sybase_free_resultLibera um resultado da memória


sybase_free_result ( resource $result ) : bool

sybase_free_result() só precisa ser usado se você esta preocupado em usar muita memória enquando o seu script esta sendo executado. Toda a memória do resultado será automaticamente liberada quando o script terminar. Você pode utilizar sybase_free_result() com um identificador de resultado como argumento e a memória usada por este resultado será liberada.

When processing queries that return MANY rows, and when you put a limit on the number of rows you fetch from the result set, you should always call this function to close the current result set, because the SQL server may still be pending waiting for other rows to be fetched by your script. When you call this function, the Sybase client in PHP3 will signal to Sybase SQL Server that other pending results can be ignored, and the SQL server connection will return faster to the "waiting command" state, instead of keeping in the "suspend" state, saving much resources on the SQL-Server. In fact, it is  a good idea to call this function after all your queries to save up SQL server resources.
Note that when processing SQL batchs with multiple queries, and stored procedure calls that return multiple result sets, there's no provision here to let the server return the next result set. There should be another function like sybase_next_result() to close the current result set, and let the SQL server go on the next SQL statements. Such a function would return a status that indicates if further results are coming or if the query is really terminated.
