SQL: Joining 3 tables to generate report dashboard - mysql

I am trying to join 3 different tables that holds my test execution results as "PASS", "FAIL" and "SKIP". There are 2 common properties in these 3 tables on the basis of which I need to club my result i.e. "BUILD_NUMBER" and "COMPONENT".
Tried several approach but does not get the desired result.
Best result reached so far.
Sample query:
select test_execution.COMPONENT, test_execution.BUILD_NUMBER,
count(test_execution.TEST_STATUS) as PASS from (test_execution
INNER JOIN test_execution_fail ON
test_execution.BUILD_NUMBER = test_execution_fail.BUILD_NUMBER) group by
COMPONENT,BUILD_NUMBER;
My tables look like below:
CREATE TABLE test_execution_skip (
BUILD_NUMBER int,
TEST_NAME varchar(255),
TEST_CLASS varchar(255),
COMPONENT varchar(255),
TEST_STATUS varchar(255)
);
Other two tables are exactly same with test_execution and test_execution_fail as their names.
test_execution table holds 3 records(all pass values), test_execution_fail table holds 2 records (all fail values) and test_execution_skip table holds 1 record(skip value).
I want to populate data that will show me BUILD_NUMBER, COMPONENT, TOTAL, PASS, FAIL, SKIP as records where TOTAL, PASS, FAIL and SKIP will show the respectives counts.
Any help is appreciated here.

Not sure if this answers your question but you could try something like this
WITH cte AS (
SELECT * FROM test_execution
union
SELECT * FROM test_execution_fail
UNION
SELECT * FROM test_execution_skip
)
SELECT t.*, (SKIP + FAIL + PASS) AS TOTAL FROM (
select
COMPONENT,
BUILD_NUMBER,
SUM(IF(TEST_STATUS = 'skip', 1, 0 )) as SKIP,
SUM(IF(TEST_STATUS = 'fail', 1, 0 )) as FAIL,
SUM(IF(TEST_STATUS = 'pass', 1, 0 )) as PASS
FROM cte
group by COMPONENT,BUILD_NUMBER
)t

Mysql query insert into only if select count > n

I have 2 queries:
SELECT COUNT(*) FROM a WHERE id = 1
//if row == 1
INSERT INTO a VALUES(fielda) VALUES('value')
Is there a way to merge these two queries into one? I tried with 'IF (count> 0, ..)' and similar, but the query is incorrect.
This involves inserting a new record into the table, taking care not to exceed a pre-set number of records for each field.
In theory it should be similar to an INSERT IF ...
Edit:
#Barmar I tried but I think I did not understand what you wrote (in fact I made a mistake in the query), I try to answer like this:
THE QUERY AFTER YOUR RESPONSE:
INSERT INTO table1 SELECT MAX(id) FROM table1 WHERE field1 = (SELECT id from a WHERE f = field2) HAVING COUNT(*) = 1 (all fields request) VALUES (all values request)
//field1 = id from table2
//field2 = id from another table: associative value
//ORIGINAL QUERY
//FIRST COUNT:
SELECT COUNT(*) from table1 WHERE field1 = (SELECT id FROM table2 WHERE f = field2)
//AFTER THE INSERT:
INSERT INTO table1 (all fields request) VALUES (all values request)
I came to mind this example I try to show you:
TABLE PLAYER: fields(ID, TEAMID, NAME) => (id=int, teamid=int associate to table team, name=varchar)
TABLE TEAM: fields(ID NAME) => (id=int, name=varchar)
Suppose that the players in a team are maximum 20, so you expect maximum 20 records associated by the player table for the same teamid value, or at least this is what we humans think, because for the computer can also be infinite. I was looking for a way to allow the insertion only in the case in which it is actually permissible to insert records, in this case the condition is that in the players table there are less than 21 records per team.
You can use INSERT ... SELECT, and put the condition in the SELECT query.
INSERT INTO player (teamid, name)
SELECT #teamid, #playername
FROM DUAL
WHERE (SELECT COUNT(*) FROM player
WHERE teamid = #teamid) < 20
DUAL is a dummy table when you need to select literal data, but need to include other clauses in the query.

Why am i getting "Subquery returns more than 1 row"

Hi I am making a webrowser game and I am trying to get monsters into my data base when I get the error:
Subquery returns more then 1 row
here is my code
INSERT INTO monster_stats(monster_id,stat_id,value)
VALUES
( (SELECT id FROM monsters WHERE name = 'Necroborg!'),
(SELECT id FROM stats WHERE short_name = 'atk'),
2);
any ideas how to fix this problem?
Try use LIMIT 1
INSERT INTO monster_stats(monster_id,stat_id,value) VALUES ((SELECT id FROM monsters WHERE name = 'Necroborg!' LIMIT 1),(SELECT id FROM stats WHERE short_name = 'atk' LIMIT 1),2);
Or you could use Insert from select, with join, if you have relations with 2 tables.
INSERT INTO monster_stats(monster_id,stat_id,value)
(SELECT monsters.id, stats.id, 2 as value FROM monsters
LEFT JOIN stats on monsters.id = stats.monsters_id
WHERE monsters.name = 'Necroborg!'
AND stats.short_name = 'atk'
)
MYSQL insert from select:
http://dev.mysql.com/doc/refman/5.1/en/insert-select.html
The problem is one or both of the following:
There is more than one monster named 'Necroborg!'.
There is more than on stat named 'atk'.
You need to decide what you want to do. One option (mentioned elsewhere) is to use limit 1 to get only one value from each statement.
A second option is to better specify the where clause so you get only one row from each table.
Another is to insert all combinations. You would do this with insert . . . select and a cross join:
INSERT INTO monster_stats(monster_id, stat_id, value)
SELECT m.id, s.id, 2
FROM (SELECT id FROM monsters WHERE name = 'Necroborg!') m CROSS JOIN
(SELECT id FROM stats WHERE short_name = 'atk');
A third possibility is that there is a field connecting the two tables, such as monster_id. But, based on the names of the tables, I don't think that is true.

How to loop through each row in MySQL table and get rows if conditions match

For my application I would like to do the following:
SELECT *
FROM `LLS_USERS`
LIMIT 0,111
WHERE
(`USR_LOGIN`=
(CONCAT(
(SELECT LEFT(`USR_FIRST_NAME`, 1) FROM `LLS_USERS`;),
(SELECT `USR_LAST_NAME`FROM `LLS_USERS`;)
);
)
)
Basically I need to select all the rows in the user table where the user's login matches up with the first initial of the user name concatinated with the user's last name. So the SQL query will generate a table for me of all the selected rows where this is true in phpMyAdmin.
I know I have 111 users in my database currently.
Does anyone know what's wrong with my syntax?
UPDATE: SOLUTION is:
SELECT *
FROM `LLS_USERS`
WHERE (
`USR_LOGIN` = ( left( `USR_FIRST_NAME` , 1 ) || `USR_LAST_NAME` )
)
LIMIT 0 , 111;
Take SQL as a (real life) Language here in this basic example:
Give me all rows of a table that match the condition loginname= 1 char of first name following lastname
->
SELECT * FROM LLS_USERS where USR_LOGIN= LEFT(USR_FIRST_NAME, 1)||USR_LAST_NAME
Thats all, thats the beautiness of SQL

MySQL: Insert using results of Select field from pair clause

I've got a requirement to add an additional item of data to an existing row and insert the result in a second table. The data item is different for each row I am selecting, so I can't just add it to the SELECT statement. The original query is:
SELECT player_id,token_id,email FROM players
WHERE token_id in (101,102) OR email in ("test4#test.com");
I'd like to be able to do something like a Row Constructor and write the query something like this:
SELECT player_id,token_id, email, key_val FROM players
WHERE (token_id, key_val) in ( (101, 'xyz'),(102,'abc'))
OR (email, key_val) in ( ("test4#test.com", 'qpr') );
So that the second value ('key_val') from the pair in the IN clause would be added into the SELECT output as the last column. And then the whole lot will get inserted into the final table.
The number of items in the IN clause will vary from 3 to potentially 100's.
Really sorry if this is a dup. I've looked up things like:
Select Query by Pair of fields using an in clause
MySQL: How to bulk SELECT rows with multiple pairs in WHERE clause
I guess I could use a temporary table but I'm concerned about the number of times that this is going to be called.
Edit--
To clarify, the source table is something like:
player_id, token_id, email
===================================
1 101 null
2 102 null
3 null test4#test.com
and the date being supplied is:
(token_id=101, key_val='xyz'),(token_id=102, key_val='abc'),(email='test4#test.com', key_val='qpr')
and the intended output would be:
player_id token_id email keyy_val
========== ========= ============== ========
1 101 null zyz
2 102 null abc
3 null test4#test.com qpr
Hope this makes it clearer.
try this
SELECT player_id,token_id, email, key_val
FROM players
WHERE token_id in (101,102) AND key_val IN ('xyz','abc')
OR ( email in ("test4#test.com") AND key_val IN ('qpr') );
EDIT -.
try this
SELECT player_id,token_id, email, key_val
FROM ( select player_id,token_id, email,
if(`token_id` =101 , 'xyz',
if(`token_id` =102 , 'abc' ,
if(email = "test4#test.com" , 'qpr' , NULL))
) key_val
from players
)p

Getting multiple values from a query

I write a query to get values from 3 tables but this is returning multiple values so can any one tell where i went wrong
select c.CompanyName,cd.FedTaxID,cd.EmailAddress,cd.PhoneNumber
from tblcustomerdetail cd,tblcustomer c
where c.FedTaxID in (
select FedTaxID
from tblcustomer
where CustomerID in (
select LOginID
from tbluserlogindetail
where UserName like "pa%" and RoleTypeID='20'
)
)
and cd.FedTaxID in (
select FedTaxID
from tblcustomer
where CustomerID in (
select LOginID
from tbluserlogindetail
where UserName like "pa%" and RoleTypeID='20'
)
);
My relation is here
My 3 tables are `tbluserlogindetails, tblcustomerdetails and tblCustomer'
1) Initially i will get `Login ID` from `tblUserLoginDetail ` based on the `user name`.
2) Next based on `LoginID` i will get `FedTaxID` from tblcustomerDetail`
3) Next based on 'FedTaxID' i will get the the required details from `tblcustomer'
SELECT
tblcustomer.CompanyName,
tblcustomerdetail.FedTaxID,
tblcustomerdetail.EmailAddress,
tblcustomerdetail.PhoneNumber
FROM tbluserlogindetail, tblcustomer, tblcustomerdetail
WHERE
tbluserlogindetail.LOginID = tblcustomer.CustomerID
AND tblcustomer.FedTaxID = tblcustomerdetail.FedTaxID
AND tbluserlogindetail.UserName LIKE 'pa%'
AND tbluserlogindetail.RoleTypeID = '20'
Try something like this.
Subqueries have a slow perfomance.
MySQL - SELECT WHERE field IN (subquery) - Extremely slow why?
