I have a table where I have the following columns - lets call location table
city, state, zipcode, lat, lng
The problem is that every city and state can multiple zip codes e.g.
belleuve, wa, 98004
bellevue, wa, 98006
Similarly a city name can be also present in some other state e.g.
bellevue, TN, 05156
How do I select a distinct city e.g. Bellevue for each state. Basically the result should show both Bellevue, WA and Bellevue, TN but for WA only one occurance of Bellevue.
Grouping by the city and state should work here:
SELECT City, State
FROM yourTable
GROUP BY City, State;
We also could use DISTINCT:
SELECT DISTINCT City, State
FROM yourTable;

I'm not finding any other questions exactly like mine, so it's time to ask.
I have an SSRS 2016 report. It's got a regional hierarchy (State, City, Location). And it's got one measure column that is a calculation performed in the stored procedure. Due to the nature of the calculation, the value of the calculation for a city must be performed independently in the stored procedure. It's not a simple aggregation of the Locations in the City, so it cannot simply be aggregated in the report. I need the report to expand and contract on the regional hierarchy columns, and to pull the measure values straight from the dataset with aggregating.
In other words
I have a dataset like this:
State City Location Measure
FL NULL NULL 25
FL Miami NULL 12
FL Miami Walmart 52
FL Miami Kmart 3
FL Orlando NULL 33
FL Orlando Sears 4
I need for the report to have collapsible rowgroups at the State and City levels, with Location being the "detail" level row group. But I need the value of Measure to be 12 for Miami, and not some aggregation of 2 & 3 (Walmart and Kmart).
I figure the approach must be either:
Use traditional row groups and do some kind of programming in the expression of the measure column for the two upper-level row groups, or
Don't put row groups on the tablix and do conditional formatting of the rows and some kind of programming in the toggle properties.
But in both cases, I'm not seeing anything I can do that SSRS will actually allow for the "some kind of programming" bit.
Is there a solution?
If you must do it in the report, I think you could use a table a FILTER out the NULL city and location values. When you need them you could do a Lookup to get the value from the dataset. This will lookup the Measure value for a City where the IIF will act as a filter for the NULL value - if there is a location the City will have an X0 added and won't match the Lookup City.
=Lookup(Fields!City.Value, Fields!City.Value & IIF(ISNOTHINGFields!Location.Value), "", "x0"), Fields!Measure.Value, "Dataset1")
If you can put your current results in a temp table, a better way would be to add the totals as seperate fields in the query.
SELECT 'FL' AS State, NULL AS City , NULL as Location, 25 as Measure
INTO #TABLE
UNION
SELECT 'FL' AS State, 'Miami' AS City , NULL AS Location, 12 as Measure
UNION
SELECT 'FL' AS State, 'Miami' AS City , 'Walmart' as Location, 52 as Measure
UNION
SELECT 'FL' AS State, 'Miami' AS City , 'Kmart' as Location, 3 as Measure
UNION
SELECT 'FL' AS State, 'Orlando' AS City , null as Location, 33 as Measure
UNION
SELECT 'FL' AS State, 'Orlando' AS City , 'Sears' as Location, 4 as Measure
--DROP TABLE #TABLE
SELECT T.*, T_S.Measure AS STATE_MEASURE, T_C.Measure AS CITY_MEASURE
FROM #TABLE T
LEFT JOIN #TABLE T_S ON T.State = T_S.State AND T_S.City IS NULL
LEFT JOIN #TABLE T_C ON T.State = T_C.State AND T_C.City = T.City AND T_C.Location IS NULL
WHERE T.City IS NOT NULL AND T.Location IS NOT NULL
This will let you just have the recordsd you need with the additional comlumns for the summary data.
Group on state and city and don't use SUM() for your Measure column
Your layout could be like the one below
I have 2 tables, country and division with the ff schemas:
country division
----------- ------------
countrycode divisioncode
contryname countrycode
divisionname
I want to copy data from the country table into the division table where countrycode goes into divisioncode and countrycode in division table and countryname going into divisionname
For ex, US - United States goes into the division table as US, US, United States.
Use INSERT INTO ... SELECT
Query
INSERT INTO division(divisioncode, countrycode, divisionname)
SELECT countrycode, countrycode, countryname
FROM country;
insert into division (divisioncode, countrycode, divisionname)
select t1.countrycode, t1.countrycode, t1.countryname
from country t1
See: http://dev.mysql.com/doc/refman/5.7/en/insert-select.html
I'm trying to get data from database in this format:
state
|__city
| |__address
| |__zip
I want all unique states and cities with all addresses and zip codes concatenated.
Here's what I've tried:
SELECT
state,
GROUP_CONCAT('(',address,';)') AS address,
GROUP_CONCAT('(',zip,';)') AS zip
FROM location
WHERE
sername='ABC#gmail.com'
GROUP BY state,city
UPDATE
There is problem with concatenation. I want the data in this format:
state city address zip
Karnataka BANGALORE (sdbsbd);(dsdsds); NULL
and I'm getting data as
state city address zip
Karnataka BANGALORE (sdbsbd);,(dsdsds); NULL
I don't want the comma in the address:
;,
I think you need the SEPERATOR argument in the GROUP_CONCAT() function.
https://dev.mysql.com/doc/refman/5.0/en/group-by-functions.html#function_group-concat
SELECT state, GROUP_CONCAT('(',address,';)' SEPARATOR '') as
address,GROUP_CONCAT('(',zip,';)' SEPARATOR '') as zip FROM location Where
username='ABC#gmail.com' GROUP BY state,city"
I have a query.I have table with two columns country and state.I want to display columns in following format
Country State
----------- ---------
India Delhi
Bangalore
Kolkata
Mumbai
USA California
Florida
Las Vegas
Virginia
It means "India" just appear one time in country column and and repeated values would come as blank value in country column when i select country and state from table.
Thanks in advance
Presentation is usually if not always better done outside of SQL so I'd recommend doing this in whatever your presentation layer runs, but if it's a requirement for the query, you can do it using session variables;
SELECT Country, State FROM (
SELECT IF(Country=#country, '', Country) Country, State, #country := Country
FROM (SELECT Country, State FROM Table1 ORDER BY Country, State) dummy1,
(SELECT #country:='') dummy2
) dummy3;
An SQLfiddle to test with.
Just to show a (probably) better way, you can use this to get a list of states per country, and process it further in your presentation layer;
SELECT Country, GROUP_CONCAT(State) FROM Table1 GROUP BY Country;
Another SQLfiddle.
use pl/sql.Moreover your table would be voilating 5th normal form.
I have a Users table with these values (stripped down for the example):
Name
City
County
StateProvince
Country
Continent
Strength
Endurance
Intelligence
I basically want a query that returns the highest stat by region for yourself. If you have the highest Strength (67) in the country, highest Endurance (59) in your City, and not the highest Intelligence anywhere, I'd like a 2 row result of:
('Strength', 67, 'Country', 'United States')
('Endurance', 59, 'City', 'Redmond')
Note that if you have the highest Strength in the country, you will also have the highest strength in the state/province, county, and city (but I'd like those not to be returned in the result). I can do this all using multiple SELECT queries, however, I'd like to know how to do this in one single query for efficiency (or if that's even a good idea?). I'd imagine the logic would go something like (pseudo code):
(SELECT FROM Users ORDERBY Strength WHERE Country = 'MyCountry' LIMIT 1) IF Name != 'Me' (SELECT FROM Users ORDERBY Strength WHERE StateProvince = 'MyState' LIMIT 1) ... and so on
Furthermore, the above would also need to work with Endurance and Intelligence. Thanks!
