运行时错误“ 13”：SQL代码中的类型不匹配

当我评估您的表达式时，它返回FALSE，这肯定是导致不匹配错误的原因，因为SQL需要一个字符串查询。

问题出在您最初的串联方法中，这是错误地组合了两件事。

如果您想做：

Sql = Sql & " some expression"
Sql = Sql & " some other expression"
'Etc.

需要注意的是在上面的，我也不要继续行了，像你这样：

Sql = Sql & " some expression" & _
Sql = Sql & " some other expression" 

那会引发一个错误。因此可视化它：

Sql = Sql & " A " & Sql = Sql & " B "

或者：

Sql = ((Sql & " A " & Sql) = (Sql & " B "))

错误的产生是因为该表达式在逻辑上求和False：该赋值语句的右侧是一个等效语句，并且由于等效语句中的两个表达式不相等，因此只能返回FALSE。

除了纠正对行继续字符的滥用以外，我没有对查询表达式进行任何更改：
