Hmmm... I'm not sure what the cause is really. If you hard code the entire SQL statement (just for testing problems, does the error still occur?

I've also found this, which might be useful:

Do you have a typo? It looks like either the ProposalSystem database doesn't exist or it has some problems with it. Did you delete some system tables from this database?

Agent Job error

I'm using SQL Server 2005 and when trying to create an Agent Job I get the following error:

Unable to cast object of type 'Microsoft.SqlServer.Management.Smo.SimpleObjectKey' to type 'Microsoft.SqlServer.Management.Smo.Agent.JobObjectKey'. (Microsoft.SqlServer.Smo)<br />

I've googled it but the only solution provided was to repair the SQL Native Client, which didn't solve my problem.
Any ideas what else should I try?

Hi all,

Few days back an interviwer asked me an SQL question. I searched the answer in the net, but i cant able to find it. Plz any one help me. The question is"How and where will you store the records retrived from an table temporarily in the database", he asked me without creating an table, how to store the records retrived (using select query) from an table to temporavery table, actually there is no such an table, in other word that temporavery table is an virtual table.

Can any one suggest me the answer plz.

Thanks in advance

You can create a temporary table by prefixing the name with # which which create a table for that user in the TempDb database on the SQL server, meaning that each user will have their own copy

You can also do global temporary tables as well if you need to.

SQL Database Backup

Hi,

I'm trying to write a small application in VB6 to backup and restore databases. I have looked up the code in the SQL Server Books Online but it keeps on giving me an SQL error.

I have tried 2 different forms of code ... see below with the error.

1)
SQL
USE master
EXEC sp_addumpdevice 'disk', 'APDB', DISK ='C:\SQLBCKUTIL\DatabaseBackups\05Jul2007_101009_APDB.dat', 2

ERROR
Incorrect syntax near the keyword 'DISK'.

2)
SQL
BACKUP DATABASE APDB
TO DISK = 'C:\SQLBCKUTIL\DatabaseBackups\05Jul2007_101009_APDB.BAK'
WITH FORMAT,
NAME = 'Full Backup of APDB'

ERROR
Cannot open backup device 'C:\SQLBCKUTIL\DatabaseBackups\05Jul2007_101009_APCON.BAK'. Device error or device off-line. See the SQL Server error log for more details.
BACKUP DATABASE is terminating abnormally.

Anyone have any ideas?

Cheers for now,
Allan

Composite Primary keys - A question

vagl4-Jul-07 23:00

4-Jul-07 23:00

Hi,

I have question on usage of composite primary keys. I know it is suggested not to use them for performance reasons (wide indexes). But when it comes to enforcing the integrity constraints, composite keys help me.

Scenario:
I have the following tables.
Projects and Employees.

These tables share a m:n relationship and there is an intermediary table called "ProjectAssignments" with the following structure.

ProjectID, EmployeeID, EmpRole, AssignedBy, AssignedOn. (Primary Key: ProjectID & EmployeeID)

Employees with reviewer role, review the tasks of their reviewees on the specified date. This is captured with the following structure.

ReviewID, ProjectID, EmployeeID_Reviewer, EmployeeID_Reviewee, ReviewDate, TaskDesc. (PrimaryKey: ReviewID)

I would like the design to enforce the constraint that reviewer and reviewee are on the same project. I have defined the foreign keys as follows.

FOREIGN KEY([PRJ_ID], [EMP_ID_Reviewee]) REFERENCES [dbo].[ProjectAssignments] ([AGN_PRJ_ID], [AGN_EMP_ID])
FOREIGN KEY([PRJ_ID], [EMP_ID_Reviewer]) REFERENCES [dbo].[ProjectAssignments] ([AGN_PRJ_ID], [AGN_EMP_ID])

Is this is a good design?

The other alternative I thought has the following design. But, this does not enforce the above mentioned constraint.

Table ProjectAssignments: AssignID, ProjectID, EmployeeID, EmpRole, AssignedBy, AssignedOn. (Primary Key: AssignID)
(Unique Constraint: ProjectID, EmployeeID)

Table ProjectReviews:
ReviewID, AssignID_Reviewer, AssignIDReviewee, ReviewDate, ReviewTask. (Primary Key: ReviewID)

Which one should I prefer and why? I Unsure | :~

Thanks,
AGL

I prefer the second one. I assume that the reviewer is reviewing an employees actions on a particular project so I would revamp the ProjectReviews to look like this:

ReviewID (PK),
AssignID (FK - ProjectAssignment),
ReviewerEmployeeID (FK - Employee),
RevieweeEmployeeID (FK - Employee),
ReviewDate,
ReviewTask

The reason I would choose your second method is for maintenance reasons. I could look at the column structures and pretty much tell what links to what without having look too deeply into the FK constrants. This makes things much easier 2 years down the road.

I would enforce the relationship of the Reviewer/reviewee & AssignId in the ProjectReviews via a stored proceedure (or trigger). You could add deeper FK relationships to manage this for you but, the nature of the data does not seem to make it necessary. If a reviewer gets hit by a car and is removed from a project, is it necessary to remove all of his/her reviews? Only you can answer questions like that.

If you are expecting millions of records, then the second method will execute joins faster because of the smaller keys. If your database is small, the time saved will not be noticeable.

change the query to

so that the date is incloded in single quotes
