Newby JOIN Question
Nov 14, 2006
I'm attempting to use a JOIN for the first time and I'm getting about 94,000 rows returned when I should only be getting about 270. Something must not be unique (possible DSN) but I can't figure out why the join is not working. I know it must be difficult to determine the problem without actually seeing the tables but could somebody with a lot of SQL experience spot any glaring problems with this query? Thanks!
SELECT DS.DSNName AS DSN,
S.ServerName AS WebServer,
DBs.DBName,
A.ServerName AS SQLServer
FROM DSNs DS,
Servers S,
DBs,
DSNs LEFT OUTER JOIN Servers A
ON DSNs.SQLServerID = S.ServerID
WHERE DBs.Status = 1
AND DS.WebserverID = S.ServerID
AND DBs.DBID = DS.DBID
ORDER BY DSN

to create a code.
Hi everyone,
I have SQL SERVER 2005 on my desktop and i need to run queries from remote machines on my SQL SERVER.
I thought it would be a good i idea to create a web page on my machine to where remote users can contact and activate SQL QUERIES.
My question is very simple and i wonder i a simple answer is available:
How do i run SQL queries whereby ASP code ?
How do i make a connection between a web page (.asp code) and a SQL sever ?
If the answer is complicated as i'm afraid it is, could any one provide me a link for a tutorial dealing with the above issues ?
Thanks a lot !

Hi,I am trying to set up a DTS Package to transfer data from a remoteMySQL server to a local MS SQL database. The source tables will remainstatic as will the destination however I only want to copy down datathat does not already exist in the local database.I have two different methods of which to identify the new rows, on sometables it is by a unique ID thus in TSQL I would say WHERE ID x.Other tables are by date where I would want to do something like WHERECreateDate >= GetDate()-1How would I go about performing such clauses using DTS?ThanksMike

Hi,I'm enclosed a snippet of test code which highlights my problem. The Storedprocedure insertValue should insert text into the parent, then insert othertext into the child table but the 2 tables should auto increment in sync(i.e. so that they both end up with the same id numbers). I've tried takingthe auto increment out of the child table but then I don't know how to getthe right parent id into the child table.Any advice appreciated - this is my first database, so I'm just in thelearning process really. Code follows:CREATE TABLE Parent(id INTEGER DEFAULT AUTOINCREMENT,parenttext VARCHAR(16),PRIMARY KEY (id))!CREATE TABLE Child(childID INTEGER INTEGER DEFAULT AUTOINCREMENT,childtext VARCHAR(16),FOREIGN KEY (childid) REFERENCES Parent(id),PRIMARY KEY (childID))!CREATE PROCEDURE insertValues(in p VARCHAR(16), in c VARCHAR(16))BEGINinsert into parent (parenttext) values (p);insert into child (childtext) values (c);END!call insertValues('from parent', 'from child')!select * from parent, child where parent.id = child.childid!

This has all the earmarks of a procedural error on my part. I have it occuring on two computers with the same sequence and exceptions and with clean databases. Note: The code is from Doug Lowe's ASP.NET 2.0 Everyday Apps For Dummies 2006 loaded from the CD. The database is generate from a script provided by the author. I will paste it in at the end.

This Q is so easy I can't find the answer anywhere!
Why is SQL Server called 'Server' ? I understand it is a lot more capable and robust than Access but where does 'server' come into it.
I currently use ASP and Access for dynamic websites but it is time to move up a notch.
Do I just buy SQL Server, make a database, upload it to the same place as before and hey presto?
can I run lots of websites (on different domains and servers) from databases created with my single license standard edition?
Thanks

Hello All,
I'm hoping you all can provide me with a little advice? I just landed my first DBA position with a company that runs different versions of SQL Server (7.0, 2000, 2005) on many different boxes. The databases I will be managing are in the 10-30TB ranges. Mostly the databases are for OLAP access by the company’s customers. I will need to bring myself up to speed on everything because there is no DBA at the company to transfer information.
Can anyone provide any advise on how I should approach this task of learning my position and/or useful links to resources? Thank you in advance!

I imagine a data-retrieval scenario where data destined for several different tables are collected and initially placed into one 'collector' table (say, ALLDATA); a stored procedure then kicks in and passes the records to individual destinations. For example, I might want to have data for two persons, Ann and Betty, come in and be routed to table_ann and table_betty respectively, with the correspondence stored in table LOOKUP:
id output_table
Ann table_ann
Betty table_betty
How could this be implemented? Perhaps with some kind of loop over the rows of LOOKUP, with table name retrieved and entered into a (EXEC-written?) query
insert into <table_name>
from alldata
where id in (select distinct id
from lookup
where output_table = <table_name>)
But how could one iterate over the list of table names? (These could be placed in table, of course, and the question become 'how could one iterate over a table's rows?')
I hope that this is an easy question for SQL Server pros, and will be grateful for a brief pointer/code snippet. (I may have given more background then necessary, but perhaps there are better solutions available there as well?)
Thanks a lot!

Im not sure how to explain this or if this is the correct forum but here it goes.
I have created a report from a view that gives me court hearing dates on a defendent. When I run the report/view I get two different dates for the person such as, 12/14/2006 and 12/15/2006. How can I get it to show only the later date (12/15/2006)? I pull information from a mainframe that almost always gives me 2 different dates, but we only need the most recent date.
Here is my query for the view
SELECT dbo.CASES.CaseID, dbo.CASENUMBERS.CaseNumber AS Arrest_Number, dbo.CASENUMBERTYPES.CaseNumTypeCode AS Arrest_NumType,

(dbo.DEFCHARGES.OffenseDate > CONVERT(DATETIME, '2006-01-01 00:00:00', 102))
In the 'PRE-HEARING SET' table is where I receive the two dates. Is there a way to filter out the first date? I just want to show the most recent date.

I need copy one database from one server into another server.
Both servers have SQLSERVER 2000.
One way is copy the LDF files directly but I need to stop the engine to do that, I€™m sure there are many other ways more efficiently.
I do need an advice.
Thanks in advance

I was writing a query using both left outer join and inner join. And the query was ....
SELECT
       S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname
FROM
       Production.Suppliers AS S LEFT OUTER JOIN
      (Production.Products AS P
        INNER JOIN Production.Categories AS C
[code]....
However ,the result that i got was correct.But when i did the same query using the left outer join in both the cases
i.e..
SELECT
       S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname
FROM
       Production.Suppliers AS S LEFT OUTER JOIN
(Production.Products AS P
LEFT OUTER JOIN Production.Categories AS C
ON C.categoryid = P.categoryid)
ON
S.supplierid = P.supplierid
WHERE
S.country = N'Japan';
The result i got was same,i.e
supplier   country   productid   productname   unitprice   categorynameSupplier QOVFD   Japan   9   Product AOZBW   97.00   Meat/PoultrySupplier QOVFD   Japan  10   Product YHXGE   31.00   SeafoodSupplier QOVFD   Japan  74   Product BKAZJ   10.00   ProduceSupplier QWUSF   Japan   13   Product POXFU   6.00   SeafoodSupplier QWUSF   Japan   14   Product PWCJB   23.25   ProduceSupplier QWUSF   Japan   15   Product KSZOI   15.50   CondimentsSupplier XYZ   Japan   NULL   NULL   NULL   NULLSupplier XYZ   Japan   NULL   NULL   NULL   NULL
and this time also i got the same result.My question is that is there any specific reason to use inner join when join the third table and not the left outer join.

All other rows are joining as expected.

I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.
For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.
The carid (primary key) and carmodelname belong to the Cars table.
The makeid and orderdate belong to the OrderDetails table.
The productname and carcategory belong to the Product table.
The number of rows returned should be the same as the number of rows in OrderDetails.

I have a merge join (full outer join) task in a data flow. The left input comes from a flat file source and then a script transformation which does some custom grouping. The right input comes from an oledb source. The script transformation output is asynchronous (SynchronousInputID=0). The left input has many more rows (200,000+) than the right input (2,500). I run it from VS 2005 by right-click/execute on the data flow task. The merge join remains yellow and the task never finishes. I do see a row count above the flat file destination that reaches a certain number and seems to get stuck there. When I test with a smaller file on the left it works OK. Any suggestions?

I'm using SQL Server 2005.
A piece of software I wrote starting timing out on a query that left outer joins a table to a view. Both the table and view have approximately the same number of rows (about 170000).
The table has 2 very similar columns, one is a varchar(1) and another is varchar(100). Neither are included in any index and beyond the size difference, the columns have the same properties. One of the employees here uses the varchar(1) column (called miscsearch) to tag large sets of rows to perform some action on. In this case, he had set 9000 rows miscsearch value to "g". The query then should join the table and view for all rows where miscsearch is set to g in the table. This query takes at least 20 minutes to run (I stopped it at this point).
If I remove the "where" clause and join all rows in the two tables, the query completes in about 20 seconds. If set the varchar(100) column (called descrip) to "g" for the same rows set via miscsearch, the query completes in about 20 seconds.
If I force the join type to a hash join, the query completes using miscsearch in about 30 seconds.
So, this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER HASH JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
and this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE descrip = 'g' ORDER BY balance DESC
But this does't:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
What should I be looking for here to understand why this is happening?
Thanks,
john

We are trying to migrate from sql 2005 to 2012. I am changing one of the implicit join to explicit join. As soon as I change the join, the number of rows returned are fewer than before.
Below is my Implict join query
INSERT #RIF_TEMP1 (rf1_row_no,rf1_rif, rf1_key_id_no, rf1_last_date, rf1_start_date)
SELECT currow.rf0_row_no, currow.rf0_rif, currow.rf0_key_id_no, prevrow.rf0_start_date, currow.rf0_start_date
FROM #RIF_TEMP0 currow , #RIF_TEMP0 prevrow
[Code] ....
and below is explict join query
INSERT #RIF_TEMP1 (rf1_row_no,rf1_rif, rf1_key_id_no, rf1_last_date, rf1_start_date)
SELECT currow.rf0_row_no, currow.rf0_rif, currow.rf0_key_id_no, prevrow.rf0_start_date, currow.rf0_start_date
FROM #RIF_TEMP0 currow LEFT JOIN #RIF_TEMP0 prevrow
ON (currow.rf0_row_no = prevrow.rf0_row_no + 1)
[Code] ....
the count returned from both the queries is different.
I am not sure what am I doing wrong. The count of #RIF_TEMP0 is always 32, it never changes, but the variable @countTemp is different for both the queries.

Why does this right join return the same results as using a left (or even a full join)?There are 470 records in Account, and there are 1611 records in Contact. But any join returns 793 records.
select Contact.firstname, Contact.lastname, Account.[Account Name]
from Contact
right join Account
on Contact.[Account Name] = Account.[Account Name]

Hi guys,
I'll appreciate any help with the following problem:
I need to retrieve data from 3 tables. 2 master tables and 1 transaction table.
1. Master table TBLOC contain 2 records :
rcd 1. S01
rcd 2. S02
2. Master table TBCODE contain 5 records:
rcd 1. C1
rcd 2. C2
rcd 3. C3
rcd 4. C4
rcd 5. C5
3. Transaction table TBITEM contain 4 records which link to 2 master table:
rcd 1. S01, C1, CAR
rcd 2. S01, C4, TOY
rcd 3. S01, C5, KEY
rcd 4. S02, C2, CAR
I use Left Join & Right Join to retrieve result below (using non-ASNI method) but it doesn't work.
Right Join method:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A RIGHT JOIN TBCODE B ON A.CODE = B.CODE
RIGHT JOIN TBLOC C ON A.LOC = C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
When I use Non-ASNI method it work:
SELECT C.LOC, B.CODE, A.ITEM FROM TBITEM A, TBCODE B, TBLOC C
WHERE A.CODE =* B.CODE AND A.LOC =* C.LOC
GROUP BY C.LOC, B.CODE, A.ITEM ORDER BY C.LOC, B.CODE
Result:
LOC CODE ITEM
-----------------------------
S01 C1 NULL
S01 C2 NULL
S01 C3 CAR
S01 C4 TOY
S01 C5 KEY
S02 C1 NULL
S02 C2 CAR
S02 C3 NULL
S02 C4 NULL
S02 C5 NULL
Please Help.

Is there a way to do a super-table join ie two table join with no matching criteria? I am pulling in a sheet from XL and joining to a table in SQLServer. The join should read something like €œfor every row in the sheet I need that row and a code from a table. 100 rows in the sheet merged with 10 codes from the table = 1000 result rows.
This is the simple sql (no join on the tables):
select 1.code, 2.rowdetail
from tblcodes 1, tblelements 2
But how to do this in SSIS?
Thanks - Ken

Hi,Just curious. Would you use ANSI style table joining or the 'oldfashion' table joining; especially if performance is the main concern?What I meant is illustrated below:ANSI Styleselect * from a join b on a.id = b.idOld Styleselect * from a, b where a.id = b.idI noticed that in some SQL, the ANSI is much faster but sometimes, theold style looks much better.It's ridiculous to try out both styles to see which is better wheneverwe want to write an SQL statement.Please comment.Thanks in advance.

Given a table of building components e.g. floors, walls, etc, etc:
create table component_multiplier_table
(
system_code char(4),
system_component_code char(3),
function_code char(4),
component_multiplier dec(7,6)
)
Where function_code is the function of the area e.g. Auditorium, Classrom, etc, etc. And not all components are available for all functions e.g. Carpeting is available for Classrooms but not Power Plants or Warehouses.
I need to self join the above table to itself on system_code and system_component_code and find out which rows are missing from each side.
A query that I've been banging away at with no success is:
SELECT c1.*, c2.*
FROM [dbo].[component_multiplier_table] c1 FULL OUTER JOIN [dbo].[component_multiplier_table] c2
ON (c1.system_component_code = c2.system_component_code) AND (c1.[system_code] = c2.[system_code])
WHERE c1.function_code = '2120' AND c2.[function_code] = '2750' AND (c1.[system_code] IS NULL OR c2.system_code IS NULL);
I added the is null conditions, no joy. I've tried every flavor of outer join w/o success.
Could any T-SQL gurus out there help me figure out how to do this in a set before I start coding
DECLARE crsr CURSOR
Thanks.
