SQL & PL/SQL :: Local Variables Are Bind Variables
Apr 27, 2012
Which 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
v1 varchar2(100):=p1;
BEGIN
OPEN p_refcursor FOR select * from Test_tab WHERE item=v1;
END;

I have written a small code while going through the PL/SQL guide but I got a message for the BIND VARIABLE. I don't think I have used any bind variable in this code.
<<outer>>
declare
v_sal1 number(7,2) := 60000;
v_comm number(7,2) : v_sal1 * 0.20;
v_message varchar2(2000) := 'eligible for commission';
begin

Create 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
FUNCTION GET_JOB(
p_jobid IN jobs.job_id%TYPE)
RETURN VARCHAR2
[code]...
This is how I invoked the FUNCTION but WHILE DECLARING THE BIND VARIABLE IT IS GIVING ME AN ERROR!!!!!
VARIABLE b_title VARCHAR2(35)
set serveroutput on
DECLARE
P_JOBID VARCHAR2(10);
v_jobtitle VARCHAR2(200);

I 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).

i 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.

create or replace procedure my_proc(p_user in varchar2) is
l_cursor sys_refcursor;
l_query constant varchar2(1000) :=
'select a'
|| 'from ' || p_user || '.user_table'
|| 'where param0 = :x'
|| 'and param1 = :x'
|| 'and param2 = :x'
[Code]...
Suppose I execute my_proc many times and for multiple values of p_user. For performance reasons, will l_query be stored in the cache as I am using bind variables or it will not since I have the concatenation with p_user value ?

I am trying to create table using bind variable in EXECUTE IMMEDIATE.. I want to know whether oracle allows to create table using bind variable in EXECUTE IMMEDIATE..
Following is the example :
Declare
test_tab varchar2(10) := 'tab_test';
sql_stm varchar2(100);
Begin
sql_stm := 'create table ' || :a || ' (col1 NUMBER)';
dbms_output.put_line(sql_stm);
EXECUTE IMMEDIATE sql_stm
using test_tab;
Exception
WHEN OTHERS THEN
dbms_output.put_line(sqlerrm || ' ' || sqlcode);
End;
After running above block it is giving error : ORA-01008: not all variables bound.

We have recently upgraded application (from Oracle Applications 11.5.9 to 12.1.3) and database (from 9.2.0.5.0 to 11.2.0.3.0).Since we are confronting to performances issues, i try to analyse some queries which Explains plans seems strange (in my opinion).Studying one of them i discover the next case (which according to my logic, i can't explain): --
Just bind variable --select *from MTL_MATERIAL_TRANSACTIONS mmtwhere 1 = 1and mmt.INVENTORY_ITEM_ID = :p1and mmt.ORGANIZATION_ID = :p2and mmt.TRANSACTION_REFERENCE = :p3--and mmt.SUBINVENTORY_CODE = :p4 PlanSELECT STATEMENT ALL_ROWS Cost: 5 Bytes: 361 Cardinality: 1 2 TABLE ACCESS BY INDEX ROWID TABLE INV.MTL_MATERIAL_TRANSACTIONS Cost: 5 Bytes: 361 Cardinality: 1 1 INDEX RANGE SCAN INDEX XXSPE.XXSPE_MTL_MATERIAL_TRANSAC_N99 Cost: 3 Cardinality: 2-- Nvl on bind variable --select *from MTL_MATERIAL_TRANSACTIONS mmtwhere 1 = 1and mmt.INVENTORY_ITEM_ID = :p1and

Am 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....

I executed the following PL/SQL block in SqlDeveloper :
VARIABLE max_dept_no NUMBER
DECLARE
v_dept_name VARCHAR2(30) := '&p_dept_name';
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)"

im as using oracle 8 with sqltools i have a Very large query. and i notice that many things are repeating. so i want to add them to a variable, instead of re-typing them.for example:
select SomeID from SomeTable;
i want SomeID to be put into a variable.but i still want to be able to get a normal select query at the end so that i can see the returned value:
i tried things like:
declare x number;
begin
set x=45454
select x from SomeTable;
end;
but could not get it to work.

consider the trigger below,
CREATE OR REPLACE TRIGGER PPMAPP.PPMCR_HH_CHR_TRG
AFTER UPDATE
ON PPMCR_STEN.PPMCR_HH_CHARACTERISTICS
[code].....
The cursor HH_ATTR_CSR returns a set of values and I'm iterating each values using a loop, but when comparing the post and pre values, I have to use the variable(HH_ATT_VAR) instead of column names.Usually we give it as (re.XXXX_YYYY) but the cloumn names has to be given in the form of a variable got from the cursor like (re.HH_ATT_VAR).In doing so, I'm getting an error as "bad bind variable" So,Is there any to view the old and the new value in the local?

The following code is getting the 'Not all Variables bound' error. There are only two variables so I don't see the order being an issue. Assume the integers are assigned elsewhere.
DateTime beginDT = new DateTime(yearInt, monthInt, dayInt, hourInt, minuteInt, secondInt);
DateTime endDT = new DateTime(yearInt, monthInt+1, dayInt, hourInt, minuteInt, secondInt);
SQL.Append(" WHERE DATE >= :beginDTParameter ");
SQL.Append("AND DATE < :endDTParameter");
OracleCommand cmd = connection.CreateCommand();
cmd.Parameters.Add(new OracleParameter("beginDTParameter", OracleType.DateTime)).Value = beginDT;
cmd.Parameters.Add(new OracleParameter("endDTParameter", OracleType.DateTime)).Value = endDT;

I'm trying to execute a procedure within a Declare/Begin/End statement and using variables as input parameters in my procedure but I keep on getting an Invalid SQL Statement Error. My code is below:
declare
START_dt VARCHAR2(30);
END_DT VARCHAR2(30);
begin
SELECT '01-APR-2011'
INTO END_DT
FROM DUAL;
[code]....
The table the procedure is pulling data from doesn't have proper date/time stamps but my procedure takes the varchar dates above and turns them into dates in the procedure so the input date parameters are left as just string characters.

I was given a SQL query to develop another query that will need to do something similar. The query I was given I believe is a stored procedure. It is PL/SQL and has a SELECT statement that looks like
SELECT :var1 AS var1
FROM t1
WHERE
:var1 = 1
In the past I have seen where variables can be used in the WHERE clause like
SELECT c1
FROM t1
WHERE
c1 = :my_column_valueand this makes sense to me.
Usually :my_column_value is declared in the DECLARE block of the PL/SQL. In the query I was given, :my_column_value is not declared in any DECLARE blocks (maybe I wasn't given the entire code??). But even if it was, that would be even more confusing because in the DECLARE block it could be assigned one value and then set to another value in the WHERE clause???
The first query doesn't make sense to me and when I run it as plain SQL I get an error like "SP2-0552: Bind variable "var1" not declared. I am guessing that such a syntax is not valid for regular SQL?
The only thing I can gather that the first query does is something along the lines of
SELECT 1 as var1
so it will output a 1 for every row. Not always that interesting of a query, but it is needed sometimes, I know. But I still don't understand this type of assignment.
So what's going on here? I'd be happy to look it up and read about it myself, but I don't know what to search for.
