I have a project where I create a query string dynamically. It's not too complicated, just complex. I specifically have a problem adding a select into the mix. Studio adds an "as" when I save the view.
SELECT TOP (100) PERCENT dbo.Users.ID AS UserId, dbo.Users_Info.Home_Area_Code, dbo.Users_Info.Work_Area_Code, dbo.Users_Info.State AS HomeState,
(CASE WHEN (dbo.Users_Info.Address1 = '' OR
dbo.Users_Info.Address1 IS NULL) THEN 0 ELSE 1 END) AS has_home_address, (CASE WHEN dbo.users.ID NOT IN
(SELECT UserID
FROM Users_Client_Companies) THEN 1 ELSE 0 END) AS Eliminate_TSI_Clients, (CASE WHEN dbo.users.ID IN
(SELECT individual_number
FROM qUsersPresented_ES) THEN 1 ELSE 0 END) AS Presented_ES, (CASE WHEN dbo.users.ID IN
(SELECT individual_number
FROM qUsersPlaced_ES
WHERE isnull(date_of_placement, '') > '') THEN 1 ELSE 0 END) AS Placed_ES, (CASE WHEN dbo.users.ID IN
(SELECT individual_number
FROM qUsersPresented_CS) THEN 1 ELSE 0 END) AS Presented_CS, (CASE WHEN dbo.users.ID IN

dbo.Users_Salary.ISCPCT AS Corporate_Letter_Per, (CASE WHEN (dbo.Users_Info.Basic_JobAd = 1 OR
dbo.Users_Info.Custom_JobAd = 1 OR
dbo.Users_Info.Elite_JobAd = 1 OR

WHERE (contact_id = dbo.Users.ID)) AS Date_Purchased_EJA,
dbo.Users_Salary.ISTEC1 AS Technical_Federal_Per,
dbo.Users_Salary.ISTEC2 AS Technical_StateLocal_Per,
The view QEliteContacts is as follows:
SELECT bd.date_purchased, bd.ID, csc.contact_id
FROM dbo.Board_Details AS bd LEFT OUTER JOIN
dbo.Client_Services_Contacts AS csc ON csc.service_id = bd.ID
WHERE (bd.ad_type LIKE '%Elite%')
Near the bottom of the first block of code is the statement "(SELECT MAX(date_purchased) AS EJA_Date_Purchased". This is the new code I have added to the view. I get and error "invalid syntax near 'as'". If I remove the alias from the max(date_purchased) studio will add 'as expr1' when I save the view. If I remove the alias from the select, studio will add 'as expr1' when I save the view.
To tell the truth, I'm not sure I'm attacking the problem of getting the max date properly.
Remove the second 'as'.ie, remove the portion ' AS Date_Purchased_EJA ' and give that instead of ' AS EJA_Date_Purchased '.In effect there should be only the first 'AS' statement.Then execute the query in Query Designer window and not in View Designer Window.The code is shown below.

I have the following script,
SELECT COUNT(*) AS Total,
SUM(CASE WHEN TypeId ='4' THEN 1 ELSE 0 END) AS 'TotalCount1',
SUM(CASE WHEN TypeId ='6' THEN 1 ELSE 0 END) AS 'TotalCount2',
SUM(CASE WHEN TypeId ='1' THEN 1 ELSE 0 END) AS 'TotalCount3',
SUM(CASE WHEN TypeId ='10' THEN 1 ELSE 0 END) AS 'TotalCount4',
SUM(CASE WHEN TypeId ='5' THEN 1 ELSE 0 END) AS 'TotalCount5',
SUM(CASE WHEN TypeId ='8' THEN 1 ELSE 0 END) AS 'TotalCount6'
FROM [Party]
Please refer the screenshot as the output of the above script.
What I want:
I want a column after the Total as the total number of the column having nonzero values.
Like in the picture the values should be 2 as TotalCount1 and Totalcount3 have non zero values.
SELECT COUNT(*) AS Total,
...
...
CASE ( WHEN SUM(CASE WHEN TypeId ='4' THEN 1 ELSE 0 END) > 0 THEN 1 ELSE 0 END) +
CASE ( WHEN SUM(CASE WHEN TypeId ='6' THEN 1 ELSE 0 END) > 0 THEN 1 ELSE 0 END) +
CASE ( WHEN SUM(CASE WHEN TypeId ='1' THEN 1 ELSE 0 END) > 0 THEN 1 ELSE 0 END) +
CASE ( WHEN SUM(CASE WHEN TypeId ='10' THEN 1 ELSE 0 END) > 0 THEN 1 ELSE 0 END) +
CASE ( WHEN SUM(CASE WHEN TypeId ='5' THEN 1 ELSE 0 END) > 0 THEN 1 ELSE 0 END) +
CASE ( WHEN SUM(CASE WHEN TypeId ='8' THEN 1 ELSE 0 END) > 0 THEN 1 ELSE 0 END)
as SumOfNonZeros
FROM [Party]
Or maybe simpler
SELECT COUNT(*) AS Total,
COUNT(CASE WHEN TypeId ='4' THEN 1 END) AS 'TotalCount1',
COUNT(CASE WHEN TypeId ='6' THEN 1 END) AS 'TotalCount2',
COUNT(CASE WHEN TypeId ='1' THEN 1 END) AS 'TotalCount3',
COUNT(CASE WHEN TypeId ='10' THEN 1 END) AS 'TotalCount4',
COUNT(CASE WHEN TypeId ='5' THEN 1 END) AS 'TotalCount5',
COUNT(CASE WHEN TypeId ='8' THEN 1 END) AS 'TotalCount6',
COUNT( DISTINCT CASE WHEN TypeId IN ('4', '6', '1', '10', '5', '8')
THEN TypeId
END ) as CountOfNonZeros
FROM [Party]
Using CASE expression over the selecting result, you can do this:
SELECT (
CASE WHEN TotalCount1 > 0 THEN 1 ELSE 0 END +
CASE WHEN TotalCount2 > 0 THEN 1 ELSE 0 END +
CASE WHEN TotalCount3 > 0 THEN 1 ELSE 0 END +
CASE WHEN TotalCount4 > 0 THEN 1 ELSE 0 END +
CASE WHEN TotalCount5 > 0 THEN 1 ELSE 0 END +
CASE WHEN TotalCount6 > 0 THEN 1 ELSE 0 END) AS Result
FROM (
SELECT COUNT(*) AS Total,
SUM(CASE WHEN TypeId ='4' THEN 1 ELSE 0 END) AS 'TotalCount1',
SUM(CASE WHEN TypeId ='6' THEN 1 ELSE 0 END) AS 'TotalCount2',
SUM(CASE WHEN TypeId ='1' THEN 1 ELSE 0 END) AS 'TotalCount3',
SUM(CASE WHEN TypeId ='10' THEN 1 ELSE 0 END) AS 'TotalCount4',
SUM(CASE WHEN TypeId ='5' THEN 1 ELSE 0 END) AS 'TotalCount5',
SUM(CASE WHEN TypeId ='8' THEN 1 ELSE 0 END) AS 'TotalCount6'

Is there a way to count a number of columns which has a particular value for each rows in Hive.
I have data which looks like in input and I want to count how many columns have value 'a' and how many column have value 'b' and get the output like in 'Output'.
Is there a way to accomplish this with Hive query?
One method in Hive is:
select ( (case when cl_1 = 'a' then 1 else 0 end) +
(case when cl_2 = 'a' then 1 else 0 end) +
(case when cl_3 = 'a' then 1 else 0 end) +
(case when cl_4 = 'a' then 1 else 0 end) +
(case when cl_5 = 'a' then 1 else 0 end)
) as count_a,
( (case when cl_1 = 'b' then 1 else 0 end) +
(case when cl_2 = 'b' then 1 else 0 end) +
(case when cl_3 = 'b' then 1 else 0 end) +
(case when cl_4 = 'b' then 1 else 0 end) +
(case when cl_5 = 'b' then 1 else 0 end)
) as count_b
from t;
To get the total count, I would suggest using a subquery and adding count_a and count_b.
Use lateral view with explode on the data and do the aggregations on it.
select id
,sum(cast(col='a' as int)) as cnt_a
,sum(cast(col='b' as int)) as cnt_b
,sum(cast(col in ('a','b') as int)) as cnt_total
from tbl
lateral view explode(array(ci_1,ci_2,ci_3,ci_4,ci_5)) tbl as col
group by id
SELECT
userid,
CASE
WHEN (COUNT(CASE
WHEN onlinesportsgamewagers != 0
THEN 1
ELSE null
END)
+ COUNT(CASE
WHEN depositmade_amt != 0
THEN 1
ELSE null
END)) >= 10
THEN "VIP"
ELSE "NON-VIP"
END as VIPcheck
FROM
player_activity
WHERE
userid = 2023410
GROUP BY
year(txndate), month(txndate)
This query determines the user's VIP status for each month.
Ultimately, I want to have a query that determines if the user achieved VIP status for at least 3 months (including the current month). For the time being, it's only user 2023410, but eventually I want to run this for the whole database.
Therefore my ultimate output would be:
User - VIPcheck (3 different months w/ active status)
(one row per userID)
HAVING COUNT(CASE WHEN (COUNT(CASE WHEN onlinesportsgamewagers != 0
THEN 1
ELSE null
END)
+ COUNT(CASE WHEN depositmade_amt != 0
THEN 1
ELSE null
END)) >= 10
THEN 1
ELSE 0
END)
Tried the above having statement, but it didn't work. Any suggestions?
If I understand correctly, this gets the VIP status for one user by month:
SELECT userid, year(txndate), month(txndate),
(CASE WHEN SUM(CASE WHEN onlinesportsgamewagers <> 0 THEN 1 ELSE 0 END) +
SUM(CASE WHEN depositmade_amt <> 0 THEN 1 ELSE 0 END) >= 10
THEN 'VIP'
ELSE 'NON-VIP'
END) as VIPcheck
FROM player_activity
GROUP BY userid, year(txndate), month(txndate);
Another aggregation will get what you want:
SELECT userid,
(CASE WHEN SUM(VIPcheck = 'VIP') >= 3 THEN 'SUPER-VIP'
WHEN SUM(VIPcheck = 'VIP') >= 1 THEN 'VIP'
ELSE 'HOI POLLOI'
END) as status
FROM (SELECT userid, year(txndate), month(txndate),
(CASE WHEN SUM(CASE WHEN onlinesportsgamewagers <> 0 THEN 1 ELSE 0 END) +
SUM(CASE WHEN depositmade_amt <> 0 THEN 1 ELSE 0 END) >= 10
THEN 'VIP'
ELSE 'NON-VIP'
END) as VIPcheck
FROM player_activity
GROUP BY userid, year(txndate), month(txndate)
) uym
GROUP BY userid;
Any reason why i'm getting a missing expression error?

First off, you are retrieving a COUNT from transplant_organs, but then never doing a comparison. WHERE COUNT > 0 can be removed and then with the ending parenthesis you can put ) > 0.
Second, your outer select doesn't have a FROM clause. At the very least use FROM dual.
Example:
SELECT CASE
WHEN (SELECT 1 FROM dual) > 0
THEN (SELECT 'Something' FROM dual)
END
FROM dual;
I am trying to find a better way to write this sql server code 2008. It works and data is accurate. Reason i ask is that i will be asked to do this for several other reports going forward and want to reduce the amount of code to upkeep going forward.
How can i take a field where i sum for the yes/no/- (dash) in each field without doing an individual sum as i have in code. Each table is a month of detail data which i sum using in a CTE. i changed the table name for each month and Union All to put data together. Is there a better way to do this. This is a small sample of code. Thanks for the help.
WITH H AS (
SELECT 'August' AS Month_Name
, SUM(CASE WHEN G.FFS = '-' THEN 1 ELSE 0 END) AS FFS_Dash

, SUM(CASE WHEN G.FFS = 'No' THEN 1 ELSE 0 END) AS FFS_No

, SUM(CASE WHEN G.DNA = 'No' THEN 1 ELSE 0 END) AS DNA_No
FROM table07 G )
select * from H
UNION ALL
select * from G
How about:
SELECT Month_Name,
SUM(CASE WHEN G.FFS = '-' THEN 1 ELSE 0 END) AS FFS_Dash,
SUM(CASE WHEN G.FFS = 'Yes' THEN 1 ELSE 0 END) AS FFS_Yes,
SUM(CASE WHEN G.FFS = 'No' THEN 1 ELSE 0 END) AS FFS_No,
SUM(CASE WHEN G.DNA = '-' THEN 1 ELSE 0 END) AS DNA_Dash,
SUM(CASE WHEN G.DNA = 'Yes' THEN 1 ELSE 0 END) AS DNA_Yes,
SUM(CASE WHEN G.DNA = 'No' THEN 1 ELSE 0 END) AS DNA_No
FROM ((select 'July' as Month_Name, G.*
from table07 G
) union all
(select 'August', H.*
from table08 H
)
) gh
GROUP BY Month_Name;
However, having tables with the same structure is usually a sign of poor database design. You should have a single table with a column representing the month.
