我在delphi 工具SQL Explore中创建一张表:create table "employee1.db"
(name char(10),
empno char(8) ,
dept char(6),
tele char(5) ,
primary key (empno)
)但系统提示:Number is out of range.不知是什么原因?谢谢高手指点!!

(name char(10),
empno char(8) ,
dept char(6),
tele char(5) ,

)
????不太明白
放最前面
create table "employee1.db"
(name char(10),
empno char(8) ,
dept char(6),
tele char(5)
)alter table employee1.db add constraint employee1_empno primary key (empno);
就ok了
create table "employee1.db"
(name char(10),
empno char(8) ,
dept char(6),
tele char(5)
)alter table employee1.db add constraint employee1_empno primary key (empno);
就ok了
