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.

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.

I work with PL/SQL Developer 10.* on my laptop, accessing remote oracle server. So far I haven’t faced a problem during import from excel, till yesterday.

I tried to import 40K IDs from a single column to a temporary table in the base, made for this reason, with the same header name, only with one column and so on Which I have done it many times. But when I started the import an error message appeared, which was like this one – “You tried to insert a “NULL value into a column that does not accept NULL values” I think it was this error: In this moment I thought that there are blank rows in the excel, because I removed duplicates with the function in excel, which deletes the data only from the cells, not the rows. So I checked again, deleted the blank rows below the data, clear everything blank, but still nothing. In the error message box was a button “skip” (during the import), every time when I was able to press the button, I could see different indications – 66 records successfuly imported, 54 records, 32 and so on (on portions) I didn’t understand what was happening. I tried to move the data to another excel file with paste special, but nothing changed when I tried to import the data from the new file.
