Using indicator variables for truncated values

Indicator variables indicate whether any fetched values were truncated to fit into a host variable. This enables applications to handle truncation appropriately.

If a value is truncated on fetching, the indicator variable is set to a positive value, containing the actual length of the database value before truncation. If the length of the value is greater than 32767 bytes, then the indicator variable contains 32767.
