Select after anonymous blocks no INTO allowed
hi
I need to run an EXECUTE IMMEDIATE command to create a SEQUENCE in oracle sql 10g. I can only call EXECUTE IMMEDIATE between a BEGIN and a END; thus creating
an anonymous block
after the EXECUTE I need to do a select
the problem is I get an error no matter what I have after the END;
I cannot put the SELECT in the anonymous block because then I need to use INTO and I don't want to use INTO I just have to da a select
can this be done in any way in oracle 10g(I am using the web interface) ?
this is very frustrating for me as in mysql and ms sql this is sooooo simple and in oracle it looks impossible
thank you in advance

so this cannot be done with oracle?
the selects will return multiple rows what should I do with those rows
I want them to appear on the screen when I run the script with the web interfaceSo you do want to actually capture the data and do something with it.
If you are just running an SQL script through something like SQL*Plus you can just select the data and it will appear on the screen, but if you are doing it within PL/SQL code then you have to capture that data and output it via the appropriate means. Remember that PL/SQL is a process that is running on the database server so it doesn't have an interface to display data on for the user.
You could select the data into an array structure (bulk collect), or use a select loop and then output it using something like DBMS_OUTPUT.PUT_LINE, assuming that your interface is going to read the DBMS_OUTPUT buffer and display the data.
You haven't provided enough information about what you are really doing or the environment you are trying to run it through, for us to be able to give much more advice.
As for whether it can be done with Oracle... yes it can, if you understand the concepts correctly. You can't just select data within PL/SQL and expect it to be displayed on your screen; as I said, the PL/SQL process on the database server knows nothing about your screen.

Anonymous Block with Variable and SELECT
Hi Guys,
I am struggling to connect the material I am learning. I read about anonymous blocks and variables so I want to write a
nice and neat select with all the fancy stuff (variables, exceptions) to get it right and to it as I read in the book.
DECLARE
MYSTRING VARCHAR(10);
MYSTIRNG := 'X';
BEGIN
SELECT * FROM DUAL WHERE DUMMY = MYSTRING
END;
but....this causes one error after the other. Am I getting the concept wrong here or is it a syntax error?cant I just get the result without using variable to store the result in the first place???Perhaps you're better off using a REF CURSOR (a.k.a. cursor variable).
That way you'll pass a resultset to the caller and you don't need any variables to select into.
You can read about them here:

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.

Can select resource content in anonymous block, but not in stored procedure
I know the problem relates to the ACLs but am curious about the following behaviour:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Prod
PL/SQL Release 10.2.0.1.0 - Production
CORE 10.2.0.1.0 Production
TNS for 32-bit Windows: Version 10.2.0.1.0 - Production
NLSRTL Version 10.2.0.1.0 - Production
running on Windows XP sp2
Trying to access an existing resource '/home/test/test.dtd'
/home is owned by SYS
/home/test is owned by me
/home/test.test.dtd is owned by me
The following SQL and anonymous block retrieve the content of the resource:
select extract(p.res,'/*').getClobVal()
from resource_view p
where p.any_path = '/home/test/test.dtd'
declare
alldata clob;
begin
select extract(p.res,'/*').getClobVal()
into alldata
from resource_view p
where p.any_path = '/home/test/test.dtd'
dbms_output.put_line(substr(alldata, 1, 255));
end;
BUT when I encapsulate the anonymous block in a stored procedure, I am told that the folder '/home/test/' does not exist.
As said, the problem related to the ACL on the folders, what I cannot understand, and caused me considerable confusion, is why I was unable to get the content from a stored procedure when I was able to do so from an anonymous block.
regards
RichardUse equals_path(res,'/home/test/test.dtd') = 1OK, OK, but how do you use wildcards (if you want to) since any_path like '/home/test%' works?
Who was the stored procedure owned by. Was it a stand-alone stored procedure or a
method on a package. If it was a method on a package is it AUTHID creator or AUTHID
definer.Everything apart from the '/home' folder is owned by the current user.
The PL/SQL was in a packaged procedure, a stand-alone stored procedure, and an anonymous block. It exhibited the same behaviour in each. All were defined with default AUTHID which is definers rights which is the same as the current user in this case. -

Could you please hint me why the output differs in anonymous blockBecause you've made the mistake of having the same name for your column and your variable.
department_id is taken to be the column on both sides of the equality in your query - so it's picking up all rows. -
I can't seem to get rid of OR use Adobe Reader after I let it into Safari 7. How do I get to the point where Reader is not my preferred anything, but can still be used if Preview won't open something?
Back up all data before making any changes. Please take each of the following steps until the problem is resolved.
Step 1
If Adobe Reader or Acrobat is installed, and the problem is just that you can't print or save PDF's displayed in Safari, you may be able to do so by moving the cursor to the the bottom edge of the page, somewhere near the middle. A black toolbar should appear under the cursor. Click the printer or disk icon.
Step 2
There should be a setting in its preferences of the Adobe application such as Display PDF in Browser. I don't use those applications myself, so I can't be more precise. Deselect that setting, if it's selected.
Step 3
If you get a message such as ""Adobe Reader blocked for this website," then from the Safari menu bar, select
Safari ▹ Preferences... ▹ Security
and check the box marked
Allow Plug-ins
Then click
Manage Website Settings...
and make any required changes to the security settings for the Adobe PDF plugin.
Step 4
Triple-click anywhere in the line of text below on this page to select it, the copy the selected text to the Clipboard by pressing the key combination command-C:
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens by pressing command-V, then press return.
From the folder that opens, move to the Trash any items that have "Adobe" or “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari.
Step 5
The "Silverlight" web plugin distributed by Microsoft can interfere with PDF display in Safari, so you may need to remove it, if it's present. The same goes for a plugin called "iGetter," and perhaps others—I don't have a complete list. Don't remove Silverlight if you use the "Netflix" video-streaming service.
Step 6
Do as in Step 4 with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari. -
PL anonymous block does everything, but then gets stuck
We have a PL/SQL block that loops through a cursor, and inserts data into another table. We're having a strange issue with it... Every single line of code within it appears to function correctly... It does everything we want it to. The last line on it calls a simple function that writes a record to a table we made, to indicate it has completed. It does that, and we can see the record is inserted successfully.
The problem: even though we can see it did everything, it gets "stuck". If we run it as a anonymous block, the sql plus session will just stay stuck. Same thing if we turn it into a procedure and invoke it. It just stays stuck. Viewing it from OEM... We can see the session as "active", but it doesn't show that it's currently executing anything.
How can we go about figuring out what the problem is?
We've tried it on four databases... All windows platforms.. Three were oracle 10g, one was Oracle 11g. One more interesting note: one of the 10g ones... the problem does not occur... the script finishes fine. But, we don't know what is different about this database from the others.
We also notice the problem doesn't happen if we limit the amount of records... the initial cursor we process, if we limit it using "rownum < 100" or something like that, it will also always finish fine.
This is the script:

How come the item value does not come thru via PL/SQL anonymous block?
Hi,
It's a Form with 3 tables -
1) ClinicianProfileTb (with about 40 columns, insert/update via DML),
2) PeopleTb (with about 7 columns, insert/update via PL/SQL anonymous block) and
3) ClinicianPracticeTb (with about 10 columns, insert/update via PL/SQL anonymous block) for after-submit-processes.
So I have several After-Submit-Processes. For some reason, it appears that PeopleId which is supposed to come thru via the 2nd After-Submit-Process (ie: Insert/Update PeopleTb) does not do the way it's supposed to. And when I press "Create" button at the bottom, I got the following error msg:
ORA-01400: cannot insert NULL into ("TEST_0712"."CLINICIANPRACTICETB"."PEOPLEID")
I tried the "debug" mode (via edit page link), but to no avail. (I'm newbie, trying to learn and deliver at the same time :)).
I uploaded the app to apex.oracle.com, if someone could kindly take a look and let me know what goes wrong, it'd be greatly appreciated.
workspace: test_0712
app: 43408 - TEST
user: demo
pswd: demoPswd
Page#21 -> look at the After-Submit-Processes -> in "Insert/Update PeopleTb" it appears that PeopeId does not come thru; thus it cannot be updated to ClinicianProfileTb.PeopleId (allows null) -> and thus cannot be inserted into ClincianPracticeTb.PeopleId (which does NOT allow null). Basically my logic is that in order to create ANY row in ClinicianPracticeTb, BOTH PracticeId AND PeopleId must be present.
Acutally I should have used the PeopeTb as DML (as the driving table) to enforce that PeopleId must be present in order to insert ClinicianProfileTb and ClinicianPracticeTb, but it'd be lots of codes to write to insert/update in ClinicianProfileTb (40 columns).
In addition, does ApEx consider EVERY SINGLE after-submit-process are in ONE transaction for commit/rollback? It appears that it treats all PL/SQL anonymous blocks are in ONE transaction, while Automatic Row Processing (DML) is commited/rolled back on its own?
Thanks much,
HelenAll blocks that do not commit in one of the ways I detailed (and which do not explicitly commit using a commit statement) are part of the transaction started with > the first DML statement issued in any of the page processes and continuing until a commit is issued.Say, there are the following processes in the After-Submit-Processes:
1. Process1 -> Automatic Row Processing (DML)
2. Process2 -> PL/SQL anonymous block
3. Process3 -> PL/SQL anonymous block
Based on what you describe, in the event that if there is no explicit "commit" issued in any of these processes, then an implicit "commit" will be issued at the end of Process3?
Thanks, Scott.

Refresh pl/sql anonymous block via dynamic action?
Greetings again to the community!
Something I must be misunderstanding.
I want to dynamically (ajax) update a select list depending on a page item. Now when you research for operations like this, you get some examples - but which mostly are older and... contain a lot of coding. So I am wondering if this is to be achieved in a simple way using dynamic action.
I have created a testcase here where the html for a select list ist created in a pl/sql anonymous block like that:
begin
for i in (select EMPNO, ENAME from EMP
where DEPTNO = :P50_DEP_NO or
:P50_DEP_NO is null)
loop
htp.p('<option value="' || i.EMPNO || '">' || i.ENAME || '</option>');
end loop;
end;Region header and footer contain the tags for <select id="selEmps"> ... </select>.
When you press [Btn Update Sel], a dynamic action is triggered, that submits :P50_DEP_NO, then refreshes the region with the pl/sql code, so that, after you have enteres another value in :P50_DEP_NO, the select list then shows the employees of that department. Thats the plan, but
Its not working! Can anyone tell me, what I have overlooked here, please?
Thank you and good night for now,
tobiHi Marko,
thanks for your hint. I have already tought about that, but im not sure if this is the solution of this particular situation, because the list really should be generated html-code for formating reasons with jQuery UI and further processing. But I have not worked so much with cascading LOVs, so I really should look into it further.
If I dont find a solution there, I'll get back here.
Thanks and so long,
tobi -

ERROR at line 1:
ORA-01001: invalid cursor
ORA-06512: at line 6Assignment is to create a package that will hold tax rates by state in a packaged cursor. The package will contain a function that can receive a 2 character state abbr. as an argument and find a match in the cursor and return the tax rate for tha tstate. An anonymous block will test the function with state of NC.
Can anyone assist?You would need to call the function to open the cursor before you try to fetch from the cursor
DECLARE
tax_cur tax_update.gencur;
rec_tax bb_tax%rowtype;
l_some_number number;

EXIT WHEN tax_cur%NOTFOUND;
DBMS_OUTPUT.PUT_LINE(rec_tax.taxrate);
END LOOP;
END;A couple of points, though.
1) Your function returns a NUMBER but that NUMBER will always be NULL. It seems rather unlikely that this is really what you want. It would seem to make more sense for the function to return the cursor rather than returning a superfluous number.
2) Your function requires a `bb_tax.state%type` parameter. But your anonymous block doesn't seem to have any concept of a state so I'm not sure what you want to pass in there.
3) Looking at the code, it seems a bit odd that your cursor returns a single column of data. If a state can have multiple rates, wouldn't you need to select some additional criteria in order to figure out which sort of tax each row represents or to otherwise differentiate different rows? If a state can only have a single tax rate, it makes no sense to open a cursor that is only going to ever return a single row.
4) There is no need to declare your own weak ref cursor type (tax_update.gencur). You can just use the Oracle built-in type SYS_REFCURSOR.

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!

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 ThatteI 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.

Handling loop exception in an anonymous block
hI ,
I have a an anonymous block
declare
cursor
local variables
begin
open cursor
some statements
loop
some statement ;
some othet statement;
select something from sometablein local variable where some field = cursor.value ;
some more statements
end loop
some more statements
exception
when whatever
then whatever
end;
Now my select statement may give a NO_DATA_FOUND error which i want to catch and ignore .
Pls tell me how to do it.So that mean you can have multiple exception blocks
in a pl/sql script ?You can have one exception handler per execution block.
Execution blocks can be nested inside other execution blocks.
Handling the error within one exception handler causes execution to return out to the execution of the parent block.
Raising an error within one exception handler causes the execution to go straight to the exception handler of the parent block.
e.g.
-- execution block 1
BEGIN
-- execution block 2
DECLARE
myvar number;
BEGIN
SELECT mynumber INTO myvar FROM mytable;
EXCEPTION
WHEN NO_DATA_FOUND THEN
NULL; -- handle error and return execution to block 1
WHEN OTHERS THEN
RAISE; -- raise any other errors to block 1 exception handler
END; -- block 2
DBMS_OUTPUT.PUT_LINE('Select took place successfully or no data was found');
EXCEPTION
WHEN OTHERS THEN
DBMS_OUTPUT.PUT_LINE('An error occurred either in block1 or in block 2 (except for NO_DATA_FOUND in block2)');
END;
