Using accept command within PL/SQL block

Hi all i have a following Pl/SQL block which ia =as follows :-
declare
begin
...certain statements using while
end;
i need to take the user input using accept
if i put the accept stmt betweeen begin and end i am getting following error :-
accept myv number default 10 prompt 'Enter a number: '
ERROR at line 48:
ORA-06550: line 48, column 8:
PLS-00103: Encountered the symbol "MYV" when expecting one of the following:

ORA-06550: line 48, column 30:
PLS-00103: Encountered the symbol "PROMPT" when expecting one of the following:
* & = - + ; < / > at in is mod remainder not rem
<an exponent (**)> <> or != or ~= >= <= <> and or like
between || multiset member SUBMULTISET_
Let me know how can i include accept stmt in Pl/SQL block
Thanks

You're missing a fundamental concept here.
PL/SQL = embedded 4GL programming language in the Oracle database.
SQL*Plus = CLI (Command Line Interface) client for an Oracle database.
The ACCEPT command is a SQL*Plus command. Not a PL/SQL command.
The PL/SQL engine sits inside the Oracle Server Process that services your client (SQL*Plus) session. That server process does not know who/what/where you are as a physical client. It does not know what platform and o/s you are using. It does not know what client you are using. It is after all a server process and should not and need not to know that.
Nor can that Oracle Server Process running on the Data Server Platform access you client's hard drive, keyboard, mouse, screen, printer and so on.
PL/SQL running in this Oracle Server Process therefore cannot read your keyboard to accept end-user input. PL/SQL therefore cannot write data to your screen.
You need to make a clear distinction between SQL*Plus (a client) and Oracle PL/SQL (the server).

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';

Copy Command in Pl/Sql block

Can I use Copy command in Pl/Sql.For example :-
Declare
cursor c1 is select table_name from all_tables
where owner = 'LSP' and rownum = 1;
v1 varchar2(2000);
Begin
for c2 in c1 loop
v1:='copy from lsp/lsp123479@dvlaq to scott/[email protected] create '|| c2.table_name ||' using select * from '||c2.table_name;
execute immediate v1;
end loop;
end;
Its not running properly giving an error as invalid Sql statement .
Is it bcoz Copy command cannot be used in a Pl/Sql Block.

Is there any other way to move the Table & data to another Data Base .Database link is the obvious one. And the SQL statement would look something like this (on the target database):
SQL> create table FOO nologging as select * from FOO@sourcedb;
However, the first question I always ask if why? What one may think is the solution to a problem is not always the best solution. So one need to identify the problem first, and then see what solutions there are and which one is the best fit.
Other options are replication (using materialised views for example), Data Pump (available with 10G) - even could be Data Guard, a standby database, or a Real Application Cluster... depending on just what the problem and actual requirements are.
Also important to note that SQL*Plus has its own set of commands. Do not confuse these commands (like EXEC, COPY, CONNECT, HOST etc) with the SQL and PL/SQL Languages. Not only are they executed by different software products, SQL*Plus commands are executed on the client and SQL (and PL/SQL) runs inside the Oracle database instance.

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.

Use "set spool" command in pl/sql block

Hi,
I need to use the "set spool ..." command inside my pl/sql block.
could you please tell me how to do this.
Please help fast.
Thanks
Maria

I am aware that spool is not a pl/sql command.
I have to put the result of my query into a file without using util commands ( as I canot change the utl_file_dir). SO I was sondering if somehow I could use the pool command inside my pl/sql.
My data is too big to use dbms_output.
Thus can you suggest anything

PERFORMANCE BAD WHEN CURSORS ARE USED WITHIN PL/SQL BLOCKS

There are poor database performance at Oracle 10g
For some cursor selects, the performance is under Oracle 10g
significant slower than under Oracle 9i.On a test system (Oracle 9) the
problem does not reproduce, on the 10g system however always.
The simple execution of the base select statement was on both
databases in roughly of the same speed. If however a cursor was defined and
those executed within a PL/SQL block (without involving the user interface),
then the time behavior was in accordance with the observed behavior
behavior on the user interface.
By adding of the hint first_rows on both machines a
similar (fast) time behavior can be achieved.
Conclusion: Something in the (Optimizer) settings of the Oracle-10
databases must be fundamentally different than that of Oracle 9. Or Oracle
10 has a real problem. The analysis and solution of this general
problem seems to me more reasonable than the solution of individual performance
problems.
can you help me, many thanks

Hello, thanks for the explanatory notes.
Here are the concerned Script. The only difference is the Hint (with Hint = good püerformance; without Hint = bad performance)

Calling DBMS_STATS within PL/SQL block

Hy guys
I trying to call the package DBMS_STATS within a pl/sql block but I'm getting the following error..
here is my blok
BEGIN
IF FGLOBAL('ABC_STATS') = 'SIM' THEN
FOR V_OBJETOS IN C_CURSOR_STATS LOOP
EXECUTE IMMEDIATE 'EXEC DBMS_STATS.GATHER_TABLE_STATS('''||USER||''','''||V_OBJETOS.TABLE_NAME||''')';
END LOOP;
END IF;
here is the execution error
SQL> exec analisa_stats;
BEGIN analisa_stats; END;
ERROR on line 1:
ORA-00900: invalid SQL instruction
ORA-06512: on "username.ANALISA_STATS", line 12
ORA-06512: on line 1
How can I call the package using execute immediate ? is there any other way ?
Tks to All

Hi,
1. in pl/sql you cannot specify "exec dbms_stats ..." but only "dbms_stats ...".
2. why execute immediate, just call dbms_stats and pass your parameters
regards, martina

Exec SQLPLUS command from PL/SQL Block

Good Morning:
How I can execute a SQLPLUS command (like SPOOL or DESCRIBE) from PL/SQL Block Procedure?:
DECLARE
BEGIN
ls_command = 'DESCRIBE '||ls_table_name;
EXECUTE SQLPLUS(ls_command);
END;
Thanks a lot for any idea.

That's correct.
However, in the case of the given example we can use DBMS_DESCRIBE package to get table descriptions. And we can use UTL_FILE to spool PL/SQL stuff to a file.
Cheers, APC

Why named parameter can't be used multiple times in PL/SQL block in JDBC

with the following PL/SQL block, when I run int in JDBC, I get an error,
it says, The number of parameter names does not match the number of registered parameters.
if all named parameters are used only once, then my program works fine.
My old program uses Oracle Forms to run the attached PL/SQL block correctly, I just want to run them in JDBC without more efforts, I don't want to rewrite all PL/SQL blocks.
Does oracle driver support this case? why the PL/SQL block can work in Oracle Forms but failed in JDBC?
Can we have an another solutions to avoid rewriting the PL/SQL block to stored procedure?
if I use following SQL:
BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;
, Using java program:
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
in the coding, only "q" registered, I got:
java.sql.SQLException: The number of parameter names does not match the number of registered praremeters at oracle.jdbc.driver.OracleSql.setNamedParameters(OracleSql.java:314) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10096) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:28)
now, tried to register 3 indexes, changed fragments are below.
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :q := 'X'; else :q := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter(1, Types.VARCHAR); stmt.registerOutParameter(2, Types.VARCHAR); stmt.registerOutParameter(3, Types.VARCHAR); stmt.setString(1, "A"); stmt.execute(); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
now error changed to:
java.sql.SQLException: ORA-01006: bind variable does not exist at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:457) at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:400) at oracle.jdbc.driver.T4C8Oall.processError(T4C8Oall.java:926) at oracle.jdbc.driver.T4CTTIfun.receive(T4CTTIfun.java:476) at oracle.jdbc.driver.T4CTTIfun.doRPC(T4CTTIfun.java:200) at oracle.jdbc.driver.T4C8Oall.doOALL(T4C8Oall.java:543) at oracle.jdbc.driver.T4CCallableStatement.doOall8(T4CCallableStatement.java:208) at oracle.jdbc.driver.T4CCallableStatement.executeForRows(T4CCallableStatement.java:1416) at oracle.jdbc.driver.OracleStatement.doExecuteWithTimeout(OracleStatement.java:1757) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:4372) at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:4595) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10100) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:26)
, now tried register only 1 position like below,
CallableStatement stmt = con.prepareCall(SQL);   stmt.registerOutParameter(1, Types.VARCHAR);   stmt.setString(1, "A");   stmt.execute();
, it says:
java.sql.SQLException: Missing IN or OUT parameter at index:: 2 at oracle.jdbc.driver.OraclePreparedStatement.processCompletedBindRow(OraclePreparedStatement.java:2177) at oracle.jdbc.driver.OraclePreparedStatement.executeInternal(OraclePreparedStatement.java:4356) at oracle.jdbc.driver.OraclePreparedStatement.execute(OraclePreparedStatement.java:4595) at oracle.jdbc.driver.OracleCallableStatement.execute(OracleCallableStatement.java:10100) at oracle.jdbc.driver.OraclePreparedStatementWrapper.execute(OraclePreparedStatementWrapper.java:5693) at RunPLSQLBlock.main(RunPLSQLBlock.java:26)
, now let try a OK case, which use all named parameters only once. coding like below, SQL and Java listed below.
BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; EXCEPTION   WHEN NO_DATA_FOUND THEN     NULL; END;
import java.sql.*; public class RunPLSQLBlock { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL = "BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; END;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.registerOutParameter("r", Types.VARCHAR); stmt.registerOutParameter("s", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); System.out.println("Q :" + stmt.getString("q")); System.out.println("R :" + stmt.getString("r")); System.out.println("S :" + stmt.getString("s")); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the case give us the following output:
Q :A R :null S :Y
2nd part, I also tried another scheme, to use 'execute immediate', test code attached below, it also have errors.
begin execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out :q, out :r; end;
, Java Code:
import java.sql.*; public class RunDynamicSQL { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL ="begin execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out :q, out :r; end;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter("q", Types.VARCHAR); stmt.registerOutParameter("r", Types.VARCHAR); stmt.setString("q", "A"); stmt.execute(); System.out.println("Q :" + stmt.getString("q")); System.out.println("R :" + stmt.getString("r")); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the output is, we can find when parameter 'q' is IN OUT mode, we can't get its final value:
Q :null R :Z
, now I tried my workaround, it works fine by using a temporary variable, now my named parameter is split to 2 roles, one is for IN, another is for OUT, now I can get final out value.
declare q clob; r clob; begin q := ?; r := ?; execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out q, out r; ? := q; ? := r; end;
, my test java code,
import java.sql.*; public class RunDynamicSQL { public static void main(String s[]) throws SQLException { String URL = "jdbc:oracle:thin:@192.168.11.199:1521:TIBSTEST"; Connection con = null; try { Class.forName("oracle.jdbc.driver.OracleDriver"); con = (Connection) DriverManager.getConnection(URL, "FBP1DEV", "FBP1DEV"); String SQL ="declare q clob;r clob; begin q := ?; r := ?; execute immediate 'begin if :q is null then :q := ''X''; else :q := ''Y''; :r := ''Z''; end if; end;' using in out q, out r; ? := q; ? := r; end;"; CallableStatement stmt = con.prepareCall(SQL); stmt.registerOutParameter(3, Types.VARCHAR); stmt.registerOutParameter(4, Types.VARCHAR); stmt.setString(1, "A"); stmt.setString(2, "A"); stmt.execute(); System.out.println("Q :" + stmt.getString(3)); System.out.println("R :" + stmt.getString(4)); } catch (Exception e) { e.printStackTrace(); } finally { if (con != null) { con.close(); } } } }
, the output is expected,
Q :Y R :Z

Hi, thanks for your response, now I see, the named parameter is for stored procedure only, for PL/SQL block we name it placeholder name.
After cast my java.sql.CallableStatement to oracle.jdbc.OracleCallableStatement, I can find setStringAtName,
now, I have only one question:I can't find corresponding methods for registerOutputParameter, how we fetch output value?
I tried to callableStatement.getString("q"); it reports errors, but there are no ordinal binding in my source code, does placeholder names doesn't support OUT mode?
Java:
CallableStatement stmt = con.prepareCall("BEGIN if :q is null then :r := 'X'; else :s := 'Y'; end if; END;");
oracle.jdbc.OracleCallableStatement call = (oracle.jdbc.OracleCallableStatement) stmt;
call.registerOutParameter("q", Types.VARCHAR);

</output>by the way, in my below-mentioned SQL 'problematic', when my code uses 'execute immediate' and use placeholder names in IN OUT mode, we always get NULL value (i.e. ':q'), but we can get final value of ':r' when ':r' is OUT mode only; now I get a workaround attached in below-mentioned 'my workaround' block, which split the IN OUT roles to 2 parts, it can work now;
It seems that the difference between 'problematic' and 'my workaround' imply that there are something work unexpectedly when the driver process the placeholder names, because 'my workaround' and ':r in problematic case' make sure the 'execute immediate' returned output values correctly, unluckly driver layer can't get return values.

How do I use a variable within a sql statement

I am trying to use a local variable within an open SQL step but I keep getting an error.
My sql command looks like this "SELECT BoardDetailID FROM BoardDetails WHERE SerialNumber = " + locals.CurrentSerialNo
If I replace the locals.CurrentSerialNo with an actual value such as below the statement works fine.
"SELECT BoardDetailID FROM BoardDetails WHERE SerialNumber = " + " 'ABC001' "
Can someone tell me how to correctly format the statement to use a variable?

Hi,
Thanks for the reply. I have changed the required variable to a string, but with no success. I have reattached my updated sequence file and an image of the error.
When looking at the Data operation step I see that the sql statement is missing everything after the last quotation mark.
Thanks again,
Stuart

Error in using external procedure in PL/SQL Block

After setting up the configuration : Respective entries in
tnsnames.ora
EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
(CONNECT_DATA = (SID = PLSExtProc)(SERVER=DEDICATED))
and listner.ora :
(SID_LIST = (SID_DESC = (GLOBAL_DBNAME = mymachine )(SID_NAME = mysid)) (SID_DESC = (GLOBAL_DBNAME = mymachine )(SID_NAME = myid1))
(SID_DESC = (GLOBAL_DBNAME = mymachine )(SID_NAME = myid2))
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle9i)
(PROGRAM = extproc)
(ENVS="EXTPROC_DLLS = ANY" // Added this entry
(SID_DESC =
(GLOBAL_DBNAME = oracle9i)
(ORACLE_HOME = /oracle9i)
(SID_NAME = oracle9i)
(ENVS="EXTPROC_DLLS= ANY") // Added this entry
Wrote the program as :
===========================================================
#include <stdio.h>
#include<stdlib.h>
void sh(char *command) {
int num;
num = system(command);
===========================================================
Compiled the file (above ) shell.c as :
gcc -c shell.c
Made the library as :
ld -r -o shell.so shell.o
chmod 777shell.so
copied the file to respective Home directories. Made one link to /usr/lib :
which is in LD_LIBRARY_PATH
created the Library as :
CREATE OR REPLACE PROCEDURE shell(command IN char)
AS EXTERNAL
NAME "sh"
LIBRARY shell_lib
LANGUAGE C
PARAMETERS (command string);
So my problem is
when executing the procedure from SQL prompt:
SQL> exec shell('any command');
it throws the following errors :
BEGIN shell('ls'); END;
ERROR at line 1:
ORA-06520: PL/SQL: Error loading external library

ORA-06512: at "CDR_ADMIN.SHELL", line 0

Any help or suggestions would be appreciated
Thanks in advance......
Made one Link to /usr/lib

Nikolai,
I have created a simple process flow which only calls the external process. The script is on the same host as the process flow is deployed to.
I have used two diffent values for the command parameter.
1. I placed the full path of the file in the command parameter and left the script parameter blank:
COMMAND: /edwftp/ppas/scripts/ClearPPAS.sh
PARAMETER_LIST:
SUCCESS_THRESHOLD: 0
SCRIPT:
2.I placed the bash command in the command parameter and the full path in the script parameter.
COMMAND: /usr/bin/sh
PARAMETER_LIST:
SUCCESS_THRESHOLD: 0
SCRIPT: /edwftp/ppas/scripts/ClearPPAS.sh
Both of these appear to work as they print out the statements inside the script but the files that are supposed to be removed still remain.

Running a OS command from PL/sql Block.

I am using UTL_FILE to write data to a text file from within a stored procedure.Before terminating the procedure i would like to run FTP command on the server to copy the file to a different server. Can this be done..... ? Or is this asking for too much..

Search the forums for 'external procedure'. There are examples that have been posted in the past few weeks.

Using launchctl command within a shell script

I have successfully installed two daemons, and I would like to be able to disable and enable them via shell scripts, called by the daemons themselves. Here is my first shell script:
#!/bin/sh
# Testing for presence of a CODEBOY file
if [ -e "/Volumes/CODEBOY/Change.txt" ]
then
osascript '/Users/praxisii/Library/Scripts/MacScript.scpt'
launchctl unload -w '/Users/praxisii/Library/LaunchDaemons/WaitDaemon.plist'
launchctl load -w '/Users/praxisii/Library/LaunchDaemons/RunDaemon.plist'
fi
The daemon works just fine, running the background, calling this script, which is waiting for me to plug in my flash drive (entitled CODEBOY). When the flash is plugged in, the applescript is called, and the first launchctl command is executed, which disables the WaitDaemon. As advertised, the .plist file is re-written with the Disabled key set to true. The next line (which is supposed to enable the RunDaemon) is never executed.
Similarly, if the launchctl line is placed before the osascript line, the applescript is never called. It is as if the shell ignores everything after a single launchctl command, which it will execute.
Any ideas or comments?

Gary:
Thank you for the link to the TN2083. Long, but very informative.
I appreciate all the other comments on this thread. I am an amateur AppleScript/UNIX scripter, and any opportunity to learn more is much appreciated.
I have completely re-worked my original launchd agent system for automatic processing of a file on a flash drive. Here is the .plist file that I now use:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
<key>Label</key>
<string>RunOSAscript</string>
<key>LowPriorityIO</key>
<true/>
<key>Program</key>
<string>/usr/bin/osascript</string>
<key>ProgramArguments</key>
<array>
<string>osascript</string>
<string>/Users/casdvm/Desktop/AutoFlash.scpt</string>
</array>
<key>RunAtLoad</key>
<false/>
<key>ServiceDescription</key>
<string>Runs Applescript directly</string>
<key>StandardOutPath</key>
<string>/Users/casdvm/Desktop/AutoFlashLog.txt</string>
<key>StartInterval</key>
<integer>25</integer>
</dict>
</plist>
The AutoFlash.scpt is an Applescript that simply uses the Finder to check for the presence of a specific file on the flash drive. If it is there, and a certain script property has a value of 2, then it runs the AppleScript that processes the desired file on the flash drive. Once that is done, the script property is set to 0 (to prevent the processing from happening over and over again.). Once the flash drive is removed, the script property is set back to 2 in anticipation of the next time the flash drive is plugged in.
It is much simpler than the two agents I was messing with beforehand. I did indeed discover that this .plist needs to be saved in the LaunchAgents folder of my user Library (thanks again for pointing that out, Gary).
The only problem that I have involves the continuous calling of the Applescript from the launchd agent. As you can see from my .plist file, that AppleScript is called every 25 seconds. I tried setting it up using the OnDemand key, but I kept receiving a re-spooling error of some sort (I don't recall exactly; my notes are sketchy on that phase of testing), so I just decided to have it go every 25 seconds. It really doesn't matter, since I can leave the flash drive plugged in all day anyway, and it only processes the desired file once.
Thanks again for all the commentary and discussion; I am grateful for the assistance.

Using 'NOT IN' Within a SQL Statement

Does anyone know why the following SQL statement does not return any values? The problem is with the SELECT statement within the 'NOT IN' clause. When explicitly typing in the part_ids returned from the select statement, everything works as expected.
Thanks for any help.
SELECT Distinct Part_Id, Trans_Date
     FROM Invctrl
     WHERE Trans_Type = 0
     AND Trans_Date BETWEEN To_Date( '1-Mar-2006 00:00:00', 'dd-mon-yyyy hh24:mi:ss' )
     AND To_Date( '31-Jan-2007 23:59:59', 'dd-mon-yyyy hh24:mi:ss' )
     AND Part_Id NOT IN (SELECT part_Id From InvCtrl WHERE Trans_Date < To_Date( '1-Mar-2006 00:00:00', 'dd-mon-yyyy hh24:mi:ss'))

'NOT IN' should be avoided where ever we can.
Change your query to 'IN' clause as below and it should work.
SELECT DISTINCT part_id, trans_date
           FROM invctrl
          WHERE trans_type = 0
            AND trans_date BETWEEN TO_DATE ('1-Mar-2006 00:00:00',
                                            'dd-mon-yyyy hh24:mi:ss'
                               AND TO_DATE ('31-Jan-2007 23:59:59',
                                            'dd-mon-yyyy hh24:mi:ss'
            AND part_id IN (
                   SELECT part_id
                     FROM invctrl
                    WHERE trans_date BETWEEN TO_DATE ('1-Mar-2006 00:00:00',
                                                      'dd-mon-yyyy hh24:mi:ss'
                                         AND TO_DATE ('31-Jan-2007 23:59:59',
                                                      'dd-mon-yyyy hh24:mi:ss'
                   MINUS
                   SELECT part_id
                     FROM invctrl
                    WHERE trans_date <
                             TO_DATE ('1-Mar-2006 00:00:00',
                                      'dd-mon-yyyy hh24:mi:ss'
