Help with PL/SQL arrays or Types
Hi,
I have a SQL query that returns the ID and the DESCRIPTION. I would like to loop through Ref Cursor and store these values into multi-array or something. What is the best way to achieve this? I appreciate your help.
ID DESCRIPTION
1 test1
2 test2
3 test3
Thanks..
You could use SELECT ... BULK COLLECT INTO arrayname, although for any serious volumes or concurrency it will take some redesign to avoid grabbing all the server's memory resources. Also I expect Billy will be along in a minute to tell you your approach is all wrong.
Why do you need an array?

Hi,
pretty new to Oracle and am not a programmer by profession.
Am trying to write a stored procedue that will create statements to
insert across a gateway, and have some of the insert statements
contain trims, depending on the column type.
so I am looping through one record at a time from dba_tab_columns.
Basically the below.
FOR tab in (
SELECT table_name,column_name,data_type
FROM dba_tab_columns where owner='MY_OWNER'
LOOP
END LOOP;
END;
But, what I really need to do is to loop all of the columns found for
each table into an array, so that at the end of the loop for each
table, one line is printed out something like this:
insert into my_table ( col1,col2 ... col_last) select col1,col2 ..
col_last from table@gateway_link.
The problem is in how to use the arrays to get each loop iteration to
be stored, and all printed out in one line at the end of each loop
iteration.
I hope I'm explaining this clearly enough. It sounds pretty simple,
but I am not able to figure it out.
Thanks for any help.
fwellers.I don't understand how you know which table is going to select from which remote table, but that's your problem
as a code-snippet, I'll give you the following idea:

3 l_tables tab_typ;
4 l_columns tab_typ;
5 l_str varchar2(4000);
6 cursor l_tab_cur is select table_name from all_tables where owner = 'SCOTT' and table_name in ('EMP', 'DEPT');
7 -- if you want to fill the table names, you could use str2tbl(tab_param)
8 cursor l_col_cur (p_tab_name varchar2) is
9 select column_name from all_tab_columns where owner = 'SCOTT' and table_name = p_tab_name;
10 begin
11 -- either set tables by hand;
12 l_tables := tab_typ('EMP', 'DEPT');
13 -- or fill it by a cursor
14 open l_tab_cur;

Java.sql.SQLException: Internal Error with oracle.sql.ARRAY getArray()
hi,
I am having having problems with the getArray() of oracle.sql.ARRAY.
Here are the details:
Oracle Database - 9.2.0.6. The JDBC driver used -10.2.0.1 jar.(the latest available).
I am calling a stored procedure from java, that has out param as a collection (VARRAY) of a user defined type.
The stored procedure works fine, if the user/schema used to connect,contains actual type, and i am able to extract the user defined object from the oracle.sql.ARRAY, via getArray().
But if i use a different user to connect which has public synonyms and execute rights to the actual type, i get the following error:

The problem is happening because we have 2 different users to connect to the database. one is the dba user, which contains all the types, packages and other one the application user, which we are supposed to use, to connect via java. This application user does have access to types via public synonym, but it gives the above mentioned error.
Please help :(.
Regards,
Gaurav.Hi avi,
Even I am getting the same error inspite of preceding the type name with the same user who has created the type.
It has displayed the array length.When I am trying to fetch each array, I am getting the error.
ARRAY simpleArray = (ARRAY) cs.getObject(3);
System.out.println("Array is of length " + simpleArray.length()); ********************** The above stmt prints 2 records ******************
But it goes to exception in the foll stmt..
Object [] objArrStructArray = null;
try{
objArrStructArray = (Object[]) simpleArray.getArray();
}catch(SQLException e){
e.printStackTrace();
Do u know abt this?
The foll is the error which I am getting.

Help with Oracle SQL to strip unwanted characters
Hello,
I have 2 columns (Weight and Height) where I need to strip the alpha characters and convert them to numbers (I am required to derive additional columns where I need to present
these values in inches, cm, KG, LB, etc. (and thus the need to convert them to numbers). I am too much a novice to understand the best way to convert these columns into numbers (same precision as you see here).
See the image below for a sample of what these columns currently contain. I simply need help with the Oracle SQL code to parse/convert these vales into number. Thanks in advance for your assistance!
DaveHi,
In addition to
Erland Sommarskog's comment which is of course correct and this i not the forum to ask question about Oracle, I dont want to leave you without a lead :-)
The solution both in SQL Server and Oracle should based on Regular Expressions. I highly recommended NOT to use T-SQL solutions in this case, as mentioned above, unless this is a very small table and the need is very simple and include finding one point
in the string as in
SaravanaC solution (when he assume thge string format is based on 2 parts (1) Number + (2) unit type).
In Oracle there is a build in Regular Expressions option as mentioned here: http://docs.oracle.com/cd/B12037_01/appdev.101/b10795/adfns_re.htm
In SQL Server the PATINDEX is used for simple cases and there is no built in Regular Expressions, but you can add it using CLR as shown in this link http://msdn.microsoft.com/en-us/magazine/cc163473.aspx

Help with: java.sql.SQLIntegrityConstraintViolationException
Hi, guys
I need help with the following exception: java.sql.SQLIntegrityConstraintViolationException: The statement was aborted because it would have caused a duplicate key value in a unique or primary key constraint or unique index identified by 'SQL090403155751200' defined on 'BOOK_ORDER'.
the things is my primary key is unique, so i checked the indexes and i found that i have two 'SQL090403155751200' indexes.
I would like to know:
1. can i delete the index without causing further database problems
2. what causes this problem and how can i avoid it.
By the way im using netbeans 6.5 and derby databaserizza_99 wrote:

By understanding what the application/system is supposed to be doing and the correctly creating indexes on the database that reflect the business needs.
Once you do that then the nature of the indexes that are needed are obvious.
You certainly don't delete indexes without that understanding however. -

Help with PL/SQl .....Sysdate-1
Hi all ..Need help with this
to_char(last_day(add_months(sysdate,-1)),'mm/dd/yyyy')
Its an Oracle 10g. We use two schemas out of many for Enterprise wide DW. They have 9 base tables in one of the schemas.. We have hundreds of views from that base tables . This SQL command is against one of the view . We basically need all the applications made by customers drilled by region,area,city etc. in the last month using this command.
Here we are using sysdate - 1 to retrieve reports for the last months data. These reports are run monthly on first business day once. But due to any problem if it runs after 3rd or 4th of the month it returns data from last months 3rd to this months 3rd which is logically wrong. Is there any solution so that whenever the report may run it has to return last months data from first of last month to last day of last month. It would be of great help if anyone gives the solution.
Thanks
TomTom,
Something like this
SELECT ADD_MONTHS (TRUNC (SYSDATE), -1)
- TO_NUMBER (TO_CHAR (ADD_MONTHS (TRUNC (SYSDATE), -1), 'DD'))
+ 1
first_date,
LAST_DAY (ADD_MONTHS (TRUNC (SYSDATE), -1)) last_date
FROM DUAL;Regards -
Anybody can help with this SQL?
The table is simple, only 2 columns:
create table personpay(
id integer primary key,
pay number(8,2) not null);
So the original talbe looks like this:
ID PAY
1 800
2 400
3 1200
4 500
5 600
6 1900
The requirement is to use one single query(no pl/sql) to show something lile the following, in other words, for each ID, the pay is the sum of all before itself and itself. So the query result looks like this:
ID PAY
1 800
2 1200
3 2400
4 2900
5 3500
6 5400
Again, just use one sql. No pl/sql. Anybody can help with this? I really appreciate that.
thanks,Eh, people are so "analytically minded" that can't even notice a simple join?
Counting Ordered Rows
Let’s start with a basic counting problem. Suppose we are given a list of integers, for example:
x
2
3
4
6
9
and want to enumerate all of them sequentially like this:
x #
2 1
3 2
4 3
6 4
9 5
Enumerating rows in the increasing order is the same as counting how many rows precede a given row.
SQL enjoys success unparalleled by any rival query language. Not the last reason for such popularity might be credited to its proximity to English . Let examine the informal idea
Enumerating rows in increasing order is counting how many rows precede a given row.
carefully. Perhaps the most important is that we referred to the rows in the source table twice: first, to a given row, second, to a preceding row. Therefore, we need to join our number list with itself (fig 1.1).
Cartesian Product
Surprisingly, not many basic SQL tutorials, which are so abundant on the web today, mention Cartesian product. Cartesian product is a join operator with no join condition
select A.*, B.* from A, B
Figure 1.1: Cartesian product of the set A = {2,3,4,6,9} by itself. Counting all the elements x that are no greater than y produces the sequence number of y in the set A.
Carrying over this idea into formal SQL query is straightforward. As it is our first query in this book, let’s do it step by step. The Cartesian product itself is
select t.x x, tt.x y
from T t, T tt
Next, the triangle area below the main diagonal is
select t.x x, tt.x y
from T t, T tt
where tt.x <= t.x
Finally, we need only one column – t.x – which we group the previous result by and count
select t.x, count(*) seqNum
from T t, T tt
where tt.x <= t.x
group by t.x
What if we modify the problem slightly and ask for a list of pairs where each number is coupled with its predecessor?
x predecessor
2
3 2
4 3
6 4
9 6
Let me provide a typical mathematician’s answer, first -- it is remarkable in a certain way. Given that we already know how to number list elements successively, it might be tempted to reduce the current problem to the previous one:
Enumerate all the numbers in the increasing order and match each sequence number seq# with predecessor seq#-1. Next!
This attitude is, undoubtedly, the most economical way of thinking, although not necessarily producing the most efficient SQL. Therefore, let’s revisit our original approach, as illustrated on fig 1.2.
Figure 1.2: Cartesian product of the set A = {2,3,4,6,9} by itself. The predecessor of y is the maximal number in a set of x that are less than y. There is no predecessor for y = 2.
This translates into the following SQL query
select t.x, max(tt.x) predecessor
from T t, T tt
where tt.x < t.x
group by t.x
Both solutions are expressed in standard SQL leveraging join and grouping with aggregation. Alternatively, instead of joining and grouping why don’t we calculate the count or max just in place as a correlated scalar subquery:
select t.x,
(select count(*) from T tt where tt.x <= t.x) seq#
from T t
group by t.x
The subquery always returns a single value; this is why it is called scalar. The tt.x <= t.x predicate connects it to the outer query; this is why it is called correlated. Arguably, leveraging correlated scalar subqueries is one the most intuitive techniques to write SQL queries.
How about counting rows that are not necessarily distinct? This is where our method breaks. It is challenging to distinguish duplicate rows by purely logical means, so that various less “pure” counting methods were devised. They all, however, require extending the SQL syntactically, which was the beginning of slipping along the ever increasing language complexity slope.
Here is how analytic SQL extension counts rows
select x, rank() over(order by x) seq# from T; -- first problem
select x, lag() over(order by x) seq# from T; -- second problem
Many people suggest that it’s not only more efficient, but more intuitive. The idea that “analytics rocks” can be challenged in many ways. The syntactic clarity has its cost: SQL programmer has to remember (or, at least, lookup) the list of analytic functions. The performance argument is not evident, since non-analytical queries are simpler construction from optimizer perspective. A shorter list of physical execution operators implies fewer query transformation rules, and less dramatic combinatorial explosion of the optimizer search space.
It might even be argued that the syntax could be better. The partition by and order by clauses have similar functionality to the group by and order by clauses in the main query block. Yet one name was reused, and the other had been chosen to have a new name. Unlike other scalar expressions, which can be placed anywhere in SQL query where scalar values are accepted, the analytics clause lives in the scope of the select clause only. I have never been able to suppress an impression that analytic extension could be designed in more natural way. -
Help with a Vector Array - pppppplllllllleeeeaaasse!!!!!!!
Hi I'm having a mare with a Vector Array that I want to contain String variables. I know you get a warning with the traditional implementation of a vector, and I have over come that using:
private Vector <String> MyVector = new Vector<String>();
But I also need to create a Vector Array and I am getting some very strange results - for a start in JPadPro it only comiles every second attempt, with every other failing due to the implementation of the Vector array.
Below is a snippet of the code that I have sort of got to compile but with a compiler warning:
private Vector<String>[] MyVector; //this is line 75
int Array;
public myClass()
Array = 5;
MyVector = new Vector[ Array ];
for( int i = 0; i < Array; i++ )
MyVector[ i ] = new Vector<String>();
The first time I complie I get:
CreateMessage.java Line 75: Syntax Error
The Second time I compile I get:
CreateMessage.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.
Finished
I hate complier errors - I have gotten quite a few but have managed to remove them all but this one by searching the forum. Any help on the correct implementation of my Vector Array would be great,
Thanks in advance,

I need help with the discoverer lineage.sql that allows hyper drill from V5 OWB Eul into OWB portal.
I am still on OWB 9.0.3 and seem to have a small version problem. the portal is up, and i can jump to portal reports from within the browser ok. I have created the eul definitions in disco using the bridge. the lineage work book is working but the url being generated is the wrong format for the portal.
Does anyone know how I can sort out the lineage url construction to parse the correct format?
thanks.
Richard.WOW! Nobody knows huh?
Well I'll let you know how I fixed it. Basically change the Disco Eul complex folder definition. After working out why the Url being contructed was wrong I changed the complex formula imbeded within the EUL object to parse the correct formula. And it now works. (I also added the hyperdrill for Impact analysis)
However the 9.03 repository is essentally a single table cmpallclasses and our table is huge. After getting the url parsing sorted, the actual underlying views were not returning data in a timely manner. Looking at the base table it has a single index, a quick bit 'o' tuning and having added three indexes my impact views return in under 2 mins which I am happy with. But my portal times out and spits out the no response from server which I think is an apache setting http.conf a generic time out. I am not sure why it may be a portal issue. I have set the owbportal to 1200 as a timeout, but something else is kicking in and killing the connex does anyone have a clue?
This is a big repository, I have around 1500 mappings now. Does anyone else have a production OWB repository of any real size?
Having sorted this out on 9.03, I am going to see how much I can apply to the 9.2 variant.
Thanks.

Help with DIgital Output Array with 6062E DAQ CARD...
Good morning, folks... I need some help with digital output of the 6062E PCMCIA card... I can output 1 line without problems... I need to control a 4066 with my digital outputs... I am doing this without greater problems... but there's something... I need that when one of my outputs is high, the others become low, unchangeably... so I tried to use an array to control my output and I couldn't do that... some errors showed up... can you help me please?

Problem with pl/sql table data type
hai friends,
i have one procedure it has some in parameters and one out parameter which fetches values to front end.
But the out parameter will be pl/sql table data type.
if it is ref cursor
then i declared as
var x refcursor;
exec procedure_name(1,:x);
it is ok.
but for pl/sql table data type is out parameter then what i will do in the prompt .
give me syntax and clarify my doubt.
advanced thanks...
madhavaThe SQL*Plus VARIABLE statement does not support user-defined types, hence it cannot support nested tables. It can support cursors because they can be weakly typed (so we can use the one SQL*Plus VAR to hold any shape of resultset). Nested tables are strongly typed; SQL*Plus is a relatively stupid interface and cannot be expected to understand UDT.
So, it you want to use nested tables as output you'll need to code a wrapping procedure that can understand your nested table type and handle it accordingly.
Sorry.
Cheers, APC -
Help with comparing string array with parameters
I've posted my code in full so hopefully everyone can see exactly what I have been doing.
Note - my code uses the observer/observable model. The method I am having the problem with the if statement is in the class HSBC.
Basically when the pin count reaches 4 (in the atm class) it sends the userid & pincode) over to the checkPinAndUserId(String pinCode, String userCode) method. Here the if statement should check the userid to see if the string parameter matches a string in the array. If it does it should check in the same position in the pin array to check the pin no is correct and then return true.

I'm new to java and have been told that using the observer/observable model is not considered basic java. So that is the only reason I posted it in this section. At the same time i feel that the bit I'm struggling with is actually basic - hence posting it in the basic section. I'm not sure if people of all abilities check all forums or just the ones they feel at at their standard.
So appologies if you've taken offence. -
Help with oracle sql to get all possible combinations in a table.
Hello guys I have a small predicatement that has me a bit stumped. I have a table like the following.(This is a sample of my real table. I use this to explain since the original table has sensitive data.)
CREATE TABLE TEST01(
TUID VARCHAR2(50),
FUND VARCHAR2(50),
ORG VARCHAR2(50));
Insert into TEST01 (TUID,FUND,ORG) values ('9102416AB','1XXXXX','6XXXXX');
Insert into TEST01 (TUID,FUND,ORG) values ('9102416CC','100000','67130');
Insert into TEST01 (TUID,FUND,ORG) values ('955542224','1500XX','67150');

Insert into TEST01 (TUID,FUND,ORG) values ('566653456','xxxxxx','xxxxx');
"TUID" "FUND" "ORG"
"9102416AB" "1XXXXX" "6XXXXX"
"9102416CC" "100000" "67130"
"955542224" "1500XX" "67150"
"915522211" "1000XX" "67XXX"
"566653456" "xxxxxx" "xxxxx" The "X"'s are wild card elements*( I inherit this and i cannot change the table format)* i would like to make a query like the following
select tuid from test01 where fund= '100000' and org= '67130'however what i really like to do is retrieve any records that have have those segements in them including 'X's
in other words the expected output here would be
"TUID" "FUND" "ORG"
"9102416AB" "1XXXXX" "6XXXXX"
"9102416CC" "100000" "67130"
"915522211" "1000XX" "67XXX"
"566653456" "xxxxxx" "xxxxx" i have started to write a massive sql statement that would have like 12 like statement in it since i would have to compare the org and fund every possible way.
This is where im headed. but im wondering if there is a better way.
select * from test02
where fund = '100000' and org = '67130'
or fund like '1%' and org like '6%'
or fund like '1%' and org like '67%'
or fund like '1%' and org like '671%'
or fund like '1%' and org like '6713%'
or fund like '1%' and org like '67130'
or fund like '10%' and org like '6%'...etc
/*seems like there should be a better way..*/can anyone give me a hand coming up with this sql statement...mlov83 wrote:
if i run this

"9148859fff" "1XXXXXX" "X6XXX" the last item should be excluded. The second digit in "org" is a "7" Fund is wrong, too. You're looking for 6 characters ('100000'), but fund on that row is 7 characters ('1XXXXXX').
and this is sitll getting picked up.That's why you should use the _ wild-card, instead of %
select tuid, fund, org
from test01
where '100000' like translate (fund, 'xX', '__')
and '67130' like translate (org, 'xX', '__')
;It's hard to see, but, in both calls to TRANSLATE, the 3rd argument is a string of 2 '_'s.
