如何解决以下问题 [英] How to solve following problem

问题描述

declare @vc_supplier_name varchar(200) =''
declare @in_supplier_type_id int =2
declare @bt_active bit

SELECT a.in_supplier_id, dbo.format_fnc_bit(1, a.bt_active) AS vc_active, b.vc_supplier_type_name, a.in_supplier_type_id, a.vc_supplier_name,

    dbo.admin_user_fnc_get_name(1, a.in_updatedby_user_id) AS vc_updated_by, a.dt_updated

    FROM dbo.supplier a

    INNER JOIN dbo.common_data_vw_supplier_type b ON a.in_supplier_type_id = b.in_supplier_type_id

    WHERE a.in_supplier_type_id = @in_supplier_type_id AND a.vc_supplier_name LIKE '%' + @vc_supplier_name + '%'
    AND  if(@bt_active <> '') a.bt_active= @bt_active
    ORDER BY a.vc_supplier_name

这里我从aps.net页面传递bt_active ..所以我想检查一下如果bt_active传递为1那么它应该用Active Record过滤掉其他所有记录都应显示

Here I pass bt_active from aps.net page .. So i want to check that if bt_active is passes as 1 then it should filter with Active record else all record should display

推荐答案

最简单的方法是：

The simplest approach is this:

AND (@bt_active = 0 OR a.bt_active=1)

如果 @bt_active 变量和 a.bt_active 字段只能存储 0 和 1 ，当0表示非活动时并且1表示活动，您需要构建查询取决于此变量：

If @bt_active variable and a.bt_active field can stores only 0 and 1, when 0 means non-active and 1 means active, you need to build query depends on this variable:

IF @bt_active = 1 
BEGIN
    --query to get active records
ELSE
    --query to get all records
END
