在我們做搜索的時(shí)候經(jīng)常要用到模糊查詢
(注:其中name1,name2,name3,name4為數(shù)據(jù)庫(kù)字段)
1.方法
復(fù)制代碼 代碼如下:
sql="select * from table where "
if name>"" then
sql=sql "name1='"變量"'"
end if
if belong1>"" then
sql=sql "name2='"變量"'"
end if
if belong2>"" then
sql=sql "name3='"變量"'"
end if
if belong3>"" then
sql=sql "name4='"變量"'"
end if
2.方法(存儲(chǔ)過(guò)程)
復(fù)制代碼 代碼如下:
create proc spyourname
(
@name1 varchar(20),
@name2 varchar(20),
@name3 varchar(20),
@name4 varchar(20),
@name5 varchar(20)
)
WITH ENCRYPTION
as
set nocount on
declare @SQL varchar(5000)
set @SQL='select name1,name2,name3,name4,name5 from yourtable where 1=1 '
if @name>''
set @SQL=@SQL+ ' and name1 like ''%'+@name+'%'''
if @belong1>''
set @SQL=@SQL+ ' and name2 like ''%'+@belong1+'%'''
if @belong2>''
set @SQL=@SQL+ ' and name3 like ''%'+@belong2+'%'''
if @belong3>''
set @SQL=@SQL+ ' and name4 like ''%'+@belong3+'%'''
exec(@SQL)
