## Member Functions

### affectedRowCount

int affectedRowCount() const;

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

See also: Poco::Data::StatementImpl::affectedRowCount()

### bindImpl

void bindImpl();

Binds all parameters and executes the statement.

See also: Poco::Data::StatementImpl::bindImpl()

### binder

AbstractBinding::BinderPtr binder();

Returns the concrete binder used by the statement.

See also: Poco::Data::StatementImpl::binder()

### canBind

bool canBind() const;

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

See also: Poco::Data::StatementImpl::canBind()

### canCompile

bool canCompile() const;

Returns true if another compile is possible.

See also: Poco::Data::StatementImpl::canCompile()

### columnsReturned

std::size_t columnsReturned() const;

Returns number of columns returned by query.

See also: Poco::Data::StatementImpl::columnsReturned()

### compileImpl

void compileImpl();

Compiles the statement, doesn't bind yet. Does nothing if the statement has already been compiled.

See also: Poco::Data::StatementImpl::compileImpl()

### extractor

AbstractExtraction::ExtractorPtr extractor();

Returns the concrete extractor used by the statement.

See also: Poco::Data::StatementImpl::extractor()

### hasNext

bool hasNext();

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

See also: Poco::Data::StatementImpl::hasNext()

### metaColumn

const MetaColumn & metaColumn(
std::size_t pos
) const;

Returns column meta data.

See also: Poco::Data::StatementImpl::metaColumn()

### nativeSQL

std::string nativeSQL();

Returns the SQL string as modified by the driver.

### next

std::size_t next();

Retrieves the next row or set of rows from the resultset. Returns the number of rows retrieved. Will throw, if the resultset is empty.
