求助用存储过程为表循环增加字段??
我写的存储过程如下:
create or replace procedure project_temp as
v_exe_sql varchar2(200);
vnumber number;
gnum number;
begin
begin
gnum :=0;
vnumber :=1;
for vnumber in 1..50 loop
gnum := gnum+1;
begin
v_exe_sql:='alter table temp_ras_project add 偿'||gnum||'number';
execute immediate v_exe_sql;
end;
end loop;
end;
end project_temp;
这个存储过程的用途是为表temp_ras_project增加50个字段不知道存储过程能不能实现,编译没有错误,但是执行就报错了。
请高手给予指点。

v_exe_sql:='alter table temp_ras_project add 偿'||gnum||' number';
execute immediate v_exe_sql;
end;
end loop;
end;
end project_temp;
加个空格
