我可以在 MySQL 的同一个查询中使用“LINES STARTING BY”和“LINES TERMINATED BY”吗？

Question

我正在研究一个使用两个准备好的语句（@aux1 和@aux2）将一些数据复制到文本文件中的过程。然后复制信息所在的表，获取所有删除的行。

问题是当我使用call copyIntoFile() 执行该过程时出现错误。

程序

delimiter !!
drop procedure if exists copyIntoFile !!
create procedure copyIntoFile()

begin
    declare path varchar(255);
    set path = concat("'C:/ProgramData/MySQL/MySQL Server 5.7/Uploads/", curdate(), ".txt'");

    set @aux1 = concat("select * from movie_modification where modified = true into outfile ", path, 
                        " fields terminated by ';' lines starting by 'Edit: ' lines terminated by '\n';");
    prepare stmt1 from @aux1;
    execute stmt1;
    deallocate prepare stmt1;

    set @aux2 = concat("select * from movie_modification where modified = false into outfile ", path, 
                        " fields terminated by ';' lines starting by 'New: ' lines terminated by '\n';");
    prepare stmt2 from @aux2;
    execute stmt2;
    deallocate prepare stmt2;

    delete from movie_modification;
end !!
delimiter ;

错误（执行过程时）

错误代码：1064。您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以获取正确的语法，以便在第 1 行的“由 ''' 终止的行附近使用正确的语法

如您所见，错误发生在lines terminated by 附近（第 1 行）。所以现在我想知道是否可以在lines starting by 之后使用lines terminated by，或者在每个查询中是否只接受其中一个语句。

怎么了？

Answer 1

我认为你需要替换这个：

select ...
into outfile ...
fields terminated by ';' lines starting by 'Edit: ' lines terminated by '\n'

与：

select ...
into outfile ...
fields terminated by ';' lines starting by 'Edit: ' terminated by '\n'

即：lines 关键字不应重复。
