Getting Unique Rows From Multi-table Query
Mar 10, 2012how to join these 3 tables but there are duplicate rows in the results. How can I get all the unique rows to only show up once.
My query is:
SELECT tbl_rate.rate_ID, tbl_rate.rate_site_IDref, tbl_rate.rate_rank_IDref, tbl_rate.rate_dollar, tbl_rate.rate_ot, tbl_rate.rate_dt, tbl_rate.rate_loa,
tbl_employee.employee_name, tbl_LEM.LEM_date, tbl_LEM.LEM_reg_hrs, tbl_LEM.LEM_ot_hrs, tbl_LEM.LEM_dt_hrs, tbl_LEM.LEM_tt_hrs, tbl_LEM.site_IDREF,
tbl_LEM.LEM_LOA, tbl_LEM.LEM_Expenseinfo, tbl_LEM.LEM_workorder, tbl_LEM.LEM_posted, tbl_LEM.LEM_Expense, tbl_LEM.LEM_tagnumberREF,
tbl_LEM.LEM_reg_rate, tbl_LEM.Lem_ot_rate, tbl_LEM.Lem_tt_rate, tbl_LEM.LEM_dt_rate, tbl_LEM.Lem_loa_rate, tbl_LEM.LEM_ID, tbl_LEM.LEM_equip_days
FROM tbl_rate INNER JOIN
tbl_employee ON tbl_rate.rate_rank_IDref = tbl_employee.employee_rankREF INNER JOIN
tbl_LEM ON tbl_employee.employee_ID = tbl_LEM.employee_IDREF
The results somehow need to be distinct by tbl_lems.lem_ID
Query On Multiple Rows In Single Table?

Combine 2 Rows From Derived Table Into 1 Row W/o Repeating Query?
Aug 1, 2007I'm trying not to use a temp table, but i may have to do so..
I'm using sql2005 for this case.
i have a derived table that makes the following results:
ID Status Name
2 1 "A"
2 2 "B"
I want to get the following:
ID Name1 Name2
2 "A" "B"
but like I said before, I can't repeat the query that gets the first 2 rows, as it's pretty invovled. a temp table is the best route I see right now, but I just wanted to be sure I'm not missing something. If I've aliased it as 'results', is there a way to alias results again as something else? or maybe a trick with CTEs? I will try that! It seems promising.
Table Imported From Excel - Query For Columns Into Rows

Color Red Size 4 Height 2inch NULL NULL NULL NULL
Color Red Size 5 Height 2inch NULL NULL Length 1 cm
Color Red Size 4 Height 3inch NULL NULL NULL
Color Black Size 6 Height 1inch NULL NULL NULL NULL
I need the output as
Var --- Val
Color --- Red,Black
Size --- 4,5,6
Height 1inch,2inch,3inch
Length 1 cm
Var or val can be either NULL or white space. I cannot use a function.
SQL Query History Table To Return Only Active Rows
Mar 5, 2008
Given the following data how do I make a SQL query that returns only 1 row per product?
The returned rows need consist of only currently active products (that is WHERE (DateEffective <= { fn NOW() }).
The twist: Sometimes a product will have duplicate DateEffective records. In that case, only return the record created latest because that's the most current data that exists for a product. RowTimeStap is when the record was created.
Example Data:
HistoryID ProductID Name Color DateEffective RowTimeStamp
(auto-number PK)
1 1 Wheel Red 2/1/2008 2/1/2008
2 1 Wheel Blue 3/5/2008 3/1/2008
3 1 Wheel Orange 3/5/2008 3/2/2008
4 1 Wheel Black 1/1/2010 3/3/2008
5 2 Knob Blue 3/2/2008 3/2/2008
6 2 Knob Green 3/3/2008 3/3/2008
Query should return:
3 1 Wheel Orange 3/5/2008 3/2/2008
5 2 Knob Green 3/3/2008 3/3/2008
The query I've created fails on the twist part. I have to allow duplicate DateEffective to keep a history of changes.
Can anyone help?

Transact SQL :: Query To Update A Table With More Than 150 Million Rows Of Data?
Sep 17, 2015I have been tasked with writing an update query to update a table with more than 150 million rows of data. Here are the table structures:
Source Tables :
OC
CREATE TABLE [dbo].[OC](
[OC] [nvarchar](255) NULL,
[DATE DEBUT] [date] NULL,
[DATE FIN] [date] NULL,
[Code Article] [nvarchar](255) NULL,
[INSERTION] [nvarchar](255) NULL,
[Code] ....
The update requirement is as follows:
DECLARE @Counter INT=0 --This causes the @@rowcount to be > 0
while @@rowcount>0
BEGIN
SET rowcount 10000
update r
set Comp=t.Comp

The update took more than 48h and didn't terminate , how to accelerate it ?

Nov 8, 2007Hi All,
I am using sql server 2005. I stuck out in a strange problem.
I am using view in my stored procedure, when I run the stored procedure some of the rows get skipped out means if select query have to return 10 rows then it is returning 5 rows or any other but not all, also the records displyaing is randomly coming, some time it is displaying reords 12345 next time 5678, other time 2468.
But if I run seperately the querys written in SP then it returns all the rows. Please give me solution why it is happening like this.
There are indexes in the tables.
Once I shrink the database and rebuild the indexes, from then this problem is happening. I have rebuild the indexes several time, also updated the statistics but nothing improving.
But nothing is improving

SP To Perform Query Based On Multiple Rows From Another Query's Result Set
Nov 7, 2007I have two tables .. in one (containing user data, lets call it u).The important fields are:u.userName, u.userID (uniqueidentifier) and u.workgroupID (uniqueidentifier)The second table (w) has fieldsw.delegateID (uniqueidentifier), w.workgroupID (uniqueidentifier) The SP takes the delegateID and I want to gather all the people from table u where any of the workgroupID's for that delegate match in w. one delegateID may be tied to multiple workgroupID's. I know I can create a temporary table (@wgs) and do a: INSERT INTO @wgs SELECT workgroupID from w WHERE delegateID = @delegateIDthat creates a result set with all the workgroupID's .. this may be one, none or multipleI then want to get all u.userName, u.userID FROM u WHERE u.workgroupIDThis query works on an individual workgroupID (using another temp table, @users to aggregate the results was my thought, so that's included) INSERT INTO @users SELECT u.userName,u.userID FROM tableU u LEFT JOIN tableW w ON w.workgroupID = u.workgroupID WHERE u.workgroupID = @workGroupIDI'm trying to avoid looping or using a CURSOR for the performance hit (had to kick the development server after one of the cursor attempts yesterday)Essentially what I'm after is: SELECT u.userName,u.userID
FROM tableU u
LEFT JOIN tableW w ON w.workgroupID = u.workgroupID
WHERE u.workgroupID = (SELECT workgroupID from w WHERE delegateID = @delegateID) ... but that syntax does not work and I haven't found another work around yet.TIA!

Delete Rows In One Table By Referencing Another Table Info
Sep 16, 2004I have one table that has unique id's associated with each row of information. I want to delete rows of information in one table that have a unique ID that references information in another table.
Here is a basic breakdown of what I am trying to do:
Table1 (the table where the rows need to be deleted from)
Column_x (Holds the id that is unique to the various rows of data - User ID)
Table2 (Holds the user information & has the associated ID)
Column_z (holds the User ID)
I tried this on a test set of tables and could not get it to work. What I am trying to do is skip all rows of Table1 that have ID's present in Table2, and delete the rows of ID's that are not present in Table2.
Code:
SELECT Column_z
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z <> Column_x
This did not seem to do what I needed, it did not delete any rows at all.
I wanted it to delete all rows in Table1 that did not have a reference to a user ID that matched any ID's in Column_z of Table2
Then I tried another scenerio that I also needed to do:
Code:
SELECT Column_z, Column_a
FROM dbo.Table2
DELETE FROM dbo.Table1
WHERE Column_z = Column_x AND Column_a='0'
'0' being the user id is inactive so I wanted to delete rows in Table1 and remove all references to users that were in an inactive status in Table2.
Neither one of the Queries wanted to work for me in the Query Analyzer when I ran them. It just said (0) rows affected.
Any ideas on what I am doing wrong here?

Table Scans - More Rows Brought Back Than In Table
Jul 20, 2005I have a query which is quite complex. It's based on a set of data ina complex view which takes the data from several tables.In this complex query, if I allow the various parts of the query towork on the results of the view (MISView), it can take 15 minutes torun (eek !), however, if I create a temporary table with the data fromthe view and then use that for the remainder of the query, it runs inapprox 20 seconds.Now, I have examined the execution plan (my new favourite toy) andthere is a difference (as expected). However when looking at the partof the query that takes up most of the time, it shows that it bringsback 109,645,866 records from a table (Credit) that contains 13,002records. This table is one that is referenced in the view (MISView)which contains 13,653 records and does get some of it's data from thetable which is scanned (Credit).For the record, we don't have any tables with over 100,000 records in,so 109 million rows is going some for us. The part of the query thatruns slow does reference another copy of itself but this is necessaryfor the equation that is being run.Now I'm OK with why it's doing the table scan, but why does it bringback substantially more data than is in the table ? Is it somemultiple of the number of records that it's trying to work out. Iassume it tries to run a seperate plan for the view as part of it'sprocess.Ideally, I'm still going to go down the route of the temporary table,but I would like to understand more about what it does first as Idon't like leaving things unanswered.Any help would be appreciated.
View 6 Replies View RelatedHow To Insert Rows To Table B Based On Values In Table A.

I need Insert rows in the OrderDetails Table based on values in the Orders Table
In the Orders table i have a columns called OrderID and ISale.
In the OrdersDetails i have columns called OrderID and SaleType
For each value in the OrderID Column of the Orders Table, anytime the ISale Column in the Orders table = 1, and the SalesType column in the OrderDetails table is empty, I want to add two rows in the OrderDetails table. One row with the value K and another row with the value KD.
That is a row will be added and the value in the SalesType column will be K, also a second row will be added and the value in the SalesType column will be KD
Also for each value in the OrderID Column of the Orders Table, anytime the ISale Column in the Orders table = 0, and the SalesType column in the OrderDetails table is empty, I want to add two rows in the OrderDetails table. One row with the value Q and another row with the value QD
That is a row will be added and the value in the SalesType column will be Q, also a second row will be added and the value in the SalesType column will be QD.
I need a SQL Script to accomplish this. thanks
