cubrid_unbuffered_query — Perform a query without fetching the results into memory
$query
[, resource $conn_identifier
] )This function performs a query without waiting for that all query results have been complete. It will return when the results are being generated.
query
A SQL query.
conn_identifier
The CUBRID connection. If the connection identifier is not specified, the last connection opened by cubrid_connect() is assumed.
For SELECT, SHOW, DESCRIBE or EXPLAIN statements returns a request identifier resource on success.
For other type of SQL statements, UPDATE, DELETE, DROP, etc, returns TRUE
on success.
FALSE
on failure.
Note:
The benefits of cubrid_unbuffered_query() come at a cost: you cannot use cubrid_num_rows() and cubrid_data_seek() on a result set returned from cubrid_unbuffered_query() .
Example #1 cubrid_unbuffered_query() example
<?php
$link = cubrid_connect ( "localhost" , 30000 , "demodb" , "dba" , "" );
if (! $link )
{
die( 'Could not connect.' );
}
$query = "select * from code" ;
$result = cubrid_unbuffered_query ( $query , $link );
while ( $row = cubrid_fetch ( $result ))
{
var_dump ( $row );
}
cubrid_close_request ( $result );
cubrid_disconnect ( $link );
