I'm trying to have this result :
Those two lines are from the same query, but I must duplicate the result (first called "CLI" and second "CPA").
Currently I do it with an UNION :
WITH Temp AS (SELECT Code, Name, ...)
SELECT 'CLI' as RecordType, Code, Name, CONCAT('CLI', Name) as TechnicalName, ... FROM Temp
UNION ALL
SELECT 'CPA' as RecordType, Code, Name, CONCAT('CPA', Name) as TechnicalName, ... FROM Temp
Is there any other solution most efficient ?
Because there are about 30 columns, so the code is very big now.
I thought of something like this :
DECLARE #P_RecordType as char(3);
WITH Temp AS (SELECT Code, Name, ...)
SET #P_RecordType = 'CLI'
SELECT * FROM Temp
UNION ALL
SET #P_RecordType = 'CPA'
SELECT * FROM Temp
But it doesn't work.
PS: I'm querying on SSMS from "Microsoft SQL Azure (RTM) - 12.0.2000.8".
You can try to use CROSS APPLY with value to make it simple.
Query 1:
SELECT v.c as RecordType, Code, Name, CONCAT(v.c, Name) as TechnicalName
FROM Temp
CROSS APPLY(VALUES ('CPA'),('CLI')) v (c)

I need some support with array type, because it is a new thing for me, so
I have a function:
create or replace type num_array as table of number;
create or replace function functionname(arr_in num_array)
return num_array is
tab num_array;
begin
select id_acc bulk collect into tab from (
SELECT a.id_acc
FROM (SELECT id_acc, parent_acc FROM account) a
connect by nocycle prior a.id_acc=a.parent_acc
start with id_acc in
(
select distinct ID_ACC
from (SELECT id_acc, parent_acc FROM account
) a
where parent_acc = id_acc
connect by nocycle prior a.parent_acc = a.id_acc or parent_acc is null
start with id_acc in (select parent_acc from table_name t,account a where t.id=a.id_acc)));
return tab;
end;
As an input I want to have an array of numbers (id). I want to connect that number (from input) with account table. It is in line:
start with id_acc in (select parent_acc from table_name t,account a where t.id=a.id_acc)));
I would like to join somehow table account with numbers from input,
I was trying to use table(tab()),account a but I got an error.
As output I would like to have result of select query so (return tab).
I'm not sure I understood what you want to achieve. Just to help you with the syntax, look at this:
start with id_acc in (select * from table(arr_in));
Below i have provided a small snippet which basically illustrates your issue with joining Nested Table type with Table.
CREATE OR REPLACE FUNCTION test_ntt_join
RETURN NUMBER_NTT
AS
lv_tab_num NUMBER_NTT;
lv_tab2 NUMBER_NTT;
BEGIN
SELECT LEVEL BULK COLLECT INTO lv_tab_num FROM DUAL CONNECT BY LEVEL < 10;
SELECT COLUMN_VALUE
BULK COLLECT INTO
lv_tab2
FROM TABLE(lv_tab_num) t,
EMP
WHERE emp.empno= t.column_value;
RETURN lv_tab2;
END;
------------------------------------------OUTPUT------------------------------------
select * from table(test_ntt_join);
COLUMN_VALUE
1
1
3

I want to do a nested aggregation, is this possible? SQL Server 2012 is returning an error when I try to do the following:
SELECT SUM(COUNT(memberID)) FROM table
The situation I have is the following:
I have members who have the same member ids as their dependents in the same table. I want to get the count of the the members and their dependents based on the memberID, however, I want the count in a column next to the main enrollee which is identified by another column as an e.
SELECT memberID, memberName, COUNT(memberID)
FROM table
WHERE memberRole = 'e'
The above would return 1 for all results, so I was thinking if I count the memberIds, then sum them would work but that returned an error, Am I doing something wrong? What is the best way to reach this porblem
Your original query was correct, with a slight change:
SELECT MemberID, MemberName, (SELECT COUNT(MemberID) FROM table WHERE MemberID = M.MemberID GROUP BY MemberID) AS MemberCount
FROM table M
WHERE M.MemberRole = 'E'
try this:
SELECT memberID, memberName, Sum(CNT) From
(
SELECT memberID, memberName, COUNT(memberID) CNt
FROM table
WHERE memberRole = 'e'
) t
group by memberID, memberName
I have a table Emp like this for example.
----------------------
eName | eId

Say i am looking for an entry whose id is 3.I want to write a query which finds the row and displays it.But if it doesnt find it it is expected to display a default row (temp,999)
select case
when (total != 0) then (select eName from Emp where eId = 3)
when (total == 0) then "temp"
end as eName,
case
when (total != 0) then (select eId from Emp where eId = 3)
when (total == 0) then 999
end as eId
from Emp,(select count(*) as total from Emp where eId = 3);
Using this query that i wrote it gives me two rows as a result.
temp 999
temp 999
I assume it is because of
(select count(*) as total from Emp where eId = 3) this query in the from list of the query.
I tried using the distinct clause and it gives me just a single row. But i am a little doubtful if i am messing the query and only trying to probably employ a hack to do it.Please suggest if there is a better way to do this or if i am wrong.
I'll get to how to do this right, but first let me give you a long answer to maybe help you with your understanding of SQL. What's happening to use is this:
Your select clause does not affect the number of records you get. So to understand what's happenning, let's simpify the query a little. Let's change it to,
select * from emp, (select count(*) as total from emp where eid=3)
I'm not sure what you think the comma after "emp" does here, but SQL see this as an old-style join on two tables: emp and the temporary table created by the select count(*), etc. There is no WHERE clause, so this is a cross join, but the second table only has one record anyway, so that part doesn't matter. But the fact that there is no WHERE clause means that you will get every record in emp, joined to the count. So the output of this query is:
ename eid count(*)
Anusha 1 0
Sunny 2 0
If you had 100 records, you would get 100 results.
Frankly there is no really clean way to do what you want in SQL. It's the sort of thing that's cleaner to do in code: do a plain "select ... where eid=3", and if you get no records, fill in the default at run-time.
But assuming that you need to do it in SQL for some reason, I think the simplest way would be:
select eid, ename from emp where eid=3
union
select 999 as eid, 'temp' as ename
where not exists (select 1 from emp where eid=3)
In some versions of SQL you need to give a dummy table name on the second select, like Oracle requires you to say "from dual".
When I execute my "select union select", I get the correct number or rows (156)
Executed independently, select #1 returns 65 rows and select #2 returns 138 rows.
When I use this "select union select" with an Insert into, I get 203 rows (65+138) with duplicates.
I would like to know if it is my code structure that is causing this issue ?
INSERT INTO dpapm_MediaObjectValidation (mediaobject_id, username, checked_date, expiration_date, notified)
(SELECT FKMediaObjectId, CreatedBy,#checkdate,dateadd(ww,2,#checkdate),0
FROM dbo.gs_MediaObjectMetadata
LEFT JOIN gs_MediaObject mo
ON gs_MediaObjectMetadata.FKMediaObjectId = mo.MediaObjectId
WHERE UPPER([Description]) IN ('CAPTION','TITLE','AUTHOR','DATE PHOTO TAKEN','KEYWORDS')
AND FKMediaObjectId >=
(SELECT TOP 1 MediaObjectId
FROM dbo.gs_MediaObject
WHERE DateAdded > #lastcheck
ORDER BY MediaObjectId)
GROUP BY FKMediaObjectId, CreatedBy
HAVING count(*) < 5
UNION
SELECT FKMediaObjectId, CreatedBy,getdate(),dateadd(ww,2,getdate()),0
FROM gs_MediaObjectMetadata yt
LEFT JOIN gs_MediaObject mo
ON yt.FKMediaObjectId = mo.MediaObjectId
WHERE UPPER([Description]) = 'KEYWORDS'
AND FKMediaObjectId >=
(SELECT TOP 1 MediaObjectId
FROM dbo.gs_MediaObject
WHERE DateAdded > #lastcheck
ORDER BY MediaObjectId)
AND NOT EXISTS
(
SELECT *
FROM dbo.fnSplit(Replace(yt.Value, '''', ''''''), ',') split
WHERE split.item in (SELECT KeywordEn FROM gs_Keywords) or split.item in (SELECT KeywordFr FROM gs_Keywords)
)
)
I would appreciate any clues into resolving this problem ...
Thank you !
The UNION keyword should only return distinct records between the two queries. However, if I recall correctly, this is only true if the datatypes are the same. The date variables might be throwing that off. Depending on the collation type, whitespace might be handled differently as well. You might want to do a SELECT DISTINCT on the dpapm_MediaObjectValidation table after doing your insert, but be sure to trim whitespace from both sides in your comparison. Another approach is to do your first insert, then on your second insert, forgo the UNION altogether and do a manual EXISTS check to see if the items to be inserted already exist.
Is it possible to access a temporary column that was defined in a query for a Common Table Expression? Say I have
select * from myTable
;with cte as
(
select
*, Salary * 4 as FourTimesSalary
from
Employees
where
Name = #name
and ID >= 100
)
Is there a way to use the temporary column FourTimesSalary when querying cte like so?
select top 2 *
from cte
order by FourTimesSalary, Name
TIA.
Yes you can do that. Example:
with temp as
(
select 1 as id, 2*4 as val
UNION
select 2 as id, 3*4 as val
)
SELECT * FROM temp ORDER BY VAL desc
Your example looks fine, did you get an error when you tried that or something?
