Question

I am trying to obtain a float value from my Database

The following checks if its null else returns 1; (works if null in DB but errors if a float)

month =  row.getString(39) != null ? row.getFloat(39): 1;

On the other hand, the following gets float directly. (works if float in DB but errors if null)

float test = row.getFloat(39);

How would I go about obtaining a float from the DB, and in the case of a null, return a default value. I cant get it in either format as it causes errors when in a diff format.

Preferably without changing the SQL statement. As since there are 45 variables, it would get far too big, messy and unmanageable. I havent looked into it, but I assume with SQL I can do some kind of IFNULL(field,default). Or maybe this is the best way… Although Id probably need AS field on the end too.

Answer 1

The following seems to work for any data type. Using getObject and checking if it is null. Even in the case of floats, where != null would otherwise be invalid comparison.

month =  row.getObject(39) != null ? row.getFloat(39): 1;
