Functions ¶
func WindowModeName ¶
func WindowModeName(mode WindowFrameMode) string
WindowModeName returns the name of the window frame mode.
Types ¶
type WindowFrameBoundType ¶
type WindowFrameBoundType int
WindowFrameBoundType indicates which type of boundary is used.
const ( // UnboundedPreceding represents UNBOUNDED PRECEDING type of boundary. UnboundedPreceding WindowFrameBoundType = iota // OffsetPreceding represents 'value' PRECEDING type of boundary. OffsetPreceding // CurrentRow represents CURRENT ROW type of boundary. CurrentRow // OffsetFollowing represents 'value' FOLLOWING type of boundary. OffsetFollowing // UnboundedFollowing represents UNBOUNDED FOLLOWING type of boundary. UnboundedFollowing )
func (WindowFrameBoundType) IsOffset ¶
func (ft WindowFrameBoundType) IsOffset() bool
IsOffset returns true if the WindowFrameBoundType is an offset.
func (WindowFrameBoundType) Name ¶
func (ft WindowFrameBoundType) Name() string
Name returns a string representation of the bound type to be used in struct names for generated code.
func (WindowFrameBoundType) String ¶
func (ft WindowFrameBoundType) String() string
type WindowFrameExclusion ¶
type WindowFrameExclusion int
WindowFrameExclusion indicates which mode of exclusion is used.
const ( // NoExclusion represents an omitted frame exclusion clause. NoExclusion WindowFrameExclusion = iota // ExcludeCurrentRow represents EXCLUDE CURRENT ROW mode of frame exclusion. ExcludeCurrentRow // ExcludeGroup represents EXCLUDE GROUP mode of frame exclusion. ExcludeGroup // ExcludeTies represents EXCLUDE TIES mode of frame exclusion. ExcludeTies )
func (WindowFrameExclusion) Name ¶
func (node WindowFrameExclusion) Name() string
Name returns a string representation of the exclusion type to be used in struct names for generated code.
func (WindowFrameExclusion) String ¶
func (node WindowFrameExclusion) String() string
type WindowFrameMode ¶
type WindowFrameMode int
WindowFrameMode indicates which mode of framing is used.
const ( // RANGE is the mode of specifying frame in terms of logical range (e.g. 100 units cheaper). RANGE WindowFrameMode = iota // ROWS is the mode of specifying frame in terms of physical offsets (e.g. 1 row before etc). ROWS // GROUPS is the mode of specifying frame in terms of peer groups. GROUPS )
func (WindowFrameMode) Name ¶
func (m WindowFrameMode) Name() string
Name returns a string representation of the window frame mode to be used in struct names for generated code.
func (WindowFrameMode) String ¶
func (m WindowFrameMode) String() string
