How should a sample FastLoad1.csv file look like?

Question

I tried to follow this example code

Everything works fine except this line 

              pstmtFld.setAsciiStream(1, dataStream, -1);

It throws SQL exception .

I suspect that the sample FastLoad1.csv file that i created is not consistent with their example . However i tried to create a very simple file with exactly the same fields . Here is my FastLoad1.csv 

L_INDEX,L_TIMESTAMP,L_TEXT 
1,01/01/13,testText
2,01/01/13,testText
3,01/01/13,testText
4,01/01/13,testText

Is it correct csv file . Is it consistent with the sample program ? If yes, why does it throw an exception ?

Here is the error message

 Attempting connection to Teradata with FastLoadCSV.

Was it helpful?

Solution 2

L_TIMESTAMP is supposed to be a timestamp, but it's a date in the CSV. And it's probably not in the correct format. Do a SHOW TABLE and check the FORMAT, then modify your data accordingly or add it to your INSERT:

VALUES(?,? (TIMESTAMP, FORMAT 'mm/dd/yy'),?)

And when you use a two-digit year you might not get the expected century (based on some dbscontrol settings)

OTHER TIPS

Yes, this is correct csv file. But, if you want generate dummy data in csv format, Here is a link http://dummydata.me/ Might be useful for you.
