I'm trying to update records through a single inner join with multiple criteria. My best effort so far is this:
UPDATE FormData d
INNER JOIN ProductGrowthDays g
ON d.ProductCode = g.ProductCode AND
ON d.ProductionLineCode = g.ProductionLineCode AND
ON g.MonthIndex = MONTH(d.SowingDate)
SET d.EstimatedDays = g.GrowingDays
WHERE
d.EventTypeId = 1
Access gives the error 'Syntax error (missing operator)' and highlights the 'r' in 'd.ProductCode'. The join is guaranteed to give a single row.
Could anyone give me pointers on how to fix this?
D'oh. The answer was as follows:
UPDATE FormData d
INNER JOIN ProductGrowthDays g
ON (d.ProductCode = g.ProductCode
AND d.ProductionLineCode = g.ProductionLineCode
AND g.MonthIndex = MONTH(d.SowingDate))
SET d.EstimatedDays = g.GrowingDays
WHERE
d.EventTypeId = 1
I was sure I tried that at one point, but obviously not. Well, leaving this here if someone else should need it.

SELECT
i.*,
ii.file_location
FROM group_shop_item i, group_shop_itemimage ii, group_shop_brand b
WHERE
i.brand_id = b.id
AND
b.brand_status_id = 1
AND
i.is_deleted = 0
AND
i.is_displayed = 1
AND
i.id = ii.item_id
AND
ii.is_main = 1
AND
i.deal_participate = 1
AND
i.brand_label_id IS NOT NULL
ORDER BY i.datetime_modified DESC;
This SQL query keeps throwing me a 1064. It seems to be on the last line which I've tried with and without the i table variable. I can't for the life of me catch the error, anyone can lend me another pair of eyes?
I'm throwing this as a RAW query into the in built Django function and building this query with string concatenation. This copy paste is directly from a print I've done from the command line. It's outputting neatly but isn't reading when I run the view on my browser.
Over 25 years ago ANSI Standard join syntax was adopted. You need to cease using comas between table names in the from clause.
SELECT
i.*
, ii.file_location
FROM group_shop_item i
INNER JOIN group_shop_itemimage ii ON i.id = ii.item_id
INNER JOIN group_shop_brand b ON i.brand_id = b.id
WHERE i.is_deleted = 0
AND i.is_displayed = 1
AND ii.is_main = 1
AND i.deal_participate = 1
AND i.brand_label_id IS NOT NULL
AND b.brand_status_id = 1
;
Regarding the 1064 error, please read this without the exact error message and the exact/full query we can't offer much insight into that.
The other thing you need to be careful of is that "select *" isn't good practice either.
I had a query which was working just fine:
#schedule = Schedule.find(params[:id])
#schedule_tasks = ScheduleTask.select("s.*, t.*, t.*, d.*, st.*").from("schedule_tasks st").
joins("left join schedules s ON s.id = st.schedule_id").
joins("left join tasks t ON t.id = st.task_id").
joins("right join days d ON d.id = st.day_id").
order("d.number, t.name").
group_by{|d| d.number}
I had to refine my search to only schedule_tasks with a specific schedule_id, so I edited the second line to:
joins("left join schedules s ON s.id = st.schedule_id AND s.id = ?", #schedule.id).
This has cause the following error:
unknown class: Fixnum
The error goes away if I take out the group_by - but I need that, and I have tried hard coding in the number instead of #schedule.id and that does not work either, a google search does not reveal a lot of details on this error.
For anyone coming here from Google, I used plain string interpolation to fix this issue. This method is vulnerable to SQL Injection, so make sure you type check your variables before using them.
In this case I would do
#schedule_id = #schedule.id
.
.
.
joins("left join schedules s ON s.id = st.schedule_id AND s.id = #{#schedule_id}")
Rather than following learning_to_swim's answer, which as noted is at risk of SQL injection, couldn't you cast your #schedule_id to a string?
#tasks = ScheduleTask.joins("left join [...] s.id = ?", #schedule.id.to_s)
I'm facing a problem and I'm not finding the answer. I'm querying a MySql table during my java process and I would like to exclude some rows from the return of my query.
Here is the query:
SELECT
o.offer_id,
o.external_cat,
o.cat,
o.shop,
o.item_id,
oa.value
FROM
offer AS o,
offerattributes AS oa
WHERE
o.offer_id = oa.offer_id
AND (cat = 1200000 OR cat = 12050200
OR cat = 13020304
OR cat = 3041400
OR cat = 3041402)
AND (oa.attribute_id = 'status_live_unattached_pregen'
OR oa.attribute_id = 'status_live_attached_pregen'
OR oa.attribute_id = 'status_dead_offer_getter'
OR oa.attribute_id = 'most_recent_status')
AND (oa.value = 'OK'
OR oa.value='status_live_unattached_pregen'
OR oa.value='status_live_attached_pregen'
OR oa.value='status_dead_offer_getter')
The trick here is that I need the value to be 'OK' in order to continue my process but I don't need mysql to return it in its response, I only need the other values to be returned, for the moment its returning two rows by query, one with the 'OK' value and another with one of the other values.
I would like the return value to be like this:
'000005261383370', '10020578', '1200000', '562', '1000000_157795705', 'status_live_attached_pregen'
for my query, but it returns:
'000005261383370', '10020578', '1200000', '562', '1000000_157795705', 'OK'
'000005261383370', '10020578', '1200000', '562', '1000000_157795705', 'status_live_attached_pregen'
Some help would really be appreciated.
Thank you !
You can solve this with an INNER JOIN on the self I think:
SELECT o.offer_id
,o.external_cat
,o.cat
,o.shop
,o.item_id
,oa.value
FROM offer AS o
INNER JOIN offerattributes AS oa
ON o.offer_id = oa.offer_id
INNER JOIN offerattributes AS oaOK
ON oaOK.offer_id = oa.offer_id
AND oaOK.value = 'OK'
WHERE o.cat IN (1200000,12050200,13020304,3041400,3041402)
AND oa.attribute_id IN ('status_live_unattached_pregen','status_live_attached_pregen','status_dead_offer_getter','most_recent_status')
AND oa.value IN ('status_live_unattached_pregen','status_live_attached_pregen','status_dead_offer_getter');
By doing a self-JOIN with the restriction of value OK, it will limit the result set to offer_ids that have an OK response, but the WHERE clause will still retrieve the values you need. Based on your description, I think this is what you were looking for.
I also converted your implicit cross JOIN to an explicit INNER JOIN, as well as changed your ORs to IN, should be more performant this way.
I have created a table and need to update the entries by comparing the data from the view that I have created in SQL server
This action need to performed by a button click in MS Access forms
I have written the following query in MS Access - Query. Exported the view totaltemp1 from sql server.
update P_Payroll as p
inner join totaltemp1 as tp on p.emp_id = tp.emp_id
inner join P_Student_Supervisor as ss on tp.emp_id = ss.emp_id
set Number_of_Hours = tp.temp_drop_hours,
Total_Payment = tp.temp_drop_hours*ss.emp_hourlywage
where p.emp_id = tp.emp_id and ss.emp_id = p.emp_id;
Previously I got this working correctly in SQL server in stand alone mode. Code for that as follows.
update P_Payroll set Number_of_Hours = tp.temp_drop_hours, Total_Payment = tp.temp_drop_hours*ss.emp_hourlywage
from totaltemp1 as tp, P_Payroll as p, P_Student_Supervisor as ss
where p.emp_id = tp.emp_id and ss.emp_id = p.emp_id;
I have checked the data structure too. I am just getting an error
"Syntax error (missing operator) in query expression 'p.emp_id = tp.emp_id inner join P_Student_Supervisor as ss on tp.emp_id = ss.emp_i"
Thanks for your time
Pk.
Two things you can check... first, remove the WHERE clause - you're already specifying those conditions in the JOIN statements.
Then, put brackets around your joins...
UPDATE (P_Payroll AS p
INNER JOIN totaltemp1 AS tp on p.emp_id = tp.emp_id)
INNER JOIN P_Student_Supervisor AS ss on tp.emp_id = ss.emp_id
SET p.Number_of_Hours = tp.temp_drop_hours,
p.Total_Payment = tp.temp_drop_hours * ss.emp_hourlywage
Access like brackets...
I have had a read through a few of the other issues around joining on SQL Updates but haven't been able to finalise a query.
System is all in MySQL (INNODB table structure)
We are wanting to update an amount in one table that will increase an amount based on 2 variables from another table. There are a few constraints that need to be checked in the update to make sure the variables from the second table match the keys in the table to be updated
UPDATE as1
SET as1.amount = as1.amount + (b1.workers * b1.level)
FROM account_stock AS as1
INNER JOIN building AS b1 ON as1.accountID = b1.accountID
INNER JOIN building_seed AS bs1 ON bs1.buildingID = b1.buildingID
WHERE bs1.stockID = as1.stockID
AND b1.accountID = as1.accountID
AND b1.locID = as1.locID
AND b1.status = active
AND b1.gTime > 0
It's getting an error and I can't pick it. Sorry if it is a simple question, all my SQL is self taught so some of the habits I have aren't very good!
MySQL syntax for UPDATE is different. There is no FROM:
UPDATE
account_stock AS as1
INNER JOIN building AS b1 ON as1.accountID = b1.accountID
INNER JOIN building_seed AS bs1 ON bs1.buildingID = b1.buildingID
SET as1.amount = as1.amount + (b1.workers * b1.level)
WHERE bs1.stockID = as1.stockID
AND b1.locID = as1.locID
AND b1.status = active
AND b1.gTime > 0 ;
--- removed duplicate :
--- AND b1.accountID = as1.accountID
Also: is active a column or you meant to write?: AND b1.status = 'active'
