Unable to Drop table from a corrupted Data Block

while exporting tables i got message data block corrupted 7481. and while i was trying to drop the table, found SQL Recursive Error.
Pls Help me. i am on the way to recreate my database..
Thanks

Is 7481 the block number?. Block corruption can be diagnosed using the CLI (Command Line Interface) dbv (database verify). You can also diagnose it by looking for the corresponding error message in the alert.log.
Trying to recover data from a corrupt block is only possible using rman. Otherwise, the only thing you can do is to mark the block as corrupt using DBMS_REPAIR, rebuild the table and try to rescue data by recapturing it.

when i tried to drop this mview it gives me this error

I have tried to fix the corrupted data blocks by using dbms_repair package, but of no use.
I have marked this block to be skipped by using dbms_repair.skip_block but still unable to drop it.
Please suggest what should I do?
Thanks in advance

You are lucky if only your undesirable MV is affected by theese corrupted blocks. This is an advice to do a complete-super-full-hot-cold-middle backup of ypur database and search for any disk for a "possible replace".

Unable to retrieve tables from this connection

I have been using Dreamweaver for over 5 years. I have been
using an Access database and ASP the entire time. I am using a
Windows 2000 server for the database and web site. I have used
every verson of Dreamweaver since Ultra Dev. When I bought verson 8
and upgraded to 8.0.2, I began getting the following message when I
try to edit or create a recordset.
"Unable to retrieve tables from this connection, click on the
'Define...' button to test this connection."
I don't know what to do. Is this a widespread problem? Is it
a Windows problem? Is it a Dreamweaver problem? Is it a network
problem?
Please HELP!

Did you ever get an answer for this ?
I am having the same issue but using XP professional.

Hi user631592 ;-)
You can't used directly a DDL statment.
But you can use an EXECUTE IMMEDIATE in your process.
SO
BEGIN
EXECUTE IMMEDIATE ' DROP TABLE STATPHI_595730051';
END;

Drop Tables from Excel

This is my code that I want to excecute using ORAOLEDB driver in Excel. It executes fine from Rapid/SQL but it will not run in Excel and I am not finding any docuemntation on much of anything to do with oraOLEDB.

select count(*) into in_Exists from all_tables where UPPER(table_name) = upper(tbl);

My goal for all this is.
To run a main set of quiries to get the data formated the way I want, then for serveral worksheets I will do quries off the main query to get the specific data. So using Temp tables may not always be the way I need to go.
The error when running the Main query is this (I think this may be because it does not return data, but not sure).
"The Query did not run, or the database table could not be opened.
Check the database server or contract your database administrator. Make sure the external database is available and hasn't been moved or reorganized, then try the operation again."Well, that's not much information to go on. :-/
a) Running queries off a main query is tantamount to a query loop and sounds like it'll be slow. If you really can't do it all in a single query then fair enough, but always aim to incorporate everything in a 1 hit query if you can so that all the work is done in the SQL engine, which is the best place for processing data.
b) The fact the "query did not run", I'm guessing is referring to you calling that procedure you've shown us? (If not show us what it is doing at the time). If that procedure is not running you need to determine why not, so perhaps add some debug messages (log them to a table or something with an autonomous transaction procedure) and see how far it gets. It could be something as simple as needing explicitly granted permissions on those tables rather than relying on role based grants. It could also be to do with dependencies, because dropping tables at run time can render other things "invalid", which is why Oracle provides Global Temporary Tables so you don't have to create and drop tables at run time.

Drop tables from USERS tablesapce

Hello,
I am newbie to Oracle
1) I want to DROP all tables we created except from those that begins with QNT letters. I tried
BEGIN
FOR T IN (SELECT TABLE_NAME FROM USER_TABLES)
LOOP
EXECUTE IMMEDIATE ('DROP TABLE MyUserName.' || T.TABLE_NAME);
END LOOP;
END;
but I get error
ORA-00933: SQL command not properly ended
or when changing line 4
EXECUTE IMMEDIATE ('DROP TABLE ' || T.TABLE_NAME);
I get
ORA-00903: Invalid table name
What's the problem? How Can I ignore QNTxxxx tables?
2) In addition, I get error when log in to Oracle Schema Manager (though, I log in successfully to SQL WorkSheet)
MGR-02150: an unrecognized database version was encountered.
why?
The server app is 10g, and my computer client app is 8.0.5
Your help will be appreciated,
Ori

note: I made little change: 'Q' instead of 'QNT'

For example, I have 5 tables, then my procedure should first checks the existence , then drop all those 5 tables from the database. Actually, I have to attach this procedure to report buildeer, so please keep in mind the above mentioned scenario. Your input will be highly appriciated.

Dropping 5 tables each time user hits the report!!! (According to my understanding)
I would like to share my experience. My group developed many complex reports, we used oracle jobs to run the complex queries time to time, according to our business requirements and stored the result in a final table. Just for viewing at front end level, we used a simple select statement.

SET_BLOCK_PROPERTY('QUERY_DATA_SOURCE_NAME') with FROM clause query data block

Two block :
- Block A based on table
- Block B based on FROM clause query
In WHEN-NEW-RECORD-INSTANCE of block A, I perform a SET_BLOCK_PROPERTY('BLOCK_B','QUERY_DATA_SOURCE_NAME','(...)'); and then query block B (... depends on value taken by 'code' column in block A).
At runtime it works till 'code' does not change (query_data_source_name does not change) but when I navigate to a record having a different 'code', it got the folowing message :
41380 - Cannot set the blocks query data source.
Any idea or suggestion ?

Hello all i m trying dynamically change query_data_source_name but its not working.
i did the followings
Forms(10g2) block level:Query_data_source_type
Query_data_source_name:SELECT 1,2,3,4,5 FROM dual;
in control Block:
when_button_press my code is
GO_BLOCK('blk_query');
Clear_Block(No_Validate);
set_block_property('blk_query',query_data_source_name,
'SELECT col1,col2,col3,col4,col5 FROM mytable');
execute_query;
same result:unable to query error.
any one can help me regarding this issue.

Using a second table in a Database Data Block ??

In a Form, I have a Data Block which is a Database Data Block. The Items are associated with columns in a table.
I want the items in this repeating block to show in a different order. To do this, I need to use a second table and say where table1.key = table2.key ....
I keep getting problems at runtime with
ORA-00918: column ambiguously defined
I tried to qualify everywhere a column name is used. When I do show error it shows
SELECT ROWID, ....
And then the "column ambiguously defined".
I do not have an item in my Form for ROWID. Maybe it is automatic. (This form DOES do update).
Is it possible to use two tables in a Data Block like this?
Thanks

If you only need to order the records in the block, why not defining the "ORDER BY" clause in the block's property??
Set the "ORDER BY" clause at design time from the property palette of the block or runtime with column of your choice.
at runtime your can use:
SET_BLOCK_PROPERTY('your_block', ORDER_BY, 'your_column');If you need to join to tables in one block read the [Block Based on Join|http://www.oracle.com/technology/products/forms/pdf/BlockOnAJoin.pdf] Documentation.

Corrupted Data Block

While doing a routine maintenance, I realized that my production database has two bad data block.
select count(*) from v$database_block_corruption;
COUNT(*)
2I tried using blockrecover command in RMAN and quickly realized that we have already deleted the backup set that could have help us restored the corrupted blocks.
Is there a way I could fix the corrupted block without the backup?
Thank you,

Thank you, I will look at this document sometime today.

Unable to truncate table from plsql

i want to collect stats as my query runs.
i cannot do it from plsql
declare
-- Local variables here
i integer;
begin
-- Test statements here
SET AUTOTRACE ON;
truncate table plan_table;
end;how do i do it.

Hi,
TRUNCATE TABLE is not a PL/SQL command; it's a SQL command.
To run a purely SQL command in PL/SQL, use EXECUTE IMMEDIATE.
SET AUTOTRACE isn't a PL/SQL command either; it's a SQL*Plus command, and I don't know of any way to run it except from the SQL*Plus command prompt.
I think this is what you need to do:
SET AUTOTRACE ON;
declare
-- Local variables here
i integer;
begin
-- Test statements here
EXECUTE IMMEDIATE 'truncate table plan_table';
end;
