Refreshing a variable in a procedure

Hi!
I know such thread has been already posted many times, but I do everything as explained and it still doesn't work.
I have created variable STARTDATE: TEXT, Latest Value and a package with following steps:
1) Declare Variable STARTDATE
2) Refresh Variable STARTDATE
3) Procedure
The procedure uses the variable, but doesn't recognize it.
update Table1 set eof_timestamp_2 = eof_timestamp_1 where eof_timestamp_1 >= to_date('#ODS.STARTDATE','dd.mm.yyyy hh24:mi:ss')
Thanks for help

In Designer I have a Global variable called vTARGET_TABLE and in my package I have it set to 'EIM_EMPLOYEE'.
I have a variable that returns the number of rows of the vTARGET_TABLE, and the code of the variable is explained below:
@ Designer mode:
<Datatype: Numeric - Action Not Persistent>
select nvl(max(count(if_row_batch_num)),0)
from <%=odiRef.getSchemaName("W")%>.#vTARGET_TABLE t
group by t.if_row_batch_num;
When I execute it, in Operator appears:
select nvl(max(count(if_row_batch_num)),0) from SNPW.#GLOBAL.vTARGET_TABLE t
group by t.if_row_batch_num;
Generating this error:
911 : 42000 : java.sql.SQLException: ORA-00911: invalid character
java.sql.SQLException: ORA-00911: invalid character
How can I solve it?
Regards.

How to refresh a variable in a procedure

Can I refresh a variable in a procedure so the variable can be used in a next step in the package?
Thanks

Hi,
Create a package with the variable in refresh mode, create a scenario from it and call it from procedure step.
Does it help you?

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.

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||')' ;

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.

Tis might be a browser feature - the variable values tend to get stored - you could look at implementing DSM ( through portal ) or try making your template stateless and see if the value changes...

How to refresh ODI variables from file

Hi,
I followed the fillowing links to implement the dynamic file parameter passing in to the resource name of a datastore.
part-1. http://odiexperts.com/how-to-refresh-odi-variables-from-file-%E2%80%93-part-1-%E2%80%93-just-one-value
part-2. http://odiexperts.com/how-to-refresh-odi-variables-from-file-%e2%80%93-part-2-%e2%80%93-getting-all-lines-once-at-time
For me first part is working fine where as in second part i made canvas looks like
Vlinevariable(refreshing variable)------------------dyanamicfile(refereshing variable)--------------------- interface.
Interface looks like Flatfile to db ,km's are lkm file------sql and ikm is sql incremental update
Vlinevariable is working fine where i am getting numbers in sequence manner to assign in to code of dynamicfile variable and in dynamicfile is not taking that value in to that code and causing session failed.
The code which i put in a refreshing code of dynamicfile is followed below
select     samplefile1_csv     C1_SAMPLEFILE1_CSV

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.

Refresh input variables in Webtemplate

Dear All,
I have a command button in my webtemplate. when i click on this button it should give me variable selection screen to enter Country code in my input variable. My planning function will be executed for this country. But next time when i click this button its not asking me the variable selection screen.its taking the previous entered value. So i have to run the Webtemplate again to run the planning function for a different input variable.
Please tell me how to refresh the variable values so that i can get the Popup screen everytime i click the command button.
Thanks in advance.

Hi,
I have created one web template with one button group , and selected query having variable and exception as data provider.
For button group i have selected "OPEN_VARIABLE_DIALOG" (which is under All commands->command for webtemplate)as a command type. It is working fine.
Try this.
if it is useful assign points.

Want to refresh my variables value

Hi,
I have created a planning layout. whenever I execute this it will shows same values for variables. Actually I want this should looks as a blank and user will put some value. But whenever I execute this planning layout the variable shows some existing values.
I have try to clear this variable but didn't found the option in Planning area, Level, Layout etc.
Could you please suggest me how can I refresh my variables.
I'll assigned you the full marks.
Regards
Manoj

Hi Mayank,
Thanx for your reply and I had given you the points.
Also like to know We don't have any other option to refresh planning variable other than exit..?
If exit then I have to write a Function module and this function module attach to which function group...? If you could give me this details I'll be very thankful to you.
Regards
Manoj

Refresh a variable from several schemas

Is it possible to refresh a variable with data from multiple schemas?
If not, what are the workarounds? The only one I see (apart from dblinking) is to use two variables, refreshing one before refreshing the other.

hmm..I can think of making the schema as dynamic that is put a variable in place of the schema name in your data server. Same thing for physical schema and take a specific logical schema for this. Now in your package refresh the same variable which will hold the schema name. So in run time this value will be substituted there.
Test it and let me know.

ODI - refresh a variable from a file field

Hi,
Is it possible to refresh directly a ODI variable from value stored in a file ? I find a workaround by loading the file into a temp table, and then make a variable refresh, but this solution is not good for me.
Any other idea ?
Thanks,

How to assign a value to ODI Variable using ODI Procedure

Hi ,
Is it possible to assign a value to a ODI Variable using ODI Procedure ?
If it is possible how we can do that.
BEGIN
IF #Counter=1
Then
#Next_Increment:=#Counter+1;
End if;
END;
In my example I have 2 ODI Variables #counter and #Next_increment.
I am trying to assign VALUE TO A ODI VARIABLE #next_increment from another ODI Variable #counter.
thanks
prasanna

Prasanna,
I have a similar requirement where I need to assign values to ODI variables within a procedure. How do we make use of an ODI package to accomplish this ?
Actually, I have a sequence of ODI steps, and there is a call to a procedure 'LOG ERROR' from every step which gets called in case error occurs in any step. I just need to identify from which step the error came.
Please help.
