How To Get The First Occurrence Of A Record From A Table?
May 21, 2007
I have the following query:
SELECT Notifications.[TimeStamp])
FROM dbo.vwGrantsMaster LEFT OUTER JOIN
dbo.CoFundNotifications ON dbo.vwGrantsMaster.GrantFMBId = dbo.CoFundNotifications.GrantsFMBId
It is returning multiple records from Notifications table since it allows multiple entries under a single GrantFMBId. For example for a single GrantFMBId there can be multiple TimeStamp. When retrieved all are appearing even distinct key word is used.
What I am looking is that to get only the first occurrence of a record for a GrantFMBId from Notifications table.
Any help?
Thank you in advance.

Here is a CTE query
With mstrTable(ItemNo, Sales)
as (
Query1
Union All
Query2
)
Select Row_Number () Over(Partition by ItemNo order by ItemNo)as RowNo, ItemNo, Sales
From mstrTable
order by ItemNo
The results from Query1 and Query2 overlap sometimes.
The result set looks like:
1 Item1 10000
2 Item1 10000
1 Item2 20000
1 Item3 30000
I only want the first occurrence of each item. The desired result set is:
1 Item1 10000
1 Item2 20000
1 Item3 30000
I am not able to add a "Where RowNo = 1" to the query. SQL returns an "invalid field name".How would I obtain a record set that returns just the first occurrence of the ItemNo field?

Hi
I have a table with a user column and other columns. User column id the primary key.
I want to create a copy of the record where the user="user1" and insert that copy in the same table in a new created record. But I want the new record to have a value of "user2" in the user column instead of "user1" since it's a primary key
Thanks.

Hi All,I have a table in SQL Server 2000 that contains several million memberids. Some of these member ids are duplicated in the table, and eachrecord is tagged with a 1 or a 2 in [recsrc] to indicate where theycame from.I want to remove all member ids records from the table that have arecsrc of 1 where the same member id also exists in the table with arecsrc of 2.So, if the member id has a recsrc of 1, and no other record exists inthe table with the same member id and a recsrc of 2, I want it leftuntouched.So, in a theortetical dataset of member id and recsrc:0001, 10002, 20001, 20003, 10004, 2I am looking to only delete the first record, because it has a recsrcof 1 and there is another record in the table with the same member idand a recsrc of 2.I'd very much appreciate it if someone could help me achieve this!Much warmth,Murray

Could anybody help me with the following scenario:
Table 1 Table2
ID,Date1 ID, Date2
I would like to link the two tables and receive all records from table2 joined on ID and the record from table1 that has the most recent date.
Example:
Table1 data Table2 Data
ID Date1 ID Date2
31 1/1/2008 31 1/5/2008
34 1/4/3008 31 4/1/2008
31 3/2/2008
The first record in table2 would only link to the first record in table1
The second record in table2 would only link to the third record in table1
Any help would be greatly appreciated.
Thanks

I am trying to update a record in a table based off of criteria of another record in the table.
So suppose I have 2 records
ID owner type

So, I want to update the type field to "collections" only if the previous record for the same record is "past due". Any ideas?

I'm inserting from TempAccrual to VacationAccrual . It works nicely, however if I run this script again it will insert the same values again in VacationAccrual. How do I block that? IF there is a small change in one of the column in TempAccrual then allow insert. Here is my query
INSERT INTO vacationaccrual
(empno,
accrued_vacation,
accrued_sick_effective_date,
accrued_sick,
import_date)

2 | 7.00 | Towel
3 | 5.00 | Flower
3 | 6.00 | Candy
Should only select:

This one shouldn't be too hard to do, just can't seem to figure it out.
I have two tables
tNames which contains 'ID' and 'Name'
tLocations which contains 'ID' and 'Location'
each ID may be associated with many Locations
I want to run a query to display these results:
[ID, Name, Location]
but only to return the first Location associated with that ID (or the max, min, I don't really care as long as it's only one result)
right now I have
Code:
SELECT tNames.ID, tNames.Name, tLocation.Location
FROM tNames INNER JOIN tLocations
ON tNames.ID = tLocations.ID
but this returns a new row for each different Location of the same ID
Thanks.

In the table you can create below, each set of order number records should contain one record with the OrderNoIndicator field set to 1. i.e. OrderNo 7032357. Is there a way of finding(without using the count function) sets of records that don't contain an OrderNoIndicator set to 1 i.e. OrderNo 7088650 all the OrderNoIndicator fields are set to 2...
use LEIS
If OBJECT_ID ('dbo.temp') IS NOT NULL
DROP TABLE dbo.temp
GO
CREATE TABLE dbo.temp
( OrderNo bigint not null,
OrderNoindicator tinyint not null

Hi... I was hoping if someone could share me some thoughts with the issue that I am having at the moment.
Problem: When I run the package in my local machine and update local SS DB/table - new records writes OK in the table. BUT when I changed my destination meaning write record into another physical SS DB/table there is no INSERT data occurs. AND SO when I move/copy over that same package into another server (e.g. server that do not write record earlier) and run it locally IT WORKS fine too.
What I am trying to do is very simple - Add new records in a SS table using SSIS . I only care for new rows and not even changed rows.
Here is my logic -
1. Create Ole DB source to RemoteSERVER - using SELECT stmt
2. I have LoopUp component that will look for NEW records - Directs all rows that don't find match and redirect rows (error output).
3. Since I don't care for any rows that is matched in my lookup - I do nothing or I trash the rows
4. I send the error rows (NEW rows) into OleDB destination
RESULTS when I run the package locally and destination table is also local - WORKS FINE;
But when I run the package locally and destination table is in another Sserver (remote) - now rows is written.
The package is run thru BIDS manually so there is no sucurity restrictions attached to it.
I am not sure what I am missing. And I do not see error in my package either. It is not failing.
Thanks in advance!

I would like to find out how to capture record count for a table in oracle using SSIS and then writing that value in a SQL Server table.
I understand that I can use a variable to accomplish this task. Well first issue I run into is that what import statement do I need to use in the design script section of Script Task. I see that in many examples following statement is used for SQL Server databases:
Imports System.Data.SqlClient
Which Import statement I need to use to for Oracle database. I am using a OLE DB Connection.
any idea?
thanks

I have a table in different databases with the same name. My goal is to compare the two tables, and insert a record into the second table where there is not a match in the first table. So far, my query looks like the following:
SELECT [metal] FROM [ProductionDatabase].[dbo].[Metalurgy]
EXCEPT
SELECT [metal] FROM [TestDatabase].[dbo].[Metalurgy]
This gives me a list of records from [Production].[dbo].[Metalurgy] which do not reside in [TestDatabase].[dbo].[Metalurgy]. Now, I need to use that list to insert missing records into [TestDatabase].[dbo].[Metalurgy]. How can I modify the above code to INSERT the missing records?

Have a need to scan a large table to see if a set of criteria have ever been met.
If/when the scan hits its first record meeting the criteria, the scan can be abandoned.
Is there some syntax/option that accomplishes this?
Right now, I am doing a SELECT with criteria against the table and the @@ROWCOUNT gives me a zero, or non-zero value.
But that methodology means that the SELECT has to execute against the entirety of the table.
I'd like to abandon the SELECT as soon as it detects a first record meeting the criteria.
