Transact SQL :: Date Time Casting - Comparing Values And If Not Same Then Populating Record
Sep 9, 2015
I am trying to pull the records which are being affected i.e, comparing the values and if not same then populating the record.
I am using the below condition in where clause however i am getting runt time error as "Conversion failure when converting date and/or time from character string"
Condition in Where clause:
cast(isNull(tab1.Col1,'') as datetime) <> cast(isNull(tab2.col1,'') as datetime)
Note: Both col1 columns are of type nvarchar

SELECTIndustry,
100.0 * SUM(CASE when ceoischairman = 'yes' then 1 else 0 end) / COUNT(DISTINCT CompID) AS [YesPercent],
100.0 * SUM(CASE when ceoischairman = 'no' then 1 else 0 end) / COUNT(DISTINCT CompID) AS [NoPercent]
FROMTCompanies
GROUP BYIndustry
ORDER BYIndustry
This code above is working as I need it but I need to insert some additional functionality. Thanks
I need to add something like this:
IF YesPercent > NoPercent
UPDATE tableX SET CEOIsChairman='Yes' WHERE Industry='<the industry value being evaluated>'
Else If NoPercent > YesPercent
UPDATE tableX SET CEOIsChairman='No' WHERE Industry='<the industry value being evaluated>'
Else
UPDATE tableX SET CEOIsChairman='Equal' WHERE Industry='<the industry value being evaluated>'
End

I have a table called WorkItem. It models a chunk of work done duringa working day.It has two columns that I'm interested in:Start (smalldatetime) - the TIME the work block is begunDuration (int) - the duration in minutes of the work block.In another table called OvertimeRates I have information about ratemultipliers and a column that tells me the TIME that the ratemultiplier kicks in.e.g.OTRateBegins (smalldatetime)In terms of calculating whether a particular work block starts afterthe OTRateBegins, I could (I presume) do something like:If CONVERT(smalldatetime, Start, 108) > CONVERT(smalldatetime,OTRateBegins, 108)However, would I be better off using DATEPART functions to get the hourand minute parts of both the Start and OTRateBegins, and using theminstead? For some reason, (probably paranoia!), I am suspicious of theCONVERT function.Apologies for not posting DDL, but I felt that the situation didn'treally warrant it.ThanksEdward

Hi
Can anyone advise me as to how I can add the date and time to 2 columns in the sql server database for each record that is added. I'd prefer not to use the webform. Can sql server add the date automatically to the row?

how to write condition for self table year records, such 2012 name and acctno match with 2013 name and acctno then total, provided below,
create table #tab1 (MasterKey int, AcctNo varchar(12),name varchar(25), SumaofShares numeric, request_dat datetime )
--drop table #tab1
insert into #tab1 values (1000, 100,'Tom', 2500, '10/01/2012')
insert into #tab1 values (1001, 101,'Bat', 1550, '08/11/2012')
insert into #tab1 values (1002, 102,'Kit', 1600, '06/12/2012')
insert into #tab1 values (1003, 103,'Vat', 1750, '04/15/2012')
insert into #tab1 values (1010, 104,'Sim',200, '04/21/2013')
[code]....
i would like to get 4 columns output
how to get sumofshares (#tab1) and TotalOutStanding(#tab2) summ up with these values,
MasterKey (#tab1) and IssueKey (#tab2) are like primary key and foreign key
so the request is
need to calculate, sumofshares (#tab1) and TotalOutStanding(#tab2) as below
1)ShareBenefist = U and year( request_dat) in (2012 , 2103) and (Name for 2012 should match with 2013 name and 2012 Acctno should match with 2013 accounno) in (#tab1)
then '2012 and 2013 accts UN Veriverted'
2)ShareBenefist = V and year( request_dat) in (2012 , 2103) and (Name for 2012 should match with 2013 name and 2012 Acctno should match with 2013 accounno) in (#tab1)
then '2012 and 2013 accts Veriverted'
3)ShareBenefist = N and year( request_dat) in (2012 , 2103) and (Name for 2012 should match with 2013 name and 2012 Acctno should match with 2013 accounno) in (#tab1)
then '2012 and 2013 accts NONVERT'
4)year( request_dat) =2102 and Name and Acctno not match with 2013 account name and acctno (#tab1)
then '2012 last year accounts'
5)year( request_dat) = 2013 and Name and Acctno not match with 2013 account name and acctno (#tab1)
then '2012 This year accounts'
for ex 1) the below accounts in #tab1 has both 2012 and 2013 and acctno same in both years and name is same in both years so it is condired as
insert into #tab1 values (1012, 100,'Tom',800, '08/22/2013')
for ex 2)
insert into #tab1 values (1013, 101,'Bat',550, '09/15/2013')
for ex 4) 2012 records there is not match acctno and name in 2013 recods
insert into #tab1 values (1002, 102,'Kit', 1600, '06/12/2012')
for ex 5) 2013 records there is no match of name and acct no with 2012 records
insert into #tab1 values (1010, 104,'Sim',200, '04/21/2013')
insert into #tab1 values (1014, 100,'Pet',200, '02/21/2013')
insert into #tab1 values (1016, 110,'Sun',800, '03/22/2013')
insert into #tab1 values (1017, 111,'Bet',550, '12/15/2013')
Expected Results (just for format)
AcctTypeDescription,SumofShares, OtotalutStand
'2012 and 2013 accts UN Veriverted',2700,234
'2012 and 2013 accts Veriverted' ,2890,234
'2012 and 2013 accts NONVERT' ,4533,325

I have a situation where an agent has number of activities for a certain date range. If an agent has multiple activities within certain date range, I would like BALANCE BEFORE from the first activity and BALANCE AFTER from the last activity. Here is my current SQL query that returns the following data:
DECLARE @BeginDate Datetime
DECLARE @EndDate Datetime
Set @BeginDate = '05-1-2015'
Set @EndDate = '05-31-2015'
SELECT
a.AgentName,
R.BALANCEBEFORE,
[Code] ....
AGENTNAME BALANCE BEFORE BALANCE AFTER DATE
DOUGLAS 9738.75 9782.75 2015-05-11
DOUGLAS 9782.75 9804.75 2015-05-12
DOUGLAS 9804.75 9837.75 2015-05-13
In the sample data above, ideally I would like my query to return data as follow:
AGENTNAME BALANCE BEFORE BALANCE AFTER
DOUGLAS 9738.75 (from first activity) 9837.75 (from last activity)
Not sure how I can write sql query to accomplish this.

1999-01-02 01:00:00 5
...
1999-01-02 23:00:00 2
How can I use a query to get accumulate value for the day? the result should look like this:
Date Value Accumulated_Value
1999-01-01 00:00:00 10 10
1999-01-01 01:00:00 8 18

1999-01-02 01:00:00 5 14...
1999-01-02 23:00:00 2 16
The accumulated value should be based on every hour for the day and then repeat for the second day and so on.
What is the best way to do this? I am using SQL 2008

Biz talk server executes every query twice, first with FMT only to get metadata.If metadata changed, it will produce error.Now, i have query like:
SELECT col1, col2, col3 INTO #tmp FROM dbo.myTable
How SQL decide the type of column in #tmp? Does it create column of the same type as it is in dbo.myTable or its decision is based on result?For example, col1 is varchar(20), but col1 in #tmp will be varchar(200) or even nVarChar.Col2 is INT, but result is for example low number(like, 1,2,3,) - is it possible that col2 in #temp table will be smallint or tinyint even if col2 in myTable is INT.If that is true one way to overcome that will be to explicitly CAST all columns to proper data type. Is there any performance impact of casting: CAST(col1 as VARCHAR(20)) if col1 is already varchar(20) in dbo.myTable?

Hi.
Current development setup: Visual Studio 2005 (C# language), SQL Server 2005 Express Edition.
I am at this point changing some of my application. It stores a lot of information for times of trains. I decode a file which is text based and my times are stored in varchar(4) columns with the format "HHmm".
I am now at a stage where I need to add values to these times and perform a search based on two time values (a minimum time and maximum time).
I really need to be able to add another varchar(4) value to the times stored in my database (also varchar(4) - may look at this again in future). I have absolutely no interest in storing seconds, modifying the database to include the time colon, nor am I interested in the date portion of a time string, only the 4 digits representing the hours and minutes.
Can this be done easily in SQL server? For example:
varchar(4) of 0445 + varchar(4) of 0027 should result in the time 0512.
Similarly a varchar(4) of 2358 + varchar(4) of 0015 should result in the time 0013.
This has to be very quick to execute.
Thanks for any help you can offer!

I'm trying to translate this portion of VFP code into LINQ query:
select COUNT(ID) as conflicts
from dbo.max4sale where <<thisform.cWhere>>
AND Start_Time >= <<VFP2SQL(m.ltBegin + m.lnStartTime)>>
and Start_time <= <<VFP2SQL(m.ltEnd)>>
AND CONVERT(varchar(5),Start_Time,108) <= <<VFP2SQL(m.lcEndTime)>>
AND CONVERT(varchar(5),End_Time,108) >= <<VFP2SQL(m.lcStartTime)>>
<<m.lcDays>>
Here is my non-working attempt:
var startTime = new DateTime(1900, 1, 1, beginDateTime.Hour, beginDateTime.Minute, 0);
var endTime = new DateTime(1900, 1, 1, endDateTime.Hour, endDateTime.Minute, 0);
var daysOfWeek = dailyLimits.Where(dl => dl.Selected == true).Select(ds => ds.WeekDay).ToList();
if (daysOfWeek.Count() < 7) // not all days of the week selected
[Code] .......
First of all, I see a bug in my logic now as the first part of the query I need to do all the time and only the second part if the count < 7. But that's not my problem - I can not figure out how to make times comparison only using LINQ. Ideally I think I'd like to have cast(start_time as time) >= @p1 as a result to be executed by LINQ.
BTW, I am only getting the error in run-time that Parse can not be interpreted. So, I need to figure out another way of making LINQ recognize my intent of checking time portion of the date only.

Is there any way to convert a bind variable, which is a list of integer or string values, to nested table in MS SQL Server. I am looking for something like
CAST in Oracle, which converts a varray type column into a nested table. Do we have something like this in SQL Server.
in Oracle:
SELECT CAST(s.addresses AS address_book_t)
FROM states s
WHERE s.state_id = 111;
I have read about Table valued Parameter, but I am looking for another solution.

As a DBA, I am working on a project where an ETL process(SSIS) takes a long time to aggregate and process the raw data.
I figured out few things where the package selects the data from my biggest 200 GB unpartitioned table which has a datekey column but the package converts its each row to an integer value leading to massive scans and high CPU.
Example: the package passed two values 20140714 and 4 which means it wants to grab data from my biggest table which belongs between 20140714 04:00:00 and 20140714 05:00:00.
It leads to massive implicit conversions and I am trying to change this.
To minimize the number of changes, what I am trying to do is to convert 20140714 and 4 to a datetime format variable.
Select Convert(DATETIME, LEFT(20170714, 8)) which gives me a date value but I am stuck at appending time(HH:00:00) to it.

Hi All
My brain has truned to mush at the moment.
:(
I want to sort on a char(5) column with data in it that looks like
01/07
05/02
06/01
12/01
07/98
so it comes out in the human date order.
e.g
07/98
06/01
12/01
05/02
01/07

I am selecting older legacy data from an AS400 mainframe that we still use. I am fairly new to constructing T-SQL statements so I hope I am doing this correctly. There is a table from the AS400 that has been setup with a field for TMONTH, TDAY, and TYEAR. Instead of having one field for a date, for some reason years ago this was set up this way.
I now have this statement in my SELECT statement and it is not working:
WHERE (CAST(OWNR.TMONTH + '/' + OWNR.TDAY + '/' + OWNR.TYEAR AS DATETIME) >= @startdate)
I am not getting a syntax error, however I am getting "Error Converting data type varchar to numeric. These fields on the AS400 are set up as numeric fields.
What do I need to do differently? Should I use a CONVERT instead and if so, how would I structure that statement.
Thanks for the help

if I 'print' a MONEY value, or cast a MONEY variable to VARCHAR, it automatically rounds it to two decimal places. Maybe that's a built-in convenience, but I'd like to make it not do that.My workaround right now is to first cast my MONEY variabled to DECIMAL(30,4), and then cast the result to VARCHAR, but I'd like to avoid that step if possible.Consider the following
query:DECLARE @UnitCost MONEY SET @UnitCost = .0167 SELECT @UnitCost,
CAST(@UnitCost AS VARCHAR(30)),
CAST(CAST(@UnitCost AS DECIMAL(30, 4)) AS VARCHAR(30)) -
- Results in: 0.0167, 0.02, 0.0167

Hello all,
I am trying to think my way through a solution which I believe others have probably come across... I am trying to implement a matching routine wherein I need to match an address against a high value and a low value (or, for that matter an input date vs. a start and end date) to return the desired row ... i.e. if I were to use a straight vb program I would just use the following lookup:
"SELECT DISTINCT fire_id, police_ID, fire_opt_in_out, police_opt_in_out FROM ipt_tbl " & _
" WHERE zip_code = @zip_code AND addr_prim_lo <= @street_number AND addr_prim_hi >= @street_number " & _
" AND addr_prim_oe = @addr_prim_oe AND street_pre = @street_pre AND street_name = @street_name " & _
" AND street_suff = @street_suff AND street_post = @street_post " & _
" AND (expiry_date = '' OR expiry_date = '00000000' OR expiry_date > @expiry_date)" & _
" GROUP BY fire_ID, police_ID, fire_opt_in_out, police_opt_in_out"
My question, then, is how would you perform this type of query using a lookup / merge join or script? I have not found a way to implement a way to set the input columns? I can set the straight matches without a problem, i.e. lookup zip code = input zip code, but can't think of the correct way to set comparisons, i.e. lookup value 1 <= input value AND lookup value 2 >= input value
Any suggestions?
thanks for your time...

I have a Foreach loop container that I'm using to loop through a directory and copy files to a new directory. The file name contains the date and I need to compare the value to the current date to determine if the file should moved. I'm having a problem converting the string to a date.
I have a FileName variable of type string that is in this form: 200710221200_FileName_7001.log
I have a FileDate variable of type datetime that I'm trying to use the following expression on:
(DT_DBDATE)(SUBSTRING(@[User::FileName] , 1,4) +"-"+ SUBSTRING(@[User::FileName] , 5,2) +"-"+SUBSTRING( @[User::FileName] , 7,2))
Which is giving me the following error:
The expression "(DT_DBDATE)(SUBSTRING(@[User::FileName] , 1,4) +"-"+ SUBSTRING(@[User::FileName] , 5,2) +"-"+SUBSTRING( @[User::FileName] , 7,2))" has a result type of "DT_DBDATE", which cannot be converted to a supported type.
From the help files, it appears to me that the DT_DBDATE cast uses the form of yyyy-mm-dd. I'm not sure what I'm doing wrong. Any help is greatly appreciated.
Thanks!

I've imported a CSV file into a table in SQL Server 2012. It's a large file, 140,000+ rows, so I couldn't covert it to Excel first to preserve the date format due to Excel's row limit. In the CSV file, there were 3 column with date data in "31-Aug-09" format, and the import automatically transformed these in "31AUG09" format (varchar(50)) in SQL Server. Now I need to convert these 3 columns from varchar to datetime so I could work with them in date format.
I've tried several things,e.g,
select
convert(datetime,
right(admdate,4)+left(admdate,2)+substring(admdate,3,3))
or
select
convert(datetime,
substring(admdate,6,4)+substring(admdate,1,2)+substring(admdate,3,3))
but keep getting the same error message (Msg 241) "Conversion failed when converting date and/or time from character string".
