org.datanucleus.store.rdbms.sql.expression.SQLExpressionFactory.newLiteralParameter()
Factory for a literal as an input parameter. If the mapping (type of parameter) is not known at this point then put in null and it will return a ParameterLiteral. @param stmt The statement @param mapping The mapping @param value Value of the literal (if known) @param paramName The parameter name @return The literal
