Récupère le nombre de lignes d'un jeu de résultat. Cette commande n'est
|
|
disponible que pour les requêtes comme SELECT ou SHOW qui retournent
|
|
un jeu de résultats. Pour récupérer le nombre de lignes
|
|
affectées par une requête INSERT, UPDATE, REPLACE ou DELETE, utilisez la
|
|
fonction <function>mysql_affected_rows</function>.
