I hope this can clearly explain what I am looking for. I have searched read through a few articles on this site, but haven't found what I am looking for. I have also spent close to 3 hours trying to figure this out on my own.
I am trying to count the number of records and SUM the WorkTime. Here is my query I have been working with.
SELECT Log.User
, sum(if(hour(endtime) = 0, 1, 0)) AS Midnight
, sum(if(hour(endtime) = 1, 1, 0)) AS `1AM`
, sum(if(hour(endtime) = 2, 1, 0)) AS `2AM`
, sum(if(hour(endtime) = 3, 1, 0)) AS `3AM`
, sum(if(hour(endtime) = 4, 1, 0)) AS `4AM`
, sum(if(hour(endtime) = 5, 1, 0)) AS `5AM`
, sum(if(hour(endtime) = 6, 1, 0)) AS `6AM`
, sum(if(hour(endtime) = 7, 1, 0)) AS `7AM`
, sum(if(hour(endtime) = 8, 1, 0)) AS `8AM`
, sum(if(hour(endtime) = 9, 1, 0)) AS `9AM`
, sum(if(hour(endtime) = 10, 1, 0)) AS `10AM`
, sum(if(hour(endtime) = 11, 1, 0)) AS `11AM`
, sum(if(hour(endtime) = 12, 1, 0)) AS `12PM`
, sum(if(hour(endtime) = 13, 1, 0)) AS `1PM`
, sum(if(hour(endtime) = 14, 1, 0)) AS `2PM`
, sum(if(hour(endtime) = 15, 1, 0)) AS `3PM`
, sum(if(hour(endtime) = 16, 1, 0)) AS `4PM`
, sum(if(hour(endtime) = 17, 1, 0)) AS `5PM`
, sum(if(hour(endtime) = 18, 1, 0)) AS `6PM`
, sum(if(hour(endtime) = 19, 1, 0)) AS `7PM`
, sum(if(hour(endtime) = 20, 1, 0)) AS `8PM`
, if(hour(endtime) = 20, sec_to_time(sum(time_to_sec(endtime) - time_to_sec(starttime))), 0) AS `8PM Time`
, sum(if(hour(endtime) = 21, 1, 0)) AS `9PM`
, sum(if(hour(endtime) = 22, 1, 0)) AS `10PM`
, sum(if(hour(endtime) = 23, 1, 0)) AS `11PM`
FROM
(
SELECT user
, controlnumber
, starttime
, endtime
, timediff(endtime, starttime) AS Worktime
FROM
atrtaxcert.ordertimeworked
) AS Log
GROUP BY
Log.User;
These start and end times are only minutes apart.
Any guidance is much appreciated. This is my first post here, and was not able to provide any images to help describe.
If starttime and endtime are TIME datatypes, then use the TIME_TO_SEC function and do a subtraction. Total up the seconds, and then convert the total to a string representation.
SELECT `Log`.`User`
, ...
, SUM(HOUR(`Log`.endtime)=20) AS `8PM_count`
, SUM(IF(HOUR(`Log`.endtime)=20,work_seconds,0) AS `8PM_seconds`
, SEC_TO_TIME(SUM(IF(HOUR(`Log`.endtime)=20,`Log`.work_seconds,0) AS `8PM_hhhmmss`
, ...
FROM ( SELECT
, TIME_TO_SEC(endtime)-TIME_TO_SEC(starttime) AS work_seconds
) `Log`
GROUP
BY `Log`.`User`
NOTE: this:
SELECT HOUR(endtime)=0 AS foo
is shorthand equivalent to
SELECT IF(HOUR(endtime) = 0, 1, 0) AS foo
If starttime and endtime are DATETIME values, the you can use the TIMESTAMPDIFF function to calculate the difference in seconds:
SELECT `Log`.`User`
, ...
, SUM(HOUR(`Log`.endtime)=20) AS `8PM_count`
, SUM(IF(HOUR(endtime)=20,TIMESTAMPDIFF(SECOND,`Log`.starttime,`Log`.endtime),0) AS `8PM_seconds`
, ...
FROM (
) `Log`
GROUP
BY `Log`.`User`
(You probably want to ignore the values returned when e.g. starttime = '23:59:00' and endtime = '00:01:00', and that would require another conditional test.)

I have a table of sales in MySQL. I'm trying in 1 query to get a view that looks like this:
AGENT, MONDAY_TOTAL, TUESDAY_TOTAL,WEDNESDAY_TOTAL,THURSDAY_TOTAL,FRIDAY_TOTAL,SATURDAY_TOTAL
What I have so far is this:
SELECT DISTINCT(repname), DAYOFWEEK(sub_date), COUNT(*)
FROM `NewDeals`
WHERE WEEK(sub_date) = WEEK(CURRENT_DATE)
GROUP BY repname, DAYOFWEEK(sub_date)
That gives me values that look like this:
AGENT, DAYOFWEEK, TOTAL
Naturally, I can turn the output of the second example into the first in my code, but if I can just do it with the SQL query I'd rather do that.
SELECT repname,
SUM(IF(DAYOFWEEK(sub_date)=2, 1, 0)) AS MONDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=3, 1, 0)) AS TUESDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=4, 1, 0)) AS WEDNESDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=5, 1, 0)) AS THURSDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=6, 1, 0)) AS FRIDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=7, 1, 0)) AS SATURDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=1, 1, 0)) AS SUNDAY_TOTAL
FROM `NewDeals`
WHERE WEEK(sub_date) = WEEK(CURRENT_DATE)
GROUP BY repname
But getting results for days that haven't happened yet.
Update: This was because we did not constrain the year:
Solution:
SELECT repname,
SUM(IF(DAYOFWEEK(sub_date)=2, 1, 0)) AS MONDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=3, 1, 0)) AS TUESDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=4, 1, 0)) AS WEDNESDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=5, 1, 0)) AS THURSDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=6, 1, 0)) AS FRIDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=7, 1, 0)) AS SATURDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=1, 1, 0)) AS SUNDAY_TOTAL
FROM `NewDeals`
WHERE WEEK(sub_date) = WEEK(CURRENT_DATE) AND YEAR(sub_date) = YEAR(CURRENT_DATE)
GROUP BY repname
You can use an IF function to select only DAYOFWEEK-related counts, then sum every counted element inside the SUM aggregate function as follows:
SELECT repname,
SUM(IF(DAYOFWEEK(sub_date)=2, 1, 0)) AS MONDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=3, 1, 0)) AS TUESDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=4, 1, 0)) AS WEDNESDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=5, 1, 0)) AS THURSDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=6, 1, 0)) AS FRIDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=7, 1, 0)) AS SATURDAY_TOTAL,
SUM(IF(DAYOFWEEK(sub_date)=1, 1, 0)) AS SUNDAY_TOTAL
FROM `NewDeals`
WHERE WEEK(sub_date) = WEEK(CURRENT_DATE)
GROUP BY repname
Note: when the DISTINCT keyword is applied, it will work on every selected field of your SELECT clause, you can't make a distinct of a single field using parentheses.
I have a simple query that produces the below results:
SELECT month,transporttype,count(transporttype) as loads
from deliveries
group by month,transporttype
I would like to transpose the rows into columns.
I understand mysql does not have pivot functions so a union is required but not 100% sure.
Thanks in advance for the help.
You can do it with a crosstab like this -
SELECT
`year`,
`month`,
SUM(IF(`transporttype` = 'inbound', 1, 0)) AS `inbound`,
SUM(IF(`transporttype` = 'LocalPMB', 1, 0)) AS `LocalPMB`,
SUM(IF(`transporttype` = 'Long Distance', 1, 0)) AS `Long Distance`,
SUM(IF(`transporttype` = 'shuttle', 1, 0)) AS `shuttle`,
SUM(IF(`transporttype` = 'export', 1, 0)) AS `export`,
SUM(IF(`transporttype` = 'Extrusions-LongDistance', 1, 0)) AS `Extrusions-LongDistance`,
SUM(IF(`transporttype` = 'Extrusions-Shuttle', 1, 0)) AS `Extrusions-Shuttle`
FROM `deliveries`
GROUP BY `year`, `month`
On a different note, you should move transporttype values to a lookup table and have transporttype_id in this table.
I have the following query which returns rows grouped.
For the column mc_name which returns a NULL value, is there any way to set a value without changing records data?
This is the query:

SUM(IF(month(properties.created_at) = 11, 1, 0)) as NOV,
SUM(IF(month(properties.created_at) = 12, 1, 0)) as DIC,
COUNT(PROPERTIES.PROP_EXCLUSIVE) AS TOTAL
from

left join `megaagents` on `properties`.`megaagent_id` = `megaagents`.`id`
where
`properties`.`marketcenter_id` = 11
and `properties`.`prop_exclusive` in ('No Exclusiva', 'Exclusiva')
and `properties`.`prop_transaction` in ('Alquiler Temporal', 'Alquiler', 'Venta')
group by
`megaagents`.`megaagent_name`
order by
`megaagents`.`megaagent_name` asc
Regards!
Use COALESCE():
select
coalesce(megaagents.megaagent_name, 'custom value') AS mc_name,

I have written a query which consists of multiple joins and sum(if()) condition.
I am using MySql Database.
The query structure seems like this:
*The query joins from multiple tables(7 to be precise) and the sum(if()) conditions is to represent total 53 states of US.*It takes almost 20 minutes for the query to execute which is a very long period.
If anyone could suggest how can I reduce this large amount of time.

We must alter database index for performance.
we must the run the below sql query in the database first.

I am trying to add a column "wOBA" to a table "starting_pitcher_stats" in MySQL using sequel-pro. Below is the code for a function that performs arithmetic operations on nine variables in the "starting_pitcher_stats" table. In particular, the function gathers the values for a number of variables, applies different weights (coefficients) to some of them (numerator below) and divides that sum by the addition and subtraction of a few more variables. All of these variables reside in the "starting_pitcher_stats" table. The arithmetic operations are expressed in the below formula (the coefficients are the values that are multiplied by each of the variables in numerator below):
wOBA=(.69*walks_a + .72*HBP + .89*singles_a + 1.27*doubles_a + 1.62*triples_a+ 2.10*HR_a)/(at_bats+walks_a+SF+HBP)
Each weight varies by year. The different weights for each year come from the table "GUTS".
The first dilemma I'm having is getting the correct code for the function. The second is the correct code syntax to use to actually call up this function and populate the new column with correct weighted wOBA values for each game of each year(season) for each "Starting_Pitcher".
The function is created with the code below and is listed as a function "wOBA" in my list of functions and procedures. However, the little wheel/knob next to the function name in sequel pro is greyed-out for some reason. It's not until I find out the correct code to invoke it, that I'll know if there are any errors.
Please ask for any more information that I can provide to clarify anything.
Thank you in advance.

We'll start by cleaning up the query. You should always try to perform your calculations across each row when possible rather than performing multiple vertical subqueries, as this avoids the DBMS making multiple passes over the same table.
SELECT
(
( (g.wbb * SUM(IF(e.event_cd = 14, 1, 0)))
+ (g.whbp * SUM(IF(e.event_cd = 16, 1, 0)))
+ (g.w1b * SUM(IF(e.event_cd = 20, 1, 0)))
+ (g.w2b * SUM(IF(e.event_cd = 21, 1, 0)))
+ (g.w3b * SUM(IF(e.event_cd = 22, 1, 0)))
+ (g.whr * SUM(IF(e.event_cd = 23, 1, 0)))
)
/
(
SUM(IF(e.ab_fl = 'T', 1, 0))
+ SUM(IF(e.event_cd = 14, 1, 0))
+ SUM(IF(e.sf_fl = 'T', 1, 0))
+ SUM(IF(e.event_cd = 16, 1, 0))
)
) AS woba
FROM events e, guts g
WHERE e.year_id = g.season_id
AND e.pit_start_fl = 'T'
AND e.pit_id = starting_pitcher
GROUP BY g.season;
Assuming I haven't dropped a comma somewhere, this will return a column woba for each year for the specified starting pitcher.
Note that I've joined the tables on e.year_id instead of SUBSTRING(e.game_ID,4,4); this avoids the overhead of calling SUBSTRING() on each record. This sort of thing seems minor, but it can add up quickly over a large table.
That should be enough to get you started.
