i am using preparestatement to insert muliple rows into database.
My problem is that in the 2nd addBatch block i dont want to insert any value into the col2, which is a numeric field.
And i dont want to do it in a different query.
How to do that.
What if the table entry is an integer but a foreign key to another table? setNull sets an integer to 0 and not null so the update fails as 0 is not a valid reference to another table. Is their a way to pass it the null sql type ...... set column=null ....... not ......set column=0....?
When I get the values via it returns 0 if column is null. I was not aware of that. So my object was storing 0. I had to put in a check and not populate the valriable in my object if 0 was returned. This works ok for me as the column in question is a foreign key and a 0 value is never valid. I would not know how to handle this if 0 was a valid value. Any suggestions?
