Install Oraoledb Oracle Provider on this page. You cannot import a dump file from PL/SQL developer. Instead, you have to do it from the command line. Furthermore, you need access to the file system of the database server since you have to put the dump file in a directory directly accessible by Oracle.

In SQL Developer, from the top menu choose Tools >Data Export. This launches the Data Export wizard. So that is export. It creatres export.sql file. Now how to do. This video will show you how you can use PL/SQL Developer from Allround Automations to perform a text import, in my case a.CSV file into a simple table.

The tool to import the dump file is called impdp (in earlier version, it was imp). My experience is that you need information how the dump file was created so you can use the correct import mode: • Is it a dump of the full database or just a single user/schema? • Does it include the table schema or just the table data? • What's the schema/user name if a single schema was exported?

You'll find more information about impdp on this.

This question comes up about as frequently as the ‘how do I export data to XLS?’ question. It’s pretty simple once you’ve ran through the process a few times. But you may be here because you’ve never ran through the process before. This post will step you from beginning to end. You should be prepared to import data to an existing table from Excel with confidence after reading this post.. Warning: This post has a LOT of pictures.

For our example I’ll be using HR.EMPLOYEES to build the XLS file. I have created a blank copy of the table in another schema and want to import the data from my excel file over. Step 0: The Empty Oracle Table and your Excel File You have an Oracle table and you have one or more Excel files. You may have an Excel file with 100 columns but your table only has 30. This is where you tell SQL Developer what columns are to be used for the import. You can also change up the column order, which may make the next step a bit easier.

Step 6: If you’re not paying attention and just letting the wizard guide you home, then now is the time to wake up. There’s a good chance the column order of the Excel file won’t match the definition of your table. This is where you will tell SQL Developer what columns in the spreadsheet match up to what columns in the Oracle table. Step 7: Verify your settings Hit the ‘verify’ button.

Fix any mistakes. Ruh roh raggy! SQL Developer is telling you it doesn’t know how to reconcile the data for this DATE column. We need to know what the is. So we need to go back to the Column definition wizard and inspect the HIRE_DATE column settings. You need to look at how the dates are stored in the spreadsheet and write them in terms that Oracle can understand. This will be used on the INSERTs via a TO_DATE() function that will turn your Excel string into an actual DATE value.

After correcting this, go back to the Verification screen and see if that fixes the problem. I have been using this process for several months. Works flawlessly each and everytime. Users fill in hundreds of rows on a spreadsheet, and I load it into the database in a matter of minutes. So I get a list of course sessions to load into a table and on step 4, I get a SERIOUS error messageSource columns mapped to the same target table column COURSE:CNAME, Table column name is COURSE, name of column on spreadsheet is CNAME.

This is the first time I have encountered this. What does the error mean? I have a csv file that I want to load using import data, one column is a DATE data type. I cannot format the csv input file correctly for nulls. I have tried using the word null,null with quotes ‘null’, nothing or two quotes together and the to_date() function.

The import data tool does not like the null values in the csv. I get an error stating the Data is not compatible with column definition or is not available for a not nullable column. Corel Ulead Videostudio X5 there. The column is a DATE column nulls are allowed all the other dates work but the nulls do not. Hi, I encountered an odd problem during import of data from excel. I work with PL/SQL Developer 10.* on my laptop, accessing remote oracle server.
