How to join next_run_date and next_run_time together as a single column?
My Query used in SSRS 2008
SELECT c.Name AS ReportName,[LastRunTime],
'Next Run Date' = CASE next_run_date WHEN 0 THEN null ELSE
substring(convert(varchar(15),next_run_date),1,4) + '/' +
substring(convert(varchar(15),next_run_date),5,2) + '/' +
substring(convert(varchar(15),next_run_date),7,2)
END,
--Need to add next_run_date_Time here
FROM
dbo.[Catalog] c
INNER JOIN dbo.[Subscriptions] S ON c.ItemID = S.Report_OID
INNER JOIN dbo.ReportSchedule R ON S.SubscriptionID = R.SubscriptionID
INNER JOIN msdb.dbo.sysjobs J ON Convert(nvarchar(128),R.ScheduleID) = J.name
INNER JOIN msdb.dbo.sysjobschedules JS ON J.job_id = JS.job_id
ORDER BY S.LastRunTime DESC

Answer 1

Assuming both are varchar, try this:
SELECT schedule_id, job_id,
CONVERT(datetime, next_run_date, 112)
+ CONVERT(time,
SUBSTRING(next_run_time, 1, LEN(next_run_time) - 4) + ':'
+ LEFT(RIGHT(next_run_time, 4), 2) + ':'
+ RIGHT(next_run_time, 2),
114) AS next_run_date_Time
FROM my_table
Here is a fiddle
If those fields are numbers, you can convert them in a sub-query first and then apply the same query above:
SELECT schedule_id, job_id,
CONVERT(datetime, next_run_date, 112)
+ CONVERT(time,
SUBSTRING(next_run_time, 1, LEN(next_run_time) - 4) + ':'
+ LEFT(RIGHT(next_run_time, 4), 2) + ':'
+ RIGHT(next_run_time, 2),
114) AS next_run_date_Time
FROM (SELECT schedule_id, job_id
, CAST(next_run_date AS VARCHAR(8)) AS next_run_date
, CAST(next_run_time AS VARCHAR(6)) AS next_run_time
FROM my_table) AS t
Here is a fiddle
EDIT you can update your query to use this concept like this:
SELECT c.Name AS ReportName,[LastRunTime],
CONVERT(datetime, next_run_date, 112)
+ CONVERT(time,
SUBSTRING(next_run_time, 1, LEN(next_run_time) - 4) + ':'
+ LEFT(RIGHT(next_run_time, 4), 2) + ':'
+ RIGHT(next_run_time, 2),
114) AS 'Next Run Date'
FROM
dbo.[Catalog] c
INNER JOIN dbo.[Subscriptions] S ON c.ItemID = S.Report_OID
INNER JOIN dbo.ReportSchedule R ON S.SubscriptionID = R.SubscriptionID
INNER JOIN msdb.dbo.sysjobs J ON Convert(nvarchar(128),R.ScheduleID) = J.name
INNER JOIN (SELECT schedule_id, job_id
, CAST(next_run_date AS VARCHAR(8)) AS next_run_date
, CAST(next_run_time AS VARCHAR(6)) AS next_run_time
FROM msdb.dbo.sysjobschedules) AS JS ON J.job_id = JS.job_id
ORDER BY S.LastRunTime DESC

Answer 2

Here is one way to do it:
-- Create sample table and data
CREATE TABLE tbl (
next_run_date char(8),
next_run_time varchar(6)
)
INSERT INTO tbl VALUES
(20151005, 93020),
(20151001, 170000)
using cte1 to pad next_run_time with a leading zero if needed,
and using cte2 to break the string to a "normal" time representation:
;with cte1 as
(
select next_run_date,
right('000000'+ next_run_time, 6) as run_time_base
FROM tbl
), cte2 as
(
select next_run_date,
left(run_time_base, 2) + ':' +
substring(run_time_base, 3, 2) + ':' +
right(run_time_base, 2) as run_time
from cte1
)
select cast(next_run_date as datetime) + cast(run_time as datetime) as run_datetime
from cte2
-- clean up
drop table tbl
Results:
run_datetime

Answer 3

I am assuming here that next_run_date & next_run_time, I have written query here which will give your desired output..
select
schedule_id
,job_id
,convert(datetime,
convert(varchar, convert(datetime, next_run_date, 112), 111)
+ ' ' + substring(REPLICATE('0',6-LEN(next_run_time)) + next_run_time, 1, 2)
+ ':' + substring(REPLICATE('0',6-LEN(next_run_time)) + next_run_time, 3, 2)
+ ':' + substring(REPLICATE('0',6-LEN(next_run_time)) + next_run_time, 5, 2)
) as next_run_date_Time
from TableName
Here is the sql fiddle

Answer 4

I think the simplest option, assuming both are varchars to begin with, is:
dateadd(HH, cast(left(time, len(time) - 4) as int), cast(date as datetime))
Convert the varchar date to a datetime format, which will default to midnight on the date, then add the number of hours specified by the time. The syntax above assumes times are always on the hour - if not, add minutes as necessary.
Once in datetime, you can use convert to specify any display format you like.
