void bindImpl();

Binds parameters

binder protected virtual inline

AbstractBinder & binder();

Returns the concrete binder used by the statement.

canBind protected virtual

bool canBind() const;

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

columnsReturned protected virtual inline

Poco::UInt32 columnsReturned() const;

Returns number of columns returned by query.

compileImpl protected virtual

void compileImpl();

Compiles the statement, doesn't bind yet

extractor protected virtual inline

AbstractExtractor & extractor();

Returns the concrete extractor used by the statement.

hasNext protected virtual

bool hasNext();

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

metaColumn protected virtual inline

const MetaColumn & metaColumn(
    Poco::UInt32 pos
) const;

Returns column meta data.

nativeSQL protected

std::string nativeSQL();

Returns the SQL string as modified by the driver.

next protected virtual

void next();
