Newbie - help with a SQL query for a bar chart - Originally posted in APEX

Question

I originally posted this in the APEX forum but someone there suggested this is more of a SQL question.  Anyone out there who can provide some assistance?
Hi,
I'm a new user on APEX with no real SQL knowledge and I'm trying to build a dashboard with charts into an existing APEX application. Based on another application, I have come up with the following SQL code:
select null link
, CATEGORY label
, count (decode(PROJECT_STATUS,'1',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'2',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'3',PROJECT_ID))"On Hold"
, count (decode(PROJECT_STATUS,'4',PROJECT_ID))"Pipeline"
, count (decode(PROJECT_STATUS,'5',PROJECT_ID))"Pending Review"
from GRAPO_PROHEADTRK
where (PROJECT_STATUS='1' or PROJECT_STATUS='2' or PROJECT_STATUS='3' or PROJECT_STATUS='4' or PROJECT_STATUS='5' or PROJECT_STATUS='6')
group by CATEGORY
Order by COUNT(PROJECT_ID) DESC
The code from the other app was:
select null link
, FUNCTIONAL_AREA label
, count (decode(PROJECT_STATUS,'Active',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'Complete',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'On Hold',PROJECT_ID)) "On Hold"
, count (decode(PROJECT_STATUS,'Recurring',PROJECT_ID))"Recurring"
, count (decode(PROJECT_STATUS,'Pipeline',PROJECT_ID))"Pipeline"
, count (decode(PROJECT_STATUS,'Not Approved',PROJECT_ID))"Not Approved"
from PM_V2
where LOB='S2S' and (FUNCTIONAL_AREA='Accounts Payable' or FUNCTIONAL_AREA='Expense' or FUNCTIONAL_AREA='Procurement' or FUNCTIONAL_AREA='Fixed Assets')
group by FUNCTIONAL_AREA
Order by COUNT(PROJECT_ID) DESC
I'm getting a "Failed to parse SQL query!" error when I try to run validation.
Is this enough info for some assistance? Any help would really be appreciated.
Thanks,
Rachel

group by CATEGORY
Order by COUNT(PROJECT_ID) DESCIs there a problem with the code above?
It's curious that the WHERE clause includes "PROJECT_STATUS='6'", but there is no pivoted column for project_status='6', like there is for '1' through '5'. That's not necessarily a mistake, and it wouldn't raise an error in any case.
Instead of
where (PROJECT_STATUS='1' or PROJECT_STATUS='2' or PROJECT_STATUS='3' or PROJECT_STATUS='4' or PROJECT_STATUS='5' or PROJECT_STATUS='6')you could say
where PROJECT_STATUS  IN ('1', '2', '3', '4', '5', '6')but that probably has nothing to do with your current problem.
The code from the other app was:
select null link
, FUNCTIONAL_AREA label
, count (decode(PROJECT_STATUS,'Active',PROJECT_ID))"Active"
, count (decode(PROJECT_STATUS,'Complete',PROJECT_ID))"Complete"
, count (decode(PROJECT_STATUS,'On Hold',PROJECT_ID)) "On Hold"
, count (decode(PROJECT_STATUS,'Recurring',PROJECT_ID))"Recurring"
, count (decode(PROJECT_STATUS,'Pipeline',PROJECT_ID))"Pipeline"
, count (decode(PROJECT_STATUS,'Not Approved',PROJECT_ID))"Not Approved"
from PM_V2
where LOB='S2S' and (FUNCTIONAL_AREA='Accounts Payable' or FUNCTIONAL_AREA='Expense' or FUNCTIONAL_AREA='Procurement' or FUNCTIONAL_AREA='Fixed Assets')
group by FUNCTIONAL_AREA
Order by COUNT(PROJECT_ID) DESC
I'm getting a "Failed to parse SQL query!" error when I try to run validation.Is that an Apex error message? Sorry, I don't know anything about Apex.
If you can't get a more specific error message from Apex, then try debugging this statement in SQL*Plus. When you get it fixed, then you can copy it back into Apex.
If this is a SQL problem, then you should be able to re-create the problem in pure SQL.
If you can't re-create the problem in pure SQL, then it's probably an Apex problem, and belongs in the Apex forum, not here.
I don't see anything obviously wrong with your code, but I can't tell if, for example, you spelled a column name wrong, or if something has the wrong data type
Is this enough info for some assistance? Any help would really be appreciated.It wiould be better if you posted a completE script that people could run to re-create the problem, and to test their ideas.
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
Always say which version of Oracle (and any other software, such as Apex) you're using.
