BIND VARIABLES IN STORED PROCEDURES

I find out that the cause of the decreasing of the Shared_pool in my database is for the sql area.
1* SELECT * FROM V$SGASTAT where name like 'sql%'
SQL> /
POOL NAME BYTES
shared pool sql area 7671024
SQL> R
1* SELECT * FROM V$SGASTAT where name like 'sql%'
POOL NAME BYTES
shared pool sql area 8147424
SQL> R
1* SELECT * FROM V$SGASTAT where name like 'sql%'
POOL NAME BYTES
shared pool sql area 8262016
I flush the shared pool and it increases fastly.
According to my research I have to use bind variables in SQL Statement to avoid this and apart from that modify the init parameter CURSOR_SHARING.
Somebody can help me with a simple example about how to use bind variables in Stored Procedures.
thanks

According to my research I have to use bind variables in SQL Statement to avoid this and apart from that modify the init parameter CURSOR_SHARING.I would not want to change the CURSOR_SHARING. As for use of bind variables in PL/SQL stored procedures, they come in naturally if you use pl/sql variables in your queries:
    l_empno EMP.EMPNO%TYPE ;
    SELECT <columns> INTO <local storage>
    FROM emp
    WHERE
        empno = l_empno ; /* pl/sql automatically binds for you here */
.Please post a small sample of type of queries that you are submitting to the database from within these pl/sql blocks for us to see if there is a possibility of improvements.

Pass BPC SSIS variable to stored procedure

Dear All
We have a ssis package in which there is data flow task. There
is a OLEDB source which uses “Data access mode” as sql command. We used OLEDB data source instead of execute sql task as the outuput is table format generated in Stored proc which is used in following task
This task calls a stored procedure with a input parameter which will be appset name.   [EXEC ProcName '@BPCAPPSET']
The stored procedure is executing fine without any issues.But when I pass variable containing appset name to that stored procedure its not taking properly and package ending successful.
The variable is “BPCAPPSET” it contains appset name which
will be taken front end.
   However to test if this value is taken by stored procedure
or not, I tried to hardcode and pass appset name to stored procedure. i.e exec
ProcName Appset1.
Appset1 is existing appset. It worked fine. But we want to
put this package in all land scapes, such that whenever it is triggered it will
take the appset as parameter and does the calculation in stored procedure.
   Please advice how to pass this variable to stored
procedure.
regards
Prasad

Hi Roberto
Thanks for your mail.
I have tried, but I am getting error that @BPCAPPSET scalar
variable must be defined.
I believe that @BPCAPPSET is system defined variable which
will be passed from Data manager package. May be this is the reason it is not
recognizing this variable?
If so, should I define a variable in SSIS. How can we
assign value of @BPCAPPSET to the newly defined variable?
Please advise. Attached screenshot.

Using Bind Variable in a procedure

Hello all,
Aim - I wanted to set the value of a bind variable in a procedure
I was unsuccessful in doing so, pls help me (pls let me know if u need more info).
I have pasted the commands I executed in a SQL
SQL> VARIABLE x NUMBER;
SQL> EXEC :x := 5;
PL/SQL procedure successfully completed.
SQL> CREATE OR REPLACE PROCEDURE p1
2 IS
3 BEGIN
4 :x := 5;
5 END;
6 /
Warning: Procedure created with compilation errors.
SQL> show err
Errors for PROCEDURE P1:
LINE/COL ERROR
4/5 PLS-00049: bad bind variable 'X'

The reason why the 2nd attempt failed is that in PL/SQL declared code (unlike anonymous blocks) you need to use PL/SQL (host) variables as bind variables and not SQL*Plus (host) variables.
To explain in more detail:
SQL> VARIABLE x NUMBER;
SQL> EXEC :x := 5;
The EXEC creates and transmits the following PL/SQL anonymous block to Oracle:
begin
:x := 5;
end;It also bind the SQL*Plus host variable (defined as X to the bind variable :x).
All well. But not the procedure P1 will not work. Numerous reasons - including that when I call the P1 proc from Delphi, or Joe calls it from Java, or Jack calls it from ASP - we do not have that SQL*Plus host variable X defined. That does not exist in the context when we make our PL/SQL calls to P1.
So how can you write P1 so that we all can use it - from any language?
You provide an input parameter for P1. This allows all of us to bind our host variables to the P1 call. E.g.
create or replace procedure P1( x IN OUT number ) is
begin
x := 5;
end;Now when you call it from SQL*Plus, you would do the following:
SQL> var x number
SQL> exec P1( x=>:X )
When I call it from Delphi, I will bind my Delphi (host) variable to the procedure call. Ditto for Joe and Jack.
Note that PL/SQL itself can also use host and bind variables when talking to the SQL engine. E.g.
create or replace procedure P2( nRows IN OUT number ) is
begin
select count(*) into nRows from all_objects;
end;In this case, nRows in the SQL statement is a SQL bind variable. It is also the PL/SQL host variable. As you can see, this is very similar to what SQL*Plus did with its host variable.
Bind variables (within PL/SQL) is explained in more detail in the Oracle® Database PL/SQL User's Guide and Reference guide.

How to use bind variables in this procedure

Hi Experts,
How to use bind variables in this procedure for static queries.
PROCEDURE DELETE_MER_PROC (M_id IN NUMBER)
IS
BEGIN
V_date DATE;
SELECT PD_DATE INTO v_date FROM PD_MAINTAIN;
    DELETE FROM MER_CLEAR
    WHERE MER_DT < v_date
    AND ID = M_ID;
COMMIT;
END;
How to use v_date and m_id as bind variables in this procedure to avoid hard parsing.
Please help me.
Thanks.

You cannot avoid hard parsing - as the 1st time a SQL statement (like the SELECT or DELETE statements in your code) is encountered, it does not reside in the server's Shared Pool, and needs to be added into the pool via a hard parse.
Bind variables does not prevent hard parsing. Hard parsing happens when the SQL statement (with or without bind variables) is a brand new statement encountered by the server.
Bind variables enables the same SQL cursor to be reused, by simply changing the bind variable value.
Not using bind variables means that each SQL statement is unique and not shareable - as the value is hardcoded into the statement and cannot be changed via a bind value. This typically means LOTS of different SQL statements (where the only difference is the changed value in the statement) are created - with each statement being a new statement not seen before in the Shared Pool and needing to be hard parsed.
One does not design one's code not to be hard parsed. There ALWAYS will be a hard parse in order to get a SQL statement into the Shared Pool. One designs one's code to REUSE cursors in the Shared Pool.

Call Data in Variable in Stored Procedure for Partition Name

Hi,
Here is an excerpt from a Srored Proc I have written.
The aim here is to copy data from a partition of a table.
I first query the partition-name from the ALL_TAB_PARTITIONS table and store the same in a VARCHAR2 variable named partition_name_low.
I then try to select the data in this partition of the table by using the variable name.
PROCEDURE purging AS
partition_name_low VARCHAR2(25);
BEGIN
--+
-- Query for the Highest Value of the timestamp in the 1st partition in current table.
--+
SELECT PARTITION_NAME
INTO partition_name_low
FROM ALL_TAB_PARTITIONS
WHERE TABLE_NAME = 'TABLE1' AND PARTITION_POSITION IN
+(+
SELECT MIN(PARTITION_POSITION)
FROM ALL_TAB_PARTITIONS
WHERE TABLE_NAME = 'TABLE1'
+);+
COMMIT;
COMMIT;
DBMS_OUTPUT.PUT_LINE(partition_name_low ||' ********** ' || TO_char(sysdate, 'MM/DD/YYYY HH24:MI:SS')||' Starting Purging Data *********');
--+
-- Copy data from 1st partition to Archive Table
--+
INSERT /* APPEND */ INTO TABLE1_ARCHIVE+
SELECT * FROM TABLE1 PARTITION(partition_name_low);
However, I am facing an issue here since I keep on gettin an error that "ORA-02149: Specified Partition does not exist".
What I understand is that the Oracle query is picking up the literal string "partition_name_low", instead of the data inside it.
I tried with
&partition_name_low
AND
:partition_name_low
with no luck.
For the 2nd case I get the obvious exception "bad bind variable".
Can someone please suggest in which way I can handle this situation where I can use a variable refer the partition name in a select query?
Thanks in advance!!
Abhishek.

Hi,
You have to use "execute immediate" to launch dynamic SQL command.
So you should write
execute immediate 'INSERT /* APPEND */ INTO TABLE1_ARCHIVE+
SELECT * FROM TABLE1 PARTITION('||partition_name_low||')' ;

Using &variable in stored procedure

Substitution variables in stored procedures

Help, anybody! I want to create a procedure that updates a column of a table, however I want that column and the new data specified at run time. I've tried writing a procedure that has substitution variables for the column and new_data values:
CREATE OR REPLACE PROCEDURE update_client(v_account_id IN VARCHAR2)
IS
v_column varchar2(50);
v_new_data varchar2(50);
last_name varchar2(20);
BEGIN
v_column:=&v_column;
if v_column=last_name then
UPDATE Client set last_name='&v_new_data' where account_id=v_account_id;
end if;
end;
but that's not working, and I also tried to pass v_column and v_new_data as parameters but that won't work either.
CREATE OR REPLACE PROCEDURE update_client (v_account_id IN VARCHAR2, v_column IN VARCHAR2, v_new_data IN VARCHAR2) AS
BEGIN
UPDATE client set v_column=v_new_data where v_account_id=account_id;
END;
I get the error: unable to resolve "V_COLUMN" as a column
Is there anyway at all to do this via a stored procedure? I'm all out of ideas.
Thanks

In Oracle8i you can use dinamic nebeded SQL. In previous versions you need DBMS_SQL.

Variables in stored procedures

Please help me I am trying to get some coding standards set up in the shop that I work in for the DBA group. The problem is that they feel that it is not important to put a prefix or a suffix to variable in a stored procedure.
What is important to me is having either a prefix or a suffix for variables that are passed in, out, and ones that are local to the stored procedure.
They do not feel it will be beneficial and want me to prove the importance. How I would like to prove this is by having as many people reply to this post as possible.
Please let me know what you think. The more replies I get the better the case that I can make to the other people in the group.
Thank you,

I support you, Mr.().It is very important to have a well defined convention, if you want to escape from all those abuses while modifying the script.
<BLOCKQUOTE><font size="1" face="Verdana, Arial">quote:</font><HR>Originally posted by Marco ([email protected]):
Hello unknown person,
The importance of a prefix (or a suffix) in my opinion is that you van tell by the name of the variable its type and origin (parameter, global, local etc) without the need to search for its definition. I find this usefull when you must change code that somebody else wrote cetainly if you work in an object oriented environment.<HR></BLOCKQUOTE>

User-defined datatypes as IN variables in stored procedures

Hello,
I'm trying to write a stored procedure which will accept a custom data type as an IN variable. Using the information here: http://download.oracle.com/docs/cd/B10501_01/appdev.920/a96624/05_colls.htm I've set up a procedure which looks like this:
CREATE OR REPLACE PROCEDURE EDEPOSIT.merch_acct_proc_method_insert
     arg_ALL_PROC_METHODS          IN proc_array
IS
     TYPE proc_array IS TABLE OF VARCHAR2 INDEX BY VARCHAR2;
BEGIN
     arg_METHOD := arg_ALL_PROC_METHODS.first;
     while (arg_METHOD is not null)
     loop
          --processing code
     end loop;
END;
but I'm running into a problem where it seems that the data type needs to be defined before the parameters block (Error(3,27): PLS-00201: identifier 'PROC_ARRAY' must be declared), but a DECLARE block won't co-exist with the CREATE OR REPLACE command (PLS-00103: Encountered the symbol "CREATE" when expecting one of the following: begin function pragma procedure subtype type <an identifier>).
What am I missing?
Thanks in advance!

Whoever is going to call the procedure will have to create a proc_array first. If proc_array is defined inside the procedure, then it can't be referenced from outside the procedure.
A common way to define types is to do so in a package. Procedures normally belong to pacages anyway. You can define a TYPE and a procedure that uses it in the same package, like this:
CREATE OR REPLACE PACKAGE     merch_acct_pkg
AS
TYPE proc_array IS TABLE OF VARCHAR2 (30) INDEX BY VARCHAR2 (30);
PROCEDURE merch_acct_proc_method_insert
     arg_ALL_PROC_METHODS     IN     proc_array

Pass PL/SQL Record variable to Stored procedure in Java

Can some one please give me a code snippet for passing a Record Type variable returned by Stored Procedure. Following is the scenario.
A record type variable REC_VAR is made of three columns of a table as follows
EmpNo Number, Empname Varchar2(50), Zip_Code Varchar2(5).
I am populating this variable in Java code and passing it to Stored Procedure.
Can I referance Record Type variable in a Oracle package from Java code.
How would I define these variables as per tables column type and pass to SP in a java program.

SQL environment variable into a local variable in stored procedure ?

How do i set a SQL environment variable in a session ? How can i read an SQL environment variable into a local variable declared in my stored procedure ? Does any exceptions occur in the process ?
I need this very urgently, can anyone help ?
thanks
srini

You can use a pipelined table function to return it, which is covered here:
http://blog.mclaughlinsoftware.com/plsql-programming/pipelined-functions-plsql-tables/
Alternatively, you can use a SQL Object type wrapped by a collection of that SQL object type inside a TABLE call. I've blogged on that too, here:
http://blog.mclaughlinsoftware.com/2009/03/23/object-record-collections/
If you need something more, leave a comment on the blog. I'm not here on the forum too frequently. Hope that helped.

Variables in stored procedure

Consider the following DDL:
CREATE OR REPLACE insert_requirement
requirement_name VARCHAR2
AS
INSERT INTO requirements (requirement_name) VALUES(requirement_name)
In SQL Server (TSQL), variable names had a @ prefix. In oracle, is there a prefix? In the above statement, will the value in the insert value list come from the variable or column?

better if you post these type of threads in sql, pl/sql sub-functions.

Procedure and Bind Variable

I'm trying to write a procedure for an exercise I'm working on. I got an error that I needed to use a "Bind Variable," so now I'm trying to pass a bind variable to the procedure. I am supposed to get user input.
CREATE OR REPLACE PROCEDURE insert_glaccount

account_desc_pram general_ledger_accounts.account_description%TYPE
AS
BEGIN

BEGIN
:account_num_var := &account_num;
:account_desc_var := &account_desc;
CALL insert_glaccount(:account_num_var, :account_desc_var);
END;
Now I'm getting an error: "Bind Variable "account_num_var" is NOT DECLARED"
Can someone please explain how I'm messing this up?

I don't know if that helps. Now I have this, but it still doesn't work. It looks like the procedure it's self is working, but not the script where I call the procedure:
CREATE OR REPLACE PROCEDURE insert_glaccount
account_num_pram general_ledger_accounts.account_number%TYPE,
account_desc_pram general_ledger_accounts.account_description%TYPE
AS
BEGIN
INSERT INTO general_ledger_accounts
