Which way of retrieving a record is more effecient?:
Select tbl1.field1, tbl2.field1
from table1 tbl1 inner join table2 tbl2
on tbl1.id = tbl2.id
where someid = somevalue
and someid = somevalue
or
Select
field1 = (Select field1 from tabl1 where someid = somevalue),
field2 = (Select field2 from table2 where someid = somevalue)
Please help me with the efficient JOIN query to bring the below result :
create table pk1(col1 int)
create table pk2(col1 int)
create table pk3(col1 int)
create table fk(col1 int, col2 int NOT NULL, col3 int, col4 int)
insert into pk1 values(1)
insert into pk1 values(2)
insert into pk1 values(3)
insert into pk2 values(1)
insert into pk2 values(2)
insert into pk2 values(3)
insert into pk3 values(1)
insert into pk3 values(2)
insert into pk3 values(3)
insert into fk values(1, 1, null, 10)
insert into fk values(null, 1, 1, 20)
insert into fk values(1, 1,null, 30)
insert into fk values(1, 1, null, 40)
insert into fk values(1, 1, 1, 70)
insert into fk values(2, 3, 1, 60)
insert into fk values(1, 1, 1, 100)
insert into fk values(2, 2, 3, 80)
insert into fk values(null, 1, 2, 50)
insert into fk values(null, 1, 4, 150)
insert into fk values(5, 1, 2, 250)
insert into fk values(6, 7, 8, 350)
insert into fk values(10, 1, null, 450)
Below query will give the result :
select fk.* from fk inner join pk1 on pk1.col1 = fk.col1 inner join pk2 on pk2.col1 = fk.col2 inner join pk3 on pk3.col1 = fk.col3
Result :
+------+------+------+------+
| col1 | col2 | col3 | col4 |
+------+------+------+------+
| 1 | 1 | 1 | 70 |
| 2 | 3 | 1 | 60 |
| 1 | 1 | 1 | 100 |
| 2 | 2 | 3 | 80 |
+------+------+------+------+
But I require also the NULL values in col1 and col3
Hence doing the below :
select distinct fk.* from fk inner join pk1 on pk1.col1 = fk.col1 or fk.col1 is null inner join pk2 on pk2.col1 = fk.col2 inner join pk3 on pk3.col1 = fk.col3 or fk.col3 is null
+------+------+------+------+
| col1 | col2 | col3 | col4 |
+------+------+------+------+
| null | 1 | 1 | 20 |
| null | 1 | 2 | 50 |
| 1 | 1 | null | 10 |
| 1 | 1 | null | 30 |
| 1 | 1 | null | 40 |
| 1 | 1 | 1 | 70 |
| 1 | 1 | 1 | 100 |
| 2 | 2 | 3 | 80 |
| 2 | 3 | 1 | 60 |
+------+------+------+------+
The above is the reqd output, but the query will be very slow if there are more NULL valued rows in col1 and col3, since I need to also use distinct if I use 'IS NULL' check in JOIN.
Please let me know if there is an aliternative to this query which can return the same result set in an efficient manner.

Why would I use a left join instead of a inner join when the columns entered within the SELECT command determine what is displayed from the query results?

Here is the background for my question.
For my organization, I wrote a stored procedure to generate invoices for all of our clients using an audit table. Any time changes are made to the data in a table in our database, corresponding records are added to our audit table. Using this audit table we can recreate any table in the database as it was on a particular day. To generate the invoices, I first use the audit table to generate a cached view of the information. After I have a cached view, I insert records into an invoices table using various filters in my select statements.
When I run the T-SQL directly from query analizer, it takes about 1 minute to generate all of the invoices. However, when I run the same T-SQL as a stored procedure, it takes roughly 14 minutes to complete. Thinking there was a problem with too much parallelism, I restricted the MAXDOP to 2 (as the server has 2 physical processors). However, this did not reduce the execution time at all. Next, I tried using the sql profiler to watch the database while I ran the query. I checked and I did not see any unneeded recompilation. Oddly however, I noticed that the stored procedure required well over 2 million reads compared to only 400,000 reads using the straight T-SQL. I am at a loss for how to make my stored procedure run as efficiently as the straight T-SQL code. If anyone has anything else for me to try or has any suggestions, they would be greatly appreciated.
Thanks in advance,

The select command below will output one patient’s information in 1 row:
Patient id
Last name
First name
Address 1
OP Coverage Plan 1
OP Policy # 1
OP Coverage Plan 2
[code]...
This works great if there is at least one OP coverage. There are 3 tables in which to get information which are the patient table, the coverage table, and the coverage history table. The coverage table links to the patient table via pat_id and it tells me the patient's coverage plan and in which priority to bill. The coverage history table links to the patient and coverage table via patient id and coverage plan and it gives me the effective date.
select src.pat_id, lname, fname, addr1,
max(case when rn = 1 then src.coverage_plan_ end) as OP_Coverage1,
max(case when rn = 1 then src.policy_id end) as OP_Policy1,

Hello,
I'm writing a fairly involved stored procedure. In this Stored Procedure, I have an update statement, followed by a select statement. The results of the select statement should be effected by the previous update statement, but its not. When the stored procedure is finish, the update statement seemed to have worked though, so it is working.
I suspect I need something, like a GO statement, but that doesnt seem to work for a stored procedure. Can anyone offer some assistance?
What is the difference from performance point of view, when you select from 3 different tables to show fieldnames across the 3 tables based on one common key, OR using Join between the 3 tables.

I have three tables.
Quote
QuoteID, QuoteNumber,
Transportation
TransportationID, QuoteID, Item, Description, Cost
OptionalCharges
OptionalChargesID, QuoteID, Item, Description, Cost
What I want to do is SUM(Cost) for the Transportation and the Optional Charges table. If I do a normal INNER JOIN, with the SUM for Cost on the table Transportation and Optional Charges, it will SUM each twice. For example if Transportation has three rows with a cost of 10, 20, 30, it will SUM a total of 120 instead of 60.
So I came up with:
Select
Quote.QuoteID, QuoteDate, t.TransportationTotalCost
FROM
Quote.Quote
INNER JOIN
(
SELECT
QuoteID, SUM(COST) AS TransportationTotalCost
FROM
Quote.Transportation
GROUP BY
QuoteID
) t
on Quote.QuoteID = t.QuoteID
WHERE Quote.QuoteID = 135
Which gives me the total for the Transportation Table, but how do I go about adding in the Optional Charges Table?
Thanks,

Hi,
My SQL is a little rusty, and I need a little help for a client that I'm helping.
I'm simply trying to do create the following output:
HEADINGS: Sale Order | Customer Number | Customer Name | # of Pallets | (etc)
DATA: 456188 | 12355890 | Acme Customer | 4 | other stuff I have figured out that is irrelevant
This data comes from 3 tables:
1) SOE_HEADER
SALE_ORDER_NO | CUSTOMER_NO | (etc)
456188 | 12355890
2) CUST_NAME
CUSTOMER_NO | CUSTOMER_NAME | (etc)
456188 | Acme Customer
3) PALLETS_SALES_ORD
SALE_ORDER_NO | PALLET_ID | (etc)
456188 | 12345
456188 | 67890
456188 | 13579
I have 2 queries that independently pull the right data. 1 query joins the customer info to pull in the customer name, and the 2nd query calculates the # of pallets per sales order.
BUT I CAN'T GET THEM TO WORK WHEN I DO A JOIN!!! Can someone please help me? Here are the queries as I currently have them. This returns zero rows, but when I run my queries independently, the both return multiple rows with the correct data. PLEASE HELP ME!

Hello,
I'd appreciate any help with the following problem.
I'm trying to update a table using an inner self join.
I've a list of historical records with start dates, and I need to add end dates to the records, using the start date of the next record.
The table I'm using looks like this
CREATE TABLE [dbo].[IbesEstimateHist](
[IbesEstimateHistId] [int] IDENTITY(1,1) NOT NULL,
[IbesEstimateId] [int] NULL,
[EstimateDate] [datetime] NULL,
[EstimateEndDate] [datetime] NULL CONSTRAINT [DF_IbesEstimateHist_EstimateEndDate] DEFAULT ('9999-12-31 00:00.000'),
[Value] [decimal](13, 4) NULL,
CONSTRAINT [PK_IbesEstimateHist] PRIMARY KEY CLUSTERED
(
[IbesEstimateHistId] ASC
)WITH (PAD_INDEX = OFF, IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]
and here's some example data
insert into IbesEstimateHist
([IbesEstimateId],[EstimateDate],[EstimateEndDate],[Value])
values(1,'2006-01-01','9999-12-31',100)
insert into IbesEstimateHist
([IbesEstimateId],[EstimateDate],[EstimateEndDate],[Value] )
values (1,'2006-02-01','9999-12-31',100)
insert into IbesEstimateHist
([IbesEstimateId],[EstimateDate],[EstimateEndDate],[Value])
values (1,'2006-03-01','9999-12-31',100)
These are three historical records for the same estimate, I want to set the end dates of the earlier records to the start date of the next record that was recieved.
This is the SQL that I've tried using but I can't seem to get it right
select esth1.IbesEstimateId, esth1.EstimateEndDate,min(next.estimatedate)
from IbesEstimateHist esth1
inner join
(
select esth2.EstimateDate as estimatedate, esth2.IbesEstimateId
from IbesEstimateHist esth2
) as next
on esth1.IbesEstimateId = next.IbesEstimateId
and esth1.EstimateDate < next.estimatedate
group by esth1.IbesEstimateId, esth1.EstimateEndDate
I'd be grateful for any help, thanks.

hi all,
i have a doubt regarding a select operation performed on two tables with join statement.

table name- app_users

Now i want a grid which should show data like this
AppName LastDownloadedVersion Date_Downloaded
----------------------------------------------------------
TestV11 10 1/30/2007
SampleV5 -- ------
Here the value for appname should be created by appname+'V'+latest version of that appname(eg. Application name- Test Ltest version- 11 thus appname becomes 'TestV11')
Could anybody help me to solve this problem..
Thanx in advance..

I need to build an asp.net/C# application to read values from an Excel spreadsheet. Once the values are read from the spreadsheet, the C# code will do some elementary statistics on the values read. Then the values read and their computations will be written to a sql server database.
My manager suggested that SSIS might be a good candidate technology for doing this type of work. Does that sound correct? My only hesitation with using SSIS is that I want to keep the application as simple as possible, so that the code can be more portable. Maybe might argument is not a good one, but maybe someone can help me out here.

My environment:XP Home, VWD, SQLEXPRESS.A purely local setting, no network, no remote servers.
I try to do a JOIN query between tables in the membership ASPNETDB.mdf and one table in a self created 3L_Daten.mdf.
After dragging the tables into the Query Design window and connecting them VWD creates this query (here I added the control declaration):
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionStringAspNetDB %>" SelectCommand="SELECT aspnet_Users.UserName, aspnet_Membership.Password, aspnet_Membership.Email, aspnet_Membership.PasswordQuestion, aspnet_Membership.PasswordAnswer, aspnet_Membership.CreateDate, aspnet_Membership.LastLoginDate, aspnet_Roles.RoleName, [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.Age, [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.Sex, [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.Area FROM [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten INNER JOIN aspnet_Users ON [D:VISUAL STUDIO 2005WEBSITES3L_V1APP_DATA3L_DATEN.MDF].dbo.Personendaten.User_ID = aspnet_Users.UserId LEFT OUTER JOIN aspnet_Roles INNER JOIN aspnet_UsersInRoles ON aspnet_Roles.RoleId = aspnet_UsersInRoles.RoleId ON aspnet_Users.UserId = aspnet_UsersInRoles.UserId LEFT OUTER JOIN aspnet_Membership ON aspnet_Users.UserId = aspnet_Membership.UserId"></asp:SqlDataSource>
THIS WORKS, BUT:
As you can see the database 3L_Daten.mdf is inserted with its full path, which is not feasible for deployment reasons.
My question: How can I address both databases purely by their database names ? Both have been created within VWD and lie under App_Data.
(I tried almost everything, I practiced with the SQL Server 2005 Management Studio Express Edition, I tried linked servers, all without success).
Thank you for your consideration.
Here is the working query, shortened for the example:
SELECT a.SalesMan,a.CustomerName,b.Entry_Comments,b.Entry _Date

This works fine and I get all my detail reocrds for each master. Now I need
to be able to select only a single most recent b.Entry_Date. How can I do this, Ive played with MAX but cannot get the sytax correct?
Thanks,Adrian
In my new job I have to administer an existing SQL-database with approx. 50 tables. In this database are no joins :confused: defined between the tables. We use a Visual Basic 6 application to create a GUI and within this VB6 app. there are several SELECT statements to retrieve the required data. In these SELECT statements are all the INNER and OUTER JOINS between the tables defined.
My question: is this a correct way to work with or is it better to create all the JOINs between the tables on the database itself? Or should I create different views and define the JOINs in there? My main concern is the speed to retrieve data and second the required time to administer this database.

I realise I could remove the TopCategory from thestatement and that makes my DISTINCT work as I wanted, but Id prefer to havethe TopCategory as it saves me later having to another SQL query (Im alreadydoing one to allow me not to list category in the Statement .... but If Ican overcome this one ... then I can remove this as well).Here is my table structure (the necessary bits)productsidProduct int....categoriesidcategory intidParentCategory inttopcategory int...categories_productsidCatProd intidProduct intidCategoryWhen I run a query such asSELECT DISTINCT a.idProduct, a.description,a.descriptionLong,a.listPrice,a.price,a.smallImageUrl,a.stock, a.fileName,a.noShipCharge,c.topcategoryFROM products a, categories_products b, categories cWHERE active = -1 AND homePage = -1AND a.idProduct = b.idProductAND c.idcategory=b.idcategoryAND prodType = 1 ORDER BY a.idProduct DESCThis will return all products as expected, as well as any products which arein more than one TopCategory.Any ideas how to overcome this would be greatly appreciated.CheersCraig

Hi again,
I have this SQL (part of a stored procedure) where I do LEFT JOIN. SELECT callingPartyNumber, AlertingName, originalCalledPartyNumber, finalCalledPartyNumber,
dateTimeConnect,
dateTimeDisconnect,
CONVERT(char(8), DATEADD(second, duration, '0:00:00'), 108) AS duration,
clientMatterCode

LEFT JOIN CDR2.dbo.NumPlan t2 ON t1.callingPartyNumber=t2.DNorPattern
WHERE
(t1.callingPartyNumber LIKE ISNULL(@callingPartyNumber, t1.callingPartyNumber) + '%') AND
(t1.originalCalledPartyNumber LIKE ISNULL(@originalCalledPartyNumber, t1.originalCalledPartyNumber) + '%') AND
(t1.finalCalledPartyNumber LIKE ISNULL(@finalCalledPartyNumber, t1.finalCalledPartyNumber) + '%') AND
(t1.clientMatterCode LIKE ISNULL(@clientMatterCode, t1.clientMatterCode) + '%') AND
(@callerName is NULL OR t2.AlertingName LIKE '%' + @callerName + '%') AND
(t1.duration >= @theDuration) AND
((t1.datetimeConnect) >= ISNULL(convert(bigint,
datediff(ss, '01-01-1970 00:00:00', @dateTimeConnect)), t1.datetimeConnect)) AND
((t1.dateTimeDisconnect) <= ISNULL(convert(bigint,
datediff(ss, '01-01-1970 00:00:00', @dateTimeDisconnect)), t1.dateTimeDisconnect))
The problem is that if the t2 has more than one entry for the same DNorPattern, it pulls the record more than once. So say t1 has a callingPartyNumber = 1000. t2 has two records for this number. It will pull it more than once. How do I get the Unique value.
What I am trying to get is the AlertingName (name of the caller) field value from t2 based on DNorPattern (which is the phone number).
If this is not clear, please let me know.

select i.isbn, i.imageurl, i.author, i.title, i.publisher

I get the following error:
