cubrid_query - Send a CUBRID query

Manual

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

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.

Parameters

query

An SQL query

Data inside the query should be properly escaped.

conn_identifier

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.

// 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);
