The expression evaluator uses Integration Services data types. When data first enters a data flow in an Integration Services package, the data flow engine converts all column data to an Integration Services data type, and the column data that an expression uses already has an Integration Services data type.
Cost of Collagen Injections. On average, each collagen injection costs between $350 and $450 [sources: RealSelf, Bernstein ]. This price depends on where the patient receives treatment; in larger urban areas, the cost per injection could be more than $500.Costs can add up quickly because biodegradable collagen injections break down in three to six months, just like the collagen your body naturally produces.his price depends on where the patient receives treatment; in larger urban areas, the cost per injection could be more than $500.

One limiting factor in the use of preexposure rabies immunization is the cost of the vaccine in most developed countries. In the United States, rabies vaccine may cost more than $300 per dose, resulting in a cost to the patient in excess of $900 for three 1.0-mL intramuscular injections. As a way of decreasing the cost of preexposure immunization, some practitioners have used a 0.1-mL dose of rabies vaccine administered intradermally. At approximately $45 per dose in the early 1980s, many people already considered the vaccine too expensive.
