I'm trying to wirte a little log procedure for my database. I create a procedure with this statment:
create procedure prc_wirte_log (
in p_schema varchar(255),
in p_item varchar(255),
in p_message varchar(255)
)
begin
insert into weather.log (`schema`, item, message) values (p_schema, p_item, p_message);
end;
I get the error Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '' at line 7 0.063 sec
Why? The MySQL Workbench means Incomplet Statment: excepting ; after the insert query.
What could I do?
Multistatement procedures (assumed when BEGIN...END is present) require delimiter overrides to prevent the statements they contain from terminating the procedure definition prematurely.
Typically, you need to do something like:
DELIMITER //
CREATE PROCEDURE blah()
BEGIN
statements;
END//
DELIMITER ;
The first example on the documentation here demonstrates this (though the last two on that page seem to repeat your mistake.
If you are using WorkBench or similar tool just right click on StoredProcedures and click Create stored procedure the tool will create default structure like below and you could write your logic and hit on apply. Ensure to use semicolon at the end of the last statement (just before END).
CREATE PROCEDURE `new_procedure` ()
BEGIN
select * from tasks;
END

I am trying to create a stored procedure in oracle 12c database and I am getting error when I am running code to store the procedure.
PLS-00103: Encountered the symbol "CREATE" when expecting one of the
There are multiple stack overflow question already asked on this topic. but they suggest some different syntax. which is deviation from actual oracle documentation. and even those didn't worked for me
I checked for documentation on multiple website including oracle documentation. oracle documetation suggest syntax as following
Oracle STORED PROCEDURE DOCUMENTATION
so I as per the syntax I wrote the following procedure.
CREATE PROCEDURE PDD_PROC_BASE
AS
--DROP TABLE BASE;
CREATE TABLE BASE as
SELECT idno
,DATE
,diff
,SUBSTR(idNO,7,2) AS PRD
,COMPLETED
,CATG
,OP_Number
FROM table1
WHERE = date >= '30-JUN-2018'
AND STATUS = 'G'
END;
and I got the following error.
Procedure PDD_PROC_BASE compiled
Errors: check compiler log
Errors for PROCEDURE AN_5043152.PDD_PROC_BASE:

7/5 PLS-00103: Encountered the symbol "CREATE" when expecting one of the following:

I checked other resources as well but still didn't understood what went wrong.
I even tried code example from Oracle documentation and got similar error.

You cant use directly sql ddl statements in plsql block, you can do the same thing using dynamic sql with the "EXECUTE IMMEDIATE" statement like this:
begin
execute immediate 'create table test_table1 (test_column1 varchar2(40))';--your create table statement here
end;
In Oracle in stored procedures you can use DDL statements only as dynamic SQL, that means as EXECUTE IMMEDIATE 'CREATE TABLE ' ...
Check here, for example: http://www.dba-oracle.com/t_using_ddl_create_index_table_plsql.htm
I'm a SQL Server DBA currently getting up to speed on Oracle. I'm trying to create something very similar to sp_WhoIsActive for SQL Server but for Oracle without reinventing the wheel. Essentially all I'm doing is selecting some values from v$session and inserting them into a table (poor man's ASH/AWR).
It would seem that in Oracle 12.1, there's a bug when querying dictionary views where it can take forever due to bad parsing logic (Bug 22225899 : SLOW PARSE FOR COMPLEX QUERY). The work-around is to set a session parameter:
alter session set "_optimizer_squ_bottomup"=false;
In T-SQL, I could very easily execute a stored procedure in-session and set this variable at runtime. However in Oracle, it wouldn't seem thats the case.
Sample Code:
CREATE OR REPLACE PROCEDURE SP_DB_ACTIVITY
(
v_temp NUMBER :=1
) IS
BEGIN
alter session set "_optimizer_squ_bottomup"=false;
INSERT INTO SY_DB_ACTIVITY
SELECT
<fields>
FROM
v$session;
commit;
When I run this, I get the error:
"PLS-00103: Encountered symbol 'ALTER' when expecting one of the following..."
Right now, the only way I know how to do this is via a utility like SQL Plus that initiates an interactive user session. Can anyone give me some direction as to how Oracle handles this situation? I'd like to bundle this up into a SP or a Package and then call it from Oracle Scheduler.
Hre is a simple example how to execute alter session inside of the procedure:
CREATE PROCEDURE SP_DB_ACTIVITY IS
BEGIN
EXECUTE IMMEDIATE 'alter session set "_optimizer_squ_bottomup"=false';
END;
/
Here is the way you can combine that with your select and insert statement:
CREATE OR REPLACE PROCEDURE SP_DB_ACTIVITY
(v_temp IN number) AS
v_Id NUMBER;
BEGIN
EXECUTE IMMEDIATE 'alter session set "_optimizer_squ_bottomup"=false';
SELECT 1
INTO v_Id
FROM dual;
INSERT INTO SY_DB_ACTIVITY (id) VALUES(v_Id);
END SP_DB_ACTIVITY;
/
Here is a small DEMO where you can see what will procedure do when you call it and how you can call it. Also, in this example you are calling procedure with and IN parameter. So you can use that parameter for something and in the example above is the procedure without any parameters...
You can also, of course, insert into table directly:
CREATE OR REPLACE PROCEDURE SP_DB_ACTIVITY
(v_temp IN number) AS
v_Id NUMBER;
BEGIN
EXECUTE IMMEDIATE 'alter session set "_optimizer_squ_bottomup"=false';
INSERT INTO SY_DB_ACTIVITY(id)
select 1
from dual;
END SP_DB_ACTIVITY;
/
I've created the following procedure
Create or replace procedure abcd
(
tab_name in USER_TABLES.table_name%type
)
is
begin
execute immediate
'select * from'||tab_name;
end abcd;
The procedure gets compiled.
I am trying to get the output using the following
select abcd('Table') from dual ;
I am new to dynamic SQL and this does not seem to work for me. I keep getting the error
[Error] Execution (44: 8): ORA-00904: "ABCD": invalid identifier
Can someone please help ?

You're missing a space before your table name:
create or replace procedure abcd (tab_name in USER_TABLES.table_name%type )
is
begin
execute immediate 'select * from '||tab_name;
end abcd;
This won't work because you're trying to call it as a function, not a procedure:
select abcd('Table') from dual ;
Your second attempt should now work:
exec abcd('Table');
... but will now get a different error. In PL/SQL you have to select into something. In this case you probably want to open a cursor with the dynamic string and do something with the results. Not really sure what your end goal is though.
You should also read up about SQL injection while you learn about dynamic SQL.
you cannot perform a select on a procedure, a function will work only if single record return.
use
begin
abcd();
end;
or use
execute keyword
ALSO use a space after from in query
It will not work.
When you invoke EXECUTE IMMEDIATE the sql statement is send to SQL engine. No results are passed back to the PL/SQL.
Writing "SELECT * FROM a_table" is not that hard and much safer.
I have one create procedure query i m trying to execute it in Oracle Database.Below is the query :
CREATE OR REPLACE PROCEDURE TEST_PROC IS
TYPE TESTTABLE IS TABLE OF a.TEST102%ROWTYPE;
Synatax of the query seems to be fine but when i am executing it is throwing below sql exception.
Encountered the symbol "end-of-file" when expecting one of the following:
. ( # % ; not null range alter character
Trying to find out the issue trying all possible ways from past two days but i did not get any idea wheres the issue is.Can anyone please suggest what is wrong with the query???? Would be great if some one can help me out here.
Procedures must have BEGIN..END block.
Here is a procedure that does not do anything.
CREATE OR REPLACE PROCEDURE TEST_PROC
IS
TYPE TESTTABLE IS TABLE OF dual%ROWTYPE;
BEGIN
NULL;
END;
the following will work:
CREATE TABLE TEST102(id number);
CREATE OR REPLACE PROCEDURE TEST_PROC IS
TYPE TESTTABLE IS TABLE OF TEST102%ROWTYPE;
BEGIN
NULL; -- insert procedure body here
END;
Can i use insert into tables in a procedure (on oracle) ? example:
procedure my_procedure (aa1 number ,aa2 number ) is
begin
insert into lam_table values(aa1,aa2,null) ;(*ofcourse depending on the tables )
...
...
end ;
** note
i tried it and it worked but there were a message in the bottom that said (successfully compiled not modified )
Yes, you can. Just be aware of the difference between creating the procedure and executing it. Once the procedure is created, you can execute it with:
begin
my_procedure(aa1, aa2);
end;
where aa1 and aa2 are the supplied values for the args.
Just as dpbradley says.
Also, any insert performed by your insert statement will only be visible in that session unless you do a
commit;
