oracle sql developer first time user - sql

I am new to plsql and trying to use oracle sql developer, I try to run a simple procedure with dbms output line and i get the following error,
ora-00904
, the code is
create or replace PROCEDURE proc_101 IS
v_string_tx VARCHAR2(256) := 'Hello World';
BEGIN
dbms_output.put_line(v_string_tx);
END;
whether i click the run(green colour) or debug(red colour) i get the same error.
You can see from the above code, procedure doesn't access any objects but still i get the same error.

Your procedure is fine. You may not have permissions to be able to Create a Procedure. If this is the case test your procedure/code without actually Creating it in the Database first. For example, when I'm testing code in my Production database my oracle user cannot Create Procedures, Packages, Tables etc... And so I test my Procedures within my Own PL/SQL Blocks. When the code is good to go I can get a database administrator to Create the Procedures and/or Packages for me.
The below screenshot is code that simply tests the Procedure:
The below screenshot is code that does much more and tests the Procedure from within a PL/SQL Block
For more advanced situations this allows you to do so much more as you can create all sorts of Procedures/Functions and/or Cursors and test them immediately without needing to CREATE these objects in your Oracle Database.

I'd say that there's some other code in the worksheet which raises that error, not just the CREATE PROCEDURE you posted. For example, something like this SQL*Plus example (just to show what's going on - you'd get the same result in SQL Developer):
SQL> select pixie from dual;
select pixie from dual
*
ERROR at line 1:
ORA-00904: "PIXIE": invalid identifier
SQL>
SQL> create or replace PROCEDURE proc_101 IS
2 v_string_tx VARCHAR2(256) := 'Hello World';
3 BEGIN
4 dbms_output.put_line(v_string_tx);
5 END;
6 /
Procedure created.
SQL>
See? The first part raised ORA-00904 as there's no PIXIE column in DUAL, while the procedure is created correctly.
So - remove code which fails and everything should be OK.

Check with your DBA to make sure the dbms_output package has been installed on your database, and that you have permissions on it.

What have i gotten wrong for this stored procedure not to execute?

Here is the stored procedure and how I created it
CREATE OR REPLACE STORED PROCEDURE SimpleSelect()
AS
BEGIN
SELECT * FROM Permissions
END;
/
CALL SimpleSelect();
When creating the procedure I get the error
"Success with some compilation errors"
and when running the CALL command I get that the SQL command not properly ended.
It is important to know which database do you use. Some of this advice's will come in handy in many databases but some will not...
Do you have a table called Permissions already created ? If not, create it.
Please put a ; after the SELECT statement. Like this:
SELECT * FROM Permissions;
In MySQL this will not return error:
CREATE PROCEDURE SimpleSelect()
BEGIN
SELECT * FROM Permissions;
END;
/
When you fix your procedure the call command will work just fine...
Cheers!
Here is the DEMO

PL/SQL: Having trouble creating procedure

I'm having issues creating a simple procedure in oracle 10g
All I'm trying to do is this procedure:
create procedure greetings
is
begin
dbms_output.put_line('Hello');
end;
I type this into the prompt:
#proc1.sql
and I get only this:
6
and I'm unable to get back to the prompt again without ctrl+c. I know it's ghetto but I'm using SSH if that helps solve the problem.
You need a / on a line by itself after the final end; so sqlplus will know it's time to execute. (sqlplus somehow fails to know how to parse the language which is its sole purpose for existing, so it doesn't know that the last end; you entered is the one that terminates the create command.)

oracle - run stored procedure from script

I've a script that I am using to build/drop tables and basically setting up the entire schema.
After googling, I still can't figure out how to run a stored procedure.
The script is a .txt file, and I run it using Apex SQL Oracle.
If I write only this line in a script:
execute procedurename(1); --where 1 is paramter.
You have requested to run a script that does not contain any runnable
statements.
SQL>create or replace procedure procedurename(p_num number)
as
begin
null;
end;
/
Procedure created.
SQL>execute procedurename(1);
PL/SQL procedure successfully completed.
everything seems ok on SQLPLUS with oracle 11.
so it must be an apex thing.
Since execute is a sqlplus statement ,try calling the procedure using begin-end PLSQL block in Apex SQL
BEGIN
procedurename(1);
END;
/
save this in a file proc_call.sql and then call it in your script like
#C:\proc_call.sql
where C: is the sample path

ORA:00900 Invalid sql statement

i created a procedure with 32 in argument,it sucessfully created.but when i am executing this in back end oracle the errror came ORA:00900 Invalid sql statement
Use:
SQL> alter procedure [your procedure name here] compile;
SQL> show errors
...to be able to diagnose the issue from the resulting error output.
Also look at view USER_ERRORS.
Sometimes, show errors does not show anything when in fact there are errors. Especially after alter compile.
Finally, re-compile in TOAD or SQL Developer and you can easily navigate to the error.
In Oracle SQL Developer you should execute it this way:
BEGIN
YOUR_PROCEDURE(PARAM1, PARAM2);
END;
If you use EXECUTE or EXEC (which work in SqlPlus) you get the ORA-00900 error.

ORACLE Batching DDL statements within a Execute Immediate

I'm trying to run multiple ddl statements within one Execute Immediate statement.
i thought this would be pretty straight forward but it seems i'm mistaken.
The idea is this:
declare v_cnt number;
begin
select count(*) into v_cnt from all_tables where table_name='TABLE1' and owner = 'AMS';
if v_cnt = 0 then
execute immediate 'CREATE TABLE TABLE1(VALUE VARCHAR2(50) NOT NULL) ALTER TABLE TABLE1 ADD (MYVAL2 NVARCHAR2(10))';
end if;
end;
however this results in an error
ORA-00911: invalid character
ORA-06512: at line 10
Each of the statements within the batch run fine if i execute them by themselves. and if i take this statement and execute it, it will run fine (with the ; between the 2 statements). If i remove the ; between statements i get a different error about invalid option
the plan is that i'll be able to build a table, export the table schema for this table including all it's alter statements, and then run the batch against another system as part of an install/update process.
So, how do i batch these DDL statements within a single execute immediate? Or is there a better way to do what i'm needing?
I'm a bit of a Oracle newb, i must admit. Thank you all for your patience.
The semicolon is not part of Oracle's SQL syntax. SQL*Plus and other client side tools use semicolon to signal the end of a SQL Statement, but the server doesn't see it.
We can force SQL*Plus to pass the semicolon to the DB:
SQL> set sqlterminator off
SQL> select * from user_tables;
2 /
select * from user_tables;
*
ERROR at line 1:
ORA-00911: invalid character
If i take this statement and execute it, it will run fine (with the ; between the 2 statements) The client tool you are using, breaks it into two calls to the DB.
So, I don't think it is possible to pass multiple statements inside an execute immediate.
I suppose one could call execute immediate with a string containing an anonymous PL/SQL block, with individual calls to execute immediate inside it ... and I don't know what the point of doing that would be. ;)
Why do you need a single EXECUTE IMMEDIATE call? Surely just do it as 2 calls?
Bear in mind that each DDL statement contains an implicit COMMIT, so there's no concurency benefit to doing it as a single call.
Also, why not just set up the table correctly in the first call? You could do...
CREATE TABLE TABLE1(VALUE VARCHAR2(50) NOT NULL, MYVAL2 NVARCHAR2(10))
...instead of needing 2 calls.
Also, have you looked at DBMS_METADATA... it can generate DDL for objects such as tables for you.
