Hi everyone.
I am trying to insert data from an excel file into a table (trying to create Orders table from the Oracle OE Schema) using Import Wizard.
Following the solution provided in this thread, I first converted the numeric values to a text using Excel's Text to Columns function, (eg 44850.6540972222 becomes 16/10/2022 5:41:54)

The I right click on the table to import data to get into Import Wizard, in step 4. Column Definition, for the column ORDER_DATE, the format I put down is “DD/MM/YYYY HH24:MI:SS”. (Note there are two spaces after YYYY to match exact how it is in excel, excel put two spaces after YYYY after converting to text for some reason). From what I can see, the format I put down matches exactly the format in excel.

After click “Finish” in Import Wizard, I get the following error. It says ORDER_DATE null.

so I am stuck here.
I have attached the script I used to create Orders table and the excel file with converted date in text format if you need it to help me solve this issue.
Thank you in advance.
