I am trying to pull data out and chuck it into a Stimulsoft report. The problem I am having is that I need it to output to two columns. I also need every "manager" record to show even if the count assigned to said record is NULL.
This is what i have at the moment:
DECLARE #ManagerCount INT = (( SELECT Count(*) FROM AM WHERE dbo.AM.AMCurrent = 1 AND dbo.AM.OmitInReport = 0 ) + 1) / 2
DECLARE #tmp_AM1 TABLE (AMID INT, AMName NVARCHAR(100), ID INT)
INSERT INTO #tmp_AM1 SELECT AMID, AMName, row_number() over (order by AMID ) FROM AM
WHERE dbo.AM.AMCurrent = 1 AND dbo.AM.OmitInReport = 0
SELECT * FROM (
SELECT ta.id AS id1, ta.AMName AS ManagerName1, COUNT(*) AS ManagerCount1 FROM #tmp_AM1 tA INNER JOIN Job J ON tA.AMID = j.AMID
WHERE ta.ID BETWEEN 1 AND #ManagerCount AND j.jobStatusID != 5
GROUP BY ta.ID, ta.AMName
) a
LEFT JOIN
(
SELECT ta.id AS id2,ta.AMName AS ManagerName2, COUNT(*) AS ManagerCount2 FROM #tmp_AM1 tA INNER JOIN Job J ON tA.AMID = j.AMID
WHERE ta.ID > #ManagerCount AND j.jobStatusID != 5
GROUP BY ta.AMName, ta.ID
) b ON a.id1 + #ManagerCount = b.id2
Which ends up returning something like:
There are 18 managers so 9 per column, but this code doesn't show them all since anything that doesn't have a count in the first left join, won't show, and therefore the same row in column 2 doesn't show.
Results of SELECT * FROM #tmp_AM1:
DECLARE #tmp_AM1 TABLE (AMID INT, AMName NVARCHAR(100), ID INT)
INSERT INTO #tmp_AM1 SELECT AMID, AMName, row_number() over (order by AMID ) FROM AM
WHERE dbo.AM.AMCurrent = 1 AND dbo.AM.OmitInReport = 0
SELECT * FROM (
SELECT ta.id AS id1, ta.AMName AS ManagerName1, COUNT(*) AS ManagerCount1 FROM #tmp_AM1 tA INNER JOIN Job J ON tA.AMID = j.AMID
WHERE ta.ID BETWEEN 1 AND #ManagerCount AND j.jobStatusID != 5
GROUP BY ta.ID, ta.AMName
) a
LEFT OUTER JOIN
(
SELECT ta.id AS id2,ta.AMName AS ManagerName2, COUNT(*) AS ManagerCount2 FROM #tmp_AM1 tA INNER JOIN Job J ON tA.AMID = j.AMID
WHERE ta.ID > #ManagerCount AND j.jobStatusID != 5
GROUP BY ta.AMName, ta.ID
) b ON a.id1 + #ManagerCount = b.id2 where ManagerName2 IS Null and ManagerCount2 IS NULL
just you want to use LEFT OUTER JOIN for select row even there is have any null values.,
Since the two subqueries are pretty much identical, except the where-statement, I would consiter rewriting it into one single query. I'm not sure why you need the same columns outputed into different columns in the result, but something like this might work:
WITH cte AS (
SELECT
ta.id AS id
,ta.AMName AS ManagerName
,COUNT(*) AS ManagerCount
,CASE WHEN ta.ID BETWEEN 1 AND #ManagerCount THEN 0 ELSE 1 END AS something
FROM
#tmp_AM1 tA
INNER JOIN Job J ON tA.AMID = j.AMID
WHERE
j.jobStatusID != 5
GROUP BY
ta.ID
,ta.AMName
,CASE WHEN ta.ID BETWEEN 1 AND #ManagerCount THEN 0 ELSE 1 END
)
SELECT
CASE WHEN something = 0 THEN cte.id ELSE null END AS id1
,CASE WHEN something = 0 THEN cte.ManagerName ELSE null END AS ManagerName1
,CASE WHEN something = 0 THEN cte.ManagerCount ELSE null END AS ManagerCount1
,CASE WHEN something = 1 THEN cte.id ELSE null END AS id2
,CASE WHEN something = 1 THEN cte.ManagerName ELSE null END AS ManagerName2
,CASE WHEN something = 1 THEN cte.ManagerCount ELSE null END AS ManagerCount2
FROM
cte
Probably not the best approach but i got the correct output using:
DECLARE #ManagerCount INT = (( SELECT Count(*) FROM AM WHERE dbo.AM.AMCurrent = 1 AND dbo.AM.OmitInReport = 0 ) + 1) / 2
DECLARE #tmp_AM1 TABLE (AMID INT, AMName NVARCHAR(100), ID INT)
INSERT INTO #tmp_AM1 SELECT AMID, AMName, row_number() over (order by AMID ) FROM AM
WHERE dbo.AM.AMCurrent = 1 AND dbo.AM.OmitInReport = 0
ORDER By AMName
SELECT ManagerName1, ManagerName2, ManagerCount1, ManagerCount2 FROM (
SELECT AMID, ta.id AS id1, ta.AMName AS ManagerName1 FROM #tmp_AM1 tA
WHERE (ta.ID BETWEEN 1 AND #ManagerCount)
) a
LEFT JOIN
(
SELECT AMID, ISNULL(COUNT(*), 0) AS ManagerCount1 FROM Job j
INNER JOIN tblJobOutcome jO ON j.JobOutcomeID = jo.JobOutcomeID AND jO.JobOutcomeID != 5
GROUP BY AMID
) a1 ON a.AMID = a1.AMID
LEFT JOIN
(
SELECT AMID, ta.id AS id2, ta.AMName AS ManagerName2 FROM #tmp_AM1 tA
WHERE (ta.ID > #ManagerCount)
) b ON a.id1 + #ManagerCount = b.id2
LEFT JOIN
(
SELECT AMID, ISNULL(COUNT(*), 0) AS ManagerCount2 FROM Job j
INNER JOIN tblJobOutcome jO ON j.JobOutcomeID = jo.JobOutcomeID AND jO.JobOutcomeID != 5
GROUP BY AMID
) b1 ON b.AMID = b1.AMID
Gives me the correct output in two columns.
gives me this:
I have procedure like this and I get error in If clause. I think it is because COUNT. But my clause have to be like that so I don't know how to solve it. Maybe it would be good to create a function or something similar. Rest of the code is okay

I am sorry for too much code but without it I can't run query.
It looks like you're trying to tell SQL Server to join to VezaUgovorUstrojstvenaJedinica differently depending on the circumstances. The sql engine can't figure that out. For a very brief discussion on how sql evaluates a query, here's a start:

Background
When dropping (or replacing) objects in PostgreSQL, if there are dependencies, the drop will fail (without specifying CASCADE).
Problem
The error message returned by the database does not list the dependent objects.
Example Solution
The query might look something like:
SELECT * FROM information_schema i, pg_depend pd WHERE
i.object_id = pd.object_id AND
i.object_type = 'TABLE' AND
i.object_schema = 'public' AND
i.object_name = 'table_with_dependents';
The objid is missing.

Question
How do you generate a list of dependent objects by name and type?
The suggested solution didn't work for me with postgresql 9.1.4
this worked:
SELECT dependent_ns.nspname as dependent_schema
, dependent_view.relname as dependent_view
, source_ns.nspname as source_schema
, source_table.relname as source_table
, pg_attribute.attname as column_name
FROM pg_depend
JOIN pg_rewrite ON pg_depend.objid = pg_rewrite.oid
JOIN pg_class as dependent_view ON pg_rewrite.ev_class = dependent_view.oid
JOIN pg_class as source_table ON pg_depend.refobjid = source_table.oid
JOIN pg_attribute ON pg_depend.refobjid = pg_attribute.attrelid
AND pg_depend.refobjsubid = pg_attribute.attnum
JOIN pg_namespace dependent_ns ON dependent_ns.oid = dependent_view.relnamespace
JOIN pg_namespace source_ns ON source_ns.oid = source_table.relnamespace
WHERE
source_ns.nspname = 'my_schema'
AND source_table.relname = 'my_table'
AND pg_attribute.attnum > 0
AND pg_attribute.attname = 'my_column'
ORDER BY 1,2;
The easy way is:
BEGIN;
DROP TABLE tablename CASCADE;
DROP VIEW viewname CASCADE;
ROLLBACK;
For PostgreSQL 9.3 onward use the following view and functions to show any user object dependency. I also updated https://wiki.postgresql.org/wiki/Pg_depend_display.
/**** Usage Examples ****
-- Examine the entire object hierarchy
SELECT report.dependency_tree('');
-- Dependencies for any relations with names containing match (in regular expression)
SELECT report.dependency_tree('match');

-- Dependencies for function slice
SELECT report.dependency_tree(ARRAY['slice'::regproc]);
-- Dependencies for type hstore
SELECT report.dependency_tree(ARRAY['hstore'::regtype]);
-- Dependencies for triggers by the name updated

If you care about specific table attributes add this to the top portion of the recursive CTE:
JOIN pg_attribute ON pg_depend.refobjid = pg_attribute.attrelid
AND pg_depend.refobjsubid = pg_attribute.attnum
...
WHERE
source_ns.nspname = 'my_schema'
AND source_table.relname = 'my_table'
AND pg_attribute.attnum > 0
AND pg_attribute.attname = 'my_column'
pg_constraint contains all constrains in the database you can list the oid of dependent tables using confrelid and conrelid from all all the foreign key constraints
query looks like this
select confrelid,conrelid from pg_constraint where contype='f';
I am trying to develop a T-SQL query to exclude all rows from another table "B". This other table "B" has 3 columns comprising its PK for a total of 136 rows. So I want to select all columns from table "A" minus those from table "B". How do I do this? I don't think this query is correct because I am still getting a duplicate record error:

Just so you know, take a look at Select all rows from one table that don't exist in another table
Basically there are at least 5 ways to select all rows from onr table that are not in another table
NOT IN
NOT EXISTS
LEFT and RIGHT JOIN
OUTER APLY (2005+)
EXCEPT (2005+)
Here is a general solution for the difference operation using left join:
select * from FirstTable
left join SecondTable on FirstTable.ID = SecondTable.ID
where SecondTable.ID is null
Of course yours would have a more complicated join on clause, but the basic operation is the same.
I think you can use "NOT IN" with a subquery, but you say you have a multi-field key?
I'd be thinking about using a left outer join and then testing for null on the right...

I have the following stored procedure which returns A, B, and the count in descending order. I am trying to use ROW_NUMBER, so I can page the records, but I want the first row number 1 to be the record with the highest count, so basically, if I return a table with 3 records and the count is 30, 20, 10, then row number 1 should correspond with count 30, row number 2 should correspond with count 20, and row number 3 should correspond with count 10. dbo.f_GetCount is a function that returns a count.
create procedure dbo.Test
as
#A nvarchar(300) = NULL,
#B nvarchar(10) = NULL
as
select #A = nullif(#A,'')
,#B = nullif(#B,'');
select h.A
,hrl.B
,dbo.f_GetCount(hrl.A,h.B) as cnt
from dbo.hrl
inner join dbo.h
on h.C = hrl.C
where(#A is null
or h.A like '%'+#A+'%'
)
and (#B is null
or hrl.B = #B
)
group by hrl.B
,h.A
order by cnt desc;
WITH q AS
(
SELECT h.A, hrl.B,
dbo.f_GetCount(hrl.A,h.B) as cnt
FROM dbo.hrl
INNER JOIN dbo.h on h.C = hrl.C
WHERE (#A IS NULL OR h.A like '%' + #A + '%')
AND (#B IS NULL OR hrl.B = #B)
GROUP BY hrl.B, h.A
)
SELECT q.*, ROW_NUMBER() OVER (ORDER BY cnt DESC) AS rn
FROM q
ORDER BY rn DESC
To retrieve first 10 rows, use:
WITH q AS
(
SELECT h.A, hrl.B,
dbo.f_GetCount(hrl.A,h.B) as cnt
FROM dbo.hrl
INNER JOIN dbo.h on h.C = hrl.C
WHERE (#A IS NULL OR h.A like '%' + #A + '%')
AND (#B IS NULL OR hrl.B = #B)
GROUP BY hrl.B, h.A
)
SELECT TOP 10 q.*,
ROW_NUMBER() OVER (ORDER BY cnt DESC, A, B) AS rn
FROM q
ORDER BY cnt DESC, A, B
To retrieve rows between 11 and 20, use:
SELECT *
FROM (
WITH q AS
(
SELECT h.A, hrl.B,
dbo.f_GetCount(hrl.A,h.B) as cnt
FROM dbo.hrl
INNER JOIN dbo.h on h.C = hrl.C
WHERE (#A IS NULL OR h.A like '%' + #A + '%')
AND (#B IS NULL OR hrl.B = #B)
GROUP BY hrl.B, h.A
)
SELECT q.*,
ROW_NUMBER() OVER (ORDER BY cnt DESC, A, B) AS rn
FROM q
) qq
WHERE rn BETWEEN 11 AND 20
ORDER BY cnt DESC, A, B
I would use a sub-query to get the values of the function into the result, and then the ROW_NUMBER ranking function, like so:
select
ROW_NUMBER() over (order by t.cnt desc) as RowId, t.*
from
(
SELECT
h.A, hrl.B, dbo.f_GetCount(hrl.A,h.B) as cnt
FROM
dbo.hrl
INNER JOIN dbo.h on h.C = hrl.C
WHERE
(#A IS NULL OR h.A like '%' + #A + '%') AND
(#B IS NULL OR hrl.B = #B)
GROUP BY
hrl.B, h.A
) as t
order by
1
If you wanted only a certain section of results (say, for paging), then you would need another subquery, and then filter on the row number:
select
t.*
from
(
select
ROW_NUMBER() over (order by t.cnt desc) as RowId, t.*
from
(
SELECT
h.A, hrl.B, dbo.f_GetCount(hrl.A,h.B) as cnt
FROM
dbo.hrl
INNER JOIN dbo.h on h.C = hrl.C
WHERE
(#A IS NULL OR h.A like '%' + #A + '%') AND
(#B IS NULL OR hrl.B = #B)
GROUP BY
hrl.B, h.A
) as t
) as t
where
t.RowId between 1 and 10
order by
t.RowId
Note that in this query, you could put ROW_NUMBER anywhere in the select list, since you are no longer reliant on using the "order by 1" syntax for the order by statement.
There is a subtle issue here when calling this query multiple times. It is not guaranteed that the order in which the records are returned are going to be consistent if the number of items in each group is not unique. In order to address this, you have to change the ROW_NUMBER function to order on the fields that make up the group in the count.
In this case, it would be A and B, resulting in:
select
t.*
from
(
select
ROW_NUMBER() over (order by t.cnt desc, t.A, t.B) as RowId, t.*
from
(
SELECT
h.A, hrl.B, dbo.f_GetCount(hrl.A,h.B) as cnt
FROM
dbo.hrl
INNER JOIN dbo.h on h.C = hrl.C
WHERE
(#A IS NULL OR h.A like '%' + #A + '%') AND
(#B IS NULL OR hrl.B = #B)
GROUP BY
hrl.B, h.A
) as t
) as t
where
t.RowId between 1 and 10
order by
t.RowId
This ends up ordering the results consistently between calls when the count of the items between groups is not unique (assuming the same set of data).
SELECT h.A, hrl.B,
dbo.f_GetCount(hrl.A,h.B) as cnt,
ROW_NUMBER() over (order by cnt desc) as row_num
FROM dbo.hrl
INNER JOIN dbo.h on h.C = hrl.C
WHERE (#A IS NULL OR h.A like '%' + #A + '%')
AND (#B IS NULL OR hrl.B = #B)
GROUP BY hrl.B, h.A
ORDER BY cnt desc
This should do the trick. I don't have SSMS in front of me to test, but you MAY have to substitute the usage of 'cnt' in the ROW_NUMBER's order by clause with a second call to the function, but this should give you the general idea.
