I am running a query to delete from table.
delete from sps
inner join str on str.studentid = sps.studentid
where str.studentid like '%2012%psy%'
and str.semesterid=2
inner join papers on papers.id = sps.paperid
where papers.c_id=10
and papers.p_semid=2
I don't know why it is not showing any result and giving me an error.
The error is :
#1064 - You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near
'inner join str on str.studentid=sps.studentid where str.studentid like '%2012%ps'
at line 2
Move the two predicates of the two WHERE clauses into one WHERE clause at the end of your query, as described by the Mysql DELETE syntax. Something like:
DELETE s
FROM sps s
INNER JOIN str ON str.studentid = s.studentid
INNER JOIN papers ON papers.id = s.paperid
WHERE str.studentid LIKE '%2012%psy%'
AND str.semesterid = 2
AND papers.c_id = 10
AND papers.p_semid = 2
You can use WHERE clause once in a single query.
Try this query
DELETE sps FROM sps
INNER JOIN str ON str.studentid=sps.studentid
INNER JOIN papers ON papers.id=sps.paperid
WHERE papers.c_id=10 AND papers.p_semid=2
AND str.studentid LIKE '%2012%psy%' AND str.semesterid=2
OR
DELETE FROM sps, str, papers
USING sps
INNER JOIN str ON str.studentid=sps.studentid
INNER JOIN papers ON papers.id=sps.paperid
WHERE papers.c_id=10
AND papers.p_semid=2
AND str.studentid LIKE '%2012%psy%'
AND str.semesterid=2

I'm very bad at SQL so I'm struggling to UPDATE using values coming from separate tables:
I need use values inside 2 different tables as well as values from PHP script as part of an update query into a third table. with help I was able to make this statement but im getting syntax errors
ou have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'from
order1
join supplier
on supplier.Order_ID = order1.order_ID
join pr' at line 6
My code is here:
update order1
set Reorder_Time=supplier.Reorder_Time,
Amount_Ordered="123456789",
Stock_Amount=product.Stock_Amount,
from order1
join supplier on supplier.Order_ID = order1.order_ID
join production on supplier.Product_ID = product.Product_ID
where orderId = "123456789"
join production on supplier.Product_ID = product.Product_ID
In this line, write to production.Product_Id instead of product.Product_ID.
or you can use,
from order1 o
inner join supplier sp on sp.Order_ID = o.order_ID
inner join production p on sp.Product_ID = p.Product_ID
where orderId = "123456789"`
I would like to update with 2 join.... but :
UPDATE glpi.glpi_users
FROM
glpi.glpi_groups_users
INNER JOIN glpi.glpi_groups ON glpi.glpi_groups_users.groups_id = glpi.glpi_groups.id
INNER JOIN glpi.glpi_users ON glpi.glpi_users.id = glpi.glpi_groups_users.users_id
SET glpi.glpi_users.id = 2
WHERE
glpi.glpi_groups.`name` LIKE 'technique'
1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'FROM
glpi.glpi_groups_users
INNER JOIN glpi.glpi_groups ON glpi.glpi_groups_us' at line 2
Time: 0s
thanks for your help
I think that the syntax you want is:
UPDATE glpi.glpi_users u
INNER JOIN glpi.glpi_groups_users gu ON gu.users_id = u.id
INNER JOIN glpi.glpi_groups g ON g.id = gu.groups_id
SET u.id = 2
WHERE g.name = 'technique'
That is: MySQL update/join syntax doesn't have a FROM clause - it looks like UPDATE ... JOIN ... SET ... WHERE ....
Notes:
since no wildcards do appear in the right side operand, name LIKE 'technique' is equivalent to name = 'technique'
table aliases make the query easier to write and read
Here is the complex query that I wrote but can't figure out what's the problem:
SELECT student.progid,
student.batch
FROM (student
JOIN registers
ON student.studentid = registers.studentid)
JOIN (SELECT offers.courseno
FROM (offers
JOIN instructor
ON offers.instructorid = instructor.instructorid))
ON offers.courseno = registers.courseno
WHERE instructor.instructorname = 'P M Jaat'
AND ( offers.acadyear LIKE '2007%'
OR offers.acadyear LIKE '2008%'
OR offers.acadyear LIKE '2009%'
OR offers.acadyear LIKE '2010%'
OR offers.acadyear LIKE '2011%' );
This results in an error, but I'm going to leave it to others to tell you what that is:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds
to your MySQL server version for the right syntax to use near 'R1
JOIN (SELECT
Double check your parenthesis. Your FROM clause is
(student JOIN registers ON student.StudentID=registers.StudentID)
Which doesn't make sense.
What you want is:
FROM (student)
JOIN registers AS r1
ON (student.StudentID=registers.StudentID)
Or you can just lose the extra parenthesis:
FROM student
JOIN registers AS r1
ON student.StudentID=registers.StudentID
P.S. You also had your AS r1 in the wrong spot.
UPDATE: You need parenthesis when you are using subqueries.
FROM student
JOIN registers
ON student.studentid = registers.studentid
JOIN(
SELECT courseno
FROM offers
JOIN instructor
ON offers.instructorid = instructor.instructorid
) AS r2 ON offers.courseno = registers.courseno
Perhaps you're after something like this...
SELECT r.progid
, r.batch
FROM student s
JOIN registers r
ON r.studentid = s.studentid
JOIN offers o
ON o.courseno = r.courseno
JOIN instructor i
ON i.instructorid = o.instructorid
WHERE i.instructorname = 'P M Jaat'
AND o.acadyear BETWEEN '2007-01-01' AND '2011-12-31';
I have two DBs- RATINGSAPP and MIGRATIONDATA.
I want to update a table in RATINGSAPP with some values in a table in MIGRATIONDATA. I am trying to run this query:
update r set internal_id = m.internal_id from ratingsapp.hotel03 as r
inner join migrationdata.migration as m on r.hotel_id = m.restaurant_id
This gives me error:
You have an error in your SQL syntax;
check the manual that corresponds to your MySQL server version for the right syntax to use near
'from ratingsapp.hotel03 as r inner join migrationdata.migration as m on r.hotel_' at line 1
But a similar select query works for me and gives proper results.
select r.hotel_id, m.internal_id from ratingsapp.hotel03 as r
inner join migrationdata.migration as m on r.hotel_id = m.restaurant_id
What I am doing wrong in the update query?
The correct MySQL syntax is:
update ratingsapp.hotel03 r inner join
migrationdata.migration as m
on r.hotel_id = m.restaurant_id
set internal_id = m.internal_id ;
There is no from clause in a MySQL update. You are using SQL Server/Postgres syntax.
I have following query that is working fine in TSQL
SELECT
shoppingcart_1.price, shoppingcart_1.stid, course.isbn,
book.BookTitle, course.Course_ID, schedule.stid AS Expr1
FROM
book
INNER JOIN
shoppingcart AS shoppingcart_1
INNER JOIN
schedule ON shoppingcart_1.cid = schedule.course_ID
INNER JOIN
course ON schedule.course_ID = course.Course_ID
ON book.isbn = course.isbn
WHERE
(shoppingcart_1.stid = '20070004')
but when I run it in Mysql it displays error on line
INNER JOIN course ON schedule.course_ID = course.Course_ID ON book.isbn = course.isbn
Error text is
1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use
near 'ON book.isbn = course.isbn WHERE (shoppingcart_1.stid =
'20070004') LIMIT 0' at line 6
I am writing queries first time in mysql, please help
Seems like you have your joins a little mixed up. I tried cleaning it up. See if this works for you
SELECT shoppingcart_1.price, shoppingcart_1.stid, course.isbn, book.BookTitle, course.Course_ID, schedule.stid AS Expr1
FROM book
INNER JOIN course ON book.isbn = course.isbn
INNER JOIN schedule ON course.Course_ID = schedule.course_ID
INNER JOIN shoppingcart AS shoppingcart_1 ON schedule.course_ID = shoppingcart_1.cid
WHERE shoppingcart_1.stid = '20070004'
Note how I join book to course, then course to schedule, then schedule to shoppingcart. Then use the WHERE clause to specify other conditions.
