SQL & PL/SQL :: Calling Pipelined Function In Merge Statement?
Dec 2, 2010
I am getting a (PL/SQL: ORA-00903: invalid table name) compile error in a procedure using a merge statement. I have seen many examples using this technique and am at a loss as to why I can't compile.
the pipelined function is:
FUNCTION f_crcli_pipe(pi_source_data IN sys_refcursor,
pi_limit_size IN PLS_INTEGER DEFAULT pkg_crcli_variables.c_cursor_limit_def)
RETURN CRCLI_AA
PIPELINED
PARALLEL_ENABLE(PARTITION pi_source_data BY ANY)
IS
[code].....
the error is pointing to the TABLE function in the USING clause of the merge statement.
Orcl Ver: 11g R2. I am leveraging the Oracle's pipelined table function.It's working fine for static SQL.
create or replace package test13_pkg as type r_disc_req is record(disc_line_id number,
req_id number); type t_disc_req is table of r_disc_req; function F_GetDiscReq return t_disc_req pipelined; procedure P_ProcessDiscReq;end; CREATE OR REPLACE PACKAGE BODY test13_pkgAS FUNCTION F_GetDiscReq RETURN t_disc_req PIPELINED IS lo_disc_req r_disc_req; BEGIN FOR r_row IN (SELECT disc_line_id, req_id FROM edms_disc_lines_stg WHERE ROWNUM < 10) LOOP lo_disc_req.disc_line_id := r_row.disc_line_id; lo_disc_req.req_id := r_row.req_id; PIPE ROW (lo_disc_req);
I've used PIPELINED FUNCTION and I've no issues in using this. Just wanted to know is there a way so that I don't need to pipe each row separately and I can pipe a set of rows at once.
Like we use BULK COLLECT INTO to fetch multiple rows at once instead of fetching one row using SELECT INTO.
In the following merge statement in the USINg clause...I am using a select stament of one schema WEDB.But that same select statement should take data from 30 schemeas and then check the condition below condition
ON(source.DNO = target.DNO AND source.BNO=target.BNO);
I thought that using UNIONALL for select statement of the schemas as below.
how to use the MERGE Statement. actually I've used oracle Merge Statement before and it works very well. However today I tried to use and perform a command like that:
Merge into myTable mt using ( select 'data' field1, 'data2' field2, ect from dual union select 'data' field1, 'data2' field2, ect from dual union
[code]...
This has not worked.What am I doing wrong?What could I do to solve this problem and axecute this statement sucessfully?
I have two tables have almost the same columns, how can I use merge statement to update the target table only when there is difference between source and target table. Is there any easier way not compare each column one by one? I am using Oracle 11.2
Here is the MERGE statement:
Merge into tb_trgt trgt using tb_src src on (src.id = trgt.id) when not matched then insert (trgt.id, trgt.nm, trgt.addr) values (src.id, src.nm, src.nm) when matched then update set trgt.nm = src.nm, trgt.addr = src.addr where trgt.nm <> src.nm or trgt.addr <> src.addr ;
Is there any easier way to specify the where clause in the NOT MATCHED? I don't want compare each column of the tables. Since I may have many columns in the tables.
CREATE TABLE TEST11(TNO NUMBER(5), TVAL VARCHAR2(100), TID VARCHAR2(10)); INSERT INTO TEST11 VALUES(1,'VIJAYA','TEST'); INSERT INTO TEST11 VALUES(2,'VIJAYA','TEST'); INSERT INTO TEST11 VALUES(3,'VIJAYA','TEST'); INSERT INTO TEST11 VALUES(4,'VIJAYA',''); INSERT INTO TEST11 VALUES(5,'VIJAYA','');

My requiremen is if record is exists then i wan to update some value, if record not existes the i wan to insert new record
mbr has 60,000 rows and member has 60,000 rows approx. two tables have indexes on ssn, and citi_no on them.
PK of mbr : mbr_id PK of member : mbr_id
other columns are not PK, and have no index on it.
I'm wondering why the statment doesn't use index while ssn and citi_no have index.
MERGE INTO mbr t USING (SELECT mbr_id,citi_no FROM member) a ON (t.ssn = a.citi_no) WHEN MATCHED THEN UPDATE SET t.asis_mbr_id = a.mbr_id where t.ssn not in(select ssn from mbr group by ssn having count(*) > 1)
I am writing below MERGE statement. In this cardinality between table_a and table_b is 1:2. I.e. each record in table_b corresponds to 2 records in table_a based on columns in ON clause.
Well this query throws below error.
----Error---
ORA-12801: error signaled in parallel query server P011
ORA-30926: unable to get a stable set of rows in the source tables
However, the same statement executes successfully when PARALLEL hint is removed altogether. (There are no duplicates in table_b based on unit,group,loc columns.)
-----Query--------
MERGE /*+ PARALLEL(8) */ INTO table_a a USING table_b b ON (a.unit = b.unit AND a.group = b.group AND a.loc = b.loc)
I am planing to write the web-application which use Oracle DB 11g.I would like to understand what are the differences (specially, performance issues, steps of execution, optimizer possibilities) between calling SQL statements and PL/SQL procedures/functions. Which approach is more appropriate, and why?
Examples: a) WebApp->Call("select * from employees where department_id = ?", 10) ;
b) WebApp->Call("? := mypackage.get_emp(?)", refCursor, 10);
create package mypackage is function get_emp(dep_id in number) return sys_refcursor is begin open cur for select * from employees where department_id = dep_id; end; end;========================================== Requirements: High-concurrency, 100+ db sessions, DB will not be used for business-logic.
-- Create a table type of the table you want TYPE tbl_test IS varray(100) of VARCHAR2(30);
-- Function that will return the table type FUNCTION fnc_test RETURN tbl_test;
-- End package END;
CREATE OR REPLACE PACKAGE BODY pkg_test AS FUNCTION fnc_test RETURN tbl_test IS -- type table_name_va is varray(100) of VARCHAR2(30); -- Variable of the type tbl_test
[code]...
But i am having problem calling this to test it.
declare TYPE tbl_test IS varray(100) of VARCHAR2(30); var_tbl_test tbl_test; begin var_tbl_test:= pkg_test.fnc_test;
I created a PROCEDURE in that i am calling function which calculate sum of salary...I just want Output in format for that which function i need to use...?
Actual Output:::
DEPt_Name SALARY ACCOUNTING 8750 RESEARCH 10875 SALES 11600
I want Output in well alignment column...i WANT Output IN column format but my output in not geting in that format...Is there any function to align output...I want Output in well alignment column
For procedures, we need to grant EXECUTE privilege.
For example:
grant execute on scott.process_salary to john;Lets say I have a function SCOTT.GET_EMPIDS and I want another user john to be able to invoke this fuction. So, what is the privilege that needs to be granted to John.
I tried to use external C procedure from the database and i did all required steps as below. 1. create a C program 2. compile and link the C program 3. copy it to the Oracle_home/bin directory 4. configure listener.ora and tnsnames.ora files
I'm trying to execute a dynamic sql that calls a function. But that function has inserts and deletes inside and this way it can't be called through a select statement. And to be worst, it has an other problem, my function uses a record type as parameter.
My code (sample): ----------------- DECLARE type r_parameters is record (cd_query cons_query_param.cd_query%type, cd_usuario cons_query_user.cd_usuario%type, nr_param cons_query_param.nr_param%type, vl_param varchar2(2000),
