I am trying to get 5 latest order timings of customers using:
SET SESSION group_concat_max_len = 99;
select o.customer_id, substring_index(m.orders,',', 1) as order1,
(case when numc >=2 then substring_index(substring_index(m.orders, ',', 2), ',', -1)end) as order2,
(case when numc >=3 then substring_index(substring_index(m.orders, ',', 3), ',', -1)end) as order3,
(case when numc >=4 then substring_index(substring_index(m.orders, ',', 4), ',', -1)end) as order4,
(case when numc >=5 then substring_index(substring_index(m.orders, ',', 5), ',', -1)end) as order5
from orders o,
(select group_concat(date order by date desc) as orders, count(*) as numc
FROM orders) m
where country_id='27'
group by customer_id
But it is returning me sysdate for all customers.
Where am i doing it wrong?
I'm not sure what you mean by "sysdate for all customers". But, the join is not doing what you expect.
Just do the aggregation once:
select o.customer_id, substring_index(group_concat(date order by date desc),',', 1) as order1,
(case when count(*) >=2 then substring_index(substring_index(group_concat(date order by date desc), ',', 2), ',', -1)end) as order2,
(case when count(*) >=3 then substring_index(substring_index(group_concat(date order by date desc), ',', -1)end) as order3,
(case when count(*) >=4 then substring_index(substring_index(group_concat(date order by date desc), ',', 4), ',', -1)end) as order4,
(case when count(*) >=5 then substring_index(substring_index(group_concat(date order by date desc), ',', 5), ',', -1)end) as order5
from orders o
where country_id='27'
group by customer_id

you know that's wrong query for the median because median should be 1,5 not 2. where my wrong at in my median query?
You have ROUND() there to round the reported median to an integer. If you don't want that, remove it:
select max(itung), min(itung), format(avg(itung), 2), IF(count(*)%2 = 1, CAST(SUBSTRING_INDEX(SUBSTRING_INDEX( GROUP_CONCAT(itung ORDER BY itung SEPARATOR ',') , ',', 50/100 * COUNT(*)), ',', -1) AS DECIMAL), (CAST(SUBSTRING_INDEX(SUBSTRING_INDEX ( GROUP_CONCAT(itung ORDER BY itung SEPARATOR ','), ',', 50/100 * COUNT(*) + 1), ',', -1) AS DECIMAL) + CAST(SUBSTRING_INDEX(SUBSTRING_INDEX ( GROUP_CONCAT(itung ORDER BY itung SEPARATOR ','), ',', 50/100 * COUNT(*)), ',', -1) AS DECIMAL)) / 2) as median
or leave in the round and add a number of decimal places to round to, here 3:
select max(itung), min(itung), format(avg(itung), 2), IF(count(*)%2 = 1, CAST(SUBSTRING_INDEX(SUBSTRING_INDEX( GROUP_CONCAT(itung ORDER BY itung SEPARATOR ',') , ',', 50/100 * COUNT(*)), ',', -1) AS DECIMAL), ROUND((CAST(SUBSTRING_INDEX(SUBSTRING_INDEX ( GROUP_CONCAT(itung ORDER BY itung SEPARATOR ','), ',', 50/100 * COUNT(*) + 1), ',', -1) AS DECIMAL) + CAST(SUBSTRING_INDEX(SUBSTRING_INDEX ( GROUP_CONCAT(itung ORDER BY itung SEPARATOR ','), ',', 50/100 * COUNT(*)), ',', -1) AS DECIMAL)) / 2, 3)) as median
Be aware that looking up the median values from a GROUP_CONCAT comma-separated list of all the values only works if there are not too many rows, since GROUP_CONCAT will be truncated at ##group_concat_max_len, which defaults to 1024 characters on MySQL or on MariaDB before 10.2.
I am want to archive daily price statistics in MySQL 5.6 where I also use 25/50/75 percentiles. The formulas I found seem to work but are rounded to integers.
How can I get the 25/50/75 percentiles of price with 2 decimals precision?
INSERT INTO prices_daily

I have this query, works fine for view and csv export from phpmyadmin.
Is possible create a loop without repeat? thanks!

You can test this Query. It split a max. of 10 pieces from a row.

======================================
4 | 3 | 5
I want to display values like
column1 | column2
========================
level1 | 4
level2 | 3
level3 | 5
Please help me using mysql.
Crude way would be to use multiple unioned queries, something like this:-
SELECT 'level1' AS column1, SUBSTRING_INDEX(inter.CHR_SKILLLEVELS, ',', 1) AS column2
FROM hrm_t_interview inter
INNER JOIN
(
SELECT INT_APPLICANTID, 1 + LENGTH(CHR_SKILLLEVELS) - LENGTH(REPLACE(CHR_SKILLLEVELS, ',', '')) AS num_lines
FROM hrm_t_interview
GROUP BY INT_APPLICANTID
HAVING num_lines > 0
) temp
ON inter.INT_APPLICANTID = temp.INT_APPLICANTID
WHERE inter.INT_APPLICANTID=15
UNION
SELECT 'level2' AS column1, SUBSTRING_INDEX(SUBSTRING_INDEX(inter.CHR_SKILLLEVELS, ',', 2), ',', -1) AS column2
FROM hrm_t_interview inter
INNER JOIN
(
SELECT INT_APPLICANTID, 1 + LENGTH(CHR_SKILLLEVELS) - LENGTH(REPLACE(CHR_SKILLLEVELS, ',', '')) AS num_lines
FROM hrm_t_interview
GROUP BY INT_APPLICANTID
HAVING num_lines > 1
) temp
ON inter.INT_APPLICANTID = temp.INT_APPLICANTID
WHERE inter.INT_APPLICANTID=15
UNION
SELECT 'level3' AS column1, SUBSTRING_INDEX(SUBSTRING_INDEX(inter.CHR_SKILLLEVELS, ',', 3), ',', -1) AS column2
FROM hrm_t_interview inter
INNER JOIN
(
SELECT INT_APPLICANTID, 1 + LENGTH(CHR_SKILLLEVELS) - LENGTH(REPLACE(CHR_SKILLLEVELS, ',', '')) AS num_lines
FROM hrm_t_interview
GROUP BY INT_APPLICANTID
HAVING num_lines > 2
) temp
ON inter.INT_APPLICANTID = temp.INT_APPLICANTID
WHERE inter.INT_APPLICANTID=15
UNION
SELECT 'level4' AS column1, SUBSTRING_INDEX(SUBSTRING_INDEX(inter.CHR_SKILLLEVELS, ',', 4), ',', -1) AS column2
FROM hrm_t_interview inter
INNER JOIN
(
SELECT INT_APPLICANTID, 1 + LENGTH(CHR_SKILLLEVELS) - LENGTH(REPLACE(CHR_SKILLLEVELS, ',', '')) AS num_lines
FROM hrm_t_interview
GROUP BY INT_APPLICANTID
HAVING num_lines > 3
) temp
ON inter.INT_APPLICANTID = temp.INT_APPLICANTID
WHERE inter.INT_APPLICANTID=15
UNION
SELECT 'level5' AS column1, SUBSTRING_INDEX(SUBSTRING_INDEX(inter.CHR_SKILLLEVELS, ',', 5), ',', -1) AS column2
FROM hrm_t_interview inter
INNER JOIN
(
SELECT INT_APPLICANTID, 1 + LENGTH(CHR_SKILLLEVELS) - LENGTH(REPLACE(CHR_SKILLLEVELS, ',', '')) AS num_lines
FROM hrm_t_interview
GROUP BY INT_APPLICANTID
HAVING num_lines > 4
) temp
ON inter.INT_APPLICANTID = temp.INT_APPLICANTID
WHERE inter.INT_APPLICANTID=15
A bit more elegant might be to generate a range of rows, one for each possible delimited value.
Not tested but something like this:-
SELECT CONCAT('level', temp2.iCnt) AS column1, SUBSTRING_INDEX(SUBSTRING_INDEX(inter.CHR_SKILLLEVELS, ',', temp2.iCnt), ',', -1) AS column2
FROM hrm_t_interview inter
INNER JOIN
(
SELECT 1 + LENGTH(CHR_SKILLLEVELS) - LENGTH(REPLACE(CHR_SKILLLEVELS, ',', '')) AS num_lines
FROM hrm_t_interview
GROUP BY INT_APPLICANTID
) temp
ON inter.INT_APPLICANTID = temp.INT_APPLICANTID
INNER JOIN
(
SELECT 0 AS iCnt UNION SELECT 1 UNION SELECT 2 UNION SELECT 3 UNION SELECT 4
) temp2
ON temp.num_lines >= temp2.iCnt
WHERE inter.INT_APPLICANTID=15
If you can paste up some test data I will check the sql.
I am trying to divide data in one onf the tables on my MySQL database.
Column contains data like this:
de:"Sweatjacke*";en:"jacket*";pl:"bluza*";
de:"*";en:"*";pl:"bluza*";
fr:"*";de:"*";en:"*";pl:"dres junior*";cz:"*";
pl:"bluza";
And I am trying to divide all of the translations into separate columns. Already came with solution to do this by using:
SELECT
SUBSTRING_INDEX(SUBSTRING_INDEX(name, ';', 1), ';', -1) as tr1,
SUBSTRING_INDEX(SUBSTRING_INDEX(name, ';', 2), ';', -1) as tr2,
SUBSTRING_INDEX(SUBSTRING_INDEX(name, ';', 3), ';', -1) as tr3,
SUBSTRING_INDEX(SUBSTRING_INDEX(name, ';', 4), ';', -1) as tr4,
SUBSTRING_INDEX(SUBSTRING_INDEX(name, ';', 5), ';', -1) as tr5
FROM product;
statement, but that results in:
tr1 tr2 tr3 tr4 tr5
fr:"*" de:"*" en:"*" pl:"bluza*" cz:"*"
fr:"*" de:"Sweatjacke*" en:"jacket*" pl:"bluza*" cz:"*"
de:"Sweatjacke*" en:"jacket*" pl:"bluza*"
And I want to have the results gruped by translation type (pl/de/en) so in each collumn one type of translatoin is present. For example in column1 = pl:, column2 = en: etc.
Any one came across similar problem and knows a way to solve it?
You need to unpivot the data, then select the first and second part of each value and then re-aggregate it.
However, a better form for the data is really to have language/translation. The following produces this:
select substring_index(tr, ':', 1) as l, substring_index(tr, ':', 2) as t, name
from (select SUBSTRING_INDEX(SUBSTRING_INDEX(name, ';', n.n), ';', -1) as tr, n, name
from product p cross join
(select 1 as n union all select 2 union all select 3 union all select 4 union all
select 5
) n
) n
You would probably want an "id" column or "word" column to identify each row, rather than the name column.
You can now pivot this result to get what you want:
select max(case when l = 'en' then name end) as en,
max(case when l = 'fr' then name end) as fr,
max(case when l = 'de' then name end) as de,
max(case when l = 'pl' then name end) as pl,
max(case when l = 'cz' then name end) as cz
from (select substring_index(tr, ':', 1) as l, substring_index(tr, ':', 2) as t, name
from (select SUBSTRING_INDEX(SUBSTRING_INDEX(name, ';', n.n), ';', -1) as tr, n, name
from product p cross join
(select 1 as n union all select 2 union all select 3 union all select 4 union all
select 5
) n
) n
) lt
group by name;
Managed to solve it by using some of the string related functions funcitons:
SELECT
SUBSTRING_INDEX( SUBSTRING( name, LOCATE( "pl:", name ) , 150 ) , ';', 1 ) AS pl,
SUBSTRING_INDEX( SUBSTRING( name, LOCATE( "en:", name ) , 150 ) , ';', 1 ) AS en,
SUBSTRING_INDEX( SUBSTRING( name, LOCATE( "de:", name ) , 150 ) , ';', 1 ) AS de,
SUBSTRING_INDEX( SUBSTRING( name, LOCATE( "fr:", name ) , 150 ) , ';', 1 ) AS fr
FROM product
Thanks to everyone for help.
As far as I understand you want to UNPIVOT your data. There is no such function in MySQL, so you might want to export your data into MSSQL (you can use free MSSQL Express) and use UNPIVOT function: http://technet.microsoft.com/en-us/library/ms177410(v=sql.105).aspx
