How to change timestamp in Db2?

I have created a table called 'Chicago crime data' I need to do some queries on it but the table wont load. The message i get is (timestamp format does not match data in the column 'UPDATEDON')

What is populated in the Date column is MM-DD-YYYY, I need to change it to DD-MM-YYYY HH:MM:SS. I have tried selecting the DD-MM-YYYY under the dropdown of Date Format and then the HH:MM:SS under Timestamp format, but when i complete and begin the load, it says the load succeeded but all 533 rows rejected and when i attempt to view the table (understandably) it says there is no data here yet.

To my understanding you should be able to do a custom change on the time format, but i cant see how? Any help would be much appreciated. Thanks.

I did it with pandas: First I have opened Jupyter-Notebook, and read the csv:

    df = pd.read_csv("Chicago_Crime_Data-v2.csv")

Then I used this function:

    df['DATE'] = pd.to_datetime(df.DATE)

And I save it back to the file:

    df.to_csv("Chicago_Crime_Data-v2.csv")

Now it would accept it. (Just see if there is more than one column with this problem)

Simply click on the timestamp dropdown and start typing your custom timestamp which in this case is "MM/DD/YYYY HH:MM:SS TT"

I too faced the same issue. I fixed it by as below:

  1. Paste some random text into TIMESTAMP dropdown field, then you edit option will be enabled for the field As in this pic

2. Then enter your desired timestapm(in your case: MM/DD/YYYY HH:MM:SS TT) 3. Ignore the warinigs and proceed further. You will be able to upload without any rejections.

I had this same problem on this IBM course - I found that the way around it was to try to paste something into the Timestamp format box on db2. This worked even though I previously hadn't been able to type in that box, and once I had pasted something I was able to type in that box again.
