I making a report in EM and I need to figure out somthing here
I have this query that I made:
SELECT
*
FROM
(
SELECT DISTINCT
patch.host as "PHost",
patch.home_location as "PDirectory",
patch.home_name as "PHome",
MAX(patch.INSTALLATION_TIME) as "Patched (Date)",
MAX(patch.PATCH_RELEASE) as "PVersion",
listagg(patch,',') WITHIN GROUP (ORDER BY patch) "Patches"
FROM
mgmt$applied_patches patch
GROUP BY patch.host, patch.home_location,patch.home_name
ORDER BY patch.host, patch.home_location
) "PCH",
(
SELECT DISTINCT
T1.PROPERTY_VALUE as "MHost",
T2.PROPERTY_VALUE as "MDirectory",
T3.PROPERTY_VALUE as "MVersion",
count(T4.PROPERTY_VALUE) as "Count of SID",
listagg(T4.PROPERTY_VALUE,',') WITHIN GROUP (ORDER BY T4.PROPERTY_VALUE) as "SID"
FROM
MGMT$TARGET_PROPERTIES T1,
MGMT$TARGET_PROPERTIES T2,
MGMT$TARGET_PROPERTIES T3,
MGMT$TARGET_PROPERTIES T4
WHERE
T1.TARGET_GUID = T2.TARGET_GUID
and T1.TARGET_GUID = T3.TARGET_GUID
and T1.TARGET_GUID = T4.TARGET_GUID
and T1.PROPERTY_NAME = 'MachineName'
and T2.PROPERTY_NAME = 'OracleHome'
and T3.PROPERTY_NAME = 'Version'
and T4.PROPERTY_NAME = 'SID'
GROUP BY T1.PROPERTY_VALUE, T2.PROPERTY_VALUE, T3.PROPERTY_VALUE
) "MGM"
WHERE
PDirectory = MDirectory
I'm getting error ORA-00904: "MDIRECTORY":....
I tried many combinations! (PCH.PDirectory = MGM.MDirectory, ......) nothing works
cheers
Mixed case names in Oracle are an abomination, and you've just been bitten by them.
Use:
"PDirectory" = "MDirectory"
.. or better still do not use special names that need quoting.
Well...
This doesn't work:
SELECT * FROM
(SELECT DUMMY AS "PDirectory" FROM DUAL) "PCH",
(SELECT DUMMY AS "MDirectory" FROM DUAL) "MGR"
WHERE PDIRECTORY = MDIRECTORY
But this works:
SELECT * FROM
(SELECT DUMMY AS "PDirectory" FROM DUAL) "PCH",
(SELECT DUMMY AS "MDirectory" FROM DUAL) "MGR"
where "PCH"."PDirectory" = "MGR"."MDirectory"
change your query accordingly.

I have a perfect code that compares the data from one table with another (see below) which works totally fine and runs fine as well in BigQuery:
with source1 as (
select
b.id,
b.qty,
a.price
from <table> as a
,unnest <details> as b
where b.status != 'canceled'
),
source2 as (
select id_, qty_, price_ from <table2>
where city != 'delhi'
)
select *
from source1 s1
full outer join source2 s2
on id = id_
where format('%t', s1) != format('%t', s2)
However, the code above runs into an error in sqlfluff i.e a certain SQL formatting rules checker that I can't bypass or turn off, see the error from sqlfluff below:
ERROR FROM SQLFLUFF:
*'s1' found in select with more than one referenced table/view' and 's2' found in select with more than one referenced table/view
Does anybody know how I can fix it ?
Windows function may perform better.
Instead of joining, the tables are unioned. Then a window function will search for combinations. As you tagged this question [Big-Query] it is tested for BigQuery:
with s1 as (
select id, qty, city from <table> where x != 'pending'
),
s2 as (
select id_, qty_, city_ from <table2>
),
concat_ as (
select 1 as dummy, * , format('%t',s1) as dummy_all
from s1
union all select 2 as dummy, * , format('%t',s2) as dummy_all
from s2
)
,combine as (
select *,
sum(if(dummy=1,1,0)) over win1 = sum(if(dummy=2,1,0)) over win1 as dummy_flag
from concat_
window win1 as (partition by id,dummy_all)
)
Select * from combine
where dummy_flag is false
I fixed the code by adding extra CTE and adjusting the where caluse this would not flag the sqlfluff rules:
To fix that, I tried the second code (see below):
added additional ctes
adjusted the where clause so that I can get all the rows where the id exists in one source but not in another and vice versa
the code seems to work but it would be great if someone could suggest how I can reduce the CTEs, considering the sqlfluff will not fail:
with s1 as (
select
b.id,
b.qty,
a.price
from <table> as a
,unnest <details> as b
where b.status != 'canceled'
),
s2 as (
select id_, qty_, price_ from <table2>
where city != 'delhi'
),
,concat_s1 as (
select
*
, format('%t',s1) as l1
from s1
)
,concat_s2 as (
select
*
, format('%t',s2) as l2
from s2
)
, combined as (
select
source1.*
,source2.*
from concat_s1 as source1
full outer join concat_s2 as source2
on source1.id_ = source2.id_
where source1.l1 != source2.l2
or source1.id is null or source2.id_ is null
I'm trying to pull 6 records using the code below but there are some cases where the information is updated and therefore it is pulling duplicate records.
My code:
SELECT column2, count(*) as 'Count'
FROM ServiceTable p
join HIERARCHY h
on p.LOCATION_CODE = h.LOCATION
where Report_date between '2017-04-01' and '2017-04-30'
and Column1 = 'Issue '
and LOCATION = '8789'
and
( record_code = 'INCIDENT' or
(
SUBMIT_METHOD = 'Web' and
not exists
(
select *
from ServiceTable p2
where p2.record_code = 'INCIDENT'
and p2.incident_id = p.incident_id
)
)
)
The problem is that instead of the six records it is pulling eight. I would just use distinct * but the file_date is different on the duplicate entries:
FILE_DATE Incident_ID Column1 Column2
4/4/17 123 Issue Service - Red
4/4/17 123 Issue Service - Blue
4/5/17 123 Issue Service - Red
4/5/17 123 Issue Service - Blue
The desired output is:
COLUMN2 COUNT
Service - Red 1
Service - Blue 1
Any help would be greatly appreciated! If you need any other info just let me know.
If you turn your original select statement without the aggregation function into a subquery, you can distinct that on your values that are not the changing date, then select a COUNT from there. Don't forget your GROUP BY clause at the end.
SELECT Column2, COUNT(Incident_ID) AS Service_Count
FROM (SELECT DISTINCT Incident_ID, Column1, Column2
FROM ServiceTable p
JOIN HIERARCHY h ON p.LOCATION_CODE = h.LOCATION
WHERE Report_date BETWEEN '2017-04-01' AND '2017-04-30'
AND Column1 = 'Issue '
AND LOCATION = '8789'
AND
( record_code = 'INCIDENT' or
(
SUBMIT_METHOD = 'Web' and
NOT EXISTS
(
SELECT *
FROM ServiceTable p2
WHERE p2.record_code = 'INCIDENT'
AND p2.incident_id = p.incident_id)
)
)
)
GROUP BY Column2
Also, if you are joining tables it is a good practice to fully qualify the field you are selecting. Example: p.Column2, p.Incident_ID, h.LOCATION. That way, even your distinct fields are easier to follow where they came from and how they relate.
Finally, don't forget that COUNT is a reserved word. I modified your alias accordingly.
If you are using an aggregation function (count), you should use group by for the column not in the aggregation function:
SELECT column2, count(*) as 'Count'
FROM ServiceTable p
join HIERARCHY h
on p.LOCATION_CODE = h.LOCATION
where Report_date between '2017-04-01' and '2017-04-30'
and Column1 = 'Issue '
and LOCATION = '8789'
and
( record_code = 'INCIDENT' or
(
SUBMIT_METHOD = 'Web' and
not exists
(
select *
from ServiceTable p2
where p2.record_code = 'INCIDENT'
and p2.incident_id = p.incident_id
)
)
)
group by column2
I'm creating a view in MariaDB and i'm having trouble making it work for a couple of fields. Currently this is working:
( SELECT DISTINCT IFNULL(grades.`grade`,'No Grade')
FROM `table` grades
WHERE userinfo.`id` = grades.`id`
AND grades.`Item Name` = 'SOMEINFO'
) 'SOMENAME',
But i need to add a select where the 'No grade' is, in the following form
( SELECT DISTINCT IFNULL( grades.`grade`,
SELECT IF( EXISTS
( SELECT *
FROM `another_table`
WHERE userid = 365
AND courseid = 2
), 'Enrolled', 'Not enrolled'
)
)
FROM `table` grades
WHERE userinfo.`id` = grades.`id`
AND grades.`Item Name` = 'SOMEINFO'
) 'SOMENAME',
i know that
SELECT IF( EXISTS( SELECT *
FROM `another_table`
WHERE userid = 365
AND courseid = 2
),
'Enrolled', 'Not enrolled'
)
is working too, but now the whole thing it's giving me an error, so any suggestions would be greatly appreciated
Thanks
This looks like a subquery:
(SELECT DISTINCT IFNULL(grades.`grade`,
SELECT IF( EXISTS (SELECT *
FROM `another_table`
WHERE userid = 365 AND courseid = 2
), 'Enrolled', 'Not enrolled'
)
)
FROM `table` grades
WHERE userinfo.`id` = grades.`id` AND
grades.`Item Name` = 'SOMEINFO'
) as SOMENAME,
You are using a subquery that returns two columns in a position where a scalar subquery is expected. A scalar subquery returns one column in at most one row.
Unfortunately, there is no easy way to do what you want in MySQL, because of the restrictions on views. I would advise you to rewrite the logic so the exists is handled using a left join in the from clause.
I am working with a tool that would extract some data from an Access Database. So basically, i am working on a query to get this data.
Below is the code i am currently working on.
I am getting an error: Syntax error in FROM clause
I can't seem to find where the query is going wrong. I would appreciate any help! Thank youu.
EDIT: putting my actual query

I have a complicated select statement that when it is executed, I give it a date or date range I want and the output comes out. The problem is I don't know how to join the same SQL statement with the first Statement having 1 date range and the second statement having another data range. Example below:
When I execute the select statement, I choose for the Month of November:
EMPLID NAME Current_Gross_Hours(November)
When I execute the select statement again, I choose from January to November:
EMPLID NAME Year_To_Date_Hours(January - November)
What I want:
EMPLID NAME Current_Gross_Hours(November) Year_To_Date_Hours(January - November)
The SQL Select statement runs correctly if execute by themselves. But I don't know how to join them.
Here is the SQL code that I want to write, but I don't know how to write the SQL statement correctly. Any help or direction is greatly appreciated.

You are missing a SELECT ... FROM at the start. The AS keyword only works when creating column aliases, not query block aliases. Quotation marks are only necessary for case-sensitive column names - they don't look incorrect in your example but they frequently cause mistakes.
SELECT Q1.NAME, ...
FROM
(
SELECT ...
) Q1
JOIN
(
SELECT ...
) Q2
ON Q1.EMPLID=Q2.EMPLID
ORDER BY Q1.NAME
