MS Access数据库分页+搜索怎么办? [英] How to do MS Access database paging + search?

问题描述

我有一个MS Access 2003数据库，该数据库的表名为product1，主表名为Product Code.没有自动ID列.

I have a MS Access 2003 database with a table called product1 with a Primary key named Product Code. There is no auto id column.

我已使用此sql进行自定义数据分页.

I have used this sql to do the custom data paging.

 SELECT *
FROM (
  SELECT Top 1  -- = PageSize
  *
  FROM
  (
   SELECT TOP 1  -- = StartPos + PageSize
   *
   FROM product1
   ORDER BY product1.[Product Code]
  ) AS sub1
  ORDER BY sub1.[Product Code] DESC
 ) AS clients
ORDER BY [Product Code]

现在我的问题是搜索.当我在数据库表上搜索某些内容并指向它时.

Now my problem is Search. When I search for something on the database table and point it.

如何确保仍能正常进行分页?

How can I make sure still paging works fine?

推荐答案

我也正在通过C#查询Access(具有分页和搜索功能)，并且正在使用以下代码构建所有查询:

I'm querying Access from C# as well (with paging and searching), and I'm using the following code to build all my queries:

var sb = new StringBuilder();
sb.Append("select {0} from {1}");
sb.Append(" where {3} in (");
sb.Append("select top {4} sub.{3}");
sb.Append("    from (");
sb.Append("          select top {5} tab.{3}");
sb.Append("          from {1} tab");
sb.Append("          where {2}");
sb.Append("          order by tab.{3}");
sb.Append("    ) sub");
sb.Append("    order by sub.{3} desc");
sb.Append(")");
sb.Append("order by {3}");

sql = string.Format(sb.ToString(), this.ColumnsToSelect, this.TableName, 
    this.WhereClause, this.OrderBy, this.PageSize, this.PageNum * this.PageSize);

请注意，要使其正常工作，必须提供所有参数
(如果您实际上不想过滤任何内容，只需将1=1放在WHERE子句中)

Note that in order for this to work, all parameters must be supplied
(if you don't actually want to filter anything, just put 1=1 into the WHERE clause)
