Reg: Doubt in XQuery FLWOR expression

Hello Experts,

I have a XML like this-

< root >

< Reports >

< report >

< ReportName > ABCM < / ReportName >

. . . other details...

< / report >

< report >

< ReportName > XYZZ < / ReportName >

. . . other details...

< / report >

< report >

< ReportName > ABCXO < / ReportName >

. . . other details...

< / report >

< report >

< ReportName > COMO < / ReportName >

.. .other details...

< / report >

< / Reports >

< / root >

I have try it like this.

Select x1.*

Of

test_xml,

XMLTABLE)

' for $i in Root/reports/reports

where $i / ReportName in ('ABCM', 'ABCXO')

Return $i"

in passing test_xml.dx

columns

slno for the ordinalite,

path of varchar2 (15) report_name 'NomRapport. "

sequence_number number path "SequenceNumber".

) x 1

;

My doubt is in the red part above.

I want to go get the details only for reports whose name start with 'ABC '. Even $i / ReportName as 'ABC%' will raise an error

ORA-19114: XPST0003 - error during parsing of the XQuery expression:

LPX-00801: error of XQuery syntax to "like".

2 where $i / ReportName as 'ABC% '.

  • How to create the SQL filter using XQuery FLWOR

    It is possible to create such a FLWOR expression that will be pushed down to SQL uses 'IN SQL"filtering?

    Assuming that the following function declaration:

    declare function tns:filterOnLevels($levels_as_xs:double+) {...

    I would like to create FLWOR expression that will be pushed down to this SQL:
    Select * from LEVELS where level IN ($levels)

    And tns:filterOnLevels (1,2,3) should run statement with ' where level IN (1,2,3). Type SQL filtering owe be lowered to SQL, because the execution of the query without constraint could train with too many records.

    This expression is possible to do in XQuery/XQSE or perhaps other extensions of fn - bea?

    I'm working on ODSI/Workshop 10.3 and Oracle 10 g.

    ODSI uses multiple GOLD instead of IN because optimizers (1) rewrite 'IN' as several GOLD anyway. and (2) OR is more general than 'IN,' since 'IN' can handle that (a) equal; and (b) a single multiple-column, while GOLD can also manipulate inequalities and several columns.

    In your example...

    declare function tns:filterOnLevels($levels_as_xs:double*) {(: use ' *' instead of '+' here, the optimizer will appreciate :))}

    for $l in $levels
    for $LEVELS in LEVELS()
    where $LEVELS/LEVEL = $l
    return
    $LEVEL

    If you look at the generated query plan, it should contain...

    SELECT = from LEVELS including LEVEL? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =? LEVEL or =?

  • Reg: Difference between XQuery and XPath:

    Hi Experts,

    I tried google on this subject and read a few articles but found no adequate explanation or may not be able to understand.

    Of http://stackoverflow.com/questions/924551/difference-between-xpath-xquery-and-xpointer

    In general, XPath is a language used to locate accurate XML nodes in a DOM succinctly. XQuery is a superset of XPath which also provides FLWOR sytnax, which is similar to SQL. Finally, XPointer includes XPath, but also provides a simple model to address based on the post.

    It is also a good read - what is XQuery?

    Any other pointers? According to my understanding, both are used for the XMLs, like the SQL query for relational data. But if the two are similar, what is the reasoning behind the two different technologies?


    Please share your ideas in this regard.

    Kind regards

    Typing?

    http://www.w3.org/TR/xpath20/#ID-types

    "Transforming data" - you mean CFDS on XML data, right?

    More like SQL, but there is no strict equivalence.
    Given that XML is self-descriptive language, transforming one XML document into another also means the metadata change.
    This is where the concept of XML schema.

    What language do technical FLWOR come - XQuery or XPath?

    XQuery.

    For example:
    for $i in/root/point [1] / value
    where $i/@uom = 'kg '.
    Return to {data ($i)}

    applied to this XML document:

     
        123
     
     

    will return this sequence:

    123

    Here, / root/point [1] / value is an XPath expression (which is also an XQuery expression) but the construction of FLWOR is strictly XQuery.

  • Reg: Doubt dbms_scheduler

    Hi Experts,

    I have the script below-

    (a) Proc_2 uses CREATE_JOB to call proc_1. In this case, I don't see the exit for ' *' and ' =' in my console dbms_output. But, the good works of the Insert (insert only once).

    (b) if I Uncomment RUN_JOB, there are 2 INSERTS that passes for the same data, and I can see the outputs ' *' and ' =' in my console output - once printed.

    {package_x}

    PROC_1 {}

    I'm in (slider)

    loop

    dbms_output.put_line('***');

    INSERT INTO table_x values (i.some_value);

    dbms_output.put_line('===');

    end loop;

    commit;

    }

       proc_2 {}

    dbms_scheduler.create_job ('Task1', proc_1);

    -/ / dbms_scheduler.run_job ('job1');

    }

    }

    No idea why this phenomenon occurs? I haven't worked a lot with planners, but assumes that CREATE_JOB is called to step (a).

    Please notify.

    No idea why this phenomenon occurs? I haven't worked a lot with planners, but assumes that CREATE_JOB is called to step (a).

    Time to read the manual and then, isn't?

    RUN_JOB performs the work in an interactive way, by default in your current session. That's why you can see DBMS_OUTPUT buffer.

    -Running a task immediately. If use_current_session is TRUE the job is run the

    -the user's current session. If use_current_session is set FALSE labor is running the

    -background by a slave of dedicated work.

    PROCEDURE run_job)

    job_name IN VARCHAR2,

    use_current_session IN DEFAULT BOOLEANTRUE,

    event_message IN SYS. ANYDATA DEFAULT NULL);

    CREATE_JOB (assuming you activate it) will submit JOB1 to be run as a background process.

    If you call RUN_JOB immediately after, JOB1 still exists in the dictionary (assuming once again it is auto-dropable), and runs a second time.

    http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb_xquery.htm

    Also, as you should know by now, this kind of questions belong to the forum DB XML or XQuery forum (for a general discussion of the language).

  • XQuery does not return results in 10.2.0.4, works on 10.2.0.5

    I have a statement Xquery which works as expected on Oracle 10.2.0.5 but returns no results on Oracle 10.2.0.4.

    What is the result of a query that is poorly written? A bug in 10.2.0.4?
    Is it possible to rewrite the query so that is done the work on 10.2.0.4?

    TestCode:
    declare

    10.2.0.5 strategic outcome:
    brtachtergrondkaart
    top10nl
    BGT

    It is indeed strange.

    I can reproduce on 10.2.0.4 and follows seems to remedy:

    (1) containing the list of columns in the SELECTION, instead of t.*:

       -- Select layers with TileMatrixSet EPSG:28992
   cursor c_layer(p_xml xmltype) is
      select t.title, t.format, t.style
        from xmltable(

    or,

    (2) with the help of a FLWOR expression extended:

    for $d in //Layer
where $d/TileMatrixSetLink/TileMatrixSet = "EPSG:28992"
return $d

    You may have already noticed, but the problem only occurs in a context of PL/SQL.
    The same query to run from SQL is OK.

  • XPath to capture nodes between two nodes

    Hi all

    I met a problem a seemingly simple challenge of mine.

    I have the following xml code.

    Basically, I would like to capture the text between the begin-end blocks

    <? XML version = "1.0" encoding = "UTF-8"? >

    < document >

    < body >

    < paragraph >

    < run >

    < fld type = 'start' / >

    < / run >

    < run >

    < text > SAMPLE < / text >

    < run >

    < fld type = 'end' / >

    < / run >

    < run >

    < text > TEXT UNWANTED SOME < / text >

    < / run >

    < / paragraph >

    < paragraph >

    < / run >

    < / body >

    < / document >

    So far, what I came up with is:

    WITH temp AS (

SELECT x.*

      ,XMLTABLE('//*/paragraph/run[fld/@type="begin"]/following-sibling::run[following-sibling::run[fld/@type="end"]]/text'
                PASSING temp.xml_template
                COLUMNS res varchar2(100) PATH '.'
               )x

    Result:

    RES

    SAMPLE

    FIELD

    SAMPLE

    FIELD2

    SOME UNWANTED TEXT

    SAMPLE

    FIELD3

    Unfortunately what I wrote XPath is not good enough, because with regard to the text between the two blocs of start-end it still captures the unwanted text.

    My XPath knowledgege dept unfortunately not so I would appriciate annything you can help me with even an idea could get through on the edge.

    Thank you

    Steve

    Steve,

    XQuery can help in this case:

    SELECT x.*
FROM temp
   , XMLTABLE('for $begin in /document/body/paragraph/run[fld/@type="begin"]
               let $end := $begin/following-sibling::run[fld/@type="end"][1]
               return $begin/following-sibling::run[. << $end]'
       PASSING temp.xml_template
       COLUMNS res varchar2(100) PATH 'text'
     ) x  ;

    Explanation:

    This FLWOR expression traverses all nodes 'start' in the document, finds the corresponding node of the 'end' and returns the sequence of "run" nodes follows 'begin' and above 'end '.

    If you want to concatenate all the fragments of text in a block, you can also do it directly, like this:

    for $begin in /document/body/paragraph/run[fld/@type="begin"]
let $end := $begin/following-sibling::run[fld/@type="end"][1]
return string-join($begin/following-sibling::run[. << $end]/text, "")

    She's going back 3 ranks:

    RES

  • Please help to read the XML with XMLTable

    Hi gurus,

    I'm not very familiar with XML parsing. It seems to me that it should be very easy to get the data. For some reason, I'm having a problem to get the data.

    SELECT *.

    Regarding your suggestion, I've never used the syntax of FLWOR. I'll try to implement if I can make it work.

    "FLWOR is the abbreviation of ' for Let's where Order by Return" and refers to the full form of an XQuery query expression.

    Do you think it would be faster than the way I have the values?

    You have used a FLWOR expression (the 'for' + 'return' part of it) in this post: Re: Please help to read the XML with XMLTable

    And I have already said: do not use in this case.

    Faster or slower isn't the point. Oracle will evaluate the expression in the same way.

    But from a maintenance point of view, it's obviously much easier to use a simple XPath expression like this:

    /DT:GetJrShowCustomerHeifersResponse / dt:GetJrShowCustomerHeifersResult / dg:diffgram/DocumentElement/JrShowCustomerHeifers

  • How to create indexes on the ordered collection of XMLTYPE table?

    I use Oracle 11.2.0.2.

    Basically, my XML documents have a 3-level hierarchy:

    + - param [1: n]

    I try to create indexes on the tables of the orderly collection, but cannot get the right syntax...

    I created a table with an XMLType object-relational column:

    CREATE TABLE T_C_RMP_MNTRNG_XML_FULL_IL4 (
  MESSAGE_ID NUMBER(22,0) NOT NULL ENABLE,
  XML_EVAL_ID NUMBER(22,0),
  VIN7 VARCHAR2(7 BYTE),

  CSC_SW_VERSION VARCHAR2(100 BYTE),
  RECEIVED DATE,
  XML_CONTENT SYS.XMLTYPE ,
  DWH_LM_TS_UTC DATE NOT NULL ENABLE,
  CONSTRAINT PK_C_RMP_MNTRNG_XML_FULL_IL4 PRIMARY KEY (MESSAGE_ID)
) NOLOGGING TABLESPACE CATALOG
VARRAY "XML_CONTENT"."XMLDATA"."action" STORE AS TABLE "T_OR_MON_ACTION" (
  NOLOGGING TABLESPACE "CATALOG"
  VARRAY "param" STORE AS TABLE "T_OR_MON_ACTION_PARAM" (
  NOLOGGING TABLESPACE "CATALOG"
  ) RETURN AS LOCATOR
) RETURN AS LOCATOR
XMLTYPE XML_CONTENT STORE AS OBJECT RELATIONAL XMLSCHEMA "http://mydomain.com/cs.xsd" ELEMENT "monitoring";

    I execute the SELECT statement:

    SELECT EVENT_ID, ACTION_SUB_ID, MESSAGE_ID, ACTION_TYPE, UNIXTS_TO_DATE(ACTION_TIMESTAMP) ACTION_TIMESTAMP
FROM T_C_RMP_MNTRNG_XML_FULL_IL4, 
XMLTABLE( 
  'for $i1 in /monitoring ,

    How can I create an index on these tables of the ordered collection to improve performance?

    I found the example at http://docs.Oracle.com/CD/E11882_01/AppDev.112/e23094/xdb_rewrite.htm#ADXDB5859 but am not able to apply to this particular case...

    Thank you in advance...

    If the schema is not annotated and XS: Integer and XS: String are mapped to types of data NUMBER and VARCHAR2 (4000), so you must use in your query to avoid typecasting unnecessary operations.

    You must also use XMLTABLEs chained when accessing a parent/child instead of a FLWOR expression relationship, otherwise the CBO cannot rewrite the XQuery query correctly (maybe it's fixed in the latest version).

    If you make these changes, the plan should show the cleaner predicates:

    SQL > SELECT EVENT_ID, MESSAGE_ID, ACTION_TYPE, ACTION_SUB_ID, ACTION_TIMESTAMP

    2 FROM test_table

    3 XMLTABLE ('/ monitoring ')

    4 COLUMNS XML_CONTENT OF PASSAGE

    5 WAY of VARCHAR2 (4000) EVENT_ID "ID."

    6 actions for XMLTYPE PATH 'action '.

    (7) T1,

    8 XMLTABLE ('/ action')

    Shares of PASSAGE 9 COLUMNS

    NUMBER of ACTION_SUB_ID 10 PATH "actionSubId."

    11 PATH of VARCHAR2 (4000) ACTION_TYPE "type."

    12 WAY of NUMBER ACTION_TIMESTAMP 'time '.

    (13) T2

    14 WHERE EVENT_ID IS NOT NULL

    15 AND ACTION_SUB_ID IS NOT NULL

    16;

    Now, if it is still necessary, everything boils down to choosing a technique for index NULL values:

    -composite index with a column not zero or constant

    -FBI

    -bitmap image

    Choose the one that best fits your data, the selectivity and activity on the tables.

  • OSB tuning issues

    Hi all!
    After some problems with the larger requests, I need to investigate the flow of my message, and I have a few questions.

    1. so if I use $body to assign to the OriginalBody variable at the beginning of the flow - it creates copy full size in memory so if the body is 5 MB, there will be additional 5 MB assigned?

    2. often, I have a lot to assign multiple actions, as
    Assign $ Element/body [1] / id/text () to the variable Id
    Assign the $body / Element [1] / name/text () in the name of the variable
    etc.
    However, in the tuning OSB doc, I see:
    >
    Created context variables using an action to assign are converted to the XmlBeans and then comes back to the native format of XQuery for the next XQuery. Several actions 'Assign' can be reduced to only one action attribute using a FLWOR expression. Intermediate values can be created using "let" declarations. Avoiding variable creation of context redundant eliminates the overhead associated with internal data format conversions. This advantage must be balanced with the visibility of the code and re-use of variables.
    >
    I don't understand this 'Assign unique action using a FLWOR expression"- any example?

    Thanks again

    1. so if I use $body to assign to the OriginalBody variable at the beginning of the flow - it creates copy full size in memory so if the body is 5 MB, there will be additional 5 MB assigned?

    Yes. When running, the flow of proxy runs as a set of java objects. And variables created in the flow of the messages will end up also being created as objects in memory to the jvm.
    Thus, the more variables created, more the memory footprint.

    'simple action to assign by using a FLWOR expression' - no matter what example?

    An example will be to implement the logic of complex Web - rather than use the actions of the OSB of loop and several actions with-right/replace, you can use the extract below using an assign action+ to perform the same tasks.

    for $v in $doc / / video
    where $v/year = 1999
    return $v/title

    You can get other examples @ http://www.stylusstudio.com/xquery_flwor.html who use FLWOR expressions.

    I hope this helps.

    Thank you

  • Use the attribute as a set of data and analysis of these data

    Hello world
    I present below a challenge (a little) with the use of attributes in XQuery. Consider the following XML document:

    < showroom >
    < car id = "1" >
    < name > Clio < / name >
    < family > Renault < / family >
    < / car >
    ...
    < id car = "n" >
    < name > Q5 < / name >
    Audi > family < < / family >
    < / car >
    < / showroom >

    Each customer of the showroom is identified by a unique Id (for example, 1,2,3,...). Then, I want to add some data to my XML document that must represent, for each car, all of the IDs of all the customers who have rented this car.
    The desired XML document might look like this:

    < showroom >
    < car id = "1" >
    < name > Clio < / name >
    < family > Renault < / family >
    + * < history > * +.
    + * < client id = "2" / > * +.
    + * < client id = "23" / > * +.
    + * < / history > * +.
    < / car >
    ...
    < id car = "n" >
    < name > Q5 < / name >
    Audi > family < < / family >
    + * < history > * +.
    + * < client id = "56" / > * +.
    + * < / history > * +.
    < / car >
    < / showroom >

    However, using elements to represent the historic location, size of the document will increase considerably.
    As I only use IDs of the IEN, y at - it a way to represent historical data using only the attributes? +.
    In the following document, id of the IEN are represented, as a whole, through the +@history+attribute:
    < showroom >
    < car id = '1' history = '2.23' >
    < name > Clio < / name >
    < family > Renault < / family >
    < / car >
    ...
    < id car = history of "n" = "56" >
    < name > Q5 < / name >
    Audi > family < < / family >
    < / car >
    < / showroom >

    However, y at - there no way to check if a given id = 'x' car was rented by a customer Id = 'y'? +.
    Does anyone know how to represent historical data (sequence of identity of customers), using only the attributes and how to search for a given id of customer as explained above?
    Please suggest. I appreciate your help.

    OK, I thought that you already have a document that stores the relationship between customers and cars.

    Here is an example that will insert or update the attribute of history:

    let $carId := 3
let $clientId := 56
return
 copy $doc := fn:doc("c:\dev\xml\showroom.xml")
 modify (
  for $i in $doc/showroom/car
  where $i/@id = $carId
  return if (exists($i/@history))
          then replace value of node $i/@history with concat($i/@history,",",$clientId)
          else insert node attribute history {$clientId} into $i
 )
 return $doc

    However, if we are reasoning in terms of standardization, it is better to have these relationships stored as separate elements, be it in the showroom or another XML document. Then you could simply perform a join or use a nested FLWOR expression to retrieve historical data.

    To check if the attribute contains a given customer id:

    let $carId := "3"
let $clientId := "56"
let $doc := fn:doc("c:\dev\xml\showroom.xml")
return fn:exists(fn:tokenize($doc/showroom/car[@id=$carId]/@history, ",")[.=$clientId])

    She will return a Boolean value.

    If we have not been through any of this before? Seems that Yes.

    Declare a namespace prefix is fine, but you do not actually use.

    In any case, use a declaration of default namespace in this case.

    Your delete operations can also be integrated in the XQuery Update expression entirely:
