您是否以错误的方式获得了 Category 和 @Variable:sqlFiddle

Have you got Category and @Variable round the wrong way: sqlFiddle

create table the_table 
(
  category varchar(10),
  [Date] datetime,
  Amount decimal(12, 2)
)

insert into the_table
values
( 'X', '2012-1-1', 10),
( 'X', '2012-1-3', 10),
( 'Y', '2012-1-3', 20),
( 'Y', '2012-1-5', 10)

declare @Variable varchar(10)
set @Variable = 'Y'

Select * 
From the_table 
--Where @Variable Like '%' + category + '%' 
Where category Like '%' + @Variable + '%'
