I have 2 tables with this configuration:
table language('id', 'language_name', 'iso_code')
table translation('id', 'language_id', 'translated_text')
In the first table I have records:
---------------------------------
| id | language_name | iso_code |
---------------------------------
| 1 | English | en |
| 2 | Espanõl | es |
| 3 | Français | fr |
---------------------------------
The second table:
--------------------------------------
| id | language_id | translated_text |
--------------------------------------
| 1 | 1 | Good Morning |
| 2 | 1 | How are you? |
| 1 | 2 | Buenos dias |
| 2 | 3 | Comment ça va? |
--------------------------------------
All English text strings exist, but some of the other languages dont.
I would like to show a table with ALL English text strings and corresponding translations, like:
----------------------------------------
| text_id | en | es |
----------------------------------------
| 1 | Good Morning | Buenos dias |
| 2 | How are you? | |
----------------------------------------
or
-------------------------------------------
| text_id | en | fr |
-------------------------------------------
| 1 | Good Morning | Comment ça va? |
| 2 | How are you? | |
-------------------------------------------
Any ideas?
Just keep doing left joins to same table on the ID, but extra columns representing their language...
Edited to show English if no value in corresponding columns per comment inquiry.
select
eng.id,
eng.translated_text InEnglish,
coalesce( spn.translated_text, eng.translated_text ) InSpanish,
coalesce( frn.translated_text, eng.translated_text ) InFrench
from
translation eng
left join translation spn
on eng.id = spn.id
and spn.Language_ID = 2
left join translation frn
on eng.id = frn.id
and spn.Language_ID = 3
where
eng.Language_id = 1
order by
eng.id

what is the right MYsql statement to generation the result I want?
pls anyone help, I keep looking for the answer found nowhere. I am not good in any database.
thank you so much
I'm assuming your 2nd table name is tdate, and data on trans_code and date_added that's being selected is the latest value if there are more than one data from the same tperson_id on table tdate
SELECT tp.tperson_id, tp.first_name, MAX(td.trans_code), MAX(td.date_added)
FROM tperson tp
LEFT JOIN tdate td
ON tp.tperson_id = td.tperson_id
GROUP BY tp.tperson_id
Update: I want to use dynamic sql to select question as column and put answer in row, like cursor or loop, is that possible?
I want the select result like this
+--------+---------------+--------------------------------------------------------------------------+
| userid | Living Status | This is another question get from row and it's longer than 64 characters |
+--------+---------------+--------------------------------------------------------------------------+
| 19 | married | q2_opt3 |
+--------+---------------+--------------------------------------------------------------------------+
And here is my query
select
userid,
min(if(question.ordering=1,o.name,NULL )) as 'Living Status',
min(if(question.ordering=2,o.name,NULL )) as 'This is another question get from row and it's longer than 64 characters'
from answer
inner join question on question.key_value = answer.key_value
inner join q_option o on question.id = o.question_id and o.value = answer.answer
where userid in (19)
GROUP BY id
The question table is like
+----+----------+---------------------------------------------------------------------------+--------------+
| id | ordering | question | key_value |
+----+----------+---------------------------------------------------------------------------+--------------+
| 1 | 1 | Living Status | livingStatus |
| 2 | 2 | This is another question get from row and it's longer than 64 characters | question_2 |
+----+----------+---------------------------------------------------------------------------+--------------+
The answer table is like
+----+--------+--------------+--------+
| id | answer | key_value | userid |
+----+--------+--------------+--------+
| 1 | 2 | livingStatus | 19 |
| 2 | 3 | question_2 | 19 |
+----+--------+--------------+--------+
The q_option table is like
+----+----------+-------------+-------+
| id | name | question_id | value |
+----+----------+-------------+-------+
| 1 | single | 1 | 1 |
| 2 | married | 1 | 2 |
| 3 | divorced | 1 | 3 |
| 4 | q2_opt1 | 2 | 1 |
| 5 | q2_opt2 | 2 | 2 |
| 6 | q2_opt3 | 2 | 3 |

I have two tables
Master table
|-----------|--------|------------|
| id_client | name | ci |
|-----------|--------|------------|
| 1 | B | 123 |
| 2 | A | 234 |
| 3 | C | 345 |
|-----------|--------|------------|
Detail of equipments
|-----------|--------------|
| id_client | id_equipment |
|-----------|--------------|
| 1 | 1 |
| 1 | 2 |
| 2 | 3 |
|-----------|--------------|
The result that I expected is:
All clientes with or without equipments
|-----------|----------------|----------------|
| id_client | id_equipment | numberEquipment|
|-----------|----------------|----------------|
| 1 | 1 | Equip1 |
| 1 | 2 | Equip2 |
| 2 | 3 | Equip1 |
| 2 | - | Equip2 |
| 3 | - | Equip1 |
| 3 | - | Equip2 |
|-----------|----------------|----------------|
Client 1 have two equipments and this is the max cant of equipments assigned, then, all clientes with minor than two have to fill the detail empty two times. client 2 have one equipment assigned, the second will be empty, and cliente 3 doesnt have any equipment, then the two equipments will be empty.
I was implemented crosstab on jasperreport, i have to define de columnGroup, when the name of group Equipment1, equipment2... etc, doesnt exist on any row this column group doesnt show.
I hope someone can helpme.
Thanks.
SELECT CONCAT('EQUIPMENT ',g.ennum) AS numberEquipment,
g.ID_CLIENTE as id_client, g.ID_EQUIPO as id_equipment,
(SELECT #running1:= 0) AS running1,(SELECT #previous1:= 0) AS previous1
FROM (
SELECT c.ID_CLIENTE, eq.ID_EQUIPO
#running1:=if(#previous1=concat(eq.ID_CLIENTE),#running1,0) + 1 as ennum, #previous1:=concat(eq.ID_CLIENTE)
FROM CLIENTE AS c
LEFT JOIN detail_equipments AS eq ON eq.ID_CLIENTE = c.ID_CLIENTE
ORDER BY c.ID_CLIENTE ) AS g
GROUP BY g.ID_CLIENTE, g.ID_EQUIPO
ORDER BY ID_CLIENTE, g.ennum
this show
|-----------|----------------|----------------|
| id_client | id_equipment | numberEquipment|
|-----------|----------------|----------------|
| 1 | 1 | Equip1 |
| 1 | 2 | Equip2 |
| 2 | 3 | Equip1 |
| 3 | - | Equip1 |

Please be assured that I searched a lot on SE for an answer similar to mine but didn't get any good result and here I am asking for some help.
I have 3 tables as follows:
Table Professors:
+---------+--------+
| idProf | name |
+---------+--------+
| 1 | Ben |
| 2 | John |
| 3 | Bob |
+---------+--------+
Table Classes:
+---------+--------+------------+
| idClass | name | profRefId |
+---------+--------+------------+
| 1 | French | 1 |
| 2 | English| 1 |
| 3 | German | 3 |
| 4 | Science| 2 |
+---------+--------+------------+
Table Lessons:
+----------+----------+--------------+
| idLesson | name | classRefId |
+----------+----------+--------------+
| 1 | Lesson1 | 1 |
| 2 | Lesson2 | 1 |
| 3 | Lesson3 | 2 |
| 4 | Lesson4 | 4 |
| 5 | Lesson5 | 4 |
| 6 | Lesson6 | 3 |
+----------+----------+--------------+
Now, what I was struggling to achieve is:
I pass idProf as a URL parameter ($_GET['idProf'])
And I would like the right SQL statement based on that param to list all the classes for that professor and inside each class list its lessons.
Something that will look like this on a webpage:
Something like this?
SELECT a.name ProfessorName, b.name ClassName, c.name LessonName
FROM Professors a
INNER JOIN Classes b
ON a.idProf=b.profRefID
INNER JOIN Lessons c
ON b.idClass=c.classRefID
I'm relatively new to MySQL and have come across a problem to which I cannot seem to find a solution. I have searched but could not find an answer. I'm open to the possibility that I'm not asking the question correctly. Here goes:
I'm trying to use the name of a given column and the values within that column from one table to pull values from another table. The first table contains 3 columns with the response codified. The second table contains the definitions for each code for each item. The same number code is associated with different meanings depending on the item. For example:
table1 (this table cannot change):
--------------------------------------------------------------
|result_id | f_initial | l_name | item_A | item_B | item_C |
--------------------------------------------------------------
| 1 | j | doe | 1 | 3 | 2 |
| 2 | k | smith | 3 | 1 | 2 |
| 3 | l | williams | 2 | 2 | 1 |
--------------------------------------------------------------
table2 (this table can be modified, split, or whatever needs to be done):
-------------------------------------------
|item_id | item_name | score | definition |
-------------------------------------------
| 1 | item_A | 1 | agree |
| 2 | item_A | 2 | neutral |
| 3 | item_A | 3 | disagree |
| 4 | item_B | 1 | likely |
| 5 | item_B | 2 | not likely |
| 6 | item_B | 3 | no reply |
| 7 | item_C | 1 | yes |
| 8 | item_C | 2 | no |
-------------------------------------------
My goal is for the query to output the following:
--------------------------------------------------------------------
|result_id | f_initial | l_name | item_A | item_B | item_C |
--------------------------------------------------------------------
| 1 | j | doe | agree | no reply | no |
| 2 | k | smith | disagree | likely | no |
| 3 | l | williams | neutral | not likely | yes |
--------------------------------------------------------------------
Any assistance or guidance is greatly appreciated. Thank you in advance.
You must join the two tables on the item_A/B/C and score columns
select t1.result_id, t1.f_initial, t1.l_name,
t2a.definition as item_a,
t2b.definition as item_b,
t2c.definition as item_c
from table1 t1
join table2 t2a on t2a.score = t1.item_a
join table2 t2b on t2b.score = t1.item_b
join table2 t2c on t2c.score = t1.item_c
where t2a.item_name = 'item_A'
and t2b.item_name = 'item_B'
and t2c.item_name = 'item_C'
