求助!!数据库语句

[gongcqj]

数据库中有字段BZ,是这样的形式20033141720（年月日小时分）现在用语句
Adodc1.RecordSource = "select * from tfd where BZ='______?_______'"
窗体中有combo1控件,combo1.text显示的是年如2003
查询符合条件的信息，只要与BZ前四位数相同就显示该信息，语句该怎么写？

如果BZ是字符串型，可以这样写select * from tfd where BZ like '2003%'

[饮水需思源]

"select * from tfd where bz like '"& combo1.text &"%'"
"select * from tfd where left(bz,4)='"& combo1.text &"'"

[DoemingRau]

Adodc1.RecordSource = "select * from tfd where BZ like '"& trim(combo1.text) & "%'"

楼上的几位说的不错，
Adodc1.RecordSource = "select * from tfd where BZ like '2003%'"
