SQLiteStatementImpl(
Poco::Data::SessionImpl & rSession,
sqlite3 * pDB
);
Creates the SQLiteStatementImpl.
Destroys the SQLiteStatementImpl.
std::size_t affectedRowCount() const;
Returns the number of affected rows. Used to find out the number of rows affected by insert, delete or update. All changes are counted, even if they are later undone by a ROLLBACK or ABORT. Changes associated with creating and dropping tables are not counted.
void bindImpl();
Binds parameters
See also: Poco::Data::StatementImpl::bindImpl()
AbstractBinding::BinderPtr binder();
Returns the concrete binder used by the statement.
See also: Poco::Data::StatementImpl::binder()
bool canBind() const;
Returns true if a valid statement is set and we can bind.
See also: Poco::Data::StatementImpl::canBind()
bool canCompile() const;
Returns true if statement can compile.
See also: Poco::Data::StatementImpl::canCompile()
std::size_t columnsReturned() const;
Returns number of columns returned by query.
void compileImpl();
Compiles the statement, doesn't bind yet. Returns true if the statement was succesfully compiled. The way SQLite handles batches of statmeents is by compiling one at a time and returning a pointer to the next one. The remainder of the statement is kept in a string buffer pointed to by _pLeftover member.

AbstractExtraction::ExtractorPtr extractor();
Returns the concrete extractor used by the statement.
See also: Poco::Data::StatementImpl::extractor()
bool hasNext();
Returns true if a call to next() will return data.
See also: Poco::Data::StatementImpl::hasNext()
const MetaColumn & metaColumn(
std::size_t pos
) const;
Returns column meta data.
See also: Poco::Data::StatementImpl::metaColumn()
std::size_t next();
Retrieves the next row from the resultset and returns 1. Will throw, if the resultset is empty.
