Question

所以MySQLi语句无法准备错误，说它的语法不正确。但是，当我复制准备好的语句并直接在dbhost上使用它时，它可以正常工作。

这是准备的代码。

function sanitiseStatement($sql, $params)
{
  global $mysqli;

  $stmt = mysqli_stmt_init($mysqli);
  if (mysqli_stmt_prepare($stmt, $sql))
  {
    call_user_func_array(array($stmt, 'bind_param'), refValues($params));

    return $stmt;
  }
  error_log("Failed to prepare statement: ".mysqli_stmt_error($stmt));
  die ("Failed to prepare statement: ".mysqli_stmt_error($stmt));
}

这是传递给它的SQL语句。

START TRANSACTION; INSERT INTO Recipe (UserID, RecipeName, Difficulty, Servings) VALUES (?, ?, ?, ?); SET @recipe_ID = LAST_INSERT_ID(); INSERT INTO Instructions (InstructionNumber, RecipeID, Instruction, Duration) VALUES (?, @recipe_ID, ?, ?);  INSERT IGNORE INTO Ingredients (IngredientName) VALUES (?);  INSERT INTO RecipeIngredients (RecipeID , IngredientID,Quantity, Required) SELECT @recipe_ID AS RecipeID, IngredientID, ? AS quantity, ? AS required FROM Ingredients WHERE IngredientName = ?;  COMMIT;

这是错误日志和参数。

我很困惑，因为我在SQL语句中找不到错误，并且在将它直接与数据库一起使用时似乎有效。

PHP：语句无法准备，但SQL是正确的
