeed for update & delete yet.
I want to understand how can I impletement this successfully without any ambiguity.
I have attached data structure for tables. Thanx...

Hello. I want to ask about the possibility of copying both a tablestructure and it's contents from aSQL server table to a table within MS access. The problem cannot besolve with a permanent table structure at the target location.The names of the columns are essentially data with the application andso are subject to change. I am targeting a solution using SQL QueryManager.The approach I have tried (with failure) isSELECT *INTO <linkedserver table>FROM <local table>This should create and copy. However, I am not sure if this isachievable with this approach.Refer to the dialogue;-------------------------------------------------------USE MASTERGOEXEC sp_addlinkedserver@SERVER = 'Freddie',@PROVIDER = 'Microsoft.Jet.OLEDB.4.0',@SRVPRODUCT = 'OLE DB Provider for Jet',@DATASRC = 'C: empHMIS_Recipe.mdb'-- I am not sure if this is requiredEXEC sp_addlinkedsrvlogin 'Freddie', false, 'sa', 'Admin', NULLSELECT * FROM Freddie...FRED -- This is OKSELECT * INTO #Temp FROM Freddie...FRED -- This is OK-- This fails - Refer errorSELECT * INTO Freddie.FRED65from #tempServer: Msg 2760, Level 16, State 1, Line 1Specified owner name 'Freddie' either does not exist or you do not havepermission to use it.-- This also fails and I thought reflected the above select with naming- Refer errorSELECT * INTO Freddie...FRED65from #tempServer: Msg 117, Level 15, State 1, Line 2The object name 'Freddie...' contains more than the maximum number ofprefixes. The maximum is 2.EXEC sp_dropserver 'Freddie',@droplogins = 'droplogins'------------------------------------------------------------Thank you.Regards JC...

I am able to use a custom script task to receive a MSMQ package and save the package contents to a flat file.
I can also use the bulk load task to push the flat file contents into a SQL table.
However, I would like to save the package contents to a variable (done, it works), and then pass that string variable to a data flow task for SQL upload. In other words, I don't see any reason to persist the msmq package contents to disk.
My question is: Which data flow source can I use that will accept a string variable? The string variable will then need to be processed with bulk load or an execute sql task.
Btw, the content of the string variable is a csv style string:
"01001","11/21/2006",15
"01001","11/21/2006",1
"01001","11/21/2006",25
"01001","11/21/2006",3
Thanks,
Trey

Hoping someone will have a solution for this error
Errors in the metadata manager. The data type of the '~CaseDetail ~MG-Fact Voic~6' measure must be the same as its source data type. This is because the aggregate function is not set to count or distinct count.
Is the problem due to the data type of the column used in the mining structure is Long, and the underlying field in the cube has a type of BigInt,or am I barking up the wrong tree?

Hi all!
I am trying to organize a hierarchical data structure into a table. I need to have the possibility to set 2 parents for some nodes. Curently I see following two options:
Example 1
id parent_id name-----------------------------------1 0 Level 1 Parent A2 0 Level 1 Parent B3 1,2 Level 2 Child
Example 2
id parent_id name-----------------------------------1 0 Level 1 Parent A2 0 Level 1 Parent B3 1 Level 2 Child3 2 Level 2 Child
Is any of the two examples valid database logic wise? In fact, is it possible to achieve the requirement by using only one table?
