hello
I am working with an existing database and there is no Foreign key between 2 tables
how can i create a FK after , when the tables are allready full ?
product :
product_id
report_id
name
report :
report_id
dateR
i want to create a FK on product.report_id, and ON DELETE CASCADE
thank you
I have been asked to create PK on many tables using a query on all tables where we do not have clustered indexes. Some of the tables contains PK but non-clustered. If in a table there are no PK, then how to decide on which column PK can be created? can we do it with the query without data loss and without human intervention?

Quick question, I hope, I am trying to create a table that has a column that is a nested table in SQL Server 2005 Express Edition. Any ideas how I could go about doing this?

I'm working on an ASP.Net project where I want to test code on a localmachine using a local database as a back-end, and then export it tothe production machine where it uses the hosting provider's SQL Serverdatabase on the back-end. Is there a way to export tables from oneSQL Server database to another in such a way that if a table alreadyexists in the destination database, it will be updated to reflect thechanges to the local table, without existing data in the destinationtable being lost? e.g. suppose I change some tables in my localdatabase by adding new fields. Can I "export" these changes to thedestination database so that the new fields will be added to thedestination tables (and filled in with default values), without losingdata in the destination tables?If I run the DTS Import/Export Wizard that comes with SQL Server andchoose "Copy table(s) and view(s) from the source database" and choosethe tables I want to copy, there is apparently no option *not* to copythe data, and since I don't want to copy the data, that choice doesn'twork. If instead of "Copy table(s) and view(s) from the sourcedatabase", I choose "Copy objects and data between SQL Serverdatabases", then on the following options I can uncheck the "CopyData" box to prevent data being copied. But for the "CreateDestination Objects" choices, I have to uncheck "Drop destinationobjects first" since I don't want to lose the existing data. But whenI uncheck that and try to do the copy, I get collisions between theproperties of the local table and the existing destination table,e.g.:"Table 'wbuser' already has a primary key defined on it."Is there no way to do what I want using the DTS Import/Export Wizard?Can it be done some other way?-Bennett

View 2 Replies View RelatedI have the full blown Microsoft SQL Server Management Studio (MSSMS) installed on my workstation.
We have a number of existing databases that I'd like to manage with MSSMS and put into source control.
How do I get MSSMS to "import" or "Convert" an existing SQL server 2000 database into a project that I can manage with MSSMS? We have not used Source safe up to this point, but would like to start doing so now.
This seems like it ought to be explained well up front in any discussion of converting from SQL 2000 to SQL 2005 or installing 2005, but I can't find ANYTHING useful in the BOL or other help.
Thanks for any help you can give me.

This is a SQL question while using Microsoft SMS.
I am trying to write a SQL query looking for a specific file in a specific directory. If the File does not exist, then I want it to display.
here is the Code that I have for it that shows that the file exists... how do I make it show that the file doesn't exist?... what am I doing wrong?
Thanks for all your help in advance!
**********************************
SELECT TOP 100 PERCENT SYS.Netbios_Name0, SYS.User_Name0, SF.FileName, SF.FileVersion, SF.FileSize, SF.FileModifiedDate, SF.FilePath,

I have 2 views which contain the following fields:
EVENT,
WEEK,
SUBSCRIPTION,
QTY,
GROSS_AMOUNT,
SEASON
The 2 views differ by SEASON. I'm attempting to combine the 2 views in to a single view or table grouping by EVENT, WEEK and SUBSCRIPTION:
EVENT,
WEEK,
SUBSCRIPTION,
Q6 (qty of season 1),
A6 (gross_amount of season 1),
Q7 (qty of season 2),
A7 (gross_amount of season 2)
Below is my select command:
------
SELECT TOP 100 PERCENT
dbo.vw_SEASON06.EVENT,
SUM(dbo.vw_SEASON06.QTY) AS Q6, SUM(dbo.vw_SEASON06.GROSS_AMOUNT) AS A6,
SUM(dbo.vw_SEASON07.QTY) AS Q7, SUM(dbo.vw_SEASON07.GROSS_AMOUNT) AS A7,
dbo.vw_SEASON06.WEEK,
dbo.vw_SEASON06.SUBSCRIPTION
FROM dbo.vw_SEASON06 FULL OUTER JOIN
dbo.vw_SEASON07 ON dbo.vw_SEASON06.WEEK = dbo.vw_SEASON07.WEEK AND
dbo.vw_SEASON06.SUBSCRIPTION= dbo.vw_SEASON07.SUBSCRIPTION AND
dbo.vw_SEASON06.EVENT = dbo.vw_SEASON07.EVENT
GROUP BY
dbo.vw_SEASON06.EVENT,
dbo.vw_SEASON06.WEEK,
dbo.vw_SEASON06.SUBSCRIPTION
ORDER BY
dbo.vw_SEASON06.EVENT
-----
This creates the view but there are some issues. If an 'EVENT' exists in dbo.vw_SEASON07.EVENT and doesn't exist in dbo.vw_SEASON06.EVENT the value of the field 'EVENT' is set to NULL because the 'EVENT' name is returned from dbo.vw_SEASON06.EVENT. The same issue exists for 'SUBSCRIPTIONS' and 'WEEK'.
How can I create a single view/table that will include all the data from these 2 views without the NULL values in EVENT or SUBSCRIPTION?
Any help is appreciated!
I am looking for a way to create a temp column who's value would take the value of another column and prepend a value like this to it "domain". This is the Select statement I currently have:
SELECT Nalphakey,[Last Name],[First Name],[User Name],[E-mail Address],[User Name]
FROM SkywardUserProfiles
I understand how to create an Alias for an existing column, but not sure how to do what I am wanting. I also understand that the following will do the concatenation that I need, but I have only used it in an UPDATE query, and I'm not sure how to use it within a Select statement or if that's even possible:
domainName=CONCAT('domain',User Name);

I've been handed a very old database to knock into shape for an ASP.NET energy monitoring website. The current tables seem to have been created as cross tabs from the meter raw data, and are in the form-
CREATE TABLE [dbo].[PW_Table] ( [Date] [int] NULL , [Meter_1] [float] NULL , [Meter_2] [float] NULL , [Meter_3] [float] NULL , [Meter_4] [float] NULL , [Meter_5] [float] NULL , [Meter_6] [float] NULL , [Meter_7] [float] NULL) ON [PRIMARY]
I'd like to rearrange them into the format-
ReadingID (Identity), ReadingDate (datetime), ReadingValue (float), MeterID (int)
I would set up a lookup table for the Meters and join on MeterID.
Converting the date value from an int into a DateTime is no problem, but I can't work out how to transpose the meter readings. Can anyone point me towards a way of doing this via SQL, or would it need to be done by hand?
Thanks in advance for any help offered.
I have three tables :
England_Summer_2001
England_Summer_2002
England_Summer_2003
The tables have the following columns :
Player, Position, [From], [To], Fee, Type, ID, League, Window
I want to create a new table, EnglandFinal with all the data from the three tables although I'm guessing it would not be a good idea to copy the primary keys (ID column) as they would clash.
I have played around with CREATE and INSERT into and UNION but I get various errors. I'm sure I've done this before!
This creates a table from a single table :
select * into Final
from England_Summer_2001
Hi guys , assuming right now I already create partition function (PF_Date) and partition scheme (PS_Date). Let say I would like to implement the partition on the existing tables ( eg: transaction table which is in PRIMARY filegroup), how am I switch it from PRIMARY to PS_Date ? Is it I have to re-create the particular table then only able to put in the partition scheme? Hope can get any assistance here. Thanks alot.

I need to populate tables in my MS SQL 2000 DB with content from an excel file. I am not sure how this is done or how to format the excel file. If someone could help me with this it would be much appreciated!Thanks!
View 3 Replies View RelatedHello Friends,
I am right now working on a project that has a database with over 100 tables in a database. Because of extreme time constraints the developers didn't build in any relationships or constraints between or in the tables. Now I need to remodel the database such that the database is more structured and normalized. I don't have much knowledge about the database design since it is a 2 year old application and the person who developed the database is now gone. I know remodelling the database would require knowledge of the existing database and business rules.
I was wondering if there are any tools that could suggest or discover relationships between tables. For eg. Lets say there are two tables named 'Customer' and 'Order'. I notice that there is a column named 'id' in Customer and a column named 'customer_id' in Order. So I ask the tool to discover a relationship between id and customer_id and it tells me that there is a one-one or one-many or no relationship by comparing values. I heard ERWin would be able to do that but thats expensive. Please do let me know asap.
I have a real table with an identity column and a trigger to populate this column.
I need to import / massage data for data loads from a different format, so I have a temp table defined that contains only the columns that are represented in the data file so I can bulk insert.
I then alter this table to add all the other columns so that it reflects all the columns in the real table. I then populate all the values so that this contains the data I need.
I then want to insert into the real table pushing the data from the temp table, however this gives me errors stating that the query returned multiple rows.
I specified all the columns in the insert grouping as well as on the select from the temp table.
ANY thoughts / comments are appreciated. This is beginning to drive me nuts.

Is there a method of forcing existing tables into the in-memory filegroup so the table data can benefit from in-memory processing.
View 7 Replies View RelatedWe have an existing BI/DW process that adds large chunks of data daily (~10M rows) to an existing table, as well as using Deletes to remove stale data. This scenario seems to beg for partitioning to support switching in/out data.
After lots of reading on this, I have figured out the mechanics of the switching, bit I still have some unknowns about the indexes needed to support this.
The table currently has several non-clustered indexes, including one on the partitioning column - let's call that column snapshotdate. Fortunately there are no FKs involved, and no constraints.
Most of the partitioning material I see focuses on creating a clustered PK to assist with switching. Not sure if this is actually necessary, but assume I create one using an Identity column (currently missing) plus snapshotdate.
For the other non-clustered, non-unique indexes, can I just add the snapshotdate to the end of the index? i.e. will that satisfy the switching requirement?
I normalized the below tables but I am finding it difficult to copy data to the new tables. How do I copy data from existing table to the normalized tables? see the table structure below and other supporting information:
SKU_DATA(SKU,SKU_Description,Department,Buyer) Note: this table already has data in it.
CREATE TABLE SKU_DATA (
SKU
Integer NOT
NULL,
[code].....
The table structure above have two three determinants( SKU,SKU_Description and Buyer). SKU and SKU_Description are candidate keys. Primary key is SKU.
Normalization : SKU_DATA(SKU,SKU_Description, Buyer)
BUYER(Buyer,Department)
1. I need to make use of in memory engine for my pr-existed develop procedures ,tables ,index. do I need and code changes for application and how to store tables /indexes in OLTP memory
Assume table index may have primary key index as well.
2. If table with one primary index and 2 foreign constraints, 3 non clusters indexed. which one able o load to memory area and how t do that.
3. In memory is lock free zone. usually locks will happpen in RDMS context . how this works without locks.
I am new at the development stages of my DBA career and I am stumped on how to approach this problem, any help would be great.
Problem: Our web developer is designing a Software survey that ranks the difficulty of tasks within a software application like MS Word. Each of these tasks have a rank tied to them.
Here are the tables that he created.
Table 1
EmpID Text
123456 A1, A2, A3
Table 2
ValueID Text Rank
A1 Create Table 1
A2 Insert Query 5
In the text field of table 1 he inserts every task or valueid that the employee is able to do.
He needs to be able to select Empid, text(from table 2), and Rank. Based on need. An example would be 'Which employees can Insert a query'. And he would need to be able to look in the text string on Table 1 and find every A2 in listed then get empid and rank. I know that it can be done with full text searching, however I guess what I want to know is if there is another way to create tables that would jus make a join necessary where the value id can be tied to the empid for each task the employee is able to do?
I hope that this makes sense!!
Chris writes "How do I create a copy of a table (not temporary).
In Oracle I do .
Create table newtable as select * from oldtable
This command copies data and column data types.
I tried entering
SELECT * INTO db2.dbo.newtable FROM db1.dbo.oldtable
in the query manager and it appears to create the new table, but it only seems to be a temporary table because when I leave query manager and check my data base it isn't there.

I have an Access 2000 MDB with ODBC linked tables to a SQL Server 7 backend. I currently have a selections table in the front end file which theusers use to make selections of records. The table has two fields -- primarykey (which matches primary key of main, SQL Server table), and a booleanfield. The table is linked to the main table in a heterogeneous inner join.I'm looking to move the table to the back end, while still giving eachmachine a unique set of selections. Using one large table with machine nameas part of the primary key actually slows things down. So I'm consideringusing a series of tables, where each machine has its own table in the backend for selections. The machine name would be incorporated in the particularselections table name, and the front end link would be modified on the flywhen the database is opened to point to that machine's back end selectionstable.This would require having about 50-100 individual selections tables in theback end database. Also, if a machine doesn't have a table when the databaseis opened on that machine, then that table would be created on the fly,populated, and pointed to via the ODBC link.Anyone see any problems with this approach, specifically creating the tableon the fly and then immediately using it, as well as having that many littletables running around? Thanks for any input!Neil

I went to look at the connection string previously entered for a dataset created in a new report, and am not seeing anything intuitive for bringing up the associated datasource dialog box that was used to enter name, type and connection string. I'm also noticing nothing intuitive for deleting an existing dataset. How do you do these two very simple things in an existing project? I dont see the dataset in solution explorer, I see it only in the text box on the data tab and in a limited kind of way on the dataset view where the columns show and maint is allowed mostly on the columns only. I tried hilighting the dataset here and hitting the delete key to no avail.

Those topics are stored in table A above. My users can just read the messages associated with the topic and rate that message. The rating is then stored in table B.Now i will like my users to search for topics with a particular word or sentence in table A and the topics that are returned have a rating they specify. My procedure takes the word or sentence to search in table A and and the rating which will be used in table B. I will like to construct another table that has this newly searched results and return it using a stored procedure or anything simple. I dont know how to do this because i have very little knowledge in stored procedures or sql..... Any help(Code) will be greatly appreciated...
