Member Function Documentation

bool odbc::ResultSet::absolute (int row)

Moves the cursor to a specific row in this result set.

If row is negative, the actual row number is calculated from the end of the result set. Calling absolute(0) is equivalent to calling beforeFirst()

Returns:
true if the cursor is in the result set

bool odbc::ResultSet::relative (int rows)

Moves the cursor inside the result set relative to the current row.

Negative values are allowed. This call is illegal if there is no current row.

Returns:
true if the cursor is in the result set

int odbc::ResultSet::getRow ()

Returns the current row number.

Returns:
The current row number in the result set, or 0 if it can't be determined.

bool odbc::ResultSet::next ()

Moves to the next row in the result set.

Returns:
true if the cursor is in the result set

bool odbc::ResultSet::previous ()

Moves to the previous row in the result set.

Returns:
true if the cursor is in the result set

bool odbc::ResultSet::first ()

Moves to the first row in the result set.

Returns:
true if the cursor is in the result set

bool odbc::ResultSet::last ()

Moves to the last row in the result set.

Returns:
true if the cursor is in the result set

void odbc::ResultSet::moveToInsertRow ()

Moves the cursor to the 'insert row' of this result set.

Warning:
The only valid methods while on the insert row are updateXXX(), insertRow() and moveToCurrentRow().
See also:
moveToCurrentRow()

void odbc::ResultSet::insertRow ()

Inserts the current row.

Only valid while on the insert row.

See also:
moveToInsertRow()
