Executing pl/sql block

hi,
i created a pl/sql block using ed <filename.sql> and tried to execut it useing @<filena.sql> or run <filename.sql>.for the 2nd command the message i got is "nothing
in buffer to run" and for the 1st comm i got nothing. i dint event get prompt.
i am totally new to oracle. please solve my probs.
thanq

To execute the PL/SQL block make sure that you have a "/" at the end of your PL/SQL block and then an <Return character>. Once you have that then you can type C:\..\..\@filename.sql. If you don't put the "/" and "return character" it in your script then after typing C:\..\..\@filename.sql press enter and then type in "/" and then press enter again.

Execute PL/SQL block with named binds from within java code?

Hi guys,
Is there any good way to execute my PL/SQL code, for example
BEGIN         :x := :x+1; END;
from my Java code? I need nothing complicated, just static code block with named binds.
I have tried the Oracle exetnded JDBC (setXXXbyName methods):
public static void main(String[] args){     try {     Class.forName("oracle.jdbc.driver.OracleConnection");     Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","user","password"); String SQL="begin :x:=:x+1; end;"; OracleCallableStatement stmt; stmt=(OracleCallableStatement)conn.prepareCall(SQL); stmt.setIntAtName("x", 5); stmt.registerOutParameter("x", Types.INTEGER); stmt.execute(); System.out.println(stmt.getInt("x"));     } catch (Exception x) { x.printStackTrace();    }   }
And get the java.sql.SQLException: operation not allowed: Ordinal binding and Named binding cannot be combined!
Then i've tried SQLJ appoach:
public static void main(String[] args){     try {     Class.forName("oracle.jdbc.driver.OracleConnection");     Connection conn=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:xe","user","password");       Oracle.connect(conn);       System.out.println("Connected!");           int x=3;       #sql { BEGIN         :x := :x+1;       END; };           System.out.println("x=" + x);     } catch (Exception x) { x.printStackTrace();    }   }
And x=3 had retuned... Although 4 expected.
Then, I've set parameter sqlj.bind-by-identifier=true
And result is another exception! java.sql.SQLException: Missing IN or OUT parameter at index:: 2
Can you please mark my mistakes/point to correct solution?
Thanks in advance,
Alexey

}Now the only thing I need is to code some kind of preprocessor of SQL block, to prepare the dynamicSQL lair for SQL critter...
Please please please show me something less complicated! :8}

Can't create a sequence within a pl/sql block with execute immediate.

Hi All. I created a user and granted it the 'create sequence' privilege though a role. In a pl/sql block I try to create a sequence using 'execute immediate' but get a 1031-insufficient privileges error. If I grant create sequence directly to the user, the pl/sql block completes successfully. Can anyone explain this behavior? We're running 11.2 Enterprise Editon.
Thanks,
Mark

In a definer's rights stored procedure (the default), you only have access to privileges that have been granted directly, not via a role.
There are two basic reasons for that. First, roles can be enabled or disabled, default and non-default, password-protected, etc. so the set of roles a particular user actually has is session-specific. Oracle needs to know at compile time what privileges the owner of the procedure has. The only way to do that (without deferring the privilege check) is to ignore privileges granted through roles.
Second, since 99% of privilege management DBAs do involves granting and revoking roles, it's helpful that changing role privileges will never cause objects to be marked invalid and recompiled which can have side-effects on applications. DBAs only need to worry about causing problems on those rare cases where they are granting or revoking direct privileges to users.
You can create an invoker's rights stored procedure by adding the clause (AUTHID CURRENT_USER). That defer's the security check to run-time but allows the procedure to see privileges granted through roles in the current session. But that means that the caller of the procedure would need to have the CREATE SEQUENCE privilege through the role, not the owner of the procedure.
And just to make the point, dynamic object creation in PL/SQL is almost always a red flag that there is something problematic in your design. If you are creating sequences dynamically, that means that you'd have to refer to them dynamically throughout your code which means that your inserts would need to use dynamic SQL. That's not a particularly easy or safe way to develop code.

Obtaining a collection as a return from an execute immediate pl/sql block

version 10.2
I need to obtain the collection back from the execute immediate of a pl/sql block:
procedure block(owner varchar2) is
stmt                   long;
objecttab_coll         dbms_stats.objecttab;
begin
stmt := '
   begin
    dbms_stats.gather_schema_stats(''' || owner || '''
     ,options => ''LIST AUTO''
     ,objlist => :objecttab_coll
   end;';
execute immediate stmt returning into objecttab_coll;
-- do more stuff here
end block;I have tried this + a few variations but with no luck. In looking through the docs I do not see an example. can this be done?
Thanks
Ox

I dont find any need for an execute immediate here. This must be just enough.
procedure block(owner varchar2)
is
     objecttab_coll         dbms_stats.objecttab;
begin
     dbms_stats.gather_schema_stats(ownname => owner, options => 'LIST AUTO', objlist => objecttab_coll);

How to re-execute anonymous PL/SQL block in package definition ?

Hi all,
I implemented a package which contains procedures and an anonymous PL/SQL block.
This anonymous PL/SQL block is executed only once when the package is called.
and charge in-memory the content of table to avoid multiple SQL access each
time one procedure is called.
As my application open many sessions to the Oracle database, I would like to try
a solution to signal all sessions to reload the content of table when the content
of table is modified. The solution to stop and to restart the connection is not
acceptable.
Best regards
Sylvain

> .. to avoid multiple SQL access each time one procedure is called.
As I understand your posting, this is the actual technical requirement. You want to force serialisation of PL/SQL code. Correct? (only one session at a time can run the procedure)
This feature typically used to accomplish this in o/s code is called a semaphore. PL/SQL does not specifically support semaphores. However, it supports a range of IPC (Inter Process Communication) methods - from message queues to pipes.
One of these IPC interfaces is DBMS_LOCK - which allows a unique lock to be defined and processes to manage their resource usage/execution/etc via this lock using the DBMS_LOCK API.
I've found this a pretty clean and manageable solution to enforce serialisation. Of course, it is even better not to enforce serialisation. Rather design the code to be thread safe and capable of multi-processing/parallel processing.
Personally, I would not use a table as an IPC mechanism as Oracle already provides better IPC mechanisms for PL/SQL code. As for "signalling sessions to re-load the table" - not possible as Oracle sessions cannot register callbacks to handle events. Oracle sessions are not event driven processes from a PL/SQL (application development) perspective.

Execute a string containing a PL/SQL block

Hi,
I would like to build a string containing a PL/SQL block and execute it dynamically. Is there way to do this.
Note - The reason I want to this is because, based on certain table data dictionary views the declaration section of the PL/SQL block that I am building might vary
I tried to use EXECUTE IMMEDIATE, it didn't work, pls let me know if I am missing something.
DECLARE
v_str VARCHAR2(1000);
BEGIN
v_str := 'BEGIN NULL; END';
EXECUTE IMMEDIATE v_str;
END;
/

Hi,
Just happened to find it. EXECUTE IMMEDIATE can be used, the bug with my code was I didn't have a ; after the END statement. Corrected code is below, thanks for your time
DECLARE
v_str VARCHAR2(1000);
BEGIN
v_str := 'BEGIN NULL; END;';
EXECUTE IMMEDIATE v_str;
END;

Accepting user input and executing a PL/SQL block using it

Hi All,
I am working on a requirement wherein I have to accept values from the user for the various arguments to be supplied to a PL/SQL block and then execute it using these values. For now, I am using the following logic:
PROMPT Enter value for the Category
ACCEPT cCategory CHAR PROMPT 'Category:'
DECLARE
cCategry CHAR(1) := '&cCategory';
BEGIN
DBMS_OUTPUT.PUT_LINE('The value of the Category as entered by you is' || cCategory);
END;
PROMPT Press y if you want to proceed with the current values, or press n if you want to re-enter the values
ACCEPT cChoice CHAR Prompt 'Enter y or n:'
DECLARE
cCategry CHAR(1) := '&cCategory';
sErrorCd VARCHAR2(256);
sErrorDsc VARCHAR2(256);
BEGIN
IF '&cChoice' = 'y'
THEN
DBMS_OUTPUT.PUT_LINE('Starting with the process to execute the stored proc');
--- schema1.package1.sp1(cCategry, sErrorCd, sErrorDsc);
--- DBMS_OUTPUT.PUT_LINE('Error Code :' || sErrorCd);
--- DBMS_OUTPUT.PUT_LINE(' Error Description :' || sErrorDsc);
ELSIF '&cChoice' = 'n'
THEN
Now I want that the proc again start executing in the loop from the 1st line i.e. PROMPT Enter value for the Category. However i see that this is not possible to do that PROMPT statements and accepting user inputs execute only on the SQL prompt and not inside a PL/SQL block.
Is there an alternate method to establish this?
Thanks in advance.

Hi,
You can write a genric procedure to achive the desired output. Pass 'Y' or 'N' in the procedure.
Call that procedure in simple pl/sql block during runtime using substituton operator.
For ex
create or replace procedure p1(category_in in varchar2)
IS
BEGIN
if (category_in='Y')
then
prcdr1()
/** Write your logic here ***/
elsif(category_in='N') then
prcdr2()
/** write your logic here***/
end if;
exception
/***write the exception logic ***/
end p1;
Begin
p1('&cat');
end;Regards,

Executing a PL/SQL block (using Toplink)

I have a scenario where I need to execute some fairly complex PL/SQL blocks. As a tester, I am attempting to execute the following simple block:
declare val NUMBER := 1; begin val := 2; end;
Both wrapping this in an SQLCall, or a DataReadQuery give the following exception. What is the best way to execute a PL/SQL block using Toplink?

Could you try the following:
        Session s = ...
        DataModifyQuery dmq = new DataModifyQuery();
        SQLCall sqlCall = new SQLCall();
        sqlCall.setQueryString(
            "declare\n" +
            " val NUMBER := 1;\n" +
            "begin\n" +
            " val := 2;\n" +
            "end;");
        sqlCall.setQuery(dmq);
        dmq.setCall(sqlCall);
        s.executeQuery(dmq);

Executing ddl statment in pl/sql block

Hi all,
could anyone pls help in method for executing ddl statment in pl/sql block other than 'execute immediate' ?

could anyone pls help in method for executing ddl statment in pl/sql block other than 'execute immediate' ?On newer db versions you have more options:
SQL> desc t
Error: object t does not exist
SQL> exec sys.dbms_prvtaqim.execute_stmt('create table michael.t (a integer)')
PL/SQL procedure successfully completed.
SQL> desc t
TABLE t
Name Null? Type
A NUMBER
SQL> exec sys.dbms_utility.exec_ddl_statement('drop table michael.t')
PL/SQL procedure successfully completed.
SQL> desc t
Error: object t does not exist;)

Is there a way to execute the SQL command in PLSQL block

Hi all
With reference to the above subject do you have any example.
Thanks in advance.

What sort of SQL command do you have in mind? DML can easily be wrapped in PL/SQL blocks. DDL requires the use of dynamic SQL such as EXECUTE IMMEDIATE.

Execute anonymous PL/SQL block via JDBC - OUT parameter not available

I have a simple proc on the database:
CREATE PROCEDURE TEST(X OUT BINARY_INTEGER, Y IN VARCHAR) AS
BEGIN
X := 33;
END; I am trying to invoke it via JDBC using an anonymous PL/SQL block:
        try {
            Connection connection =
              DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:ORCL",
                "scott", "tiger");
            CallableStatement stproc_stmt = connection.prepareCall(
                "DECLARE\n" +
                " X_TARGET BINARY_INTEGER;\n" +
                " Y_TARGET VARCHAR(20) := :2;\n" +
                "BEGIN\n" +
                " TEST(X=>X_TARGET, Y=>Y_TARGET);\n" +
                " :1 := X_TARGET;\n" +
                "END;"
            stproc_stmt.registerOutParameter(1, Types.NUMERIC);
            stproc_stmt.setString(2, "test");
            stproc_stmt.executeUpdate();
            Object o = stproc_stmt.getObject(1);
        catch (Exception e) {
            e.printStackTrace();
        } No exceptions are thrown, but the Object o does not get the value '33' - it is NULL.
Any ideas?
thanks in advance,
Mike Norman

I think the issue may be in how JDBC parameter binding is being managed throughout the block's lifecycle.
The slightly-different TEST2 works:
CREATE PROCEDURE TEST2(Y IN VARCHAR, X OUT BINARY_INTEGER) AS
BEGIN
X := 33;
END;
try {
    Connection connection =
      DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:ORCL",
     "scott", "tiger");
    CallableStatement stproc_stmt = connection.prepareCall(
     "DECLARE\n" +
     " Y_TARGET VARCHAR(20) := :1;\n" +
     " X_TARGET BINARY_INTEGER;\n" +
     "BEGIN\n" +
     " TEST2(Y=>Y_TARGET, X=>X_TARGET);\n" +
     " :2 := X_TARGET;\n" +
     "END;"
    stproc_stmt.setString(1, "test");
    stproc_stmt.registerOutParameter(2, Types.NUMERIC);
    stproc_stmt.executeUpdate();
    Object o = stproc_stmt.getObject(1);
catch (Exception e) {
    e.printStackTrace();
}The order of the bind indices ':1' and ':2' are reversed in the above anonymous block - we are returning via ':2'.
I am wondering if 'under the covers' there isn't perhaps a cursor issue. When the original block is parsed and the first bind index is found to be position 2, somehow we can't go back to position 1 - a forwards-only cursor?
