SELECT
(select Email from Contact where AccountId = Account.Id),
Id,
BillingCity,
BillingCountry,
BillingPostalCode,
BillingState,
BillingStreet,
Name,
Phone
FROM Account
where
LastModifiedDate < #[flowVars['timestamp']]
Problem here is I am not able to get the Email which is present in the sub query based on the Id of current iteration. Can you please help on this
I'm not sure how you are running the query, and how you are accessing the result, but if you are doing it in a place that does not give you the result dynamically, meaning that you try to access the columns by expected name, i.e. trying to get the "email" column somehow, then you need to fix a small issue in the query.
You need to add the AS operator to give your subquery a meaningful name like email like so:
...
(select Email from Contact where AccountId = Account.Id) as email,
...
See fiddle here for working example: db-fiddle
You can get rid of the scalar sub-query and just put a join to the CONTACT table instead. The following assumes that the CONTACT table is an optional relationship.
SELECT
con.email,
acct.Id,
acct.BillingCity,
acct.BillingCountry,
acct.BillingPostalCode,
acct.BillingState,
acct.BillingStreet,
acct.Name,
acct.Phone
FROM account acct
LEFT OUTER JOIN
contact con ON con.account_id = acct.account_id
WHERE acct.LastModifiedDate < #[flowVars['timestamp']]

We have three table
table 1- app ( id , name )
table 2- appPlayer ( id , name )
table 3- appPlayerSession ( id , appId , appPlayerId , version)
my Current query is:
SELECT (select name from app k where k.id= aps.appId) AS appName,version,appId,count(version) FROM appPlayerSession aps GROUP BY appId,version,appName
we need to count the session users for each game with same version, and also woth the object of all users data using single mysql query.
Current Result using my query, but we also need players for each app..
As you havent given your expected result and on basis of your requirement you can do something this.it may be enhanced as per your requirement.
SELECT (select name from app k where k.id= aps.appId) AS appName,version,appId,(select P.name from appPlayer P where P.id=aps.appPlayerid) as appPlayerName, count(version) FROM appPlayerSession aps GROUP BY appId,version,appName,appPlayerName
Also check fiddle as per your requirement created as you havent given any data set and its on my assumption.

New Sql as per your new added requirement-
select X.appname,X.version,X.appid,GROUP_CONCAT(distinct X.appPlayerName order by X.appPlayerName) as Users ,
sum(X.vercount)
from (SELECT (select name from app k where k.id= aps.appId)
AS appName,version,appId,
(select P.name from appPlayer P where P.id=aps.appPlayerid)
as appPlayerName, count(version)as vercount
FROM appPlayerSession aps
GROUP BY appId,version,appName,appPlayerName) X
group by X.appname,X.version,X.appid

You can use JOIN in sql to connect with multiple tables and fetch result
Below is the format :
SELECT t1.col,
t3.col
FROM table1
JOIN table2
ON table1.primarykey = table2.foreignkey
JOIN table3
ON table2.primarykey = table3.foreignkey
In your case :
SELECT app.col,
appPlayer.col,
appPlayerSession.col
FROM app
JOIN appPlayer
ON app.id = appPlayer.appId
JOIN appPlayerSession
ON appPlayer.id = appPlayerSession.appPlayerId
Hope this is helpful.
One suggestion . It is not a standard to use camelCase for table and column names. snake_case is preferred widely.
Okay so, this is my query.
select id from rooms where owner = 'oknow';
and the answer I get is
325
However, I made another SQL within this one as below
update users set home_room = 'mysql_fetch_assoc()' where username = 'omarisgod';
I want the 'mysql_fetchassoc()' to be the '325' value, how do I do this?
A subquery will do this:
UPDATE users SET home_room = (SELECT id FROM rooms WHERE owner = 'oknow') WHERE username = 'omarisgod';
You can conceptualize it thusly: The query inside parentheses will return a result, which will be utilized by the outer query.
Say I have the following tables
User
__________
id
username
email
FriendGame
__________
id
useroneid
usertwoid
status
I want to get games that the current user is part of, so I do this:
SELECT *
FROM FriendGame
WHERE useroneid=1663702020516206
OR usertwoid=1663702020516206
AND STATUS =1;
This is fine. Now I want to join the username, but only for the user that ISNT the supplied user (1663702020516206) since in FriendGame the given user exists EITHER as useroneid or usertwoid.
You can pretty much translate your logic directly into an on clause:
SELECT fg.*
FROM FriendGame fg JOIN
User u
ON (fg.useroneid = 1663702020516206 and fg.usertwoid = u.id) or
(fg.usertwoid = 1663702020516206 and fg.useroneid = u.id)
WHERE 1663702020516206 in (fg.useroneid, fg.usertwoid) AND
STATUS = 1;
Actually, the where clause is not necessary to get the right result set, but I think it makes the intention of the query clearer.
I got the following sql question that I that won´t work for me. I know that the last CASE row are wrong but I would like to use a CASE statement like that in my where clause.
Short description of my situation:
I got several companies that got there own material linked to them with "companyID". Each material might be linked to a row in pricelist_entries. If I search for one row in the pricelist_entries table that is linked to many material rows all rows will be returned but I just want to return the one that belongs to the current company (the company that performs the search).
Conclusion: If materialID NOT NULL THEN materials.company="current.companyID".
SELECT peID, peName, materialID
FROM pricelist_entries
INNER JOIN pricelist ON pricelist_entries.peParentID=pricelist.pID
LEFT JOIN materials ON pricelist_entries.peID=materials.pricelist_entries_id
WHERE peBrand = 'Kama' AND pricelist.pCurrent = 1
AND (peName LIKE '%gocamp de%' OR peArtnr LIKE '%gocamp de%')
AND pricelist.country=0 AND pricelist_entries.peDeleted=0
CASE materialID WHEN IS NOT NULL THEN materials.companyID=10 END
Please tell me if I need to describe my problem in a better way.
Thanks in advance!
Sounds like just moving the condition into the join would make it simpler;
SELECT peID, peName, materialID
FROM pricelist_entries
INNER JOIN pricelist
ON pricelist_entries.peParentID=pricelist.pID
LEFT JOIN materials
ON pricelist_entries.peID=materials.pricelist_entries_id
AND materials.companyID=10 -- << condition
WHERE peBrand = 'Kama' AND pricelist.pCurrent = 1
AND (peName LIKE '%gocamp de%' OR peArtnr LIKE '%gocamp de%')
AND pricelist.country=0 AND pricelist_entries.peDeleted=0
It will only left join in material rows that are linked to the correct company.
You can't use CASE in the where clause that I'm aware of, you need to use it in the SELECT portion, but it will have the same effect. Something like this should work:
SELECT CASE materialid WHEN IS NOT NULL THEN companyid END as thiscompanyid
This will give you a new column named thiscompanyid and you can query off of that to get what you need.
I currently have a search form which should allow a user to search for a customers full name and it will return the row.
For Example: A user searches for "Mr. N Mallow" and it will return the row which matches that query. Since I am new to MySQL I need some help, I've tried + but that has no effect, probably because it's not standard mysql or something like that.
select *
from mooring
left join customer
on mooring.assignedTo = customer.id
where mooring.Number like \"$var\"
or (customer.TitleName + customer.Surname = '$var')
Any suggestions?
select * from mooring
left join customer on mooring.assignedTo = customer.id
where mooring.Number like \"$var\" OR (customer.TitleName + customer.Surname = '$var')
Try CONCAT_WS or CONCAT, which join strings together (the first version is "with separator"):
CONCAT(customer.TitleName,' ',customer.Surname)
or
CONCAT_WS(' ',customer.TitleName,customer.Surname)
