I have a table like below (refer table 1) , which can have multiple ids. I want to split the Reviewer id and get the first name and last name from table 2 and display in table 1 column 2 and 3 using sql.
Table 1
| Reviewer id/s| Name 1 |Name 2|
| -------------| -------|------|
| 123; 124 | row | row |
| 126; 156 | row | row |
Table 2
| Reviewer id | First Name |Last name |
| -------------| -----------|----------|
| 123 | Apple | A |
| 124 | Banana | B |
| 125 | Rose | Rose |
| 156 | Orange | I |
| 157 | Purple | J |
Try this
select value,first_name,last_name from Tabel1 cross apply string_split(Reviewer_id,';') inner join Table2 on Tabel2.Reviewer_id=value

I have two MySQL tables (table_a and table_b) and a join table (table_c).
Table Structures:
table_a:
__________________
| table_a: |
|----------------|
| id |
| result_column |
------------------
table_b:
__________________
| table_b: |
|----------------|
| id |
| name |
------------------
table_c:
__________________
| table_c: |
|----------------|
| id |
| table_a_id |
| table_b_id |
------------------
My Goal:
I want to find a query that will:
Iterate over every table_a record and get the table_a.id value
Find any records in table_c which have a matching table_c.table_a_id value
For each matching record in table_c get the table_c.table_b_id value
Find the record in table_b which has a matching table_b.id value
For that matching record in table_b get the table_b.name value
In table_a, concatenate each matched name value into the corresponding table_a.result_column
Example:
Before the Query:
_______________________ _________________________________ ________________
| table_a: | | table_c: | | table_b: |
|---------------------| |-------------------------------| |--------------|
| id | result_column | | id | table_a_id | table_b_id | | id | name |
|-----|---------------| |-----|------------|------------| |-----|--------|
| 1 | | | 1 | 1 | 3 | | 1 | Kevin |
| 2 | | | 2 | 1 | 4 | | 2 | Jesse |
| 3 | | | 3 | 2 | 2 | | 3 | Karen |
----------------------- | 4 | 3 | 1 | | 4 | Tim |
| 5 | 3 | 5 | | 5 | Lauren |
--------------------------------- ----------------
After the Query:
_______________________ _________________________________ ________________
| table_a: | | table_c: | | table_b: |
|---------------------| |-------------------------------| |--------------|
| id | result_column | | id | table_a_id | table_b_id | | id | name |
|-----|---------------| |-----|------------|------------| |-----|--------|
| 1 | Karen, Tim | | 1 | 1 | 3 | | 1 | Kevin |
| 2 | Jesse | | 2 | 1 | 4 | | 2 | Jesse |
| 3 | Kevin, Lauren | | 3 | 2 | 2 | | 3 | Karen |
----------------------- | 4 | 3 | 1 | | 4 | Tim |
| 5 | 3 | 5 | | 5 | Lauren |
--------------------------------- ----------------
For absolute clarity, I understand that this is incredibly bad practice within a relational data-table. This is as far from normalization as one can get. I would never design a database like this. I was tasked with creating a custom column with a list of values purely for a business case.
The query you seem to want is:
select c.table_a_id, group_concat(b.name separator ', ')
from c join
b
on c.table_b_id = b.id
group by c.table_a_id;
If you actually want to update a, you can put this into an update statement:
update a join
(select c.table_a_id, group_concat(b.name separator ', ') as names
from c join
b
on c.table_b_id = b.id
group by c.table_a_id
) cb
on cb.table_a_id = a.id
set result_column = cb.names
Previous answer is close; but you also required that you only want the records matched in table C that are in A.
The first query does not meet this requirement; but the update statement does, as it will only update records in table A, if the id matches the table_a_id value pulled from table C.
Given what you said you wished for the end result, the update statement above would work.
If you wish to be explicit in your logic, just add a join from table A to table C.
select a.id, group_concat(b.name separator ', ')
from a
join c ON (a.id = c.table_a_id)
join b ON (c.table_b_id = b.id)
group by a.id;
I have these three tables and I want to get the sum of the price field of table 3 linked to table 1, table 2 being linked to table 1 and 3:
Table 1 - Tecnic
+--------------+------------+
| id_tecnic | name |
+--------------+------------+
| 1 | Michael |
| 2 | Billy |
| 3 | Joe |
+--------------+------------+
Table 2 - Linked
+--------------+------------+------------+
| id_linked | id_tecnic | id_mer |
+--------------+------------+------------+
| 1 | 1 | 4 |
| 2 | 3 | 1 |
| 3 | 3 | 2 |
+--------------+------------+------------+
Table 3 - Mer
+--------------+------------+
| id_mer | price |
+--------------+------------+
| 1 | 30 |
| 2 | 70 |
| 3 | 50 |
| 4 | 10 |
+--------------+------------+
Result
+--------------+------------+-------------+
| id_tecnic | name | total_price |
+--------------+------------+-------------+
| 1 | Michael | 10 |
| 2 | Billy | 0 |
| 3 | Joe | 90 |
+--------------+------------+-------------+
I have tried this:
SELECT te.id_tecnic,
SUM(m.price)
FROM tecnic te
LEFT JOIN linked l ON te.id_tecnic = l.id_tecnic
LEFT JOIN mer m ON l.id_mer = m.id_mer
GROUP BY te.id_tecnic
Billy doesn't have record in Table 2 - Linked so with purpose to have Billy in result set you have to start from table Table 3 - Mer, like:
SELECT te.id_tecnic, te.name, SUM(m.price)
FROM mer m
LEFT jOIN linked l ON l.id_mer = m.id_mer
LEFT JOIN te ON te.id_tecnic = l.id_tecnic
GROUP BY te.id_tecnic;
I have two tables (as seen bellow) and i want to join them and select the person who has multiple values form the second table. The first table is a list of all people and their unique IDs, the second table is a list of peoples favorite colors.
Table A.: Unique ID | Name
+-----+-------------+
| uid | name |
+-----+-------------+
| 321 | Ana |
| 662 | Nick |
| 003 | Fred |
+-----+-------------+
Table B.: Table ID | Unique ID | Color ID
+----------+--------+-----------+
| id | uid | color_id |
+----------+--------+-----------+
| 1 | 121 | 1 |
| 2 | 127 | 2 |
| 3 | 003 | 11 |
| 4 | 002 | 11 |
| 5 | 111 | 3 |
| 6 | 044 | 5 |
| 7 | 003 | 5 |
| 8 | 003 | 8 |
+----------+--------+-----------+
So i want to select only the users (uid) who matches all the colors given, for example 11 and 8 (red and fusia). In this case that would be user 003 | Fred, and only have 1 row per match, and not multiple (for each value).
I have tried using where color_id IN (x,y,z...) but this will return any person who has at least 1 color in the list
You can try below -
select uniqueid, name from tableA a
inner join tableB b on a.uniqueid=b.uid
where color_id in (11,8)
group by uniqueid, name
having count(distinct color_id)=2
you can do your wish by
select distinct tableA.uid, tableA.name tableB.color_id from tableA
inner join tableB on tableA.uniqueid=tableB.uid
group by tableA.uid , tableA.name ,tableB.color_id
having count(distinct color_id)=2
For some reason I am having difficulty wording this question but I will try my best. I've been searching for 2 days on and off now and haven't found a good solution to the issue.
I have a Table called InventoryNode;
_________________________________________________
| InvID | ID | Slot | ItemID1 | ItemID2 | ItemID3 |
|-------|----|------|---------|---------|---------|
| 1 | 1 | Neck | 10 | 22 | 66 |
| 1 | 2 | Head | 26 | 23 | 56 |
| 1 | 3 | Leg | 19 | 21 | 76 |
And another table called Inventory which stores the Node ID in each column
_____________________________
| ID| Neck | Head | Leg | ... |
|---|------|------|-----|-----|
| 1 | 1 | 2 | 3 | 66 |
If there a way I can insert the node ID's into the Inventory table based off the InvID and populate all the columns with the correct name with the Node's ID?
Something like this?
INSERT INTO Inventory INNER JOIN InventoryNode ON
(Inventory.ID = InventoryNode.InvID) WHERE Inventory.column_name =
InventoryNode.Slot SET InventoryNode.InvID
I have a table that looks like this:
+----+--------+-------+
| id | entity | word |
+----+--------+-------+
| 1 | 1 | red |
| 2 | 1 | green |
| 3 | 1 | blue |
| 4 | 2 | car |
| 5 | 2 | truck |
| 6 | 2 | train |
| 7 | 3 | water |
| 8 | 3 | milk |
| 9 | 3 | soda |
+----+--------+-------+
If I do a search for blue I would like to get red, green and blue as an answer. Right now I am using 2 queries. One to find the 'entity' number and one to find all the words with the same 'entity' number.
Try this. Join is much faster than subquery
select distinct t2.word from Table t1
INNER JOIN Table t2 on t2.entity=t1.entity
where t1.word="blue";
SELECT *
FROM TABLE_NAME
WHERE entity IN
(SELECT entity
FROM TABLE_NAME
WHERE word='blue');
