Unique Timestamp

Nov 6, 2007

Hi,

i need to create a sql statement to get the latest timestamp for a user and am struggling

my table once it has been joined has

employee id door permiter door time
1 1 yes 12/12/2002 10:00
1 1 yes 13/12/2002 10:00
1 1 yes 14/12/2002 10:00

3 1 yes 12/12/2002 10:00
4 1 yes 12/12/2002 10:00


So what i would like returned from this would be:
employee id door permiter door time
1 1 yes 14/12/2002 10:00

Converting DB2 Timestamp Data To SQL Server 2005 - Problems With Unique Index

May 24, 2007

I am attempting to move a timestamp data column from DB2 to SQL Server 2005. Normally not a big deal but the column is part of unique index.



The DB2 timestamp has seconds of ss.ssssss but SQL Server only has ss.sss.



Most all the times entered into this column are a from an automated process so they are really close together timewise.



Here is what I have come up with so far:

1. Fast Load OLEDB with a batch of 10,000 records at a time

2. On the fail of the batch redirect rows to a regular table load OLEDB insert task

3. On the fail of the single insert redirect rows to script that ups the seconds one tick.

4. Attempt one last insert of the modified rows

5. If fail, then store the record off to a delimited text file



I am hoping to get the number of records that wind up in the delimited text file to be a very small number and not in the 1,000+.



Any help would be appreciated.

Integration Services :: Load Incremental Data Into Fact Table When Source Table Not Have Timestamp And Unique Key

Sep 24, 2015

I have a transaction table having about 40 crore rows in source. It don't have timestamp and unique key columns. It have only Bill_month and Bill_Year columns. Actually for loading this table into staging I have added a new datetime column by adding default bill_date as 01. Then

* First we delete last 3 month data from staging tables.
* Get last 3 months data from source table.
* Load that 3 months data from source to staging table. 

We do this because we only get update for last three months data. Now I have to include this transaction table as Fact table in DW. What will be the best practice for loading the fact table by picking data form staging table. Also we have to look up with dimensions for Foreign Keys. 

* Should I implement the same method of deleting last 3 months records and loading them again.

Error While Converting Oracle Timestamp To Sql Server Timestamp (datetime) - Invalid Date Format

Jun 19, 2007

I am populating oracle source in Sql Server Destination. after few rows it fails it displays this error:

[OLE DB Destination [16]] Error: SSIS Error Code DTS_E_OLEDBERROR. An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft OLE DB Provider for SQL Server" Hresult: 0x80004005 Description:
"Invalid date format".



I used this script component using the following code in between the adapters, However after 9,500 rows it failed again giving the same above error:








To convert Oracle timestamp to Sql Server timestamp

If Row.CALCULATEDETADATECUST_IsNull = False Then

If IsDate(DateSerial(Row.CALCULATEDETADATECUST.Year, Row.CALCULATEDETADATECUST.Month, Row.CALCULATEDETADATECUST.Day)) Then

dt = Row.CALCULATEDETADATECUST

Row.CALCULATEDETADATECUSTD = dt

End If

End If



I don't know if my code is right . Please inform, how i can achieve this.

Get Row Timestamp With No Timestamp Column

Jul 10, 2007

For starters, please feel free to move this if it is in the wrong forum.



The issue I have is this. I have been asked to delete all information from a table that was inserted before May 12 this year. The issue is that when the DB was created, whoever designedd it neglected to add a timestamp column for the user data table (the one I need to purge). Does SQL, by default, happen to store insert times? Would it be something that might hide ina log file somewhere?

What Is The Difference Between A UNIQUE INDEX And A UNIQUE CONSTRAINT?

Sep 22, 2004

A UNIQUE INDEX must inherently impose a unique constraint and a UNIQUE CONSTRAINT is most likely implemented via a UNIQUE INDEX. So what is the difference? When you create in Enterprise Manager you must select one or the other.

Unique Constraint And Unique Index, What's The Difference?

Jun 24, 2006

What's the difference in the effect of the followings:
CREATE UNIQUE NONCLUSTERED INDEX
and
ALTER TABLE dbo.titles ADD CONSTRAINT
titleind UNIQUE NONCLUSTERED

I found there're two settings in Indexs/Keys dialog box of the management studio, Is Unique, and Type. The DDL statements above are generated by setting Is Unique to yes plus Type to Index, and just Type to Unique Key, respectively. What's the difference between them?

Unique Index Vs Unique Constraint

Mar 7, 2001

Hi everyone,
I need urgent help to resolve this issue...
As far as the performance goes which one is better..
Unique Index(col1, col2) OR Unique constraint(col1, col2) ?
Unique constraint automatically adds a unique index
and unique index takes care of uniqueness then whats the use of unique constraint ?

Which one do one use ?

thanks

Unique Constraint Vs Unique Index

BOL says a unique constraint is preferred over a unique index. It also states that a unique constraint creates a unique index. What then is the difference between the two, and why is a constraint preferred over the index?

How To Select Unique Row When Entire Row Not Unique?

Mar 12, 2008

I am having a problem trying to figure out the best way to get the results I need. I have a table of part numbers that is joined with a table of notes. The table of notes is specific to the part number and user. A row in the notes table is only created if the user has entered notes on that part number. I need to create a search that grabs all matches on a keyword and returns the records. The problem is that it currently returns a row from the parts table with no notes and a separate row with the notes included if they had created an entry. It seems like this should be easy but it eludes me today.
Here is the code



Code Snippet
create procedure SearchPartKeyword
(
@Keyword varchar(250) = null,
@Universal_Id varchar(10) = null
)
as
select p.PartNumber, p.Description, p.ServiceOrderable, n.MyNotes, p.LargestAssembly, p.DMM,
p.Legacy, p.Folder, p.Printer
from Parts p inner join notes n on p.PartNumber = n.Identifier
where n.Universal_ID = @Universal_ID and p.Description like @Keyword
union
select p.PartNumber, p.Description, p.ServiceOrderable, '' as MyNotes, p.LargestAssembly,
p.DMM, p.Legacy, p.Folder, p.Printer
from Parts p
where p.Description like @Keyword





and the results:
PartNo Description SO Notes LA DMM Legacy Folder Printer
de90008 MAIN BOARD 1 DGF1 114688 0 0 0
de90008 MAIN BOARD 1 I love this part Really I do DGF1 114688 0 0 0

This could return multiple part numbers and If they have entered notes I want the row with the notes

Thank You

A Unique Unique Constraint

May 1, 2008

Here is the table I created:

create table Test (
[recId] [int] identity(1, 1) not null,
[code] [varchar](50) not null,
[prime] [bit] not null constraint [DF_Test_prime] default (cast(0 as bit)),
constraint [PK_Test] primary key clustered
(
[recId]
) with fillfactor = 90 on [primary]
) on [primary]
go

insert into Test (code, prime) values ('AVA', cast(1 as bit))
insert into Test (code, prime) values ('BUS', cast(1 as bit))
insert into Test (code, prime) values ('BUS', cast(0 as bit))
insert into Test (code, prime) values ('BUS', cast(0 as bit))
insert into Test (code, prime) values ('CAR', cast(1 as bit))
insert into Test (code, prime) values ('CAR', cast(0 as bit))
insert into Test (code, prime) values ('RLW', cast(1 as bit))
insert into Test (code, prime) values ('RLW', cast(0 as bit))
insert into Test (code, prime) values ('RLW', cast(0 as bit))

select *
from Test

I need to create a constraint on this table that will not allow me to have two rows that are prime for the same code. So the following insert statement should fail:

-- This should fail
insert into Test (code, prime) values ('RLW', cast(1 as bit))


Thanks for you help!

Timestamp

Nov 29, 2007

Hi there,



When inserting into a table with a timestamp column without explicitly setting the column_list you get the following.

ie.



insert into Table_A

select *

from Table_B



Cannot insert a non-null value into a timestamp column. Use INSERT with a column list or with a default of NULL for the timestamp column.



I was wondering if there's a way to overcome this without specifying the column list?



Thanks.
