SQL & PL/SQL :: Execute Several Statements In One Command Of DataAdapter Class?
Jul 18, 2012
When working with SQL Server it's possible to execute several sql statements in one command of the DataAdapter in ADO.Net Now I try the same thing with an oracle database and recieve error ORA-00911: invalid character.
When remove ;character from query it again gives error- ORA-00933: SQL command not properly ended.
My query is like this-
update activity set activityname='Route Survey' where activityid=1;
SELECT * FROM activity where activityid=1

here's my question.
(I'm using PL/SQL Developer with Oracle 10g)
I have an table 'tbcontrol' where for each row I can have one or more sql statements (DML or DDL) in an column.
Example:
task | sql_scripts
1 | create table t1 (c1 number); insert into t1 (c1) values 100;
2 | create table t2 (c2 number); alter table t1 modify c1 not null default 0;
3 | alter table t2 modify c2 not null default 0; alter table t1 add c10 varchar2(10); create table t3 (c3 number not null default 0;
I need to create a procedure where I can pass an task number to execute the sql statements which are in the column 'sql_scripts'. Something like this:
create or replace sp_run_scripts (v_task number)
is
v_scripts varchar2(2000);
begin
select sql_scripts into v_scripts from tbcontrol where task = v_task
execute immediate v_scripts;
end;
But, here I'll have some problems:
- The script will have semicolons (EXECUTE IMMEDIATE doesn't support);
- If I put a begin/end like a PL/SQL script, I can only run DML statements because DDL statements have implicit commit.
- I can't use a cursor for execute each statement at a time because the scripts have multiples-rows. Even if I search for semicolons to 'separate' the scripts in the cursor (using SUBSTR and INSTR functions), I'll have problems with the semicolons between '' (quotations marks).
Now, I admit I'm lost.
Is there another way to make this process work?

i`m trying to use pl/sql function to execute java class. I created 2 tables with around 100 values and java class with simple functionality. I need to create function to loop through my table1 and get with each iteration one value from table and pass that value as parameter to java class.
table1 is something like this:
ID NAME
1 name1
2 name2
3 name3
. .
. .
100 name100
table2 is empty with same columns as table1 ( table2 is for data obtained from java returns ) I created in sql+ java class.
CREATE OR REPLACE AND RESOLVE JAVA SOURCE NAMED "myClass" AS
import java.io.*;
import java.util.*
public class myClass {
public static String fun(String strName)
[code]....
Then i wanna make a pl/sql function for:
1)For i = 1 Obtain first value from table1 (column name) and pass it throught java class then return value and save it in table2 with the same id as id from table1
2) change i=1 to i=2 and do that same
3) end if i=101

I am facing a problem regarding the execute immediate command. I have created a procedure as given below
SQL> set echo on ;
SQL> set serveroutput on;
SQL> declare
2 l_var varchar2(50);
3 sqlstring varchar2(3000);
4 begin
[code].......
In this procedure the execute immediate command shows error ( if i avoid exception).I have tried other syntax too of this command
but it is showing error only.

I have to build a select query but its where conditions will be retrieved from a table. I was told that the execute immediate command can handle it.
lets say i have this:
string_var:= 'select field1, field2, field3
from mytable
where' ' || i.condition_selection || ';'
If the above select resuls in a single row, i could do this:
EXECUTE IMMEDIATE string_var INTO var_field1, var_field2, var_field3;
In my case the select will return multiple rows. How do I proceed ?

I'm on Oracle 11g R1. I've a requirement where user will be putting CSV files on Unix server and I've to create a job which runs periodically to check if any new file is added by user in the folder. If it finds a new file (s), then it needs to identify it and insert its name in an Oracle table. Once file's name is noted, it has to move file from that directory to another one.

I've created a Java class in my Oracle DB that calls a Visual Basic program to convert a XLS file into a CSV file in order to load it into an external table. The problem that I have is that when I call the Visual Basic program from the Java class, nothing happens. I had the same problem with a Python program, and I thought that the problem was from Python, but now with Visual Basic the problem remains, both aren't executed.
The strange thing is that when I call the same Java class outside Oracle, directly from a command line, it executes both Python and Visual Basic programs.
Here is the Java class defined in Oracle:
CREATE OR REPLACE AND COMPILE JAVA SOURCE NAMED "OSCommand" AS
import java.io.*;
public class OSCommand{
public static void Run(){
try
{
[code]....
And here is the procedure that calls the Java class:
create or replace
procedure run_os_command
as language java
name 'OSCommand.Run()';

I'm working with old code that uses dbms_sql.execute to build/execute dynamic sql. In our case, the user can select varying columns(I think up to 20) with different where conditions as needed.
After building the sql, here's an example
WITH ph AS
(SELECT ph.* FROM po_header ph WHERE 1 = 2),
pf AS
(SELECT DISTINCT pf.order_id, pf.fund
FROM po_fau pf, ph
WHERE 1 = 1
AND ph.order_id = pf.order_id
[code]....
Where table records for
po_header = ~567746
po_fau = ~2153570
and PK "order_id" is a NUMBER(10) not null and a snippet of the code looks like
nDDL_Cursor := dbms_sql.open_cursor;
dbms_sql.parse(nDDL_Cursor, sSQLStr, 2);
FOR x IN 1 .. nCols LOOP
sCols(x) := '';
dbms_sql.define_column(nDDL_Cursor, x, sCols(x), 100);
END LOOP;
nError := dbms_sql.execute(nDDL_cursor);
why when the "execute" statement is fired off the elapsed time takes ~4.5 seconds but If I change "1 = 1" above to "1 = 2" it takes ~.2 seconds. If I run the above query interactively it takes ~.2 seconds. Shouldn't the above query when joining
ph.order_id = pf.order_id
return zero rows back instantly or does the "dbms_sql_execute" do some other type of parsing internally that takes cpu time.

I'm modifying a package which contains a function with different parameters (say cno, gno, pname etc) need to be passed though it and that function is called by the cursor later in the program. I need to create a cursor (select statement) for every class (a program set)...i.e. multiple select statements for a program set with different values. The parameters needed to be passed correspond to same columns in different tables...so do i have to refer those tables everytime i'm passing the parameters using a select statement? The Program accepts the parameters as an array (list of parameters) and returns a cursor and the program handles one program set (class) at a time. That parameter list will be in a loop..i.e. it will be repeated for every certain combination (say cno - pname combination). So ... How should i proceed and create a select statement with different parameters declared in the function of type string making it dynamic and returning them using ref cursor?

how can I download some java classes from database? Everything I know is only the name of some java class that is used in one PL/SQL procedure (CREATE OR REPLACE PROCEDURE ..... AS LANGUAGE JAVA).

I need to add one validation in one form. The form is not getting run locally because of some imported java classes which was already there. From application server it works fine. When i run locally it gives ORA_JAVA.EXCEPTION_THROWN. Actually some trigger calls a procedure from this imported java class. Some path is specified in JNI.NEW_OBJECT(). That patg may not be in local system. If those files are included in our oracle home directory

I need to invoke a JavaMail code from oracle server. Conditions are :
On insertion of a row in a table a TRIGGER is to be run. This trigger would invoke a java code, that shoots an email, with desired credentials and login.
The code to send email, is based on JavaMail API, and is compiled on JVM version, 1.6.
The javaMail code can be loaded in oracle server using:
loadjava -user scott@TESTDB SendMailSSL.class
Another code doscmd.class is written and loaded in oracle, that is compiled in java 1.5. It is intended to call the SendMailSSL.class
import java.util.Properties;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
[code].....
Is there a way to invoke SendMailSSL.class, without upgrading the oracle Java version

xxx VARCHAR2(25);
value ORA_JAVA.JOBJECT;

I am getting an error saying the object type is wrong .... I would like to know how to assign a hardcoded value to the JOBJECT just to test before I continue.

Our system stores images on the unix filesystem. We scan full page images.
Our image specs are:
black and white: tiff, group4 compression, 300dpi. so files are about 40-80k compressed
photograpshs/gray scale: jpeg/jpeg compression 256 gray scale. Some images can be 2megs...but most of them are about 400-700k
We build a demo with forms10G/application server 1 year ago and performance was really bad. Took about 10-15 seconds to generate a report with 1 image of it...compared to about 1-2 secs using forms 6i. We just installed weblogic 11G (10.3.5) with forms 11gr2. I'm guessing performance will still be an issue but we will still be testing it.
Our users currently use nfs to access images on the unix server. So that would not changed.
- read_image from filesystem (c: unc path //server/images/.../1.jpeg)
- zoom in, zoom out (having vertical/hori scroll bars to move around...or best would be panning)
- save_image on filesystem
- fit to window/cancas
- always keeping aspect ratio
nice to have options, but not needed at this time
- save in blobs
- editing capabilities (mostly just select an area to delete, like black borders...some speckles here and there)

How to Pick / Extract the java class files from the database.? We have not maintained the latest codes in the oracle application server where java class code is residing.
All the Java Classes are available only in database. So we need to pick the latest java class code from production environment. In TOAD we tried but all class objects are listing at the left side but we are unable to take the code. So how can we take the latest codes(java classes) from the Production Database as a backup.

Most of my day to day work involves the support of DB2 on AIX and z/OS. I support the database infrastructure for one business system that runs on the Oracle RDBMS. The application is Oracle Transportation Management. The non-production environments don't get much traffic. If I sign into the TEST or DEV Enterprise Manager DB Control screen, the following warning is almost always listed on the main page:
Metrics "Database Time Spent Waiting (%)" is at 44.00384 for event class "Concurrency"
Enterprise Manager reports that this metric is continuously fluctuating above and below the warning threshold of 30% of db time when the environment is idle.To investigate(and I am no oracle expert, far from it), I ran the following:
SELECT * FROM v$session_event
WHERE WAIT_CLASS='Concurrency'
ORDER BY TOTAL_WAITS DESC;
By far, the top two entries in the result are the following:
SIDEVENTTOTAL_WAITSTIME_WAITEDAVERAGE_WAITMAX_WAIT
124os thread startup12041423733.5218
359os thread startup150653433.5521
[code]...
Does this indicate a possible problem with the operating system?
