I want to write an online database that displays 4-generation pedigrees. Can anyone point me to a tutorial/web site on how to do this? I've written several online databases in asp, but can't figure out how to do this particular algorithm. Any help appreciated.
Basically I have a list of about 400,000 horses each with a unique ID code. In each individual horses record there is its mother and father identified by their ID codes. ie; three columns, the horse's ID, and it's mother and father's ID. So, when you display a horses four generation chart, it should all link uphorse, mother father, grandparents, great-grandparents etc.. It should be a common database task, but Ive searched everywhere on the web and in various books and cant find how to write and link up the SQL statements. Any help/pointers would be appreciated. cheersYour table design should be similar to the following:
Horse Id,Horse Detail,Fathers Id, Mothers Id
Using SELF JOIN (Relating the table to itself by aliasing) you can derive any number of elements in a hierarchy.
e.g. Data
Horse Id | Horse Detail | Father Id | Mother Id
1 | ABC | |
2 | DEF | |
3 | GHI |1 |2
4 | JKL |1 |2
5 | MNO | |
6 | PQR |1 |5
An addtional field Sex (F/M) may be useful for your application
Hope this helps.

PDF file
Can SSRS write reports in PDF files? What about multiple reports in a single PDF file? Thanks.Yes - PDF is an output type. You can create multiple reports and join them in one 'master' report as subreport objects to return them all in one file.|||Please kindly provide related tutorial links. Thanks.

Pattern matching with multiple values
I want to check for multiple patterns in a particular column.
For one pattern I can write e.g.
SELECT * FROM <TablName> WHERE ColumnName LIKE '%abcd%'.
My requirment is to select all rows for which column value matches with many patterns.I will fetch the patterns in a subquery
e.g. (SELECT '%'+name+'%' FROM <TableName>)
Any thoughts?
HiIt might work if you move your like into Exists , like
SELECT * FROM <TableName> T1
WHERE EXISTS (SELECT * FROM T2
WHERE T1.column LIKE '%' + T2.NAME + '%'
)
NB.|||
Thanks for your solution !
|||Thanks for your solution !
However my problem won't get solved this way. Actually I am building anSSRS report and the subquery was meant to be the 'Available Values ' of a multi-valued Input parameter.
When the user selects one or more params SRS will form a string of the values like " 'val1','val2','val3'...."
In my case SRS is forming a WHERE clause like
.........
.........
WHERE colname in ('val1','val2','val3'). This would search for the exact string, whereas I would like it to only match with patterns like '%val1%','%val2%','%val3%'.
i think you need to build it as
WHERE colname like '%val1%' or colname like '%val2%' or colname like '%val3%'.
|||Thnx. Shallu.....That is correct syntax, but you need to see that the number of values is not static and all of them are stored as one parameter by ssrs.
To simplify it for you, say SSRS is providing me with a string series like " '%val2%', '%val2%' ,'%val2%' ...". Now I need to use this to do my comparison.
|||HiThere might be a better solution from SSRS comunity , you should try your question there as well. From T_SQL point of view you could try following solution:
Create 2 store procedures : one - master that recived your string of parameters , parses a string into a list of single parameters and collects whatever children return , the other one - child , that can process one parameter at a time
CREATE PROCEDURE MultipleParameterSearch_procedure
@.intString varchar ()
as
CREATE TABLE #reultset (<your columns>)
DECLARE @.PARAMETER
-- parse your string into separate parameters , one at a time
...
...
WHILE @.PARAMETER is not nul
BEGIN
-- accumulate your single parameter procedure results
INSERT INTO #reultset (<your columns>)
EXEC SingleParameterSeach_Procedure @.PARAMETER
-- get next parameter
END
SELECT * FROM #reultset
RETURN
GO
CREATE PROCEDURE SingleParameterSeach_Procedure @.Parameter VARCHAR()
AS
SELECT <your columns>FROM <Table> WHERE Column LIKE '%' + @.Parameter + '%'
RETURN
GO|||Hi
Just one last suggestion.
LIKE %val%' is a very expensive operation, as no indexes can be used to help QueryOptimiser to make a quick search. Adding multiple LIKE parameters are going to decrease performance of your query. If you are doing your Report for production , explain to the user implications and pesweid them to use a single-parameter select .
:-).NB|||Thanks for taking the pains .I'll follow this up 
Please take a look at the link below:
http://www.sommarskog.se/arrays-in-sql.html
It discusses various techniques to process lists using SQL. You can use one of those methods to generate a table that contains the individual values and then use it as source in the EXISTS sub-query.

Passing table-type variables to SP?
Sorry about posting twice, but I had some trouble with setting the date on
this machine...
I would like to write a stored procedure that takes a table (i.e. table
variable) as its parameter.
E.g.:
DECLARE @.mytable = TABLE(ID INT, NAME VARCHAR(50))
SP_MYPROC @.mytable
What should SP_MYPROC's signature look like? I can't seem to be able to find
anything about this in the documenation.
I guess it would look something like this:
ALTER PROCEDURE SP_MYPROC
(@.t TABLE)
or
ALTER PROCEDURE SP_MYPROC
(@.t TABLE(ID INT, NAME VARCHAR(50)))
Actually, how big is the freedom when taking such a parameter? Is it enough
to use the first version and treat the table whatever way I would like to?
E.g. not assuming that the 'NAME' column is a VARCHAR(50), but taking
any tables the second column of which is of type VARCHAR of any size.
Hi
You can not pass a table data type to a stored procedure. You may want to
use temporary tables instead.
From Books online "Create procedure" topic
CREATE PROC [ EDURE ] [ owner. ] procedure_name [ ; number ]
[ { @.parameter data_type }
[ VARYING ] [ = default ] [ OUTPUT ]

[ FOR REPLICATION ]
AS sql_statement [ ...n ]
data_type
Is the parameter data type. All data types, except the table data type, can
be used as a parameter for a stored procedure. However, the cursor data type
can be used only on OUTPUT parameters. When you specify a data type of
cursor, the VARYING and OUTPUT keywords must also be specified. For more
information about SQL Server - supplied data types and their syntax, see

Passing table-type variables to SP?
Sorry about posting twice, but I had some trouble with setting the date on
this machine...
I would like to write a stored procedure that takes a table (i.e. table
variable) as its parameter.
E.g.:
DECLARE @.mytable = TABLE(ID INT, NAME VARCHAR(50))
SP_MYPROC @.mytable
What should SP_MYPROC's signature look like? I can't seem to be able to find
anything about this in the documenation.
I guess it would look something like this:
ALTER PROCEDURE SP_MYPROC
(@.t TABLE)
or
ALTER PROCEDURE SP_MYPROC
(@.t TABLE(ID INT, NAME VARCHAR(50)))
Actually, how big is the freedom when taking such a parameter? Is it enough
to use the first version and treat the table whatever way I would like to?
E.g. not assuming that the 'NAME' column is a VARCHAR(50), but taking
any tables the second column of which is of type VARCHAR of any size.Hi
You can not pass a table data type to a stored procedure. You may want to
use temporary tables instead.
From Books online "Create procedure" topic

data_type
Is the parameter data type. All data types, except the table data type, can
be used as a parameter for a stored procedure. However, the cursor data type
can be used only on OUTPUT parameters. When you specify a data type of
cursor, the VARYING and OUTPUT keywords must also be specified. For more
information about SQL Server - supplied data types and their syntax, see

passing table name into a stored procedure
Is it possible to write is a stored procedure that passes a table name into
a
stored procedure?
select * from @.tablenameThe short answer is use slow, proprietrary dynamic SQL to kludge a
query together on the fly with your table name in the FROM clause.
The right answer is never pass a table name as a parameter. You need
to understand the basic idea of a data model and what a table means in
implementing a data model. Go back to basics. What is a table? A
model of a set of entities or relationships. EACH TABLE SHOULD BE A
DIFFERENT KIND OF ENTITY. What having a generic procedure works
equally on automobiles, octopi or Britney Spear's discology is saying
that your applications a disaster of design.
1) This is dangerous because some user can insert pretty much whatever
they wish -- consider the string 'Foobar; DELETE FROM Foobar; SELECT *
FROM Floob' in your statement string.
2) It says that you have no idea what you are doing, so you are giving
control of the application to any user, present or future. Remember
the basics of Software Engineering? Modules need weak coupling and
strong cohesion, etc. This is far more fundamental than just SQL; it
has to do with learning to programming at all.
3) If you have tables with the same structure which represent the same
kind of entities, then your schema is not orthogonal. Look up what
Chris Date has to say about this design flaw. Look up the term
attribute splitting.
4) You might have failed to tell the difference between data and
meta-data. The SQL engine has routines for that stuff and applications
do not work at that level, if you want to have any data integrity.
Yes, you can write a program with dynamic SQL to kludge something like
this. It will last about a year in production and then your data
integrity is shot.

implementing a data model. Go back to basics. What is a table? A
model of a set of entities or relationships. EACH TABLE SHOULD BE A
DIFFERENT KIND OF ENTITY. What having a generic procedure works
equally on automobiles, octopi or Britney Spear's discology is saying
that your applications a disaster of design.
1) This is dangerous because some user can insert pretty much whatever
they wish -- consider the string 'Foobar; DELETE FROM Foobar; SELECT *
FROM Floob' in your statement string.
2) It says that you have no idea what you are doing, so you are giving
control of the application to any user, present or future. Remember
the basics of Software Engineering? Modules need weak coupling and
strong cohesion, etc. This is far more fundamental than just SQL; it
has to do with learning to programming at all.
3) If you have tables with the same structure which represent the same
kind of entities, then your schema is not orthogonal. Look up what
Chris Date has to say about this design flaw. Look up the term
attribute splitting.
4) You might have failed to tell the difference between data and
meta-data. The SQL engine has routines for that stuff and applications
do not work at that level, if you want to have any data integrity.
Yes, you can write a program with dynamic SQL to kludge something like
this. It will last about a year in production and then your data
integrity is shot.
