SELECT MAX query

Hai Friends,
The following is my select query
SELECT MAX( MBLNR )
FROM ZMIGO
INTO TABLE IT_MAX.
Right now my Z table is empty. but when i debug the program it showing 1 entry and when i double the internal table there is no value and it is blank. why it is showing as 1 entry.

Hi,
Try using:-
DATA : v_mblnr TYPE zmigo-mblnr.
SELECT MAX( DISTINCT mblnr ) FROM zmigo INTO v_mblnr.
IF sy-subrc NE 0.
CLEAR v_mblnr.
ENDIF.
Hope this helps you.
Regards,
Tarun

SQL query problem - select max (case... aggregate function)

Hi,
I have a problem with below sql query, it gives me problem/error message 'ORA-00937: not a single-group group function', why?
select sag.afdeling, sag.sagsnr, to_char(sag.start_dato, 'yyyy-mm-dd'), sag.stat, BOGF_TRANS.TRANSTYPE,
max (case when BOGF_TRANS.TRANSTYPE = 'K' then sum(bogf_trans.belobdkk) end) + -- as "TRANSTYPE K",
max (case when BOGF_TRANS.TRANSTYPE = 'D' then sum(bogf_trans.belobdkk) end) as "TRANSTYPE K & D",
max (case when BOGF_TRANS.TRANSTYPE = 'S' then sum(bogf_trans.belobdkk) end) as "SUM TRANSTYPE S"
from sag
join bogf_trans on sag.selskab = bogf_trans.selskab and sag.sagsnr = bogf_trans.sagsnr and sag.afdeling = bogf_trans.afdeling
where SAG.SELSKAB=37 and SAG.AFDELING = 'SUS' AND SAG.SAGSNR = 10876
group by sag.afdeling, sag.sagsnr, sag.start_dato, sag.stat, BOGF_TRANS.TRANSTYPE
If I exclude (columns) as below it give me correct summations (max (case... sum(...)) but then I miss some important info that I need
select
max (case when BOGF_TRANS.TRANSTYPE = 'K' then sum(bogf_trans.belobdkk) end) + -- as "TRANSTYPE K",
max (case when BOGF_TRANS.TRANSTYPE = 'D' then sum(bogf_trans.belobdkk) end) as "TRANSTYPE K & D",
max (case when BOGF_TRANS.TRANSTYPE = 'S' then sum(bogf_trans.belobdkk) end) as "SUM TRANSTYPE S"
from sag
join bogf_trans on sag.selskab = bogf_trans.selskab and sag.sagsnr = bogf_trans.sagsnr and sag.afdeling = bogf_trans.afdeling
where SAG.SELSKAB=37 and SAG.AFDELING = 'SUS' AND SAG.SAGSNR = 10876
group by sag.afdeling, sag.sagsnr, sag.start_dato, sag.stat, BOGF_TRANS.TRANSTYPE
Any ideas?

Moved to more sutable forum, sorry.

How to select Max in a multi query?

Hi all,
I got this query:
select DEPTNO, EMPNO from EMP1 minus select DEPTNO, EMPNO from EMP2;
I want to get single row from the results of this query, so I may use MAX or MIN or where rownum<2.
How can I do this please....
I tried: SELECT MAX(select DEPTNO, EMPNO from EMP1 minus select DEPTNO, EMPNO from EMP2) from DUAL;
but I got syntax error :(
Please help....
Thanks

I want to get single row from the results of this querywhich row is correct row & why?
How many rows returned now? (Since we don't have your tables or data.)

I have this query so far,
SELECT
MAX (TEMP.COSTO) COSTO,
TEMP.M_PRODUCT_ID,
TEMP.ANO
FROM TEMP TEMP
INNER JOIN(
SELECT MAX(ANO) ANO, M_PRODUCT_ID
FROM TEMP I
GROUP BY M_PRODUCT_ID
) LA ON LA.ANO = TEMP.ANO AND LA.M_PRODUCT_ID = TEMP.M_PRODUCT_ID
GROUP BY
TEMP.M_PRODUCT_ID,
TEMP.ANO
but my intention is not to have the max cost, my intention is to query in this order
first i need to select distinct m_product_id then
for every m_product_id i need to
filter max (ano) then filter max (mes) then filter max (dia)
I need the result set like this.
C_INVOICE_ID DIA MES ANO SOCIO PRODUCTO_NOM M_PRODUCT_ID CATERGORIA COSTO
1015 15 2 2010 1520 ALURON 100MG X 30 TABLETAS 1530 15 2.15

15132 25 9 2010 1585 AMOXAL 250MG X 75ML SUSPENSION 1534 15 3.4
please i really apritiated any help, thanks pd:i'm using oracle 9i

Hi,
Thanks for posting the CREATE TABLE and INSERT statements. Why are there two tables, and two sets of data? Was that a mistake?
Sorry, I don't uderstand the problem.
For m_product_id=1531, for example, why do you want
INSERT INTO TEMP VALUES(5654,     5, 2, 2010,'1520','AMARYL 2MG X 15 TABLETAS',1531,15,4.2);selected, and not
INSERT INTO TEMP VALUES(116544,     8, 8, 2010,'1220','AMARYL 2MG X 15 TABLETAS',1531,15,4.8);Both rows have ano=2010, so don't you want the one with the higher mes (8 > 2)?
I think what you'll want is a Top-N Query , something like this:
WITH     got_r_num     AS
     SELECT     temp.*     -- or list columns you want
     ,     RANK () OVER ( PARTITION BY m_product_id
                      ORDER BY          ano     DESC     NULLS FIRST
                      ,          mes     DESC     NULLS FIRST
                      ,          dia     DESC     NULLS FIRST
                    )          AS r_num
     FROM     temp
--     WHERE     ...     -- any filtering goes here
SELECT     *     -- or list all columns except r_num
FROM     got_r_num
WHERE     r_num     = 1
;What if there's a tie? For example, if you add another row to the sample data:
INSERT INTO TEMP VALUES(9876,     15,2, 2010,'1520','ALURON 100MG X 30 TABLETAS',1530,15,2.15);The query above would include both c_invoice_id=9876 and 1015. If you want just one of those rows, add more expressions to the analytic ORDER BY clause and/or use ROW_NUMBER instead of RANK.

How to : SELECT MAX(EmpID) / count(*) in SELECT Query

Hi,
I like to find out the Maximum of the EmpID that is in the DB table.
So I need to perform a select Query:
Select MAX(EmpID) from EmpTable
or Select Count(*) from EmpTable
<StatementName>
<dbTableName action=SELECT>
   <table>realDbTableName</table>
     <access>
         <??? />
      </access>
</dbTableName>
</StatementName>
I cannot type MAX(EmpID) or count(*) as access element
So what should I mention in the Access?
Thanks & regards,
Siva Maranani.

if 0CALDAY is used as a characteristic then you have to convert that as a key figure using a replacement path variable.
Please see the below link for changing 0CALDAY as a key figure using Replacement path
http://www.sd-solutions.com/documents/SDS_BW_Replacement%20Path%20Variables.html
https://websmp106.sap-ag.de/~sapdownload/011000358700001963972003E/HowToCalcWithAttr.pdf
Now you have to create an exception "Top N Rows" based on the replacement path variable created above.
This will solve your problem.

How to use select max and min query..

hi gurus,
we have got a custom report for develoment.
the report has to fetch the max and min salarys department wise....
how to pick up max & min sal ansal from table pa0008.

Hi,
Try the following
select max(sal)
           min(sal)
           from <database table>
           into <internal table>
           group by department
           where <where condition>.
Here we assume that sal is the field holding the salary and department is the name of the field in the database table. Where condition is optional.
Hope this helps.

Select Max and ResultSet Problem With Access

The following code is producing a 'null pointer excepetion' error and I know why it is occurring I just do not know how to fix the problem.
Basically I want to automitically generate a unique ID that is one number higher than the max ID (data is stored within an Access database). The ID field is made up of first and last initial taken from parsing previous login info ('JS-01', 'JS-02', ect.). If there are no IDs in the database that match your login info I want to set the new ID equal to 'JS-01' if your login is 'James Smith' for example.
The problem is explained within the code below.
<%
//define resultset and statement
ResultSet rss=null;
ResultSet rs=null;
Statement stmt=null;
//HERE IS WHERE YOU PARSE THE LOGIN INFO
String finitial = (String)session.getAttribute("vfirst");//vfirst=JIM
String linitial = (String)session.getAttribute("vlast");//vlast=SMITH
char f = finitial.charAt(0);
char n = linitial.charAt(0);
String sID = f+""+n;//NOW sID CONTAINS 'JS'
try {
//Using the current database connection create a statement
stmt=con.createStatement();
//QUERY TO SELECT MAX ID
//NOTE: CURRENTLY THERE ARE NO IDs LIKE 'JS' IN THE DATABASE !!!!!!
String sql="SELECT Max(ID) As MaxID FROM tblError Where ID LIKE '%"+sID+"%'" ;
rs = stmt.executeQuery(sql);
String newID;
//HERE THE RESULT SET SHOULD BE NULL BUT IT IS NOT. I KNOW THIS BECAUSE WHEN I REPLACE String iID WITH A LITERAL LIKE 'JS-03' THE LOGIC WILL EXECUTE CORRECTLY AND GIVE ME 'JS-04'. IF I LEAVE THE CODE LIKE IT IS THEN I GET THE NULL POINTER VALUE ERROR BECAUSE YOU CANNOT RESOLVE "MaxID" WHEN THE RESULT SET IS NULL. IF THE RESULT SET IS NULL IT SHOULD NOT EVEN EXECUTE ANY OF THIS CODE WITHIN THE 'if' STATEMENT, BUT IT IS. SO BASICALLY JSP IS LEAVING ME WITH A MAJOR OXYMORON AND I WOULD APPRECIATE ANY ADVICE THAT WOULD HELP ME SOLVE THIS PROBLEM.
if(rs.next()){
String iID = rs.getString("MaxID");
String letters = iID.substring(0,3);
int numbers = Integer.parseInt(iID.substring(3,5));
numbers = numbers + 1;
if(numbers < 10){
newID = letters + "0" + numbers;}
else{
newID = letters + numbers;
else{//IF THERE IS NO RESULT SET THAN THE ID SHOULD BE 'JS-01'
newID = sID + "-01";
%>
Because this an Access database I cannot use any null exception functions such as NVL or COALESCE which are specific to Oracle and SQL Server I beleive.

The max() will return a result set, even if the max value is null.
You should check to see if iID is null.
if(rs.next())
   String iID = rs.getString("MaxID");
   if (iID == null)
       newID = sID + "-01";
   else
      String letters = iID.substring(0,3);
      ... etc ...
}

Sub-Select Count query breaking TOAD

Oracle 10.2.0.4.0
Running TOAD 9.1
I am running some SQL on our eBusiness Suite:
SELECT pha.segment1
     , pha.type_lookup_code
     , (SELECT COUNT(DISTINCT pha2.po_header_id)
          FROM po.po_headers_all pha2
             , po.po_lines_all pla
         WHERE pha2.po_header_id = pla.po_header_id
           AND pla.contract_id = pha.po_header_id) po_count
     , (SELECT MAX(pha2.creation_date)
          FROM po.po_headers_all pha2
             , po.po_lines_all pla
         WHERE pha2.po_header_id = pla.po_header_id
           AND pla.contract_id = pha.po_header_id) latest_cpa_po
FROM po.po_headers_all pha
     , po.po_vendors pv
     , po.po_vendor_sites_all pvsa
WHERE pha.vendor_id = pv.vendor_id
   AND pha.vendor_site_id = pvsa.vendor_site_id
--   AND pv.VENDOR_NAME LIKE 'H%'
   AND pha.vendor_id = 98
   AND pha.type_lookup_code = 'CONTRACT'
   AND pha.org_id IN(7041, 7042);The above query runs quicky (approx. 1 second). If I take out the AND pha.vendor_id = 98 then the query takes a few minutes to run.
When I try to export it, or scroll down to view > 500 rows, TOAD crashes.
I know this isn't a TOAD forum, but I think that this is probably an issue with my no doubt rubbish SQL.
If I take out this sub-select, then the problem doesn't happen:
     , (SELECT COUNT(DISTINCT pha2.po_header_id)
          FROM po.po_headers_all pha2
             , po.po_lines_all pla
         WHERE pha2.po_header_id = pla.po_header_id
           AND pla.contract_id = pha.po_header_id) po_countHowever, I can't work out a better way of getting the data I need.
The sub-select counts POs which have been raised where the contractID on the PO line is the same as the PO Header ID from the main query.
Any advice please, on what I could do to sort this out would be much appreciated.
Thanks!

Hi,
It looks like you can replace both scalar sub-queries with a join, like this:
WITH     header_lines_summary     AS
     SELECT    pla.contract_id
          ,       COUNT (DISTINCT pha2.po_header_id)     AS po_count
          ,       MAX (pha2.creation_date)          AS latest_cpa_po
          FROM        po.po_headers_all pha2
             ,        po.po_lines_all   pla
         WHERE        pha2.po_header_id = pla.po_header_id
      GROUP BY       pla.contract_id
)                                        -- Everything up to this line is new
SELECT pha.segment1
     , pha.type_lookup_code
     , hls.po_count                              -- Changed
     , hls.latest_cpa_po                         -- Changed
FROM po.po_headers_all     pha
     , po.po_vendors           pv
     , po.po_vendor_sites_all      pvsa
     , header_lines_summary     hls                    -- New
WHERE pha.vendor_id          = pv.vendor_id
   AND pha.vendor_site_id     = pvsa.vendor_site_id
   AND pha.po_header_id          = hls.contract_id (+)          -- New
--   AND pv.VENDOR_NAME      LIKE 'H%'
   AND pha.vendor_id           = 98
   AND pha.type_lookup_code      = 'CONTRACT'
   AND pha.org_id           IN (7041, 7042);Aside from the sub-query (which is entirely new), the query above is just what you posted, with 2 lines changed and 2 lines added, as marked.
This should be more efficient, but I don't know for certain that it will solve the Toad problem.
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables, and also post the results you want from that data.
It never hurts to say what version of Oracle you're using.

Max query

Hello all,
I have two table table1 and table2 with two columns
Table1 : Employee ID,Value
Table2 : UseID, value.
Now I want to create query which use the maximum value of any one value
SELECT t1.Employeeid,t2.UseID from table1 t1,table2 t2
Where t1.Employeeid=t2.userid where Employeeid=max(Employeeid,UseID)
Is it possible ?

This is what you wanted, right!
select max(empid)
from ( select empid
           from table1
          union all
         select userid
           from table2
       )And what i was saying is that
SELECT col1,col2,col3
FROM table1
UNION ALL
SELECT col1,col2,null
FROM table2;That is number of columns in both SELECT list should be same.

Select MAX Date

I have the following recordset that includes a Patient Identification Number along with a Date of Service:
PatientID DOS
====== ======
11111      1/1/2015
11111      1/5/2015
33333      1/3/2015
22222      1/2/2015
11111      2/1/2015
22222      1/1/2015
11111      1/2/2015
33333      2/10/2015
11111      2/11/2015
22222      1/1/2015
I need a query that shows the MAX DOS for each patient. For example:
PatientID DOS
====== ======
11111      2/11/2015
22222      1/2/2015
33333      2/10/2015
Is this possible?
Thanks.

t1 and t2 is alias for table
SELECT
PatientID ,( select max ( DOS ) from Patient as t2 where t2 . PatientID = t1.PatientID ) DOS
FROM
Patient as t1
group by PatientID
I only have one table in select and subselect

Using SELECT MAX to default to certain days

Gurus,
Right now, I use SELECT MAX("File Date"."Date")FROM "Subject Area" to pull the most recent date available. I'd like for this to pull the last two or three days of data available. Any suggestions?
I have this set under a report filter for the analysis. Thanks in advance!

Try this
SELECT File Date.Date saw_0, TOPN(File Date.Date, 3) saw_1, Facts."#Sales" saw_2 FROM "Subject Area" ORDER BY saw_0
Let me know updates

Your initial post talks about logical query from OBIEE, so I've logical query. try to put that in answers instead of running in Toad or sql developer etc..

SELECT MAX(field) / SELECT MIN(field) return wrong values

Hi,
I have the query:
Select
    MAX(b1.time_s) as time_s
From
    BUSINESS_INVOCATIONS b1
Where
    b1.time_s >= 1219217034000
    AND b1.rec_sess_id = 2197756621378027521
    AND b1.comp_id IN ( Select id From J2EE_CONFIGURATION_BEAN Where j2eeApplicationsTableId = 378302371920347137 )
This return the MAX value of the comp_id and not the MAX value of the b1.time_s
looks like there is a BUG in MAXDB when i have a join of two tables the MAX/MIN functions works on the wrong fields!
If i change the query to be:
Select
    max(b1.time_s) as time_s
From
    BUSINESS_INVOCATIONS b1,
    J2EE_CONFIGURATION_BEAN jcb
Where
    b1.time_s >= 1219217034000
    AND b1.rec_sess_id = 2197756621378027521
    AND jcb.j2eeApplicationsTableId = 378302371920347137
    AND b1.comp_id = jcb.id
The MIN/MAX functions works good and return the right value
Pleasehelp me to find what is the problem and if any one already have a solution.
Thanks,
Yosef

HELP: SELECT MAX( Exp1, Exp2)

SELECT MAX( 1,2,3) FROM DUAL:
Should return 3 but it does not. Each element 1 2 3 is an expression. According to "Oracle 9i SQL Ref" MAX uses standard sql Expressions which Includes an Expression List which is delimited by "," Since SELECT MAX(2) FROM DUAL Returns 2 it should iterate.
I have a table
ID: VAL1: VAL2
I want to query and return 2 columns
ID: MAX(VAL1,VAL2)
I know I probably forgot something stupid.
Thank you for any help.

max finds the maximum value from one column (or expression) from multiple rows.
so this will work:
select max(x) from (
select 1 x from dual
union
select 2 from dual
union
select 3 from dual
to find the maximum value from different columns from one row use "greatest".
select greatest(1,2,3) from dual;

SELECT MAX query
