expdp + query option to export from several tables with the same condition
HelloWe want to export a subset of data only from databases to another. Both on AIX.
Source/testdatabase 11.2.0.3 (non partitioned tables)
Target productiion 11.2.0.3 database (separate tables)
Tables of same names of columns but diffrenet structures a partitioning index and traget so only want to import content
Each source datbaase hascolumn seq number table and want only to extract the last months of data.
TABLES:table1,table2...
DUMPFILE=dump_dir
CONTENT=data_only
QUERY= table1:"WHERE seq_num >100 "
want to use expdp but not sure how to make sure that all tables have the seq_num WHERE > 100 condition, if let table1: go out and have justQUERY = "WHERE seq_num > 100"this condition would apply to all tables that we want."
I'm assuming that can also use impdp CONTENT = data_only?
Any ideas/thoughts?
Thank you
QUERY = "WHERE seq_num > 100"this condition would apply to all tables that we want."
Yes, it will work for all tables, but ensure that all exported table must include this column.
QUERY
Default: no
Goal
Allows you to filter the data that is exported by specifying a clause of a SQL SELECT statement, which is applied to all tables in the work of export or a specific table.
The query_clause is usually a WHERE clause for the selection of refined lines, but could be any SQL clause. For example, an ORDER BY clause can be used to accelerate a migration from a table in a heap in a table held in index. * If a [schema]. table_name is not provided, the query is applied to (and must be valid for) all tables in the export job.*

Hi everyone, yet once landed upward with a problem.
After trying many things to myself, finally decided to post here...
I created a form in form builder 6i in which clicking on a button, the data gets exported to the excel sheet.
It works very well with a single table. The problem now is that I cannot do the same with 2 tables.
Because the tables have the same number of columns and the columns names.
Here are the 2 tables with column names:
Table-1 (MONTHLY_PART_1) Table-2 (MONTHLY_PART_2) SL_NO SL_NO MODEL MODEL END_DATE END_DATE U-1 U-1 U-2 U-2 U-4 U-4 .......... ........ .......... ........ U-20 U-20 U-25 U-25 Given that the tables have the same column names, I get the following error :
402 error at line 103, column 4
required aliases in the SELECT list of the slider to avoid duplicate column names.
So how to export data to excel that has 2 tables with the same number of columns and the column names?
Should I paste the code? Should I publish this query in 'SQL and PL/SQL ' Forum?
Help me with this please.
Thank you.
Wait a second... is this a kind of House of partitioning? Shouldn't it is a union of two tables instead a join?
see you soon

Several files with the same name.
Cannot publish to Business Catalyst because of a fatal error, where it is said "why do we have several files with the same name? The website and all its contents have not changed in more than a year with the exception of minor changes to the wording so unable to understand what the error is encountered. Are there not better misdiagnosed at one point less for the files in question.
The problem is the result of a mixture of case-sensitive and case-insensitive between how files within the .oam are put into interaction with and what is written in the muse_manifest.xml file during a re - download full compared to an incremental download.
If all .oam packages files are tiny and the original .oam were replaced in Muse with the all new tiny .oams, then you should select Upload: publish all the files in the dialog box Options. From there, forward publication of incremental changes should work without errors.

XOQ-01950: Cube contains several BuildSpecifications with the same name.
Hi all
When executing the option to maintain Cube he throws under question: any clue?
XOQ-01950: the AWCubeOrganization for cube 'NN_OLAP_POC. MARKET_SALES_CUBE"contains several BuildSpecifications with the same name.
Thank you
ExqThis error should show only upward when you create a cube (by importing XML), not when you maintain. So, I'll assume that's what you hear.
If you are importing XML that references an OLAP object that already exists, whereas the new definition replaces the old. The only exception to this rule is the BuildSpecification object. This kind of object is called, but it does not follow these conventions (for reasons of disorder of implementation). If you import the XML code that has a BuildSpecificaiton with the same name as one that already exists, then you will trigger the error you see. Here is a relevant example of XML.
The solution is to remove this section from the XML before importing it.

It is possible to have two tables with the same name in Oracle!
Oracle Version: 10 gr 2
MS Access 2007, I had to use the 'Export' by which I copy a table (and its data) to an Oracle schema via an ODBC connection. Later, I realized that, during the copy of tables with a mix of lower and upper case names, the table does not copied (exported). But MS Access will give you the message that table obtained export successfully.
MS-Access mess around Oracle data dictionary.
When you issue
You will see the names of the tables. But when you try to DESCRIBE or SELECT this table, you willSQL>select * from tab; TNAME TABTYPE CLUSTERID ------------------------------ ------- ---------- AMStates TABLE Version TABLE
You can even create another table with the same name in the schemaSQL>desc Version ERROR: ORA-04043: object Version does not exist
Why this is happening and how can I bring these items 'non-existent '?SQL>create table VERSION (X NUMBER); Table created.
Hello
Use
SQL > desc 'Version '.
Or
SQL > select * from 'Version '.
Or
SQL > drop table 'Version '.

Return of the mistake of MUSE: why do we not have several files with the same name?
Well - I thought I had all this worked and fixed, but I met the download error 'Why do we have several files with the same name' once again. (I downloaded all the files several times today in order to 1) works the way it worked the last time and 2) get an OAM file that is not loading for some reason any load again and the download takes about an hour to transfer all the files manually.
To recap:
(1) an option "Upload only modified files" returns the 'Muse has encountered an error and closes. Why do we have several files with the same name? "error just as before.
(2) a full download will work but takes forever and is NOT a substitution for work changed files option.
Please advise with possible solutions!

Is it possible to have two .oam different files in different folders on your computer where the .oam files have the same name? I'm theorizing that there may be a bug in the treatment to ensure the folder created for a .oam placed on the server receives a unique name, particularly in the case of a partial update of the site on the server.
Please send us the .muse file and all the files in .oam related to [email protected] along with a link to this topic for the context so we can attempt to reproduce this error and isolate the root cause. If files are larger than 20 MB, you'll need to use a service such as Adobe send & Track, Dropbox, creative cloud, WeTransfer, etc. file sharing. Thank you.

Drop a large number of tables with the same prefix
Hello
can you help me to make a script to move all the tables with the same prefix = TEST_LINK_?
Thank you very much.
CrystalHi crystal,
Here's something to start. It does not all FK constraints on those tables and assumes that the executor is the owner.
declare pstmt constant varchar2(255) := 'drop table :t purge'; vstmt varchar2(255); begin for rec in (select table_name from user_tables where table_name like 'TEST_LINK\_%' escape '\') loop vstmt := replace(pstmt, ':t', rec.table_name); dbms_output.put_line(vstmt || ';'); -- execute immediate vstmt; end loop; end; /

Can I have several structures with the same case of event event?
Hello
I do an application which reproduces the front of the power supply HP6675A. To do this, I did a machine to States with different States
(initialize, measures, voltage, current, ocp, ov, store, recall, etc.). In each State, should have a structure of the event that attracts the events of the buttons, as for example: If the current state is the voltage mode and the current button is pressed the next State will be the current mode. For this purpose in each State of the state machine should be the same structure of event with the same events.
My problem is that the Vi does not work properly when I have several structures with the same case of event event. There are some possibly to do and how? Or is impossible to have several events? I read a few posts, but I can't find solutions.
Any help is appreciated.
Thank you very much.
In general, you should have 1 structure of the event in your VI. In your state machine, the structure of the event should be in "pending" status So you will probably start in the State of the initialization and then spend idling. Then, the user presses the present button. If your state machine should then, go to the current state and then return to Idle.
