I'm trying to fetch data from Ref Cursor OUT parameter filling by stored procedure. Using latest version of ODP.NET provider (11.2.0.3.0).
My stored procedure:
TYPE cursor_type IS REF CURSOR;
PROCEDURE test_proc (p_recordset out cursor_type) AS
BEGIN
OPEN p_recordset FOR
SELECT 1,2, CURSOR (SELECT 3,4 FROM dual)
FROM dual
END;
END test_proc;
If i'm removing "*CURSOR (SELECT 3,4 FROM dual)*" from the procedure, all works just fine. But when the nested cursor exists in procedure, i'm getting the following exception:
System.NullReferenceException occurred
Message=Object reference not set to an instance of an object.
Source=Oracle.DataAccess
StackTrace:
at Oracle.DataAccess.Client.OracleDataReader.GetOraDbTypeEx(Int32 i)
[code]........
My c# code:
using (OracleConnection conn = new OracleConnection(connString))
*{*
OracleCommand command = new OracleCommand();
command.Connection = conn;
command.CommandType = System.Data.CommandType.StoredProcedure;
command.CommandText = "test_proc";
[code].......
If i'm changing procedure signature from out parameter, to return value, code throws the same exception.
I loop through the 1st cursor (account_csr), while in the 1st csr loop, based on some conditions being true, I want to loop through a 2nd cursor (acctper_csr) but I only want to retrieve data/rows in the 2nd cursor where the account_id column in 1st cursor = account_id column in the 2nd cursor. This will enable me to pull all the account_periods for each account I loop through in the first cursor.
I have attempted several different ways and cannot make this work. Thought I could somehow define a variable and store the account_id from 1st cursor and use on the 'where' clause in the 2nd cursor definition. Have not been able to make this work successfully.
Following is the sample of my
--First cursor (accounts) CURSOR account_csr is SELECT * FROM s_dev_xref1.account A WHERE a.source = 1
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;
declare cursor c is select employee_id from employees; type nst_type is table of employees.employee_id%type; emp nst_type; begin open C; loop exit when C%notfound; fetch c bulk collect into emp; end loop; close c; end;
Above is the sample code, and now i want to pass 'emp' as an input parameter to the procedure.
How can I do that, as emp is of nst_type type and I do not know how my procedure will recognize the datatype...
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 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;

What should i do to return mulitple values in a single variable??
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?
