Anonymous Block Help

Hi all,
DECLARE
TYPE TEST_ARRAY IS TABLE OF EMPLOYEE%ROWTYPE;
V_DATA TEST_ARRAY;
CURSOR C1 IS
SELECT * FROM EMPLOYEE;
BEGIN
OPEN C1 ;
LOOP
FETCH C1 BULK COLLECT INTO V_DATA LIMIT 1000;
FORALL I IN 1..V_DATA.COUNT
NULL;--DBMS_OUT
EXIT WHEN C1%NOTFOUND ;
END LOOP;
CLOSE C1;
END;
Here i how can display the cursor value
Regards,
Fame

You cannot use FORALL for this.. Refer the documentation for FORALL
If you want to try BULK COLLECT you can use like below (for learning purpose), otherwise just loop through the table and print.
declare
    type test_array is table of employee%rowtype;
    v_data test_array;
    cursor c1 is
        select * from employee;
begin
    open c1 ;
    loop
        fetch c1 bulk collect into v_data limit 1000;
            for i in 1..v_data.count loop
                dbms_output.put_line(v_data(i).EMPNO);
            end loop;
        exit when c1%notfound ;
    end loop;
    close c1;
end;

Help for anonymous block

hi friends
I am trying to develop anonymous block which display the message on screen like "hello world" "today is SYSDATE" and "Tommorow is SYSDATE+1".For that i try to develop anonymous block but it shows me error..so friends can you help me out with this...
set SERVEROUTPUT on
declare
p_text varchar2 DEFAULT 'hello world';
P_date date Default sysdate;
P_next_date date default sysdate+1;
begin
DBMS_OUTPUT.PUT_LINE (||P_text);
DBMS_OUTPUT.PUT_LINE ('today is:'||P_date);
DBMS_OUTPUT.PUT_LINE ('Tommorrow is:'||p_next_date);
end;
thanks in advance

Hi, Rommy,
Always format your code. Indent to show the major sections (DECLARE, BEGIN, etc.)
Type these 6 characters
{code}
(small letters only, inside curly brackets) before and after formatted text, to preserve spacing when posting on this site.
DECLARE
     p_text          VARCHAR2 (50) DEFAULT 'hello world';
     P_date          DATE            DEFAULT SYSDATE;
     P_next_date     DATE            DEFAULT SYSDATE + 1;
BEGIN
     DBMS_OUTPUT.PUT_LINE (P_text);
     DBMS_OUTPUT.PUT_LINE ('today is: ' || TO_CHAR (P_date, 'Dy DD-Mon-YYYY'));
     DBMS_OUTPUT.PUT_LINE ('Tommorrow is: ' || TO_CHAR (p_next_date, 'Dy DD-Mon-YYYY'));
END;
/When you declare a VARCHAR2 variable, you have to specify the maximum length.
The || operator is used between two string expressions; it looks like you forgot the first operand in one place.
Using a DATE where a VARCHAR2 is expected (as an operand to ||, for example) is not technically an error, but it's bad practice. Use TO_CHAR to create a string in whatever format you want.

Need help displaying item based on pl/sql anonymous block

This is probably something really simple but I'm stuck.....
On purchase order, I want to show related parent project name and ID. What is the best way to do it? I have created a region based on pl/sql anonymous block, and that works, but the data is above where I want it. I want the project name and ID to show up in the region w/ all the other fields.
I have created an item in the region that has other form fields, item is based on pl/sql anonymous block, w/ same code as above region, and the item doesn't find the data. What's the difference? Is it because the item doesn't save state? In order to choose for the item to be based on pl/sql anon block, APEX made me choose Display as Text (based on PLSQL, does not save state).
Please see this picture:

Getting value with an anonymous block using ODP

Hi all!
I have a problem I hope someone can help me with. I believe it to be a minor one. I am trying to imbed an anonymous block into my .net app and use it dynamically to get a value from the database depending on the values in a tables. Since my procedure is quite large I am displaying a small example proc for simplicity purposes. Basically I want to execute an anonymous block from my app that will return a value (not a row or rows) from the database. The code is below:
Private Sub test()
Dim cn As New OracleConnection(profileString)
Try
Dim sb As New System.Text.StringBuilder
sb.Append("Declare ")
sb.Append("v_maxnum varchar2(6); ")
sb.Append("Begin ")
sb.Append("Select max(to_number(email_address_id)) into ")
sb.Append("v_maxnum from CVWH14_CDRV_TEST.EMAIL_ADDRESS_TBL; ")
sb.Append("dbms_output.put_line(v_maxnum); ")
sb.Append("Exception ")
sb.Append("When Others ")
sb.Append("Then ")
sb.Append("dbms_output.put_line('Program run errors have occurred.'); ")
sb.Append("End; ")
Dim cmd As New OracleCommand(sb.ToString, cn)
With cmd
cmd.CommandType = CommandType.Text
Dim parm As New OracleParameter
parm.ParameterName = "v_maxnum"
parm.OracleType = OracleType.VarChar
parm.Direction = ParameterDirection.Output
parm.Size = 6
cmd.Connection.Open()
Dim ret As Object = cmd.ExecuteScalar()
Dim res As String = cmd.Parameters.Item(0).Value.ToString -- **Error is occuring here**
cmd.Connection.Close()
cmd.Dispose()
End With
Catch ex As Exception
MessageBox.Show(ex.Message, "Error")
'End If
If cn.State = ConnectionState.Open Then
cn.Close()
End If
End Try
End Sub
The exception error reads "Invalid Index 0 for this OracleParameterCollection with Count=0."
If I can figure out how to get a parameter value from the database via the anonymous block, I can apply the logic to the real application. Any help or direction I could receive would be greatly appreciated. Thanks for reading this post!

Thank you for responding. The code that I posted was just one of many ways I have tried. I retried the proc making just 2 changes:
Private Sub test()
Dim cn As New OracleConnection(profileString)
Try
Dim sb As New System.Text.StringBuilder
sb.Append("Declare ")
sb.Append("v_maxnum varchar2(6); ")
sb.Append("Begin ")
sb.Append("Select max(to_number(email_address_id)) into ")
sb.Append("v_maxnum from CVWH14_CDRV_TEST.EMAIL_ADDRESS_TBL; ")
sb.Append("dbms_output.put_line(:v_maxnum); ") -- !Changed this to a bind variable!
sb.Append("Exception ")
sb.Append("When Others ")
sb.Append("Then ")
sb.Append("dbms_output.put_line('Program run errors have occurred.'); ")
sb.Append("End; ")
Dim cmd As New OracleCommand(sb.ToString, cn)
With cmd
cmd.CommandType = CommandType.Text
Dim parm As New OracleParameter
parm.ParameterName = ":v_maxnum" -- !Changed this to a bind variable!
parm.OracleType = OracleType.VarChar
parm.Direction = ParameterDirection.Output
parm.Size = 6
cmd.Connection.Open()
Dim ret As Object = cmd.ExecuteScalar() -- !The error is now occuring here!
Dim res As String = cmd.Parameters.Item(0).Value.ToString
cmd.Connection.Close()
cmd.Dispose()
End With
Catch ex As Exception
MessageBox.Show(ex.Message, "Error")
If cn.State = ConnectionState.Open Then
cn.Close()
End If
End Try
End Sub
I am now getting the error message "Not all variables bound". Any more help or direction that you could throw my way would be greatly appreciated.

Performance problem due to anonymous blocks

Hi,
One of the users on our database has created a procedure consisting of many blocks like the one given below:
begin
select func1(var1,var2,var3)into vcompvalue from dual;
if vcompvalue < 0 then
vcompvalue := 0;
end if;
exception when no_data_found then
vcompvalue := 0;
end;
The procedure takes a long time to execute.Instead of writing a block, will writing SQL%NOTFOUND instead of the exception and merging the blocks with rest of the code improve performance?
Thanks for the help!
Vinayak Thatte

I would guess it might; you'd be cutting down the number of PL/SQL clauses that have to be parsed, etc, so if you have enough anonymous blocks you may see a difference.
On a more specific note can I just ask why you're checking for NO_DATA_FOUND? If DUAL ever throws this exception you've got serious problems with your database. If it's being thrown by your FUNC1 you might be better off (from a performance point of view) handling that exception within the function.

How to use anonymous block in select statement

Hello Experts.
I have one requirement which i can resolve using anonymous block in plsql. But i want implement it in select query only.
Database: Oracle 11.2.0
select count(*) from emp where name='xyz' and sal=50
if count(*)>0
then
select dept,sector from emp where name='xyz' and sal=50
here i dont have any primary key.
How can i achieve above using sql query not plsql. Here is one sloution which i have got but its not satisfying above requiremnt as i dont have any primary key columns
select toll_number from toll_details
where toll_id =(select toll_id from toll_details where toll_new_id='5263655214' group by toll_id having count(*)>0)
here toll_id is primary key, so used group by. But how to do this in my above requirement as i dont have primary key.
Appreciate any help on this.
Thank you

Autonomous Transactions usage in PL/SQL anonymous block coding

Hi,
I am trying to incorporate Autonomous Transaction for our work. I am using the tables provided below,
CREATE TABLE T1
F1 INTEGER,
F2 INTEGER
CREATE TABLE T2
F1 INTEGER,
F2 INTEGER
insert into t1(f1, f2)
values(20, 0)
insert into t2(f1, f2)
values(10, 0)
Now, when I use the code snippet given below, it is working as expected.
create or replace procedure p1 as
PRAGMA AUTONOMOUS_TRANSACTION;
begin
     update t2
     set f2 = 25
     where f1 = 10;
     commit;
end;
declare
PRAGMA AUTONOMOUS_TRANSACTION;
a integer;
begin
     update t1
     set f2 = 15
     where f1 = 20;
     p1();
     rollback;
end;
Here, updation in t2 table is commited and t1 is rolled back, it is working as
expected. I would like to achieve the same functionality through PL/SQL
anonymous block coding, to do this, I use the following code snippet,
declare
PRAGMA AUTONOMOUS_TRANSACTION;
a integer;
begin
     update t1
     set f2 = 15
     where f1 = 20;
     begin
          update t2
          set f2 = 35
          where f1 = 10;
          commit;
     end;
     rollback;
end;
Here, data in both the tables are commited, how do I change it to work as I
mentioned above like committing t2 alone, please help, thank you.
Regards,
Deva

Can you explain what you're trying to accomplish from a business perspective? This doesn't look like a particularly appropriate way to use autonomous transactions, so you may be causing yourself problems down the line.
That said, padders's solution does appear to work for me

Calling a function which has a CLOB parameter via an anonymous block.

OK,
we are moving a lot of exports currently done by Crystal to just be done by stored procs.
So we have a load of existing, some extremely length SQL statements used for these exports.
IN the exports, we have meaningful column headings, so we have a 'lookup' file where all the column names are listed with the desired column name text listed against it.
So - to make our lives easier(i thought) , I have written a Oracle function to extract al;l of the column names as a list (see below).
It works fine except for when I am trying to pass in a SQL treatment that is longer than 4000 character.
What I want to be able to do is simply have an anonymous block that callls my function, I will be running this via SQL explorer.
Something like......
DECLARE
theSQL CLOB;
BEGFIN
theSQL := 'SELECT * FROM ORDERS WHERE 1=0';
SELECT GET_COLUNS_AS_LIST( theSQL, 0 ) FROM DUAL;
END;
However, when I run this I get the error................
PLS-00428: an INTO clause is expected in this SELECT statement
06550. 00000 - "line %s, column %s:\n%s"
*Cause:    Usually a PL/SQL compilation error.
If I hard code the SQL like this, SELECT GET_COLUNS_AS_LIST( 'SELECT * FROM ORDERS WHERE 1=0', 0 ) FROM DUAL; all is well.
Also, I am going to need to be able to pass in SQL ststement longer that 4000 characters as weel so please bear that in mind.
I am not an Oracle guy, so I guess I am missing something fundamental - Please enlighten me with regards to this.
Any help extremely appreciated.
CREATE OR REPLACE FUNCTION GET_COLUNS_AS_LIST( P_SQL IN VARCHAR2, Add_Equals_Sign Number := 0)

Return 'EGG';
END;
--EXAMPLE USAGE

--Select * from SALES_TYPE

So I have ended up with this.
When I next get some time, I'd like to be able to strip out the table and simply output the results to an SQL Developer script window without having to go through the table.
Now this works - but if you see that I am doing something wrong - please point it out.

Anonymous Block in SQL Developer

I am using SQL Developer 3.1x and trying to run a pretty simple Anonymous block and am having trouble declaring a variable. This block runs successfully:
set SERVEROUTPUT on
--declare
-- V_CRT := CHR(13);
begin
for t in (select owner, table_name from dba_tables where owner = 'ABC123)
LOOP
DBMS_STATS.GATHER_TABLE_STATS(t.owner, t.table_name);
end loop;
DBMS_OUTPUT.PUT_LINE('Statistics Calculations complete');
DBMS_OUTPUT.PUT_LINE('Begin Record Counts');
-- DBMS_OUTPUT.PUT_LINE(v_crt);
-- DBMS_OUTPUT.PUT_LINE(V_CRT);
end;
If I remove my comments in an effort to include my Declare statement, I receive: PLS-00103: Encountered the symbol "=" when expecting one of the following
How do I declare / initialize the variable "v_crt"? Admittedly this is a VERY basic Block but I just started to build out a more "robust" procedure and am getting stumped.
Thank you for your help!

The symbol *:=* is for assignment, not variable declaration. Just give the variable name and then its type, like this:DECLARE
V_CRT VARCHAR2(13);You can give it a default value if you want to.DECLARE
V_CRT VARCHAR2(13) := 'Hello';Looks like you want it to be a carriage return character.DECLARE
V_CRT VARCHAR2(1) := CHR(13);

Anonymous Block Troubles

Hey everyone. I'm fairly new to the SQL world and this is my first time posting on any forum for help with coding. I have an assignment and I'm supposed to construct an anonymous block. I am using sqldeveloper and I am trying to run the following:
--declare+
begin
if sysdate between to_date('05:00:00 PM', 'HH:MI:SS PM') and to_date('09:00:00 AM', 'HH:MI:SS AM') then
DBMS_OUTPUT.PUT_LINE ('Can only be used during normal office hours of 9-5.');
end if;
end;
When I run the entire script, there are no errors. However, I can't seem to get any output. Could someone perhaps give me some direction on what I'm doing wrong?
Cheers for any help.
-Aslan

Well that explains a whole lot. Is there some way to actually have it so that sysdate only concerns itself with time?No, in Oracle a DATE type always contains a date and time to the nearest second.
However, you can use to_char and extract what you need:
SQL> select sysdate, to_char(sysdate,'HH24:MI:SS') from dual;
SYSDATE TO_CHAR(
27-MAR-2009 20:42:08 20:42:08
SQL> select sysdate, to_char(sysdate,'HH24') from dual;
SYSDATE TO
27-MAR-2009 20:42:40 20The first one extracts the entire time portion, the second only extracts the hours.

The output is always "anonymous block completed"

Hi ,
I have written a simple Stored Procedure as shown :
create or replace procedure display
ename out emp.ename%type
is
begin
select ename into ename from emp where empno='7369';
end;
I tried to execute the above using this block
declare
ename emp.ename%type;
begin
display(ename);
dbms_output.put_line(ename);
end;
I am always getting the Output as "anonymous block completed" and nothing else .
Please help . Thanks .

if u know that users going to delete the audit table, then take the back of the table. that is better instead of fake update.
U can use exp utility for taking that back up
Pls reply

Customize the Anonymous Block.

Hi All,
DB - Oracle 9.2.0.1.0
With the help of you Guys , I am able to create the Anonymous block.But, In the following BLOCK, I need to add One more functionality, if someone needs to grant "create view" privilge inside the block , then the massage should be " No direct grant allowed, this should be assigned to role. Also, is there any alternate, where we can achieve the same effect without using Associative
DECLARE
v_need_to_assign VARCHAR2(30) := '&ENTER PRIVILEGE ASSIGN';
v_user varchar2(30) := '&USER';
TYPE t_list IS TABLE OF NUMBER INDEX BY VARCHAR2(30);
v_list t_list;
v_chk NUMBER;
e_fail_drop EXCEPTION;
BEGIN
v_list('SYSDBA') := 1;
v_list('CREATE SESSION') := 1;
BEGIN
v_chk := v_list(v_need_to_assign);
RAISE_APPLICATION_ERROR(-20001,'PRIVELEGE '||v_need_to_assign||' is not allowed to be grant');
EXCEPTION
WHEN NO_DATA_FOUND THEN
DBMS_OUTPUT.PUT_LINE('Privilege ' || v_need_to_assign|| ' Granted');
EXECUTE IMMEDIATE 'GRANT '||v_need_to_assign || ' to ' || v_user;
DBMS_OUTPUT.PUT_LINE('THE PRIVELEGE '||v_need_to_assign || ' HAS BEEN GRANTED TO ' || v_user) ;
END;
END;

How to execute a anonymous block

hi all,
I want to execute a anonymous pl/sql block using dbms_sql.
Is it possible to use through dbms_sql. suppose i am having a 100 lines of code in an anonymous block will i be able to execute it through dbms_sql or plz tell me any other way to do it.
note: i will have this anonymous block code in a table. i should take the block from the table and execute it.
Please help me how to do it.
thanks

> we have a table driven approach for our project.
That does not make sense as a table driven approach implies a data driven approach.
Which means that the code is static/fixed and processes the data.
It is very complex to dynamically generate code to perform actions, instead of generating data to tell the code what actions to perform.
This is usually only done in the domains of artificial intelligence and experts systems - and one can debate just how effective that approach is...
Which raises the question as why you would choose such an approach in the first place?
Do you also realise that this dynamic code will likely trash the SQL Shared Pool due to a lack of bind variables? And trashing the Shared Pool that way is the #1 reason for poor performing applications using Oracle?
