Member Functions

affectedRowCount protected virtual

virtual int affectedRowCount() const;

Returns the number of affected rows. Used to find out the number of rows affected by insert, delete or update.

bindImpl protected virtual

virtual void bindImpl();

Binds parameters

binder protected virtual

virtual Poco::Data::AbstractBinder::Ptr binder();

Returns the concrete binder used by the statement.

canBind protected virtual

virtual bool canBind() const;

Returns true if a valid statement is set and we can bind.

canCompile protected virtual

virtual bool canCompile() const;

Returns true if another compile is possible.

columnsReturned protected virtual

virtual std::size_t columnsReturned() const;

Returns number of columns returned by query.

compileImpl protected virtual

virtual void compileImpl();

Compiles the statement, doesn't bind yet

extractor protected virtual

virtual Poco::Data::AbstractExtractor::Ptr extractor();

Returns the concrete extractor used by the statement.

hasNext protected virtual

virtual bool hasNext();

Returns true if a call to next() will return data.

metaColumn protected virtual

virtual const MetaColumn & metaColumn(
    std::size_t aPosition
) const;

Returns column meta data.

next protected virtual

virtual std::size_t next();

Retrieves the next row from the resultset. Will throw, if the resultset is empty.
