Find difference of two time in sql query - sql-server

I have One Table DailyPerformanceReport(with Two Time Columns) with data like this in SQL Server 2008R2
i want to get difference of InPunch and OutPunch as WorkHRs(in Time format).Myexpected output

Try this:
SAMPLE DATA
CREATE TABLE DailyPerformanceReport(
InPunch TIME,
OutPunch TIME
)
INSERT INTO DailyPerformanceReport VALUES
('09:14:00', '19:22:00'),
('09:54:00', '19:37:00'),
('09:14:00', '18:39:00');
QUERY
SELECT
*,
WorkHRS = CAST(DATEADD(MILLISECOND, DATEDIFF(MILLISECOND, InPunch, OutPunch), 0) AS TIME)
FROM DailyPerformanceReport
RESULT
InPunch OutPunch WorkHRS
---------------- ---------------- ----------------
09:14:00.0000000 19:22:00.0000000 10:08:00.0000000
09:54:00.0000000 19:37:00.0000000 09:43:00.0000000
09:14:00.0000000 18:39:00.0000000 09:25:00.0000000

You can try with the datediff functionality.
select DATEDIFF(MINUTE ,'value1',DateAdd(day, 1, 'value2'))

Microsoft SQL Server: wrong query execution plan taking too long

This is on Windows SQL Server Cluster.
Query is coming from 3rd party application so I can not modify the query permanently.
Query is:
DECLARE #FromBrCode INT = 1001
DECLARE #ToBrCode INT = 1637
DECLARE #Cdate DATE = '31-mar-2017'
SELECT
a.PrdCd, a.Name, SUM(b.Balance4) as Balance
FROM
D009021 a, D010014 b
WHERE
a.PrdCd = LTRIM(RTRIM(SUBSTRING(b.PrdAcctId, 1, 8)))
AND substring(b.PrdAcctId, 9, 24) = '000000000000000000000000'
AND a.LBrCode = b.LBrCode
AND a.LBrCode BETWEEN #FromBrCode AND #ToBrCode
AND b.CblDate = (SELECT MAX(c.CblDate)
FROM D010014 c
WHERE c.PrdAcctId = b.PrdAcctId
AND c.LBrCode = b.LBrCode
AND c.CblDate <= #Cdate)
GROUP BY
a.PrdCd, a.Name
HAVING
SUM(b.Balance4) <> 0
ORDER BY
a.PrdCd
This particular query is taking too much time to complete execution. The same problem happens on a different SQL Server.
No table lock was found, processor and memory usage is normal while the query is running.
Normal "select top 1000" working and showing output instantly in both tables (D009021, D010014)
Reindex and rebuild / update stats done in both tables but problem did not resolve (D009021, D010014)
The same query is working if we reduce number of branch but slowly
(
DECLARE #FromBrCode INT =1001
DECLARE #ToBrCode INT =1001
)
The same query is working faster giving output within 2 mins if we replace any one variable and use the value directly
AND a.LBrCode BETWEEN #FromBrCode AND #ToBrCode
changed to
AND a.LBrCode BETWEEN 1001 AND #ToBrCode
The same query is working faster and giving output within 2 mins if we add "OPTION (RECOMPILE)" at end
I tried to clean cache query execution plan and optimized new one but problem still exists
Found that the query estimate plan and actual execution plan are different (see screenshots)
Table D010014 is aliased twice once as b and once as c
the they are joined to the same table.
Try toto remove the sub query below and create a temp table to store
the values you need. I added * to the fields you self join
SELECT MAX(c.CblDate)
FROM D010014 c
WHERE c.PrdAcctId = b.PrdAcctId
AND c.LBrCode = b.LBrCode
AND c.CblDate <= #Cdate
if you cant do that then try
SELECT TOP 1 c.CblDate
FROM D010014 c
WHERE c.PrdAcctId = b.PrdAcctId
AND c.LBrCode = b.LBrCode
AND c.CblDate <= #Cdate
ORDER BY c.CblDate DESC

SQL Server - How to Use Merge Statement for Slowly Changing Dimension with More Than Two Conditions?

I am trying to implement Slowly Changing Dimension Type 2 through T-SQL but I can't figure out how to put a request to work.
Table columns: cpf, nome, telefone_update, endereco_insert
Basically the logic is: if the MATCH doesn't happen using cpf, then the record must be inserted; if the MATCH happens but only the telefone_update field has changed, there is no need to another record and I just want to UPDATE and override the values; if the MATCH happens but only the endereco_insert field has changed I want to add a new record and update the start and end dates.
What I have so far is:
insert into #dm_lucas_tst (
[cpf],
[nome],
[telefone_update],
[endereco_insert],
[dt_scd_start],
[dt_scd_end],
[nu_scd_version]
)
select [cpf],
[nome],
[telefone_update],
[endereco_insert],
cast(dateadd(month, datediff(month, 0, getdate()), 0) as date) as [dt_scd_start],
'2199-12-31' AS [dt_scd_end],
1 AS [nu_scd_version]
from (
merge edw.dim.dm_lucas_tst as Target
using edw.dim.stg_lucas_tst as Source
on Target.cpf = Source.cpf
when not matched by target
then
insert (
[cpf],
[nome],
[telefone_update],
[endereco_insert],
[dt_scd_start],
[dt_scd_end],
[nu_scd_version]
)
values (
Source.[cpf],
Source.[nome],
Source.[telefone_update],
Source.[endereco_insert],
cast(dateadd(month, datediff(month, 0, getdate()), 0) as date),
'2199-12-31',
1
)
when matched
and Source.telefone_update <> Target.telefone_update
and Target.dt_scd_end = '2199-12-31'
then
update set telefone_update = Source.telefone_update
output $ACTION ActionOut,
Source.[cpf],
Source.[nome],
Source.[telefone_update],
Source.[endereco_insert]
) AS MergeOut
where MergeOut.ActionOut = 'UPDATE';
But I don't think putting another WHEN MATCH AND ... will make that work.
Any suggestions?
Thanks in advance!
Accordingly to your description, I'm assuming that you need:
SCD Type 1 for column [telefone_update]
SCD Type 2 for column [endereco_insert]
I've used application SCD Merge Wizard to easily create described logic.
When I made tests for it - everything looks as expected, I guess.
I described the process on my blog - please have a look and tell me if that was exactly what you wanted?

Convert Statement to Crystal Reports SQL Expression

I have a SQL command that works great in SQL Server. Here's the query:
SELECT TOP 1000
(
SELECT COUNT(LINENUM)
FROM OEORDD D1
WHERE D1.ORDUNIQ = OEORDD.ORDUNIQ
)
- (SELECT COUNT(LINENUM)
FROM OEORDD D1
WHERE D1.ORDUNIQ = OEORDD.ORDUNIQ
AND D1.LINENUM > OEORDD.LINENUM)
FROM OEORDD
ORDER BY ORDUNIQ, LINENUM
The query looks at the total lines on an order, then looks at the current "LINENUM" field. With the value of the LINENUM field, it looks to see how many lines have a greater LINENUM value on the order and subtracts it from the number of lines on an order to get the correct Line number.
When I try to add it as a SQL expression in version 14.0.2.364 as follows:
(
(
SELECT COUNT("OEORDD"."LINENUM")
FROM "OEORDD" "D1"
WHERE "D1"."ORDUNIQ" = "OEORDD"."ORDUNIQ"
)
- (SELECT COUNT("OEORDD"."LINENUM")
FROM "OEORDD" "D1"
WHERE "D1"."ORDUNIQ" = "OEORDD"."ORDUNIQ"
AND "D1"."LINENUM" > "OEORDD"."LINENUM"
)
)
I get the error "Column 'SAMDB.dbo.OEORDD.ORDUNIQ' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause.
If I try to add GROUP BY "OEORDD"."ORDUNIQ" at the end, I get "Incorrect syntax near the keyword 'GROUP'. I've tried adding "FROM OEORDD" at the end of query and it errors out on the word "FROM". I have the correct tables linked in the Database Expert.
EDIT --------------
I was able to get the first query working by getting rid of the alias, it's as follows:
(
SELECT COUNT(LINENUM)
FROM OEORDD
WHERE OEORDH.ORDUNIQ=OEORDD.ORDUNIQ)
)
However, I believe I need to use the alias in the second query to compare line numbers. I'm still stuck on that one.

Update query failed '0' rows affected

I am trying to run this query but the query keeps giving up on me:
Update StockInvoiceInfo set Quantity = Quantity - 2 where p_id = 5 AND ProductDate = convert(Cast('31-5-2015' as datetime)) ;
After Running this code it returns an error below:
Incorrect syntax near '31-5-2015'
The datatype of the ProductDate column isDate. I am using Sql Server 2012.
You have used Convert functions but didn't supplied it with parameters. Also there is no need for this function here. Also take care of date format. I have changed it to standard format:
Update StockInvoiceInfo set Quantity = Quantity - 2
where p_id = 5 AND ProductDate = Cast('2015-05-31' as datetime)
If all you are trying to do is compare a Sql Date, then just use an agnostic format like '20150531' or easier to read '2015-05-31'. No need for casts or convert at all, i.e.
WHERE ... AND ProductDate = '2015-05-31'
However, if ProductDate isn't a date, but one of the *DATETIME* data types, and you are looking to update any time on the same day, then I believe you are looking for something like:
Update StockInvoiceInfo
set Quantity = Quantity - 2
where
p_id = 5
AND CAST(ProductDate AS DATE) = '2015-05-31';
However, the performance will be lousy as the clause isn't likely to be SARGable. You're better off simply doing:
AND ProductDate >= '2015-05-31' AND ProductDate < '2015-06-01';
(Resist the temptation to use between, or hacks like ':23:59:59' as there will be data corner cases which will bite you)
use CAST('5-31-2015' as DATETIME)
with the above update statement you started convert but with incomplete syntax
here the convert syntax
Update StockInvoiceInfo
set Quantity = Quantity - 2
where p_id = 5
AND ProductDate = convert(datetime,Cast('31-5-2015' as varchar),103) ;

Oracle split text into multiple rows

Inside a varchar2 column I have text values like :
aaaaaa. fgdfg.
bbbbbbbbbbbbbb ccccccccc
dddddd ddd dddddddddddd,
asdasdasdll
sssss
if i do select column from table where id=... i get the whole text in a single row, normally.
But i would like to get the result in multiple rows, 5 for the example above.
I have to use just one select statement, and the delimiters will be new line or carriage return (chr(10), chr(13) in oracle)
Thank you!
Like this, maybe (but it all depends on the version of oracle you are using):
WITH yourtable AS (SELECT REPLACE('aaaaaa. fgdfg.' ||chr(10)||
'bbbbbbbbbbbbbb ccccccccc ' ||chr(13)||
'dddddd ddd dddddddddddd,' ||chr(10)||
'asdasdasdll ' ||chr(13)||
'sssss '||chr(10),chr(13),chr(10)) AS astr FROM DUAL)
SELECT REGEXP_SUBSTR ( astr, '[^' ||chr(10)||']+', 1, LEVEL) data FROM yourtable
CONNECT BY LEVEL <= LENGTH(astr) - LENGTH(REPLACE(astr, chr(10))) + 1
see: Comma Separated values in Oracle
The answer by Kevin Burton contains a bug if your data contains empty lines.
The adaptation below, based on the solution invented here, works. Check that post for an explanation on the issue and the solution.
WITH yourtable AS (SELECT REPLACE('aaaaaa. fgdfg.' ||chr(10)||
'bbbbbbbbbbbbbb ccccccccc ' ||chr(13)||
chr(13)||
'dddddd ddd dddddddddddd,' ||chr(10)||
'asdasdasdll ' ||chr(13)||
'sssss '||chr(10),chr(13),chr(10)) AS astr FROM DUAL)
SELECT REGEXP_SUBSTR ( astr, '([^' ||chr(10)||']*)('||chr(10)||'|$)', 1, LEVEL, null, 1) data FROM yourtable
CONNECT BY LEVEL <= LENGTH(astr) - LENGTH(REPLACE(astr, chr(10))) + 1;
