How can I extract 7 million records from Oracle database to CSV file - oracle-sqldeveloper

I have already tried the export option in the sql developer,it is very time consuming.
I need to know if there is quicker way to extract data to CSV file.

enter image description here
I think you can try with Toad for oracle in DataGrid view then right click and export Data Set, you can start with a million with WHERE ROWNUM < 1000001

Limit number of exported / imported rows in DBeaver

is there a way to limit the number of rows while exporting or imported data in DBeaver?
In my case I have a remote DB2 and I need to import SOME rows of a specific table into a local MySQL DB that I have.
Is there a way to do that?
Thanks
Limiting the number of rows being exported only makes sense if the export wizard knows what rows (e.g. order) to export. Therefore it only makes sense to export the resultset of a query, as opposed to export the actual table with a limiting factor.
This is how you can do this in DBeaver:
Issue a query like SELECT * FROM my_table ORDER BY mycolumn LIMIT n.
Replace n with any integer you like obviously. You may also add
DESC after mycolumn, if only the most recent rows make sense to you.
Run the query.
In the pane with the resultset, locate the button
tooltipped "Export result set to fil or another table". It looks
like a tray with an upward arrow. In DBeaver 7.2.2, it is just left
of the split number and cog buttons.
Run that wizard, selecting "SQL" target type (Export to SQL INSERT statements)
Click Next, and configure any other export preferences (you may leave default too).
The file being exported should content you.

How tfileinputexcel works in talend

I'm guessing you didn't check Stop reading on encountering empty rows, and that it's reading empty rows from your excel file.
Please try with checkbox checked.

Exporting table names and columns in Excel with Oracle SQL Developer

How can I export only table names and its columns to an excel sheet from a database using Oracle SQL Developer version 4.
I tried exporting database feature, but it does not allow excel export for Metadata.
Sorry if this is asked in wrong forum
Query what you want eg:
select owner,table_name,column_name
from dba_tab_cols
where owner = 'SCHEMA';
Then right click on the result and choose Eksport.... Choose a format and save.

Excel Export Fail when Number of rows in the Excel sheet exceeded the limit of 65536 rows ssrs

In SSRS 2008 (I use Sql Server BIDS to create reports) how to solve "Excel Export Fail when Number of rows in the Excel sheet exceeded the limit of 65536 rows ssrs" issue
Thanks
Yes, this is a limitation of SSRS through 2008R2.
SSRS 2012, included with SQL server 2012 will remove this limit:

The workaround for 2008R2 and before is to export as .csv
When your results are exceeding 65k rows (and you dont have SSRS2012), create a parent group on the tablix (or table, or list) and in the Group on: field enter the expression below.
Add Page break between each instance of a group
=CInt(Ceiling(RowNumber(nothing)/65000))
I think some Excel Versions can not support more then 65536 rows per se. You might consider to expand the data on several worksheets / tables.
A similar Issue is discussed here:
Is it possible to see more than 65536 rows in Excel 2007?
If your report is simple enough you can export as CSV, then import into Excel.
Export that data to csv file first.
then open a new Excel 2010 blank workbook.
Click file and open the exported csv file.
it will give you a Text Import Wizard prompt.
Continue clicking Next and then Finish.
If there is data that you need to keep as text ensure that in Step 3 of 3 you click Text for each column that you want to keep leading zeros if any.
