How should I pass complicated sql statements to a function ?

Hello
Some built-in functions, such as dbms_advisor.quicktune accepts sql statements as in parameters. Those parameters are treated as varchar2, but if the sql statement is complicated and contain " ' " characters then its hard to pass those params, Sometimes they arent parsed correctly.
How should I pass a complicated statement (with subqueries, strings and so) to a function ?
Thanks
Guy

GuyWhats your db verzion. To over come the single quotes issue in string you can use q'[]' representation of string.
select q'[Karthick's]' from dual

How can I write a SQL statement which checks if a table exists?

How can I write a SQL statement which tells me whether a table exists?

execute an sql query: select * from <tablename>
catch the exception n check whether the erroe code
matches the one that occurs for table doesn't exist
that's itHow is your answer any different from the one given in the first reply?
It isn't.
As WorkForFood says DatabaseMetaData has a bunch of methods for getting information about tables but this is more useful when you don't know the names of any of the tables.. it sounds like you do so I would concur SELECT from table is probably the quickest way to go. If it helps the Xopen error should be either S1000 or 42S01 (I think) but I would try and see if there is a specific vendor code for table not found/not exists error and check for that.

How could I find the SQL statement who get this message ?

ORA-01555 caused by SQL statement below (Query Duration=11191 sec, SCN: 0x0854.723b9c32)
... How could I find the SQL statement who got this message ?
Thanks, Paul

ORA-01555 means that the UNDO/ROLLBACK space is not large enough.
This occurs because the SELECT statement is attempting to read the UNDO, but the UNDO has been released (transactions have committed or rolled back) and reused.
The following are SOME of the reasons I have seen this to occur:
1) Updates in a loop, with commits happening in the same loop
- this will mark the UNDO available quickly and quickly reuse it. Then when the SELECT wants to rebuild a block, the UNDO used to rebuild the block has been reused (solution, make the UNDO bigger)
2) A SELECT cursor used to control a loop in which updates are performed, and a 'done' flag is marked against the current cursor record, and commits are performed at the end of each loop, prior to fetching the next record
- same problem as above, but it hits the current process. Same solution
3) A 'month end' activity spike occurs, and all sorts of transactions create updates. There is a report that reports the activity - amusingly it needs to start at the beginning of all the work and updates periodically by doing a huge SELECT up front. This is then used to drive a loop which attempts to get information from the various transactions that have been updated and committed. After a while, the SELECT gets an ORA-01555
- same problem as above and same solution. Get a bigger UNDO segment.
You say this only happens once a month. That should give a hint.
I wouldn't bother with which SELECT statement, as much as which APPLICATIONs are being run when it happens.
One way around this - use 10g and set the guaranteed retention period. All sorts of other things will break, by no more 1555. <g>

How can i use one SQL statement to solve problem?

How can i use one SQL statement to solve the question below?
For a Table named A, there is a column named F(char type).
Now select all the records where F like '%00' and update their F value to '%01'
Just one SQL statement.Do not use PL/SQL block.
How to do that?
Thanks.

What is the data volume for this table?
Do you expect lots of rows to have '%00' as their value?
Following two statements come to mind. Other experts would be able to provide better alternatives:
If you have index on SUBSTR(f, 2):
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) || '01'
WHERE substr(f,
              -2) = '00';If most of the rows have pattern '%00':
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) ||
           DECODE(SUBSTR(f,
                         -2),
                  '00',
                  '01',
                  SUBSTR(f,
                         -2));

How can I execute Dynamic SQL statement in Forms?

Hi All,
I have to execute dynamic SQL statement from Forms
Below statement I have to execute
"EXECUTE IMMEDIATE v_stmt INTO v_return;".
Googled for the same got results saying, Better use Database function or procedures to execute these Dynamic Statements but We want to execute in forms only.
Can any one help me..
Thanks,
Madhu

So in short you are trading code obfuscation for maintainability and the ability to share code between tools? If from somewhere else you need a procedure already implemented in database PL/SQL (and now ported to forms) this would mean you'd need to implement it in every other tool. In times where you might want to integrate your forms with $other_technology and putting stuff on the database is the first step to share functionality you just go the opposite way? And all that because someone is afraid that somebody might steal your source code? I am sorry to be blunt, but this is just plain stupid.
Leaving aside that some things like Analytic Functions, Bulk processing or execute immediate are not even available in forms your software consists of how many LOC? How long does it take to bring a new developer up to speed with your source code? Imagine how long that would take for a developer who doesn't have coleagues who know their way around.
And just so you know: I work for a ISV selling a closed-source product as well. We have 200+ customers all over the planet. We are well aware that wrapped packages can be reverse engineered. The premise is: stored procedures can be reused in every tool we have, if it makes sense to put stuff on the database by all means do it. If someone would want to reverse engineer our software I'd wish him good luck as some parts are implemented in such a hilarious complicated way I have troubles understanding them (and quite frankly I refuse to understand certain parts, but that's another story). I do work for almost 10 years for that ISV.
In any case the possible solutions have already been mentioned: you have exec_sql, create_group_from_query and forms_ddl to execute dynamic SQL in forms whereas forms_ddl is a one way street and most certainly not the thing you need or want. Take a look at the documentation for the other 2 things.

How do i see the sql statements that are run ?

i want to see (in a log file) what are the sql statements that oracle had ran.
how do i do it ? what configurations should i do ? how ?
please help ... thanks

Current SQL statements are viewed in dynamic tables:
SELECT SCHEMANAME, SQL_ADDRESS, SQL_TEXT, last_call_et
FROM V$SESSION, V$SQLAREA
WHERE V$SESSION.SQL_ADDRESS=V$SQLAREA.ADDRESS
A historical log of all SQL statements is recorded in Oracle Archived Logs, and can be viewed using the Oracle Logminer approach. This process requires your database to be in ARCHIVELOG mode, and that Logminer be configured to read the archived logs.

How to run a single sql statement

I want to run a simple sql statement to get some data in my Controller or AM.
Is there some way, other than creating a VO with the SQL statement, to get some data from the database. My sql query will always return a single row.

Hi,
here you have an example I use to call a function in a package (note how you can pass parameters and read results):
Connection conn = this.getOADBTransaction().getJdbcConnection();
OracleCallableStatement ocs = null;
String param = null;
try {
        String stmt = "BEGIN :1 := <PkgName>.<FunctionName>(:2); end;";
        ocs = (OracleCallableStatement)conn.prepareCall(stmt);
        ocs.registerOutParameter(1, OracleTypes.CHAR);
        ocs.setString(2, <param>);
        ocs.execute();
        param = ocs.getString(1);
     } catch(SQLException se) {
         throw OAException.wrapperException(se);
     finally {
         try {
                ocs.close();
                return(param);
         } catch(Exception e) {
                throw OAException.wrapperException(e);
     }Hope this helps you

How to set client within SQL statement without using another pl/sql stmt.

I have a following select statement
SELECT SUM (w.prior_forecasted_costs + w.prior_committed_costs)
FROM xxsuf.job_cost_summary_table w,
apps.pa_periods p,
pa.pa_resources bz,
pa.pa_resource_list_members cz,
pa.pa_tasks dz
WHERE w.project_id = z.project_id
AND w.task_id = dz.task_id
AND dz.task_number '98000'
AND w.resource_list_member_id = cz.resource_list_member_id
AND cz.resource_id = bz.resource_id
AND NOT EXISTS (SELECT NULL
FROM pa.pa_tasks zz
WHERE zz.parent_task_id = dz.task_id)
AND w.resource_list_member_id != 1000
AND p.period_name = w.pa_period
AND p.current_pa_period_flag = 'Y'
Above select statement uses pa_periods view which only works when I set my client using "exec DBMS_Application_Info.set_client_info(83);" in Toad or SQL*Plus session.
I was wondering how can I achieve it within select statement. so that I don't have to use another PL/SQL statement to set my client. Is there anyway to set client with my org id within above select statement ?
Please advise.
--Rakesh

You can simply create a function which calls dbms_application_info and use that in your sql statement as in
SQL> create or replace function set_client_info (i_info varchar2)
   return varchar2
as
begin
   dbms_application_info.set_client_info (i_info);
   return i_info;
end set_client_info;
Function created.
SQL> create or replace view v_emp
as
select * from emp where empno = to_number(sys_context('userenv','client_info'))
View created.
SQL> select ename from v_emp where set_client_info(7788) is not null
ENAME
SCOTT
1 row selected.
SQL> select ename from v_emp where set_client_info(7900) is not null
ENAME
JAMES
1 row selected.

How to tune the following sql statements which has two unions in oracle 10g

It takes a long time to run the following sql statement in 10g. Each select brings back about 4 million rows and there will be about 12 million rows. When I run each select statements seprately in sqlplus I can see the data immedaitely but when I run it as whole with two unions in the select it just takes very very long time? I want to know how to make this run faster? Can we add hints? or is it because of any table space? Any help is appreciated.

Hi,
What i observed is that your table name and where clause is same in all the thress SELECTs whereas columns having some manipulations that is not going to be unique. I guess you can easily replace UNION with UNION ALL.
from PS_EARNINGS_BAL D
where D.SPCL_BALANCE = 'N'Note: I am not aware of your data and business requirement. Please test the result before removing. It is just a suggetion

How to get the real SQL statement from a preparedstatement?

Hi,
I am trying to log the actual SQL sent to database by the preparedStatement. Since the original SQL I used to prepare the statement has a lot of "?" in it, after setting all the parameters in the preparedStatement, I want to get the final SQL statement executed. Is there a way to get it? Probably the SQL will depend on different drivers.
Thanks in advance.

Thanks, changhsu. I tried the tracing technique. But it only prints out the original SQL statement sent to the preparedStatement. The following is part of the log file:

Since releasing 10.2.0.1 several years ago Oracle has released patches to 10.2.0.2, 10.2.0.3, and 10.2.0.4. I would highly recommend you read the patch notes and get your system current.
I note that you did not answer my two follow-up questions leading me to assume you do not have the license to look at the tables and views supporting ASH and AWR. Without them I do not believe you can retrieve the information you seek.
I no longer have 10gR2 on my laptop so I am not sure but take a look at gv$session.
Do you have columns named "BLOCKING_SESSION_STATUS", "BLOCKING_INSTANCE" and "BLOCKING_SESSION"? If you do that might lead you to a way you could track it down via gv$sql.

Should i use nested SQL Statements? or PL/SQL?

here is my table:
let's call this table total_stats, with 2 fields (columns) Date and Total.
Row | Total
ROW1 | 12508
ROW2 | 12526
I am going crazy trying to write some sql or pl/sql that will give me the following results: the result of row2Total - row1Total. I need the delta of the two Total's rows.
Is there an easy way to do this without writing multiple nested sql statments?
Should i write a procedure that uses cursors to help me get my end result?
thanks

Use analytic functions - LAG and LEAD - to access other rows in the result set in a current row. This should get you started:
SQL> create table total_stats as
2 select sysdate-1 as some_date, 12508 as some_value from dual
3 union all
4 select sysdate as some_date, 12526 as some_value from dual
5 /
Table created.
SQL> select * from total_stats;
SOME_DATE SOME_VALUE
12/11/2007      12508
13/11/2007      12526
2 rows selected.
SQL> select
2    some_date,
3    some_value as this_dates_value,
4    lag(some_value) over (order by some_date) as the_previous_dates_value
5 from
6    total_stats
7 /
SOME_DATE THIS_DATES_VALUE THE_PREVIOUS_DATES_VALUE
12/11/2007            12508
13/11/2007            12526                    12508

How to dynamic create Select SQL statements.

Hi frnds,
I want to make a SELECT statement in which all values I will get dynamically. Like i have two fields on selection screen, one for table name and one for field name. Now I need to make my ITAB according to the table selected and field name selected. So finally my ITAB will be having the field which I chosen from selection screen.
Now how can I make a dynamic ITAB and how to create a dynamic SELECT statement?
It wud be great if you can help me.
