The statement is too long or too complex ?

Hello,

I'm getting this error while trying to build the stored procedure :

create procedure sp_X_AccountDoc(in nDocID integer)
begin
declare szFuncName varchar(255);
declare nfID integer;
declare nShapeID integer;
declare buff varchar(350);
DECLARE at_end SMALLINT DEFAULT 0;
DECLARE not_found CONDITION FOR SQLSTATE '02000';
declare cur cursor for select f.Name,f.id,dtf.ShapeID from
Z_Documents as d join Z_Documents_Types as t on t.id = d.typeid join X_Shapes_To_DocTypes as dtf on dtf.doctypeid = t.id join
S_AccFunctions as f on f.id = dtf.funcid where
d.ID = nDocID;
DECLARE CONTINUE HANDLER for not_found SET AT_END = 1;
open cur;
fetch from cur into szFuncName,nfID,nShapeID;
FLoop: loop
IF at_end <> 0 then
leave FLoop;
end if;
set buff = 'call '||szFuncName||'('||char(nDocID)||','||char(nShape ID)||')';
execute immediate buff;
fetch from cur into szFuncName,
nFID,
nShapeID;
end loop FLoop;
close cur;
end

Why would the compiler think it is too complex ?

Thanks
