I am using oracle text for Arabic language.
I want to save the synonyms list in a database table, so the domain index read from this table, any idea ?
I found a solution :
1- I uploaded my synonyms list to a table called words( contains all the terms and their synonyms' IDs ) and master table called synset (contains synonyms)
2- create thesaurus :
begin
ctx_thes.create_thesaurus ('MyThesaurus');
end;
3- create a stored procedure to read from my table [words] and create relationship between synonyms:
create or replace procedure CreateSynonyms is
CURSOR syn_cur is select s.name_abstract,w.root,w.word_abstract
from p words w , synset s
where w.synset_id=s.synset_id and w.root<>s.name_abstract and w.word_abstract<> s.name_abstract
order by s.synset_id;
syn_rec syn_cur%rowtype;
BEGIN
OPEN syn_cur;
LOOP
FETCH syn_cur into syn_rec;
EXIT WHEN syn_cur%notfound;
begin
ctx_thes.create_relation ('MyThesurus', syn_rec.name_abstract, 'syn', syn_rec.word_abstract);
END LOOP;
END;
4- rewrite my query to select synonyms:
select /*+ FIRST_ROWS(1)*/ sentence_id,score(1) as sc, isn
where contains(PROCESSED_TEXT,'<query>
<textquery>
search for somthing here
<progression>
<seq><rewrite>transform((TOKENS, "{", "}", ","))</rewrite></seq>
<seq><rewrite>transform((TOKENS, "syn(", ",listing)", " , "))</rewrite>/seq>
</progression>
</textquery>
<score datatype="INTEGER" algorithm="COUNT"/></query>',1)>0
Hope this will help someone

Hi i have this simple trigger in oracle
CREATE OR REPLACE TRIGGER OCAP_CREATE_NCRB
BEFORE INSERT
ON OCAP_TBLOCAP
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
DECLARE
Defect_Type varchar2(16);
out_ varchar2(60);
BEGIN
Select A.DEFECT_TYPE into Defect_Type from OCAP_TBLDEFECT A where A.DEFECT_ID = :NEW.DEFECT;
IF Defect_Type = 'C' THEN
--Create NCRB
SP_INSERTTBLD1D2(23,LPAD(:NEW.ISSUED_BY,6,'0'),0,'0','0','035823','Draft',' ',' ',34,' ',0,461,0,0,'035105',trunc(sysdate),' ','A',Lpad(:NEW.ISSUED_BY,6,'0'),Lpad(:NEW.ISSUED_BY,6,'0'),trunc(sysdate),'A',:New.BATCH_NO,out_);
--insert action
SP_INSERTTBLFORMYACTION(Lpad(:NEW.ISSUED_BY,6,'0'), out_, Lpad(:NEW.ISSUED_BY,6,'0'), Lpad(:NEW.ISSUED_BY,'0'), 'Draft');
--Insert other affected Lots
insert into TBLD2LOT(NCRBSERIESNO,LOTNO,CREATEDBY,CREATEDDT,SEQNO) Select (out_), A.BATCH_NO,Lpad(:NEW.ISSUED_BY,6,'0'),sysdate,(TBLD2LOTSEQ.nextval) from OCAP_OTHERBATCH A where A.OCAP_ID = :NEW.OCAP_NO;
--add NCRBSeries no. to table OCAP_TBLOCAP for referencing
Update OCAP_TBLOCAP set NCRBSERIESNO = out_ where OCAP_NO = :NEW.OCAP_NO;
--Insert ocap history
END IF;
END Ocap_Create_NCRB;
/
the first 2 stored procedure is working fine but the insert query is not .
I try to excute the insert query manunaly by replacing the Out_ and the :new.Ocap_no it is working fine.
Is there something wrong in my query?
Hope someone help me out with this.
If it isn't working, then
from OCAP_OTHERBATCH A
where A.OCAP_ID = :NEW.OCAP_NO; --> this condition is never met
which means that no rows in OCAP_OTHERBATCH contain OCAP_ID value which is equal to :NEW.OCAP_NO.
Might be because of wrong letter case, CHAR datatype (right-padded with spaces up to column's full length), ... who knows. Without tables' description and sample data, it is difficult to guess.
I m getting an error as when I compiled the below code as alias required in select list of the cursor.
Create Or Replace PROCEDURE pr_no_debit is
Cursor c_Today(From_date date, To_Date date) is
Select Today from sttm_dates where today between From_Date and To_Date;
cursor c_no_debit is
Select a.* , b.* from STTM_NO_DEBIT_customer a , STTM_FIN_CYCLE b where a.Fin_Cycle = b.Fin_Cycle ;
l_No_Debit_List STTM_NO_DEBIT_CUSTOMER%ROWTYPE;
begin
For i_indx in c_Today(l_No_Debit_List.From_Date,l_No_Debit_List.To_Date)
Loop
for j_indx in c_no_debit
loop
update sttm_cust_account set ac_stat_no_Dr='Y' where account_class=j_index.account_class;
end loop;
End Loop;
-- At the end of the period Change No_Debit to 'N'
End pr_no_debit;
Another solution could be to split the cursor into two parts, though giving alias to respective columns shall be sufficient under the case:
Cursor c_no_debit :
c_no_debit_1: Based on table STTM_NO_DEBIT_customer a
c_no_debit_2: Based on table STTM_FIN_CYCLE b
Through parameterized cursor pass value of of cursor_1 into cursor_2.
Tables STTM_NO_DEBIT_CUSTOMER and STTM_FIN_CYCLE both have a column named FIN_CYCLE, so when the PL/SQL compiler tries to construct the record j_indx from c_no_debit, it gets something like this:
( fin_cycle number
, from_date date
, to_date date
, account_class varchar2(20)
, fin_cycle number
, ...
which is invalid because a record can't have two fields with the same name.
Change c_no_debit to specify only the columns you need, for example:
cursor c_no_debit is
select a.account_class
from sttm_no_debit_customer a
join sttm_fin_cycle b on b.fin_cycle = a.fin_cycle;
(and maybe other columns - I don't have your schema and I don't know what it needs to do)
I am currently using apex 19.1. I have this problem where I can't (or don't know how to) select certain columns from checkbox meaning I have this checkbox
which gives me the ability to check the columns names I want to use that output (:P3_COLUMN) from the check box to select a specific columns in a table. My solution was :
select :P3_COLUMN
from INPUT_TABLE$
I also tried :
select case :P3_COLUMN when 'currency' then currency when 'nationality' then nationality end as test from input_table
which gave me this output
and
DECLARE
str varchar2(100);
BEGIN
str := 'select ' || replace(:P3_COLUMN, ':', ',') || ' from input_table';
execute immediate str;
END;
which gave me this error
I don't know what to do, any help will be really appreciated.
Here's a walkthrough (my page is #51). Suppose that we want to display some column from Scott's DEPT table.
create a region whose type is classic report
create a page item (let's call it P51_COLS which is a select list item; its source is a query which looks like this:
select column_name d,
column_name r
from user_Tab_columns
where table_name = 'DEPT'
Page action on selection should be "Submit page"
region's source should be a PL/SQL function body that returns a SQL query and look like this:
return 'select case when :P51_COLS = ''DEPTNO'' then to_char(deptno )
when :P51_COLS = ''DNAME'' then dname
when :P51_COLS = ''LOC'' then loc
end as result
from dept';
Its "Page items to submit" should be set to P51_COLS
That's it ... run the page; select any column from the select list item and the result should be displayed.
Yes, I know - the query itself looks stupid as you have to name all cases. For some reason, Apex expects literally return 'select ...' statement. Concatenation, replace function, ... won't work. Perhaps someone knows why or - even better - can demonstrate how to workaround it. Meanwhile, try what's been written above.
first option use server side condition on the columns.
second option use dynamic sql> create function returns sql statement> call the function in your region source.
Consider the following three files:
1.csv [contains 3 fields: a, b, c]
2.csv [contains 4 fields: d, e, f, g]
3.csv [contains 2 fields: h, i]
My assignment is to load all three files to their respective table output. So
File "*.csv" ->loads-> Table "*_csv"
I know I can process multiple files with the "Get File Names" step but how do I generate a DDL statement that creates the target table for each file? I am looking at the metadata injection step but I am not sure this fits my needs.
Any advice?

You can below procedure to create the table dynamically.The only prob in this procedure is it is creating table with the same name. play with this code. I created this code in mysql. Prerequisite is you have to pass field names in concatenated form like 'col1,col2,col3'.
delimiter $$
create procedure dynamic_table (col_concat varchar(2000),out query1 varchar(1000))
begin
declare i integer ;
declare v_count int;
declare v_col varchar(100);
set i =1;
select LENGTH(col_concat) - LENGTH(REPLACE(col_concat, ',', ''))+1 into v_count;
set query1 =(select concat('create table table',convert(i,signed),' ( '));
while (i<= v_count)
do
begin
select replace(substring_index(col_concat,',',i),',','_') into v_col;
set query1 = (select concat(query1, v_col,' varchar(1000), '));
set i=i+1;
end;
end while;
select query1;
set query1= replace(query1,substring(query1,length(query1)-1,1),' )');
select query1;
end;$$
sample run : call dynamic_table ('col1,col2,col3',#query1)
I'm trying to build a PL/SQL application to mine frequent item sets out of a set of given data and I've run into a bit of a snag. My PL/SQL skills aren't as good as I'd like them to be, so perhaps one of you can help me understand this a bit better.
So to begin, I'm using the Oracle data mining procedure: *DBMS_FREQUENT_ITEMSET.FI_TRANSACTIONAL*
While reading the documentation, I came across the following example which I have manipulated to query over my data set:
CREATE OR REPLACE TYPE FI_VARCHAR_NT AS TABLE OF NUMBER;
/
CREATE TYPE fi_res AS OBJECT (
itemset FI_VARCHAR_NT,
support NUMBER,
length NUMBER,
total_tranx NUMBER
);
/
CREATE TYPE fi_coll AS TABLE OF fi_res;
/
create or replace
PROCEDURE freq_itemset_test is
cursor freqC is
SELECT itemset
FROM table(
CAST(DBMS_FREQUENT_ITEMSET.FI_TRANSACTIONAL(CURSOR(SELECT sale.customerid, sale.productid FROM Sale INNER JOIN Customer ON customer.customerid = sale.customerid WHERE customer.region = 'Canada' )
,0,2, 2, NULL, NULL) AS fi_coll));
coll_nt FI_VARCHAR_NT;
num_rows int;
num_itms int;
BEGIN
num_rows := 0;
num_itms := 0;
OPEN freqC;
LOOP
FETCH freqC INTO coll_nt;
EXIT WHEN freqC%NOTFOUND;
num_rows := num_rows + 1;
num_itms := num_itms + coll_nt.count;
END LOOP;
DBMS_OUTPUT.PUT_LINE('Rows: ' || num_rows || ' Columns: ' || num_itms);
CLOSE freqC;
END;
My reasoning for using the Oracle FI_TRANSACTIONAL over straight SQL is that I will need to repeat this analysis for multiple dynamic values of K, so why reinvent the wheel? Ultimately, my goal is to reference each individual item sets returned by the procedure and return the set with the highest support based on some query logic. I will be incorporating this block of PL/SQL into another that basically changes the literal in the query from 'Canada' to multiple other regions based on the content of the data.
My question is: How can I actually get a programmatic reference on the data returned by the cursor (freqC)? Obviously I do not need to count the rows and columns, but that was part of the example. I'd like to print out the item sets with DBMS print line after I've found the most occurring item set. When I view this in a debugger, I see that each fetch of the cursor actually returns an item set (in this case, k=2, so two items). But how do I actually touch them programmatically? I'd like to grab the sets themselves as well as fi_res.support.
As always, thanks to everyone for sharing their brilliance!
You are fetching your data into a nested table. So to see the data in there, you would need to loop over the nested table:
FOR i IN coll_nt.FIRST .. coll_nt.LAST
LOOP
dbms_output.put_line(i||': '||coll_nt(i));
END LOOP;
