how to update data using JOIN Conditions

My question is fairly simple. When I join between two tables, I always use the ON syntax. For example:
SELECT
*
FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId)
No problems there. However, if I then decide to further filter the selection based on some trait of the UserRole, I have two options: I can add the condition as a WHERE statement, or I can add the condition within the ON block.
--Version 1:
SELECT
*
FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId)
WHERE
UserRoles.Active = 'TRUE'
-- Version 2
SELECT
*
FROM
Users
JOIN UserRoles
ON (Users.UserRoleId = UserRoles.UserRoleId
AND UserRoles.Active = 'TRUE')
So, the question is, which is faster/better, if either? The Query Analyzer shows the two queries have the exact same execution plan, which makes sense, since they're both joining the same tables. However, I'm wondering if adding the condition in the ON statement results in fewer rows the JOIN statement initially needs to join up, thus reducing the overall initial size of the results table before the WHERE conditions are applied.
So is there a difference, performance wise? I imagine that if Users had a thousand records, and UserRoles had 10 records, then the JOIN would create a cartesian product of the two tables, resulting in 10,000 records in the table before the WHERE conditions are applied. However, if only three of the UserRoles is set to Active, would that mean that the resulting table, before applying WHERE conditions, would only contain 3000 records?
Thanks for whatever information you can provide.
pls:
1/ can we do it this way:
inner join Table2 ON table1.fld1=table2.fld21 AND table1.fld12=table2.fld22
2/also:
what s the difference between join , iner join and left join
Thanks .
Dear All,
I am not sure this is the correct forum for my issue, still im going on.....
I have a sql query which uses left outer join and where clause
select I.ir_id, I.ir_title,I. ir_b_type, I.ir_label, I.ir_createdby, I.ir_createdon, B.mstatus, B.bstatus from BR_IR I left outer join BR_BS Bon I.ir_id = B.bs_ir_id where I.ir_tr_rel = 'V03.03.06' order by I.ir_id desc
this works perfect. Now I want to exclude few records from the result on condn 'bstatus <> 'Yes'. So now my query will be
select I.ir_id, I.ir_title, I.ir_b_type, I.ir_label, I.ir_createdby, I.ir_createdon, B.mstatus, B.bstatus from BR_IR I left outer join BR_BS Bon I.ir_id = B.bs_ir_id where I.ir_tr_rel = 'V03.03.06' and B.bstatus <> 'Yes'order by I.ir_id desc
The below query will not return the left table records which doesnt have a matching one in the right table. It works something like inner join.
Could you please anyone tell me,where I am wrong?
Thanks,

I am using Transact-Sql 2005, and I'm trying to do a left outer join, including only certain accounts. The account number is x-xxx-xxxx-xxxx.
I want to include only accounts where the last 4 digits are > 7149, and the first 5 digits are between 2-110 and 2-999, or are equal to 8-001.
This is my code, based on 2 temporary tables I have previously populated:
select
b.gl7accountsid,
b.accountnumber,
t.description,
t.category,
t.postdate,
t.poststatus,
t.transactiontype,
t.transamount,
coalesce(t.transamount,0) as TransactionAmount,
t.encumbrancestatus,
t.gl7fiscalperiodsid,
b.budamount,
b.gl7budgetscenariosid
from
#budgets b
left outer
join
#transactions t
on t.accountnumber=b.accountnumber
And right(t.accountnumber,4) > 7149
and (left(t.accountnumber,5) between '2-110' and '2-999' or left(t.accountnumber,5)='8-001')
order by b.accountnumber
I keep getting accounts with the last 4 digits > 7149, and also accounts whose numbers don't fall into the desired group of the first 5 digits.
I'm fairly new to SQL, and I'm thinking there must be a way to do what I want to do, but I don't know what it is.
Can anyone help?
Thanks very much ,

Hi Faculties,I have two queries which give me the same output.-- Query 1SELECT prod.name, cat.nameFROM products prod INNER JOIN categories catON prod.category_id = cat.idWHERE cat.id = 1;-- Query 2SELECT prod.name, cat.nameFROM products prod INNER JOIN categories catON prod.category_id = cat.id AND cat.id = 1;The first query uses the WHERE clause and the second one has all theconditions in the ON clause. Is there anthing wrong with the secondapproach in terms of performance? Please suggest.Thanks in advanceJackal
View 6 Replies View RelatedI have a SELECT Statement that I am using that is pulling from two tables. There won't always be results in the second table so I made a LEFT OUTER JOIN. The problem I am having is that I need to have three conditions in there:WHERE (employee.emp_id = @emp_id) AND (request.requested_time_taken = 'FALSE') AND (request.request_end_date >= GETDATE()))The two conditions from the request table are causing the entire query to return NULL as the value. I need help trying get a value whether or not there are any results in the request table.Here is the full select statement:SELECT (SELECT SUM(ISNULL(request.request_duration, '0')) AS Expr1

request AS request ON employee.emp_id = request.emp_id
WHERE (employee.emp_id = @emp_id) AND (request.requested_time_taken = 'FALSE') AND (request.request_end_date >= GETDATE()))

Select

ISNULL(r.dbStatusDesc, 'No Ref') AS dbStatusDesc,
ISNULL(t.dbSchTypeCode, 'No Ref') AS dbSchTypeCode,
ISNULL(t.dbSchTypeDesc, 'No Ref') AS dbSchTypeDesc,
[code]....
however, I only want the lastest a.dbPatApptTime and only when a.dbPFStatus = 1 and a.ClientRef = 'EPS'
So the stand alone sql could be....
Select Top(1) dbPatApptTime as LastVisitDate, dbSchTypeDesc as LastVisitDesc
from appointments
where dbPFStatus = 1 and clientref = 'EPS'
order by dbPatApptTime desc
I'm just not sure how to incorporate that into my sql or whether there is a better way,

I need to update the status of a client when they make a payment of a certine amount. My problem is this, the two pieces of information needed to do this are comming from two tables. For example;
@ClientID Int,
@PmtAmt Money
IF @PmtAmt >= tblSettings.TopAmt THEN
Update tblClients
SET
ClientStatus='High'
WHERE ClientID=@ClientID
ELSE
Update tblClients
SET
ClientStatus='Medium'
WHERE ClientID=@ClientID
ENDIF
How do I do this in a stored procedure? I need to select the TopAmt from the table tblSettings and then update the table tblClients.

I have a table (GLTRANS) with thousands of lines.
1 column in the table (ACCNO) has 300 different values which all need to change to a new value.
ie. 11100 all change to 8100
11200 all change to 8200
I know how to do a simple UPDATE
UPDATE GLTRANS
SET ACCNO = '8100'
WHERE ACCNO = '11100'
But how can i combine into 1 script rather than having to continually change this script 300 times??

In the last weeks I came to work with SQL Server more closely and - not being used to it - I stumbled over the sematics of an UPDATE statement using a JOIN (something which is not available in e.g. Oracle).I wonder what the difference between these two updates is:
Code:
update foo
set ..
from bar
where bar.fid = foo.id;
and
Code:
update foo
set ...
from foo f1
join bar on bar.fid = f1.id;
In both cases I have an inner join between foo and bar, but in the second one, foo is actually listed twice in the update statement. As far as I can tell, both carry out the same thing - at least with my test data.
Best Greetings,
i want to make an update query for a table but the where clause will check a join with other talbe

I have a customers CRM DB that I need to run an update query on, affecting around 14,000 records. The fields used in the entity in question are split across two tables. I need to update a field in one tabled based off of the result of a field in the other table.
So this is what I started with:
USE db1
UPDATE tbl2 SET field1 = '1' WHERE tbl1.CreatedOn < '2013-28-09 00:00:00.000';
This didn't work, SQL complained about being unable to bind tbl1.CreatedOn. I assume because it's in a different table to the one I'm updating.
I attempted a JOIN to the best of my limited SQL knowledge, thinking I could just shove the two tables together and it might be happy.
USE db1
INNER JOIN tbl1 ON tbl2.Id=tbl1.Id;
UPDATE tbl2 SET field1 = '1' WHERE tbl1.CreatedOn < '2013-28-09 00:00:00.000';
This also didn't work, complaining of syntax error near 'INNER'
I'm obviously missing something, but IU don't know what it is.
I have a table with date values that are currently null.
I've created a query that identifies the dates that should go into the date field for the table. I'll call the table "shipping" and the SQL Query, "query".
query has the following fields:
CN int
CSN int
shipdate datetime
shipping has the following fields that are relavent:
CN int
CSN int
shipped_date datetime
I want to update shipping, setting shipping.shipped_date=query.shipdate
where query.cn=shipping.cn and query.csn=shipping.csn
How do I word it to get a proper update using query analyzer?
