クエリがあります。phpmyadminで実行したいものです。

しかし、実行するたびに、declareでエラーが発生しました。私はこれのエラーが何であるかを見つけることができませんか？

このコードブロックをPHPからのクエリとして実行したいですか？

たぶん、mysql区切り文字についての何かです。次のように実行してみてください。

シンプルな MySQL スクリプトでは、DECLARE、OPEN、FETCH、CLOSE などのステートメントの多くを使用できません。この目的のために、ソース オブジェクトを作成する必要があります。たとえば、ストアド プロシージャを使用して実行できます。ドキュメントに良い例があります - Cursors。

また、PRINT は MySQL ステートメントではありません。
