PL/SQL :: Referencing Element In Nested Collection
Jun 27, 2013
I have a table called dept table with nested collection as below. Nested Table Collection:
create or replace
type courselist as table of varchar2(64) Table Using Nested Table Collection:
CREATE TABLE "FCSDWH_STG"."DEPT"
( "NAME" VARCHAR2(20 BYTE),
"DIRECTOR" VARCHAR2(20 BYTE),
"OFFICE" VARCHAR2(20 BYTE),
"COURSES" "FCSDWH_STG"."COURSELIST"
) Content Of Table:NameDirectorofficecoursesAccountingJames CharlesUNOFCSDWH_STG.COURSELIST('natural science','chemistry','Computer Science','Computer Science')
I am trying to select and print an element from nested table collection using below plsql block.
MY_COURSE VARCHAR2(64 CHAR);
BEGIN
SELECT courses INTO MY_COURSE FROM TABLE(SELECT COURSES FROM DEPT) where courses='chemistry';
DBMS_OUTPUT.PUT_LINE(MY_COURSE);
END; Error Message:
PL/SQL: ORA-00904: "COURSES": invalid identifier
I'm trying to sort a collection in a nested table in PL/SQL so these value can be used later for a display and for export to Excel. The sort is failing.
-- PLS-00642: local collection not allowed in SQL statements
-- PL/SQl: ORA-00902: invalid datatype
The error message are also noted below in the code on the line that fails.
A quick overview of this code- Using a nested table MyNestedTable the values from several select queries are combined into MyRecordsetZero using CURSOR, and MULTISET UNION. I'm trying to either sort MyRecordsetZero or populate MyRecordsetSorted with the sorted values for futher use.
IMPORTANT: The code is running in an enviroment that does not have permission to create.
I'm having a bit of a problem getting the syntax of a trigger right. Unfortunately, I have no DBAs locally, I use some third party software, and for reasons beyond my understanding, I have been told to use triggers, and not stored procedures, so I'm running with it.
The set up:
STRUCTURES table: contains several columns, one of which is the unique ID column. ASSAY table: contains several rows, also with the same ID column, but can have more than one row per ID (several assays per compound). One column is XC_ASSAYS.
The idea of the trigger is basically: When a row in the ASSAYS table is updated, pull out the ID of the row, then calculate the average of the XC_ASSAYS columns for those rows, and report it to the STRUCTURES.XC_ASSAY column for that row ID.
My best attempt thus far results in compilation errors.
CREATE TRIGGER INHIB_W_ALA_TR AFTER INSERT OR UPDATE ON ASSAYS FOR EACH ROW BEGIN UPDATE STRUCTURES SET XC_ASSAY = (SELECT AVG(XC_ASSAY) FROM ASSAYS WHERE ASSAYS.ID = :NEW.ID) WHERE STRUCTURES.ID = :NEW.ID END; /
The resulting errors are: LINE/COL ERROR -------- ----------------------------------------------------------------- 2/1 PL/SQL: SQL Statement ignored 2/190 PL/SQL: ORA-00933: SQL command not properly ended 12/0 PLS-00103: Encountered the symbol "end-of-file" when expecting
[code]...
I don't understand some of the errors, such as why line 2 SQL is ignored (it seems correct?), or I'm supposed to properly terminate the trigger (I've read ; and /, but I'm getting the end-of-file errors when I do so). Tried shuffling syntax and ' or " around - and I can't get it.The body SQL works when I replace :NEW.ID with an actual variable (such as 'NMP12'), but I'm not sure how to pass the ID variable from the updated row into the body. The ID is not updated, but other columns are.
How can I reference an Object Type created on a remote database?This is the escenario:
In DATABASE A: CREATE OR REPLACETYPE USERA.EXPO_EXPEDIENTES_RECAUDOS OID 'DCADCB2EA2344DFAB1D205C03D708359' AS OBJECT ( exer_cd_expediente VARCHAR2 (50), exer_id_ident_expediente VARCHAR2 (30), exer_cd_sucursal NUMBER (3), exer_cd_ramo NUMBER (2), exer_nu_poliza NUMBER (7), exer_nu_certificado NUMBER (9), exer_nu_contrato NUMBER (7), exer_cd_nacionalidad VARCHAR2 (1), exer_nu_cedula_rif NUMBER (9), exer_nm_titular VARCHAR2 (70), exer_st_expediente VARCHAR2 (2), exer_de_status_exp VARCHAR2 (240), exer_fe_status_exp DATE, exer_cd_productor NUMBER (5), exer_nm_productor VARCHAR2 (60), exer_cd_mail_productor VARCHAR2 (50), exer_in_habilitado VARCHAR2 (1), exer_in_permite_habilitar VARCHAR2 (1), exer_in_carga_consulta VARCHAR2 (1), exer_cd_ramo_aplicacion VARCHAR2 (200), exer_cd_producto VARCHAR2 (6) )/ In DATABASE B:
After creating the public synonym and asigning the required privileges on the object in DATABASE A, I try to execute the following:
DECLARE x EXPO_ EXPEDIENTES_RECAUDOS;BEGIN null;END;
But i got the following error:
ORA-06550: line 2, column 12:PLS-00331: illegal reference to
USERA. EXPC_ EXPEDIENTES_RECAUDOS@DATABASEA
After investigating a little i found the following, but i dont know how to apply it, "The CREATE TYPE statement has an optional keyword OID, which associates a user-specified object identifier (OID) with the type definition. It should be used by anyone who creates an object type that will be used in more than one database."
(I put ... because there are a lot of columns which are not interesting for this question.)
Remark: team_id and agent_id are neither primary keys nor UNIQUE.
In a third table I have a column with exactly the same data type, that is, VARCHAR2(20). What I need is to make sure that its value is at least in one of the tables TEAM or AGENT (so the only thing that is important is to check that the specified value exists no matter in which of the two tables, but just to make sure that it exists somewhere).
The solution that I have found so far, is to create a BEFORE INSERT trigger on the table. Within the trigger I create a cursor
CURSOR c IS SELECT team_id FROM TEAM UNION SELECT agent_id FROM AGENT;
I have an employee table which has a primary key and a self referencing foreign key, as shown here
create table employee ( id not null, name not null, department not null, supervisor_id not null ,constraint constraint_1 primary key (id) ,constraint constraint_2 foreign key (supervisor_id) references employee (id));
Now if i make the primary key composite, as shown below -
create table employee ( id not null, name not null, department not null, supervisor_id not null ,constraint constraint_1 primary key (id, name) ,constraint constraint_2 foreign key (supervisor_id) references employee (id));
Oracle is throwing the following error -
ORA-02270: no matching unique or primary key for this column-list
How can this error be fixed without changing the composite primary key?
Now I need to start with the employee 1 . As we can see the emp 1 is mapped to dept A and also with multiple dept. Similarly dept id is mapped to multiple emp.
I need the output as below (many to many I.e. cross referencing)
EMPID DEPIDGroup 1A A1 2A A1 2B A1 1B A1 4A A1 5B A1 5A A1 6C B1 -- new group as the emp and dept are not mapped previously 7A A1 8D C1
There is a nested table with in a nested table type and i want to print the value and again assign a new value to the next subscript and i have tried a lot but couldn't find any solution.
declare type type_name is table of varchar2(10); type type_name1 is table of type_name; names type_name1:=type_name1(type_name('hello')); begin -----HOW TO PRINT A VALUE-------- -----HOW TO ASSIGN A NEW VALUE TO NEW SUBSCRIPT null; end;
1) need to print the values of names(1) 2)Assign a value to names(2)
I have to generate a big xml. Each part of the xml needs data from different tables. So I have created two clob to hold the portion of the big xml. How can i have the concatenated clob values as an argument for xml element.
i want to display values of same column with comma seperation like this
SELECT RTRIM(XMLAGG(XMLELEMENT(e,DESCR_INDI || ',')).EXTRACT('//text()'),',') INTO DESCR FROM STUDENT_SKILL_PER WHERE GROUP_NAME=:GROUP_NAME AND SKILL_NAME=:SKILL_NAME AND SUB_SKILL_NAME=:SUB_SKILL_NAME AND TERM=:TERM AND STUDENT_CODE=:STUDENT_CODE AND YEAR_CD=:YEAR_CD;
but the error shown to me that xmlelement must be declared...but when i deploy same query at sql editor it gives me correct result..how i can use it on oracle report 6i... i am using oracle 9i as database.
I have a priority column(possible values are 1 or 0) in a table where
i need to get 70% of high(1) and 30% of low (0) and max i can fetch for select is 50 records.
Eg1: Total if i have 60 in which 20 high and 40 low then 70% of 20 = 14 and remaining should be taken from Low i.e. 36 from low. so total will be 50 transactions.
Eg2: Total if i have 60 in which 40 high and 20 low then 70% of 40 28 + remaining should be taken from Low i.e. 22 from Low.
Eg 3: If i don't have any high then total should be picked from low vise versa.
I have below query but it is having problem when there is no low priority.
SELECT ID,PRI FROM temp tbl WHERE pri = '1' AND ROWNUM < ((70/100)*50)+1 UNION ALL SELECT * FROM temp WHERE pri = '0' AND ROWNUM < 50-(SELECT COUNT(*) FROM temp WHERE pri = '1' AND ROWNUM < ((70/100)*50)+1)
I used a dynamic item_list. This list should contain only the result of the query but I found an empty element in the list. So, how to eliminate this element empty list?
i am trying to update using bulk processing.am facing this ORA-22160: element at index [1] does not exist.
ORA-22160: element at index [string] does not exist
Cause: Collection element at the given index does not exist.
Action: Specify the index of an element which exists.
how to avoid this.
1 create or replace procedure dept_new 2 is 3 type dept_type is table of dept.deptno%type; 4 type tab_type is table of dept%rowtype; 5 --variable declaration 6 dept_t dept_type; 7 tab_t tab_type;

my dept and dept1 tables are both of same structure.
I'm trying to write a generic function for un-nesting child nodes where nesting is deemed unnecessary. Typically when the element only has one child element.
For example, given the following source.... <ROOT> <ITEM> <DESCRIPTION>TEST1</DESCRIPTION> </ITEM> <ITEM> <DESCRIPTION>TEST2</DESCRIPTION> </ITEM> </ROOT>I actually want..... <ROOT> <DESCRIPTION>TEST1</DESCRIPTION> <DESCRIPTION>TEST2</DESCRIPTION> </ROOT>
because we think ITEM isn't really required before we deliver XML data.I've been trying to achieve this with a function, where I pass in the XPath to the node I want flattening, something like
function UnNest(pXMLData XMLType, pXPath varchar2) return XMLType...Called like the following... declare begin vXMLData := UnNest(SomeXMLData, '/ROOT/ITEM') end;I tried using XQuery Update (11gR2), as follows, [code]....
My destination platform is 11gR2 64 bit but going forward I may need a solution for 10gR2 too. Perhaps there is another way without using XQuery Update?
In my pl/sql procedure I'm calling a webservice and it is returning me a varchar2 which contains xml tags.I want to pull values for each element. any one can provide me procedure/function to pull data from it.Below is the output from webservice.
i want to produce a function who return XmlType element if she checks that a parameter (that i passed to here is contained in a row in a defined table)
for example
create table sec_form( form_code VARCHAR2(8) , sec_code VARCHAR2(5) ) ; insert into sec_form values ('CSA','section1'); insert into sec_form values ('CSA','section2'); insert into sec_form values ('CSA','section3');
then i got my function
create or replace function checkIfSectionEnabled (elem XmlType,name_section varchar2) return XmlType is v XmlType; CURSOR myCursor IS select * from sec_form where form_code = 'CSA'; begin open myCursor; loop
[code]....
now i'm gonna call the function (elem XmlType,name_section varchar2) and pass here "section1" for example ; and she must return me my xmltype element if she find "section1" finds section1 present;
when i try t compile i got:
Error(18,13): PL/SQL: Statement ignored Error(18,26): PLS-00225: subprogram or cursor 'MYCURSOR' reference is out of scope
Just installed 4.2.2.00.09 and imported a workspace and an application. Worked fine.I noted a page display difference when compared to the exported application (4.1.0.00.32). I have (so far) found this:If I have a button with Pre Element Text set to <div class="dummy"> and Post Element Text set to </div>, Apex generates an extra div around it all.If my button was named P1_SUBMIT I end up with
I'm studying the guide Oracle XML DB Best practices and it is ok to add, modify or delete nodes. Also to change the value of an attribute, but I'm looking for adding an attribute.What is exactly the statement, for example to add the attribute modification_date for the root element process for a field xml_data ?
I'm trying to get a unique sequential element id for every field in a manual tabular form. Here is the code to generate the form:
SELECT apex_item.hidden(1, lpad(rownum,4,0)) row_num, apex_item.hidden(2, skillset_demand_id) sdi, apex_item.text(3, domain, 20, 20, null, 'f03_#row_num#') Domain, apex_item.text(4, target, 20, 20) Specialization, apex_item.text(5, skill, 20, 20) Skill FROM RI_SKILLSET_DEMAND WHERE WORK_ID = :P511_WORK_IDAccording to the APEX API manual I should be able to set the attribute id with p_item_id*, which in the example of a text item, is the sixth parameter. In line 3 of the code above, I set the p_item_id to 'f03_#row_num#' after having created row_num in line 1.
The HTML I get is: <input id="f03_#row_num#" type="text" value="xxxxxxxxx" maxlength="20" size="20" name="f03"> ... <input id="f03_#row_num#" type="text" value="xxxxxxxxx" maxlength="20" size="20" name="f03">What I want is: <input id="f03_0001" type="text" value="xxxxxxxxx" maxlength="20" size="20" name="f03"> ... <input id="f03_0002" type="text" value="xxxxxxxxx" maxlength="20" size="20" name="f03"> ... etc.
I've tried a lot of things but I can't seem to get parameter substitution inserted into the id attribute so I can get each element uniquely with javascript later.
I would like to update an XML element without using the function APPENDCHILDXML or INSERTCHILDXML because they are not available in Oracle 10GR1. In my database, Oracle XDB is not installed.
The following query fail with the following error : ORA-00904: "INSERTCHILDXML" : identificateur non valide
update scl_profile set profile_data = insertChildXML(profile_data,'/exportImportMarcheCriteria','colonnesExport', XMLType('<colonnesExport>ENTETE_GESTIONNAIRES_AUTORISES</colonnesExport>')) where profile_xmltype = 'fr.mipih.marches.marche.criteres.ExportImportMarcheCriteria' and profile_type = 'eMagh2.MRGS.AccesMarche.ListeMarche.Export.OptionsExportImport'; [code]........
If i try to use the package DBMS_XMLDOM, i have the following error :
ORA-06550: Ligne 3, colonne 11 : PLS-00201: l'identificateur 'DBMS_XMLDOM.DOMDOCUMENT' doit etre declare ORA-06550: Ligne 3, colonne 11 : PL/SQL: Item ignored
I think it's because ORACLE XDB component is not installed in my database.
