QVariant QODBCResult::data

(

int

i

)

[protected, virtual]

Returns the data for field i (zero-based) as a QVariant. This function is only called if the result is in an active state and is positioned on a valid record and i is non-negative. Derived classes must reimplement this function and return the value of field i, or QVariant() if it cannot be determined.

bool QODBCResult::exec

(

)

bool QODBCResult::fetch

(

int

i

)

[protected, virtual]

Positions the result to an arbitrary (zero-based) index i. This function is only called if the result is in an active state. Derived classes must reimplement this function and position the result to the index i, and call setAt() with an appropriate value. Return TRUE to indicate success, or FALSE to signify failure.

Implementa QSqlResult.

bool QODBCResult::fetchFirst

(

)

[protected, virtual]

Positions the result to the first record in the result. This function is only called if the result is in an active state. Derived classes must reimplement this function and position the result to the first record, and call setAt() with an appropriate value. Return TRUE to indicate success, or FALSE to signify failure.

Implementa QSqlResult.

bool QODBCResult::fetchLast

(

)

[protected, virtual]

Positions the result to the last record in the result. This function is only called if the result is in an active state. Derived classes must reimplement this function and position the result to the last record, and call setAt() with an appropriate value. Return TRUE to indicate success, or FALSE to signify failure.

Implementa QSqlResult.

bool QODBCResult::fetchNext

(

)

[protected, virtual]

Positions the result to the next available record in the result. This function is only called if the result is in an active state. The default implementation calls fetch() with the next index. Derived classes can reimplement this function and position the result to the next record in some other way, and call setAt() with an appropriate value. Return TRUE to indicate success, or FALSE to signify failure.

bool QODBCResult::fetchPrior

(

)

[protected]

bool QODBCResult::isNull

(

int

i

)

[protected, virtual]

Returns TRUE if the field at position i is NULL; otherwise returns FALSE.

Implementa QSqlResult.

int QODBCResult::numRowsAffected

(

)

[protected, virtual]

Returns the number of rows affected by the last query executed.

Implementa QSqlResult.

bool QODBCResult::prepare

(

const QString &

query

)

bool QODBCResult::reset

(

const QString &

query

)

[protected, virtual]

Sets the result to use the SQL statement query for subsequent data retrieval. Derived classes must reimplement this function and apply the query to the database. This function is called only after the result is set to an inactive state and is positioned before the first record of the new result. Derived classes should return TRUE if the query was successful and ready to be used, or FALSE otherwise.

Implementa QSqlResult.

int QODBCResult::size

(

)

[protected, virtual]

Returns the size of the result or -1 if it cannot be determined.
