cubrid_query 함수는 conn_identifier와 관련된 데이터베이스 서버에 하나의 질의를 보낸다. 여러 개의 질의를 보낼 수는 없다.
SELECT 문을 실행하여 얼마나 많은 행이 반환되는지 알기 위해서 cubrid_num_rows()를 호출하거나, DELETE, INSERT, REPLACE, UPDATE 문에 영향받는 행의 개수를 알기 위해서 cubrid_affected_rows()를 호출할 때 cubrid_query 함수가 반환하는 결과 식별자를 사용한다.
resource cubrid_query (resource $query[, resource $conn_identifier])
<?php
// This could be supplied by a user, for example
$firstname = 'fred';
$lastname = 'fox';
$conn = cubrid_connect('localhost', 33000, 'foo');
// Formulate Query
// This is the best way to perform an SQL query
// For more examples, see cubrid_real_escape_string()
$query = sprintf("SELECT firstname, lastname, address, age FROM friends WHERE firstname='%s' AND lastname='%s'",
cubrid_real_escape_string($firstname),
cubrid_real_escape_string($lastname));
// 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: ' . $query;
die($message);
}
// 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)) {
echo $row['firstname'];
echo $row['lastname'];
echo $row['address'];
echo $row['age'];
}
// Free the resources associated with the result set
// This is done automatically at the end of the script
cubrid_free_result($result);
