Question

这是我的2个参数查询。有人可以帮助我吗？

sql = "select * 
       from studentlist 
       where firstname like '%" 
     & Transaction.SEARCHSTUDENT.Text 
     & "%' or studentnum like '%" 
     & Transaction.SEARCHSTUDENT.Text 
     & "%' and not in (select studentnum from borrowing of books where status ='borrowed')"

Answer 1

如果borrowing of books是您的表名（带有空格），则应该用反引号括起来，如下所示：

`borrowing of books`

编辑：此外，看起来你的where子句中缺少studentnum，所以它应该看起来像这样：

sql = "select * 
   from studentlist 
   where (firstname like '%" 
 & Transaction.SEARCHSTUDENT.Text 
 & "%' or studentnum like '%" 
 & Transaction.SEARCHSTUDENT.Text 
 & "%') and studentnum not in (select studentnum from `borrowing of books` where status ='borrowed')"

两个表之间的查询
