I'm trying to check if table exists and if not, then I want to create it. But I'm still getting this error:
Error report -
ORA-06550: řádka 30, sloupec 28:
PL/SQL: ORA-00942: tabulka nebo pohled neexistuje
ORA-06550: řádka 30, sloupec 3:
PL/SQL: SQL Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
My code is:
SELECT COUNT(*) into cnt FROM dba_tables WHERE owner = 'CENTRUMADMIN' and table_name = 'AUD$_BACKUP';
DBMS_OUTPUT.PUT_LINE(cnt);
IF (cnt <= 0) THEN
EXECUTE IMMEDIATE 'CREATE TABLE CENTRUMADMIN.AUD$_BACKUP AS select * from SYS.AUD$ where 1=2';
DBMS_OUTPUT.PUT_LINE('Vytvorena tabulka AUD$_BACKUP ve shematu CENTRUMADMIN:');
END IF;
This code is inside my procedure for cleaning audit trail.
Can anyone pls help? Thanks in advance!
As I read in your comments you said you get the error only when the table AUD$_BACKUP does not exist.
which means you get you error here:
EXECUTE IMMEDIATE 'CREATE TABLE CENTRUMADMIN.AUD$_BACKUP AS select * from SYS.AUD$ where 1=2';
I guess you just dont have permissions for sys.AUD$ in you schema.
please notice that PL/SQL code can use role privileges. which means, even if you have "dba" role on your schema, it wont work. so you should run the following grant command:
Alter user myuser select on sys.AUD$
good luck.

I am trying to read the code of a 'view' previously created by someone else ,
when i execute this line of code
EXEC sp_helptext [view name]
i get the following error
Msg 15197, Level 16, State 1, Procedure sp_helptext, Line 110
There is no text for object '_RGEN_ITEMVENEX'.
any idea of how to solve this error ?
you should try to grant VIEW DEFINITION to the desired schema's contained in the database to this role.
Refer to this : https://learn.microsoft.com/fr-fr/sql/t-sql/statements/grant-database-permissions-transact-sql?view=sql-server-2017
When I execute a stroed procedure it works. But specifically when I run the select statement I get the following error
Synonym 'syn.Syn_NEO_DB_tGradeAliases' refers to an invalid object.
SELECT
aa.CompanyId [LegCompanyId],
aa.ProductId AS [LegGradeId],
aa.GradeAliasId [LegGradeAliasId],
aa.ProductName AS [LobGradeText],
aa.[Alias] [GradeAlias],
aa.PhraseKey [PhraseKey],
GETUTCDATE() AS 'TimeStamp'
FROM syn.Syn_AAA aa
I haven't done any database change/permission change.
How can I overcome this?
I ran following query and it shows the base_object_name correctly linked to my table.
SELECT * FROM sys.synonyms WHERE name = 'Syn_AAA'
I overcame by replacing synonym with [LINKED_SERVER].[DB_NAME].[SCHEMA_NAME].[OBJECT_NAME].
I am trying to use the oracle SQL access advisor utility.
For recommendation on performance tuning and partitioning of tables.
But when i try to use it gives me no results and says there are no result for the task.
I am trying below code to generate the recommendation this is an example from SCOTT schema which also giving me same error
declare
v_sql varchar2(2000) := 'select * from emp where empno in (7369,7499)';
v_tuning_task varchar2(200) := 'tune_task_advisor_view7';

begin
dbms_advisor.quick_tune ( dbms_advisor.sqlaccess_advisor , v_tuning_task, v_sql );

dbms_advisor.set_task_parameter(v_tuning_task, 'ANALYSIS_SCOPE', 'ALL');
dbms_advisor.set_task_parameter(v_tuning_task, 'STORAGE_CHANGE', '10000000');
dbms_advisor.set_task_parameter ( v_tuning_task, 'MODE', 'COMPREHENSIVE');
dbms_output.put_line ('Quick Tune Completed');
end;
SELECT DBMS_ADVISOR.get_task_script ('tune_task_advisor_view7') AS script FROM dual;
The Error --
SELECT DBMS_ADVISOR.get_task_script ('tune_task_advisor_view7') AS script FROM dual
Error report -

Is there any parameter which i missed to define here.
For RESET_TASK if i do not rest_task then it gives me error for it also so i have used it here.
Thanks in advance
When I get this error, this typically means that the DBMS_ADVISOR does not have any advise for the profile based on its diagnostic so it doesn't return a report. I typically don't try to produce a ADDM advisor report, but rather look for all the HASH plans I can find for the query, run an explain plan on those hash values, and then profile the one with the best plan.
I forgot to execute the task !
exec dbms_advisor.execute_task('tune_task_advisor_view7');
and then
SELECT DBMS_ADVISOR.get_task_script ('tune_task_advisor_view7') AS script FROM
dual;
OUTPUT will be

If creating a profile doesn’t work or if the plan does not exist in the cursor cache, check the AWR repository to see if a better plan exists.
If you have an AWR repository with the correct plan, you can rerun the queries above and just use the option to get the hash and sql_id from the AWR repository.
If that doesn't work. THEN I used ADDM (As you did above).
When i am running below query first time its working but after again i am going to run this query i am getting exception

Well, as I understand the author is trying to do it in one sql query. But in Oracle you can not use IF statement in simple sql. Moreover, even if you use PL/SQL the DDL statements are not allowed to be directly invoked from PL/SQL code, so you should use dynamic SQL. I think, the following script will do what you want:
DECLARE
rec NUMBER;
BEGIN
SELECT COUNT(*) INTO rec FROM all_tables WHERE table_name='DEFAULTTABLE';
IF (rec=0) THEN
EXECUTE IMMEDIATE 'CREATE TABLE DefaultTable(
Code INT NOT NULL,
Code1 INT NOT NULL,
ResultCode INT NOT NULL,
CONSTRAINT DefaultTable_PK
PRIMARY KEY(Code,Code1,ResultCode)
)';
ELSE
dbms_output.put_line('DefaultTable Already Exist');
END IF;
END;
Please, note that in order to see the messages printed via dbms_output, you should execute:
SET SERVEROUTPUT ON;
If you read the error message you will notice it says:
ORA-00955: name is already used by an existing object
This means you are trying to create a table that already exists. That explains why it runs the first time and not any more after that.
Check the entries in all_tables and you will find that Oracle creates tablenames in uppercase. So check for 'DEFAULTTABLE'.
Hi I am using postgresql 8.1.22, I am trying to setup postgresql auditing using the following function.

But if you observe in the above function current_query() is not coming with the mentioned language plpgsql. It throws some error. When I googled I found that in order to use current_query() function PL/CTL language must be installed. I tried to install as mentioned below. It throws an error. So kindly help me how to install PL/CTL language into my database so that current_query() function should work
-bash-3.2$ createlang -d dbname pltcl
createlang: language installation failed: ERROR: could not access file "$libdir/pltcl": No such file or directory
Okay as you suggested I created that current_query() function,but this time I got some thing like this , What i did is ,
CREATE TABLE phonebook(phone VARCHAR(32), firstname VARCHAR(32), lastname VARCHAR(32), address VARCHAR(64));
CREATE TRIGGER phonebook_auditt AFTER INSERT OR UPDATE OR DELETE ON phonebook
FOR EACH ROW EXECUTE PROCEDURE audit.if_modified_func();
INSERT INTO phonebook(phone, firstname, lastname, address) VALUES('9966888200', 'John', 'Doe', 'North America');
for testing the function i created a table named phonebook and created a trigger so that the function mentioned above audit.if_modified_func() will be executed after any insert or update or delete.the row is getting inserted but I am getting a error reg the audit.if_modified_func() function .the error is as follows
WARNING: [AUDIT.IF_MODIFIED_FUNC] - UDF ERROR [OTHER] - SQLSTATE: 42703, SQLERRM: column "*" not found in data type phonebook
Query returned successfully: 1 rows affected, 10 ms execution time.
Kindly tell me what can i do to get rid of the above error.
Not sure where you found the information about current_query and pltcl. These are unrelated. The reason why you can't find pltcl is simply because you're using too old PostgreSQL. current_query() has been added to Pg in version 8.4.
Is there any particular reason why you're using such old version? It is no longer supported, and it lacks almost 8 years of added features!
If you have to use 8.1, you might want to define:
create function current_query() returns text as '
select current_query from pg_stat_activity where procpid = pg_backend_pid();
' language sql;
But it is much better idea just to upgrade.
As for edited and added second question - it's very likely that Pg 8.1 cannot use "row.*" construct. Find who wrote the original code with the "dance comments", and ask about it. Perhaps it was meant to work in newer Pgs.
