Hi,
How do I quick remove all the documentation generated in the
catalog by sp_primary and sp_foreignkey.
The documentation is misleading and does not correspond with the current primary and foreign keys. I do not wish to drop and create the
tables.
Hello
I tried the Beta 1 of the service pack 1 to .net 3.5. If I try to add an entity (and try to save this), I get the Exception "No support for server-generated keys and server-generated values".
How can I add entities to my Sqlce- database?
I tried to give the id- column (primary key) in the database an identity, another time without identity, only primary key --> none of them worked. I always get the same error.
What do I have to change to make successfully a SaveChanges()?
Thanks for your help,
Gerald

We have implemented a very small reporting database which has a main table that started off small and has now grown to around half a million rows. Initially, there were no indexes on the table apart from a clustered index, but as the data has grown, performance has dropped and so we have added a number of indexes. This has resolved the performance issues.
Before creating the indexes SQL Server had auto created a number of statistic objects (_WA_Sys_000... etc). After creating the indexes, new statistic objects where created for the new indexes. In some cases, there are duplicate statistics (auto and index) for the same columns.Should I go through and drop the duplicate auto statistics? Will having duplicates cause issues at all?
We have a database with hundreds of tables, each with "CreatedByLoginId" and "ModifiedByLoginId" FK columns back to the Login table. Â This is all fine and well, but 500+ tables all link back to Login table every time a record is inserted or updated.
For strictly performance reasons, what do you think of us REMOVING the FK constraints on all of our tables? Â While this does mean that a GUID that is not a valid LoginId could potentially be put in a table, I'm not too worried about it because users don't have direct access to the database.
Hello again,
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,
teacher_id
INT
NOT NULL,
class_title
VARCHAR(50)
NOT NULL,
class_grade
SMALLINT
NOT NULL
DEFAULT 6,
class_tardies
SMALLINT
NOT NULL
DEFAULT 0,
class_absences
SMALLINT
NOT NULL
DEFAULT 0,
CONSTRAINT Teacher_instructs_ClassFKIndex1 FOREIGN KEY (teacher_id)
REFERENCES Users (user_id)
)
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,
teacher_id
INT
NOT NULL,
grade_id
INT
NOT NULL,
CONSTRAINT Grades_for_ClassesFKIndex1 FOREIGN KEY (grade_id)
REFERENCES Grades (grade_id),
CONSTRAINT Classes_have_gradesFKIndex2 FOREIGN KEY (class_id, teacher_id)
REFERENCES Classes (class_id, teacher_id)
)
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?
Thank you for your assistance.
what the best practice is for creating indexes on columns that are foreign keys to the primary keys of other tables. For example:
[Schools] [Students]
---------------- -----------------
| SchoolId PK|<-. | StudentId PK|
| SchoolName | '--| SchoolId |
---------------- | StudentName |
-----------------
The foreign key above is as:
ALTER TABLE [Students] WITH CHECK ADD CONSTRAINT [FK_Students_Schools]
FOREIGN KEY([SchoolId]) REFERENCES [Schools] ([SchoolId])
What kind of index would ensure best performance for INSERTs/UPDATEs, so that SQL Server can most efficiently check the FK constraints? Would it be simply:
CREATE INDEX IX_Students_SchlId ON Students (SchoolId)
Or
CREATE INDEX IX_Students_SchlId ON Students (SchoolId, StudentId)
In other words, what's best practice for adding an index which best supports a Foreign Key constraint?
Pls let me know How I generate script for All primary keys and foreign keys in a table. Thereafter that can be used to add primary keys and foreign keys in another databse with same structure.
Also how I script default and other constraints of a table?
Can somebody explain to me how to best do inserts where you have primary keys and foreign keys.l'm battling.
Is there an article on primary keys/Pk ?
Hello!I have a table A with fields id,startdate and other fields. id and startdateare in the primary key.In the table B I want to introduce a Foreign key to field id of table A.Is this possible? If yes, which kind of key I have to build in table A?Thx in advance,Fritz

I have uninstalled the CTP version of the SQL Server express so that I can install the released version but CTP version is still listed in the add/remove program list but without the change/remove button. I have been to different sites to find information on cleaning this up and I have ran all the uninstall tool I can find but the problem still prevails. I cannot install the released version without completely getting rid of the CTP version. Please help anyone.

I need help,
I am having a hard time removing my SQL instance inside the Add/Remove program. After i select the SQL Instance name and then I tried to remove it but it won't allow me to delete it. There isn't any error message or whatsoever. Actually, when i try to log it in my SQL Management studio, that certain sql instance name is not existing according to the message box. Is there any way to remove the Sql Instance in my system?
I appreciate your help, Thanks

Hi,
I have recently been looking at a database and wondered if anyone can tell me what the advantages are supporting a unique collumn, which can essentially be seen as the primary key, with an identity seed integer primary key.
For example:
id [unique integer auto incremented primary key - not null],
ClientCode [unique index varchar - not null],
name [varchar null],
surname [varchar null]
isn't it just better to use ClientCode as the primary key straight of because when one references the above table, it can be done easier with the ClientCode since you dont have to do a lookup on the ClientCode everytime.

Hello,
I've a problem with auto-generated key. In my parent table, some lines have been deleted. I would like to add new lines with the same content in order to restore my database, but I cannot decide on the id value which is an auto-generated key. Is there a solution to set an auto-generated key with a specific value ?
Thank you in advance,

Suppose I want to generate a table as below
No. Col1 Col2
1 100 Alan
2 110 Alan
3 120 Alan
In Column I there is a sequence of numbers from 1 to 3 with a step of 1
In Column 2 there is a sequence of numbers from 100 to 120 with a step of 2
In Column 3 there is a name that is repeated accross the whole column
Can I generate such a table with just a single SQL Statement . I don't see any reason why it should not be possible. We know the logic to generate all the numbers of every row. It would be possible using a while loop , but that is be tedious and I am looking for a better way.
One application I can think of is, Suppose I want to find out all deleted primary key ids from a table or say if I have a set
(1,2,3, 7,8,9) , and wish to know the missing numbers in the range 1 to 9. If an sql like above is possible I could use it in a left join to get me the desired output.
Could anyone tell me if it is possible and if not , why not ?
Thanks,

Hi,
Is there any way to look at behind-the-scene SQL query that gets generated by SSRS engine to pull the data out of the data source (particularly SQL Server).
So far, I only know that you can see the query generated by semantic query engine by changing trace option in configuration file.
Thanks and Regards,

Hi
I have a windows application. I am using following code right after setting the LocalReport ReportPath. Report rendering is too slow if use following line of code and Report viewer does not show spiny and the text that says €œReport is being generated.€?
Me.ReportViewer1.SetDisplayMode(DisplayMode.PrintLayout)
Me.ReportViewer1.ZoomMode = ZoomMode.Percent
Me.ReportViewer1.ZoomPercent = 80
Please advise how can make it fast and show spiny.
Thanks in advance.
I have created a report and deployed it successfully to a seperate machine with SSRS on. Both my dev machine and the SSRS machine are in the same workgroup. I can then Browse to the Report Manager though IE and click & run the report (The connection is using integrated security). The report requires a single parameter to be entered which once done works successfully. The report has a single table, an inbedded image and a few static fields in the report header.
If I however add a report viewer control to an aspx test form all is not well. As soon as the page opens I am prompted to enter the parameter which is good news as it shows there has been some communication with the SSRS metabase. I then click the view report button. Using Profiler I have proved that the report Stored Proc. is running with the correct parameter value. The report viewer however seems to hang and only displays "Report is being generated" without displaying the results. It does this even with a timeout set of 1000ms.
I don't think this is a security issue as both the Report Manager works and the test form prompts me for the parameter and effectively runs the report SP. I can only assume it is a problem with returning the report to the browser.
Does anyone have any insight?

Hi,
I created a PDA application with a database, which has a table with a uniqueidentifier field and primarykey.
While doing the bulk insert from dataset into sql mobile database, It is inserting the record but it is not inserting the id which was entered into the sql server 2005 database, instead the id by creating a new id and the code is as below.
conAdap = new SqlCeDataAdapter(strQuery, conSqlceConnection);
SqlCeCommandBuilder cmdBuilder = new SqlCeCommandBuilder(conAdap);
conAdap.Fill(dsData);
int r =conAdap.Update(dsData);
Please help me.

Hi,
I have a report which doesn't work. It has a datatset based on a store procedure. The store-procedure take 10 to 50 second to execute, depending on the parameters.
But, I can't never see my report as i wait more than 10 minutes and it's never generated.
So, I have think that maybe it could be because of the matrix inside the report, so I have try to create another report which have the same dataset but with nothing inside, just a textbox, and it doesn't work too !!
So now, i'm very disapointed and I don't know what to do !
Someone can help me please ? It's very important.
Thank you.
I created a new DataSet object using the
wizard and had no probs, it's very straightforward. I created a
GetProducts() method and also added a GetProductCount() method. I
read somewhere that when the DataSet is saved, it will generate the
TableAdapter classes and store them in the project nested under the
DataSet object. This isn't happening, the files aren't there and
yes I'm displaying all files. There *is* however the TableAdapter
class but it's in not in the project, it's a temporary file w/ the
following path:
C:WINDOWSMicrosoft.NETFrameworkv2.0.50727Temporary ASP.NET
Fileswebsitef38f8b5500014aeSources_App_Codepw_products.xsd.72cecc2a.cs.
I saved the DataSet several times, compiled the entire solution and
even closed the solution yet this temporary file isn't getting saved
where it should be. Does anyone have any ideas abt this?
I'm eager to start developing my DAL and def want to use these
TableAdapter classes.
Thx in advance,

I ran a SP that lists fragmented tables in our DB which listed almost all the tables and indexes in the DB. The list includes index names that start with "_WA_Sys_tablecolumn name_.....". Are these SQL Server generated indexes or are these statitics on the tables? What are they? If these are system generated indexes as I thought they were, how are they generated? Can these indexes be dropped or should one want to? IF so, how? Any effect on the DB performance if dropped?
Thanks for your advise.

I am using Enterprise Manager to generate a script of the stored procedures on my database. Under File|Options, I selected Windows Text(ANSI). The file which is generated contains all stored procedures, but there are some procedures which are so long that they wrap to the next line.
When I then try to run this script from ISQL in a batch file, those procedures which wrap error out. Is there any way to generate the script in a more formatted manor, avoiding the wrapping?
I'm having trouble getting the namespaces correct in the XML that is generated by SQL. The XML consists of two parts: a header part with some context information and the payload part with the actual data. With my current SQL script, the namespace is also copied to the payload part.
Here are some DDL and DML scripts to generate two test tables and some test data:
Code:
CREATE TABLE dbo.context(
idintNOT NULLconstraint pk_dbo_context primary key,
namenvarchar(100)NOT NULL
)
INSERT INTO dbo.context(id, name) VALUES (1, 'Here comes some great context information.')
[Code] ....
This is my current FOR XML script that generates the XML:
Code:
;WITH XMLNAMESPACES (DEFAULT 'http://services.registersubscription-02_00.a.cool.url.com')
SELECT
CEXT.name AS [Context/Name],
(SELECT
CONT.id AS [Content/Reference],
[Code] ....
This generates this XML (notice that the namespace is repetated in the <Questions> element):
Code:
<RegisterSubscription xmlns="http://services.registersubscription-02_00.a.cool.url.com">
<Request>
<Context>
<Name>Here comes some great context information.</Name>
[Code] ....
The XML should be like this:
Code:
<RegisterSubscription xmlns="http://services.registersubscription-02_00.a.cool.url.com">
<Request xmlns="">
<Context>
<Name>Here comes some great context information.</Name>
[Code] ....
The generated XML does not pass the XSD validation.
