odbx_row_fetch — Retrieve rows from the result set
Retrieves the values of a row from the current result set returned by odbx_result(). Until this function is invoked, no row and field data is available via odbx_field_length() or odbx_field_value() and these functions will return zero respectively NULL.
Moreover, it is necessary to fetch all rows from a result set until zero is returned indicating that no more rows are available. Otherwise - depending on the backend - an error may occur after calling odbx_result() the next time or the outstanding rows will be returned within the next result.
odbx_row_fetch() requires a valid
result object which was created by odbx_result(). It must not have been feed to odbx_result_finish() before.
odbx_row_fetch() will return
ODBX_ROW_NEXT ("1") as long as rows are available from the result set. After the last row has been made available, further calls to this function will return
ODBX_ROW_DONE ("0") indicating that the result set doesn't contain more rows. The named constants are available since OpenDBX 1.3.2 and the numbers in brackets have to be used instead if a previous release is is the basis for the application development.
In case of an error, values less than zero are returned encodeing the reason why the error occurred.
resultparameter is either NULL or the object is invalid. This is usually the case if result has been already feed to odbx_result_finish().
