Constructors
ODBCStatementImpl
ODBCStatementImpl(
SessionImpl & rSession
);
Creates the ODBCStatementImpl.
Destructor
~ODBCStatementImpl 
Destroys the ODBCStatementImpl.
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.
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.
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.
