Constructors
SQLiteStatementImpl
SQLiteStatementImpl(
Poco::Data::SessionImpl & rSession,
sqlite3 * pDB
);
Creates the SQLiteStatementImpl.
Destructor
~SQLiteStatementImpl 
Destroys the SQLiteStatementImpl.
Member Functions
affectedRowCount 
int 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.
bindImpl
void bindImpl();
Binds parameters
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 statement can compile.
See also: Poco::Data::StatementImpl::canCompile()
columnsReturned
std::size_t columnsReturned() const;
Returns number of columns returned by query.
compileImpl
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.
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()
next
std::size_t next();
Retrieves the next row from the resultset and returns 1. Will throw, if the resultset is empty.
