FrontBase Funcţiifbsql_affected_rows
(PHP 4 >= 4.0.6, PHP 5)
fbsql_affected_rows — Get number of affected rows in previous FrontBase operation
Descrierea
fbsql_affected_rows() returns the number of rows affected by the last INSERT, UPDATE or DELETE query associated with link_identifier .
Notă: If you are using transactions, you need to call fbsql_affected_rows() after your INSERT, UPDATE, or DELETE query, not after the commit.
If the last query was a DELETE query with no WHERE clause, all of the records will have been deleted from the table but this function will return zero.
Notă: When using UPDATE, FrontBase will not update columns where the new value is the same as the old value. This creates the possibility that fbsql_affected_rows() may not actually equal the number of rows matched, only the number of rows that were literally affected by the query.
Parametri

-
Un identificator de legătură FrontBase întors de fbsql_connect() sau fbsql_pconnect().
Dacă nu este specificat, funcţia va încerca să găsească o legătură deschisă către serverul FrontBase şi dacă nu este găsită nici o astfel de legătură, se va încerca crearea uneia, ca şi la apelarea fbsql_connect() fără argumente.
Valorile întroarse
