The second Insert does not work in my trigger - mysql

Question

I am trying to learn more about triggers and I wrote a simple SQL code in MySQL.
This code will work with one insert but it will cause an error when I add the second insert.
I think the code that I wrote does not compile the second insert.
I would be appreciate for Any Help
Code:
create trigger MasterInputTRG
after insert on MasterInput
for each row
insert into NewEMCtestPLAN(ProjectNumber,Manufacture,ModelName,`PO Number`,AccountExecutive,AENotes) values(NEW.ProjectNumber,NEW.Applicant,NEW.ModelName,NEW.PONumber,NEW.AccountExecutive,NEW.AENotes);
insert into NewRF(ProjectNumber,Applicant,ModelName,PONumber,AccountExecutive,AENotes) values(NEW.ProjectNumber,NEW.Applicant,NEW.ModelName,NEW.PONumber,NEW.AccountExecutive,NEW.AENotes);
Error:
Syntax error near 'insert into
NewEMCtestPLAN(ProjectNumber,Applicant,ModelName,PONumber,AccountExe'
at line 5
Update:
I got an answer and I add the other code with errors here.:
Second Code that does not work:
create trigger MasterInputTRG
after insert on MasterInput
for each row
BEGIN
insert into NewEMCtestPLAN(ProjectNumber,Manufacture,ModelName,`PO Number`,AccountExecutive,AENotes) values(NEW.ProjectNumber,NEW.Applicant,NEW.ModelName,NEW.PONumber,NEW.AccountExecutive,NEW.AENotes);
insert into NewRF(ProjectNumber,Applicant,ModelName,PONumber,AccountExecutive,AENotes) values(NEW.ProjectNumber,NEW.Applicant,NEW.ModelName,NEW.PONumber,NEW.AccountExecutive,NEW.AENotes);
END
Errors:
Error in query (1054): Unknown column 'NEW.ProjectNumber' in 'field
list'
But this error did not appear when i used the new.projectnumber in first insert.
second error:
Error in query (1064): Syntax error near 'END' at line 1

Answer 1

A trigger body with multiple statements need to be surrounded bei BEGIN and END. But then (depending on your client) you might need to change the delimiter:
delimiter //
create trigger MasterInputTRG
after insert on MasterInput
for each row
begin
insert into NewEMCtestPLAN (...) values (...);
insert into NewRF (...) values (...);
end //
delimiter ;
The same applies to stored procedures and functions.
Note that the CREATE TRIGGER statement is a single.. well.. statement. Statements are delimited by.. well.. a delimiter. So in your original query the trigger definition ends with the first delimiter (;):
create trigger MasterInputTRG
after insert on MasterInput
for each row
insert into NewEMCtestPLAN (...) values (...); -- trigger ends here
-- anything else is outside the trigger
insert into NewRF (...) values (...);
The second insert could be a valid statement but outside the trigger definition. However I would expect a different error message like: unknown table (alias) 'NEW', because NEW is not known outside the trigger.
Now if we change the delimiter to //, the create statement ends after the first occurance of //, so we can use ; in the trigger body without terminating the CREATE statement.
Usually // or $$ are used for a delimiter. You can try something else, but it should not have any meaning in (My)SQL. For example | is a bit operator.

You should add Begin End in the trigger.
create trigger MasterInputTRG
after insert on MasterInput
for each row
BEGIN
insert into NewEMCtestPLAN(ProjectNumber,Manufacture,ModelName,`PO Number`,AccountExecutive,AENotes) values(NEW.ProjectNumber,NEW.Applicant,NEW.ModelName,NEW.PONumber,NEW.AccountExecutive,NEW.AENotes);
insert into NewRF(ProjectNumber,Applicant,ModelName,PONumber,AccountExecutive,AENotes) values(NEW.ProjectNumber,NEW.Applicant,NEW.ModelName,NEW.PONumber,NEW.AccountExecutive,NEW.AENotes);
END
