SQL side grouping of field before plugging into Crystal Reports - sql

My company uses numbers as a system identifier to branches. The problem is my end users do not like seeing 000201 as a branch name. Therefore I am trying to convert these numbers to a string and then roll up the satellite locations into the main branch. The branch format is as follows:
BBBBSS so, as an example, the Nashville main branch will follow 000201 and all satellites would follow sequentially 000202, 000203, 000204.
I want all of our details to roll up into "Nashville". So any instance that ORGID is like 0002** it would roll up everything into a field named "Nashville".
Sorry if I'm not too clear. I've been banging my head against the wall so my thoughts are jumbled.

If I understand your question, there are at least Two ways i can think of accomplishing this ;
The 1st way is straight forward, you'd add a case statement for each Branch, if you have many branches i'd go with the 2nd way.
Select case SUBSTRING(cast(Branch.Id as varchar(10)), 1, 4 )
when '0002' then 'Nashville'
when '0003' then 'Branch 03'
when '0004' then 'Branch 04'
else SUBSTRING(cast(Branch.Id as varchar(10)), 1, 4 ) end OrgName,
COUNT(*)
from Branch group by SUBSTRING(cast(Branch.Id as varchar(10)), 1, 4 )
This 2nd way you would have a separate table to Hold Branch Name, etc. For demonstration i will call this table OrgTable with a OrgId containing your "0002" Ids, and a OrgName containing the "Nashville".
Select OrgTable.OrgName, count(*)
from Branch
inner join OrgTable on ( OrgTable.OrgId = SUBSTRING(cast(Branch.Id as varchar(10)), 1, 4 ))
Group By OrgTable.OrgName
I haven't checked that the SQL above is without syntax errors, but hopefully you get the picture.
HTH,

You can create a simple formula in CR to convert your ORGID to the branch name:
//Convert ORGID to string and save branch code
local stringvar branch := left(totext({Table.ORGID},0,''),4);
//Display city based on branch code
select branch
case "0002" : "Nashville"
case "0003" : "Other City"
<...>
default : "No matching branch!"

T-SQL: Single Table contains Permissions Tree

I have a SQL Server Table that contains a 'Hierarchy/Tree' of User Permissions.
Each Individual Permission can have values: 1 [Allowed], Blank [Not Allowed] & 0 [specifically Cancelled].
Each Individual Permission can be in one or more 'Permission Groups' & a User can be assigned all the Individual Permissions in one or more Permission Groups.
Each of the 'Permission Groups', in turn, can be in one or more higher level permission groups ... and eventually, all Permissions Groups are under a Master Group named 'Main Menu'.
This SQL Code:
Select
'Main Menu' Base,
Description Level1,
ParentId,
SecurityNodesId,
ListOrder,
Category,
LastModified
From SecurityNodes
Where ParentId = 1
Order By Description
Produces the following Output:
'Main Menu' has a ParentId of NULL [Not Shown in screenshot].
The 'Level1' 'Folders' contain other folders or Individual Permissions which are 'Referenced' by the Values under SecurityNodesId.
For instance, a search for SecurityNodesId 102 [Level1 - Administration] in the ParentId column returns this list of Sub Folders under 'Level2':
So ... I can access each of these sub folders by writing separate queries.
But what I want is to have an end result that displays every Node of this Permissions Tree in Table form like this:
Main Menu Level1 Level2 Level3 Level4 PermissionName PermissionValue
I have never had to do something this complex before, though I have done plenty of self-joins.
I am currently thinking that I would need to do a self join to each self join ... to get to successive Levels of the Tree ... but I believe there may be a 'recursive' approach to this that might be more efficient?
I would appreciate any help I can get with this.
Thanks in advance!
The way to solve this is with a Recursive CTE.
These are definitely more advanced than your usual SQL, but once you have your head wrapped around them, they are pretty easy to put together and VERY useful for hierarchical data (any table that stores a parent/child relationship).
A recursive CTE has two parts, separated by a UNION ALL.
The recursive seed which is ran only once and determines the starting result set for the recursion. For you, this is likely any record with a parentId of 1.
The recursive term (or member) which joins the cte (itself) to the table that holds the parent/child relationship. It will run over and over and over and over again until the Join or a WHERE filter causes it to return no new records.
In your case, it will look something like below. Note that I don't know what your starting table looks like. Namely the Level1 column from your original SQL isn't clear if that is the column name or an alias you call Level1. Furthermore it's not at all clear how you derive a "Permission Group" or "Permission Value" from this data. But... at any rate this should get you in the ballpark:
WITH reccte as (
/*
* To start the recursion we need a "Seed"... or a set of data
* that defines the starting point on which we iterate after
* the UNION ALL below.
*
* The seed here is all records with a parentid of 1
*/
SELECT Base,
ParentID,
SecurityNodesID,
Level as Level1,
NULL as Level2,
NULL as Level3,
NULL as Level4,
'?' as PermissionName,
Category as PermissionValue,
1 as depth, --track how deep we recurse
Base + '>' + Level as path --keep track of where we've been and what has led us to this point in recurssion
FROM SecurityNodes
UNION ALL
/*
* This section is the part that iterates. It continues to join
* all rows that have been collected up that point with the Security
* Nodes table until that join fails.
*/
SELECT
reccte.Base,
SecurityNodes.ParentID,
SecurityNodes.SecurityNodesID,
reccte.Level1,
/*
* Depending on how deep we are in the security hierarchy
* capture the level string to the appropriate column
*/
CASE WHEN depth = 1 THEN SecurityNodes.Level ELSE reccte.Level2,
CASE WHEN depth = 2 THEN SecurityNodes.Level ELSE reccte.Level3,
CASE WHEN depth = 3 THEN SecurityNodes.Level ELSE reccte.Level4,
'?' as PermissionName,
SecurityNodes.Category as PermissionValue,
reccte.depth + 1, --increment depth
reccte.path + '>' + SecurityNodes.Level --add to the path so we know how we got here
FROM reccte
INNER JOIN SecurityNodes
/*Join parent to child*/
ON reccte.SecurityNodesId = SecurityNodes.parentId
WHERE depth < 5 --Stop looking up if we go deeper than 4 levels.
)
SELECT *
FROM reccte
While we track depth here and stop the recursion if we hit a depth of 4, you could stop the recursion with the MAXRECURSIVE option/hint. That would just go at the end of your query:
SELECT *
FROM reccte
OPTION (MAXRECURSION 4);
It's important to add either/or to your recursive CTE otherwise you risk causing an infinite loop should a security node have a child that is also one of its ancestors which would cause it to cycle endlessly.
OPTION (MAXRECURSION 2);
I followed through on an idea I mentioned in my original post and it looks like I have achieved what I was wanting.
I don't think it is the best possible solution because I know how many total levels there currently are. If we suddenly add another level or two, the SQL will not capture everything and I'll manually have to add one or more Left Joins.
Select
'Main Menu' Base,
sn.Description Level1,
sn2.Description Level2,
sn3.Description Level3,
sn4.Description Level4,
sn.ParentId,
sn.SecurityNodesId,
sn.ListOrder,
sn.Category,
sn.LastModified
From
SecurityNodes sn
Left Join SecurityNodes sn2 On sn2.ParentId = sn.SecurityNodesId
Left Join SecurityNodes sn3 On sn3.ParentId = sn2.SecurityNodesId
Left Join SecurityNodes sn4 On sn3.ParentId = sn3.SecurityNodesId
Order By sn.ParentId, sn.Description
I would still appreciate any suggestions for a more elegant/dynamic way of achieving what I need ... but for now, the above SQL is doing the job.

SQL query , group by only one column

i want to group this query by project only because there are two records of same project but i only want one.
But when i add group by clause it asks me to add other columns as well by which grouping does not work.
*
DECLARE #Year varchar(75) = '2018'
DECLARE #von DateTime = '1.09.2018'
DECLARE #bis DateTime = '30.09.2018'
select new_projekt ,new_geschftsartname, new_mitarbeitername, new_stundensatz
from Filterednew_projektkondition ps
left join Filterednew_fakturierungsplan fp on ps.new_projekt = fp.new_hauptprojekt1
where ps.statecodename = 'Aktiv'
and fp.new_startdatum >= #von +'00:00:00'
and fp.new_enddatum <= #bis +'23:59:59'
--and new_projekt= Filterednew_projekt.new_
--group by new_projekt
*
look at the column new_projekt . row 2 and 3 has same project, but i want it to appear only once. Due to different other columns this is not possible.
if its of interested , there is another coluim projectcondition id which is unique for both
You can't ask a database to decide arbitrarily for you, which records should be thrown away when doing a group. You have to be precise and specific
Example, here is some data about a person:
Name, AddressZipCode
John Doe, 90210
John Doe, 12345
SELECT name, addresszipcode FROM person INNER JOIN address on address.personid = person.id
There are two addresses stored for this one guy, the person data is repeated in the output!
"I don't want that. I only want to see one line for this guy, together with his address"
Which address?
That's what you have to tell the database
"Well, obviously his current address"
And how do you denote that an address is current?
"It's the one with the null enddate"
SELECT name, addresszipcode FROM person INNER JOIN address on address.personid = person.id WHERE address.enddate = null
If you still get two addresses out, there are two address records that are null - you have data that is in violation of your business data modelling principles ("a person's address history shall have at most one adddress that is current, denoted by a null end date") - fix the data
"Why can't i just group by name?"
You can, but if you do, you still have to tell the database how to accumulate the non-name data that it shows you. You want an address data out of it, it has 2 it wants to show you, you have to tell it which to discard. You could do this:
SELECT name, MAX(addresszipcode) FROM person INNER JOIN address on address.personid = person.id GROUP BY name
"But I don't want the max zipcode? That doesn't make sense"
OK, use the MIN, the SUM, the AVG, anything that makes sense. If none of these make sense, then use something that does, like the address line that has the highest end date, or the lowest end date that is a future end date. If you only want one address on show you must decide how to boil that data down to just one record - you have to write the rule for the database to follow and no question about it you have to create a rule so make it a rule that describes what you actually want
Ok, so you created a rule - you want only the rows with the minimum new_stundenstatz
DECLARE #Year varchar(75) = '2018'
DECLARE #von DateTime = '1.09.2018'
DECLARE #bis DateTime = '30.09.2018'
select new_projekt ,new_geschftsartname, new_mitarbeitername, new_stundensatz
from
(SELECT *, ROW_NUMBER() OVER(PARTITON BY new_projekt ORDER BY new_stundensatz) rown FROM Filterednew_projektkondition) ps
left join
Filterednew_fakturierungsplan fp on ps.new_projekt = fp.new_hauptprojekt1
where ps.statecodename = 'Aktiv'
and fp.new_startdatum >= #von +'00:00:00'
and fp.new_enddatum <= #bis +'23:59:59'
and ps.rown = 1
Here I've used an analytic operation to number the rows in your PS table. They're numbered in order of ascending new_stundensatz, starting with 1. The numbering restarts when the new_projekt changes, so each new_projekt will have a number 1 row.. and then we make that a condition of the where
(Helpful side note for applying this technique in future.. Ff it were the FP table we were adding a row number to, we would need to put AND fp.rown= 1 in the ON clause, not the WHERE clause, because putting it in the where would make the LEFT join behave like an INNER, hiding rows that don't have any FP matching record)

Completely Unique Rows and Columns in SQL

I want to randomly pick 4 rows which are distinct and do not have any entry that matches with any of the 4 chosen columns.
Here is what I coded:
SELECT DISTINCT en,dialect,fr FROM words ORDER BY RANDOM() LIMIT 4
Here is some data:
**en** **dialect** **fr**
number SFA numero
number TRI numero
hotel CAI hotel
hotel SFA hotel
I want:
**en** **dialect** **fr**
number SFA numero
hotel CAI hotel
Some retrieved rows would have something similar with each other, like having the same en or the same fr, I would like to retrieved rows that do not share anything similar with each other, how do I do that?
I think I’d do this in the front end code rather the dB, here’s a pseudo code (don’t know what your node looks like):
var seenEn = “en not in (''“;
var seenFr = “fr not in (''“;
var rows =[];
while(rows.length < 4)
{
var newrow = sqlquery(“SELECT *
FROM table WHERE “ + seenEn + “) and ”
+ seenFr + “) ORDER BY random() LIMIT 1”);
if(!newrow)
break;
rows.push(newrow);
seenEn += “,‘“+ newrow.en + “‘“;
seenFr += “,‘“+ newrow.fr + “‘“;
}
The loop runs as many times as needed to retrieve 4 rows (or maybe make it a for loop that runs 4 times) unless the query returns null. Each time the query returns the values are added to a list of values we don’t want the query to return again. That list had to start out with some values (null) that are never in the data, to prevent a syntax error when concatenation a comma-value string onto the seenXX variable. Those syntax errors can be avoided in other ways like having a Boolean of “if it’s the first value don’t put the comma” but I chose to put dummy ineffective values into the sql to make the JS simpler. Same goes for the
As noted, it looks like JS to ease your understanding but this should be treated as pseudo code outlining a general algorithm - it’s never been compiled/run/tested and may have syntax errors or not at all work as JS if pasted into your file; take the idea and work it into your solution
Please note this was posted from an iphone and it may have done something stupid with all the apostrophes and quotes (turned them into the curly kind preferred by writers rather than the straight kind used by programmers)
You can use Rank or find first row for each group to achieve your result,
Check below , I hope this code will help you
SELECT 'number' AS Col1, 'SFA' AS Col2, 'numero' AS Col3 INTO #tbl
UNION ALL
SELECT 'number','TRI','numero'
UNION ALL
SELECT 'hotel','CAI' ,'hotel'
UNION ALL
SELECT 'hotel','SFA','hotel'
UNION ALL
SELECT 'Location','LocationA' ,'Location data'
UNION ALL
SELECT 'Location','LocationB','Location data'
;
WITH summary AS (
SELECT Col1,Col2,Col3,
ROW_NUMBER() OVER(PARTITION BY p.Col1 ORDER BY p.Col2 DESC) AS rk
FROM #tbl p)
SELECT s.Col1,s.Col2,s.Col3
FROM summary s
WHERE s.rk = 1
DROP TABLE #tbl

SELECT COALESCE(SUM(OdQty#),0)
You need to use GROUP BY to SUM.
SELECT COALESCE(SUM(Goals),0) AS TeamGoals
FROM Players
GROUP BY TeamId
After formatting your code so that we can see better where the various parts of the statement begins and ends, we can see what matches up with what.
Everything up to "till here it's fine" is one SQL SELECT statement. You need a semicolon to begin your next query, which starts with SELECT COALESCE(), but is incomplete since there is no FROM clause. Once you've put the terminator on the first statement it should run.
The second query is another question. You didn't show us the rest of the code. As TeKapa says, you need a GROUP BY clause anytime you use an aggregate function. But this is only required, if you are also including a non-aggregate column in the results.
SELECT TeamID, COALESCE(SUM(Goals),0) AS TeamGoals
FROM Players
GROUP BY TeamId
That will give you each TeamID in Players, and the total Goals for each team. You would probably also include ORDER BY TeamID
But if you simply want the combined total of all Players, it is completely valid to say
SELECT SUM(Goals) AS TotalGoals
FROM Players
Taking a step back, it seems like your query has gotten so complex, that even you may be having difficulty managing it. Hopefully others wont be asked to maintain something like this.
If such code is going into production, I recommend finding ways to modularize portions of the complexity, such as with views, or common table expressions. It may also be a good idea to store those lists of values in a table, rather than hardcoding them.

Combine Columns with similar measures in Crosstab in Cognos/SQL

So I have a crosstab that measures the amount of hours spent at a single facility. Our rows seperate the type of task for the hours worked, and the columns seperate the facility where the hours were worked.
The problem I have is that in our database we have 2 levels of facilities. Each Level 1 Facility has ten Level 2 "child" systems below it. What we want is to be able to roll all of the Level 2 facility columns' data into their respective Level 1 facility parent.
I've included an example below. The first t̶a̶b̶l̶e̶ crosstab is the one I have, and I want to get to the second t̶a̶b̶l̶e̶ crosstab.
So in our system the "parent" and "child" facilities are connected through a field called OBJ_PARENT. Each of the "children" have the name of its "parent" inside OBJ_PARENT.
I will give the SQL I have written up upon request.
EDIT: I've provided my current SQL below
select EVT_WORKORDER, EVT_DEPARTMENT, EVT_WOSTATUS, EVT_WOTYPE, EVT_FACILITY, OBJ_FACILITY, OBJ_PMD, OBJ_PARENT, BOO_HOURS, BOO_DATE, BOO_ENTERED, BOO_ACTIVITY, BOO_PERSON, ACT_ACTIVITY, ACT_TASK, ACT_WORKORDER, PRV_CODE, PRV_PROPERTY, PRV_VALUE,
sum(case when boo_person <> 'UNPAID' then boo_hours else 0 end ) "Paid Hours",
sum( boo_hours ) "All Hours"
FROM R5EVENTS
JOIN R5OBJECTS ON EVT_FACILITY = OBJ_FACILITY
JOIN R5BOOKEDHOURS ON BOO_EVENT = EVT_WORKORDER
join R5ACTIVITIES on EVT_WORKORDER = ACT_WORKORDER
JOIN r5propertyvalues ON ( ACT_TASK || '#0' = PRV_CODE)
where prv_property = 'CORESRV'
and ACT_ACTIVITY= BOO_ACTIVITY
AND EVT_DEPARTMENT = 'PK-MAINT'
AND EVT_WOTYPE IN ('JOB', 'PPM')
AND EVT_WOSTATUS IN ('R', 'FC', 'C', 'H', 'FI', 'CI', 'AP', 'IP', 'DF')
and OBJ_PMD in (#PROMPTMANY ('PMD')#)
and (OBJ_FACILITY in (#PROMPTMANY ('Park')#)
OR
OBJ_PARENT in ( SELECT OBJ_FACILITY from R5OBJECTS where OBJ_FACILITY in (#PROMPTMANY ('Park')#)))
group by EVT_WORKORDER, EVT_DEPARTMENT, EVT_WOSTATUS, EVT_WOTYPE, EVT_FACILITY, OBJ_FACILITY, OBJ_PMD, OBJ_PARENT, BOO_HOURS, BOO_DATE, BOO_ENTERED, BOO_ACTIVITY, BOO_PERSON, ACT_ACTIVITY, ACT_TASK, ACT_WORKORDER, PRV_CODE, PRV_PROPERTY, PRV_VALUE
BOO stands for "Booked"
The proper way would be:
Create a true hierarchy table in the database
Have all of the children (which, in this case with the way your data is stored, also includes what you refer to as Level 1) relate to a parent
Model in FM so that the fact table joins to the dimension table on the child
Expose the parent object from the hierarchy table
Bring the parent object into the top edge of the crosstab
If you want to do it quick and dirty, use some sort of string function to chop off the "child" part of the facility.
