＆＃34;查询表达式中的语法错误（缺少运算符）＆＃39;学生ID如   15001＆＃39;

Answer 1

如果真的在学生和ID tehn之间有空格，那么您的查询必须是：

sql = "update Attendance set Attended=Attended+1 where [Student ID] like 15001"
db.Execute (sql)

Answer 2

sql应该始终用_写。例如，学生ID应始终为Student_ID，以便它能够读取筛选其搜索所需的列。为了将来的目的，始终使用_创建列名。

sql = "update Attendance set Attended=Attended+1 where Student_ID like 15001"
db.Execute (sql)

或

sql = "update Attendance set Attended=Attended+1 where [Student ID] like 15001"
db.Execute (sql)

Answer 3

尝试一些看起来更清洁的东西......

sql = "Update tblAttendance SET "
sql = sql & " Attended = Attended + 1 "
sql = sql & " Where Student_ID = 15001 "
db.execute SQL <-- no paranthesis
