I have a strange case here. I created a View in AS/400. I need to have view not join logical because I need to do a UNION ALL. The view is created and I went to IFS and granted permissions ALL. But when I open Crystal Reports, make the connection to iSeries, and go to that library of the View, it is not showing, so I cannot use.
Is there anything else I need to do?
I just tried something else. this is the view:
CREATE VIEW MKLIB/BEMPLOCM AS
((SELECT LMRIDC, LMCOM#, LMWHS#, LMLOC1, LMLOC2, LMLOC3, LMLTPC, LMLCT1
FROM
((SELECT LMRIDC, LMCOM#, LMWHS#, LMLOC1, LMLOC2, LMLOC3, LMLTPC, LMLCT1
FROM ASTDTA/ICLOCMLM WHERE LMLTPC IN ('PCK', 'PAL', 'RAK')) t1
EXCEPTION JOIN
(SELECT * FROM ASTDTA/ICBALMIE) t2
ON LMLOC1=IELOC1 AND LMLOC2=IELOC2 AND LMLOC3=IELOC3 )
EXCEPTION JOIN
(SELECT * FROM ASTDTA/ICBLDTIR) t3
ON LMLOC1=IRLOC1 AND LMLOC2=IRLOC2 AND LMLOC3=IRLOC3 ))
Now in Crystal reports there is also COMMAND to use to get your data, there you can make the same query but although I want it on the AS/400 for time consideration, the union is needed otherwise i have to run the queries via CL all day. SO I took the above code from the SELECT point, and got this error:
failed to retrieve data from the database. Details: HY000 IBM ISeries
ACCESS ODBC DRIVER (DB2 UDB) sql 5016 - Qualified object name ICLOCMLM
not valid. Vendor code 5016.
Not sure what that means.
Use the GRANT statement to control SQL privileges.
If the view is over regular files you may also have to use the commands GRTOBJAUT, EDTOBJAUT and RVKOBJAUT to modify authorization on those objects.
"It does not list it in the library when I see the tables and views in crystal."
Are you sure that the view is actually in the library you think?
What may have happened is that it may have been created in another library. Try checking in QGPL library, or if you have a library that matches your user profile name, check there.
If the question is 'Why do I get Qualified object name ICLOCMLM not valid.' the answer is probably that you are using *SQL naming and the statement you are running is using *SYSTEM naming. Try changing FROM ASTDTA/ICLOCMLM to FROM ASTDTA.ICLOCMLM and see if the 5016 error goes away.

I cannot seem to find a view which I created in one of my schemas within TOAD. Lets assume I don't know the exact schema in which I've created it, is there any way where I can find all the create statements which have been executed within a period of time, lets say the last days.
Thank you in advance.
If you created the view, just query ALL the views, and order by the date in which it was created.
select * from dba_objects
where object_type = 'VIEW'
order by created desc, last_ddl_time desc
We're hitting DBA_ views to make sure we look at EVERYTHING, not just the things you have PRIVS for. Switch to ALL_ views in case you lack access, and hope you didn't create the view in a schema in which your current logon can't see.
The other way to go is query the views themselves and key in on the table you think you included in the SQL behind the view.
SELECT *
FROM dba_views
WHERE UPPER (text_vc) LIKE '%EMPLOYEES%';
You might be looking for a feature called "SQL Recall" in Toad. Press F8 or View/SQL Recall. It will show you the SQL you ran in the last month or so.
I'm trying to find all (available) SQL history by user in our Oracle 11g database. I've tried using some view such as v$sql_monitor, v$sqlarea, and dba_hist_active_sess_history to try to get usernames, and their executed SQL statements (joined on SID and Serial #) but I'm not having any luck. Our senior DBA and DBE said they've done it before but just told me to look in sqlarea since that has the longest history of SQL held. I'm not having any luck with this. Is this possible to do in Oracle?
Edit: We use SQL Developer. I understand that TOAD may or may not have this feature built-in but I haven't been able to find anything that accomplishes this (other than view current sessions and current SQL) in SQL Developer.
You can try something like that if you have the proper licensing to query dba_hist_active_sess_history, you need a license for the diagnostic pack:
select trunc(hist.sample_time,'DD'),u.name,hist.sql_id,sql.sql_text
from dba_hist_active_sess_history hist,
dba_hist_sqltext sql,
user$ u
where hist.sql_id = sql.sql_id
and hist.user_id = u.user#;
I think the only way to fetch the exact SQL-Executions of a User (i think you mean Session?) is by enabeling Tracing.
I think this article (https://oracle-base.com/articles/misc/sql-trace-10046-trcsess-and-tkprof) gives you a good instruction how it is used.
I am using oracle client 11.2.0
Dll version 4.112.3.0
We have a page in our application where people can give a sql statement and retreive results. basically do an oracle command.executereader
Recently one of my team members gave an update statement as a test and it actually performed an update on a record!!!!
Anyone who has encountered this?
Regards
Sid.
It is a normal (albeit a bit unsettling) behavior. ExecuteReader is expected to execute the sql command provided as CommandText and build a DbDataReader that you use to loop over the results.
If the command doesn't return any row to read is not something that the reader should prevent in any case. And so it is not expected that it checks if your command is really a SELECT statement.
Think for example if you pass a stored procedure name or if you have multiple sql batch to execute. (INSERT followed by a SELECT)
I think that the biggest problem here is the fact that you allow an arbitrary sql command typed by your users to reach the database engine. A very big hole in security. You should, at least, execute some analysis on the query text before submitting the code to the database engine.
I agree with Steve. Your reader will execute any command, and might get a bit confused if it's not a select and doesn't return a result set.
To prevent people from modifying anything, create a new user, grant select only (no update, no delete, no insert) on your tables to that user (grant select on tablename to seconduser). Then, log in as seconduser, and, create synonyms for your tables (create synonym tablename for realowner.tablename). Have your application use the seconduser when connecting to the DB. This should prevent people from "hacking" your site. If you want to be of the safe side, grant no permissions but create session to the second user to prevent him from creating tables, dropping your views and similar stuff (I'd guess your executereader won't allow DDL, but test it to make sure).
I am using Oracle 11g and Toad for Oracle. How can I display execution plan for queries?
In Sql server management studio execution plan can be displayed as graphical format. Is there any functionality/tool like that on Toad for oracle?
CTRL-E
Make sure you've ended the query with a semi-colon (and the query above)
Edit:
You need to set-up the TOAD plan table for use. If you think it's already setup on your DB then you may just need to be granted access. Alternatively in my slightly older version of TOAD it's under:
Database --> Administer --> Server Side Objects Wizard. From here you can create the plan table(s) in a schema that you choose.
You should create the PLAN_TABLE using a script provided by Oracle
which is named UTLXPLAN.SQL and is located in one of the installation folders
on the database server.
Then, you should use the EXPLAIN PLAN statement for generating a plan for a SQL statement, like this:
EXPLAIN PLAN SET STATEMENT_ID = 'your_identifier_for_this_plan'
FOR
... your statement ... ;
Then, you can use either a select from PLAN_TABLE (usually using a hierarchical query) or the DBMS_XPLAN.DISPLAY_PLAN procedure to display the plan.
In the same folder where the UTLXPLAN.SQL file is located, there usually exist
examples of using this procedure.
Also, in SQL*PLUS you can use the SET AUTOTRACE feature.
For TOAD FOR ORACLE
this helped me How do I view the Explain Plan in Oracle Sql developer?, I just write what they did in sql developer and wrote in the toad editor and then execute.
Example
explain plan for select field1, field2 from TABLE_NAME;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);
Check that all queries end with a semicolon, put the cursor on the query you want to analyze and hit CTRL-E.
The first time you could get a popup that asks for the name of the plan table, it suggests TOAD_PLAN_TABLE but it's better to use the standard Oracle table PLAN_TABLE that should be already available. So enter PLAN_TABLE in place of TOAD_PLAN_TABLE (do not specify a schema) and hit OK. You should get a message saying that the object already exists: hit OK again to acknowledge it. Now try CTRL-E again and you'll get the explain plan.
To view/change the currently configured plan table name go to menu "View / Toad Options / Oracle General".
I have the linked server set up in SQL Server 2008. But I could not run any query against the linked server.
I tried to run this simple command but it's not working
SELECT * FROM MYSERVER..ALANH.TEMP_UPDATE1
This is the error I got when I run the above command.
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "OraOLEDB.Oracle" for linked server "MYSERVER" reported an error. The provider did not give any information about the error.
Msg 7312, Level 16, State 1, Line 1
Invalid use of schema or catalog for OLE DB provider "OraOLEDB.Oracle" for linked server "MYSERVER". A four-part name was supplied, but the provider does not expose the necessary interfaces to use a catalog or schema.
Could anyone help me to connect to the OracleLinkedServer? Thanks very much.
you can be that way too:
**SELECT * FROM OPENQUERY(MYSERVER, 'SELECT * FROM ALANH.TEMP_UPDATE1')**
You can write the query like this:
select * FROM [MYSERVER]..[ALANH].[TEMP_UPDATE1]
Important: In this case, the fully qualified table name must be written in upper case.
You might try the fix from this article.
Also, this could be a problem with naming. From an MS KB article
If you receive these error messages, a table may be missing in the
Oracle schema or you may not have permissions on that table. Verify
that the schema name has been typed by using uppercase. The
alphabetical case of the table and of the columns should be as
specified in the Oracle system tables.
On the Oracle side, a table or a column that is created without double
quotation marks is stored in uppercase. If the table or the column is
enclosed in double quotation marks, the table or the column is stored
as is.
First make sure the tnsping utility works from client server, then use the below string in linked server database source setup
host[:port]/service_name
Check this link for more details :
http://www.oracledistilled.com/oracle-database/oracle-net/using-easy-connect-ezconnect-naming-method-to-connect-to-oracle-databases/
Try something like this:
SELECT * FROM ALL_TABLES#"SOME.SERVER.NAME";
In this case I'm selecting ALL_TABLES from a linked server called SOME.SERVER.NAME.
Richard's post above was critical.
I am using v12 ODP.NET odbc drivers and had to ensure that "Zero Level Only" was NOT checked and that the names supplied for table and schema were the correct case. All of the schemas and tables I access are uppercase only.
Use the query below to determine what the correct table name is, though you will have to supply the schema name in the correct case for the query to work. Try all uppercase, try all lowercase, try mixed case, or better yet get the actual name from the dba (I've heard that only table/schema names that are "" quoted will be allowed mixed case, otherwise in oracle it's all uppercase.)
