Pl/sql cursor - issue

Hi all,
can anyone explain how we can do this ....below is the table struct
JAME>select * from addrep;
EMPID ENAME SALARY
ROO1 TEST1 20000
RO02 TEST2 30000
RO03 TEST3 40000
My requ is, after giving the delete stmt on addrep, i need insert all the data which is present at
addrep table to another table called audit_addrep,below is the tab stuct.
JAME>DESC AUDIT_ADDREP
Name Null? Type
COL_NAME VARCHAR2(20)
TAB_NAME VARCHAR2(20)
OLD_VALUE VARCHAR2(20)
NEW_VALUE VARCHAR2(30)
I have written plsql cursor, and i am taking column name from user_tab_cols but i cant properly
insert the data in the audit_addrep....
audit_addrep table should contain data like below :
select * from audit_addrep;
col_name tab_name old_value new_value
empid addrep R001 -
ename addrep test1 -
salary addrep 20000 -
empid addrep R002 -
ename addrep test2 -
salary addrep 30000 -
empid addrep R003 -
ename addrep test3 -
salary addrep 40000 -
Please do needfull thing ...
Regards,
Jame
Note: I cant align properly, i donno how to do that(its not considering the space)

PL/SQL speed issues when using a variable

I have a very strange issue that is causing problems.
I am running Golden connecting to a 11g database.
I created a procedure to insert records into a table based on a query. The source query includes variables that I have populated prior to the insert statement. The problem is that if I use the variable for one very specific where statement, the statement goes from running in less than 1 second, to running in 15 minutes. It gets even more strange though. Not only does a 2nd variable not cause any problems, the exact same variable in the same statement works fine.
This procedure takes 15 minutes to run.
declare
    v_start_period date;
    v_end_period date;
begin
    select add_months(trunc(sysdate,'mm'), -1), trunc(sysdate,'mm')
    into v_start_period, v_end_period
    from dual;
    insert into RESULTS_TABLE
            (first_audit_date, last_audit_date,
            data_column1, data_column2, data_column3)
        select
            a.first_audit_date, a.last_audit_date,
            b.data_column1, b.data_column2, b.data_column3
        from
            SOURCE_TABLE_1 b,
            (select marker_id, min(action_time) as first_audit_date, max(action_time) as last_audit_date
                from SOURCE_TABLE_2
                where action_time >= v_start_period and action_time < v_end_period
                group by marker_id) a
        where b.marker_id = a.marker_id
            and exists (select 1 from SOURCE_TABLE_2
                where marker_id = b.marker_id
                and action_time >= v_start_period and action_time < v_end_period
                and action_type = 'XYZ');
    commit;
end;This procedure runs in less than 1 second, yet returns the exact same results.
declare
    v_start_period date;
    v_end_period date;
begin
    select add_months(trunc(sysdate,'mm'), -1), trunc(sysdate,'mm')
    into v_start_period, v_end_period
    from dual;
    insert into RESULTS_TABLE
            (first_audit_date, last_audit_date,
            data_column1, data_column2, data_column3)
        select
            a.first_audit_date, a.last_audit_date,
            b.data_column1, b.data_column2, b.data_column3
        from
            SOURCE_TABLE_1 b,
            (select marker_id, min(action_time) as first_audit_date, max(action_time) as last_audit_date
                from SOURCE_TABLE_2
                where action_time >= v_start_period and action_time < trunc(sysdate,'mm')
                group by marker_id) a
        where b.marker_id = a.marker_id
            and exists (select 1 from SOURCE_TABLE_2
                where marker_id = b.marker_id
                and action_time >= v_start_period and action_time < v_end_period
                and action_type = 'XYZ');
    commit;
end;The only difference between the two is where I replace the first v_end_period variable with trunc(sysdate,'mm').
I've been googling for possible solutions and keep running into something called "parameter sniffing". It appears to be a SQL Server issue though, as I cannot find solutions for Oracle. I tried nesting the insert statement inside it's own procedure with new variables populated by the old variables, but nothing changed.

Edited by: user_7000017 on Jan 8, 2013 9:52 AM Put the code in code tags.

You are not describing procedures. You are listing anonymous PL/SQL blocks.
As for the code - this approach to assigning PL/SQL variables are highly questionable. As the functions are native PL/SQL functions too, there is no need to parse and execute a SQL cursor, do context switching, in order to assign values to PL/SQL variables.
This is wrong:
select
    add_months(trunc(sysdate,'mm'), -1), trunc(sysdate,'mm')
    into v_start_period, v_end_period
from dual;This is correct:
v_start_period := add_months(trunc(sysdate,'mm'), -1);
v_end_period := trunc(sysdate,'mm');Just as you would not use +"select 1 into plVariable from dual;+", instead of a standard variable assignment statement like +"plVariable := 1;"+.
As for the performance/execution difference. Does not make sense. I suggest simplifying the code in order to isolate the problem. For example, take that in-line SQL (aliased as a in the main SQL) and create a testcase where it uses the function, versus a PL/SQL bind variable with the same data type and value as that returned by the function. Examine and compare the execution plans.
Increase complexity (if no error) and repeat. Until the error is isolated.
The 1st step in any troubleshooting, is IDENTIFYING the problem. Without knowing what the problem is, how can one fix it?

Size of PL\SQL Cursor block

I want to know the internal working of the PL\SQL Cursor. Lets start with a scenario.
     1) I have 3 table with 20 million records each.
     2) I am making a join out of them on a certain condition which gives me 60 million records, now I am putting them in a cursor.
Questions :
     i) Can the Oracle PL\SQL Cursor is capable of holding that much records or there is any limit for it ?
     ii) If there is a limit for such block, then where can I find it and how can I set it ?
     3) If there is no such limit, then running such a query and holding all the data in the Cursor Block would degrade the performance. How Oracle handles such situations, It might be possible that Oracle only have the indexes of those records in the Cursor, but still it would be to time consuming to index 3 different table
Kindly Inform me about this issue ....
Thanks & regards

1. Oracle PL/SQL cursor is just a handle to shared SQL area in Oracle SGA and as such does not consume an awful lot of memory (I would dare to say it consumes peanuts). What is more important it does not depend on number of rows you are going to fetch via cursor
2. Therefore the answer to question 2 is NO
3. Running the query could and would affect you in most unpleasnat ways if you tried to store results of the query in your process memory (PGA/UGA), or more specifically if you created PL/SQL indexed by table and tried to pack all 60000000 rows into it.
If you fetch rows one by one, process the row, throw it away - then no problem... but what do you need to do it for?

At what point is PL/SQL cursor data retrieved?

Hi
This may sound like a silly question but since I am not entirely sure, I thought I'd ask.
In Oracle PL/SQL, do you know at what stage the query in a cursor is actually executed?
Is it at the DECLARE stage or when you first OPEN / LOOP on it?
I suspect upon the OPEN or the LOOP.
I.e. if I had a cursor declared but did not loop (using FOR .. LOOP) through it for some hours, would the query results be as at the time of declare or as at the time of the OPEN / FOR...LOOP?
E.g.
CURSOR invoices
IS
    SELECT invoice_number
    FROM unpaid_invoices
    WHERE due_date < TRUNC (SYSDATE)
BEGIN
-- Some time consuming processing that will take an hour
-- Start Loop through cursor of invoices.
<<overdue_invoices>>
FOR inv IN invoices LOOP
-- Some processing on the invoice
END LOOP overdue_invoices;
END;Would the cursor details for invoices be as at the CURSOR declaration or when the FOR inv... is reached?
Thanks
Martin

When you use a for loop like that it implicitly opens the cursor at the start and closes it at the end of the loop.
But the SQL query in that cursor is actually "run" when the first implicit or explicit fetch is issued, and retrieves new rows for every subsequent fetch.
Of course, before rows can be retrieved there needs to be several other tasks.
There's a good description of the steps of SQL processing in this part of the documentation.
http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10471/adfns_sqlproc.htm
PL/SQL implicitly declares a cursor for all SQL data manipulation statements, including queries that return only one row. For queries that return multiple rows, you can explicitly declare a cursor to process the rows individually.
A cursor is a handle to a specific private SQL area. In other words, a cursor can be thought of as a name for a specific private SQL area. A PL/SQL cursor variable enables the retrieval of multiple rows from a stored subprogram.Edited by: fsitja on Dec 15, 2009 1:03 AM

How to monitor SQL statements issued by SIEBEL ?

Hi,
We have developed BI Siebel 10.1.3.3. application.
One of the requirement is to persist/store in the database real SQL statement issued by BI Dashboards/Answers.
The best solution would be having acces on-line to cursor cache.
Could someone please tell me how to achive this ?

Windows 7 displays error message when exiting +cursor issue

Two issues here. CS5 Phoshop on Wind 7 64 bit.
Physical processor count: 8
Processor speed: 3073 MHz
Built-in memory: 12279 MB
Free memory: 9577 MB
Memory available to Photoshop: 10934 MB
Memory used by Photoshop: 80 %
Image tile size: 128K
First issue is since the latest automatic Adobe update (why fix what isn't broken?) Every time I now exit Photoshop I get the message "Adobe QT Server has stoped working" and occasionally it happens when I exit bridge. Indesign is also behaving badly. I can no longer start a previous document from file manager without ID crashing out.
The other is the cursors in Clone and erase lose their edge (become invisable) for no reason - well not quite. Noise Ninja crashed Photoshop when I tried to use it. I reinstalled it and all is well. The cursor issue seems to be intermittant but came back (for no reason) after I reinstalled NN. I can't seem to change the cursor, no matter what I do. The problem is now seriously affecting how I work. Almost enough to go back to Win XP which ran CS5 Photoshop flawlessly.
Any help will be gratefully accepted.

The recent problem is the entire outline of the cursor (including the crosshair in the middle) was missing at any size of cursor. All I had was exactly what I'd get if I used a real spraygun.
Well, that issue is simply a matter of hitting the Caps Lock key. When Caps Lock is on, you'll see the cursor outline, and when it is off you'll see a crosshair. That's a feature, not a bug.
Glad to hear the 11.1 drivers are out. I will download them and try them now myself.
Regarding "Adobe QT" crashing... QT brings to mind QuickTime, though that is Apple, not Adobe. Do you have Apple QuickTime installed?
Regarding memory usage, with 12 GB of installed RAM, you should be able to set Photoshop to use 90% or more in Edit - Preferences - Performance.

Building report from PL/SQL cursor

Hello,
is there any way to build APEX report using just PL/SQL cursor?
I don't have grant to SELECT from views or tables, but I can use some functions returning row types and cursors. I know I can use them to build table from scratch with htp.p etc., but it’s not very nice. I want to do it using APEX reporting with filtering and pagination functionality.
Is it possible?
Regards,
Przemek

Apologies for the delay, I was out of the office.
Below is a package serving as the basis for creating a view based on a pipelined function. The package is just a skeleton and will not compile in its current form, you will need to go through it filling in the blanks as described by the comments.
If you want some control over what rows are returned by the view from a larger result set, use the set_parameters function in the WHERE clause, E.G.:
select * from really_big_complicated_slow_view where 1 = view_pkg.set_parameters(something_that_reduces_the_view_result_set_size);
Or, a more concrete example:
select result_text from view_to_convert_to_csv where 1 = view_pkg.set_parameters(pi_table => 'my_table', pi_where = 'whatever');
In the spirit of full disclosure, I got the idea for using the "set_parameters" function in the view WHERE clause from a post or blog somewhere a couple of years ago but have lost track of who actually deserves the credit for the good idea.

Implicit PL/SQL cursors remain open, causing ORA-01000 (Client 9.2.0.1)

Hello,
since migrating our system from Oracle Client 9.0.X to 9.2.0.1 (Windows XP), i am encountering troubles when calling a stored procedure from a Cobol-Program:
after a while i run into a 'Maximum open cursors exceeded'-message (ORA-01000)
The stored procedure returns a cursor (ref_cursor)
When Executing the stored procedure, there are actually 2 cursors involved, in fact the stored PL/SQL procedure implicitely opens a child-cursor when doing a select within the PL/SQL.
After fetching the result and closing the cursor in my cobol-program, it correctly closes the cursor associated with the stored-procedure, but it does not close the cursor that was implicitely opened by oracle.
After a while i am running into a Maximum open cursors message, because those cursors have not properly been closed.
Here's a simple PL/SQL package that illustrates the problem:
create or replace package scott.SCOTTS_PACKAGE is
type ref_cursor IS REF CURSOR;
function GET_EMP(EMP_IN CHAR) return ref_cursor;
end SCOTTS_PACKAGE;
create or replace package body scott.SCOTTS_PACKAGE is
-- Function and procedure implementations
function GET_EMP(EMP_IN CHAR) return ref_cursor is
MyCurs ref_cursor;
begin
OPEN MyCurs FOR
SELECT EMPNO ,
ENAME ,
JOB
FROM SCOTT.EMP
WHERE ENAME = EMP_IN;
return(MyCurs);
end;
end SCOTTS_PACKAGE;
Here are some exerpts from my cobol program:
(The program iterates 100x through the section that executes the PL/SQL. After each iteration an additional open cursor remains in the database)

Finally here's an exerpt from V$OPEN_CURSOR, after a few iterations:
1 begin :b1 := SCOTT . SCOTTS_PACKAGE . GET_EMP (:b2 ) ; END ;
2 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
3 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
4 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
5 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
6 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
7 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
8 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
9 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
10 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
11 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
As you see, there is only 1 cursor starting with 'begin ... '
but there are 10 implicit cursors 'SELECT EMPNO, ... ' that have not been properly closed, nor reused by ORACLE.
In our old configuration (ORACLE CLient 9.0.X), you would only see:
1 begin :b1 := SCOTT . SCOTTS_PACKAGE . GET_EMP (:b2 ) ; END ;
2 SELECT EMPNO , ENAME , JOB FROM EMP WHERE ENAME = :B1
meaning all the other cursors have properly been closed.
As a conclusion: the program correctly closes the implicit cursors when using a 9.0 Client, wheras the implicit cursors remain open on Client 9.2.0.1 (Windows XP)
The underlying database can be either 8.i or 9, the problem remains the same.
Finally here's a small Delphi code, using ODAC-components, that somewhat illustrates the same problem:
procedure TForm1.ExecProcClick(Sender: TObject);
var I: INTEGER ;
begin
FOR I := 1 TO 5 DO
BEGIN
SP1.StoredProcName:='SCOTT.SCOTTS_PACKAGE.GET_EMP';
SP1.Prepare;
SP1.ParamByName('EMP_IN').AsString := 'SMITH';
SP1.ExecProc;
SP1.Next;
SP1.Close;
SP1.UnPrepare;
END;
end;
After each call to 'PREPARE', an additional implicit cursor remains open on the database. (using Oracle Client 9.2.0.1)
On our old system (Oracle Client 9.0 or 8.X), the same program would not generate accumulating open cursors on the database
Any suggestions would be welcome,
Claude

Cobol.. been many years since I last even saw some Cobol source code. Invokes all kinds of memories. :-)
Since you found the patch, the advice is superfluous, but works. Close the cursor at the PL/SQL side, e.g.
create or replace procedure CloseRefCursor( cRefCursor TYPELIB.TRefCursor ) is
begin
close cRefCursor;
exception when OTHERS then
-- if the cursor is already gone, not a problem
NULL;
end;In Delphi for example, one can subclass the class used for ref cursor calls and add a call to the above PL/SQL proc in the destructor. Or add create a standard Cobol close ref cursor section that does similar.

Need help on Dynamic SQL Cursor in Forms

Hi All,
I am trying to execute Dynamic SQL Cursor in forms using EXEC_SQL built in.
I have a cursor for example:
'select * from supplier where supplier = '||p_supplier||' and processing_order = '||p_order
My code is
cur_num := Exec_SQL.Open_cursor;
sql_order := 'select * from supplier where supplier = '||p_supplier||' and processing_order = '||p_order;
EXEC_SQL.PARSE(cursor_number, sql_order);
EXEC_SQL.DEFINE_COLUMN(cur_num ,1,ln_Supp_Id);
EXEC_SQL.DEFINE_COLUMN(cur_num ,2,ls_Suppl_Name,30);
EXEC_SQL.DEFINE_COLUMN(cur_num ,24,ls_exchange,20);
sql_count := EXEC_SQL.EXECUTE(cur_num );
While EXEC_SQL.FETCH_ROWS(cur_num ) > 0 Loop
        EXEC_SQL.COLUMN_VALUE(cur_num ,1,ln_Supp_Id);
        EXEC_SQL.COLUMN_VALUE(cur_num ,2,ls_Suppl_Name);
        EXEC_SQL.COLUMN_VALUE(cur_num ,24,ls_exchange);
End Loop;
EXEC_SQL.CLOSE_CURSOR(cur_num );
In this case I have to write 24 Define Columns and 24 Column value. Is there any way to assign them to %rowtype at one time as I need all coulmn of the table.
I had similar case on multiple tables.
Please help me
Thanks,
Maddy

I need this dynamic sql because p_supplier and p_order values changes at run time
I do not understand. Is this a simplified sample or the real thing? You do know that you can pass variables to cursors:
cursor test is
select * from supplier where supplier = p_supplier and processing_order = p_order;
or does e.g. p_supplier hold other parts of the query?
cheers

SQL Performance issue: Using user defined function with group by

Hi Everyone,
im new here and I really could need some help on a weird performance issue. I hope this is the right topic for SQL performance issues.
Well ok, i create a function for converting a date from timezone GMT to a specified timzeone.
CREATE OR REPLACE FUNCTION I3S_REP_1.fnc_user_rep_date_to_local (date_in IN date, tz_name_in IN VARCHAR2) RETURN date

TIME ZONE (tz_name_in) AS DATE),'dd-mm-yyyy hh24:mi:ss'),'dd-mm-yyyy hh24:mi:ss')
INTO date_out
FROM dual;
RETURN date_out;
END fnc_user_rep_date_to_local;The following statement is just an example, the real statement is much more complex. So I select some date values from a table and aggregate a little.
select
stp_end_stamp,
count(*) noi
from step
where
stp_end_stamp
BETWEEN
to_date('23-05-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
AND
to_date('23-07-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')
group by
stp_end_stampThis statement selects ~70000 rows and needs ~ 70ms
If i use the function it selects the same number of rows ;-) and takes ~ 4 sec ...
select
fnc_user_rep_date_to_local(stp_end_stamp,'Europe/Berlin'),
count(*) noi
from step
where
stp_end_stamp
BETWEEN
to_date('23-05-2009 00:00:00','dd-mm-yyyy hh24:mi:ss')

group by
fnc_user_rep_date_to_local(stp_end_stamp,'Europe/Berlin')I understand that the DB has to execute the function for each row.
But if I execute the following statement, it takes only ~90ms ...
select

)The execution plan for all three statements is EXACTLY the same!!!
Usually i would say, that I use the third statement and the world is in order. BUT I'm working on a BI project with a tool called Business Objects and it generates SQL, so my hands are bound and I can't make this tool to generate the SQL as a subselect.
My questions are:
Why is the second statement sooo much slower than the third?
and
Howcan I force the optimizer to do whatever he is doing to make the third statement so fast?
I would really appreciate some help on this really weird issue.
Thanks in advance,
Andi

Hi,
The execution plan for all three statements is EXACTLY the same!!!Not exactly. Plans are the same - true. They uses slightly different approach to call function. See:
drop table t cascade constraints purge;
create table t as select mod(rownum,10) id, cast('x' as char(500)) pad from dual connect by level <= 10000;
exec dbms_stats.gather_table_stats(user, 't');
create or replace function test_fnc(p_int number) return number is
begin
    return trunc(p_int);
end;
explain plan for select id from t group by id;
select * from table(dbms_xplan.display(null,null,'advanced'));
explain plan for select test_fnc(id) from t group by test_fnc(id);
select * from table(dbms_xplan.display(null,null,'advanced'));
explain plan for select test_fnc(id) from (select id from t group by id);
select * from table(dbms_xplan.display(null,null,'advanced'));Output:

Did I miss some thing? And you asked for a sql statement ? How did you come to know that its a sql statement that is causing the error? And if that's actually a sql statement error, isn't it associated with a meaningful message ?
Find the developer who coded the application, he would be the best person to track the error and tell you its resolution IMO.

Need a column based off a PL/SQL cursor, how to do this?

Hi,
I am trying to create a fairly basic report but in the initial data model query, I have one column that is built based off of a PL/SQL cursor. How do I add this into my report? I have tried to create a function under Program Units and reference the function in my select statement for the data model however it keeps saying it is an invalid identifier, and I assume its looking in our database and not the function I created inside the report.
This is what it looks like:
SELECT   a.id,
         b.name,
         F_GET_GENERIC_NAME(b.code) "Generic Name",
         c.strength...and the function i want it to use in my report:
FUNCTION F_GET_GENERIC_NAME (in_code varchar2) RETURN VARCHAR2 IS
BEGIN
DECLARE
generic_name table.column%TYPE;
CURSOR cs_get_generic_name IS
SELECT /*+ USE_HASH (AR) */ desc
FROM a_ref AR, ai_ic AC
WHERE AC.code = in_code
AND   AC.code = AR.code
ORDER BY sort_nbr;
BEGIN
       generic_name := '';
          FOR v_get_generic_name IN cs_get_generic_name
          LOOP
             generic_name := generic_name || RTRIM(v_get_generic_name.desc)
                                 || '/' || ' ';
          END LOOP;
          generic_name := SUBSTR(generic_name, 1,(NVL(LENGTH(generic_name), 0) - 2));
RETURN generic_name;
END;
END;
    Any suggestions? Should I just create the function in the database?

I am trying to do it through a formula column but am encountering the following problem.
I've created a formula column in my data model where I want the column to be (inside the group).
Inside the PL/SQL for the column I reference the function that I had previously created with the following:
function CF_Generic_nameFormula return Char is
begin
     F_GET_GENERIC_NAME(:code);
end;However it won't let me compile, giving the error that "F_GET_GENERIC_NAME is not a procedure or is undefined." Is there something else that I am missing?
EDIT: Nevermind, i missed something simple like putting a return in front of the function call.

How to see pl/sql cursor in v$sql

Hi All,
I am trying to find how many child cursor will be created for select * into employee_rec from employees where employee_id = i however I couldn't find anything?
Do I have to use execute immediate?
Can't I measure PL/SQL cursors?
set serveroutput on;
declare
     employee_rec employees%rowtype;
begin
     for i in 100..110
     loop
            select * into employee_rec from employees where employee_id = i;
            dbms_output.put_line(employee_rec.first_name);
     end loop;
end;
select sql_text, sql_ıd, versıon_count, hash_value from v$sqlarea where sql_text like 'select * into employee_rec from employees where employee_id%';
<<No row returns>>
select sql_text, sql_id, child_number, hash_value, plan_hash_value from v$sql where sql_text like 'select * into employee_rec from employees where employee_id%';
<<No row returns>>
Thanks in advance

For example, I changed the code like the following
I just would like the see the cursor (select * from employees where employee_id = emp_id;) you know what I mean?
set serveroutput on;
declare
cursor my_c(emp_id number) is
select * from employees where employee_id = emp_id;
begin
     for i in 100..110
     loop
            for rec in my_c(i)
            loop
              dbms_output.put_line(rec.first_name);
            end loop;
     end loop;
end;
Thanks

Different cursor issue in CS4 and Window7 x64 Ultimate....

My first post, as I am frustrated and looking for help. I am seeing three ghostly cursors (pointing hands or fists), when I mouse-over some choices in PS4 (11.01, the latest version); like the selections at the bottom of channels or when "transform" is active.
I have built a few PCs and have been doing computers since the early 80's. This is pissing me off! I've tried everything and done a lot of research.
I have Windows7, 64 bit Ultimate, with the latest updates. I have a almost new MSI (Nvidia), 9800 GT graphics card and fancy dual monitors. Photoshop PS4 (version 11.01), and... what else? A PC that was not giving me issues (in Photoshop), till I loaded Windows7!
I tried installing the latest Nvidia driver, 196.21, many times. The last time I saved the files in the nvidia folder in the program files area. The last time it took longer and my screen flashed and it said it was installed (but it always says it is installed), and after that no change in the Windows driver specifications. It still says I have the old Nvidia driver, "8.17.11.9621" What the hell kind of number is that?
I cannot get the 196.21 driver to install. Windows says I have the latest.
Now, I have read about people with partial cursor issues in PS, but nobody with my problem. Such a pisser that you don't know if it is Nvidia, Windows7 or Photoshop.
Lastly, I tried turning off "Enable OpenGL drawing".

The 3 cursor problem could by this advice supplied recently by dec9. "You have your computer Display settings set higher then 100 DPI. Change it to 100 percent or lower." That worked for the other poster.
I have seen posts that stated user had to go in and "scrub" out the old drivers as an update was just not overwriting the old one completely. Not a computer geek so hope this helps.
