Is it possible to have a subquery in a WHERE statement with additional qualifiers? For instance, I have two tables on two different machines. I am trying to compare the tables and see which items only exist on one machine, but only a certain type of item. I only sync two types of items. I can run this query and it works:
select
ItemCode as style,
ISNULL(U_certno,'') as U_certno,
U_he, ISNULL(U_mold,'N') as U_mold
from ITEMS Z
where
z.itemcode <> (SELECT distinct Q.style
FROM remote.system.table Q where Q.style = Z.ItemCode)
That much works, I think. If I change the z.itemcode <> to z.itemcode =, I toggle between 0 results (sync is current), and all records. However, when I add:
and (z.U_he like 'y' or z.U_mold like 'y')
it gives me all items in the ITEMS table that have those two criteria, regardless of the subquery. I have tried all manners of parenthesis, to no avail. What am I doing wrong? I didn't bother trying a join, since I want dissimilar items, not matches. Any help would be appreciated. This is MSSQL 2008 R2.
select
ItemCode as style,
ISNULL(U_certno,'') as U_certno,
U_he, ISNULL(U_mold,'N') as U_mold
from ITEMS Z
where not exists (
select 1
from remote.system.table Q
where Q.style = Z.ItemCode
)
and 'y' IN (z.U_he, z.U_mold)

In MS-Access I'm trying to join three tables. The third table is created from a sub-query designed to aggregate dates because I don't want multiple records per day when aligned with the first table.
When I entered the left join sub-query, I got this error:
The field is too small to accept the amount of data you attempted to
add. Try inserting or pasting less data.
I've run the sub-query separately and it returns about 19,000 records. Which is quite smaller than the actual table. If I use the actual table, the query works just fine, but it includes the duplicate records when there is more than one entry per day on the third table.
SELECT
SUM([ACD Calls]),
(SUM([Avg ACD Time]*[ACD Calls])/SUM([ACD Calls]))/86400,
(SUM([Avg ACW Time]*[ACD Calls])/SUM([ACD Calls]))/86400,
((SUM([Hold Time])/SUM([ACD Calls])))/86400,
((SUM([Avg ACD Time]*[ACD Calls])
+ SUM([Avg ACW Time]*[ACD Calls]))/SUM([ACD Calls]))/86400,
SUM([Time Adhering])/SUM([Total Time Scheduled]),
SUM([SS])/SUM([SO])
FROM
(
(
[GroupSumDaily]
LEFT JOIN Adherence_WKLY ON (GroupSumDaily.[Day] = Adherence_WKLY.[Day])
AND (GroupSumDaily.Agent = Adherence_WKLY.Agent)
)
LEFT JOIN
(
SELECT Evaluation_List.[Agent],
Evaluation_List.Recording_Date,
SUM(Evaluation_List.[Score]) as SS,
SUM(Evaluation_List.[Out of]) as SO
From Evaluation_List
Group By Evaluation_List.[Recording_Date],
Evaluation_list.[Agent]
)
as Evals ON (GroupSumDaily.[Day] = Evals.[Recording_Date])
AND (GroupSumDaily.Agent = Evals.Agent)
)
WHERE
(
[GroupSumDaily].[Agent] = "LastName FirstName"
AND Month([GroupSumDaily].[Day]) =1
AND Year([GroupSumDaily].[Day]) =2018
AND [GroupSumDaily].[Day] > #2/23/2015#
)
It looks like you don't have a "main" table to query from.
I'd try removing the first two open brackets after the FROM statement (and their equivalent closing brackets.)
If that doesn't fix it, try moving the whole sub-query into a separate query and selecting from the results...
It turns out the subquery fields are automatically limited to 50 characters and this was the root of the problem. When I limited the return to LEFT([Agent], 50), the error disappeared. Is there a way to set character length is a subquery field?
The other odd things is, none of my fields were actually over 50 characters... when I ran Select [Agent] Where LEN([Agent]) >= 50, it returned only 1 records, and it was the "NEW" blank record from the bottom. I confirmed that it completely blank, with no spaces or tabs. Very confusing.
I'm in need of some assistance. I have search and not found what I'm looking for. I have an assigment for school that requires me to use SQL. I have a query that pulls some colunms from two tables:
SELECT Course.CourseNo, Course.CrHrs, Sections.Yr, Sections.Term, Sections.Location
FROM Course
INNER JOIN Sections ON Course.CourseNo = Sections.CourseNo
WHERE Sections.Term="spring";
I need to add a Totals row at the bottom to count the CourseNo and Sum the CrHrs. It has to be done through SQL query design as I need to paste the code. I know it can be done with the datasheet view but she will not accept that. Any advice?
To accomplish this, you can union your query together with an aggregation query. Its not clear from your question which columns you are trying to get "Totals" from, but here's an example of what I mean using your query and getting counts of each (kind of useless example - but you should be able to apply to what you are doing):
SELECT
[Course].[CourseNo]
, [Course].[CrHrs]
, [Sections].[Yr]
, [Sections].[Term]
, [Sections].[Location]
FROM
[Course]
INNER JOIN [Sections] ON [Course].[CourseNo] = [Sections].[CourseNo]
WHERE [Sections].[Term] = [spring]
UNION ALL
SELECT
"TOTALS"
, SUM([Course].[CrHrs])
, count([Sections].[Yr])
, Count([Sections].[Term])
, Count([Sections].[Location])
FROM
[Course]
INNER JOIN [Sections] ON [Course].[CourseNo] = [Sections].[CourseNo]
WHERE [Sections].[Term] = “spring”
You can prepare your "total" query separately, and then output both query results together with "UNION".
It might look like:
SELECT Course.CourseNo, Course.CrHrs, Sections.Yr, Sections.Term, Sections.Location
FROM Course
INNER JOIN Sections ON Course.CourseNo = Sections.CourseNo
WHERE Sections.Term="spring"
UNION
SELECT "Total", SUM(Course.CrHrs), SUM(Sections.Yr), SUM(Sections.Term), SUM(Sections.Location)
FROM Course
INNER JOIN Sections ON Course.CourseNo = Sections.CourseNo
WHERE Sections.Term="spring";
Whilst you can certainly union the aggregated totals query to the end of your original query, in my opinion this would be really bad practice and would be undesirable for any real-world application.
Consider that the resulting query could no longer be used for any meaningful analysis of the data: if displayed in a datagrid, the user would not be able to sort the data without the totals row being interspersed amongst the rest of the data; the user could no longer use the built-in Totals option to perform their own aggregate operation, and the insertion of a row only identifiable by the term totals could even conflict with other data within the set.
Instead, I would suggest displaying the totals within an entirely separate form control, using a separate query such as the following (based on your own example):
SELECT Count(Course.CourseNo) as Courses, Sum(Course.CrHrs) as Hours
FROM Course INNER JOIN Sections ON Course.CourseNo = Sections.CourseNo
WHERE Sections.Term = "spring";
However, since CrHrs are fields within your Course table and not within your Sections table, the above may yield multiples of the desired result, with the number of hours multiplied by the number of corresponding records in the Sections table.
If this is the case, the following may be more suitable:
SELECT Count(Course.CourseNo) as Courses, Sum(Course.CrHrs) as Hours
FROM
Course INNER JOIN
(SELECT DISTINCT s.CourseNo FROM Sections s WHERE s.Term = "spring") q
ON Course.CourseNo = q.CourseNo
I have a matrix in ssrs2008 like below:
GroupName Zone CompletedVolume
Cancer 1 7
Tunnel 1 10
Surgery 1 64
ComplatedVolume value is coming by a specific expression <<expr>>, which is equal to: [Max(CVolume)]
This matrix is filled by a stored procedure that I am not supposed to change if possible. What I need to do is that not to show the data whose CompletedVolume is <= 50. I tried to go to tablix properties and add a filter like [Max(Q9Volume)] >= 50, but when I try to run the report it says that aggregate functions cannot be used in dataset filters or data region filters. How can I fix this as easy as possible?
Note that adding a where clause in sql query would not solve this issue since there are many other tables use the same SP and they need the data where CompletedVolume <= 50. Any help would be appreciated.
EDIT: I am trying to have the max(Q9Volume) value on SP, but something happening I have never seen before. The query is like:
Select r.* from (select * from results1 union select * from results2) r
left outer join procedures p on r.pid = p.id
The interesting this is there are some columns I see that does not included by neither results1/results2 nor procedures tables when I run the query. For example, there is no column like Q9Volume in the tables (result1, result2 and procedures), however when I run the query I see the columns on the output! How is that possible?
You can set the Row hidden property to True when [Max(CVolume)] is less or equal than 50.
Select the row and go to Row Visibility
Select Show or Hide based on an expression option and use this expression:
=IIF(
Max(Fields!Q9Volume.Value)<=50,
True,False
)
It will show something like this:
Note maximum value for Cancer and Tunnel are 7 and 10 respectively, so
they will be hidden if you apply the above expression.
Let me know if this helps.
I am confused by the results of a query I am running. Hopefully this doesn't end with me slapping my head and feeling like an idiot, but here goes (SQL Server 2008).
First query was this:
SELECT p.product_number,p.long_desc
FROM products p
WHERE p.prod_status = 1
AND ((p.long_desc IS NULL) OR (p.long_desc LIKE '%N/A%'))
ORDER BY p.product_number
Second version is this:
SELECT p.product_number,p.long_desc
FROM products p
WHERE p.prod_status = 1
AND p.long_desc IS NULL
OR p.long_desc LIKE '%N/A%'
ORDER BY p.product_number
There are three products in the second version that do not appear in the first, yet to me these two queries should give identical results. The three items that appear in the second but not the first all have the value N/A in the long_desc column.
However there are many others with N/A as well and show up in both versions.
What don't I understand about the use of parenthesis here?
AND has a higher precedence than OR (see documentation), so without the parentheses, the query is equivalent to this:
SELECT p.product_number,p.long_desc
FROM products p
WHERE (p.prod_status = 1
AND p.long_desc IS NULL)
OR p.long_desc LIKE '%N/A%'
ORDER BY p.product_number
I have the below query. The problem is the last column productdesc is returning two records and the query fails because of distinct. Now i need to add one more column in where clause of the select query so that it returns one record. The issue is that the column i need
to add should not be a part of group by clause.
SELECT product_billing_id,
billing_ele,
SUM(round(summary_net_amt_excl_gst/100)) gross,
(SELECT DISTINCT description
FROM RES.tariff_nt
WHERE product_billing_id = aa.product_billing_id
AND billing_ele = aa.billing_ele) productdescr
FROM bil.bill_sum aa
WHERE file_id = 38613 --1=1
AND line_type = 'D'
AND (product_billing_id, billing_ele) IN (SELECT DISTINCT
product_billing_id,
billing_ele
FROM bil.bill_l2 )
AND trans_type_desc <> 'Change'
GROUP BY product_billing_id, billing_ele
I want to modify the select statement to the below way by adding a new filter to the where clause so that it returns one record .
(SELECT DISTINCT description
FROM RRES.tariff_nt
WHERE product_billing_id = aa.product_billing_id
AND billing_ele = aa.billing_ele
AND (rate_structure_start_date <= TO_DATE(aa.p_effective_date,'yyyymmdd')
AND rate_structure_end_date > TO_DATE(aa.p_effective_date,'yyyymmdd'))
) productdescr
The aa.p_effective_date should not be a part of GROUP BY clause. How can I do it? Oracle is the Database.
So there are multiple RES.tariff records for a given product_billing_id/billing_ele, differentiated by the start/end dates
You want the description for the record that encompasses the 'p_effective_date' from bil.bill_sum. The kicker is that you can't (or don't want to) include that in the group by. That suggests you've got multiple rows in bil.bill_sum with different effective dates.
The issue is what do you want to happen if you are summarising up those multiple rows with different dates. Which of those dates do you want to use as the one to get the description.
If it doesn't matter, simply use MIN(aa.p_effective_date), or MAX.
