How can i write a sql query in my sql where i have many columns like(name, age, weight, salary, demography, loan status) from various table and last_recorded_date column without using group by function ?
I dont want to use
SET SESSION sql_mode = sys.list_add(##session.sql_mode, 'ONLY_FULL_GROUP_BY');
The method i use right now is
select a.name,a.age,a.weight, b.salary,c.demography,d.loan_type,d.loan_amt,
max(d.recordeddate) as last_recorded date
from cust_details a,applicanttable b, applicanttype b,masterloan d
where a.name=b.name and a.age=c.age and a.city=d.region
group by d.loanid;
Is there any other way to write the above query without using group by function ?

In my project I am using datatables plugin with serverside processing. It works fine untill i do a search or order(sort) operation because it needs active record to do that.
My scenario is, i have an account table, revenue table and payment table, and I want to view all the data of revenue and payment table, thats why I need a union. my query is like below---
SELECT 'Income' as source, fld_type, fld_amount, ta.fld_account as account, fld_date, tbl_revenue.fld_description as fld_traninfo, tbl_revenue.fld_created as created
FROM tbl_revenue JOIN tbl_accounts as ta on tbl_revenue.fld_account_id = ta.fld_id
UNION
SELECT 'Expense' as source, fld_type, fld_amount, tae.fld_account, fld_date, tbl_payment.fld_description as fld_traninfo, tbl_payment.fld_created as created
FROM tbl_payment JOIN tbl_accounts as tae on tbl_payment.fld_account_id = tae.fld_id
Is there any way to use query builder in this query?
And second question, you can see I created a virtual column named 'source', i want to filter this column using where clause with append this query like below
WHERE source like "%a%" limit(10,0)
But this returns that I don't have any column name 'source', how can I filter this column?
Any help is appreciated.
there is a way to do that but its a bit hacky because codeigniter's querybuilder adds an auto SELECT statement to the query if you didn't specify it by yourself
In order to get what you want, you've to split your select statements in 2 queries and add the where clause to this query
Something like that should work:
$strQuery1 = $this->db
->select('income as source, fld_type, fld_amount, ta.fld_account as account, fld_date, tbl_revenue.fld_description as fld_traninfo, tbl_revenue.fld_created as created')
->from('tbl_revenue')
->join('tbl_accounts as ta', 'tbl_revenue.fld_account_id = ta.fld_id')
->get_compiled_select();
$strQuery2 = $this->db
->select('Expense as source, fld_type, fld_amount, ta.fld_account as account, fld_date, tbl_revenue.fld_description as fld_traninfo, tbl_revenue.fld_created as created')
->from('tbl_payment')
->join('tbl_accounts as ta', 'tbl_revenue.fld_account_id = ta.fld_id')
->get_compiled_select();
$strWhere = substr($this->db->like('source', 'a', 'both')->get_compiled_select(), 8);
$query = $this->db->query($strQuery1.' UNION '.$strQuery2.$strWhere);
I am trying to display a warning if a bike station gets to over 90% full or less than 10% full. When i run this query I get "you are trying to execute query that does not include the iif statment... as part of an aggregate function.
Bike_locations table - Bicycle_id and Locations_ID
Locations table - Locations_ID, No_of_Spaces, Location_Address
SELECT Locations.Location_Address, Count(Bike_Locations.Bicycle_ID) AS CountOfBicycle_ID,
IIf(((([CountOfBicycle_ID]/[LOCATIONS]![No_Of_Spaces])*100)>90),"This Station is nearly full.
Need to move some bicycles out of here",IIf(((([CountOfBicycle_ID]/[LOCATIONS]![No_Of_Spaces])*100)
<10),"This station is nearly empty. Need to move some bicycles here","")) AS Warnings
FROM Locations INNER JOIN Bike_Locations ON Locations.[LOCATIONS_ID] = Bike_Locations.[LOCATIONS_ID]
GROUP BY Locations.Location_Address;
Anyone got a scooby
When you use a GROUP BY, you should have the exact same fields in both your SELECT and GROUP BY statements, except for the aggregate function that should only be specified in the SELECT
The aggregate function in your case is the COUNT(*)
The fields you aggregate on are:
in the SELECT : Location_Address and Warnings
in the GROUP BY : Location_Address only
The error message is telling you that you don't have the same in both statements.
2 solutions:
Remove the Warnings from the SELECT statement
Add the Warnings to the GROUP BY statement
Note that in MS Access SQL, you can't (unfortunately) use in the GROUP BY, the Aliases specified in the SELECT. So you have to copy over the whole field, which would be the long iif in your case
Edit: better solution proposal:
I would radically change your approach as you'll go no where with all those nested iff
Create the following Query and Name it (for instance) Stations_Occupation
SELECT L.Locations_ID AS ID,
L.Location_Address AS Addr,
L.No_of_Spaces AS TotSpace,
BL.cnt AS OccSpace,
ROUND((BL.cnt/L.No_of_Spaces*100),0) AS OccPourc
FROM Locations L
LEFT JOIN
(
SELECT Locations_ID, COUNT(*) AS cnt
FROM Bike_Locations
GROUP BY LOCATIONS_ID
) AS BL ON L.Locations_ID = BL.Locations_ID
This query will probably be a lot helpfull in many parts of your application, and not only here, as it calculates the occupation % of each station
Some examples:
Get all stations with >90% occupation:
SELECT Addr
FROM Stations_Occupation
WHERE OccPourc > 90
Get all stations with <10% occupation:
SELECT Addr
FROM Stations_Occupation
WHERE OccPourc < 10
Get Occupation level of a specific station:
SELECT OccPourc
FROM Stations_Occupation
WHERE ID=specific_station_ID
Get number of bikes and max on a specific station:
SELECT OccSpace & "/" & TotSpace
FROM Stations_Occupation
WHERE ID=specific_station_ID
Ive got a simple query that is used on a search. My problem is with this query is that as the records in mysql are added everytime there is a transaction, the query returns a list of data when there could only be one or a few more rows instead of a lot more.
SQLFliddle
As you can see here - the query returns a lot of rows, where I want it to return
BLSH103 A001A 31 24/01/2014
Can the qty where the product name & pallet space are the same be summed? And then show the largest date?
just use a sum function on t.Quantity (and a group by clause)
SELECT (t.ProductName) as Pname ,(s.PalletSpace) as PSpace, sum(t.Quantity) as Qty,(t.TransactionDate) as Transac
FROM PalletSpaces s
JOIN ProductTrans t
ON s.PalletSpaceID = t.PalletSpace
WHERE t.ProductName LIKE 'BLSH103' OR s.PalletSpace LIKE 'BLSH103'
group by
Pname,
pSpace,
Transac -- if you want to group by date also...
By the way, using LIKE this way (without %) doesn't make much sense...
see SqlFiddle
You just need to use GROUP BY and SUM in this way:
SELECT (t.ProductName) as Pname ,(s.PalletSpace) as PSpace, SUM(t.Quantity) as Qty,(t.TransactionDate) as Transac
FROM PalletSpaces s
JOIN ProductTrans t
ON s.PalletSpaceID = t.PalletSpace
WHERE t.ProductName LIKE 'BLSH103' OR s.PalletSpace LIKE 'BLSH103'
GROUP BY t.ProductName, s.PalletSpace;
Trying to convert below query into SQL, query works fine on MySQL. Problem seems to be the GROUP BY area. Even when I use just 1 GROUP BY field I get same error. Using query in InformaticaCloud.

Your entire query isn't going to work. The group by statement contains a single expression, the summation of a bunch of fields. The select statement contains zillions of columns without aggregates. Perhaps you intend for something like this:
select resp_ins, resp_payor_grouping, carrier_code, state, Collector_Name,
sum(Cast(Resp_Ins_Open_dol AS decimal(10,2))) as baltotal
from Config_21Cent
WHERE resp_ind = 'Insurance'
GROUP BY resp_ins, resp_payor_grouping, carrier_code, state, Collector_Name;
THis will work in both databases.
The columns in SELECT statement must be a subset (not proper subset but subset) of columns in 'GROUP BY' statement. There is no such restriction on aggregates in SELECT statement though. There could be any number of aggregates; aggregates even on columns not in GROUP BY statement can be included.
I'm stuggling to replicate a SQL query into LINQ.
Can any one help?
SQL:
SELECT tblInvoice.lngID AS InvoiceID,
tblInvoice.dtTimeStamp AS InvoiceDate,
tblInvoice.strReference,
tblInvoice.fltTotalValue,
max(Project.ProjectID) AS ProjectID,
max(Project.ProjectName) AS ProjectName,
max(Project.Location) AS ProjectLocation
FROM tblInvoice INNER JOIN
tblInvoiceLine ON tblInvoice.lngID = tblInvoiceLine.lngInvoiceID
WHERE (tblInvoice.intStatus != 0)
AND (tblInvoice.lngPersonID = #PersonID)
GROUP BY tblInvoice.lngID, tblInvoice.dtTimeStamp, strReference, fltTotalValue
ORDER BY tblInvoice.lngID DESC
LINQ so far:
var invoices = from inv in db.TblInvoices
join invLine in db.TblInvoiceLines on inv.LngID equals invLine.LngInvoiceID
where inv.IntStatus != 0
where inv.LngPersonID == personID
group inv by new {inv.LngID,inv.DtTimeStamp,inv.StrReference,inv.FltTotalValue} into newInv
Part of the problem is that I want to do a
select new Invoice(){
}
and build up my custom Invoice object but, I cant see any of the properties in newInv.
Can any one advise?
I don't have time for a full answer now, but:
To get at properties of the key, use newInv.Key.StrReference etc
To get at aggregates (e.g. max values) use newInv.Max(x => x.ProjectId) etc
Hopefully that'll be enough to get you going. Basically, newInv will be a group of entries, with an associated key (which is what you grouped by).
