    • Method Detail

      • accept

        public abstract void accept​(Context<?> ctx)
        Subclasses must implement this method.
        This QueryPart can accept a Context object in order to render a SQL string or to bind its variables.
      • clauses

        public final Clause[] clauses​(Context<?> ctx)
        Description copied from interface: QueryPartInternal
        The Clauses that are represented by this query part.

        QueryParts can specify several Clauses for which an event will be emitted before (in forward order) and after (in reverse order) visiting the the query part through Context.visit(QueryPart)

        This method is for JOOQ INTERNAL USE only. Do not reference directly

        Specified by:
        clauses in interface QueryPartInternal
        The Clauses represented by this query part or null or an empty array if this query part does not represent a clause.
      • toSQL

        public final void toSQL​(RenderContext context)
        - 3.4.0 - [#2694] - Use QueryPartInternal.accept(Context) instead.
        Description copied from interface: QueryPartInternal
        Render this QueryPart to a SQL string contained in context.sql(). The context will contain additional information about how to render this QueryPart, e.g. whether this QueryPart should be rendered as a declaration or reference, whether this QueryPart's contained bind variables should be inlined or replaced by '?', etc.

        toSQL in interface QueryPartInternal
      • equals

        public boolean equals​(java.lang.Object that)
        Description copied from interface: QueryPart
        Check whether this QueryPart can be considered equal to another QueryPart.

        In general, QueryPart equality is defined in terms of QueryPart.toString() equality. In other words, two query parts are considered equal if their rendered SQL (with inlined bind variables) is equal. This means that the two query parts do not necessarily have to be of the same type.

        Some QueryPart implementations may choose to override this behaviour for improved performance, as QueryPart.toString() is an expensive operation, if called many times.

        Specified by:
        equals in interface QueryPart
        equals in class java.lang.Object
        that - The other QueryPart
        Whether the two query parts are equal
      • hashCode

        public int hashCode()
        Description copied from interface: QueryPart
        Generate a hash code from this QueryPart.

        In general, QueryPart hash codes are the same as the hash codes generated from QueryPart.toString(). This guarantees consistent behaviour with QueryPart.equals(Object)

        Some QueryPart implementations may choose to override this behaviour for improved performance, as QueryPart.toString() is an expensive operation, if called many times.

        Specified by:
        hashCode in interface QueryPart
        hashCode in class java.lang.Object
        The QueryPart hash code
      • toString

        public java.lang.String toString()
        Description copied from interface: QueryPart
        Render a SQL string representation of this QueryPart.

        For improved debugging, this renders a SQL string of this QueryPart with inlined bind variables. If this QueryPart is Attachable, then the attached Configuration may be used for rendering the SQL string, including SQLDialect and Settings. Do note that most QueryPart instances are not attached to a Configuration, and thus there is no guarantee that the SQL string will make sense in the context of a specific database.

        Specified by:
        toString in interface QueryPart
        toString in class java.lang.Object
        A SQL string representation of this QueryPart
      • translate

        protected final DataAccessException translate​(java.lang.String sql,
                                                      java.sql.SQLException e)
