Help with "distint count" in query

Hi
I have a query that returns the following error:
ORA 00936: Missing Expression
and also after running it again
I get ORA 00900: Invalid SQL statement.
The query is as follows:
SELECT
        DISTINCT student_id,
        COUNT(student_id),
        ABSENCE_REASON_CODE,
        calendar_date,
        attendance_status,
        FROM AT_HOURLY_ATTENDANCE_RECORDS
        WHERE (absence_reason_code = 'UC')
       OR (absence_reason_code = '1');all help is gratefully acknowledged. Thanks in advance

Hi
Thanks to both guys for helping me out.. (Steven and Gasparatto)
The query still has the following problem:
ORA-00900: invalid SQL statement
I wonder why this is happening..
(Toad is pointing out student_id as a possible culprit
the code again is:
SELECT
        DISTINCT student_id,
        COUNT(student_id),
        ABSENCE_REASON_CODE,
        calendar_date,
        attendance_status
        FROM AT_HOURLY_ATTENDANCE_RECORDS
        WHERE (absence_reason_code = 'UC')
       OR (absence_reason_code = '1');Please excuse me for my naive questions. I have learnt a lot today itself. Thanks a lot again

Help with Converting an Access query

Hello:
First time poster and would appreciate some help in converting this Access query into T-SQL so I can use in a Stored Procedure. I don't need help in resolving the syntax for the variables as parameter in the second query, but stuck in writing the first query
in T-SQL . I assume I need some type of nested query with a left join to another query in T-SQL.
How do I convert this from Access into MS-SQL
SELECT TBL_MONTH.L_Month, TBL_MONTH.L_MonthName
FROM TBL_MONTH LEFT JOIN qry_MonthCheck ON TBL_MONTH.L_Month = qry_MonthCheck.L_Month
WHERE (((qry_MonthCheck.L_Month) Is Null));
qryMonthCheck in Access is defined as
SELECT TBL_MONTH.L_Month, TBL_SIGNOFF.SO_YEAR, TBL_SIGNOFF.SO_USER, TBL_SIGNOFF.SO_LOCATION
FROM TBL_MONTH RIGHT JOIN TBL_SIGNOFF ON TBL_MONTH.L_Month = TBL_SIGNOFF.SO_MONTH
WHERE (((TBL_SIGNOFF.SO_YEAR)=[forms]![frm_signoff]![cboyear]) AND ((TBL_SIGNOFF.SO_LOCATION)=[Tempvars]![tmpVarUserLOC]));

It is very much up to personal taste. For tables I use no prefix at all. Or suffix. I prefer plural: categories, products, etc. For junction tables, I drop the plural in the first entity, for instance productcategories. As for the case, many people prefer
initial uppercase, while I go for lowercase only. But initial uppercase has its points, particularly in documentation. I am a staunch advocate of using case-sensitive collation for metadata. I don't see any point in mixing productcategories, Productcategories,
ProductCategories etc. That can only cause confusion.
As for either entities, I don't use views much, and I don't have any prefix for these either. In fact, several views I've been involved used to be tables once upon a time.
If you want to add a marker to the object name, I recommend using a suffix. It is much easier to find objects in the version control system and other browser, when not everything is cluttered on the same letter. For instance, I typically add _sp at the end
of stored procedure names.

Help with a COUNT query...

I have created the following tables:
create table ZONE (
ZoneNo number(2),
State char(3),
PRIMARY KEY (ZoneNo)
create table SCHOOL (
SchoolType char(1),
SchoolNumber number(4),
SchoolName char(40),
SchoolZone number(2),
PRIMARY KEY (SchoolNumber,SchoolType),
FOREIGN KEY (SchoolZone) REFERENCES ZONE
create table TEACHER (
TeacherCode char(5),

FOREIGN KEY (LivesIn) REFERENCES ZONE
create table COMPUTER (
SerialNumber char(10),

RegisteredTo char(5),
PRIMARY KEY (SerialNumber),
FOREIGN KEY (RegisteredTo) REFERENCES TEACHER
My question is, how would i make a COUNT (or similar) query that would display each SchoolName and show the total amount of teachers who work at that school in the second column?

Yes, it needs to join all columns on foreign key.
This is usual, gentle, safety, and universal approach.

Help with doing SELECT sub query within the SET of an UPDATE statement

After doing some research, it appears as if it's possible to use a SELECT subquery in the SET of an UPDATE statement. i did find some examples and here is my code, however when I click the "check" button it's saying the field (my entire select subquery) is unknown and neither in one of the specified tables or defined by a "DATA". Do I have a syntax issue or is there another reason why it's not taking this as a valid statement? Thanks for the help!
LOOP AT IT_DATA
UPDATE /BIC/AZDP_O0140
   SET /BIC/ZCOUNTER = (SELECT COUNT( DISTINCT MATERIAL )
                        FROM /BIC/AZDP_O0140
                        WHERE MATERIAL EQ IT_DATA-MATERIAL
                        GROUP BY MATERIAL).
ENDLOOP.

my Update does indeed have a WHERE clause but because of the issue i'm having, all my criteria in my WHERE is black text in the ABAP editor. The editor doesn't even recognize the keywords "WHERE" or "EQ". Below is my entire statement which contains all WHERE criteria in both the Update and the Subquery, i've just removed it for testing to help simplify the query and eliminate as many other factors as posisble that may be causing problems:
LOOP AT IT_DATA.
   UPDATE /BIC/AZDP_O0140
   SET /BIC/ZCOUNTER = (SELECT COUNT( DISTINCT MATERIAL ) FROM /BIC/AZDP_O0140
   WHERE WHSE_NUM EQ IT_DATA-WAREHOUSE
    AND PLANT EQ IT_DATA-PLANT
    AND /BIC/ZTRAN_NO EQ IT_DATA-TRANS_NUM
    AND DELIV_NUMB EQ IT_DATA-DELIVERY
    AND MATERIAL EQ IT_DATA-MATERIAL
    GROUP BY MATERIAL)
   WHERE WHSE_NUM EQ IT_DATA-WAREHOUSE
    AND PLANT EQ IT_DATA-PLANT
    AND /BIC/ZTRAN_NO EQ IT_DATA-TRANS_NUM
    AND DELIV_NUMB EQ IT_DATA-DELIVERY
    AND MATERIAL EQ IT_DATA-MATERIAL.
ENDLOOP.
i should also mention the sources i found were not within the SAP Library but instead on other third-party ABAP websites. so because i was having issues i wanted to post here to see if anyone else has come up with a working solution. but if this cannot be done i can likely come up with a solution for my needs using multiple internal tables, this would just have been much easier since i can get a query like this to do what i want in SQL Server. Thought i could utilize this in ABAP as well.

Need help with division within a query

Hello all~
I am trying to divide these two columns to get a % of case numbers involving an accident. Im pretty sure you need to use decode to avoid the divide by 0 error but not sure how to implement this within my query. When i run this query below, it gives me the result of "1", which is not correct. Can someone help me please?
Oracle Version 10g
ACCIDENT is a datatype VARCHAR
CASE_NUMBER is a datatype VARCHAR
select to_char(count(ACCIDENT),'999,999,999') as "ACCIDENT",
to_char(COUNT(CASE_NUMBER),'999,999,999')as "CASE NUMBER",
round(ratio_to_report(count(accident))
OVER()*100,2)as "%"
from "PURSUIT"
WHERE ACCIDENT = 'Y'
AND
(:P1_BEG_DATE IS NULL AND :P1_END_DATE IS NULL
OR
pursuit_date BETWEEN to_date(:p1_beg_date,'MM/DD/YYYY') and to_date
(:p1_end_date,'MM/DD/YYYY'))
AND(:P1_TROOP=pursuit.officer_troop OR :p1_troop IS NULL)
AND(:P1_RADIO=pursuit.officer_radio OR :p1_radio IS NULL)
group by case_numberThanks
Deanna

Are you sure that the ANDs and ORs in your WHERE clause will take precedence properly?
Also, if you always select only cases where there has been an accident, what percentage would you like to display? Surely in this case the percentage of cases involving in accident in cases where there was an accident.. is 100%?
as a simpler example
SELECT
accident,
ROUND(RATIO_TO_REPORT(count(*)) OVER() * 100)
FROM
pursuit
GROUP BY
accidentHere's a trick to neaten up those IS NULLs:
SELECT
accident,
ROUND(RATIO_TO_REPORT(count(*)) OVER() * 100)
FROM
pursuit
WHERE
pursuit_date >= COALESCE(:p1_beg_date, pursuit_date) AND
pursuit_date <= COALESCE(:p1_end_date, pursuit_date) AND
officer_troop LIKE :p1_troop AND
offcier_radio LIKE :p1_radio
GROUP BY
accidentTo wildcard a date, simply pass NULL in; the coalesce will replace the null with the pursuit_date from the record (thus the >= and <= becomes true)
To wildcard the troop or the radio, simply pass a '%' symbol as the value of the parameter. If the front end code is already set up to pass nulls, use the COALESCE trick above

Help with aggregate function max query

I have a large database which stores daily oil life, odo readings from thousands of vehicles being tested but only once a month.
I am trying to grab data from one month where only the EOL_READ = 0 and put all of those values into the previous month's query where EOL_READ = anything.
Here is the original query which grabs everything
(select distinct vdh.STID, vdh.CASE_SAK,
max(to_number(decode(COMMAND_ID,'EOL_READ',COMMAND_RESULT,-100000))) EOL_READ,
max(to_number(decode(COMMAND_ID,'ODO_READ',COMMAND_RESULT,-100000))) ODO_READ,
max(to_number(decode(COMMAND_ID,'OIL_LIFE_PREDICTION',COMMAND_RESULT,-100000))) OIL_LIFE_PREDICTION
from veh_diag_history vdh, c2pt_data_history cdh
where vdh.veh_diag_history_sak = cdh.veh_diag_history_sak
and cdh.COMMAND_ID in ('EOL_READ','ODO_READ','OIL_LIFE_PREDICTION')
and vdh.LOGICAL_TRIGGER_SAK = 3
and cdh.CREATED_TIMESTAMP =vdh.CREATED_TIMESTAMP
and cdh.CREATED_TIMESTAMP >= to_date('03/01/2007 12:00:00 AM','mm/dd/yyyy HH:MI:SS AM')
and cdh.CREATED_TIMESTAMP < to_date('04/01/2007 12:00:00 AM','mm/dd/yyyy HH:MI:SS AM')
group by vdh.STID, vdh.case_sak
having count(distinct command_id) = 3
order by OIL_LIFE_PREDICTION)
which gives 5 columns:
STID, CASE_SAK, EOL_READ, ODO_READ, and OIL_LIFE_PREDICTION
and gives me about 80000 rows returned for the above query
I only want one reading per month, but sometimes I get two.
STID is the unique identifier for a vehicle.
I tried this query:
I tried this query which nests one request within the other and SQL times out every time:

order by OIL_LIFE_PREDICTION
so in summary I am trying to select values from the previous month only from those stids where this month's value for EOL_READ = 0
Any ideas.....please help.

You can use row_number() within each stid and each month to determine the first read of each month. Then you can use lag() to get the previous month's reading of the current month's reading is zero.
with all_data as (
select stid,
       case_sak,
       eol_read,
       timestamp,
       row_number() over (partition by stid, trunc(timestamp,'mm') order by timestamp) AS rn
from veh_diag_history
select stid,
       case_sak,
       case
         when eol_read = 0
           then lag(eol_read) over (partition by stid order by timestamp)
         else eol_read
       end as eol_read
from all_data
where rn = 1;

Help with Finding Duplicate records Query

HI,
I am trying to write a query that will find duplicate records/cases.
This query will be used in a report.
So, here are the requirements:
I need to find duplicate cases/records based on the following fields:
DOB, DOCKET, SENT_DATEI was able to do that with the following query. The query below is able to give me all duplicate records based on the Criteria above
SELECT      DEF.BIRTH_DATE DOB,
           S.DOCKET DOCKET,
           S.SENT_VIO_DATE SENT_DATE, COUNT(*)

AND       S.CASE_TYPE_CODE = 10
GROUP BY DEF.BIRTH_DATE, S.DOCKET, S.SENT_VIO_DATE
HAVING COUNT(*) > 1;
//I AM GOING TO CALL THIS QUERY 'X'Now, the information to be displayed on the report: defendants Name, DOB, District, Docket, Def Num, Sent Date, and PACTS Num if possible.
The problem that I need help on is how to combine those queries together (what I mean is a sub query). the 'X' query returns multiple values. please have a look at the comments on the query below to see what I'm trying to achieve.
here is the main query:
SELECT      INITCAP(DEF.LAST_NAME) || ' ' || INITCAP(DEF.FIRST_NAME) || ' ' || INITCAP(DEF.MIDDLE_NAME) DEFENDANT_NAME,
        DEF.BIRTH_DATE DOB,

I am using Oracle 11g, and sql developer.
if my approach doesn't work, is there a better approach ?

If I got it right, you want to join table USSC_CASES.DEFENDANTS to duplicate rows in USSC_CASES. If so:

SELECT INITCAP(DEF.LAST_NAME) || ' ' || INITCAP(DEF.FIRST_NAME) || ' ' || INITCAP(DEF.MIDDLE_NAME) DEFENDANT_NAME,

if your goal is to optimize your query for initial response time, you may want to use the former query, with the scalar subquery, because Oracle Database would have to get just the first row from DEPT, run the scalar subquery (select count...) against EMP to get the count, and then return it. The process for returning that first row would be very fast.

The corollary to this that was not explicitly mentioned in the article that I can see is that this probably comes at the expense of the time taken to return all the rows which can then take longer.

Need some help with a counting function

Hello,
I use a simple sheet to organize the timetable of my patients. Now I'd like to count how many different patients I attend, without counting a patient twice if I attend him twice a week for example. My sheet looks like this:
Mon
Tue
Wed
Thu
John
Steve
John
Wesley
Mary
Harry
Deborah
Peter
Arnold
Carol
Chris
Mary
Sarah
Karen
Karen
Carol
Larry
Peter
So the answer would be 13, because I attend 13 different patients a week. Fields in blank should no be counted, the cell contend changes frequently.
A friend of mine tried to help me with a countif function but it didn't work out for me, it would count the fields left blank too.
Any idea?
Thanks, gabriel

Hi Gabriel,
Here's another, more generalized, approach that doesn't need adjusting for maximum number of visits/week at the cost of just a few more formulas. But only two tables!
Formula in A2 and copied down:
=ROUNDUP((ROW(cell)−1)÷$B$27,0)
Formula in B2 and copied down:
=IF(MOD(ROW(cell)−1,$B$27)=0,$B$27,MOD(ROW(cell)−1,$B$27))
The formula in C2 and copied down:
=OFFSET(Schedule::$A$1,0,B−1)
The formula in D2 and copied down:
=IFERROR(OFFSET(Schedule::$A$1,A2,B2−1,rows,columns),"")
The formula in E2 and copied down:
=IF(AND(D2≠0,LEN(D2)>0),COUNTIF($D$1:D2,D2),"")
The formula in F2 and copied down:
=IFERROR(IF(E=1,1,""),"")
The formula in F27: =SUM(F)
The value in B27 is 4, the number of day columns in the Schedule table. You would change that if you increase or decrease the number of days on which you see patients.
Column C is cosmetic, not needed in the calculation.
The error triangle means all of the cells in the Schedule table are already accounted for in the rows above.
Probably more compact ways to do this but it gets the job done.

Need Help with Creating the SQl query

Hi,
SQL query gurus...
INFORMATION:
I have two table, CURRENT and PREVIOUS.(Table Defs below).
CURRENT:
Column1 - CURR_PARENT
Column2 - CURR_CHILD
Column3 - CURR_CHILD_ATTRIBUTE 1
Column4 - CURR_CHILD_ATTRIBUTE 2
Column5 - CURR_CHILD_ATTRIBUTE 3
PREVIOUS:
Column1 - PREV_PARENT
Column2 - PREV_CHILD
Column3 - PREV_CHILD_ATTRIBUTE 1
Column4 - PREV_CHILD_ATTRIBUTE 2
Column5 - PREV_CHILD_ATTRIBUTE 3
PROBLEM STATEMENT
Here the columns 3 to 5 are the attributes of the Child. Lets assume that I have two loads, One Today which goes to the CURRENT table and one yesterday which goes to the PREVIOUS table. Between these two loads there is a CHANGE in the value for Columns either 3/4/5 or all of them(doesnt matter if one or all).
I want to determine what properties for the child have changed with the help of a MOST efficient SQL query.(PARENT+CHILD is unique key). The Database is ofcourse ORACLE.
Please help.
Regards,
Parag

Hi,
The last message was not posted by the same user_name that started the thread.
Please don't do that: it's confusing.
Earlier replies give you the information you want, with one row of output (maximum) per row in current_tbl. There may be 1, 2 or 3 changes on a row.
You just have to unpivot that data to get one row for every change, like this:
WITH     single_row AS
     SELECT     c.curr_parent
     ,     c.curr_child
     ,     c.curr_child_attribute1
     ,     c.curr_child_attribute2
     ,     c.curr_child_attribute3
     ,     DECODE (c.curr_child_attribute1, p.prev_child_attribute1, 0, 1) AS diff1
     ,     DECODE (c.curr_child_attribute2, p.prev_child_attribute2, 0, 2) AS diff2
     ,     DECODE (c.curr_child_attribute3, p.prev_child_attribute3, 0, 3) AS diff3
     FROM     current_tbl    c
     JOIN     previous_tbl   p     ON c.curr_parent     = p.prev_parent
                            AND c.curr_child     = p.prev_child
     WHERE     c.curr_child_attribute1     != p.prev_child_attribute1
     OR     c.curr_child_attribute2     != p.prev_child_attribute2
     OR     c.curr_child_attribute3     != p.prev_child_attribute3
,     cntr     AS
     SELECT     LEVEL     AS n
     FROM     dual
     CONNECT BY     LEVEL <= 3
SELECT     s.curr_parent     AS parent
,     s.curr_child     AS child
,     CASE     c.n
          WHEN 1 THEN s.curr_child_attribute1
          WHEN 2 THEN s.curr_child_attribute2
          WHEN 3 THEN s.curr_child_attribute3
     END          AS attribute
,     c.n          AS attribute_value
FROM     single_row     s
JOIN     cntr          c     ON     c.n IN ( s.diff1
                                , s.diff2
                                , s.diff3
ORDER BY attribute_value
,            parent
,            child

Help with SYSDATE in SQL query

Hi all,
I'm trying to select some data from table base on SYSDATE. The below query does not return any data.
My query is:
select count(TICKET_ID) "ECEMEA" from QTMT_TICKETS where STATUS_ID=1 and TEAM_ID=3 and RECEIVED_DATE=sysdate
Could you please let me know, why this does not work? Date format in my application is: DD-MMM-YY (16-AUG-12). In the database the dates are stored in this format: MM/DD/YYYY (08/25/2012). Does it mean, that I have to play with the format?
Please let me know.
Thank you and best regards,
Vladimir

Assuming RECEIVED_DATE is actually of type DATE (and it should be), then no format is applied to dates until they are converted for display, however there may be a time component stored that is not visible in the default date display format. Try
select count(TICKET_ID) "ECEMEA"
from QTMT_TICKETS
where STATUS_ID=1
and TEAM_ID=3
and RECEIVED_DATE >= trunc(sysdate)
and RECEIVED_DATE < trunc(sysdate) + 1

Help with a "save as" query or an alternative suggestion

Hi all
Hope someone can spread some light on this for me, im rather new to using adobe pro - and never ventured into java scripts as yet..
I have created a pdf document with various text boxes within the document. The document will be pushed out to external users who will only have access to adobe reader.
My query is this:
I've created a save button, but can the file name automatically be set to include the data in one of the text fields. I still want the user to chose where to save the document but want the file name to be fixed to the data in the relevant text box.
If it can be done is it a relatively straight forward procedure.
If this is not possible, then as an alternative is it possible ible to create maybe a Warning or pop up box after clicking on the "save as" button to prompt the user to save with a different file name to avoid saving over previous versions etc.
Again if this is this possible, is it difficult to achieve?
Many thanks in advance for any help!
Cheers
Adam

This tutorial contains a lot of information about saving a file in Acrobat
using JavaScript:
http://acrobatusers.com/tutorials/how-save-pdf-acrobat-javascript
The bottom line is that in order to do it you must have a script installed
on the local machine.
The alert is possible, but at the moment it is displayed the user can no
longer cancel the save command, so you can't really tell them to cancel it
at that time...

Help with supply and demand query using monthly buckets

I'm working on a query bound for Discoverer which pulls the aggregated supply and demand for an item and buckets it into months. So for any given item, I need to show the item, onhand, cost, aggregated supply (planned orders, requisitions, pos), and aggregated demand (planned order demand, jobs) - all bucketed by months.
The code below works okay to find all of the data for July, but I also need to show August and September. I'm thinking I could use a union but am reluctant because the query already runs kind of slow and I'm not sure if I'm on the right track.

Hi,
Six things:
(1) Where are the one-to-many relationships between your tables? If a single row in mtl can match two (or more) rows in mrp, and can also match two (or more) rows in wip, then it looks like, when you join both of them them, you'll have a chasm trap, that is, you'll get all the matching rows from mrp paired with all matching rows from wip. Are you sure your existing query is producing the right results?
Are there one-to-many relationships with the other tables in your original query?
(2) Are your DATEs always at midnight? If not, avoid using BETWEEN and LAST_DAY for DATE comparisons: otherwise you'll miss everything between 00:00:01 and 23:59:59 on the last day.
That is, instead of
and     mrp.new_due_date(+) BETWEEN :Month AND LAST_DAY(ADD_MONTHS(:Month,2))ypou should say
and       mrp.new_due_date (+)     >= :Month
and       mrp.new_due_date (+)     < ADD_MONTHS (:Month, 3)(3) The basic way to pivot the months of mrp_due_date is:
SELECT    ...
,       NVL ( SUM ( CASE
                 WHEN mrp.new_due_date >= :month
                 AND   mrp.new_due_date < ADD_MONTHS (:month, 1)
                 THEN mrp.quantity_rate
                END
           , 0
           )          AS mrp_qty_0
,       NVL ( SUM ( CASE
                 WHEN mrp.new_due_date >= ADD_MONTHS (:month, 1)
                 AND   mrp.new_due_date < ADD_MONTHS (:month, 2)
                 THEN mrp.quantity_rate
                END
           , 0
           )          AS mrp_qty_1When you do this, do not GROUP BY TRUNC (mrp.new_due_date, 'MM').
The code above does two months: I'm sure you get the idea for how to do more.
To get dynamic column headings (such as Jun_2009 or "2009-06" instead of the generic mrp_qty_o) requires dynamic SQL. The best way to do dynamic SQL depends on the tool that is producing the query (e.g. SQL*Plus). What are you using? Are you willing to change, if it helps?
(4) Displaying separate columns from one row as a single column on multiple rows is called unpivoting. How badly do you want to do that? Your query would be simpler and faster if the output had only one row per group (rather than one row for mrp_qty and another row for wip_wty). That one row could have six columns (e.q. June_mrp, June_wip, July_mrp, July_wip, August_mrp and August_wip) instead of three. Depending on your front-end tool, you might even be able to wrap the single row of output so that it always appeared as two rows, each with three columns.
(5) Sorry I told you to do
and     mrp.order_type_text(+) in (...)I never use the + outer-join notation any more, so I forgot about the ORA-01719 error. There's no problem having an outer-join condition like that using ANSI notation. (One more reason to switch.)
(6) As you noticed, this site doesn't like to print the <> inequality operator, even inside tags.
Use the equivalent != operator instead, when posting on this site.

Continuation-Please help with a complex sql query

Hi all,
Thanks a lot for your suggestions and inputs in the last thread of this post.
With the help of your suggested approach,i went ahead and was able to get some more data in the format as needed..I worked on gradually adding one table after another exactly as the data is required stepwise.But,still I am facing issues with displaying them.
there are many issues I am not able to do and would appreciate if you please have a look at my latest modified SELECT given below and help me writing it to get the display as needed.
Below,is the attempted query i tried out using your inputs.But,am stuck and need your help in writing it.
**Here,there is 1 ->MANY lines for the t_objective_id--->This has many learning_record_ids which i want to group by the unique objective_id.

If we see the outer SELECT ---then one of the main issues is for EACH t_objective_id----->There are n learning_record_ids.
But,this select only shows 1 learning_record_id for each objective_id which is wrong.
Similarly,the data displayed isnot proper.
Below is the way I am getting the data now from the above SELECT.
Note:- FIRSTNAME is not correctly displayed.
FIRSTNAME     EMPLID     TPLAN_NAME     TPLAN_ID     ACTIVITIES     ACTIVITIES_1

Help with a simple XMLTable query

Newbie Oracle XML developer here and need a little guidance on how to retrieve multiple records in an xmltype table using xmltable.
My document in the xmltype table looks like this:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<echoems:ECHOMetrics xmlns:echoems="http://myURL/myFilename.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://myURL/myFilename.xsd
http://myURL/myFilename.xsd">
<OrderMetrics>
<OrderItemMetric>
<requestor>user1</requestor>
<product>123</product>
</OrderItemMetric>
<OrderItemMetric>
<requestor>0.0.0.0</requestor>
<product>ABC</product>
</OrderItemMetric>
<OrderItemMetric>
<requestor>user3</requestor>
<product>XYZ</product>
</OrderItemMetric>
</OrderMetrics>
</echoems:ECHOMetrics>
I want to get all the products:
Product
123
ABC
XYZ
I know to use XMLTable but am not sure how exactly to write it. If just one record, the following worked fine:
select extractvalue
(object_value,
'echoems:ECHOMetrics/OrderMetrics/OrderItemMetric/product',
'xmlns:echoems="http://myURL/myFilename.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"'
) object_value
from echoXML;
But with multiple records, I'm trying XMLTable but can't get it right. Trying something like this:
select m.product
from echoXML3
xmlTable(
(object_value,'echoems:ECHOMetrics/OrderMetrics/OrderItemMetric/*','xmlns:echoems="http://myURL/myFilename.xsd')
passing object_value
COLUMNS
product varchar2(85) path 'product') m;
Thanks in advance for any help on this.

One more question. Instead of putting the xml doc in the query, how do I reference it from the xmlType table?
You have:
select *
from xmltable
'//OrderMetrics/OrderItemMetric'
passing xmltype(
'<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<echoems:ECHOMetrics xmlns:echoems="http://myURL/myFilename.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://myURL/myFilename.xsd">
<OrderMetrics>
<OrderItemMetric>
<requestor>user1</requestor>
<product>123</product>
</OrderItemMetric>
<OrderItemMetric>
<requestor>0.0.0.0</requestor>
<product>ABC</product>
</OrderItemMetric>
<OrderItemMetric>
<requestor>user3</requestor>
<product>XYZ</product>
</OrderItemMetric>
</OrderMetrics>
</echoems:ECHOMetrics>')
columns
prod varchar2(20) path 'product',
requestor varchar(50) path 'requestor'
However, the xmlDocument is already in an xmlType table called echoXML3 based on the xsd. I'm just trying to query it to get a relational result set. How, in the query above, do I replace the hardcoded xmlDoc with the xmlDoc located in my xmlType table?
I thought maybe something like this but it's not working:
select *
from xmltable
'//OrderMetrics/OrderItemMetric'
passing xmltype(select value(e)
from echoXML3,
TABLE(xmlsequence(extract(object_value,'echoems:ECHOMetrics/OrderMetrics/OrderItemMetric/*','xmlns:echoems="http://myURL/myFilename.xsd'))) e)
columns
prod varchar2(20) path 'product',
requestor varchar(50) path 'requestor'
