My code:
Group BY
GROUPING SETS
(
(wmsSponsorEntityName),
(wmsSponsorEntityPrimaryRegion),
(wmsProjectNameSWP) ,
()
)
I'm doing this because those three fields repeat and the other two:
w.[P2010]
w.wugCounty
differ for some wmsProjectNameSWP
wmsSponsorEntityName | wmsSponsorEntityPrimaryRegion | wmsProjectNameSWP | w.wugCounty | P2010
ABERNATHY | O | Local groundwater development | LUBBOCK | 808
ABERNATHY | O | Local groundwater development | HALE | 2297
But I receive an error of Incorrect syntax near 'SETS'.
Any guidance would be appreciated.
GROUPING SETS was introduced in SQL Server 2008. Which means if you are on SQL Server 2005, you will get a syntax error since it doesn't exist.

I have a complex production SQL question. It's actually PrestoDB Hadoop, but conforms to common SQL.
I've got to get a bunch of metrics from a table, a little like this (sorry if the tables are mangled):
+--------+--------------+------------------+
| device | install_date | customer_account |
+--------+--------------+------------------+
| dev 1 | 1-Jun | 123 |
| dev 1 | 4-Jun | 456 |
| dev 1 | 10-Jun | 789 |
| dev 2 | 20-Jun | 50 |
| dev 2 | 25-Jun | 60 |
+--------+--------------+------------------+
I need something like this:
+--------+------------------+-------------------------+
| device | max_install_date | previous_account_number |
+--------+------------------+-------------------------+
| dev 1 | 10-Jun | 456 |
| dev 2 | 25-Jun | 50 |
+--------+------------------+-------------------------+
I can do two separate queries to get max install date and previous account number, like this:
select device, max(install_date) as max_install_date
from (select [a whole bunch of stuff], dense_rank() over(partition by device order by [something_else]) rnk
from some_table a
)
But how do you combine them into one query to get one line for each device? I have rank, with statements, case statements, and one join. They all work individually but I'm banging my head to understand how to combine them all.
I need to understand how to structure big queries.
ps. any good books you recommend on advanced SQL for data analysis? I see a bunch on Amazon but nothing that tells me how to construct big queries like this. I'm not a DBA. I'm a data guy.
Thanks.
You can use correlated subquery approach :
select t.*
from table t
where install_date = (select max(install_date) from table t1 where t1.device = t.device);
This assumes install_date has resonbale date format.
I think you want:
select t.*
from (select t.*, max(install_date) over (partition by device) as max_install_date,
lag(customer_account) over (partition by device order by install-date) as prev_customer_account
from t
) t
where install_date = max_install_date;
I'm trying to create a query in SQL Server to determine how many times a person's name shows up in a list, but also that list will be unknown, so I would have to get the actual name from the previous select index... It's hard to explain so I'll show the query first and hopefully someone can help.
SELECT
SpeakerName, Spoken,
(SELECT COUNT(SpeakerName)
FROM tbl_SpeakerCard_Log
WHERE SpeakerName = 'SpeakerName[i]' AND SpeakDate = '3-9-16') as TimesSpoken
FROM
tbl_SpeakerCard_Log
WHERE
AID = ####
ORDER BY
GeneralComment ASC
So basically, in SpeakerName[i], I'd like to somehow get the SpeakerName from the outer Select. The output should come out something like this
+-------------+--------+-------------+
| SpeakerName | Spoken | TimesSpoken |
+-------------+--------+-------------+
| Holly | 0 | 4 |
| Robert | 1 | 5 |
| Mike | 1 | 2 |
+-------------+--------+-------------+
Try this:
select x.SpeakerName, x.Spoken, COUNT(*) as TimesSpoken
from tbl_SpeakerCard_Log x
WHERE AID = ####
and x.SpeakDate = '3-9-16'
group by x.SpeakerName, x.Spoken
Don't have SSMS installed on this computer so can't test it.
I'm new in SQL and I'm trying to select column Foto_municipis:
askdbase4=# select * from avatar_avatarx;
id | llista_municipis | Foto_municipis | primary | date_uploaded
----+------------------+-----------------+---------+------------------------
1 | Tore | tore.jpg | t | 2014-06-05 01:19:40+02
2 | Calldetenes | calldetenes.jpg | f | 2014-06-05 23:24:18+02
3 | Rupit i Pruit | baixa.jpeg | f | 2014-06-16 03:09:48+02
4 | Olost | olost.jpg | f | 2014-06-16 23:20:05+02
(4 rows)
for some reason I can select llista municipis successfully:
SELECT llista_municipis FROM avatar_avatarx;
but when I try to select Foto_municipis this is what I get:
askdbase4=# SELECT llista_municipis FROM avatar_avatarx;
ERROR: column "Foto_municipis" does not exist
LINE 1: select Foto_municipis from avatar_avatarx;
What am I doing wrong?
You probably created the column with a double-quoted identifier and this will work:
select "Foto_municipis"
from avatar_avatarx
That is almost always a bad idea as it will be forever necessary to reference it using double-quotes, unless it is an all lower case identifier in which case it can be referenced in lower case without double quotes.
If the column is created with an identifier without double quotes then it is possible to reference it in any case style like Foto_municipis or foto_Municipis regardless of the original identifier case style.
I have some problems regarding a pivot query. I am new to this. So look for something in the internet so I found dozens of them. So I decided to follow this Link. Been practice but seems like I ran into some obvious error.
My code is:
select
risk, [Quick] AS Quick, [Brown] AS Brown, [Fox] AS Fox
from
(select risk, site
from tst) as ps
PIVOT
(
count(risk)
for site in ([Brown], [Brown], [Fox])
) AS pvt
But it is throwing an error:
Invalid column name 'risk'.
Basically I want to have an output like this:
|Foo | Quick | Brown | Fox |
| 1 | 10 | 3 | 2 |
| 2 | 5 | 4 | 4 |
| 3 | 4 | 1 | 5 |
| 4 | 2 | 3 | 7 |
| 5 | 3 | 2 | 1 |
Something like that. Just counting how many there is in a specific number. Any help would be much appreciated. Thanks
The problem with your existing query is you are using the column risk in your final select list as well as inside of the aggregate function. Once you've counted the risk values for each site this is not available to display.
To get around this you can add a second version of the risk column to your subquery similar to the following. You then count this other column of risk and display one in the final select:
select risk, [ADAB] AS ADAB, [Bahrain] AS Bahrain, [Thumrait] AS Thumrait
from
(
select risk, piv_risk = risk, site
from qcqcif
) as ps
PIVOT
(
count(piv_risk)
for site in ([ADAB], [Bahrain], [Thumrait])
) AS pvt;
See SQL Fiddle with Demo
When performing SELECT statements including number columns (prices, for example), the result always is left to right ordered, which reduces the readability. Therefore I'm searching a method to format the output of number columns right to left.
I already tried to use something like
SELECT ... SPACE(15-LEN(A.Nummer))+A.Nummer ...
FROM Artikel AS A ...
which gives close results, but depending on font not really. An alternative would be to replace 'SPACE()' with 'REPLICATE('_',...)', but I don't really like the underscores in output.
Beside that this formula will crash on numbers with more digits than 15, therefore I searched for a way finding the maximum length of entries to make it more save like
SELECT ... SPACE(MAX(A.Nummer)-LEN(A.Nummer))+A.Nummer ...
FROM Artikel AS A ...
but this does not work due to the aggregate character of the MAX-function.
So, what's the best way to achieve the right-justified order for the number-columns?
Thanks,
Rainer
To get you problem with the list box solved have a look at this link: http://www.lebans.com/List_Combo.htm
I strongly believe that this type of adjustment should be made in the UI layer and not mixed in with data retrieval.
But to answer your original question i have created a SQL Fiddle:
MS SQL Server 2008 Schema Setup:
CREATE TABLE dbo.some_numbers(n INT);
Create some example data:
INSERT INTO dbo.some_numbers
SELECT CHECKSUM(NEWID())
FROM (VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1))X(x);
The following query is using the OVER() clause to specify that the MAX() is to be applied over all rows. The > and < that the result is wrapped in is just for illustration purposes and not required for the solution.
Query 1:
SELECT '>'+
SPACE(MAX(LEN(CAST(n AS VARCHAR(MAX))))OVER()-LEN(CAST(n AS VARCHAR(MAX))))+
CAST(n AS VARCHAR(MAX))+
'<'
FROM dbo.some_numbers SN;
Results:
| COLUMN_0 |
|---------------|
| >-1486993739< |
| > 1620287540< |
| >-1451542215< |
| >-1257364471< |
| > -819471559< |
| >-1364318127< |
| >-1190313739< |
| > 1682890896< |
| >-1050938840< |
| > 484064148< |
This query does a straight case to show the difference:
Query 2:
SELECT '>'+CAST(n AS VARCHAR(MAX))+'<'
FROM dbo.some_numbers SN;
Results:
| COLUMN_0 |
|---------------|
| >-1486993739< |
| >1620287540< |
| >-1451542215< |
| >-1257364471< |
| >-819471559< |
| >-1364318127< |
| >-1190313739< |
| >1682890896< |
| >-1050938840< |
| >484064148< |
With this query you still need to change the display font to a monospaced font like COURIER NEW. Otherwise, as you have noticed, the result is still misaligned.
