USE [AppStore]
GO

DECLARE @return_value INT

EXEC @return_value = [dbo].[IndianAppStore_Search] @searchparameter = N'wishpicker'

SELECT 'Return Value' = @return_value
GO

在App表的AppName列中，有一行包含wishpicker作为AppName 我想显示这个结果，即使用户只写了搜索查询的愿望。

在sql server中可以使用freetext或任何其他搜索算法吗？

Answer 1

阅读LIKE关键字。但总之......

WHERE (ap.AppName LIKE 'wish%')  -- Finds app names BEGINNING with wish
WHERE (ap.AppName LIKE '%wish%') -- Finds app names CONTAINING wish
WHERE (ap.AppName LIKE '%wish')  -- Finds app names ENDING with wish

Answer 2

添加这个条件怎么样？

OR (@searchparameter = 'wish' and ap.AppName = 'wishpicker')

或者，如果AppName字段需要通配符：

OR (@searchparameter = 'wish' and ap.AppName like '%wishpicker%')
