-> begin

->  if not exists (select movie_name from music where music.movie_name=movie_name) then

-> insert into music(movie_name,movie_image,music_director,cast) values(movie_name,movie_image,music_director,cast);

-> insert into music_details(songtitle,duration,artist,lyricist,status,music_id) values(songtitle,duration,artist,lyricist,status,(select music_id from music where music.movie_name=movie_name));

 -> else

-> insert into music_details(songtitle,duration,artist,lyricist,status,music_id) values(songtitle,duration,artist,lyricist,status,(select music_id from music where music.movie_name=movie_name));

Answer 1

在您的代码中添加end if;

mysql> delimiter //

mysql> create procedure music_procedure(in movie_name varchar(100),in movie_image varchar(100),in music_director varchar(150),in cast varchar(150),in songtitle varchar(150),in duration time,in artist varchar(100),in lyricist varchar(100),in status varchar(50))

-> begin

->  if not exists (select movie_name from music where music.movie_name=movie_name) then

-> insert into music(movie_name,movie_image,music_director,cast) values(movie_name,movie_image,music_director,cast);

-> insert into music_details(songtitle,duration,artist,lyricist,status,music_id) values(songtitle,duration,artist,lyricist,status,(select music_id from music where music.movie_name=movie_name));

 -> else

-> insert into music_details(songtitle,duration,artist,lyricist,status,music_id) values(songtitle,duration,artist,lyricist,status,(select music_id from music where music.movie_name=movie_name));


-> end if;


-> //

Answer 2

你只是遗漏了END IF;。把它放在END声明之前;
