Cursor in select query in row to column format
Hi
I have the query like below
SELECT d.department_id,
CURSOR(SELECT e.first_name,
e.last_name
FROM employees e
WHERE e.department_id = d.department_id
) emps
FROM depatments dI want the result set in a format of Row To columns like
10 20
<cursor result> <cursor result>pls give ur suggestions how to achieve this in a efficient way?I tried the method of "max(decode(.." but dont think so its possible with thisvishnu prakash wrote:

Must be known at the parsing time itself. But in your case i dont think the number of columns will be limited to 2 (10 and 20) there could be many more.
You can search this forum to see how to PIVOT your data. There are lot of example. You can also try dynamic pivot. Its all in here, just search. -
How to optimize the select query that is executed in a cursor for loop?
Hi Friends,
I have executed the code below and clocked the times for every line of the code using DBMS_PROFILER.
CREATE OR REPLACE PROCEDURE TEST
AS
p_file_id NUMBER := 151;
v_shipper_ind ah_item.shipper_ind%TYPE;
v_sales_reserve_ind ah_item.special_sales_reserve_ind%TYPE;
v_location_indicator ah_item.exe_location_ind%TYPE;
CURSOR activity_c
IS
SELECT *
FROM ah_activity_internal
WHERE status_id = 30
AND file_id = p_file_id;
BEGIN
DBMS_PROFILER.start_profiler ('TEST');
FOR rec IN activity_c
LOOP
SELECT DISTINCT shipper_ind, special_sales_reserve_ind, exe_location_ind
INTO v_shipper_ind, v_sales_reserve_ind, v_location_indicator
FROM ah_item --464000 rows in this table
WHERE item_id_edw IN (
SELECT item_id_edw
FROM ah_item_xref --700000 rows in this table
WHERE item_code_cust = rec.item_code_cust
AND facility_num IN (
SELECT facility_code
FROM ah_chain_div_facility --17 rows in this table
WHERE chain_id = ah_internal_data_pkg.get_chain_id (p_file_id)
AND div_id = (SELECT div_id
FROM ah_div --8 rows in this table
WHERE division = rec.division)));
END LOOP;
DBMS_PROFILER.stop_profiler;
EXCEPTION
WHEN NO_DATA_FOUND
THEN
NULL;
WHEN TOO_MANY_ROWS
THEN
NULL;
END TEST;The SELECT query inside the cursor FOR LOOP took 773 seconds.
I have tried using BULK COLLECT instead of cursor for loop but it did not help.
When I took out the select query separately and executed with a sample value then it gave the results in a flash of second.
All the tables have primary key indexes.
Any ideas what can be done to make this code perform better?
Thanks,
Raj.As suggested I'd try merging the queries into a single SQL. You could also rewrite your IN clauses as JOINs and see if that helps, e.g.
SELECT DISTINCT ai.shipper_ind, ai.special_sales_reserve_ind, ai.exe_location_ind
INTO v_shipper_ind, v_sales_reserve_ind, v_location_indicator
FROM ah_item ai, ah_item_xref aix, ah_chain_div_facility acdf, ah_div ad
WHERE ai.item_id_edw = aix.item_id_edw
AND aix.item_code_cust = rec.item_code_cust
AND aix.facility_num = acdf.facility_code
AND acdf.chain_id = ah_internal_data_pkg.get_chain_id (p_file_id)
AND acdf.div_id = ad.div_id
AND ad.division = rec.division;ALSO: You are calling ah_internal_data_pkg.get_chain_id (p_file_id) every time. Why not do it outside the loop and just use a variable in the inner query? That will prevent context switching and improve speed.

Cursor handle error in select query
Hello!
I'm having troubles with select query. I get the folowing error:
ODBC Error 'S1000', TimesTen Error 970, ODBC rc -1
ERROR in TTCommand.cpp, line 404: Error in TTCmd::Close() while closing cursor
[TimesTen][TimesTen 7.0.3.0.0 ODBC Driver][TimesTen]TT0970: Invalid cursor handle -- file "curAPI.c", lineno 1086, procedure "sb_curClose()"
*** ODBC Error/Warning = S1000, TimesTen Error/Warning = 970
*** Error in TTCmd::Close() for statement <SELECT 'alive' FROM DUAL>.
Error occures after aproximatelly 1000 request.
I' closing cursors and commiting after executing statement.
# ttisql -version
#TimesTen Release 7.0.3.0.0I use a code like described in sample.cpp in TimesTen demo directory.
First I prepare statement and function :
ControlData.Prepare(this, "SELECT 'alive' FROM DUAL", "", stat);
void
TTConnection::Control(TTStatus& stat)
TTStatus stat2;
try
ControlData.Execute(stat);
ControlData.Close(stat);
catch (TTStatus st)
cerr << "Error in SampleConnection::ContolData : " << st << endl;
ControlData.Close(stat2);
st.throwError() ;
In main function I use statement call like this (in endless loop)
try
conn.Control(stat);
conn.Commit(stat);
catch (TTError st)
cerr << "Error in CONTROL STATEMENT: " << st << endl;

Query in Select query operation
Please excuse me for posting this again.
I'm stuck up with this for 3 days. Lenghty post pls do read and help me.
How is the select query going to be changed in the SAP so that the original database behind it understands it. I want to know the operation of IN operation in where clause where in we can use ranges.
I'm asking this because I'm facing a problem using Native SQL.
Query is like this:
EXEC SQl.
OPEN C1 for
SELECT field1 from table@domain where field2 IN :ABAP_VAR.
ENDEXEC.
EXEC SQL.
FETCH C1 NEXT INTO :VAR1 , :VAR2
ENDEXEC.
Oracle usually recognises this statement IN ( '2222' , '3658' , '6895' )
But here this field that is build dynamically like this is not recognising them as seperate fileds but instead it is taking them as a single string and not selecting anything.
But if a single value is passed it is fetching the data into the cursor. And the code is working fine.
Any help in this is highly appreciable."if a in r_range" is is effectively: does the value held in 'a' comply with the values held in range 'r_range'. Ranges can hold NE, patterns etc so this can get quite complex.
You can see that it is very different from the SQL type IN.
If your range hold several values you could unstrip it into a string varaible so that it ended up having a value something like: ( '2222' , '3658' , '6895' ). Not sure if you need the '(' but it would be something like this:
eg,
assuming your range is simple and only holds 'I' and 'EQ' values:
data v_string type string.
loop at r_range.
concatenate v_string '@''' r_range-low '''@' into v_string.
endloop.
REPLACE
ALL OCCURRENCES OF '@'
IN v_string
WITH ' '.
Then you can use:
SELECT field1 from table@domain where field2 IN :v_string. -
In oracle rac, If user query a select query and in processing data is fetched but in the duration of fetching the particular node is evicted then how failover to another node internally?
The query is re-issued as a flashback query and the client process can continue to fetch from the cursor. This is described in the Net Services Administrators Guide, the section on Transparent Application Failover.

Error ORA-01652 while running select query
A select query returning millions of records is returning the following error.
SQL Error [
ORA-01652: unable to extend temp segment by 128 in tablespace TEMP
We requested DBA to increased the TEMP tablespace. He increased it to 20GB and also, changed to Autoextent.
When we executed the query again, we got the same error ?
What could be the reason of this issue and how it can be resolved ?All sort operations that don't fit into the SORT_AREA_SIZE will go to the temp tablespace (they can be seen as direct writes in the trace file).
It can easy be the case, that your temp tablespace needs to be many GB in size [we have a table with millions of rows and for the loading/merging our temp is 80GB in size].
May be you can change your process of loading i.e. with this select you fill a intermediate table (with CTAS) and do your processing there or even try to do the processing in SQL while building the table. You could also try to do the processing with a cursor and BULK COLLECT LIMIT 100 and then inserting into the target table with the FORALL statement. -

I nearly made a comment about how the plan doesn't show Bloom filter pruning either - and then I realised why not. The plan you've shown us comes from Explain Plan with literal values present; the trace file shows bind variables with names that are generated when cursor_sharing is set to force or similar - so the run-time plan and the plan from explain plan are almost guaranteed to be different.
Oracle support will need you to supply the plan you get from trying to run the query and then making a call to dbms_xplan.display_cursor() - dbms_xplan in 10g | Oracle Scratchpad If you do this I think you'll find that the pstart/pstop columns contain entries like :BF0000, and you may even find operations link PX JOIN FILTER CREATE / PX JOIN FILTER USE
A couple of generic notes:
if a query does sufficient work to merit parallel execution, then it's usually better to supply the best possible information to the optimizer, which means using literals rather than bind variables - you could try executing the query with the hint /*+ cursor_sharing_exact */ to stop Oracle from turning your literals into binds; it might be the presence of bind variables that's making the optimizer choose a path that has to include bloom filter pruning in your case.
Where you have the to_date() call you've used a four-digit year - which is a very good thing and helps the optimizer - but it's also a good idea to include an explicit format string as well: with a four-digit year this probably won't make any difference, but it avoids any risk of ambiguity for the optimizer.
I made a comment about the P->S stage and bottlenecks - I spent a couple more minutes looking at the plan, and I see the optimizer has used concatentation: in effect it has run three query blocks one after the other and fed the results to the query co-ordinator - in this case the P->S would make no difference to the end-user response time there's always a final P->S to the coordinator, you just happen to have three of them.

Needed help to improve the performance of a select query?
Hi,
I have been preparing a report which involves data to be fetched from 4 to 5 different tables and calculation has to performed on some columns also,
i planned to write a single cursor to populate 1 temp table.i have used INLINE VIEW,EXISTS more frequently in the select query..please go through the query and suggest me a better way to restructure the query.

How to create a Type Object with Dynamic select query columns in a Function
Hi Every One,
I'm trying to figure out how to write a piplined function that executes a dynamic select query and construct a Type Object in order to assigned it to the pipe row.
I have tried by
SELECT a.DB_QUERY INTO actual_query FROM mytable a WHERE a.country_code = 'US';
c :=DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(c,actual_query,DBMS_SQL.NATIVE);
l_status := DBMS_SQL.EXECUTE(c);
DBMS_SQL.DESCRIBE_COLUMNS(c, col_cnt, rec_tab);
FOR j in 1..col_cnt LOOP
DBMS_SQL.DEFINE_COLUMN(c,j,v_val,2000);
END LOOP;
FOR j in 1..col_cnt LOOP
DBMS_SQL.COLUMN_VALUE(c,j,v_val);
END LOOP;
But got stuck, how to iterate the values and assign to a Type Object from the cursor. Can any one guide me how to do the process.
Thanks,
mallikj2Hi Justin,
First of thanks for your reply, and coming to my requirement, I need to report the list of items which are there in the dynamic select statement what am getting from the DB. The select statement number of columns may vary in my example for different countries the select item columns count is different. For US its '15', for UK it may be 10 ...like so, and some of the column value might be a combination or calculation part of other table columns (The select query contains more than one table in the from clause).
In order to execute the dynamic select statement and return the result i choose to write a function which will parse the cursor for dynamic query and then iterate the values and construct a Type Object and append it to the pipe row.
Am relatively very new for these sort of things, welcome in case of any suggestions to make it simple (Instead of the function what i thought to work with) also a sample narrating the new procedure will be appreciated.
Thanks in Advance,
mallikj2. -
Problem in the "select" query....Just check out and help me
Hi there !!
I am getting the following errors while trying to execute the "select" query from JSP page:
java.sql.SQLException: [Microsoft][ODBC Driver Manager] Invalid cursor state
My code is :
String reg_no=(String)session.getAttribute("reg_no");
ResultSet rs=stmt.executeQuery("SELECT * FROM reg WHERE regno = "+reg_no);
(Note: the "regno" in the database is of numeric datatype)
Try to help me...
Thanx,
Ram.Just so everyone knows:
Ram Mohan joined the forum on 7-Sep-2003 and received
his 25 Dukes for joining.
Since then, he's posted three questions, each one
promising 5-10 Dukes, and never once awarded them.
His strategy seems to be to wave Dukes, ask his
hit-and-run question, and then bolt.
Answer his questions if you wish, but don't do it
expecting Dukes. - MODDuffy, you're getting just as cranky as I have. See what hanging around these forums does to oneself? :) -
Dynamic Select query is failing with error "Invalid Table Name"
OPEN rc FOR 'SELECT count(*) from :s' USING tab_name;
fetch rc into rec_count;
CLOSE rc;
my requirement is to build dynamic select query to retrieve the total count of rows in each table ( variable tab_name contains the table_name )
But I am getting stuck by this errror, not sure if there is any alternative !
ORA-00903: invalid table name
ORA-06512: at line 43OPEN rc FOR 'SELECT count(*) from '||tab_name;
fetch rc into rec_count;
CLOSE rc;
-- This will work
1. Create a sql statement.
2. Open ref cursor for that statement. -
Function as column in select query
Recently I came upon a couple of applications using Oracle database 10g that use functions as a column in a select query for reporting purposes. These queries were taking about 10 minutes to return 55,000 records. How can such queries be optimized where the functions in the queries cannot be modified?
Can the performance be improved at all without a re-design of the query?
SELECT
col1
,col2
,fn_get_val(col3)
,col4
,col5
FROM
table a,
table b
WHERE .....; The above function "fn_get_val" is defined as:
CREATE OR REPLACE fn_get_val(i_col IN VARCHAR2) return varchar2
as
CURSOR c ( i_var VARCHAR2 )
business logic here again
begin
OPEN c( i_col );
LOOP
Loop through the above cursor
EXIT; -- exit when condition satisfied.
END LOOP;
CLOSE c;
end;

SQL> So 1 execution of the function versus a 100 executions. But it is not always that straightforward and simplistic.
The ideal would be to not use a user function in the first place - but to instead apply that function's logic directly in SQL using native SQL statements. -
Delimited output of a select query
Hi, How to write comma delimited output
of select query from within a PL/SQL stored
procedure to a file. for example
select a | | ',' | | b
from test3
I know it can be done at SQL prompt using spool command, but
don't know how it can be done from within PL/SQL procedure without using cursors
thanks
PramodHi Pramod,
Why don't u try with use of UTL FILE.
select the necessary values into some local variables.
With the use of utl_file.fopen open a file.
And use utl_file.put_line to write the values
in to the file.
Try it and let me know.
Regards

SELECT query from within a stored procedure
DB Version:10gR2
For auditing purpose, i just want to execute the query within the IF condition, and get the results for spooling. But i am getting PLS-00428 error. Can't i just execute a SELECT query and get its results displayed in SQLPLUS so that i can spool them?

Errors for PROCEDURE ship_dtl_aud:
LINE/COL ERROR
14/11 PLS-00428: an INTO clause is expected in this SELECT statementWithin PL/SQL code, the results of a query have to be returned from the SQL engine to the PL/SQL engine, hence why it is asking you to include an INTO within your query. Note that the PL/SQL engine is running on the database server so it has no interface to display output to. To output from within PL/SQL you would have to write the data out yourself to whatever output you want e.g. use DBMS_OUTPUT to put the data to the standard output buffer (which can then be read by SQL*Plus if serveroutput is set to "on") or written out to a file on the server, or written out to a table.
You are assuming that because you can execute SQL from SQL*Plus and spool the output, you can do the same within PL/SQL. This is not the case. When SQL*Plus issues a SQL statement, it goes to the SQL engine and the results of that cursor (as an SQL query is a cursor) are collected by SQL*Plus and it displays them itself. When PL/SQL issues a SQL statement, it goes to the SQL engine and the results of that cursor come back to PL/SQL. PL/SQL doesn't have a display mechanism, so the results have to be collected INTO something.
Hope that's clear.
