SQL & PL/SQL :: Verify And Perform Validations On Data - Table Partition
Oct 11, 2010
I have a staging table with 70 million rows and nearly 90 columns. We just want to verify and perform some validations on the data and then move this data to final tables. There staging table has a primary key in it.
We are planning to create the final table in following ways.
1. Create n number of final tables.
2. Create n number of final tables with partitions based on the primary key value in staging table.
3. Create single final table with partition based on the primary key value staging table.

I would like to perform a reorganization of the partition table. The table contains 144 partitions and 2038 indexes partitions with that. I would like to ask you to make me understand the best possible way to perform the reorg with cascade options in one attempt.
Also, am not sure how to get the information of the index type is Globally / Local index partition. Is there any document for reference that details about the reorg of partition tables?

We would like to remove the partitions from a particular table. The table in question has 12 partitions. Based on some initial investigation, I've come up with the following options. because the table we going to remove partition will have millions of records so on considering the db downtime we are looking for a alternative way. Is there a better way?
Copy data into another table, drop all partitions, then copy the data back into the original table
Copy data into another table, drop the original table, then rename the new table and rebuild the indexes.

I have a dataguard configuration (physical standby).Database A is the primary database and database B is the standby database (I do not use the broker).Both are Oracle RDBMS 12cR1 EE. The Apply process uses the current log (standby redo logs).On database B, when querying v$managed_ standby;, I get:
ClientProcess process Status ---------- ARCH ARCH CONNECTED ARCH ARCH CONNECTED ARCH ARCH CONNECTED ARCH ARCH CONNECTED RFS ARCH IDLE MRP0 N/A APPLYING_LOG RFS LGWR IDLE
It works fine. Before to perform a switchover,- from database A (current physical database), I get switchover_status = 'TO STANDBY'- from database B (current standby database). I get switchover_status = 'NOT ALLOWED'. What switchover_status = 'NOT ALLOWED' means exactly and how to get further with the switchover?

When I am trying to insert record from tbl_mittal into tbl_temp table. I am facing "ORA-14400: inserted partition key does not map to any partition" error
SQL> insert into tbl_temp select * from tbl_mittal;

it is possible to have two Validations one Page Item. Also I need to execute them one by one. If one is passed then go to the other and validate that one.
Example:P20_FORM_ACTIONP20_REOPENP20_REASON Validation 1: P20_REASON != 0 with condition P20_FORM_ACTION = CLOSEIf Validation 1 is passed then go to Validation 2Validation 2: P20_REASON != 0 with condition P20_REOPEN = YES
If Validation 2 is passed, then submit the form otherwise get error. is possible in Application Express 4.2.2.00.11. I tried to put the validations as described above into my application, but it did not work. Only one Validation was executed.

I am using Oracle 11.2.0.1 Oracle Database.I have a table with 10 Million records and it's a Non Partitioned Table.
1) I would like to partition the table (with partition by range ) without creating new table . I should do it in the existing table itself (not sure DBMS_ REDEFINITION is the only option ) (or) can i use alter table ...?
2) Add one partition which will have data for the unspecified range.

From a list of values from a number column, I need to verify is there any values not satisfying number(3).
Ex- I have a column col1 where we have following values
'qwq'
'12.3'
'1'
'15'
Can I write a query to check the value not satisfying number(3) datatype.Eg the query should return
'qwq'
'12.3'
as the above two will not fit in to number(3) datatype columns
