[−][src]Struct sqlparser::ast::WindowFrame
Specifies the data processed by a window function, e.g.
RANGE UNBOUNDED PRECEDING
or ROWS BETWEEN 5 PRECEDING AND CURRENT ROW
.
Note: The parser does not validate the specified bounds; the caller should
reject invalid bounds like ROWS UNBOUNDED FOLLOWING
before execution.
Fields
units: WindowFrameUnits
start_bound: WindowFrameBound
end_bound: Option<WindowFrameBound>
The right bound of the BETWEEN .. AND
clause. The end bound of None
indicates the shorthand form (e.g. ROWS 1 PRECEDING
), which must
behave the same as end_bound = WindowFrameBound::CurrentRow
.
