I am getting this error
Unknown column 'op.name' in 'field list'
Is there any possibility to use op.name outside the scope?
JOIN the subquery in the WHERE clause instead of using the IN predicate. This way you can select the name from it.
But you didn't select the column name from in the subquery. You selected only the profile_id, you have to select it with the profile_id. Something like:
SELECT
IFNULL(oea.`name`, op.name) AS Consultation
FROM `a` ca
JOIN `b` oea ON ca.`consultation_id` = oea.id AND oea.status = 1
INNER JOIN
(
SELECT profile_id, name
FROM d pp
WHERE pp.status='1'
UNION
SELECT op.id, name
FROM e op
WHERE op.status
) AS op ON oea.employee_profile_id = op.profile_id
LEFT OUTER JOIN c oeal ON oea.`location_id` = oeal.id
WHERE ca.status = 1;
I assumed that the two tables have the name column, if one of them didn't have it, you have to use null instead.

I have bd hf3 and 5 tables there:
active_preset with columns (id , preset_id)
preset with columns (id , birja_id, trend_id, fractal, interval_up)
birja with columns (id , name)
trend with columns (id , name)
uq_active_preset with columns (id , birja, trend, fractal, interval_up)
In table preset I have a few records. Some of them are in table active_preset by foreign key preset_id. In table active_preset a few records exist once , a few more than once.
I need to update table uq_active_preset with records from table active_preset disregarding repetitions of records if they are present.
I did query from active_preset and it works good:
SELECT
b.name AS birja, p.fractal AS fractal , tre.name AS trend, p.interval_up AS interval_up
FROM hf3.active_preset AS ap
INNER JOIN hf3.preset AS p on p.id = ap.preset_id
INNER JOIN hf3.birja AS b on b.id = p.birja_id
INNER JOIN hf3.trend AS tre on tre.id = p.trend_id
GROUP BY b.name, p.fractal, tre.name, p.interval_up
HAVING COUNT(*) >= 1
But I don't know how to update uq_active_preset
I tried this and it returns syntax error:1064 :
UPDATE hf3.uq_active_preset uap SET
uap.birja = st.birja ,
uap.fractal = st.fractal,
uap.trend = st.trend,
uap.interval_up = st.interval_up,
FROM (SELECT b.name AS birja, p.fractal AS fractal , tre.name AS trend, p.interval_up AS interval_up
from hf3.active_preset AS ap
INNER JOIN hf3.preset AS p on p.id = ap.preset_id
INNER JOIN hf3.birja AS b on b.id = p.birja_id
INNER JOIN hf3.trend AS tre on tre.id = p.trend_id
GROUP BY b.name, p.fractal, tre.name, p.interval_up
HAVING COUNT(*) >= 1
) st
when you make an update using from is like you join the updated table with your query result. So, you need also a where statement in order to tell where those two are connected. Also, don't use alias of your updated table on set statement.
You need something like that:
UPDATE hf3.uq_active_preset uap SET birja=st.birja,fractal=st.fractal,trend=st.trend,interval_up=st.interval_up
FROM (SELECT b.name AS birja, p.fractal AS fractal , tre.name AS trend, p.interval_up AS interval_up
from hf3.active_preset AS ap
INNER JOIN hf3.preset AS p on p.id = ap.preset_id
INNER JOIN hf3.birja AS b on b.id = p.birja_id
INNER JOIN hf3.trend AS tre on tre.id = p.trend_id
GROUP BY b.name, p.fractal, tre.name, p.interval_up
HAVING COUNT(*) >= 1
) st
where uap.fkey=st.fkey
I have following query:
SELECT
a.id_posicion,
a.profesional,
MAX( a.fecha_hora ) AS fechaPosicion,
a.latitud,
a.longitud,
b.tipo_profesional,
b.nombre,
b.apellidos,

FROM tb_ultima_posicion_pro a
INNER JOIN users b ON b.id = a.profesional
INNER JOIN tb_profesionales c ON c.id_profesionales = b.tipo_profesional
INNER JOIN tb_especialidades_profesional d ON d.profesional = b.id
INNER JOIN tb_especialidades e ON d.especialidad = e.id_especialidad
GROUP BY a.profesional
ORDER BY fechaPosicion DESC
What I need is to get all records from the table tb_ultima_posicion_pro, grouped by the field profesional, which means that I get only a row for each profesional (that is ok), and for each profesional I need to get te row with the newest field fecha_hora, which is a datetime field.
What I am getting with this query is a row for each profesional (ok) but not the one with the newest fecha_hora field value.
Alternatively, You can first fetch the maximum fetch_hora by grouping the table tb_ultima_posicion_pro and then can join other tables -
SELECT a.id_posicion
,a.profesional
,am.fecha_hora AS fechaPosicion
,a.latitud
,a.longitud
,b.tipo_profesional
,b.nombre
,b.apellidos
,c.tipo_profesional as tipoProfesional
,b.profile_image
,b.tel as tel
,e.especialidad as especialidad_profesional
,b.ciudad as ciudad
,b.departamento as departamento
,b.id_firebase as id_firebase
FROM tb_ultima_posicion_pro a
INNER JOIN (SELECT profesional
,MAX(fecha_hora) AS fecha_hora
FROM tb_ultima_posicion_pro
GROUP BY profesional) am ON a.profesional = am.profesional
AND a.fecha_hora = am.fecha_hora
INNER JOIN users b ON b.id = a.profesional
INNER JOIN tb_profesionales c ON c.id_profesionales = b.tipo_profesional
INNER JOIN tb_especialidades_profesional d ON d.profesional = b.id
INNER JOIN tb_especialidades e ON d.especialidad = e.id_especialidad

I have following sql statement:
INSERT INTO wk1_tbl (shohin_code, shohin_mei, variation_flag)
SELECT ha.HINCD, ha.HINNMA, if (g.goods_para_id IS NULL, 0, 1) AS variation
FROM ( SELECT KOSHINCD, count(HINCD) AS quatity
FROM sc.HINMTF
GROUP BY KOSHINCD ) AS group_set
INNER JOIN sc.HINMTA ha
ON ha.HINCD = group_set.KOSHINCD
INNER JOIN master_hankoya.goods g
ON ha.WEBHINID = g.goods_id
WHERE ha.HINKB = '2' and ha.DATKB <> '9';
I using INNER JOIN on multi-database ,so that you can see sc and master_hankoya is difference databases
When I run it ,I get error :
Unknown column 'g.goods_id ' in 'on clause'
You can see g alias for table master_hankoya.goods,and goods_id is a column in this
I guess that I have problem with INNER JOIN
Please help me correct it
Update : I check again and take a silly problem ,have a special character in query make it failed to run
try this
INSERT INTO wk1_tbl (shohin_code, shohin_mei, variation_flag)
SELECT ha.HINCD, ha.HINNMA, if (g.goods_para_id IS NULL, 0, 1) AS variation
FROM ( SELECT KOSHINCD, count(HINCD) AS quatity
FROM sc.HINMTF
GROUP BY KOSHINCD ) AS group_set
INNER JOIN sc.HINMTA ha
ON ha.HINCD = group_set.KOSHINCD
INNER JOIN
(select * from master_hankoya.goods ) g
ON ha.WEBHINID = g.goods_id
WHERE ha.HINKB = '2' and ha.DATKB <> '9';
Don't use alias name for master_hankoya.goods like
INSERT INTO wk1_tbl (shohin_code, shohin_mei, variation_flag)
SELECT ha.HINCD, ha.HINNMA, if (master_hankoya.goods.goods_para_id IS NULL, 0, 1) AS variation
FROM ( SELECT KOSHINCD, count(HINCD) AS quatity
FROM sc.HINMTF
GROUP BY KOSHINCD ) AS group_set
INNER JOIN sc.HINMTA ha
ON ha.HINCD = group_set.KOSHINCD
INNER JOIN master_hankoya.goods
ON ha.WEBHINID = master_hankoya.goods.goods_id
WHERE ha.HINKB = '2' and ha.DATKB <> '9';
INNER JOIN sc.HINMTA ha
Change this line to:
INNER JOIN HINMTA AS ha
INNER JOIN master_hankoya.goods g
Change that line to
INNER JOIN goods AS g
The syntax for setting an alias for a table is:
table_name AS table_alias
Can anyone tell me what is wrong with this query?
it gives a syntax error near the 2nd select
SELECT b.mc_boxes_idmc_boxes,
t.idtitles,
t.title,
t.languages_idlanguages,
MAX(h.idtitle_history),
MAX(h.edition)
(SELECT h.preview, h.file WHERE h.idtitle_history = MAX(h.idtitle_history))
FROM mc_boxes_has_titles b
LEFT JOIN titles t ON b.titles_idtitles = t.idtitles
LEFT JOIN title_history h ON h.titles_idtitles = t.idtitles
WHERE b.mc_boxes_idmc_boxes = 12
AND h.edition IS NOT NULL
GROUP BY b.mc_boxes_idmc_boxes, idtitles
ORDER BY b.sortorder;
looks like you are missing a comma after MAX(h.edition)
SELECT b.mc_boxes_idmc_boxes,
t.idtitles,
t.title,
t.languages_idlanguages,
MAX(h.idtitle_history),
MAX(h.edition),
(SELECT h.preview, h.file WHERE h.idtitle_history = MAX(h.idtitle_history))
FROM mc_boxes_has_titles b
LEFT JOIN titles t ON b.titles_idtitles = t.idtitles
LEFT JOIN title_history h ON h.titles_idtitles = t.idtitles
WHERE b.mc_boxes_idmc_boxes = 12
AND h.edition IS NOT NULL
GROUP BY b.mc_boxes_idmc_boxes, idtitles
ORDER BY b.sortorder;
besides the comma, you are selecting two fields in your subquery
SELECT b.mc_boxes_idmc_boxes,
t.idtitles,
t.title,
t.languages_idlanguages,
MAX(h.idtitle_history),
MAX(h.edition),
(SELECT preview FROM title_history WHERE idtitle_history = MAX(h.idtitle_history)),
(SELECT [file] FROM title_history WHERE idtitle_history = MAX(h.idtitle_history))
FROM mc_boxes_has_titles b
LEFT JOIN titles t ON b.titles_idtitles = t.idtitles
LEFT JOIN title_history h ON h.titles_idtitles = t.idtitles
WHERE b.mc_boxes_idmc_boxes = 12
AND h.edition IS NOT NULL
GROUP BY b.mc_boxes_idmc_boxes, idtitles
ORDER BY b.sortorder;
Adding to bluefeet's answer, you may want to check for reserved words. "File" for example is a reserved word in sql server.
Alias it as a virtual table. Change something like
SELECT b.mc_boxes_idmc_boxes,
t.idtitles,
t.title,
t.languages_idlanguages,
MAX(h.idtitle_history),
MAX(h.edition)
(SELECT h.preview, h.file WHERE h.idtitle_history = MAX(h.idtitle_history))
FROM mc_boxes_has_titles b
LEFT JOIN titles t ON b.titles_idtitles = t.idtitles
LEFT JOIN title_history h ON h.titles_idtitles = t.idtitles
WHERE b.mc_boxes_idmc_boxes = 12
AND h.edition IS NOT NULL
GROUP BY b.mc_boxes_idmc_boxes, idtitles
ORDER BY b.sortorder) as virtual_column_alias;
Check this out. Hope this will work.
This is my current query:
$sel = "SELECT
db1t1.userid, db1t1.customer_id, db2t1.customers_id, db2t1.orders_id, db2t2.products_price
FROM
database1.table1 db1t1
LEFT JOIN database2.table1 db2t1 ON
db1t1.customer_id = db2t1.customers_id
LEFT JOIN database2.table2 db2t2 ON
db2t1.orders_id = db2t2.orders_id
WHERE db1t1.userid IN(
SELECT
l.userid, l.username, r.username, r.cus_id
FROM
database1.table3 l
LEFT JOIN database2.table4 r ON
l.username = r.username
WHERE r.cus_id = '1234'
)";
Error message:
Operand should contain 1 column(s)
The error occurred because that you returned a result with multiple columns to an IN clause.
Try this:
SELECT
`db1t1`.`userid`, `db1t1`.`customer_id`, `db2t1`.`customers_id`,
`db2t1`.`orders_id`, `db2t2`.`products_price`
FROM `database1`.`table1` AS `db1t1`
LEFT JOIN `database2`.`table1` AS `db2t1`
USING (`customers_id`)
LEFT JOIN `database2`.`table2` AS `db2t2`
USING (`orders_id`)
WHERE `db1t1`.`userid` IN (
SELECT `l`.`userid`
FROM `database1`.`table3` AS `l`
LEFT JOIN `database2`.`table4` AS `r`
USING (`username`)
WHERE `r`.`cus_id` = 1234
)
What are you trying to achieve ? Maybe we can find a better solution.
Also, I think that you should do an INNER JOIN instead of a LEFT JOIN in the subquery.
