MySQL的VARCHAR字段的问题
mysql中的varchar字段,为什么插入00555的记录时,表中存储的是555!怎么保证必须是00555呢?

------解决方案--------------------
`varcharfield`= '00555 '

值为00555的变量注意不要是整型
------解决方案--------------------
'00555 '
------解决方案--------------------
引号...
------解决方案--------------------
是啊,千万不要这么赋值啊:
insert into(myvarchar) values(00555)
而是这样:
insert into(myvarchar) values( '00555 ')

------解决方案--------------------
按字符串插入数据,就不会存在你说的情况。
------解决方案--------------------
应该是你在插入的时候没加引号,所以当成int来处理了.
------解决方案--------------------
同意,是这问题
