I have the following query :
select irc.*,p.*,#product :='prod_product',#accessrole :='pub_accessrole'
from item_rel_coupon irc
join user_rel_coupon urc on urc.userId = 7 and irc.couponId=urc.couponId
left join if(irc.source='product',#product,#accessrole) as p on p.id=irc.itemId
But I get a syntax error. Why?
Nanne is right, your IF() is not a table. There are two ways around:
You join on both tables, and put the
IF in your select to select the
columns from the table you want.
(recommended)
You use the IF to create the query
in a string, you PREPARE the string
and EXECUTE the handle. (not
recommended)
This part gives an error:1
left join if(irc.source='product',#product,#accessrole) as p on p.id=irc.itemId
I after a JOIN you need a table reference, and I don't think your if 's result is one.
1: the error:
#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 'if(irc.source='product',#product,#accessrole) as p on p.id=irc.itemId LIMIT 0,' at line 1
I don't think I've ever seen an IF() used as a table reference in a query, especially if the IRC source can alternate between different sources... I would change to...
select
irc.*,
if( p1.id = irc.itemid, p1.fld1, p2.fld1 ) as Fld1,
if( p1.id = irc.itemid, p1.fld2, p2.fld2 ) as Fld2,
if( p1.id = irc.itemid, p1.fld3, p2.fld3 ) as Fld3,
if( p1.id = irc.itemid, p1.fld4, p2.fld4 ) as Fld4
from
item_rel_coupon irc
join user_rel_coupon urc
on urc.userId = 7
and irc.couponId=urc.couponId
left join prod_product p1
on p1.id = irc.itemid
left join pub_accessrole p2
on p2.id = irc.itemid

I have a query that works perfectly, however I need to change it a bit but it shows me an error and I can't figure out why. Below is the code before and after the changes I made:
BEFORE:
SELECT *,
(SELECT GROUP_CONCAT(pho_file_name) FROM post_images WHERE pho_post_id=posts.ID) AS photo_file_array
FROM users
INNER JOIN posts ON users.Id = posts.post_author
ORDER BY posts.ID;
AFTER:
SELECT *,
(SELECT GROUP_CONCAT(pho_file_name) FROM post_images WHERE pho_post_id=posts.ID) AS photo_file_array
FROM users WHERE users.Id = "1"
INNER JOIN posts ON users.Id = posts.post_author ON posts.post_date = "2020-12-04 07:51:21"
ORDER BY posts.ID;
It shows me the following error:
#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 'INNER JOIN posts ON users.Id = posts.post_author AND posts.post_date "2020-12...' at line 4
I'm a newbie on MySql but from what I can understand I think the error occurs because of the the double ON inside the INNER JOIN. So, is it possible to add multiple ON inside the INNER JOIN? Thanks in advance!!
You have a few syntax issues, you can't put joins and where anywhere, you also need to use the correct delimiters and data types.
Try the following and note using table and column aliases makes for an easier-to-read query.
Additionally, consider not using select * and reference only the columns you actually require, if possible.
SELECT u.*, p.*, (
SELECT GROUP_CONCAT(i.pho_file_name)
FROM post_images i
WHERE i.pho_post_id = p.ID
) AS photo_file_array
FROM users u
JOIN posts p ON p.post_author = u.Id
AND p.post_date = '2020-12-04 07:51:21'
WHERE u.Id = 1
ORDER BY p.ID;
Here is a full working query. The errors (double ONclause, WHERE clause in the wrong position, wrong quotes) are corrected. Moreover, the ID is compared to an integer now and the post_date to a timestamp literal. I've used table aliases to get this more readable.
SELECT
u.*,
p.*,
(
SELECT GROUP_CONCAT(pi.pho_file_name)
FROM post_images pi
WHERE pi.pho_post_id = p.id
) AS photo_file_array
FROM users u
INNER JOIN posts p ON p.post_author = u.id
AND p.post_date = TIMESTAMP '2020-12-04 07:51:21'
WHERE u.id = 1
ORDER BY p.id;
As to the tables: I suggest you are more consistent with your column names. Why do you call the post ID post_author? One would assume a name here. Just call it post_id in every table. And you don't have to precede columns with abreviations like pho. Just qualify all columns with their tables like I did in my query.
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
I'm trying to do something like thisin MySQL. Query on one table with a list of ids from another table. The Group_Concat return a list of comma separated ids that i want to use in my first select. My try results in an error.
(Error Code: 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 'IN ( SELECT GROUP_CONCAT(t.id SEPARATOR ',') FROM m.my_aspnet_detai' at line 2)
How does one write this with correct syntax?
SELECT * FROM m.my_aspnet_membership m
where m.userId = IN
(
SELECT GROUP_CONCAT(t.id SEPARATOR ',')
FROM m.my_aspnet_details t
WHERE t.customerid = '2'
);
No need to GROUP_CONCAT
SELECT * FROM m.my_aspnet_membership m
where m.userId = IN
(
SELECT t.id
FROM m.my_aspnet_details t
WHERE t.customerid = '2'
);
Or even better to use JOIN
SELECT *
FROM m.my_aspnet_membership
INNER JOIN m.my_aspnet_details t ON t.id=m.userId
WHERE t.customerid = '2'
I have a query like this
UPDATE t_prd_cost_compare
SET
2015_AUG_PRD_UNIT_PRICE=i.PRD_UNIT_PRICE,
2015_AUG_PRD_SELLING_PRICE=i.PRD_SELLING_PRICE,
2015_AUG_PRD_IN_PATIENT_LIST_PRICE=i.PRD_IN_PATIENT_LIST_PRICE,
2015_AUG_PRD_OUT_PATIENT_LIST_PRICE=i.PRD_OUT_PATIENT_LIST_PRICE
FROM (
SELECT PRODUCTID,PRD_UNIT_PRICE,PRD_SELLING_PRICE,PRD_IN_PATIENT_LIST_PRICE,PRD_OUT_PATIENT_LIST_PRICE
FROM t_product_catalog
LEFT JOIN T_adjust ON IAJ_PRODUCTID=PRODUCTID AND IAJ_ADJNO IS NULL
WHERE PRODUCTID>1 AND (DATE(IAJ_DATE) = '2015-01-01')
GROUP BY IAJ_PRODUCTID
) AS i
WHERE i.PRODUCTID = t_prd_cost_compare.PRODUCTID
I get error like this
Error Code: 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 'FROM (
SELECT PRODUCTID,PRD_UNIT_PRICE,PRD_SELLING_PRICE,PRD_IN_PATIENT_LIST_PRI' at line 7
I done checked the select statement is correct, but I still get error!
Any idea?
Issue solved, here is the solution
Update
Competition as C
inner join (
select CompetitionId, count(*) as NumberOfTeams
from PicksPoints as p
where UserCompetitionID is not NULL
group by CompetitionID
) as A on C.CompetitionID = A.CompetitionID
set C.NumberOfTeams = A.NumberOfTeams

I have this query and appearently it's faulty?
I'm trying to join fices with mems so I can have the ficeID along with all the results from mems(These queries work individually). What am I doing wrong?
SELECT *
FROM mems
WHERE deleted <> -1
ORDER BY sort_mems
LEFT JOIN SELECT ficeID
FROM fices
Result:
#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 'LEFT JOIN SELECT ficeID FROM offices LIMIT 0, 30' at line 1
You have JOIN clause after ORDER BY. You should place it in FROM.
I suggest you define condition of a LEFT JOIN
Also, I suggest you surround you temp tables with brackets:
SELECT m.*, t1.officeID
FROM members m
LEFT JOIN offices t1
ON m.memberID = t1.memberID
WHERE m.deleted <> -1
ORDER BY m.sort_membername;
Yes, you have the LEFT JOIN in the wrong spot (it should go after your FROM clause, and you also seem to be missing a join criteria (the ON part, this tells the database how these tables are related):
SELECT *
FROM mems m
LEFT JOIN fices f
ON m.??? = f.???
WHERE deleted <> -1
ORDER BY sort_mems
