Question

I am copying some rows from a DB2 database usign a JDBC interface. My worry is this: Some columns are defined as DECIMAL 15. Internaly in DB2 these are stored as binary coded decimal. Copying these via a double precision variable in Java might lose some precision. As the program will run in a bank, this would definitely be a problem.

What’s the best way to handle that?

Answer 1

Why not use ResultSet.getBigDecimal()?

The Javadoc states:

Retrieves the value of the designated column in the current row of
this ResultSet object as a java.math.BigDecimal with full precision.
