Please don't put duplicate with question IF clause within WHERE clause ?
I think my question is difference, I have been tryed but I can't not run success with condition below.



How can put if condition between where in sql
for example



        SELECT *
FROM LocationOutsw W
WHERE if(@p_type = 'ALL') then
(W.NAME LIKE '%'+ @p_search + '%' OR W.DESCRIPTION LIKE '%'+ @p_search + '%')
if(@p_type == "NAME")
W.NAME LIKE '%'+ @p_search + '%'
if(@p_type == "DESCRIPTION ")
W.DESCRIPTION LIKE '%'+ @p_search + '%')

  • Are you using MySQL, MS SQL Server or Oracle? That query will run on max one of them.

SELECT *
FROM LocationOutsw W
WHERE ( @p_type = 'ALL'
AND ( W.NAME LIKE '%'+ @p_search + '%'
OR W.DESCRIPTION LIKE '%'+ @p_search + '%'
)
)
OR ( @p_type = 'NAME'
AND W.NAME LIKE '%'+ @p_search + '%'
)
OR ( @p_type = 'DESCRIPTION'
AND W.DESCRIPTION LIKE '%'+ @p_search + '%'
)


But I strongly recommend not to write your queries like so, because of wrong query plans you will get.

I would use boolean expressions for this



    SELECT *
FROM LocationOutsw W
WHERE (@p_type = 'ALL' and W.NAME LIKE '%'+ @p_search + '%' OR W.DESCRIPTION LIKE '%'+ @p_search + '%')
or (@p_type = 'NAME' and W.NAME LIKE '%'+ @p_search + '%')
or (@p_type = 'DESCRIPTION' and W.DESCRIPTION LIKE '%'+ @p_search + '%')


Be careful in syntax. Apostrophes have a different meaning than quotation mark.

    SELECT 
    *
    FROM
    LocationOutsw W
    WHERE
    (@p_type = 'ALL' AND
    (W.NAME LIKE '%'+ @p_search + '%' OR W.DESCRIPTION LIKE '%'+ @p_search + '%'))
    OR
    (@p_type = 'NAME' AND W.NAME LIKE '%'+ @p_search + '%')
    OR
    (@p_type = 'DESCRIPTION' AND W.DESCRIPTION LIKE '%'+ @p_search + '%')
