Explanation:
According to the online Java tutorial provided by Sun at java.sun.com An
SQLWarning is a subclass of SQLException, but is not thrown like other
exceptions. The programmer must specifically ask for warnings. Connections,
Statements, and ResultSets all have a getWarnings(. method that allows retrieval.
There is also a clearWarnings(. method to avoid duplicate retrievals. The
SQLWarning class itself only adds the methods getNextWarning(. and
setNextWarning(.. An SQLWarning is very similar to traditional compiler
warnings something not exactly right occurred, but its effect was not severe enough
to end processing. Whether it is important enough to investigate depends on the
operation and context.
