Below is the code failing in Hive:
(Alias at 6:5 (END) is not recognized)
INSERT INTO WRKT_REGULATORY_COMPONE_RECLASS
select
case
when WRKT_REGULATORY_COMPONENT_FINAL.REVENUE_FLAG != 'Y'
AND WRKT_REGULATORY_COMPONENT_FINAL.EXCLUDED_FLAG = 'Y'
THEN WRKT_REGULATORY_COMPONE_RECLASS.EXECUTION_ORDER = '1'
END
FROM WRKT_REGULATORY_COMPONENT_FINAL
this one: THEN WRKT_REGULATORY_COMPONE_RECLASS.EXECUTION_ORDER = '1' is wrong
after THEN it should be literal 1 or column

I have table like this, and i want to output the result like output table, can anyone tell me how to do it, in MySQL
You can use left join like so :
SELECT tb_session.SESSION AS SESSION, tb_class.CLASS AS CLASS from tb_schedul LEFT JOIN tb_session ON tb_schedule.ID_SESSION = tb_session.ID LEFT JOIN tb_schedul.ID_CLASS = tb_class.ID
Good morning, you can use LEFT JOIN
try it:
SELECT tb_session.SESSION, tb_schedul.ID_CLASS FROM tb_session LEFT JOIN tb_schedul
ON tb_session.ID = tb_schedul.ID_SESSION;

I have a table in SQL Server where a row contains a Json column - something like this:
ResponseText
RequestId
{"LosUnqCod":0,"LosMidId":23}
96173722
{"LosUnqCod":1,"LosMidId":5}
96173721
I want to have a table in this shape:
LosUnqCod
LosMidId
RequestId
0
23
96173722
1
5
96173721
how to open this json?
Hi every body I found my answer and want to share with anyone who has the same issue as I does
SELECT
reqTbl.LosUnqCod ,
a.RequestId
FROM [dbo].[a] CROSS APPLY
OPENJSON( dbo.a.responsetext)
WITH (
LosUnqCod nvarchar(50)
) AS reqTbl
You don't have to use OPENJSON if you only have one JSON object (not an array) per SQL row, you can use JSON_VALUE instead:
SELECT
JSON_VALUE(a.responsetext, '$.LosUnqCod') LosUnqCod,
JSON_VALUE(a.responsetext, '$.LosMidId') LosMidId,
a.RequestId
FROM [dbo].[a];

i have a database (mysql) with links like:
mysite.com/Movies/Abajan_1080p.mp4
mysite.com/Movies/Abajan_720p.mp4
mysite.com/Movies/Abajan_480p.mp4
mysite.com/Movies/Bahman_1080p.mp4
mysite.com/Movies/Bahman_720p.mp4
mysite.com/Movies/Bahman_480p.mp4
....
i sorted my files by creating directories by alphabets (A,B,...)
so i need to change links:
mysite.com/Movies/A/Abajan_1080p.mp4
mysite.com/Movies/A/Abajan_720p.mp4
mysite.com/Movies/A/Abajan_480p.mp4
mysite.com/Movies/B/Bahman_1080p.mp4
mysite.com/Movies/B/Bahman_720p.mp4
mysite.com/Movies/B/Bahman_480p.mp4
is there a simple solution to edit database? to edit all links like that?
Thanks a lot
You can use the function SUBSTRING_INDEX() to get the filename and then concatenate the path:
UPDATE tablename
SET col = CONCAT(
'mysite.com/Movies/',
LEFT(SUBSTRING_INDEX(col, '/', -1), 1),
'/',
SUBSTRING_INDEX(col, '/', -1)
)
Replace col with your column's name.
See the demo.
Results:
col
mysite.com/Movies/A/Abajan_1080p.mp4
mysite.com/Movies/A/Abajan_720p.mp4
mysite.com/Movies/A/Abajan_480p.mp4
mysite.com/Movies/B/Bahman_1080p.mp4
mysite.com/Movies/B/Bahman_720p.mp4
mysite.com/Movies/B/Bahman_480p.mp4

I need to write a query which need to replace email result by 0 when it's null
UPDATE tblName SET email = 0 WHERE email is null;
Use the ifnull() function:
ifnull(email,"0")
You can use the coalesce function:
SELECT COALESCE(email, '0') FROM some_table

I have 3 mysql queries in php (one for each category/widget), all 3 queries together should output 3 * 6 = 18 results. So if one query returns less, more results from the other queries should be used.
How can i do that? Thanks.
Instantiate 2 variables , keep count of selected rows and execute query using these counters
for example this will be your first query execiton
$default = 6;
$limit= $default;
$some_result = mysql("SELECT * FROM table LIMIT $limit");
then you can use this for every query-limit
$limit = $limit - count($some_result) + $default;
