I have two tables
rules
With three step hierarchy
|id | name | parent |
|---|-------|--------|
| 1 | A | 0 |
| 2 | B | 0 |
| 3 | A(1) | 1 |
| 4 | A(2) | 1 |
| 5 | B(1) | 2 |
| 6 | A(1.1)| 3 |
| 7 | A(1.2)| 3 |
| 8 | A(2.1)| 4 |
| 9 | B(1.1)| 5 |
| 10| A(3) | 1 |
Subject
|id | date | rules | group |
|---|---------------------|-------|-------|
| 1 | 2016-05-20 18:24:20 | 2 | AQR48 |
| 2 | 2016-05-20 19:31:17 | 5 | AQR52 |
| 3 | 2016-05-21 18:11:37 | 6,7,4 | AQR48 |
I need to get second step rules based on group and ruleid(first step) of subject table data
When group = 'AQR48' and rules.parent=1 result should be
|id | name | parent |
|---|-------|--------|
| 3 | A(1) | 1 |
| 4 | A(2) | 1 |
I tried it like this but with out success.
select rules.id,rules.name,rules.parent from rules left join subject on find_in_set(rules.id,subject.rules) where rules.parent=1 AND subject.group='AQR48'
With this I get output as
|id | name | parent |
|---|-------|--------|
| 4 | A(2) | 1 |
Anyone could help me with this

I have a table in MySQL that has data and I want to achieve some sort of pivoting from the table, which has become complicated for me. I have tried looking into this but nothing seems to work for me. This is the structure of my table :
roomid| day| 1 | 2 | 3 | 4 | 5 | 6 |
------+----+---+---+---+---+---+---+
1 | 1 |BIO| | | | | |
1 | 2 | |CHE| | | | |
1 | 3 | | | | | |ENG|
1 | 4 | | |KIS| | | |
1 | 5 | | | | | |PHY|
2 | 1 |BIO| | | | | |
2 | 2 | |CHE| | | | |
2 | 3 | | | | |ENG| |
2 | 4 | | |KIS| | | |
2 | 5 | | | | | |PHY|
This table is holding timetable data, the roomid is id for rooms and the day is days from monday to friday (1 to 5). The columns 1 to 6 are period ids.
I need to organize the data to achieve results that show period ids for each class, each day. something like this :
|roomid| 1 | 2 | 3 | 4 | 5 | 6 | 1 | 2 | 3 | 4 | 5 | 6 | 1 | 2 | 3 | 4 | 5 | 6 | 1 | 2 | 3 | 4 | 5 | 6 | 1 | 2 | 3 | 4 | 5 | 6 |
-------+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
1 |BIO| | | | | | |CHE| | | | | | | | | |ENG| | |KIS| | | | | | | | |PHY|
2 |BIO| | | | | | |CHE| | | | | | | | | |ENG| | |KIS| | | | | | | | |PHY|
Kindly notice that the period ids repeat themselves for different days.
You can use conditional aggreagtion:
select room_id,
max(case when day = 1 then slot_1 end) as day_1_slot_1,
max(case when day = 1 then slot_2 end) as day_1_slot_2,
. . .
max(case when day = 2 then slot_1 end) as day_2_slot_1,
max(case when day = 2 then slot_2 end) as day_2_slot_2,
. . .
from schedule s
group by room_id
While not claiming to be a definitive solution, a normalised design might be somewhat as follows. Frankly, it stretches credulity to suggest that the present design is somehow more appropriate than this.
+--------+-----+------+---------+
| roomid | day | slot | subject |
+--------+-----+------+---------+
| 1 | 1 | 1 | BIO |
| 2 | 1 | 2 | BIO |
| 1 | 2 | 2 | CHE |
| 2 | 2 | 2 | CHE |
| 1 | 4 | 3 | KIS |
| 2 | 4 | 3 | KIS |
| 2 | 3 | 5 | ENG |
| 1 | 3 | 6 | ENG |
| 1 | 5 | 6 | PHY |
| 2 | 5 | 6 | PHY |

wondering if anyone one can assist,
I have a fixed reference table
tblConfig_qC
----------------
| id | value |
----------------
| 1 | optionA |
| 2 | optionB |
| 3 | optionC |
| 4 | optionD |
| 5 | optionE |
| 6 | optionF |
| 7 | optionG |
----------------
And a tblSubmission table where I have 3 columns which stores which of the option users selected (from the tblConfig_qC table)
User can select between 1 to 3 options
So typically, rows can be like:
tblSubmissions
------------------------------------
| id | qC1 | qC2 | qC3 |
------------------------------------
| 1 | optionB | | |
| 2 | optionA | optionD | optionE |
| 3 | optionC | optionD | optionF |
| 4 | optionD | optionF | |
------------------------------------
What i need to do is create a summary of counts:
-------------------------
| id | Options | Counts |
-------------------------
| 1 | optionA | 0 |
| 2 | optionB | 1 |
| 3 | optionC | 1 |
| 4 | optionD | 3 |
| 5 | optionE | 1 |
| 6 | optionF | 2 |
| 7 | optionG | 0 |
-------------------------
I can do this for one column but how do i add the counts of the other 2?
SELECT q.value AS 'Option',
COUNT(s.qC1) AS 'qC1',
FROM tblConfig_qC q
LEFT JOIN tblSubmission s ON q.value = s.qC1
group by q.value ORDER BY q.value;
I have a question very similar to this one, but different (aka, I couldn't extend the answer to that one to fit my purposes. Due to the second WHERE condition, specifically).
I have a table which tracks the visit number for customers. There are two types of visits:
| ID | InStoreVisit | InStoreDate | OnlineVisit | OnlineDate |
|----|--------------|-------------|-------------|------------|
| 1 | 1 | 1/1/11 | | |
| 1 | 2 | 1/2/11 | | |
| 1 | | | 1 | 1/3/11 |
| 1 | 3 | 1/4/11 | | |
| 2 | | | 1 | 2/2/12 |
| 2 | 1 | 2/3/12 | | |
| 2 | | | 2 | 2/4/12 |
I need to create a new column which has a sort of 'global visit number' as such:
| ID | InStoreVisit | InStoreDate | OnlineVisit | OnlineDate | GobalVisit |
|----|--------------|-------------|-------------|------------|------------|
| 1 | 1 | 1/1/11 | | | 1 |
| 1 | 2 | 1/2/11 | | | 2 |
| 1 | | | 1 | 1/3/11 | 3 |
| 1 | 3 | 1/4/11 | | | 4 |
| 2 | | | 1 | 2/2/12 | 1 |
| 2 | 1 | 2/3/12 | | | 2 |
| 2 | | | 2 | 2/4/12 | 3 |
I'm getting mixed up on the WHERE condition with which I can do the self-join. Any advice greatly appreciated.
My first data table is couponsnmaster
+-----------+----------+------------+
|couponsnid | couponid | couponsn |
+-----------+----------+------------+
| 1 | 1 | 1000 |
| 2 | 1 | 1001 |
| 3 | 1 | 1002 |
| 4 | 1 | 1003 |
| 5 | 1 | 1004 |
| 6 | 1 | 1005 |
+-----------+----------+------------+
My second data table is distribute
+-----------+--------------+--------------+--------------+
| distid | couponid | couponsnid | status |
+-----------+--------------+--------------+--------------+
| 1 | 1 | 1 | distribute |
| 2 | 1 | 2 | distribute |
| 3 | 1 | 3 | distribute |
| 4 | 1 | 1 | returned |
+-----------+--------------+--------------+--------------+
I want to fetch all "couponsn" from "couponsnmaster" with respect to "couponid" except status is " distribute" or "sold" or "bonus" in table "distribute"....
Try this query:
SELECT c.couponsn FROM
couponsmaster c INNER JOIN distribute d
ON c.couponsid = d.couponsid
WHERE d.status NOT IN('distribute','sold','bonus')
This is my tables which I need get data from these tables. Each user can under many type of groups for example 2, 3, 4
1)groups
|gp_id|gp_name|gp_status|
-------------------------------------
| 1 | Admin | Active |
| 2 | R&D | Active |
| 3 | Sales | Active |
| 4 | IT | Active |
2)modules (FK of table parent_modules)
|mod_id| mod_name| pmod_id |
---------------------------------------------
| 1 | name1 | 1 |
| 2 | name2 | 1 |
| 3 | name3 | 2 |
| 4 | name4 | 3 |
| ... | name... | 3 |
mod_id = 5,6,7.. and so on
3)parent_modules
|pmod_id| mod_name |pmod_status|
-----------------------------------------
| 1 | Contact Us | Active |
| 2 | Account Settings | Active |
| 3 | System Settings | Active |
4)group_details
(FK of table groups) (FK of table modules)
|gpd_id | gp_id | mod_id | base_gpd_rule_view/edit/update/insert |
-----------------------------------------------------------------------
| 1 | 3 | 1 | on |
| 2 | 3 | 2 | on |
| 3 | 3 | 3 | |
| 4 | 3 | 4 |
| 5 | 3 | 5 | on |
| 6 | 3 | 6 |
| 7 | 3 | 7 |
| 8 | 4 | 6 |
| 9 | 4 | 7 | on |
| 10 | 4 | 8 | on |
I have to select once only of duplicate results from group_details and this is the result that I want.
| gp_id | mod_id |
----------------------------------------------
| 3 | 1 |
| 3 | 2 |
| 3 | 3 |
| 3 | 4 |
| 3 | 5 |
| 3 | 6 |
| 3 | 7 |
| 4 | 8 |
So far this is what I did in my query but it shows me duplicate record.
//get user groups store in database. example group in database:2, 3, 4
$GroupList = explode(", ", $UserDetail['u_group']);
foreach($GroupList as $a)
{
$getParentModuleSQL = base_executeSQL("SELECT * FROM parent_modules WHERE pmod_status<>'Disable'" );
$count1 = base_num_rows($getParentModuleSQL);
while($ParentModuledata_row = base_fetch_array($getParentModuleSQL))
if ($count1!= 0)
{
base_executeSQL("SELECT gp.gp_id AS ID FROM group_details AS gp, modules AS m WHERE m.pmod_id =". $ParentModuledata_row['pmod_id'] ." AND gp.gp_id=". $a ." AND gp.mod_id = m.mod_id" AND (base_gpd_rule_view='on' OR base_gpd_rule_add='on' OR base_gpd_rule_edit='on' OR base_gpd_rule_delete='on') GROUP BY gp.mod_id);
}
}
i still dont understand your problems. if you want all modules a gp_id has access to - select * from group_details where gp_id = XX. If you just want each module, select * from modules.
