SQL & PL/SQL :: Usage Of Cursors In Stored Procedure
Feb 22, 2012
i have created a stored procedure with a cursor in order to perform a function where the annual_sal from the employee_annual_sal table is refered and checked. The empno for all the records which satisfies the condition mentioned inside the loop should be displayed in an variable. My code is below
create or replace PROCEDURE sp_test_cursor(out_empno OUT number)
IS
v_get_data number;
v_get_empno number;
cursor c1 is
select annual_salary
from employee_annual_sal;
[Code]...
What should i do to return mulitple values in a single variable??
The goal is to create a stored procedure that will retrieve multiple values from a table.
GUI is in Java and they will trigger our procedure to show list of all employees and their roles , doj etc.
So I wrote the following procedure. --------------------------------- create or replace PROCEDURE emp_test( c_cursor OUT SYS_REFCURSOR) AS BEGIN OPEN c_cursor FOR SELECT emp_name, emp_doj, emp_role FROM emp_table ; END; ---------------------------------
I'm using sql developer, stored procedure is compiled and I can manually run it by right clicking on the procedure and click 'Run'.
When I intend to run it by executing the script "Execute Procedure name ", I get errors.
In SQL Developer, I open new SQL file and key in
EXECUTE emp_test;
Highlight it and run the script, here is the list of errors that I get.
------------------------------------------- Error starting at line 18 in command: execute frm_lst Error report: ORA-06550: line 1, column 7: PLS-00306: wrong number or types of arguments in call to 'emp_test' ORA-06550: line 1, column 7: PL/SQL: Statement ignored 06550. 00000 - "line %s, column %s: %s" *Cause: Usually a PL/SQL compilation error. *Action: --------------------------------------------
Issue 2:
Instead of using cursor, is there a way to use multiple parameters and insert the data retrieved from select column_name from table into these parameters and build it in a stored procedure. I tried something like below which did not work. ____________________________________________________
CREATE OR REPLACE PROCEDURE emp_test1 (e_name OUT emp_name%TYPE, e_dob OUT Edob%TYPE) IS BEGIN SELECT emp_nam, Edob INTO e_name, e_dob FROM emp_table END emp_test1; End; ______________________________________________________
Just so you know, there is no input parameter or input feed, when called the procedure should return all the values.
declare v1str varchar2(100):='select empno,ename from emp'; v2str varchar2(100):='select empno,ename,sal from emp'; type t_array is varray(2) of varchar2(100);
[Code]....
So my problem is while executing the different sql statements by passing it to the procedure,how can the procedure would behave dynamically.It must be able to process all the sql statements.
how to print cursors? I mean like columnname : value. of couse curosr.columnname gives what I want. but I want genrally used way.
CREATE OR REPLACE PROCEDURE PROC_TEMP IS BEGIN FOR C1 IN ( SELECT sbjct_id,sbjct_step FROM RND.SBJCT_ORDR M) LOOP DBMS_OUTPUT.PUT_LINE('c1 : '||c1); END LOOP; END;
All these stored procedures deals with insert/updated transactions . i need to create a new stored procedure to execute all this in a single stored procedure which will be something like
create procedure sp4(param1...param8) as begin Execute sp1 param1...param6 rollback if any error Execute sp2 param1...param8 rollback if any error Execute sp3 param1...param4 rollback if any error end;
I have a Table with 4 columns and I am creating a procedure with 4 input parameters and inserting into the table as 4 parameters and how to use loop to insert multiple records.The data to be taken from excel.please suggest how to use the loop to insert multiple records.
create or replace procedure PRC_add_data( P_Emp_No varchar2, P_Member_Name varchar2, P_IDvarchar2, P_UHID varchar2 ) is BEGIN INSERT INTO UploadData (Emp_No,Member_Name,ID,UHID) values (P_Emp_No,P_Member_Name,P_ID,P_UHID) END; /
I would like to use dynamic sql for an select query with where clause and then use the dynamic sql in pl/sql stored procedure. how to create dynamic sql (select query) and how to use it in pl/sql stored procedure.
I entered the following procedure code into SQLPLUS for compilation, but it just hangs. I suspect the cause is an infinite loop, but I can't locate it.
CREATE OR REPLACE PROCEDURE populate_sales_fact AS BEGIN INSERT INTO sales_fact (orderid, prod_key, order_day_key, shipping_day_key, sales_dollar_amount, quantity, cust_key, emp_key) [code]....
I have a sequence my_seq in schema schema1. I have granted select on this sequence to schema2. Doing :
select schema1.my_seq.nextval from dual
in schema2 work as expected. However when I try to compile a package body in schema2 using my_seq in an insert statement, it fails with:
PLS-00302: component 'MY_SEQ' must be declared
What's even stranger is that I have stored procedures that are using the exact same code that are currently compiled and working. Recompiling them yields this error. How is this possible?
Interviewer asked me "Tell me Diff. between Stored procedure vs. Function ".....I given technical answer which is mentioned in my Faq..But he asked me , dont gv me answer in technical manner..He was interested in which case u use Stored procedure and Function....
connect the following concepts/information I've been collecting. This is not my field but I'm interested in filling some of mine conceptual/technical gaps.
From a JDBC perspective, one of the benefits of Prepared (and so Callable) statements have over the regular ones is that the statement is "compiled"(*) once and then reused (performance gain).
(*) for SQL statements: building of parse tree and exec.plan
In which way can this notion be extrapolated to invocation of Oracle Stored Procedures through CallableStatements? (After clearing my doubts, I may end concluding that the only relevant feature of CallableStatements is their capacity to deal with stored procedure invocations)
According to procedure's precompiled execution plan SQL compilation implies execution plans generation PL/SQL compilation implies P-code generation and, SQL statements (from PLSQL code) are treated no differently by Oracle than SQL from Java or C/C++. These SQLs will be parsed and execution plans for those SQLs created. ... When the PL code executes the SQL statement, only then does the SQL engine receive the SQL, parse it, and create an execution plan for it.
Therefore, even when the stored procedure can be parsed and cached in SGA (through the OracleConnection.preparedCall("proc") invocation), the SQL statements won't be effectively compiled until they are executed, right? And going deeper, will those SQL statements be cached to be reused in future invocations of the containing stored procedure? Is this a characteristic of the regular stored procedure execution in Oracle? or is it due to the CallableStatement "origin"?
create or replace PROCEDURE INSERTXML2( p_xml_in XMLType, p_table IN VARCHAR2 ) AS v_context DBMS_XMLStore.ctxType; v_rows NUMBER; BEGIN
[code]....
that works well in little XML files but in XML files that are bigger the stored procedures to not work because string maximum length in Oracle is 4000.
im working with Oracle SQL Developer and Sap Mii, the XML file is generated in Sap Mii and then i have to pass it in one step to database..
I'm trying to create a stored procedure that has two temporary tables within it, and then queries both them tables and inserts the results into a table. I created the script but when they try to run in on the server it wont run.
CREATE OR REPLACE PROCEDURE UpdateFIDB_SP IS BEGIN CREATE GLOBAL TEMPORARY TABLE myAAAA AS (SELECT AAAA.1111, AAAA.2222, BBBB.3333_EXT, CCCC.4444, DDDD.5555, DDDD.6666, DDDD.7777, DDDD.8888, AAAA.9999, EEEE.1010, EEEE.1A1A, EEEE.1B1B, FFFF.3333_LO, FFFF.1C1C, [code]........
I am new to the wonderful world of Oracle. I want to be able to view the results of a stored procedure in an output window, say out of Oracle SQL developer. Unfortunately it appears I need to write some more code to actually view the data. Consider the following:
CREATE OR REPLACE PROCEDURE TESTSPROC2(c_test out sys_refcursor) AS BEGIN open c_test for select * from test_table order by id_no; END TESTSPROC2;
to view this I need something on the order of:
DECLARE cc sys_refcursor; r cc%rowtype; BEGIN TESTSPROC2(C_TEST => cc); loop fetch cc into r; exit when cc%notfound; DBMS_OUTPUT.PUT_LINE('C_TEST = ' || r.data_element); end loop; close cc; END;
But this is weakly typed so I get all sorts of errors associated with the row definition of line 3. create the record based on the table (something like: r test_table%rowtype).
What I really want is a generic reader than can be ported around to output any sproc I put together.
On a more generic note, why Oracle has chosen to make PL/SQL inordinately more complicated than say MS SQL/Servers tSQL? I mean in tSQL I would just write:
CREATE OR REPLACE PROCEDURE TESTSPROC2 AS select * from test_table order by id_no; GO
and viola, a nice result set spits out in Query Analyzer (or a .net application).
After compiling a simple valid SP in Toad for Oracle 8.5.1:
CREATE OR REPLACE PROCEDURE proc_test AS DECLARE v_name VARCHAR2(20) := 'Ed Edson'; BEGIN DBMS_OUTPUT.PUT_LINE('Hi, my name is ' || v_name); END;
The SP is not added to the schema. Also the three status fields (status, created and Last Update in the Procedure Editor remain <Unknown>. It is not a rights or privilege issue, because the creation works perfectly in SQL*Plus!
I have been developing in MS SQL for about 15. So I'm still getting use to the syntax and features within Oracle.I'm trying to create a stored procedure that has two temporary tables within it, and then queries both them tables and inserts the results into a table.I created the script but when they try to run in on the server it wont run.
CREATE OR REPLACE PROCEDURE UpdateFIDB_SP IS BEGIN CREATE GLOBAL TEMPORARY TABLE myAAAA AS (SELECT AAAA.1111, AAAA.2222, BBBB.3333_EXT, CCCC.4444, DDDD.5555, DDDD.6666, DDDD.7777, DDDD.8888, AAAA.9999, EEEE.1010, EEEE.1A1A, EEEE.1B1B, FFFF.3333_LO, FFFF.1C1C, AAAA.1D1D [code].....
There is one DBMSJOB i created schedule to run every day at 22:00 hrs. The jobname is IT_TO_DUM_LOADING and the job type is Stored procedure.
I queried all_source and found stored procedure does not exist in database.
SQL> select text from all_source 2 where type = 'PROCEDURE' 3 and name ='IT_TO_DUM_LOADING';
no rows selected
But i could see the job details in dba_scheduler_jobs view. I cannot use WHERE clause in dba_scheduler_jobs to restrict and find only the job row as i receive time zone error. How it is possible to view the job in dba_scheduler job view whereas i could not find the stored procedure of its in all_source?
