Method Detail

getMonotonicity

public SqlMonotonicity getMonotonicity(SqlCall call,
                              SqlValidatorScope scope)

Description copied from class: SqlOperator

Returns whether this operator is monotonic.

Default implementation returns SqlMonotonicity.NOT_MONOTONIC.

Overrides:

getMonotonicity in class SqlBinaryOperator

Parameters:

call - Call to this operator

scope - Scope in which the call occurs
