Selecting Multiple Column From Sub Query.
Apr 17, 2008
Hi,
I am having two tables Products and Transaction
In products I have ProductID and Description. (10 Records)
In Transaction I have ProductID, Lot, Quantity and ListID . ( 4 Million Records)
When I use the inner join between these tables as below query its taking lot of time to give output.
select ProductID, Desc, Lot, qty from Products inner join Transactions on Products.ProductID = Transactions.ProductID
where ListID = '9090909'
otherwise, if I use the below query its takes very few milli seconds to give output but I am not able to get the description from the product table.
select * from Transactions TR where TR.ListID= '9090909' and TR.ProductID in
(select NDC from Products where Products.ProductID = TR.ProductID)
Any from can help me to get the description too at very few times.
Regards,

I have a SQL Query issue you can find in SQL Fiddle
SQL FIDDLE for Demo
My query was like this
For Insert
Insert into Employee values('aa', 'T', 'qqq')
Insert into Employee values('aa' , 'F' , 'qqq')
Insert into Employee values('bb', 'F' , 'eee')
Insert into Employee values('cc' , 'T' , 'rrr')
Insert into Employee values('cc' , 'pp' , 'aaa')
Insert into Employee values('cc' , 'Zz' , 'bab')
Insert into Employee values('cc' , 'ZZ' , 'bac')
For select
select col1,MAX(col2) as Col2,Max(Col3) as Col3
from Employee
group by Col1
I supposed to get last row as
cc Zz bab
Instead I am getting
cc Zz rrr
which is wrong

Hello,
Is it possible to get a list of rows from Multiple tables which have the same Column Name. I have 3 tables which comtain similar info
and I want to get a list of Names
the structure is
ID;Name;Address;Phone No.
I was thinking something along the lines of SELECT Name FROM TABLE1,TABLE2, TABLE3
But this does not work.
Is there a nice way of doing this with SQL or should I do code outside the SQL DB

Hey all,I am having some serious trouble getting the correct syntax for a select statement to work the way I need it, any help I could get on this would be greatly appreciated.I have a table called Units which stores computers and a table called Software which stores software. I have a bit field in Units called OEM, when this is set to true I don't want the select statement to pull this unit down when I am assigning software to other units.Here is my select statement: SELECT Software.SID, Software.SN, Software.Name, Users.First + ' ' + Users.Last AS 'Assigned User', Units.Make + '-' + Units.Model AS 'Assigned Unit' FROM dbo.Software LEFT JOIN dbo.Units ON Software.SN = Units.SN LEFT JOIN dbo.Users ON Units.UID = Users.UID WHERE (Units.OEM = 'FALSE') AND (Software.SN LIKE '%' + @SearchString + '%')Everything works as expected, unless of course the unit has no software assigned to it yet, it won't return it because its not tied to a Units.OEM field. Is there anyway to have it return ALL records that even arn't joined OR are joined but have OEM set to false?Thanks, let me know if I need to clear anything up.-Matthew

Hello all. I hope someone can offer me some help. I'm trying to construct a SQL statement that will be run on a Dataset that I have. The trick is that there are many conditions that can apply. I'll describe my situation:
I have about 1700 records in a datatable titled "AISC_Shapes_Table" with 49 columns. What I would like to do is allow the user of my VB application to 'create' a custom query (i.e. advanced search). For now, I'll just discuss two columns; The Section Label titled "AISC_MANUAL_LABEL" and the Weight column "W". The data appears in the following manner:
(AISC_Shapes_Table)
AISC_MANUAL_LABEL W
W44x300 300
W42x200 200
(and so on)
WT22x150 150
WT21x100 100
(and so on)
MT12.5x12.4 12.4
MT12x10 10
(etc.)
I have a listbox which users can select MULTIPLE "Manual Labels" or shapes. They then select a property (W for weight, in this case) and a limitation (greater than a value, less than a value, or between two values). From all this, I create a custom Query string or filter to apply to my BindingSource.Filter method. However I have to use the % wildcard to deal with exceptions. If the user only wants W shapes, I use "...LIKE 'W%'" and "...NOT LIKE 'WT%" to be sure to select ONLY W shapes and no WT's. The problems arises, however, when the user wants multiple shapes in general. If I want to select all the "AISC_MANUAL_LABEL" values with W <= 40, I can't do it. An example of a statement I tried to use to select WT% Labels and MT% labels with weight (W)<=100 is:
Code SnippetSELECT AISC_MANUAL_LABEL, W
FROM AISC_Shape_Table
WHERE (W <= 100) AND ((AISC_MANUAL_LABEL LIKE 'MT%') AND (AISC_MANUAL_LABEL LIKE 'WT%'))
It returns a NULL value to me, which i know is NOT because no such values exist. So, I further investigated and tried to use a subquery seeing if IN, ANY, or ALL would work, but to no avail. Can anyone offer up any suggestions? I know that if I can get an example of ONE of them to work, then I'll easily be able to apply it to all of my cases. Otherwise, am I just going about this the hard way or is it even possible? Please, ANY suggestions will help. Thank you in advance.
Regards,
Steve G.

What I need is the start and end time of each task, but the issue is there is no unique task number to bind them together.. So for instance the task starts with 'Open-Submitted' and ends with 'Task Approved'. The issue is there can be multiple occurrences in the same file number. I need to be able to split these into multiple tasks with the associated start and stop times.

Hi there,I'm new to sql and thus I'm having problems with a specific query which Ihope you guys can help me with.Basicly I have a few tables which I'm trying to do a query on:Table groups contains information about specific groups e.g. "Windows" or"Unix".Table users contains information about specific users e.g. "a", "b" or "c".Table users_groups contain information about group relationship (a user canbe in multiple groups) e.g. (a, Windows), (b, Unix), (a, Unix).In this case user c is ungrouped.Now I'd like to find the users which does belong to group Windows and thosewho do not:select distinct username from users_groups where groupname = "Windows" orderby username asc;This works pretty well for finding users in the specific group. In this casethe result is a.However I'd like to get the opposite result (b and c) but I'm stuck.The problem is that I'd like a list of all users excluding those which arein "Windows"Here is a partial query:select distinct users.username from users left join users_groups onusers.username = users_groups.username where users_groups.username is nullorder by users.username asc;This only gives me those users who are not grouped at all. This mean thatuser b is not in those results.Please advise.Thanks in advance.-- Henrik

I have data like the following:
ID COUNTER DATA
1 10 BLAH
1 20 BLAH
2 10 BLAH
3 10 BLAH
2 20 BLAH
2 30 BLAH
What I want to return is:
1 20 BLAH
2 30 BLAH
3 10 BLAH
I want the top 1, having the highest counter from each ID. This is a highly simplified version of that I am pulling which also is between a date range, but same principle.
IE: SELECT * FROM Table WHERE ID in (SELECT DISTINCT ID FROM Table WHERE Date BETWEEN <date> AND <date>
I'd rather keep it in one statement if possible, but if I have to do it in multiple passes then so be it.

Your help is greatly appreciated. How do you query each one of the following:
1) SELECT FieldValue WHERE DateTime is from 8:30AM - 12:00PM and 6:00PM - 9:30PM on Mondays thru Fridays (i.e. exclude Sat & Sun) for the whole month of January 2008.
2) SELECT FieldValue WHERE DateTime is from 9:30PM - 8:30AM on Mondays thru Fridays, AND ALL-DAY on Saturdays & Sundays for the whole month of January 2008.
Thank you in advance.

Hi
I have a gridview with a sql data source and a few drop down lists where i choose values to sorth what i would like to retrive from the table. The problem im facing is that when i pass values to the database, i can sort out and retrive my items when both my listboxes have selected values.
But when i want to select everything from the table where the column = clumn or cloumn = value i dont get anything back.
I have 2 dropdown lists. One for category and one for location. These are populated drom the database by selecting the column and retriving destinct values. I have a function that fires when one of the dropdown lists are changed witch changes the sql datasource select value so it retrives items sorted by the selected categories and locations.
Here is the function:
protected void DropDownList_Change(object sender, EventArgs e) { string Category = DropDownListKategori.SelectedValue.ToString(); string Location = DropDownListEtabl.SelectedValue.ToString(); SqlDataSource1.SelectCommand = "SELECT ARTNR, ARTTYP, AKTIVITET, DATUM, KUND, PLATS, KOMMENTAR FROM ARTIKEL WHERE ARTTYP = @ARTTYP AND PLATS = @PLATS"; SqlDataSource1.SelectParameters.Clear(); SqlDataSource1.SelectParameters.Add(@"ARTTYP", Category); SqlDataSource1.SelectParameters.Add(@"PLATS", Location); SqlDataSource1.DataBind(); }
The dropdown lists have an option to not retrive values by category or location. I have set that value to PLATS and ARTTYP thinking the query would would retrive everything if these were selected
SELECT ARTNR, ARTTYP, AKTIVITET, DATUM, KUND, PLATS, KOMMENTAR FROM ARTIKEL WHERE ARTTYP = ARTTYP AND PLATS = PLATS
however if both these drop down lists are set to not filter, my query gets nothing in return. And if one of the lists has this selected and ther other one has a value, say a location or something nothing is retrived either. However if both columns have something selected i do get values returned.
My speculation is that the query beeing run when this happens is that it is trying to find columns having the value ARTTYP or PLATS (category or location), as a string and actually seeing it as Im trying to retrive values where column = column.
Any suggestions on how i can make my query run as intended or is there another problem Im not seeing.

I have inherited a query which currently returns multiple instances of each work order because of the joined tables. The code is here and I've detailed the criteria needed below but need the best way to accomplish this:
Select h.worknumber, h.itemcode, h.descr, h.task_descr, h.qty, h.itemised,
h.serialnum, h.manufacturer, h.model_id, h.depot, h.date_in, h.date_approved,
h.est_complete_date, h.actual_complete_date, h.meterstart, h.meterstop,
h.custnum, h.name cust_name, h.addr1, h.addr2, h.town, h.county, h.postcode,
h.country_id, h.contact, h.sitename, h.siteaddr1, h.siteaddr2, h.sitetown,
[Code] ....
Each work order should only be returned once, and with the following additional criteria:
1. i.meter - this should return only the lowest number from that file.
2. sm.next_calendar_date - this should return only the most recent date out of those selected for the certificates on this piece of equipment
3. wh.meterstop as [Last Service Hours],
wh.date_created as [Last Service] - this should return the number from wh.meterstop at the most recent wh.date_created for that piece of equipment.

Hi
I currently have two tables called Book and JournalPaper, both of which have a column called Publisher. Currently the data in the Publisher column is the Publisher name that is entered straight into either table and has been duplicated in many cases. To tidy this up I have created a new table called Publisher where each entry will have a unique ID.
I now want to remove the Publisher columns from Book and JournalPaper, replace it with an ID foreign key column and move the Publisher name data into the Publisher table. Is there a way I can do this without duplicating the data as some publishers appear several times on both tables?
Any help with this will be greatly appreciated as my limited SQL is not up to this particular challenge!!!
Thanks!

Hi All,I'm trying to solve this for a few days now and I just can't figure itout...I have three tables set up, I'll simplify them for this question:Table 1: HOTELSColumns: HOTEL_ID, HOTEL_NAMEExmple row: 123 || 'Hotel X'Table 2: SERVICESColumns: SERVICE_ID, SERVICE_NAMEExample rows:1 || 'Breakfast in bed'2 || 'King size bed'Table 3: LINK_HOTELS_SERVICESColumns: FK_HOTEL_ID, FK_SERVICE_ID, SERVICE_VALUEExample rows:123 || 1 || 1123 || 2 || 1In table 3 I link different services to different hotels. In the same tableI set the "value" for the service.The first example row of table 3 means something like: Hotel X offersBreakfast in bed. In this case 1 stands for TRUEThe second example row of table 3 means: Hotel X offers King size beds(again: 1 stands for TRUE).What I'm struggling with is selecting the hotel ID's which offer multipleservices. To stay in the example: how can I select all hotels whereSERVICE_ID = 1 AND SERVICE_ID = 1. I can't seem to figure out how to doit...I hope anyone can help... Thanks a lot in advance!!!Robert

I want to have a linking table say for example we call this a claim. Based on the claim number you need to relate to one of say 6 different types of claims. The types of claims related to their own individual parent table. (individual because each type of claim tracks completely different information) does anyone have an idea on how to set this up?
Sample Structure
table = Claim
Field 1 = ClaimTypeA_ID
Field 2 = ClaimTypeB_ID
Field 3 = ClaimTypeC_ID
Field 4 = ClaimTypeD_ID
Field 5 = ClaimTypeE_ID
Field 6 = ClaimTypeF_ID
The six field relate to the 6 different tables ID.
If I do this how do I store the data? put 0's in each of the claim types that are not used???
Any suggestions would be appreciated.

I need to list all the records in Table2 which don't have matching field values in Table1.
This the the exact opposite of what I need:
SELECT DISTINCT
Field1,
Field2,
Field3,
Field4,
Field5
FROM
[Table1]
WHERE EXISTS(
SELECT DISTINCT
FieldA,
FieldB,
FieldC,
FieldD,
FieldE
FROM
[Table2]
)
The above seems to give me all records in Table1 in which the five fields match the five fields specified in Table2. What does not show up is the test record I put in Table2 which is not in Table1.
What I need, however, is the exact opposite.
I tried the above using NOT EXISTS but I get no records at all.
How do do this?

I have a SSRS report with a Parameter that lets you choose the name of an employee. The report lists their Name, Number, User ID etc.
When you select a single employee, the filter on the Dataset works perfectly. However once you select two or more employee names, it only returns the first result.
The parameter, Field, and Filter are text.
The Filter is EmployeeName IN @EmployeeName

I'm trying to determine the oldest timestamp that meets given criteria which includes a specific action_type code. That code can legitimately be performed more than once on an item (all actions are recorded in an actions table, so the full history is available).
actions table (columns: action_id, request_id, action_type, action_time, action_reason)
I'm having trouble getting the most recent timestamp for the given action_type I'm looking for, when that action_type has been performed more than once.
My intent with the query below is to get the most recent action_time and it's request_id that meets the criteria
SELECT TOP 1 a.action_time, r.request_id FROM requests r JOIN incident i ON r.request_id = i.request_id LEFT JOIN actions a ON r.request_id = a.request_id WHERE i.refund_type = 1 AND (r.status_code = 3 OR r.status_code = 14) AND a.action_type = 3 ORDER BY a.action_time
So for example, if the item with request_id 1334 has had action_type 3 performed on it twice, once at 2007-10-15 13:30:00 and then again at 2007-10-17 14:40:00, it's picking up the former, when I want the later. That it had action_type 3 performed on it twice is legitimate. (larger context an item was approved by a manager, then rejected by a processor, and then approved by a manager again after resubmission)
Hopefully this has made sense so far.
So, how do I make sure I'm getting the most recent action time, when I don't know if the item in particular will have more than one of this action type performed on it?
