Question

我的内联SQL查询就像这样

DataSet ds =  SqlHelper.ExecuteDataset(GlobalSettings.DbDSN, CommandType.Text, 
   "SELECT TOP 1000 [ID],[Project],[Owner],[Consultant],[Contractor],[Value],
      [Level1], [Level2] ,[Status] ,[Category]  ,[Country],[CreatedDate],
      [CreatedByID], [CreatedByName] 
    FROM [DBname].[dbo].[tbl_Projects] 
    where [Category] like %@Category% 
      and Value=1000 
      and Country like'%Bahrain%' 
    order by CreatedDate",
new SqlParameter("@Category","oil")  );

一切看起来都没问题。但是它会抛出错误

System.Data.SqlClient.SqlException: Incorrect syntax near 'Category'.

我相信使用类似查询时我做错了。任何人都可以指出出了什么问题吗？

Answer 1

我认为这应该有用

... LIKE '%' + @Category + '%'

比照T-SQL and the WHERE LIKE %Parameter% clause

像内联查询中的大小写错误
