Method Detail

declareFields

boolean declareFields()

Whether the current context is rendering a SQL field declaration (e.g. a Field in the SELECT clause of the query).

declareFields

C declareFields(boolean declareFields)

Set the new context value for declareFields()

declareTables

boolean declareTables()

Whether the current context is rendering a SQL table declaration (e.g. a Table in the FROM or JOIN clause of the query).

declareTables

C declareTables(boolean declareTables)

Set the new context value for declareTables()

subquery

boolean subquery()

Whether the current context is rendering a sub-query (nested query)

subquery

C subquery(boolean subquery)

Set the new context value for subquery()

nextIndex

int nextIndex()

Get the next bind index. This increments an internal counter. This is relevant for two use-cases:

• When binding variables to a PreparedStatement. Client code must assure that calling nextIndex() is followed by setting a bind value to BindContext.statement()
• When rendering unnamed bind variables with RenderContext.namedParams() being to true

peekIndex

int peekIndex()

Peek the next bind index. This won't increment the internal counter, unlike nextIndex()
