(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.

Return Values

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.


Example #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());


Example #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
