Selecting a small number of rows

Hello,
I am looking for something in PL/SQL that will allow me to return a limited number of rows. In other SQL's this might be something like:
set row count=100
select * from tab1 --- returns first 100 rows found

SQL> select * from emp;

Select a specific number of rows in query

How can a specific number of rows be selected in a query? For example, a query retrieves 30,000 records and I want to retrieve the output by groups of 5,000. I want the query to retrieve the first 5,000 records, then the next 5,000 records etc. I tried rownum but that does not work.
Thanks,

Dynamic Select with different number of rows

Hi all,
I have a procedure who receives a table name and array of column names of that table.
I need to create a specific select statement with this parameters. Of course, this could change because the number of column names may differ from each invocation the this procedure.
Here's my procedure:
PROCEDURE column_scramble (pv_table_name
VARCHAR2,
ptbl_col_names
tbl_col_names)
IS
lv_query
VARCHAR2 (32000);
cur_handle INTEGER;
temp
NUMBER;
BEGIN
IF ptbl_col_names.COUNT > 0
THEN
lv_query := 'SELECT old.id, ';
FOR i IN ptbl_col_names.FIRST .. ptbl_col_names.LAST
LOOP
lv_query :=
lv_query
|| 'new.'
|| ptbl_col_names
|| ' as new_'
|| ptbl_col_names (i);
IF i < ptbl_col_names.LAST
THEN
lv_query := lv_query || ',';
END IF;
END LOOP;
lv_query :=
lv_query
|| ' FROM ( SELECT ROWNUM rr, '
|| pv_table_name
|| '.* FROM '
|| pv_table_name
|| ' ORDER BY '
|| pv_table_name
|| '.id) old, (SELECT ROWNUM rr, a.* FROM ( SELECT id,';
FOR j IN ptbl_col_names.FIRST .. ptbl_col_names.LAST
LOOP
lv_query := lv_query || ptbl_col_names (j);
IF j < ptbl_col_names.LAST
THEN
lv_query := lv_query || ',';
END IF;
END LOOP;
lv_query :=
lv_query

END IF;
DBMS_OUTPUT.put_line ('LV_QUERY: ' || lv_query);
cur_handle := DBMS_SQL.open_cursor;
DBMS_SQL.parse (cur_handle, lv_query, DBMS_SQL.native);

Avoid using the "cumbersome" DBMS_SQL, try this:
CREATE OR REPLACE TYPE tbl_col_names IS VARRAY (100) OF VARCHAR2 (40);
CREATE OR REPLACE PROCEDURE column_scramble
 ( pv_table_name VARCHAR2, ptbl_col_names tbl_col_names
 , pmy_cursor OUT SYS_REFCURSOR) --<<< NOTE: I added this parameter
IS
lv_query VARCHAR2 (32000);
cur_handle INTEGER;
temp NUMBER;
BEGIN
IF ptbl_col_names.COUNT > 0
THEN
 lv_query := 'SELECT old.id, ';
 FOR i IN ptbl_col_names.FIRST .. ptbl_col_names.LAST
 LOOP
 lv_query := lv_query || 'new.' || ptbl_col_names ( i)
 || ' as new_' || ptbl_col_names ( i);
 IF i < ptbl_col_names.LAST
 THEN
 lv_query := lv_query || ',';
 END IF;
 END LOOP;
 lv_query := lv_query ||
 ' FROM ( SELECT ROWNUM rr, ' || pv_table_name ||
 '.* FROM ' || pv_table_name ||
 ' ORDER BY ' || pv_table_name ||'.id) old
 , (SELECT ROWNUM rr, a.* FROM ( SELECT id,';
 FOR j IN ptbl_col_names.FIRST .. ptbl_col_names.LAST
 LOOP
 lv_query := lv_query || ptbl_col_names ( j);
 IF j < ptbl_col_names.LAST
 THEN
 lv_query := lv_query || ',';
 END IF;
 END LOOP;
 lv_query := lv_query || ' FROM ' || pv_table_name ||
 ' ORDER BY DBMS_RANDOM.VALUE) a) new WHERE old.rr = new.rr';
END IF;
DBMS_OUTPUT.put_line ( 'LV_QUERY: ' || lv_query);
OPEN pmy_cursor FOR lv_query;
END;
-- And to execute do this:
VAR my_cursor REFCURSOR;
DECLARE
emp_col tbl_col_names;
BEGIN
emp_col :=
 tbl_col_names (
 'DEPTNO'
 , 'MGR'
 , 'EMPNO'
 , 'ENAME'
column_scramble ( 'EMP3', emp_col, :my_cursor);
END;
PRINT my_cursor;

Selecting only required number of rows in an external table

Hi,
I have an external table with many flat files as source.. I know I can skip rows using the keyword 'SKIP'. I want to select only first 'n' rows from all the flat files as the rows available in my oracle external table. Is this Possible?...
eg..
Flat file 1
c1,c2
123,45
132,56
'ahgh',34
'dfd',22
Flat file 2
c1,c2
56,1212
545,45
'ahcsd',4
'dds',24
I want to create a file which contains the rows, means only the 2nd and 3rd rows from each flat files
123,45
132,56
56,1212
545,45
Thanks in Advance
Poulose

If this means selecting from all these flat files at the same time then it might get a bit cumbersome. Basically you will have to create an external table for each flat file and then do something like this:
SELECT * FROM
( select c1, c2 from
     ( select c1, c2, rownum as rn from ext_table_1 )
    where rn in (2, 3)
   union all
    select c1, c2 from
     ( select c1, c2, rownum as rn from ext_table_2 )
    where rn in (2, 3)
   union all
select c1, c2 from
     ( select c1, c2, rownum as rn from ext_table_3 )
    where rn in (2, 3)
   union all

How to control the number of rows selected from a sybase database table?

Hi, JDBC guru,
I'm working on project using Sybase 11.9.x database.We need to process a record in a table,first select it from the table,then do some computing,finally write it to a dbf file, if the above steps succeed,remove the original row in the table.Quite evidently, all these operation should be put into one transaction. But how can I select just a number of rows from the sybase database table?
Any hints?
Thank you in advance.

How to control number of rows displayed in a report by user?

Hi All!
I have provided a select list called 'Number of rows' in my report page.User can choose any number in the list, and accordingly he should be able to see so many number of rows in that report page.
For example: if user selects 50 from the list, he will be able to see 50 records at a time out of say 2000 records retrieved. I want to control number of rows displayed per page dynamically. And if he selects 25 in the select list, he should be able to see 25 records at a time out of 2000.
How to do it? Please give me ideas.
Thanking in advance.
Regards,
Deepika.

Hi Deepika,
If you have a Select List with Submit called, say "P1_ROWS", you just enter P1_ROWS into the Report Attribute's "Number of Rows (Item)" setting.

Select a set of random rows

I don't understand how the sample clause works on the select statement. Eg. SELECT * FROM clients SAMPLE(50) should return half of all rows in the table, but it's unstable. Sometimes it returns 4, sometimes 3 and even 2 (SELECT COUNT(*) FROM clients returns 6). Why???
So, if it's really unstable, how do I select a random number of rows from a query? Is there other way?

As noted, the number of rows returned by SAMPLE can vary. The approach I use is to set the sample number high enough so that the minimum number of rows it returns is always higher than what you want, and then chop off the excess with a rownum filter:
sql>select empno, ename, job
2 from emp sample (50)
3 where rownum <= 3;
 EMPNO ENAME JOB

How to get number of rows return in SELECT query

i'm very new in java, i have a question:
- How to get number of rows return in SELECT query?
(i use SQL Server 2000 Driver for JDBC and everything are done, i only want to know problems above)
Thanks.

make the result set scroll insensitve, do rs.last(), get the row num, and call rs.beforeFirst(), then you can process the result set like you currently do.
         String sql = "select * from testing";
         PreparedStatement ps =
          con.prepareStatement(sql,ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_READ_ONLY);
         ResultSet rs = ps.executeQuery();
         rs.last();
         System.out.println("Row count = " + rs.getRow());
         rs.beforeFirst();~Tim
NOTE: Ugly, but does the trick.

How can I limit the number of rows returned by a select stat

How can I limit the number of rows returned by a select
statement. I have a query where I return the number of stores
that are located in a given area.. I only want to return the
first twenty-five stores. In some instances there may be over
200 stores in a given location.
I know is SQL 7 that I can set the pagesize to be 25....
Anything similiar in Oracle 8i?

Can i get a number of rows in the select list??

Hello~
I am studying the "oracle call interface". but i don't know much about oci.
Anyway i want to know that how can i get a number of rows.
for example, there is a source code of the number of colums in the select list.
The following is a list of DB(example)
/*DB table*/
ID NAME CODE ID
1 A 1 A
2 B 2 B
/*source*/
err = OCIAttrGet ((dvoid *) stmhp, (ub4)OCI_HTYPE_STMT, (dvoid*)
&parmcnt, (ub4 *) 0, (ub4)OCI_ATTR_PARAM_COUNT, errhp);
/*result*/
The Column is 4. (ID, NAME, CODE, ID)
So, i think that the row is 3 (ID, 1, 2) in the DB table.
Simply, Can i get a number of rows in the select list??
for example,
err = OCIAttrGet ((dvoid *) stmhp, (ub4)OCI_HTYPE_STMT, (dvoid*)
&parmcnt, (ub4 *) 0, (ub4)OCI_ATTR_RAW_COUNT, errhp);
I'm trying to get the number of row count. but i can't find.
Please, could you let me know that how can i get the number of row count.
Thank you.

Thank you for your reply.
we are tested the source code by reply.
The following is the test source code.
/*source code*/
strcpy (szStatement, "SELECT * from DB_TABLE");
OCIStmtPrepare(gpOCIReadStmHandle, gpOCIErrHandle, szStatement,
strlen(szStatement), OCI_NTV_SYNTAX, OCI_DEFAULT);
OCIStmtExecute(gpOCISvcHandle, gpOCIReadStmHandle, gpOCIErrHandle,
0, 0, 0, 0, OCI_DEFAULT);
/* get a number of rows count , Reply : prajithparan*/
OCIAttrGet((dvoid *)gpOCIReadStmHandle, OCI_HTYPE_STMT, (dvoid *)&nRowCount, NULL, OCI_ATTR_ROW_COUNT, gpOCIErrHandle))
But There is a problem of the result value.
The result value is 0. It's mean that the row count is 0. and then we are using the all of fuction is succeed.(return value)
I don't know what is problem. Please let me know about the problem and solution.
Thank you.

Number of rows inserted is different in bulk insert using select statement

I am facing a problem in bulk insert using SELECT statement.
My sql statement is like below.
strQuery :='INSERT INTO TAB3
(SELECT t1.c1,t2.c2
FROM TAB1 t1, TAB2 t2
WHERE t1.c1 = t2.c1
AND t1.c3 between 10 and 15 AND)' ....... some other conditions.
EXECUTE IMMEDIATE strQuery ;
These SQL statements are inside a procedure. And this procedure is called from C#.
The number of rows returned by the "SELECT" query is 70.
On the very first time call of this procedure, the number rows inserted using strQuery is *70*.
But in the next time call (in the same transaction) of the procedure, the number rows inserted is only *50*.
And further if we are repeating calling this procedure, it will insert sometimes 70 or 50 etc. It is showing some inconsistency.
On my initial analysis it is found that, the default optimizer is "ALL_ROWS". When i changed the optimizer mode to "rule", this issue is not coming.
Anybody faced these kind of issues?
Can anyone tell what would be the reason of this issue..? any other work around for this...?
I am using Oracle 10g R2 version.

You have very likely concurrent transactions on the database:
>
By default, Oracle Database permits concurrently running transactions to modify, add, or delete rows in the same table, and in the same data block. Changes made by one transaction are not seen by another concurrent transaction until the transaction that made the changes commits.
>
If you want to make sure that the same query always retrieves the same rows in a given transaction you need to use transaction isolation level serializable instead of read committed which is the default in Oracle.
Please read http://download.oracle.com/docs/cd/E11882_01/appdev.112/e10471/adfns_sqlproc.htm#ADFNS00204.
You can try to run your test with:
set transaction isolation level serializable;If the problem is not solved, you need to search possible Oracle bugs on My Oracle Support with keywords

How can I get a fixed number of rows on a SELECT?

I'm interested on get the last xx records of one specific query that returns an higher number of rows than xx. How can I do this?

you can use "where rownum < xx" if you
write "select * from (select ... from ... order by ...) where rownum < 10"
but you can't write "rownum > 10" because no record will be returned.
therefor you have to do like this:
select * from (select ..., rownum as nummer from (select ... from ... order by ...)) where nummer > 10
