am i did correct? it is giving correct result but it is taking too long to execute and get results. is there any better way to execute this query only with joins syntax and i don't have access to put index to the table
i have two tables "User" And "UsersSettings" .
and i want to select User's where the users settings is something
what query will be more fast ?
SELECT u.*, us.someSettings FROM User u,UserSettings us
WHERE u.id = us.user_id
AND us.somesettings = somevalue
AND u.someProperty = someOtherValue
AND u.someProperty1 = someOtherValue1
AND u.someProperty2 = someOtherValue2
AND u.someProperty3 = someOtherValue3
AND u.someProperty4 = someOtherValue4
AND us.someUSProperty = someUSvalue
OR
SELECT u.*, us.someSettings FROM User u
LEFT JOIN UserSettings us ON us.user_id = u.id
WHERE us.somesettings = somevalue
AND u.someProperty = someOtherValue
AND u.someProperty1 = someOtherValue1
AND u.someProperty2 = someOtherValue2
AND u.someProperty3 = someOtherValue3
AND u.someProperty4 = someOtherValue4
AND us.someUSProperty = someUSvalue
can you help me please
thank you
The correct query is an inner join:
SELECT u.*, us.someSettings
FROM User u INNER JOIN
UserSettings us
ON us.user_id = u.id
WHERE us.somesettings = somevalue
AND u.someProperty = someOtherValue
AND u.someProperty1 = someOtherValue1
AND u.someProperty2 = someOtherValue2
AND u.someProperty3 = someOtherValue3
AND u.someProperty4 = someOtherValue4
AND us.someUSProperty = someUSvalue;
You have a filtering condition on UserSettings, so the outer join is turned to an inner join anyway. You should avoid implicit join syntax and put the join conditions explicitly in an on clause. This is for readability and maintainability. Both versions should have the same performance.
i have a huge query:
SELECT stories.*
FROM stories stories
JOIN (SELECT tstories.uid
FROM stories tstories
JOIN tours_stories_mm mmt
ON tstories.uid = mmt.uid_foreign
JOIN tours tours
ON tours.uid = mmt.uid_local
JOIN tours_countries_rel tourcountryrel
ON tours.uid = tourcountryrel.tourid
JOIN countries tcountries
ON tcountries.uid = tourcountryrel.countryid
WHERE tcountries.uid = ?
AND tours.deleted = 0
AND tours.hidden = 0
AND tstories.deleted = 0
AND tstories.hidden = 0) as tourstories
JOIN (SELECT cstories.uid
FROM stories cstories
JOIN individualtourcomponents_stories_mm mmc
ON (cstories.uid = mmc.uid_foreign)
JOIN individualtourscomponents components
ON (components.uid = mmc.uid_local)
JOIN individualtourcomponents_countries_rel componentcountryrel
ON (components.uid = componentcountryrel.componentid)
JOIN countries ccountries
ON (ccountries.uid = componentcountryrel.countryid)
WHERE ccountries.uid = ?
AND components.deleted = 0
AND components.hidden = 0
AND cstories.deleted = 0
AND cstories.hidden = 0) as componentstories
WHERE stories.uid = componentstories.uid
OR stories.uid = tourstories.uid
GROUP BY stories.uid`
each of the subqueries work for themselves and if both subqueries have the same result, i get an result on the whole query. If only one subquery has a result i get nothing. Simplyfied it could be written like that:
SELECT stories.*
FROM stories
JOIN (SELECT * FROM table_a WHERE x=5) as table_a
JOIN (SELECT * form table_b where x=5) as table_b
WHERE stories.uid = table_a.uid OR stories.uid = table_b.uid
GROUP BY stories.uid
What am i doing wrong?
It seems like you should be using an OUTER JOIN instead of INNER JOIN to join your source tables.
Using the simplified query example, it might look like this:
SELECT stories.*
FROM stories
LEFT OUTER JOIN (SELECT * FROM table_a WHERE x=5) as table_a
ON stories.uid = table_a.uid
LEFT OUTER JOIN (SELECT * form table_b where x=5) as table_b
ON stories.uid = table_b.uid
GROUP BY stories.uid
UPDATE
Based on your comment it sounds like you actually want to get the distinct union of the the two sub queries.
If that's the case, you could modify your original query like this:
(SELECT tstories.*
FROM stories tstories
JOIN tours_stories_mm mmt
ON tstories.uid = mmt.uid_foreign
JOIN tours tours
ON tours.uid = mmt.uid_local
JOIN tours_countries_rel tourcountryrel
ON tours.uid = tourcountryrel.tourid
JOIN countries tcountries
ON tcountries.uid = tourcountryrel.countryid
WHERE tcountries.uid = ?
AND tours.deleted = 0
AND tours.hidden = 0
AND tstories.deleted = 0
AND tstories.hidden = 0
)
UNION DISTINCT
(SELECT cstories.*
FROM stories cstories
JOIN individualtourcomponents_stories_mm mmc
ON (cstories.uid = mmc.uid_foreign)
JOIN individualtourscomponents components
ON (components.uid = mmc.uid_local)
JOIN individualtourcomponents_countries_rel componentcountryrel
ON (components.uid = componentcountryrel.componentid)
JOIN countries ccountries
ON (ccountries.uid = componentcountryrel.countryid)
WHERE ccountries.uid = ?
AND components.deleted = 0
AND components.hidden = 0
AND cstories.deleted = 0
AND cstories.hidden = 0
)
I need to convert this sql query to linq to sql and the result returns a IEnumerable:
select VisualAidName, v.VisualAidID, vs.VisualAidStatusName,
br.BrandName, v.IsEnabled, v.VisualAidCode, v.DateApproved,
br.BrandID, type, UserFirstName+ ' ' + UserLastName as name, AreaID
from VisualAids v inner join VisualAidStatus vs
on v.VisualAidStatusId = vs.VisualAidStatusId
inner join brands br
on v.BrandID = br.BrandId
inner join VisualAids_Areas_Link vareas
on v.VisualAidID = vareas.VisualAidID
left join users us
on v.Owner = us.UserID
where
AreaID IN (
select areaid
from Users inner join Users_Area_Link
on Users.UserID = Users_Area_Link.UserID
where Users.UserID= 3
)
I did this:
IEnumerable<Visual_Aid> visualAll = from v in Context.VisualAids
join vs in Context.VisualAidStatus on v.VisualAidStatusId equals vs.VisualAidStatusId
join br in Context.Brands on v.BrandID equals br.BrandId
join us in Context.Users on v.Owner equals us.UserID into vadis
from x in vadis.DefaultIfEmpty()
select new Visual_Aid()
{
VisualAid_Name = v.VisualAidName,
VisualAid_Id = v.VisualAidID,
VisualAid_StatusName = vs.VisualAidStatusName,
VisualAid_BrandsName = br.BrandName,
VisualAid_IsEnabled = bool.Parse(v.IsEnabled.ToString()),
VisualAid_Code = v.VisualAidCode,
VisualAid_DateApp = v.DateApproved.ToString() ?? "",
VisualAid_BrandId = int.Parse(v.BrandID.ToString()),
VisualAid_Type = v.Type,
VisualAid_Owner = x.UserID == null ? "" : x.UserFirstName + " " + x.UserLastName
};
but I need to do the part of the subquery, ie, I need to include this:
where AreaID IN (
select areaid from Users inner join Users_Area_Link
on Users.UserID = Users_Area_Link.UserID where Users.UserID= 3
)
Anybody know how? thank you very much in advance
You can add this as a where statement:
.......
join us in Context.Users on v.Owner equals us.UserID into vadis
from x in vadis.DefaultIfEmpty()
where (
from user in Context.Users
join userArea in Users_Area_Link
on user.UserID equals userArea.UserID
where user.UserID==3
select userArea.areaid
).Contains(????.AreaID)
select new Visual_Aid()
{
.......
