Specified by:

bindLimitParametersAtStartOfQuery in interface LimitHandler

Overrides:

bindLimitParametersAtStartOfQuery in class AbstractLimitHandler

Parameters:

statement - Statement to which to bind limit parameter values.

index - Index from which to start binding.

Returns:

The number of parameter values bound.

bindLimitParametersAtEndOfQuery
