fbsql_affected_rows
(PHP 4 >= 4.0.6, PHP 5)
fbsql_affected_rows — Get number of affected rows in previous FrontBase operation
Descrição
fbsql_affected_rows() returns the number of rows affected by the last INSERT, UPDATE or DELETE query associated with link_identifier .
Nota: 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.
Nota: 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.
Parâmetros
- link_identifier
-
Um identificador de conexão FrontBase retornado por fbsql_connect() ou fbsql_pconnect().
Se opcional e não especificado, a função tentará encontrar uma conexão aberta para o servidor FrontBase server e se não for encontrada uma conexão dessa ela irá tentar criar uma como se fbsql_connect() fosse chamada sem argumentos
Valor Retornado
If the last query failed, this function will return -1.
