QVariant QPSQLResult::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.

QVariant QPSQLResult::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 QPSQLResult::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.

bool QPSQLResult::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.

bool QPSQLResult::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.

i

)

[protected, virtual]

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

int QPSQLResult::numRowsAffected

(

)

[protected, virtual]

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

bool QPSQLResult::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.
