SQL between clause & index question

I currently have the below CTAS that uses between clause to identify the date range from the parameter table and then query a history table on a different database. The history table has index in the acct_date column. The below SQL is slow and takes a long time.
create table temp1 as
select acct_date,cust_ord_1,fin_fclty_2,cust_ord_ship_3,
cust_ship_4,fin_item_5,sls_q,sls_tran_a
from pgt.pg_orders@jtu where acct_date between
(select value from pgm_parameters where parameter='wk_minday') and
(select value from pgm_parameters where parameter='wk_maxday');
Please advise of any changes that I can do to tune the script and make it execute faster. Thanks in advance.

Perf tuning issue with a query involving between clause

Hi all,
I am getting issues with performance when I try to execute this query. Given below the query and it is going for a full table scan. I think the problem is with the between clause. But I dont know how to resolve this issue
SELECT psm.member_id
FROM pre_stg_member psm
WHERE psm.map_tran_agn BETWEEN :start_transaction_agn and :end_transaction_agn
and psm.partition_key = :p_partition_key;
Having composite index on map_tran_agn and partition_key.
Please help me in this regard.
Thanks,
Swami

Please consider the following when you post a question.
1. New features keep coming in every oracle version so please provide Your Oracle DB Version to get the best possible answer.
You can use the following query and do a copy past of the output.
select * from v$version 2. This forum has a very good Search Feature. Please use that before posting your question. Because for most of the questions
that are asked the answer is already there.
3. We dont know your DB structure or How your Data is. So you need to let us know. The best way would be to give some sample data like this.
I have the following table called sales
with sales
as
      select 1 sales_id, 1 prod_id, 1001 inv_num, 120 qty from dual
      union all
      select 2 sales_id, 1 prod_id, 1002 inv_num, 25 qty from dual
select *
from sales 4. Rather than telling what you want in words its more easier when you give your expected output.
For example in the above sales table, I want to know the total quantity and number of invoice for each product.
The output should look like this
Prod_id   sum_qty   count_inv
1         145       2 5. When ever you get an error message post the entire error message. With the Error Number, The message and the Line number.
6. Next thing is a very important thing to remember. Please post only well formatted code. Unformatted code is very hard to read.
Your code format gets lost when you post it in the Oracle Forum. So in order to preserve it you need to
use the {noformat}{noformat} tags.
The usage of the tag is like this.
<place your code here>\
7. If you are posting a *Performance Related Question*. Please read
   {thread:id=501834} and {thread:id=863295}.
   Following those guide will be very helpful.
8. Please keep in mind that this is a public forum. Here No question is URGENT.
   So use of words like *URGENT* or *ASAP* (As Soon As Possible) are considered to be rude.

Still problem with SQL Between... Help me GURUS!

I've already posted this, but I will try to put it more simple:
Imagine these Tables:
Absentee Table
ID_TRABALHADORES (Number PK) (Trabalhadores=Worker in english)
DAT_INI_AUS (Date) - Initial date of absence
DAT_FIM_AUS (Date) - End of Absence
Justification Table
ID_TRABALHADORES (Number PK)
DAT_INI_JST (Date)
DAT_FIM_JST (Date)
Now imagine that an user (Thru a Oracle Form) inputs one absence from 2005/12/13 to 2005/12/29.
Now the user must input the specified Justification for that absence. Suppose there's 2 Justifications for one SINGLE Absence.
From 2005/12/13 to 2005/12/20 as justified as ilness and from 2005/12/21 to 2005/12/29 as Death of a relative.
If I want to find out if someone forgot to fill in a justification, or if it's wrong justified (wrong dates, etc...), how can I work the SQL with Between? It doesn't work if an user puts 1 Absence to 2 Justifications, because it reports it as being an error, but it's not, because the period is correct. It works fine if an user puts the example above like this:
Absentee Form:
2005/12/13 to 2005/12/20 (Ilness)
2005/12/21 to 2005/12/29 (Death of relative)
Justific Form:
2005/12/13 to 2005/12/20 - Ilness
2005/12/21 to 2005/12/29 - Death of relative
With this I don't catch it because it's not an error and the date periods are correct, but using this way:
Absentee Form:
2005/12/13 to 2005/12/29 (Ilness and Death of relative)
Justific Form:
2005/12/13 to 2005/12/20 - Ilness
2005/12/21 to 2005/12/29 - Death of relative
1 Absence to 2 Justific I catch it as error, but the period is also correct...
There's any SQL script that can turn around this problem?
PS- I don't want to use any sort of code in FORMS or PL/SQL

If I understand the question correctly, you are trying to find out if the justification data matches the absence data or not. Also, if the user puts in two absences then there should be two justifications, right?
Also, the date range of absence should match date range of justification.
The two tables are linked by ID_TRABALHADORES column.
One approach could be:
Figure out if the number of absence records and justification records match or not:
select ID_TRABALHADORES , count(*) from Absentee
group by ID_TRABALHADORES
MINUS
select ID_TRABALHADORES , count(*) from justification
group by ID_TRABALHADORES
This will give a list of all those IDs where :
1. There are more records in Absentee but fewer justifications, e.g. 2 date ranges but a single justification
2. User forgot to enter a justification
Now let's take it further ... I understand that you want to catch cases where the dates do not match for the IDs identified above.
select id, min(dat_ini_aus), max(dat_fim_aus) from absentee group by id
minus
select id, min(dat_ini_aus), max(dat_fim_aus) from justification group by id
If the date ranges match then the query above will eliminate further records as the date range identified by min/max would match.
Anything that does not match could be due to missing records, bad dates etc.
I think it will help if we can see more data samples and some more explanation of the problem you are trying to solve. A BETWEEN clause may not be needed here.

Help with SQL MODEL Clause

I have the privilege of performing a very tedious task.
We have some home grown regular expressions in our company. I now need to expand these regular expressions.
Samples:
a = 0-3
b = Null, 0, 1
Expression: Meaning
1:5: 1,2,3,4,5
1a: 10, 11, 12, 13
1b: 1, 10, 11
1[2,3]ab: 120, 1200, 1201, ....
It get's even more inetersting because there is a possibility of 1[2,3]a.ab
I have created two base queries to aid me in my quest. I am using the SQL MODEL clause to solve this problem. I pretty confident that I should be able to convert evrything into a range and the use one of the MODEL clause listed below.
My only confusion is how do I INCREMENT dynamically. The INCREMENT seems to be a constant in both a FOR and ITERATE statement. I need to figure a way to increment with .01, .1, etc.
Any help will be greatly appreciated.

Explanation:
Line numbers are based on the assupmtion that "WITH t AS" starts at line 5.
If you need detailed information regarding the MODEL clause please refer to
the Refrence site stated above or read some documentation.
Partition-
Line 18:     PARTITION BY (pt)
               This will make sure that each "KEY" will start at 0 for each value of pt.
Dimension-
Line 19:     DIMENSION BY ( 0 AS KEY )
               This is necessary for the refrences max_key[0], and min_key[0] to work.
Measures-
Line 21:      0 AS m_1
               A space holder for new values.
Line 22:     TO_NUMBER(SUBSTR(pt, 1, INSTR(pt, ':') - 1)) AS min_key
               The result is '1' for '1:5'.
Line 23:     TO_NUMBER(SUBSTR(pt, INSTR(pt, ':') + 1)) AS max_key
               The result is '5' for '1:5'.
Rules-
Line 26:     UPSERT
               This makes it possible for new rows to be created.
Line 27:     ITERATE (100000) UNTIL ( ITERATION_NUMBER = max_key[0] - min_key[0] )
               This reads ITERATE 100000 times or UNTIL the ITERATION_NUMBER = max_key[0] - min_key[0]
               which would be 4 for '1:5', but since the ITERATION_NUMBER starts at 0, whatever follows
               is repaeted 5 times.
Line 29:     m_1[ITERATION_NUMBER] = min_key[0] + ITERATION_NUMBER
               m_1[ITERATION_NUMBER] means m_1[Value of Dimension KEY].
               Thus for each row of KEY the m_1 is min_key[0] + ITERATION_NUMBER.

Of course, you can accomplish the same thing without MODEL using an Integer Series Generator like this.
create table t ( min_val number, max_val number, increment_size number );
insert into t values ( 2, 3, 0.1 );
insert into t values ( 1.02, 1.08, 0.02 );
commit;
create table integer_table as
select rownum - 1 as n from all_objects where rownum <= 100 ;
select
min_val ,
increment_size ,
min_val + (increment_size * n) as val
from t, integer_table
where
n between 0 and ((max_val - min_val)/increment_size)
order by 3
   MIN_VAL INCREMENT_SIZE        VAL
      1.02            .02       1.02
      1.02            .02       1.04
      1.02            .02       1.06
      1.02            .02       1.08
         2             .1          2

SQL IN clause with Bind parameter?

Hi
I have a simple task that hasn't been so simple to figure out. I want to allow a user to search for one or more comma-separated values in a simple JClient ADF app. Is there a way to use a SQL IN clause with a single bind variable? e.g. SELECT TITLE FROM CITATION WHERE ID IN (:0)
When I pass a single value it works fine but a comma separated list doesn't.
Thanks
John

Update: I wanted to combine the techniques found in two of Steve Muench's articles -
1) Providing Default Values for View Object Bind Variables (so I could display an ADF-bound JPanel with defaults)
http://radio.weblogs.com/0118231/stories/2004/10/07/providingDefaultValuesForViewObjectBindVariables.html
2) Array of String Domain Example (so a user could enter one or more comma-separated values into a text box for DB searches)
http://radio.weblogs.com/0118231/stories/2004/09/23/notYetDocumentedAdfSampleApplications.html
I learned some helpful stuff about the framework but spent lots of time banging my head against the wall because the two examples wouldn't work when directly combined. To best understand this, be sure to study Steve's examples above.
In example 1 Steve passes an array of objects (Object[] DEFAULT_VALUES) to the ViewObject's where clause using the setWhereClauseParams(Object[] values). However, in example 2 he creates an Oracle Array which contains an Oracle ArrayDescriptor, Connection, and array of values to pass to the "IN" bind variable. Also, example 1 allows for multiple bind vars to be included whereas example 2 allows for an array of data to be passed to a single bind var. Even though my code provides an array to a single bind var (per ex. 2) it should still allow for the passage of multiple bind vars with minimal code modification.
Code from Steve's example 1 was copied into my EmpView ViewObject but certain modifications were necessary:
1) Change the ViewObject's DEFAULT_VALUES from Object[] to String[].
2) Modify the executeQueryForCollection() method in the ViewObject to call a function which will set the bind variables as Oracle Arrays (effectively converting the "params" data type from that of String[] to Oracle Array[])
3) Create a setManagerID(String[]) method in the EmpView object and expose it to the client.
(there are a number of others so it's best for you to go through the code and compare)
I finally got it working so I'm attaching the code, however beware - I'm new to this so there may be other, better ways to go about it. Also, there are no framework bind vars so that section of code is never executed...it compiles but may fail at run time.
In order for this to work I suggest you use JDev to re-create the EmpView and Panel1 objects. This will ensure that the necessary ADF framework components are generated. Once complete, then copy in the code provided.

Help required in Index Question

Hi,
This is an interview question that i faced.
Theres a table Statistics having more than 300 columns. It has normal indexes on say five columns col1, col2, col3, col4, col5.
Queries involving the first four columns give excellent performance but the query involving col5 gives poor performance.
COL5 has around 5 million data and 1 normal index ix created on it and theres just one value in it say 'STATS'.(He said the query can be simple select queries or join queries, the queries may select all the rows of few rows may be 5%, 10% etc).
The question was what could be the possible reason?
I was unable to answer it but i think BITMAP index might be useful in this scenario.
Any help or suggestions will be highly appreciated.

Is it a good idea to creat a normal index on a column that have just one value as 'STATS' and the total no of rows is more than 5 million??

How to implement Select Between clause? ..help

Hi
I want to implent typical select between clause in the mappings. It is like i want to check whether the "Given date" exists between the range of dates. The range of dates is obtained from the various dimension tables. I dont know how implement that. please help.
Typical SQL query would be ....
and A."Month End Date" between dim.efcv_bgdt and dim.efcv_endt
and A."Month End Date" between dim2.efcv_bgdt and dim2.efcv_endt
and A."Month End Date" between dim3.efcv_bgdt and dim3.efcv_endt
and so on..............................
***************************************************************

Hi
Use a joiner operator and connect dim1, dim2, dim3 to it and in the join expression use your netween expression.
Or do you want to use the between in the select clause? Then use an expression operator and define a case when ... between ... and ... then ... else ... expression.

What is difference between sy-index and sy-tabix and where both are using ?

what is difference between sy-index and sy-tabix and where both are using ?

hi nagaraju
sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
SY-INDEX is a counter for following loops: do...enddo, while..endwhile
SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id Name
198 XYZ
475 ABC
545 PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.

Difference between sy-index & sy-tabix

Dear friends,
Please tell me the difference between sy-index & sy-tabix
Actually my problem is i don't know how to compare for example between first record'field n and second record'field n when u r in loop so i can take particular action based on result
on current recor
if possible send me sample code.
Regards;
Parag Gavkar.

SY-TABIX:
Current line in an internal table. With the following statements SY-TABIX is set for index tables. With hashed tables, SY-TABIX is not filled or it is set to 0.
- APPEND sets SY-TABIX to the index of the last table row, that is the total number of entries in the target table.
- COLLECT sets SY-TABIX to the index of the existing or appended table row. With hashed tables, SY-TABIX is set to 0.
- LOOP AT sets SY-TABIX to the index of the current table row at the beginning of every loop pass. After leaving a loop, SY-TABIX is set to the value it had before entering the loop. With hashed tables, SY-TABIX is set to 0.
- READ TABLE sets SY-TABIX to the index of the table row read. If no row is found with binary search while reading, SY-TABIX contains the index of the next-highest row or the total number of rows +1. If no row is found with linear search while reading, SY-TABIX is undefined.
- SEARCH itab FOR sets SY-TABIX to the index of the table row, in which the search string was found.
SY-INDEX:
SY-INDEX contains the number of loop passes in DO and WHILE loops, including the current loop pass.
Regards,
Santosh

How can I set a variable number of values in a SQL IN clause?

Hi,
How can I set a variable number of values in a SQL IN clause without having to change the text of the SQL statement each time?
I read the link http://radio.weblogs.com/0118231/2003/06/18.html. as steve wrote.
SELECT *
FROM EMP
WHERE ENAME IN (?)
But we need the steps not to create type in the system and would there be any other solution if we would like to use variable number of values in a SQL IN clause ?
We are using JDeveloper 10.1.3.2 with Oracle Database 10.1.3.2
Thanks
Raj

Hi,
can you please explain why the solution from steve is not the right solution for you.

Generate a SQL "IN" clause using ALDSP

Problem Summary
ALDSP: Generate a SQL "IN" clause
Problem Description
I would like to know if there is a possibility of generating an SQL "IN" clause using ALDSP.
I would need the XQuery construct to create an SQLsomething like-
select * from emp where dept_no in ('101', '201', '301');
The values for dept_no would be passed at runtime.
(Or)
Will be I able to create a physical data service using the SQL - select * from emp where dept_no in ?
If yes, how do I map the parameter to "?"
Thanks.

Mike,
Thanks for the response. The section that you are taking about is to push joins to DB. Joining tables is not the problem that I am facing.
I will rephrase the problem.
I would like to know if there is a possibility of creating a ALDSP physical data service (.ds file) with the SQL as select * from employee where emp_id in ?
and I should be able to pass multiple employee ids to the "?" parameter. select * from emp where emp_id in ('101', '201', '301');
There is no fixed number of ids that a user can pass.
Thanks.

SQL IN clause with a Tool variable

We are using using Forte 3.M.2 (just upgraded from 3.G, finally).
Platform is AIX 4.3. Database is DB2 (UDB) (version 5.2 i think).
True, I haven't tried my code on any other platform. I think it should work on NT, because one of our other teams members has set up an NT laptop for portable demos. And it has DB2 (NT version i guess) loaded on it.
Dynamic sql is not really that bad, if you have to go that route to build your list.
Let me know how it goes.

Daniel González de Lucas <danieleam.es> 07/28/00 04:06AM >>>We are getinng some trouble, the DB Manager seems to try to convert
:OfficeList to a unique integer lets say:
:OfficeList value is 3,4,7
so the IN clause
trying with Oracle 8.1.5 converts 3,4,7 in a unique integer (a extrange
value because doesn't match with 3,4 nor 7).
trying with SQL Server 6.5 gives an error converting 3,4,7 to a unique
tinyint.
The idea is that with your sintax the DB Manager must split the TextData
into 3 integer values. I think that it works fine in some DB Managers and
not in others.
Which release and vendor of DB Manager you use?
Which Forté release?
Thank you very much in advance.
Daniel.

I needed to have an "IN" clause for some numbers. Here's how I did it:
GetOffices():TextData method...
Offices : TextData = new ;
for (x : integer) in sql select MyIntegerColumn
from MY_TABLE
where whatever condition
on session MyDBSession do
Offices.Concat(x) ;
Offices.Concat(',') ;

return (Offices.CopyRange(0,Offices.ActualSize -1)) ; // get rid of lastcomma
in actual sql.....
OfficeList : TextData ;
OfficeList = GetOffices() ;
sql select * from MyTable where MyField in (:OfficeList)
on session MyDBSession ;
Works very well.
