renderCondition

public FragmentAndParameters renderCondition(RenderingContext renderingContext,
 BindableColumn<T> leftColumn)

Description copied from interface: RenderableCondition

Render a condition - typically a condition in a WHERE clause.

A rendered condition includes an SQL fragment, and any associated parameters. For example, the isEqual condition should be rendered as "= ?" where "?" is a properly formatted parameter marker (the parameter marker can be computed from the RenderingContext). Note that a rendered condition should NOT include the left side of the phrase - that is rendered by the RenderableCondition.renderLeftColumn(RenderingContext, BindableColumn) method.

Specified by:

renderCondition in interface RenderableCondition<T>

Parameters:

renderingContext - the current rendering context

leftColumn - the column related to this condition in a where clause

Returns:

the rendered condition. Should NOT include the column.
