|
* that have already been pre-fetched by the client library.
|
|
* This implies the following:
|
|
* - num_rows() always returns zero before the first fetch;
|
|
* - num_rows() for SELECT ... FOR UPDATE is broken -> never returns a
|
|
* higher number than the number of records fetched so far (no pre-fetch);
|
|
* - the result of num_rows() for other statements is merely a lower bound
|
|
* on the number of records => calling ibase_num_rows() again after a couple
|
|
* of fetches will most likely return a new (higher) figure for large result
|
