Aug 25, 2008I Want to declare some host variables with global scope. Like this C variable:

char str_var[20];

But i can't put SQL sentences in a include file. And if i do this:

...
EXEC SQL BEGIN DECLARE SECTION;
char str_var_h[20];
EXEC SQL END DECLARE SECTION;
...
... I can't see this variable from others sources, although I declare it like 'extern'.

Apr 27, 2012Which of the below is considered a bind variable. In example one proc. Test the parameter p1 is directly used in the query, so this can be considered as a bind variable.
Is that true about the second proc. where p1 is assigned to a local variable v1 , or this needs hard parsing because v1 is not a bind variable ?
Create or replace procedure test(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS
BEGIN
OPEN p_refcursor FOR select * from Test_tab WHERE item=p1;
END;
------------
Create or replace procedure test1(p1 IN VARCHAR2,p_refcursor OUT SYS_REFCURSOR) IS

SQL & PL/SQL :: FUNCTIONS - Bind Variables?
Nov 20, 2012Create and invoke the GET_JOB function to return a job title.
a.Create and compile a function called GET_JOB to return a job title.
b.Create a VARCHAR2 host variable called b_title, allowing a length of 35 characters. Invoke the function with job ID SA_REP to return the value in the host variable, and then print the host variable to view the result.
This is my FUNCTION:
CREATE OR REPLACE

p_jobid IN jobs.job_id%TYPE)
RETURN VARCHAR2

This is how I invoked the FUNCTION but WHILE DECLARING THE BIND VARIABLE IT IS GIVING ME AN ERROR!!!!!

SQL & PL/SQL :: Dynamic Where Clauses And Bind Variables?
Jun 6, 2012I have a requirement where I have to return data as per filter clauses provided on the front end, which may or may not be filled as per the users' choice.
To create a test case, I have created a query joining the emp and dept tables and I add the where clauses dynamically depending on whether the filter has been provided or not.
CREATE OR REPLACE TYPE emp_ot AS OBJECT (
empno NUMBER(4),
ename VARCHAR2(10),
[Code]....
It works very well, the 'literals' are being converted into bind variables (due to CURSOR_SHARING being set to SIMILAR) and the optimizer is able to figure out the correct execution path every time, although it is true that potentially 5 versions of this query will be sitting in the shared pool, but the DBAs are happy to live with that.
Going forward in version 12, CURSOR_SHARING=SIMILAR will be deprecated and the DBAs are not happy for us to write this sort of code anymore.
Is there a suitable way to achieve what this piece of code does?
I have tried and tested this method:
SELECT emp.empno, emp.ename, emp.job, dept.deptno, dept.dname
FROM emp, dept
WHERE emp.deptno = dept.deptno
AND emp.empno = NVL(p_empno, emp.empno)
AND emp.ename LIKE NVL(p_ename, emp.ename)||'%'
...
but the query takes far longer to execute in this manner (that is using my real tables).

PL/SQL :: Bind Variables And Expression Evaluation
Aug 29, 2013i have been looking at a query that uses a wrong plan. db=11.2.0.3 with user bind peeking enabled. this is a simplified version demonstrating the problem:
select egp.bsn,egp.klantnummer as "Persoonsnummer", egp.samengesteldenaam as "Samengesteldenaam", egp.geboortedatum as "Geboortedatum"from pr_eigenschappen2 egpwhere(egp.bsn = :b1 or :b2 is null)and rownum < 51 egp.bsn is varchar2(10) and has high selectivity (almost unique), and is btree-indexed. table and index have adequate statistics. when run with b1:=928818 and b2:=928818 (both bound as varchar2(10)) a full table scan+filter is used on pr_eigenschappen2. if the query is changed to select egp.bsn,egp.klantnummer as "Persoons nummer", egp.samengesteldenaam as "Samengesteldenaam", egp.geboortedatum as "Geboortedatum"from pr_eigenschappen2 egpwhere(egp.bsn = :b1 or 928818 is null)
and rownum < 51the index on bsn is used, and the query is not taking 3.9 seconds but 1 millisecond.if i would have a choice, the query would be different. i don't want to talk about the raison d'etre of the query, i would like to know why the optimizer is not using the index in the first case.

SQL & PL/SQL :: Bind Variables / Developing Stored Procedures In Developer
May 16, 2010Am using Oracle 9i and developing stored procedures in SQL Developer. Have a situation where one stored procedure A is calling another B. Stored proc B builds the SQL based on parameters passed in. For one of the parameters i would like to use a bind variable in the SQL that proc B builds. The bind var is passed back to proc A as a part of the SQL string. In proc A, i then try to bind that variable to a parameter(value), however, the bind does not seeem to work.
The SQL string contained in v_SQLStatement defined as VARCHAR(4000) that is passed back to proc A looks like:
SELECT em.event_title AS event_name,
e.start_date AS start_date,
e.end_date AS end_date
FROM d_event_ml em
inner join d_event e
ON em.event_id = e.event_id
WHERE em.language_id = 46
AND e.end_date >= SYSDATE
AND e.stream_id IN ( :v_x1 )
AND e.event_id IN (SELECT event_id
FROM d_events_seas
[code]....
and o_EventList is defined as REF CURSOR. i'm experiencing is that :v_x1 stays as :v_x1 and does not change.This is my first attempt at using bind vars. URL....
Client Tools :: Providing Bind Variables As Values In Insert Statement?
Aug 23, 2011I executed the following PL/SQL block in SqlDeveloper :

v_max NUMBER(4,0);
BEGIN
SELECT MAX(department_id) INTO v_max FROM departments;
:max_dept_no := v_max + 20;
INSERT INTO departments VALUES (:max_dept_no,v_dept_name, NULL,NULL) ;
END;
/
And it gave the error : Quote:Error report:
ORA-01400: cannot insert NULL into ("HR"."DEPARTMENTS"."DEPARTMENT_ID")
ORA-06512: at line 7
01400. 00000 - "cannot insert NULL into (%s)"

View 2 Replies View RelatedPrecompilers, OCI & OCCI :: Keep Getting ORA-22275 From Extproc?
Sep 26, 2012I am trying to give back data from a stored procedure written in C. I registered the functions as follows:create or replace procedure version(versioninfo OUT clob) as external name "version" library myLib language c with context parameters (context, versioninfo, versioninfo INDICATOR SB4); It compiles fine. The function being called look like this:
extern "C" DLLEXPORT
void version(OCIExtProcContext* context, OCILobLocator **out, sb4 *ind_out){
OCIEnv* envh;
OCISvcCtx* svch;
OCIError* errh;
OCIExtProcGetEnv (context, &envh, &svch, &errh);
std::string versioninfo = "104";
oraub8 maxChar = 10;
[code]...
If I execute the procedure with SQLDeveloper by pressing "play" it is getting executed but there is no result. If I try to execute it from an anonymous block it results in ORA-22275 instead of doing anything.
declare
res clob;
begin
-- the following doesn't work much
--dbms_lob.createtemporary(res,true);
version(res);
dbms_output.put_line(res);
end;
Actually I have to questions:
1.) Why does Oracle give me the error? In my opinion all requirements mentioned by the error description are met.
2.) Why is there no output when executing the function via SQL Developer? Is the usage of OCILobWrite wrong?
