1.所有的and前应该加个空格,否则会和上面的语句拼在一起
比如
sqlstr+="and fileTitle='"%+TB_title.Text%"'";
应该修改为
sqlstr+=" and fileTitle='"%+TB_title.Text%"'";
2.时间这里处理有问题,变量不能包括在双引号里面
if(CB_date.Selected)
{
DateTime startDate=(DateTime)"'"+TB_dateMin.Text+"'";
DateTime endDate=(DateTime)"'"+TB_dateMax.Text+"'";
startDate.ToString("yyyy-mm-dd",DateTimeFormatInfo.InvariantInfo);
starDate.ToString("yyyy-mm-dd",DateTimeFormatInfo.InvariantInfo);
sqlstr+="and reciveDate='"convert(varchar(10),reciveDate,120) between startDate and endDate"'";
}
可以修改为
if(CB_date.Selected)
{
sqlstr+= string.Format(" and reciveDate between '{0}' and '{1}'",TB_dateMin.Text,TB_dateMax.Text);
}
