How to execute PL/SQL and branch in APEX 3.0

I have written an APEX app with the following pages:
1 - Main page with a "start" button that navigates to page 2
2 - Page with a Branch "Branch to function returning a page", which has PL/SQL that returns '3' if successful or '4' if there is an error
3 - Page with HTML to display "Success"
4 - Page with HTML to display "Error"
I wrote this as a very simple test to verify how to implement a button to execute a block of PL/SQL and then go to a results page. So, there is almost nothing to it right now - just the four pages described and a small PL/SQL block that actually will always fail because it SELECTs from a table that does not yet exist. The problem is that when I click the button it goes to page 2 properly (the page displays) but I can't tell if the PL/SQL is executed and it does not leave that page. What am I doing wrong? Any help would REALLY be appreciated!

That's somewhat more complicated. If you create a Page Process (your 'long running process') that fires On Load - After Footer you won't see anything until it's finished.
So you need an AJAX function to kick off an Application Process and call this AJAX function in the OnLoad of the BODY... And yes, you can show a progress bar or something similar then by checking if your AJAX function is finished yet.
If you want to go that way you can search this forum on "AJAX ONLOAD" or something similar (or start a new thread).

How to execute an SQL query present in a string inside an ABAP program?

hello,
How to execute an SQL query present in a string inside an ABAP program

Raut,
You can execute Native SQl statements.
Ex: To use a Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement as follows:
EXEC SQL [PERFORMING <form>].
<Native SQL statement>
ENDEXEC.
There is no period after Native SQL statements. Furthermore, using inverted commas (") or an asterisk (*) at the beginning of a line in a native SQL statement does not introduce a comment as it would in normal ABAP syntax. You need to know whether table and field names are case-sensitive in your chosen database.
In Native SQL statements, the data is transported between the database table and the ABAP program using host variables. These are declared in the ABAP program, and preceded in the Native SQL statement by a colon (:). You can use elementary structures as host variables. Exceptionally, structures in an INTO clause are treated as though all of their fields were listed individually.
If the selection in a Native SQL SELECT statement is a table, you can pass it to ABAP line by line using the PERFORMING addition. The program calls a subroutine <form> for each line read. You can process the data further within the subroutine.
As in Open SQL, after the ENDEXEC statement, SY-DBCNT contains the number of lines processed. In nearly all cases, SY-SUBRC contains the value 0 after the ENDEXEC statement. Cursor operations form an exception: After FETCH, SY-SUBRC is 4 if no more records could be read. This also applies when you read a result set using EXEC SQL PERFORMING.
EXEC SQL PERFORMING loop_output.
SELECT connid, cityfrom, cityto
INTO :wa
FROM spfli
WHERE carrid = :c1
ENDEXEC.

this batch file when eexecuted connects me to sql prompt.
Now i want to execute my backup script bkp.sql automatically when it is connected to sql prompt.
(i tried with these lines in the above batch file...
call bkp.sql---it just opens the bkp.sql file in notepad & displays the script
start bkp.sql---same as call
connect / as sysdba/pwd@[email protected] --- does not work simply remains a the sql prompt.
At 17:00 /Every:w,f "d:\bkp.sql"---does not work simply remains at the sql promt.)
Can any1 let me know what should i write in the batch file that will execute the bkp.sql file automatically after it gets connected to sql prompt. M using oracle 9i.
I'll manage he time through windows utility of scheduling task.. Let me know how to execute the .sql file from a batch file.
Thanks
Tripti

Try
sqlplus "sys/oracletest as sysdba" @bpk.sql
Working locally, and having set the ORACLE_SID, you don't need to specify the SqlNet alias (@testdb).
Remember to put an exit at the end of the bpk.sql script.

How to execute a sql file inside a plsql file?

It's easy to exec a plsql inside a sql. Simply
start my_proc.plsql
exec my_proc;
But how to execute a sql file inside a plsql file?
declare ...
begin
start my_sql.sql?
end;
Thanks.

Doesn't work. Even though @ is different from start in this case but it just doesn't like the way sql and plsql are mixed. For example:
DECLARE n NUMBER := 0;
BEGIN
select COUNT(*) INTO n from user_tab_partitions;
DBMS_OUTPUT.put_line('Number of partitioned tables = ' || to_char(n));
if n = 0 then
DBMS_OUTPUT.put_line('createViewsProcs.sql');
@createViewsProcs.sql
else
DBMS_OUTPUT.put_line('createPartitionViewsProcs.sql');
@createPartitionViewsProcs.sql
end of;
END;
SQL> @postimp.sql
SQL> DECLARE n NUMBER := 0;
2 BEGIN
3 select COUNT(*) INTO n from user_tab_partitions;
4
5 DBMS_OUTPUT.put_line('Number of partitioned tables = ' || to_char(n));
6
7 if n = 0 then
8 DBMS_OUTPUT.put_line('createViewsProcs.sql');
9 @createViewsProcs.sql
9 SET SERVEROUTPUT ON SIZE UNLIMITED;
10 SET TERM ON;

How to execute the *.sql when using occi and vc

help me!
i must to initialize the remote database using the file of sql,
for example:
the file is ss.sql;
and it is
"DECLARE
row integer := 0;
user varchar2(256);
BEGIN
user := '&1';
dbms_java.grant_policy_permission('PUBLIC', 'SYS',
'java.lang.RuntimePermission', 'loadLibrary.*', row);
dbms_java.grant_permission(user, 'SYS:java.lang.RuntimePermission',
'loadLibrary.orawcom10', null);
dbms_java.disable_permission(row);
dbms_java.delete_permission(row);
EXCEPTION
WHEN OTHERS THEN
IF row > 0 THEN
dbms_java.disable_permission(row);
dbms_java.delete_permission(row);
END IF;
RAISE;
END;"
i use the occi statement
Environment * env;
Connection * conn;
Statement * stmt;
env=Environment::createEnvironment(Environment::DefaultEnvironment);
conn=env->createConnect(user_name,pwd,db_name);
string sqlstmt=''BEGIN ss.sql;END";
stmt=conn->createStatement(sqlstmt);
it is wrong
how do i change the sql statement???

Hi,
Instead of having the PL/SQL code as an anonymous block, you can create
a procedure and then execute it through OCCI.
For example:
create or replace procedure my_proc
is
row integer := 0;
user varchar2(256);
begin
--code here...
end;
I assume this code will be in ss.sql. Compile this procedure in
your schema and then form the sqlstmt in OCCI this way:
Statement *stmt = con->createStatement("BEGIN my_proc; END;") ;
Rgds.

How to execute a sql query in VO????

Hi every body.
Can you show me the way to execute a sql query in VO.

How to execute an sql function containing a SELECT query as paramete

Hi
I want to execute this sql query using JDBC methods , but could not be able to find any appropriate method to execute this query.

Java code? You can't execute that query at all since it is invalid. The parameter needs to be a query string NOT a query.
select dbms_xmlgen.getxml('select * from departments') from dual See the DBMS_XMLGEN package in the docs
http://docs.oracle.com/cd/B28359_01/appdev.111/b28419/d_xmlgen.htm#i1013206
>
Converts the results from the SQL query string to XML format, and returns the XML as a temporary CLOB, which must be subsequently freed using the DBMS_LOB.FREETEMPORARY call:
DBMS_XMLGEN.GETXML (
sqlQuery IN VARCHAR2,
dtdOrSchema IN number := NONE)
RETURN CLOB;
>
Then you execute that query like any other query that returns a result set. The result set will consist of one row and one column of CLOB datatype.
See the JDBC Developer's Guide - it has examples of how to execute queries that return result sets.
And this section shows how tow read/write CLOBs

How to execute multiple sql statements in parallel ?

Hi There,
I have 10 stored procedures, each one will take approximately 5 seconds to run individually.
Now I need to combine the results of these 10 stored procedures into single result set.
So I have created one more stored procedure "proc_AllSPs" to get the single result set.
The procedure "proc_AllSPs" is taking one minute to run because all the procedures inside the "proc_AllSPs" are running
one after the other and taking 5 seconds each.
If there is any other way that all the procedures run parallelly, then the procedure "proc_AllSPs" can run in 5 seconds time.
Sorry if I am not being elaborated.
PLease get back to me if any piece of information is needed.
Any kind of help is truly thankful.
Thanks,
