INTERVAL_LIMIT_KIND enumeration (structuredquery.h)

  • Article

These values are returned by IInterval::GetLimits as pairs to specify a range with an upper and lower limit. INTERVAL_LIMIT_KIND identifies whether the ranges include or exclude the upper and lower values of the range, and whether a range begins or ends in infinity.

Syntax

typedef enum tagINTERVAL_LIMIT_KIND {
  ILK_EXPLICIT_INCLUDED = 0,
  ILK_EXPLICIT_EXCLUDED,
  ILK_NEGATIVE_INFINITY,
  ILK_POSITIVE_INFINITY
} INTERVAL_LIMIT_KIND;

Constants

 
ILK_EXPLICIT_INCLUDED
Value: 0
The value is included in the range. For example, an integer range of numbers that is equal to or greater than 3 and less than or equal to 6 includes both 3 and 6. So the values 3 and 6 would both be returned with ILK_EXPLICIT_INCLUDED.
ILK_EXPLICIT_EXCLUDED
The value bounds the range but is not included in the range. For example, an integer range that is greater than 3 but less than 6 excludes both 3 and 6. So the values would both be returned with ILK_EXPLICIT_EXCLUDED.
ILK_NEGATIVE_INFINITY
This is typically used as a lower bound. The specified value is ignored because the range begins (or ends) at negative infinity. For example, an integer range that includes every value less than 6 would have ILK_NEGATIVE_INFINITY for the lower bound and 6 and ILK_EXPLICIT_EXCLUDED for the upper bound.
ILK_POSITIVE_INFINITY
This is typically used as an upper bound. The specified value is ignored because the range begins (or ends) at positive infinity. For example, an integer range that includes every value greater than or equal to 3 would have ILK_EXPLICIT_INCLUDED and 3 for the lower bound and ILK_POSITIVE_INFINITY for the upper bound.
