StatementHelper is a simple helper class that assists TableQuery and the query generators in filling a PreparedStatement. The actual statement is generated by the query generator methods, but the resulting statement and all the parameter values are stored in an instance of StatementHelper. This class will also fill the values with correct setters into the PreparedStatement on request.

Handle unrecognized null values. Override this to handle null values for platform specific data types that are not handled by the default implementation of the StatementHelper.

Parameters:

i - index of the null parameter in the prepared statement's parameter list

pstmt - the prepared statement that contained the unrecognized null value

dataTypes - a type ID -> class mapping of known data types

Returns:

true if handled, false otherwise

Throws:

SQLException - should be thrown if the null cannot be handled
