SQL within PL/SQL block

This question sound funny. I just want to make sure this rule. In Oracle database before 10g, we can only use DML and transaction control code within PL/SQL block. We can not use DDL or other control languages within PL/SQL block. How about 10g? can I use DDL in PL/SQL block in 10g?
I have created a procedure to drop all materialized view. Drop object is DDL. I used a piece of code like this:
v_sql_stmt1 := 'DROP MATERIALIZED VIEW'||v_schema||'.'||x.mview_name;
EXECUTE IMMEDIATE v_sql_stmt1;
The procedure was compiled successfully. However, when I run this SP, it generate ORA-00905 missing keyword error on EXECUTE IMMEDIATE statement part. Is this caused by missing keyword in sql statement or DROP as DDL can not be used in PL/SQL block? If it is first one, what is the keyword for DROP MATERIALIZED VIEW statement?

The versions of Oracle that run on this planet have been able to do DDL in PL/SQL for quite some time now. The DBAs who blasted off into space with you and worked in a vacuum the past however many years you feel you've been limited by this need to be replaced or re-introduced to Oracle.
For what it's worth, the error looks like you're missing a space.

Dynamic SQL within a SQL Query ?

is there any possibility to do like this ?
SELECT table_name, XXXXXXXX('SELECT Count(*) FROM '||table_name) tot_rows
FROM dba_tables
WHERE owner = 'SCOTT';or any other trick to run dynamic SQL within the SQL Query?
Hoping....that it should be.
Regards,
Orapdev

One small disadvantage: it is executing 202 SQL statements: 3 "user SQL statements" (the one above and the 2 "select count(*)..."), and 199 internal ones ...How did you get to those numbers?
I just traced this statement and found completely different results:

Display results of SQL in an HTML Block

Hi there
I want to display the results of some SQL within an HTML Block. To do this I have created a hidden page item which I can then reference within the HTML Block (ie: &mypageitem.)
However I want to run a process that assigns that page item the results of a simple SQL query that returns multiple rows. If I try to do that SQL within the page item itself it only assumes the value of the first row returned. I tried to do it within a pl/sql process and looping through a cursor and assigning my page item each row of the cursor. That didnt work because I couldnt insert an HTML BR within the page item and it only seemed to return one row.
Am I going about this the wrong way? Thanks in advance for any help.

Hi,
Firstly, you should declare a VARCHAR2 variable to hold the output. Secondly, when looping through the data, you should append each row's data to this string. Each line can be terminated using CHR(13) to get the new line. Finally, you set the field's value to the variable:
DECLARE
vOutput VARCHAR2(4000);
cursor definition etc
BEGIN
vOutput := '';
open the cursor...;
LOOP
vOutput := vOutput || rowdata || CHR(13);
END LOOP;
:mypageitem := vOutput;
END;

Performance issue while wrapping the sql in pl/sql block

Hi All,
I am facing performance issue in a query while wrapping the sql in pl/sql block.
I have a complex view. while quering the view using
Select * from v_csp_tabs(Name of View I am using), it is taking 10 second to fetch 50,000 records.
But when I am using some conditions on the view, Like
Select * from v_csp_tabs where clientid = 500006 and programid = 1 and vendorid = 1, it is taking more then 250 secs. to return the result set.
now the weird part is this is happening only for one programID, that is 1
I am using Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
Any one please suggest what are the things i need to check..
I am sorry, I could not provide you the explain plan, because this is in production and I do not have enough prevelage.
Thank you in advance.
Thnx,
Bits

HiddenName is correct in suggesting that you need to get execution plans but sometimes getting privileges from the DBA group is simply Not Going To Happen. Its wrong but that's the way it is. Follow through on HiddenName's suggested to get help from somebody who has the privleges needed
Post the query that view view is executing. Desk checking a query is NOT ideal but is one thing we can do.
I don't suppose you can see V$ views on production - V$SQL and V$SQL_PLAN (probably not if you can't generate plans, but its worth a thought)

SEQUENCE Select within an SQL Query with an ORDER BY statement

Does anyone know why you cannot use an ORDER BY statement within an SQL query when also selecting from a SEQUENCE? My query was selecting production data as a result of a filtered search. I want to take the results of the filtered search and create a transaction. I have a sequence for generating transaction numbers where I select NEXTVAL. Since I could possibly obtain multiple, yet distinct, rows based upon my search criteria, I wanted to use an ORDER BY statement to simplify and order the resulting row(s).
I was able to get the SQL select with SEQUENCE.NEXTVAL to work without the ORDER BY, so I know that my SQL is correct. Thanks in-advance.

Okay,
I understand. You want the sequence assigned first and the you want to ORDER BY. You
can do this using pipelined functions. See here:
CREATE OR REPLACE TYPE emp_rec_seq AS OBJECT (
   seq     NUMBER,
   ename   VARCHAR2 (20),
   job     VARCHAR2 (20),
   sal     NUMBER
CREATE OR REPLACE TYPE emp_tab_seq AS TABLE OF emp_rec_seq;
CREATE OR REPLACE FUNCTION get_emp_with_sequence
   RETURN emp_tab_seq PIPELINED
IS
   my_record   emp_rec_seq := emp_rec_seq (NULL, NULL, NULL, NULL);
BEGIN
   FOR c IN (SELECT dummy.NEXTVAL seq, ename, job, sal
               FROM emp)
   LOOP
      my_record.seq := c.seq;
      my_record.ename := c.ename;
      my_record.job := c.job;
      my_record.sal := c.sal;
      PIPE ROW (my_record);
   END LOOP;
   RETURN;
END get_emp_with_sequence;after that, you can do a select like this:
SELECT seq, ename, job, sal
FROM TABLE (get_emp_with_sequence)
order by enamewhich will get you this:
       SEQ ENAME                JOB                         SAL

Possible to have multiple data sources within 1 SQL querey?

Hi All,
Is it possible to join to a table in a different datasource within 1 SQL Querey?
Something like...
Connection 1
Select *
From Table
Join
Connection 2
On
Connection1.Table1.Field1 = Connection2.Table2.Field2 Thanks,
John

Johnbr (Oracle11G) wrote:
Is it possible to join to a table in a different datasource within 1 SQL Querey?Called distributed joins - joining a table from one database with that of another database. Also possible to do heterogeneously across different database products - e.g. joining an Oracle table with a SQL-Server table.
As already explained, some kind of communication interface is needed from the local database to the remote database, in order for the remote table to be read and joined to the local database. This interface is called a database link in Oracle.
The basic steps. First define the database link:
create database link <linkname>
connect to <account>
identified by <password>
using <connection-string>Complete syntax details and examples are in the SQL Reference Guide (see http://tahiti.oracle.com)
After the database link has been identified, you should now be able to address remote tables as follows:
select * from <remote-table>@<link-name>A distributed join would look something like the following:
select
from <local-table> t1,
<remote-table>@<link-name> t2
where t1.. = t2..However... this is almost always a BAD IDEA to do distributed joins. It seldom performs well. Performance is immediately constrained to the speed, bandwidth and latency of the network link between local and remote databases. It cannot scale with data volumes and increased frequency of use.
So if the remote table is not small, the network link not robust and reliable, and join not infrequent, it is bad idea to make use of distributed joins. In which case other alternative (and far superior) features need to be considered instead - like materialised views.

System command from within PL/SQL on server ?

Hi
I know its a bit weird thought of executing an NT system command from within PL/SQL on server (UNIX).
Has anyone done something (silly me!) like it or knows any work-around to try something like it?
Thanks in advance.
Regards
Pravesh

Can you be more specific?
Generally to run system commands you utilize DBMS_PIPE to communicate with a listener on the platform that you're accessing. That listener picks up the pipe request and might either:
1. spawn a process to run the command
2. fork a process to run the command
3. run the command within its own application.
It sounds complex, but if review the DBMS_PIPE documentation and it's not too difficult -- presuming you know a language like C.
I believe there are other features in 8.1.5 and higher versions that enable you to run stored programs or COM objects...

Error when trying to truncate table from within PL/SQL

Hello.....
Does anyone know why I get an error when trying to execute the following command from within PL/SQL?
truncate table event;
The error is as follows:
ORA-06550: line 20, column 14:
PLS-00103: Encountered the symbol "TABLE" when expecting one of the following:
:= . ( @ % ;
The symbol ":= was inserted before "TABLE" to continue.

And as a DDL, it does a COMMIT just before it runs. Whether you want a COMMIT or not.
And with all the locking and serialization issues associated with a DDL.

Find within pl/sql source objects

*

Hello,
do you mean all .sql files on the server or within pl/sql source objects ?
PL/SQL objects like packages are not stored in .sql files but compiled and can be viewed in user_source. So you would have to extract them to a file and execute after changing to get them back into the db. How would you handle this with your version control?
Or do you have sql files stored in CLOBs that are executed? Then you can update them in the database directly.

Using OS Commands within PL/SQL

How can I use Operating system commands from within PL/SQL procedures or functions? Kindly explain with an example.
Thanx,
SB

Previously we have used external procedures to use Windows kernel32.dll to start an external program. However this does not work on Oracle9i.
Instead I have modified an example in Java to acceive this. The following class can start an external program either synchronously or asynchronously and in synchronous mode it will return the programs output.
import java.io.*;
import java.util.*;
public class util
// Executes an operating system command. The command shall be fully qualified.
// The Java connects with silent login. No environment set-up files are run
// and no path is set. The mode can be "sync" or "async" for respectively
// synchronous and asynchronous execution
static public int OSCmd(String cmd, String mode, String[] output)
throws IOException, InterruptedException
System.out.println("OSCmd "+cmd+" ("+mode+")");
output[0]="";
// start command
Process proc = Runtime.getRuntime().exec(cmd);
if (mode.equals("sync"))
// get command's stdout and stderr
InputStream stdout = proc.getInputStream();
InputStream stderr = proc.getErrorStream();
String str;
// Stdout
BufferedReader br = new BufferedReader(new InputStreamReader(stdout));
while ((str = br.readLine()) != null)
output[0]+=str+"\n";
br.close();
// Stderr
br = new BufferedReader(new InputStreamReader(stderr));
while ((str = br.readLine()) != null)
output[0]+=str+"\n";
br.close();
// wait for command to terminate
proc.waitFor();
return proc.exitValue();
return 0;
You need the following permissions:
call dbms_java.grant_permission('COMMON', 'SYS:java.io.FilePermission', '<<ALL FILES>>', 'execute');
call dbms_java.grant_permission('COMMON', 'SYS:java.lang.RuntimePermission', 'writeFileDescriptor', '');
call dbms_java.grant_permission('COMMON', 'SYS:java.lang.RuntimePermission', 'readFileDescriptor', '');
And then create the Java stored procedure:
create or replace function os_cmd2(p_cmd varchar2, p_mode varchar2, p_output in out varchar2) return number
as language java
name 'util.OSCmd(java.lang.String, java.lang.String, java.lang.String[]) return int';

How to ftp a file within PL/SQL procedure?

Hi, all:
Any idea of how to ftp a file within PL/SQL procedure? I have scheduled a job to periodically generate a file and want to ftp this file to another machine. I know crontab can do the ftp part, since we can send email within Oracle, I am wondering whether we can ftp within Oracle as well? Thanks a lot!

Synchronous processes within pl/sql

Is there a directive or some mechanism within pl/sql where you can kick-off a process and not have to wait for it to complete in order to continue your main procedure?
I am thinking of this scenario for a pl/sql procedure (in simple terms):
1. Build a cursor to retreive records.
2. Within a loop, bulk collect 100 of the records into a collection.
3. If result set is not empty, send those 100 records off to be processed in a called procedure.
4. Without waiting for the called procedure to complete, bulk collect another 100 records and send those off to be processed.
5. End the loop and the main procedure when the result set returned is empty. The spawned procedures may or may not still be executing.
I know you can do this in Java, but I want to do it in Pl/SQL (10g).
Any ideas?
