查询匹配列表SQL Server中的所有记录

Question

I have a table bawe_services. i want to fetch all data that match with given keys

like i have fields

id  | Service_id |bawe_id
1       2          2
2       3          3
3       2          3

if i pass service =2 i need all record of service_id=2 if i pass service=1,2,3 than i want 0 rows because 1 service is not given by any bawe so. i got 0 rows.

I use this query

select * from aspnet_bawe_services where ser_id in(1,2,3)

Thanx in advance

Answer 1

The count of the parameters in the "in" statement must match the having equal number.

select bawe_id from [dbo].[aspnet_bawe_services]
where Service_id in (2)
group by bawe_id
having count(Service_id)=1;

bawe_id
-----------
2
3

select bawe_id from [dbo].[aspnet_bawe_services]
where Service_id in (2,3)
group by bawe_id
having count(Service_id)=2;

bawe_id
-----------
3

select bawe_id from [dbo].[aspnet_bawe_services]
where Service_id in (1,2,3)
group by bawe_id
having count(Service_id)=3;

bawe_id
-----------

(0 row(s) affected)

Answer 2

TRY THIS : It's really tedious but unique requirement and I think to accomplish this, we have to use function

1-Function returns distinct count of service_id

2-Function to split comma separated value and return in table format

--Function returns distinct count of service_id

CREATE FUNCTION [dbo].[getCount](@service_id varchar(500))
RETURNS INT             
AS       
BEGIN   
    DECLARE @count int   

    SELECT @count = COUNT(DISTINCT(t.service_id))
    FROM tmptos t
    INNER JOIN [dbo].[SplitValue](@service_id, ',') tt on t.service_id = tt.items

RETURN @count
END;

--Function to split comma separated value and return in table format --Function copied from -- separate comma separated values and store in table in sql server

CREATE FUNCTION [dbo].[SplitValue](@String varchar(MAX), @Delimiter char(1))       
RETURNS @temptable TABLE (items VARCHAR(MAX))       
AS       
BEGIN      
    DECLARE @idx int       
    DECLARE @slice varchar(8000)       

    SELECT @idx = 1       
        if len(@String)<1 or @String is null  return       

    WHILE @idx!= 0       
    BEGIN       
        set @idx = charindex(@Delimiter,@String)       
        IF @idx!=0       
            set @slice = left(@String,@idx - 1)       
        else       
            set @slice = @String       

        IF(LEN(@slice)>0)  
            INSERT INTO @temptable(Items) values(@slice)       

        SET @String = right(@String,len(@String) - @idx)       
        IF LEN(@String) = 0 break       
    END   
RETURN 
END;

--Table with Sample Data

create table tmptos(id int, Service_id int, bawe_id int)
insert into tmptos values
(1,       2,          2),
(2,       3,         3),
(3,       2,          3)


declare @service_id varchar(50) = '2,3'

select *
from tmptos t
inner join [dbo].[SplitValue](@service_id, ',') tt on t.Service_id = tt.items
where [dbo].[getCount](@service_id) = (select count(distinct(items)) from [dbo].[SplitValue](@service_id, ','))

OUTPUT:

id  Service_id  bawe_id items
1   2           2       2
2   3           3       3
3   2           3       2

It's bit lengthy but works perfectly.

Answer 3

select * from aspnet_bawe_services 
where Service_id  in (1,2,3) 
and 
( select count(distinct Service_id) from aspnet_bawe_services where Service_id  in (1,2,3) ) = 3

last number in query (in this case "3") is elements count, which you have in IN list.

Answer 4

You can get the service ids that you want using group by and having :

select service_id
from t
where bawe_id in (1, 2, 3)
group by service_id
having count(distinct bawe_id) = 3;

The "= 3" is the number of ids in the IN list.

You can then use in or join or exists to get the full records:

select t.*
from t
where t.service_id in (select service_id
                       from t
                       where bawe_id in (1, 2, 3)
                       group by service_id
                       having count(distinct bawe_id) = 3
                      );
