Select from table of records

Hi,
Inside of a stored procedure I created:
- a record type:TYPE gr_rec IS RECORD (contact_id number)
- a table of records: TYPE gr_tb IS table of gr_rec INDEX BY BINARY_INTEGER
and then I populated the table in a loop: tb(i).contact_id := a.contact_id.
My question is:
Is it posible to perform a select statement on the table of records to get only distinct records?
If not, how can I filter these records, as I use the procedure as a block data source in a form and I need only distinct records.
Note: I can not obtain select rows from the query that populates the table.
Thank you, Monica

Look at this function:
create or replace type TYP_REC_EMP as object
EMPNO     NUMBER(4),
ENAME     VARCHAR2(10),
JOB       VARCHAR2(10),
MGR       NUMBER(4),
HIREDATE DATE,
SAL       NUMBER(7,2),
COMM      NUMBER(7,2),
DEPTNO    NUMBER(2)
create or replace type TYP_TAB_REC_EMP is table of TYP_REC_EMP
CREATE OR REPLACE FUNCTION Ret_Cur RETURN TYP_TAB_REC_EMP
IS
TAB TYP_TAB_REC_EMP := TYP_TAB_REC_EMP(NULL,NULL,NULL,NULL,NULL,NULL,NULL,NULL);
CURSOR C_EMP IS
SELECT *
FROM   EMP ;
i PLS_INTEGER := 0 ;
BEGIN
FOR CEMP IN C_EMP LOOP
         TAB.extend ;
        i := i + 1 ;
        TAB(i) := TYP_REC_EMP
                        CEMP.EMPNO,
                         CEMP.ENAME,
                         CEMP.JOB,
                         CEMP.MGR,
                         CEMP.HIREDATE,
                         CEMP.SAL,
                         CEMP.COMM,
                         CEMP.DEPTNO
END LOOP ;
RETURN TAB ;
END;

Performace Which is better ? : Bapi inside a loop OR Select from Tables

Hi Gurus,
I have a report which displays purchase info records.
If I am selecting from tables i need to use EINA, EINE, EORD and some other tables.
There is a BAPI which gets all purchase info records specific to a vendor , material , purchasing organisation.
QUESTION: Performace wise which is the better Approach, either selecting from tables or BAPI for Purchase info records
Regards
Avi.

Whether it using BAPI or select. you need to check the performance. If you have full key for these tables EINA, EINE, EORD then mak a select outside of the loop and within loop use READ TABLE statement with binary search. of if you want multiple records within loop then use loop insdie loop.
Your final objective is to minimise the database hits . If you use bapi inside loop then your database hits will be more
select from EINA
select from EINE
select from EORD
loop at itab,
read table EINA
read table EINE
read table EORD
endloop

Reason behind this query ,SELECT * FROM table WHERE 1 0

HEllo,
I would like to know the reason behind using this query ,
SELECT * FROM <table> WHERE 1 < 0
before executing the actual SQL query.
Is there any special reason or the JDBC receiver side is configured like that.
Is there any option to overcome this process like, can we remove this option or stop using this.
Why the JDBC adapter basically sending this query on the DB?
Thanks,
Soorya,

Hi,
if you run this query, you wont be able to see any records of the table.
SELECT * FROM <table> WHERE 1 < 0
if you run this query you will see all records
SELECT * FROM <table> WHERE 0 < 1
same with SELECT * FROM <table> WHERE 1=1
So you can check this out that whats happening in your code before executing actual query. just try to co-relate.

Html form for select * from table a

Hi all,
I m looking for report on header/footer part from one apex pages
which will display context from table a, like sql statement
select * from table a, written in html.
Is any examples in java script/html select from tables
(and same insert into table A (...) select * from table b)
thanks,
Gordan

Hello Gordan,
Do you want to show the whole report or just some data of it?
If it's for ex just the name and address you could create two items and have a process or computation to fill it with your select statement.
If it's the whole report, just create the report and put it in for ex. Region 1. In your page template you can specify that Region 1 needs to come into the footer.
Regards,
Dimitri

What is actually throwing the NullPointerException? rs.getMetaData() or table.setModel()?

How do I do SELECT * FROM TABLE WHERE KEY IN ({list})?

The title says it all really.
Is there a reasonable performant way to perform the query
SELECT * FROM TABLE WHERE KEY IN ({list})where {list} is String []?
I am currently creating a PreparedStatement with a for loop like this StringBuffer sb = new StringBuffer ("SELECT * FROM TABLE WHERE ID IN (");
for (int ii=0;ii<keys.length;ii++) {
sb.append (keys [ii]);
if (ii != keys.length-1) sb.append (",");
sb.append (")");but this means that the prepared statement is created each time I call my method and so I'm not sure that the optimizer will find it easy to cope with. Is there a construction that I'm missing along the lines of SELECT * FROM TABLE WHERE KEY = ? where I can create the PreparedStatement once and just call setObject or something on it when the values in {list} change?

but this means that the prepared statement is created
each time I call my method and so I'm not sure that
the optimizer will find it easy to cope with.You are right, the optimizer won't find that easy to deal with (presuming that is even relevant for your driver/database.) But most optimizers won't do anything with statements that change and that is what you are doing.
You could create several prepared statements which have a common number of bind variables. For example 10 statements with from 1 to 10 bind values. This will work if most of the queries use those.

Select from table containing clob

If i try to select from table containing clob column in SQL PLus it gives error.
Tab1 contains 3 clob columns and 1 blob column
select * from tab 1;
SP2-0678: Column or attribute type can not be displayed by SQL*Plus
The same statement works in SQL Developer and I am able to see the result.
Actually i am writing the queries and they will be used by Java developers in their JSP page.
So what happens here? Can Java use these select statements or will it throw error like SQL Plus?

BLOB column content can't be displayed in SQL*Plus:
SQL> create table t_blob (b blob);
Table created.
SQL> edit
Wrote file afiedt.buf
1* insert into t_blob values('01')
SQL> /
1 row created.
SQL> commit;
Commit complete.
SQL> select * from t_blob;
SP2-0678: Column or attribute type can not be displayed by SQL*PlusBlob and clob columns content can be processed using DBMS_LOB
package procedures and functions or using client's language (like Java)
methods. See JDBC specification.

Select * from table not working with Oracle OBDC driver

Hello,
In our web development we have been using the MS ODBC for Oracle
driver to connect to our Oracle db. We decided to try the
Oracle ODBC driver because it supports the commandTimeout
property in ASP which the MS driver does not. The problem I'm
running into now is that all of our select * from table
statements appear not to be working. The Oracle ODBC driver
version we are using is ver 8.00.05.00. Is there something that
I'm not doing properly? If I take the same select * from table
statement and name the columns, I dont get any error. Otherwise
I'm getting a Subscript out of range error. It seems strange to
me that this driver would not support a select * from table
statement (which I''m told is the case by another developer
here).
Is there something I'm missing?
Thanks,
Pete

I'm positive I have a connection. Otherwise I wouldn't get a
response when I name the columns instead of using *.
There must be something else that I'm missing or doing wrong.
I've actually been looking into alternative ODBC drivers to see
if I have the same problems but none that I have found support
commandTimeout.
Any other ideas?

Special Grant to use "Select * from Table(cast..."??

Hi,
I've recently created the types and function to use the Table(Cast(funtion) as type)). It works fine, and gives me the correct result. I've granted execute on the types and on the function to a role that is enabled for a user, but when the user tries to use the "select * from table(cast(function) as type))", he gets a "ORA-01031: Insufficient Privileges" error message. Is there any other grant that must be given to the role, so that the user can execute the select?
Thanks in advance!
Daniel

Hi Kamal,
I'm not sure what anonymous PL/SQL block means. When I (or the user) try to run the select, I enter all the information, i.e., the owners for the type and function: "select * from table(cast(a.my_function(my_argument) as a.my_type))". I'm trying to use SQLPlus at this time, and I have Oracle 8i.
I didn't to explicitly grant execute to the user because that would go against some rules I have to follow... I'll se if I give it a try though!
Thanks!

Expression Framework / SELECT * FROM TABLE(CAST(...

Hello!
Is it possible to build the following with Toplink Expression Framework?
Example:
CREATE TYPE TY_OB_TEST AS OBJECT
( SYSTOP_NR NUMBER(5,0)
SYS_NR NUMBER(5,0)
IM_SYS_NAME VARCHAR2(80) ) ;
CREATE TYPE TY_TB_TEST AS TABLE OF TY_OB_TEST;
Package1.FUNCTION1 returns Type TY_TB_TEST.
SQL:
select * from TABLE(CAST(PACKAGE1.FUNCTION1(42)) AS TY_TB_TEST ));
thank you!
Harald.

Nope, just use SQL.

Insert into table a (select * from table b) - need pk?

Hi there.
I'm going to insert into table FINAL (select * from table STAGING) - same structure but in STAGING the ID column has nulls.
Do I need to provide the ID (primary key) for table FINAL or will it get created based on sequence/trigger?
If I were doing this in a loop I'd get the next val from the sequence but on a simple insert, I'm curious.
thanks!

hmm.. what is ?
it didn't like it.

How to achieve that "SELECT * FROM table WHERE age BETWEEN 18 AND 23 AND n"

How to achieve the SQL like that "SELECT * FROM table WHERE age BETWEEN 18 AND 23 AND name = 'Will' " with BDB C-API
The primary key in the primary database is 'age' ,and the secondary key in the secondary index is 'name' ,in a lot of examples ,there are all simple , but how to do that complex one.thx~

but this means that the prepared statement is created
each time I call my method and so I'm not sure that
the optimizer will find it easy to cope with.You are right, the optimizer won't find that easy to deal with (presuming that is even relevant for your driver/database.) But most optimizers won't do anything with statements that change and that is what you are doing.

Can I simulate SELECT * FROM TABLE WHERE ROW IN (1111,2222) using SQLJ

I have a fct like
public void fct(String inStr) {
String str = "SELECT * FROM TABLE WHERE ROW IN" + inStr;
// then I xecute the query using JDBC connection
But I want to do the same thisn using SQLJ like:
public void fct(String inStr) {
#sql [nctx] iter = { SELECT * FROM TABLE WHERE ROW IN :inStr}
When I run the second version and give a parameter like "(1111,2222)" it gives
ORA-01722: invalid number error.
Is there a way to give parameters to in clauses of SQLJ statements.
Thanks in regard.

This is a SQLJ FAQ. You can find the FAQ at:
http://technet.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html
Your question is addressed in the following section:
http://technet.oracle.com/tech/java/sqlj_jdbc/htdocs/faq.html#variablesizevaluelist
Note that that section has a typo. The lines:
? // populate mynumbers
#sql { SELECT * FROM tab WHERE col in (:(a[0]),:(a[1]),?};
should read:
... // populate mynumbers
#sql { SELECT * FROM tab WHERE col in (:(a[0]),:(a[1]),...};
By the way, with the next release SQLJ will support pasting in of dynamic SQL fragments. Then you'll be able to do pretty much what you are trying to accomplish here (albeit with slightly different syntax). Until then you'd have to use the workarounds from the FAQ.

Select * from table where rownum 5; no rows returned? why is it so?

select from table where rownum > 5;*
no rows returned. why is it so?
can anyone explain me?

Hi,
rownum is pseudo column, and it is based on the sort order.
For ex, if you want to get the first 5 employees who get the least salary, you use,
select ename,sal from
    (select ename, sal
     from emp
     order by sal )
    where rownum<=5
ENAME      SAL
SMITH      800
ALLEN1     890
JAMES      951
TURNER     998
ADAMS      1100Suppose, if you want to use highest salary, you change the order by and not the rownum. So, it becomes,
select ename,sal from
    (select ename, sal
     from emp
     order by sal desc)
    where rownum<=5
ENAME      SAL
KING1      5000
FORD       3000
SCOTT      3000
JONES      2975
BLAKE      2850 So, its not the rownum you would want to change, but the order by.
