(PECL CUBRID >= 8.3.1)

cubrid_querySend a CUBRID query


resource cubrid_query ( string $query [, resource $conn_identifier ] )

cubrid_query() sends a unique query (multiple queries are not supported) to the currently active database on the server that's associated with the specified conn_identifier.



An SQL query

Data inside the query should be properly escaped.


The CUBRID connection. If the connection identifier is not specified, the last connection opened by cubrid_connect() is assumed.


For SELECT, SHOW, DESCRIBE, EXPLAIN and other statements returning resultset, cubrid_query() returns a resource on success, or FALSE on error.

For other type of SQL statements, INSERT, UPDATE, DELETE, DROP, etc, cubrid_query() returns TRUE on success or FALSE on error.

The returned result resource should be passed to cubrid_fetch_array(), and other functions for dealing with result tables, to access the returned data.

Use cubrid_num_rows() to find out how many rows were returned for a SELECT statement or cubrid_affected_rows() to find out how many rows were affected by a DELETE, INSERT, REPLACE, or UPDATE statement.

cubrid_query() will also fail and return FALSE if the user does not have permission to access the table(s) referenced by the query.

例1 Invalid Query

The following query is syntactically invalid, so cubrid_query() fails and returns FALSE.


$result cubrid_query('SELECT * WHERE 1=1');
if (!
$result) {
'Invalid query: ' cubrid_error());


例2 Valid Query

The following query is valid, so cubrid_query() returns a resource.

// This could be supplied by a user, for example
$firstname 'fred';
$lastname  'fox';

$conn cubrid_connect('localhost'33000'demodb');

cubrid_execute($conn,"DROP TABLE if exists friends");
cubrid_execute($conn,"create table friends(firstname varchar,lastname varchar,address char(24),age int)");
cubrid_execute($conn,"insert into friends values('fred','fox','home-1','20')");
cubrid_execute($conn,"insert into friends values('blue','cat','home-2','21')");
// Formulate Query
// This is the best way to perform an SQL query
// For more examples, see cubrid_real_escape_string()
$query sprintf("SELECT firstname, lastname, address, age FROM friends WHERE firstname='%s' AND lastname='%s'",

// Perform Query
$result cubrid_query($query);

// Check result
// This shows the actual query sent to CUBRID, and the error. Useful for debugging.
if (!$result) {
$message  'Invalid query: ' cubrid_error() . "\n";
$message .= 'Whole query: ' $query;

// Use result
// Attempting to print $result won't allow access to information in the resource
// One of the cubrid result functions must be used
// See also cubrid_result(), cubrid_fetch_array(), cubrid_fetch_row(), etc.
while ($row cubrid_fetch_assoc($result)) {

// Free the resources associated with the result set
// This is done automatically at the end of the script
