I am running flink sql in flink version 1.12.0 and batch mode,
select app_id, count(case cnt when 1 then 1 end ), count(case cnt > 1 then 1 end ) from xxx
get result below:
xception in thread "main" org.apache.flink.table.api.SqlParserException: SQL parse failed. Encountered "then" at line 1, column 72.
Looks like you missed when keyword in your SQL, the syntax should be:case when condition then ... end.
select app_id, count(case cnt when 1 then 1 end ), count(case when cnt > 1 then 1 end ) from xxx

I have a rollup SQL statement that I'm trying to covert over from Oracle into PostGresSql. Overall the results look correct except I'm getting a blank value in the grouping column and I'm not sure how to get rid of it.
Right now I have:
SELECT
COALESCE(CASE WHEN GROUPING(COUNTY) = 1 THEN 'TOTAL' else county::text END) as COUNTY
,COUNT(CASE WHEN STV_TO_GAS THEN 1 END) as STOVE_TO_GAS_SUM
,COUNT(CASE WHEN FIRE_TO_GAS THEN 1 END) as FIRE_TO_GAS_SUM
,COUNT(CASE WHEN PELLET_TO_GAS THEN 1 END) as PELLET_TO_GAS_SUM
,COUNT(CASE WHEN STV_TO_ELECTRIC THEN 1 END) as STOVE_TO_ELECTRIC_SUM
,COUNT(CASE WHEN FIRE_TO_ELECTRIC THEN 1 END) as FIRE_TO_ELECTRIC_SUM
,COUNT(CASE WHEN PELLET_TO_ELECTRIC THEN 1 END) as PELLET_TO_ELECTRIC_SUM
,COUNT(CASE WHEN MERIDIAN THEN 1 END) as WITHIN_MERIDIAN_SUM
,count(CASE WHEN hb357.stv_to_gas then 1 END) +
count(CASE WHEN hb357.fire_to_gas then 1 END) +
count(CASE WHEN hb357.pellet_to_gas then 1 END) +
count(CASE WHEN hb357.stv_to_electric then 1 END) +
count(CASE WHEN hb357.fire_to_electric then 1 END) +
count(CASE WHEN hb357.pellet_to_electric then 1 END) +
count(CASE WHEN hb357.meridian then 1 END ) AS county_totals
FROM woodburn.HB357
WHERE app_status IN ('pending','approved')
AND (COUNTY IS NOT NULL OR trim(COUNTY) <> '')
GROUP BY rollup (county)
but its still returning a blank value in the county column
I've also trued changing the first case statement to
COALESCE(CASE
WHEN GROUPING(COUNTY) = 1 THEN 'TOTAL'
WHEN TRIM(COUNTY) != '' AND COUNTY IS NOT NULL then county
END) as COUNTY
but its returning a null row for county
FINAL SOLUTION
After trying all things suggested I essentially implemented what Jorge Campos recommended by doing the following:
SELECT
COALESCE(CASE
WHEN GROUPING(COUNTY) = 1 THEN 'TOTAL'
WHEN TRIM(COUNTY) != '' then county
END) as COUNTY
,COUNT(CASE WHEN STV_TO_GAS THEN 1 END) as STOVE_TO_GAS_SUM
,COUNT(CASE WHEN FIRE_TO_GAS THEN 1 END) as FIRE_TO_GAS_SUM
,COUNT(CASE WHEN PELLET_TO_GAS THEN 1 END) as PELLET_TO_GAS_SUM
,COUNT(CASE WHEN STV_TO_ELECTRIC THEN 1 END) as STOVE_TO_ELECTRIC_SUM
,COUNT(CASE WHEN FIRE_TO_ELECTRIC THEN 1 END) as FIRE_TO_ELECTRIC_SUM
,COUNT(CASE WHEN PELLET_TO_ELECTRIC THEN 1 END) as PELLET_TO_ELECTRIC_SUM
,COUNT(CASE WHEN MERIDIAN THEN 1 END) as WITHIN_MERIDIAN_SUM
,count(CASE WHEN hb357.stv_to_gas then 1 END) +
count(CASE WHEN hb357.fire_to_gas then 1 END) +
count(CASE WHEN hb357.pellet_to_gas then 1 END) +
count(CASE WHEN hb357.stv_to_electric then 1 END) +
count(CASE WHEN hb357.fire_to_electric then 1 END) +
count(CASE WHEN hb357.pellet_to_electric then 1 END) +
count(CASE WHEN hb357.meridian then 1 END ) AS county_totals
FROM woodburn.HB357
WHERE app_status IN ('pending','approved')
AND COUNTY IS NOT NULL
AND TRIM(COUNTY) != ''
GROUP BY rollup (county)
I am counting the size of my teams within a department. All employees have an employee ID beginning with "E" and then a designating number (i.e. "0", "1", etc) to denote which team they are on.
I have the following query in Postgres to count the size of the teams, but the problem is that with this query, I get a lot of rows that are empty, because some months are duplicated. For example, the row containing "May/2016" may be duplicated 3 times, with only 1 row containing the actual team counts.
select to_char("Date", 'Mon/YYYY') as "Date",
sum(case when l_part LIKE 'E0%%' then count end) as "ACCOUNTING",
sum(case when l_part LIKE 'E1%%' then count end) as "SW",
sum(case when l_part LIKE 'E2%%' then count end) as "SUPPORT",
sum(case when l_part LIKE 'E3%%' then count end) as "CALLCENTER",
sum(case when l_part LIKE 'E4%%' then count end) as "ADMIN",
sum(case when l_part LIKE 'E5%%' then count end) as "MARKETING",
sum(case when l_part LIKE 'E9%%' then count end) as "MANAGEMENT"
from (
select left("Type",4)as l_part, count(*),"Date" from
"Transactions" group by "Date",l_part
) p group by "Date"
order by min("Date");
If I can just get the count down to one row per month/yyyy, and order by the date that would be helpful and less confusing. Any tweaks to my attempt appreciated.
Here is what populates, as an example using September 2015:
This is what I get:
DATE | ACCOUNTING | SW | SUPPORT | CALLCENTER | ADMIN | MARKETING |
Sep/15| | | | | | |
Sep/15| | | | | | |
Sep/15| 1 | 2 | 1 | 5 | 5 | 3 |
I suspect your issue is the GROUP BY clause, which I think is solved using DATE_TRUNC(). Not sure if you need the where clause.
SELECT
to_char(DATE_TRUNC('month',"Date"), 'Mon/YYYY') as "Date"
, SUM(CASE WHEN left("Type",4) LIKE 'E0%%' THEN 1 END) AS "ACCOUNTING"
, SUM(CASE WHEN left("Type",4) LIKE 'E1%%' THEN 1 END) AS "SW"
, SUM(CASE WHEN left("Type",4) LIKE 'E2%%' THEN 1 END) AS "SUPPORT"
, SUM(CASE WHEN left("Type",4) LIKE 'E3%%' THEN 1 END) AS "CALLCENTER"
, SUM(CASE WHEN left("Type",4) LIKE 'E4%%' THEN 1 END) AS "ADMIN"
, SUM(CASE WHEN left("Type",4) LIKE 'E5%%' THEN 1 END) AS "MARKETING"
, SUM(CASE WHEN left("Type",4) LIKE 'E9%%' THEN 1 END) AS "MANAGEMENT"
FROM "Transactions"
WHERE "Date" IS NOT NULL
GROUP BY
DATE_TRUNC('month',"Date")
ORDER BY
DATE_TRUNC('month',"Date")
btw: Instead of SUM() an alternatve using COUNT() would be:
SELECT
to_char(DATE_TRUNC('month',"Date"), 'Mon/YYYY') as "Date"
, COUNT(CASE WHEN left("Type",4) LIKE 'E0%%' THEN 1 END) AS "ACCOUNTING"
, COUNT(CASE WHEN left("Type",4) LIKE 'E1%%' THEN 1 END) AS "SW"
, COUNT(CASE WHEN left("Type",4) LIKE 'E2%%' THEN 1 END) AS "SUPPORT"
, COUNT(CASE WHEN left("Type",4) LIKE 'E3%%' THEN 1 END) AS "CALLCENTER"
, COUNT(CASE WHEN left("Type",4) LIKE 'E4%%' THEN 1 END) AS "ADMIN"
, COUNT(CASE WHEN left("Type",4) LIKE 'E5%%' THEN 1 END) AS "MARKETING"
, COUNT(CASE WHEN left("Type",4) LIKE 'E9%%' THEN 1 END) AS "MANAGEMENT"
COUNT() increments by one for any NON-NULL value it encounters.
This query works in data studio, but fails to show alias in MS Query!
I have tried different types such as "",'',[] and even https://support.microsoft.com/en-us/kb/298955
SELECT 'TRANIN'AS NAME, SUM(CASE WHEN ALT3.TRANINDT BETWEEN 20150603 AND 20150601 THEN 1 else 0 END) AS CurrentMonth, SUM(CASE WHEN ALT3.TRANINDT BETWEEN 20150501 AND 20150531 THEN 1 else 0 END) AS LastMonth
FROM ALT3
MS broke MS query a long time ago...
I've tried to get it to work right, but nothing worked. I've pretty much given up.
Normally I just rename the column once the data is back in Excel.
But if you really want the name returned from MS query, this works:
WITH tbl AS (SELECT 'TRANIN'AS NAME
, SUM(CASE WHEN ALT3.TRANINDT BETWEEN 20150603 AND 20150601
THEN 1 else 0 END) AS CurrentMonth
, SUM(CASE WHEN ALT3.TRANINDT BETWEEN 20150501 AND 20150531
THEN 1 else 0 END) AS LastMonth
FROM ALT3)
SELECT * FROM TBL
Good Day Everyone!
well i have this kind of code and it kinda ugly,
a friend of mine told me i can implement Case Statements in here, but i do not know how or how would i implement, the code is long so if you could just help me to optimize my code i would appreciate it greatly!
PS. please be gentle to me, im new in T-sql :)
Thank yoU!

Assuming your data is bit like this Sql Fiddle Example, try this for the sub query using SUM() and CASE.
SELECT SUM(CASE WHEN fld_StorageGroupID >= 3 and fld_StorageGroupID <= 14 ELSE 0 END) Col1And4,
SUM(CASE WHEN fld_StorageGroupID = 1 THEN 1 ELSE 0 END) Col2And5,
SUM(CASE WHEN fld_StorageGroupID = 2 THEN 1 ELSE 0 END) Col3And6
FROM #TEMPTABLE1
GROUP BY fld_StorageGroupID
Since you are applying the same filter for last 3 columns in the subquery, I have done only first 3 columns here.
EDIT:
I think this is better than above (Note: no need to use SUM() in the main query).
Fiddle Example with data
select col1_4 CY_Jewelry,
col2_5 CY_Appliance,
col3_6 CY_Cellphone,
col1_4 PY_Jewelry,
col2_5 PY_Appliance,
col3_6 PY_Cellphone
from (
select sum(case when id>= 3 and id <= 14 then 1 else 0 end) col1_4,
sum(case when id = 2 then 1 else 0 end) col2_5,
sum(case when id = 3 then 1 else 0 end) col3_6
from t
--group by id
) X
I have a T-SQL query that I need to total out the counts for the CASE statements.
I tried to add a UNION but I am getting an error:
All queries in an SQL statement containing a UNION operator must have
an equal number of expressions in their target lists.
Any ideas? Thanks.
Query:
SELECT
CustomerID, Name, DueDate,
CASE WHEN DATEDIFF(Month, PaymentDate, DueDate) >= 1
THEN PaymentAmount ELSE 0
END AS [Early],
CASE WHEN DATEDIFF(Month, PaymentDate, DueDate) >=0
THEN PaymentAmount ELSE 0
END AS [On Time],
CASE WHEN DATEDIFF(Month, PaymentDate, DueDate) = -1
THEN PaymentAmount ELSE 0
END AS [Late]
FROM
Customers
WHERE
DATEDIFF(MONTH, PaymentDate,DueDate), GetDate()) = 1
AND PaymentAmount= DuesAmount
UNION
SELECT
'-Total', '', CustomerID, Name, DueDate,
SUM(CASE WHEN DATEDIFF(Month, PaymentDate, DueDate) >= 1
THEN PaymentAmount ELSE 0 END) AS [Early],
SUM(CASE WHEN DATEDIFF(Month, PaymentDate, DueDate) >= 0
THEN PaymentAmount ELSE 0 END) AS [On Time],
SUM(CASE WHEN DATEDIFF(Month, PaymentDate, DueDate) = -1
THEN PaymentAmount ELSE 0 END) AS [Late]
FROM
Customers
WHERE
DATEDIFF(MONTH, PaymentDate,DueDate), GetDate()) = 1
AND PaymentAmount = DuesAmount
The error says, "All queries in a SQL statement containing a UNION operator must have an equal number of expressions in their target lists." What this means is that each SELECT must return the same number of expressions.
In the code sample you gave us, the first SELECT statement returns 6 expressions, while the second one returns 8:
SELECT CustomerID, -- 1
Name, -- 2
DueDate, -- 3
CASE ... END AS [Early], -- 4
CASE ... END AS [On Time], -- 5
CASE ... END AS [Late] -- 6
...
UNION
SELECT '-Total', -- 1
'', -- 2
CustomerID, -- 3
Name, -- 4
DueDate, -- 5
SUM(CASE ... END) AS [Early], -- 6
SUM(CASE ... END) AS [On Time], -- 7
SUM(CASE ... END) AS [Late] -- 8
...
See how the first SELECT returns 6 expressions, but the second returns 8? In a UNION, all the SELECT statements must return the same number of expressions.
You can return NULL in the first query for columns that don't have a match in the second, if necessary. For example:
SELECT NULL as [RowType], -- 1
NULL as [Padding], -- 2
CustomerID, -- 3
Name, -- 4
DueDate, -- 5
CASE ... END AS [Early], -- 6
CASE ... END AS [On Time], -- 7
CASE ... END AS [Late] -- 8
...
UNION
SELECT '-Total', -- 1
'', -- 2
CustomerID, -- 3
Name, -- 4
DueDate, -- 5
SUM(CASE ... END) AS [Early], -- 6
SUM(CASE ... END) AS [On Time], -- 7
SUM(CASE ... END) AS [Late] -- 8
...
Also, note that you don't have a comma after the DueDate column.
