如何获取mysqli_stmt-object的预处理语句?
如果在执行mysql语句时出错,我想返回语句。
$id = "89c483c8";
$query = "SELECT * FROM database WHERE id = ?";
if (!($stmt = $database->prepare($query) { ... }
else {
$stmt->bind_param("s", $id);
if (!$stmt->execute())
return $stmt->get_statement; //doesn't exist
}
“$ stmt-> get_statement”当然不起作用。那么如何获得完整的查询?在这个例子中:
"SELECT * FROM database WHERE id = 89c483c8"

这是捕获sql错误的最佳方法:
const enhancer = compose(
applyMiddleware(ReduxThunk),
applyMiddleware(logger),
persistState(null, 'redux')
);
或者最简单的方法:
try {
$res = $mysqli_instance->query($query);
}catch (mysqli_sql_exception $e) {
print "Error Code <br>".$e->getCode();
print "Error Message <br>".$e->getMessage();
print "Strack Trace <br>".nl2br($e->getTraceAsString());
}
