Calculating Percentages Based On Multiple Rows

Oct 2, 2014

I have two tables that look like this (below). One tells me the name of my product, the Amazon Category it is in & the amount that I want to sell it for. The other tells me the Category & the fee for that category. So far so good. Though it gets tricky in the sense that some categories have two tiers. So in Electronics, the fee for $0.00 - $100.00 is 15%. But from $100 and up it is 8%.

Since it has two columns & both of the new columns pertain to the fee of my product, I can't figure out how to use both at once. For my $599.99 example it would be ($100 * 0.15) + ($499.99 * 0.08) = $55.00. Would I pivot the data? If not, how would I group it to be considered together?

Category Example

IDAmazonCategoryIDAmazonCategoryNameFeePercentageStartPriceEndPrice

1apsAllDepartments0.150.000.00
2instant-videoAmazonInstantVideo0.000.000.00
3appliancesAppliances0.150.000.00

Product Example

1Product1Electronics9.99
2Product3Electronics99.99
3Product2Electronics599.99

Raw SQL
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE #Amzn_Category_FeeStructure(
[ID] [int] IDENTITY(1,1) NOT NULL,

[Code] ....

I use Microsoft SQL 2008

Calculating Percentages For Each Row

Dec 10, 2007

One more for you while I'm trying to remember my SQL skill from a few years ago (last one of the day - promise):
My database looks like:

(Ignore that the ERD is in Access, the database is SQL Server 2005)

How do I calculate sales percentages?
I.E. how do I calculate the percentage that each product has sold as a percentage of the total sales?

What I'm aiming for is each row of products is shown, with its percentage of the whole sales.

AVG is involved this time, isn't it?

The productID is of the int datatype (not that you need to know that field - but never mind) and the quantity is a smallint, before you ask


Thank you in advance for any replies.

Calculating Percentages And Showing In Separate Columns

Aug 31, 2013

SELECT DISTINCT CASE WHEN SM.SERVICE_TYPE_N = 1 THEN 'LABORATORY'
WHEN SM.SERVICE_TYPE_N = 2 THEN 'PODIATRY'
WHEN SM.SERVICE_TYPE_N = 3 THEN 'ADMINISTRATION'
WHEN SM.SERVICE_TYPE_N = 4 THEN 'DIET'
WHEN SM.SERVICE_TYPE_N = 5 THEN 'DENTAL'

[Code] ....

In the above query i need to calculate 100%,30% and percentage other than 100 and 30 and show them in separate columns how to do that?

1)ROUND(SUM(BM.CONCESSION_AMOUNT_M),2)AS [100_PERCENT]
WHERE BM.BILL_AMOUNT_M=BM.CONCESSION_AMOUNT_M

2)ROUND(SUM(BM.CONCESSION_AMOUNT_M),2)AS [30_PERCENT]
WHERE AND BM.CONCESSION_AMOUNT_M=BM.BILL_AMOUNT_M * 0.30

3) ROUND(SUM(BM.CONCESSION_AMOUNT_M),2)AS [OTHER_CONCESSION_PERCENT]
WHERE BM.CONCESSION_AMOUNT_M between BM.BILL_AMOUNT_M*0.001 and BM.BILL_AMOUNT_M*0.299
OR BM.CONCESSION_AMOUNT_M between BM.BILL_AMOUNT_M*0.301 and BM.BILL_AMOUNT_M*0.999

Combining Multiple Rows Based Off Criteria

Mar 21, 2006

Hello again,

Another combining multiple rows teaser, during a few routines I made a mistake and I would like to combine my efforts. Here is my data:


Code:


Table A

ID DSN VN AX Diag
1111296.54
3212318.00



Both DSNs share the same Patient_id in a seperate table which holds the DSN numbers and their corresponding patients.


Code:


Table B

DSN Patient_id
100000001
200000001



So what I need to do is maintain their unique 'ID' number in Table A but update their DSN numbers to reflect the first instance in Table B. So my data would look like this in both tables.


Code:


Table A

ID DSN VN AX Diag
1111296.54
3112318.00

Note: The second rows DSN changed to 1 from 2




Code:


Table B

DSN Patient_id
100000001
(Duplicate row removed with same patient_id)



The result would look like the above but as you noticed I need to remove the duplicate row that had the different DSN in Table B so that only one DSN remains that can map to multiple rows (IDs) in Table A.

Table A:

DSN can map to multiple rows (IDs)
IDs must be unique (aka kept to what they are currently)

Table B:

Second row with same DSN must be removed.

Any takes, ideas? I need to do this on a couple thousand rows....

Thanks, and im happy to clarify if needed.

Multiple Rows Combined Based On A Column

Sep 6, 2011

I have a table with two columns refid and name and it has the following values

1 tom
1 jim
2 bob
1 bob

I need a resultset that would have the following values

1 tom, jim, bob
2 bob

I have tried couple of things one being:

DECLARE @namelist VARCHAR(1000)
SELECT @namelist = COALESCE(@namelist +', ' ,'') + name FROM sales where refid = 1
SELECT @namelist

But I am looking for a resultset with a unique refid and all the names comma separated for that refid.

Updating Multiple Rows Based On Sums From Another Table

Apr 12, 2007

Hello All

I am trying to figure out if what i am attempting to do is possible and whether or not my approach is wrong to begin with.

I am trying to build a custom report for our accounting system which is Traverse from Open systems. This is what i have done in the stored procedure thus far


SET QUOTED_IDENTIFIER ON
GO
SET ANSI_NULLS ON
GO

ALTER PROCEDURE rptArFLSalesByCustItemized_sp
@custId pCustID,
@dateFrom datetime,
@dateThru datetime,
@itemIdFrom pItemId,

as
set nocount on

-- define some variables for previous year
declare @LYqty int, @LyAmt money, @LYfrom datetime, @LYthru datetime

-- set defaults
SET @itemIdFrom=ISNULL(@itemIdFrom,(SELECT MIN(itemId) FROM tblInItem))
SET @itemIdThru=ISNULL(@itemIdThru,(SELECT MAX(itemId) FROM tblInItem))
SET @LYfrom=DATEADD(YEAR,-1,@dateFrom)
SET @LYthru=DATEADD(YEAR, -1, @dateThru)

-- create small temp table to hold customer info
Create Table #tmpArCustInfo
(
custId pCustID,
custName VARCHAR (30),
)
-- populate customer temp table with info
Insert into #tmpArCustInfo
select custId, custName
from tblArCust
WHERE custId = @custId


-- create a temp table to hold the Data for each Item
Create Table #tmpArSalesItemized
(
itemId pItemId,
productLine VARCHAR (12),
pLineDesc VARCHAR (35),
descr VARCHAR (35),
LYQtySold int,
LYTDQtySold int,
QtySold int,
LYTDsales money,
totalSales money,
LastInvDate datetime,
)

-- populate the temp table with all of the inventory items
insert into #tmpArSalesItemized
select ii.itemId, ii.productLine, ip.Descr, ii.Descr, 0,0,0,0,0, NULL
from tblInItem ii, tblInProductLine ip
where ip.productLine = ii.productLine
AND ii.itemId BETWEEN @itemIdFrom AND @itemIdThru

-- update table with this years quantities
update #tmpArSalesItemized
SET QtySold = (select SUM(QtyOrdSell) from tblArHistDetail hd
where TransId IN (select TransId from tblArHistHeader where custId = @custId)
AND orderDate IN (select OrderDate from tblArHistHeader where OrderDate BETWEEN @dateFrom AND @dateThru)
AND hd.partId BETWEEN @itemIdFrom AND @itemIdThru
GROUP BY hd.partId
)

-- Return the temp tables results
select * from #tmpArSalesItemized, #tmpArCustInfo

drop table #tmpArSalesItemized, #tmpArCustInfo

return


GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO


My problems begin where i want to start updating all of the Qty's of the QtySold field. I have managed to get it to write the same sum in every field but i cannot figure out how to update each row based on the sum of the qty found for that item in the tblArHistDetails table, trouble is too that there is no reference to the custId in that table either. The custId resides in tblArHistHeader and is linked to the details table via the TransId column. So really i need to update many rows based on criteria from 2 other tables.

Can anyone please help? I dont have a clue how to make this work, and most of what i have learned about sql thus far has been from opening other stored procs etc in the accounting system and just reading to see how the developers have done things.

Thanks
Jamie

Select Rows Based On Multiple Date Conditions

Jun 5, 2008

Hi,
I have 1 table with 5 rows. One of the rows has dateTime values. I want to know how many rows there are with a value in that column < today AND how many rows there are with a value in that column > today.
I'm not sure how to do this.

SELECT Count(*) WHERE dateColumn <= today AND dateColumn > today gives me everything.
I like to end up with a column containing the count of rows <= today
and a column with rows where date > today.

Is this possible in SQL or do I have to retrieve all rows and then loop over the resultset and check each row?

Thanks,
Marc

Combining Results Of Multiple Rows Based On Group?

Jul 17, 2013

I have a table of attributes set up as follows:

ID, Value, Group
1, Football, Sports
1, Baseball, Sports
1, Basketball, Sports
2, Baseball, Sports
3, Football, Sports
1, Lambda Sigma, Greeks
2, Delta Delta, Greeks
etc.

I want a query that will combine that values for each ID into one field per group. So if ID 1 has multiple sports but also a greek attribute, they end up with two rows; the first row containing the combined sports values and the second row the greek valued not combined, because there was only one value in that group for that ID. For example:

ID, Combined Values, Group
1, Football Baseball Basketball, Sports
2, Baseball, Sports
3, Football, Sports
1, Lambda Sigma, Greeks
2, Delta Delta, Greeks

Delete Multiple Rows One At A Time Based On A Condition

Aug 28, 2007



Hi,

I have the following scenario :
CustomerDetail
customerid
customername
status
app_no

[status = 0 means customer virtually deleted]

CustomerArchive
archiveno [autoincrement]
customerid
customername
status


At the end of the month, I have to physically delete customers. I have written two stored procs:

proc1
create proc spoc_startdeletion
as
declare @app_no int
select @app_no = (select app_no from customerdetail where status=0)
EXEC spoc_insertcustomerarchive @app_no
-- After transferrin, physically delete
delete from customerdetail where status=0

proc2
create proc spoc_insertcustomerarchive
@app_no int
as
insert into customerarchive(customerid,customername,status)
select customerid,customername,status from customerdetail where app_no = @app_no

It works fine if there is only one row with status=0, however the problem is that when there are multiple rows in customerdetail with status=0, it returns 'Subquery returned more than one value'

How can i transfer multiple rows one by one from the customerdetail to customerarchive and then delete the rows once they are transferred.

Insert Multiple Rows To Table Based On Values From Other 2 Tables.

Nov 21, 2007

I have a form to assign JOB SITES to previously created PROJECT.  The  JOB SITES appear in the DataList as it varies based on customer. It can be 3 to 50 JOB SITES per PROJECT.
I have "PROJECT" table with all necessary fields for project information and "JOBSITES" table for job sites. I also created a new table called "PROJECTSITES"  which has only 2 columns:  "ProjectId" and "SiteId".
What I am trying to do is to insert multiple rows into that "PROJECTSITES" table based on which checkbox was checked.  The checkbox is located next to each site and I want to be able to select only the ones I need. Btw the Datalist is located inside of a formview and has it's own datasource which already distincts which JOBSITES to display.
Sample:
ProjectId    -    SiteId
1   -   5
1    -   9
1    -   16
1    -   18
1    -   20
1    -   27
1    -   31
ProjectId stays the same, only values for SiteId are being different.
I hope I explaining it right. Do I have to use some sort of loop to go through the automatically populated DataList records and how do I make a multiple inserts to database table? We use SQL Server 2005 and VB for code behind. Please ask if I missed on some information. Thank you in advance.

Select Multiple Rows Based On Date Interval From Table

Apr 7, 2015

I have a table in which each record has a initial date and a final date. I would like to create I query that gives me one row for each month between the initial date and the final date. It would be something like this:

Original:

Product|price|initial_date|final_date
A|20.50|2014-08-10|2014-10-01
B|50|2015-01-15|2015-02-20

Resulting view:

A|20.5|2014-08-01
A|20.5|2014-09-01
A|20.5|2014-10-01
B|50|2015-01-01
B|50|2015-02-01

I would like to do that, because these dates correspond to the time in which the products are in possession of sellers, so I would to use this resulting query to generate a pivot chart in Excel to illustrate the value of the goods that are with our sellers in each month.

Is it possible to do it? I think I could do that direct in VBA, but I think that maybe it would be faster if I could do it directly in SQL.

By the way, I am using MS SQL Server and SQL Server Manegement Studio 2012.

SQL Server 2012 :: Update Table Based On Existing Values In Multiple Rows?

Oct 1, 2015

The objective is to identify orders where an order fee has been applied incorrectly. I have multiple orders per customer, my table contains an orderID and a customerID. Currently if the customer places additional orders before the previous orders have been closed/cancelled, then additional fees are being applied.

Let's say I'm comparing order #1 to order #2. I need to identify these rows where the following is true:-

The CustID is the same.

Order #2 has a more recent order date.

Order #2 has a FeeDate Before the CancelledDate of Order #1 (or Order #1 has no cancellation date).

So in the table the orderID:2835692 of CustID: 24643 has a valid order fee. But all the subsequently placed orders have fees which were applied before the first order was cancelled and so I want to update the FeeInvalid column with a 'Y'. The first fee will always be valid.

I think I understand why the code I am trying doesn't achieve the result I want but I can't figure out how to write it correctly. Below is one example of code I've tried and also code to create the table and insert some test data.

update t1
SET FeeInvalid = 'Y'
FROM MockData t1 Join MockData t2 on t1.CustID = t2.CustID
WHERE t1.CustID = t2.CustID
AND t2.OrderDate > t1.OrderDate
AND t2.FeeDate > t1.CancelledDate
CREATE TABLE [dbo].[MockData](
[OrderID] [float] NULL,

[code]....

Transact SQL :: Get Multiple Rows Based On Comma-separated Ntext List In On Column?

Jun 2, 2015

I have a table that is used to build rules. The rules point to other columns in other tables and usually contain only one value (i.e. ABC). But one of the options is to add a comma-separated list of SSNs (i.e. 123123123,012012012,112231122).  I am trying to build a single query that allows me to leverage that list to get multiple rows from another table.

This obviously works:

SELECT * FROM vw_Person_Profile P (NOLOCK)
WHERE P.PrsnPIISSN_Chr IN ('123123123','012012012','112231122')

But this does not:

SELECT * FROM vw_Person_Profile P (NOLOCK)
WHERE P.PrsnPIISSN_Chr IN (
SELECT '''' + REPLACE(CONVERT(VARCHAR(4000),txtFieldValue), ',', ''',''') + ''''
FROM MassProcessing_Rules PR
WHERE PR.intRuleID = 10
)

Calculating A Field Value Based On Other Records

May 20, 2008

I have two tables and they have a foreign key relationship.  It will be a 1 to Many realationship. 
Table1- the primary key table has the following columns
ContentID - int identity field
DateAdded- datetime
Table2 - The foreign key table, has the following relevant fields
FK - int foreign key
version - int
When an initial record is added there is a record added to each table.  The ContentID in Table1 will match the FK field in Table2.  Then a user will be able to "edit" the record in Table2, but instead of writing over the record that is already there, a new record will be added to Table2.  I would like to calculate the version field where each time a record is added for the particular ContentID/FK it adds 1 to the last version that was added to that particular ContentID/FK. 
 Does that make sense.  I am trying to implement some type of revision tracking for my CMS that I am building and this is the only way I can come up with because my client is worried that somebody will go in and make incorrect changes to their site and  they want to be able to roll it back to a previous version. 
I would appreciate any ideas.
Thanks,
laura

Calculating %ages Based On A List...

Aug 2, 2007

Hey all! First post-- I apologize for the newbness of the question, but I'm having an issue with a basic query... here goes:

I want to calculate the percentages of statuses found from two tables. Let say T1 is my list of statuses:

T1
Passed
Failed
Not Completed

and T2 is the table where I derive my total # of statues for each id and how many in each status.

T2
ID, Desc, Status , numtimesinstatus
1, Test1, Failed, 3
1, Test1, Passed, 1
3, Blah, Failed, 5
3, Blah, Not Completed, 1

What I'd like to do is get the percentages for each available status in T1, from T2-- I can do this; however, I'm having trouble in the cases where a particular ID hasn't been in one of the status (in other words, calculating a 0%). What I'd like to get from these two tables is:

Result
ID, Desc, Status, %age
1, Test1, Failed, 75.0
1, Test1, Passed, 25.0
1, Test1, Not Completed, 0.0
3, Blah, Failed, 83.3
3, Blah, Passed, 16.67
3, Blah, Not Completed, 0.0

Can anyone shed some light? Thanks!

SP To Perform Query Based On Multiple Rows From Another Query's Result Set

Nov 7, 2007

I 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!

Calculating Length Of Service Categories Based On Start Dates

May 1, 2007

Ok, so I've been struggling with the logic behind this one for a while, so I thought I'd ask you guys for some ideas :)

Basically, I have the following table structure
Employee(employee_number, continuous_start_date, ...)

The problem lies in working out a summary of service categories (0-6months, 7-12months, 13-24, 25+).
I can work out the length of service in months with the following code

SELECT DateDiff(mm, continuous_start_date, GetDate()) AS 'Service in months'
FROM employee

So the first stage is to summarise the length of service into groups as mentioned above.

Then the final stage is working out how many people are in each group!

Hope I have given enough information - and please do not post a full solution - just some hints on how to get the desired result ;)

Thanks later, and in advance :p

What I want is to use the subtotal as a variance-field for the two selected years by the user. It could happen that a customer doesn't generate turnover in one year, then the subtotal has to be 0 or 100 or whatever.

If my suggestions aren't applicable then I'd like to know If there is another possibility to display the desired results.

Thanks!

Calculating Average From Rows Entries..

Mar 19, 2008

Dear all,

I havea table name HISTORY_MEASURE which is a collection of different measure value issue from different mesuring device.

Values inthis table is represented as follow :

Id Name Value
==============================
1 Diameter1 0.45
2 Diameter2 1.23

3 Temperature2 123
4 Temperature2 200
5 Diameter1 0.65

Out of this table what I need to do is calculate the average value for each same [Name]. As you can see from the sample set above, the Diameter1 has 2 entries value hich gets store at different time of course.

So I I take the example of Diameter1 I need to calculate and display in a field the average results.
The result would be

Name Average
=====================
Diameter1 .....
Diameter2 ....
Temperature2 ....
Temperature1 ....


How can I perform this ?

Or could it be better to get a view of the table above which gets display as follow :

Diameter1 Temperature2 Diameter2
0.45 123 1.23
0.65 200 0



Thanks fro your help

Calculating Change Of Values Between Rows

Aug 23, 2007

Hello forum.


I have three columns in my table with the following datatypes:

Date - DateTime
Height - Decimal
Change_From_last_Height - Decimal

I am using "SQL Server 2005 Express Edition". I'm fairly new to SQL and would greatly appreciate any help or advice I can get.

The "date" column increases by an extra day in every new row and I then enter the new height of the plant. What I want to know is how I can get SQL server express to automatically enter the difference in height between the current row's height and that of the previous row.

Is it possible to automate the entry in the Change_From_Last_Height column in SQL?

Put another way, I know how to find the difference between two values in the same row but different columns, but how do I calculate the difference between values in adjacent Rows (ie. Rows next to each other)?


Thank you.

Help Needed With Calculating Average For Both Parent And Child Rows

Mar 29, 2008

I am trying to create a SSRS report that needs to show average for both parent and child rows. In the example below i need to show an average of ErrorRecAge column for Company, then for cic_Group and one grand total/avg. How can this be done from single query (as below) and using SSRS built in functions/codes? I am also curious to know if this can be done from TSQL directly (ex. something similar to running sum/total). I appreciate the help.


Select


CustomerCorrection.Id As ParentId,

cc_company As cc_company2,

ccError.Id As ErrorId,

COALESCE(cic_Group,'Other Errors') As cic_Group,

COALESCE(cic_Code,'Unknown') As ErrorCode,COALESCE(cic_Description,'Unknown') As ErrorDescription,

DateDiff(hh,cc_entrydt,getdate())/24.00 AS ErrorRecAge

From


CustomerCorrection Inner Join CCError On

CustomerCorrection.Id = CCError.CustomerCorrectionId

Left Outer Join CustomerImportControl On

cic_code = ce_errno

Where cc_company = 'IWA' And CustomerCorrection.Id In (129,1004,3228)

Order By CustomerCorrection.Id



That Returns
129 IWA 992 Other Errors Unknown Unknown 399.500000
129 IWA 1089 Other Errors Unknown Unknown 399.500000
129 IWA 1760 Other Errors Unknown Unknown 399.500000
1004 IWA 952 Other Errors Unknown Unknown 365.333333
1004 IWA 1853 Other Errors Unknown Unknown 365.333333
3228 IWA 10 Other Errors Unknown Unknown 329.375000

Here is my temp workaround:

Select a.*,b.*

From


(

Select

cc_Company, Count(Distinct CustomerCorrection.Id) as RecCount, Avg(DateDiff(hh,cc_entrydt,getdate()))/24.00 As RecAge

From

CustomerCorrection

Group By cc_Company

) As a

Inner Join


(

Select

cc_company As cc_company2,

COALESCE(cic_Group,'Other Errors') As cic_Group,

Count(Distinct ccError.Id) As ErrorRecCount,

AVG(DateDiff(hh,cc_entrydt,getdate()))/24.00 As ErrorRecAge

From

CustomerCorrection Inner Join CCError On

CustomerCorrection.Id = CCError.CustomerCorrectionId

Left Outer Join CustomerImportControl On

cic_code = ce_errno

Group By cc_company, COALESCE(cic_Group,'Other Errors')

) as b

On a.cc_company = b.cc_company2

Order By cc_Company,cic_group

Compare Values In Consecutive Rows And Print Rows Based On Some Conditions

May 8, 2008

I have the following variables VehicleID, TransactDate, TransactTime, OdometerReading, TransactCity, TransactState.

VehicleID is the unique vehicle ID, OdometerReading is the Odometer Reading, and the others are information related to the transaction time and location of the fuel card (similar to a credit card).

The records will be first grouped and sorted by VehicleID, TransactDate, TransactTime and OdometerReading. Then all records where the Vehicle ID and TransactDate is same for consecutive rows, AND TransactCity or TransactState are different for consecutive rows should be printed.

I also would like to add two derived variables.

1. Miles will be a derived variable that is the difference between consecutive odometer readings for the same Vehicle ID.

2. TimeDiff will be the second derived variable that will categorize the time difference for a particular vehicle on the same day.

My report should look like:

VehID TrDt TrTime TimeDiff Odometer Miles TrCity TrState
1296 1/30/2008 08:22:42 0:00:00 18301 000 Omaha NE
1296 1/30/2008 15:22:46 7:00:04 18560 259 KEARNEY NE

Can someone please help me here?

Thanks,
Romakanta

Calculating Data From Multiple Tables

Aug 29, 2014

I have a table which contains readingtime (records every 4 seconds during the day) and an energy reading. I wanted to know how much energy was used in a day. This is the query that i used

SELECT date(readingtime), max(energy)-min(energy)as total FROM lights_1 WHERE readingtime between 20140407000000 and 20140409235959 Group by date(readingtime) LIMIT 0,30;

This gave me the desired results for 1 table. I have 4 tables of these lights_2, Lights_3, lights_4 and i would like to display them together and hence match up the reading time so each day has the energy requirements for all for tables with the total. When i try and join tables i get a lot of errors!
