Member Functions
affectedRowCount 
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
virtual void bindImpl();
Binds parameters
See also: Poco::Data::StatementImpl::bindImpl()
binder
virtual Poco::Data::AbstractBinder::Ptr binder();
Returns the concrete binder used by the statement.
canBind
virtual bool canBind() const;
Returns true if a valid statement is set and we can bind.
See also: Poco::Data::StatementImpl::canBind()
canCompile
virtual bool canCompile() const;
Returns true if another compile is possible.
See also: Poco::Data::StatementImpl::canCompile()
columnsReturned
virtual std::size_t columnsReturned() const;
Returns number of columns returned by query.
compileImpl
virtual void compileImpl();
Compiles the statement, doesn't bind yet
See also: Poco::Data::StatementImpl::compileImpl()
extractor
virtual Poco::Data::AbstractExtractor::Ptr extractor();
Returns the concrete extractor used by the statement.
hasNext
virtual bool hasNext();
Returns true if a call to next() will return data.
See also: Poco::Data::StatementImpl::hasNext()
metaColumn
virtual const MetaColumn & metaColumn(
std::size_t pos
) const;
Returns column meta data.
See also: Poco::Data::StatementImpl::metaColumn()
next
virtual std::size_t next();
Retrieves the next row from the resultset. Will throw, if the resultset is empty.
