NpowerNorthern_v1 a INNER JOIN EPPS. If you cannot accurately type the values involved in multiplication and division, for example if they are procedure parameters that are called with wildly different values, you may want to look into approximate numeric types (float, real), or perhaps define your own very high capacity user defined exact numeric data type using the CLR. 5, then it rounds away from zero to the integer with larger magnitude. The norm for basic value types is that they map a single database value (column) to a single, non-aggregated Java type.
