How To Do A Join Using Foreign Keys In Stored In A Database Column?
Apr 17, 2007I have a database column that stores a comma delimited list of foreignkeys. Would someone show me how to do a join using the values from alist stored within a record?For example, a record in tbl_cds.genre_id might have a value of "2,5, 6" corresponding to genre_ids 2 , 5 and 6. I want to jointbl_cds.genre_id to tbl_genre.genre_id using the values in that datafield.It seems I need a loop like this:SELECT * FROM tbl_cdsWHEREBegin Looptbl_cds.genre_id[i] = tbl_genre.genre_idEnd Loop.Would someone give me the correct syntax?Is there an alternative method that would create less overhead?Sorry for such a novice post.

Creating Inter-table Relationships Using Primary Keys/Foreign Keys Problem
Apr 11, 2006Hello 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.
Creating Indexes On Columns That Are Foreign Keys To Primary Keys Of Other Tables
Jul 16, 2014what 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?

Sysindexes SQL 6.5
Oct 3, 2001When you have a table with no indexes you can see the table name in sysindexes and the relevant data in the rest of the fields with an indid of 0. I understand this bit.....but when you have created an index and then you delete it again.... the row in sysindexes just has the tablename and no other data?
Weird or by design?

Sysindexes Don't Match
Sep 7, 2004It seems my sysindexes table is inaccurate on a nonclustered index. In my case the rowcount (rows and rowcnt) do not match the actual rowcount of the table. The command UPDATE STATISTICS doesn't change the rows or rowcount, adding 'FULSLCAN' won't budge rowcount either.
After I did a dbcc reindex, the number of rows matched, however, upon adding rows in the table both rows and rowcount are out of sync again.
It's a fairly straightforward table, no triggers, no computed fields, only integer, datetime, varchar and bigint columns. There's a clustered index on a bigint column and a nonclustered index on a integer column.
dbcc show_statistics show that the nonclustered index is updated and it's rows and rows sampled match the number of rows in the table (not in the sysindexes-table).
I'd like to know if I'm chasing ghosts here or if there's something very wrong here. What could be causing the counts being inaccurate? Anyone who could shed some light?
Query Sysindexes
Jun 3, 2007i hav a table, Test1, with a clustered index and two non clustered index defined on it.
When i use sp_help Test1, the CI and non clustered index are listed along with the column names.
when i query the sysindex table (for id = object_id(Test1))
i can see entries like _WA_Sys_<<ColumnName>>_3D5EEB29.
what are these entries? are they indexes? if yes, how these entries are created and what is the significance of these entries.
Pl discuss.

Could Not Find Row In Sysindexes For Database
Aug 26, 2007I am trying to attach a database that was created on another server. I believe the database was created using SQL Server Management Studio Express 2005. Now, I have successfully attached the database in my development environment, which is using SQL Server Management Studio Express 2005.
However, when I tried to attach the database onto our production server, which is SQL Server 2000 I received the error:
Error 602:Could not find row in sysindexes for database ID 18, object ID 1, index ID 1. Run DBCC CheckTable on sysindexes.
In my development environment, I ran DBCC CheckDB on the source database and no errors are returned.
I aslo checked the compatibility level under the database properties and it shows: Sql Server 2000 (80)
So, this should not be a version incompatibility issue. What is causing the attach to fail on SQL Server 2000?
Thanks for any help.

DBCC Error In Sysindexes
Oct 10, 2006I have some errors in my DB, we do have a backup plan in place, but the person who put it in place is no longer here. It's all automated and running, the problem is , we do A LOT of transactions a day, and the error has been in the db since 9/20(2.5 weeks) when someone shut the power off accidentally. So i'm reluctant to do a backup, mainly since i have NO idea how to do one, we do full and incremental, full on weekend, incremental weeknights.
below is the biggest problem SYSINDEXES :(. a few other tables had problems but DBCC with repair_allow_data_loss has fixed those with 'hardly' any data loss. What can I do here?

How Do You Determine An Index Is Unique From Sysindexes?
Mar 17, 2002I need to write a script which will respond differently if a table's index forces uniqueness.
I am using SQL 7.0 and I am using the [sysindexes] table of my database to examine those indexes. I am using the [id] field from the [sysobjects] table for the table I am examining and I am using that [id] field to find like-valued [id] fields in the [sysindexes] table.
My problem is that I can't seem to determine, from an examination of the [sysindexes] table, whether, or not, an index is unique.
When adding an index, and checking the unique property of that index, the values that I get in the [status] field of [sysindexes] are different from the values which are supposed to show, at least according to the sysindexes (T-SQL) entry in SQL Server Books Online.
For instance, I have a table which combines two text fields which comprise the only key on a table. The unique and clustered boxes are checked in the index setup screen. When I look in the [sysindexes] table, the value in the [status] field is 2113554, which is not a value I see in the books online page. According to my books online page, a unique index should have a value of 2 in the [status] field and a clustered index should have a value of 16 in the [status] field. My assumption is that I should see a value of 18 in that [status] field, not 2113554.
I looks like the books online entry might be out-of-date because the field that is labeled [reserved1] in my books online page, is labeled [StatVersion] in my actual [sysindexes] table. That [StatVersion] field looks suspiciously like a Status Version field, possibly indicating that the Status field has undergone some sort of version revision?
Is anyone familiar with this stuff?
Thanks.

Duplicate Names In Sysindexes Table

I notice that one of the indexes has a status = 2097154 and a indid of 2 while the other has a status of 0 and a indid of 0. I believe these are duplicates. Anybody have an idea if these really are and what the status and indid fields mean?

How To Replace Sysindexes And Sysobjects In The Query For Sql Server 2005?
Feb 26, 2008hi all,i was using the system tables namely sysindexes and sysobjects in sql server 2000. But now sql server 2005 is using instead of sql server 2000. Since am using sysindexes and sysobjects, too much time is taking for the execution in sql server 2005. So I need to change the query suitable for sql server 2005.I have read in msdn that the system tables are replaced with corresponding catalog views in sql server 2005. The catelog view for sysobjects is sys.objects. plz check the link http://technet.microsoft.com/en-us/library/ms187997.aspxCould anyone please tell me how to replace the sysindexes and sysobjects in the query without rewriting the query too much. If I can replacesysobjects with just sys.objects, then it will be very helpful. Is it possible? And what about sysindexes. Any help anyone could give would be greatly appreciated!
View 8 Replies View RelatedAuto Incremented Integer Primary Keys Vs Varchar Primary Keys
Aug 13, 2007Hi,
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.
Regards

now iam a fresh graduate as i learned from uni if i want to get the couses that each student took i would make a table called studentcouse(id,cno) and put the two of them pk
now iam working and at work they told me to do so:studentcouse(studentcouse_serial,id,cno) studentcouse_serial=pk .but i told them that dublicate filed may occur amd they told me that we have a function that will remove dublicate.
so iam asking u if who is right me or them and if u can tell yr comments
thanx a lot
