mysql - SQL:使用where来搜索带有参数的当前查询

Question

这是我的想法:

DECLARE @Search varchar(150)
SET @Search = 'CompanyName'

SELECT a, b, c, d, e
FROM Table
WHERE a, b, c, d, e in (@Search)

这可能吗？如果可以，where条件是否可以设置为:

WHERE a, b, c, d, e in (('%')+(@Search))

这样它会根据搜索搜索所有连接？？

Answer 1

这会起作用!

DECLARE @Search varchar(150)
SET @Search = 'CompanyName'

SELECT a, b, c, d, e
FROM Table
WHERE a = @Search or 
      b = @Search or 
      c = @Search or 
      d = @Search or 
      e = @Search


 SELECT a, b, c, d, e
    FROM Table
    WHERE a like '%' +  @Search + '%' or 
          b like '%' + @Search + '%' or 
          c like '%' + @Search + '%' or 
          d like '%' + @Search + '%' or 
          e like '%' + @Search + '%'
