找不到哪里是MySQL的语法错误

Question

delimiter %% 
create procedure getFileID(in fname varchar(100), out fId int) 
begin 
    select ID from File 
    where Name = fname 
    into fId; 
end %% 
delimiter ; 

delimiter $$ 
create procedure FileINFO(in fname varchar(100)) 
begin 
    declare SMS_done, Par_don boolean default false; 
    declare SMSID int; 
    declare SMSName varchar(100) default ""; 
    declare SMSCode varchar(100) default "";

    declare fId int default 0; 
    call getFileID(fname, fId); 
    declare c1 cursor for select ID, Code, Name from SMSTemplate where F_ID = fId; 
    declare continue handler for not found set SMS_done = true; 
    open c1; 
    SMS_loop : loop

    end loop SMS_loop; 
    select * from FileDetails;

delimiter ; 

，我得到这个错误

ERROR 1064 (42000): 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 'declare c1 cursor for select ID, Code, Name from SMSTemplate where F_ID = fId;' at line 10 

Answer 1

是否表SMSTemplate有场F_ID？

如果没有，那可能是你为什么得到这个错误。

Answer 2

首先获得声明所有组合在一起的顶部。 也没有fetch into这样的东西，所以这两件事是固定的。

Par_don/Par_done在声明中存在拼写错误。

此外，为了理智，如果在每个存储过程的上方存在存储器，则可以放弃，因此它很容易被编写和维护。

drop procedure if exists FileINFO; 
delimiter $$ 
create procedure FileINFO(in fname varchar(100)) 
begin 
    declare SMS_done, Par_done boolean default false; 
    declare SMSID int; 
    declare SMSName varchar(100) default ""; 
    declare SMSCode varchar(100) default ""; 
    declare ParamName varchar(100) default ""; 
    declare fId int; 
    declare c1 cursor for select ID, Code, Name from SMSTemplate where F_ID = fId; 
    declare continue handler for not found set SMS_done = true; 
    call getFileID(fname, fId); 



    open c1; 

    SMS_loop : loop 
     fetch c1 into SMSID, SMSCode, SMSName; 
      if SMS_done then 
       close c1; 
       leave SMS_loop; 
      end if; 
     block2 : begin 
     declare c2 cursor for 
      select Name from ParameterType where ST_ID = SMSID; 
     declare continue handler for not found set Par_done = true; 
     open c2; 
     Par_loop : loop 
      fetch from c2 into ParamName; 
      if SMS_done then 
      set SMS_done = false; 
      close c2; 
      leave Par_loop; 
      end if; 
     insert into FileDetails 
     (FileName, SMSName, SMSCode, ParamName) 
     values 
     (fname, SMSName, SMSCode, ParamName); 
     end loop Par_loop; 
     end block2; 
    end loop SMS_loop; 
    select * from FileDetails;
