I'm working on a procedure that copies some data into a text file using two prepared statements (@aux1 and @aux2). Then the table where the information is copied, get's all of it's rows deleted.
The issue is that when I execute the procedure using call copyIntoFile() I get an error.
PROCEDURE
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 ;
ERROR (When executing the procedure)
Error Code: 1064. You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'lines terminated by ' '' at line 1
As you can see, the error occurs near lines terminated by (at line 1). So now I'm wondering if I can use lines terminated by after lines starting by or if just one of this statements is accepted in each query.
What's wrong?
I think you need to replace this:
select ...
into outfile ...
fields terminated by ';' lines starting by 'Edit: ' lines terminated by '\n'
With:
select ...
into outfile ...
fields terminated by ';' lines starting by 'Edit: ' terminated by '\n'
That is: the lines keyword should not be repeated.
