摘 要:在查询中返回符合指定条件的行记录
正 文:
Function PlusOne(var As Variant)
Static i As Integer
i = i + 1
PlusOne = i
End Function
2、建立一查询,拖出你需要的列,增加一列:
Field Expr1: PlusOne(【MyField】) Mod 5
在总计栏选:Expression
在准则栏输入:0
3、结果将返回所有被5整除的记录

Have a query return every nth record in a table
Author(s)
Erika Yoxall
(Q) How can I write a query to return every fifth record from a table?
(A) Here's a general-purpose way to write a query to return every nth record from a table. It will choose equally-spaced records, but not start in any particular spot, i.e. it might return the 1st, 5th and 9th or 2nd, 6th and 10th records if set to a spacing of 4. First, create a new function:
Function PlusOne (var As Variant)
Static i As Integer
i = i + 1
PlusOne = i
End Function
Then, create your query. Drag down whatever fields you want to see in the output. Add one more column to the query, with these properties:
Field Expr1: PlusOne(【MyField】) Mod 5
Show No
Criteria 0
You can use any field in your output in place of MyField -- it doesn't matter which one you use. If you want every 7th record, use Mod 7, for every 10th record, use Mod 10, and so on.
