Public Member Functions | |
UseQueryResult () | |
Default constructor. | |
UseQueryResult (MYSQL_RES *result, DBDriver *dbd, bool te=true) | |
Create the object, fully initialized. | |
UseQueryResult (const UseQueryResult &other) | |
Create a copy of another UseQueryResult object. | |
~UseQueryResult () | |
Destroy object. | |
UseQueryResult & | operator= (const UseQueryResult &rhs) |
Copy another UseQueryResult object's data into this object. | |
const Field & | fetch_field () const |
Returns the next field in this result set. | |
const Field & | fetch_field (Fields::size_type i) const |
Returns the given field in this result set. | |
const unsigned long * | fetch_lengths () const |
Returns the lengths of the fields in the current row of the result set. | |
Row | fetch_row () const |
Returns the next row in a "use" query's result set. | |
MYSQL_ROW | fetch_raw_row () const |
Wraps mysql_fetch_row() in MySQL C API. | |
void | field_seek (Fields::size_type field) const |
Jumps to the given field within the result set. | |
operator MYSQL_RES * () const | |
Return the pointer to the underlying MySQL C API result set object. |
See the user manual for the reason you might want to use this even though its interface is less friendly than StoreQueryResult's.
|
Returns the lengths of the fields in the current row of the result set.
|
|
Wraps mysql_fetch_row() in MySQL C API.
|
|
Returns the next row in a "use" query's result set. This is a thick wrapper around DBDriver::fetch_row(). It does a lot of error checking before returning the Row object containing the row data.
|
|
Jumps to the given field within the result set. Calling this allows you to reset the default field index used by fetch_field(). |
|
Return the pointer to the underlying MySQL C API result set object.
Query q("...."); if (UseQueryResult res = q.use()) { // Can use 'res', query succeeded } else { // Query failed, call Query::error() or ::errnum() for why } |
