SQLite3::enableExtendedResultCodes — Enables or disables the use of extended result codes
Enables or disables the use of extended result codes, which are then reported by SQLite3::lastErrorCode(). SQLite3::lastExtendedErrorCode() is not affected by this setting, and always returns the extended result code.
示例 #1 SQLite3::enableExtendedResultCodes() example
<?php
$db = new SQLite3(':memory:');
$db->enableExceptions(true);
$db->exec('CREATE TABLE t (a INTEGER UNIQUE)');
$db->exec('INSERT INTO t VALUES (1)');
try {
$db->exec('INSERT INTO t VALUES (1)');
} catch (Exception $e) {
}
// The primary result code (SQLITE_CONSTRAINT), then the extended result
// code (SQLITE_CONSTRAINT_UNIQUE).
var_dump($db->lastErrorCode(), $db->lastExtendedErrorCode());
// Once enabled, SQLite3::lastErrorCode() reports the extended result code
// as well.
$db->enableExtendedResultCodes();
var_dump($db->lastErrorCode());
?>以上示例会输出：
int(19) int(2067) int(2067)
