I am checking to see if the source record is available in the target table using a lookup transformation and if not found i have to insert this record.
I have connected the error flow of the lookup transformation to the target. I am acheiving expected results, but is this the best practise? I have not connected to the green arrow to any task.
I've decided to post this as a sticky given the frequency this question is asked.
For those of you wishing to build a package that determines if a source row exists in the destination and if so update it else insert it, this link is for you.

I've got two tables, one containing a list of company names(approx 10,000 records), the other containing a list of company employees (approx 30,000 records) joined by the CompanyID column.
I have a third table (approx 700 records) containing new employees to be added to the employee table. Each record in this table has the employees details plus the name of their company.
I want to write a query that will check each row in the third table to see if
a) the employee exists in the Employees table
b) the company exists in the Companies table and
c) the employee is listed under the correct company
The query should also handle any combination of the above. So if the company doesn't exist but the employee does, create the company on the companies table and update the appropriate record on the employees table with the new CompanyID etc. etc.
Oh, forgot to mention. The company names in the third table won't be exactly the same as the ones in the Company table so will need to use CharIndex.
Anybody got any ideas?
I'm trying to check which price grids are in use using the price grid_id, and seeing whether this grid_id exists in another query that checks all active contracts. If the grid_id is present (active) I want to return 'Yes', if not I want it to return 'No'.
There are 385 price grids, but my query is only returning the 315 that are active, and ignoring any that are not used. My code is below, how I can see all the records whether Yes or No:
Select distinct
pg.grid_id [Price Grid],
pg.grid_name [Grid Name],
case when exists
(Select
c.grid_id from
customers c
inner join deltickhdr dh on dh.acct = c.custnum and dh.stage <5
where
c.type = 'C' and
dh.dticket is not null) then 'Yes' else 'No' end [Active]
From gridhdr pg inner join customers c on c.grid_id = pg.grid_id
Order by pg.grid_id

Hello folks,
I am new to msSQL and ASP, I need some help writing an SQL statement that will first check to see if a combination or record exists, if none found thant it will add it. I am working a section of a site that adds favorites to the database. Each user can have more that one favorite hence it has to check for that unique combination of the fields, UserID and FavID
My Code:
Dim objConnection, objRecordset, strSQL
Dim strFavID, strUserID
strFavID = request.Form("favid")
strUserID = request.Form("userid")
Set objConnection = Server.CreateObject("ADODB.Connection")
Set objRecordset = Server.CreateObject("ADODB.Recordset")
objConnection.Open Application("ConnectionString")
strSQL = "INSERT INTO FAV (UserID,FavID) (SELECT DISTINCT " & strUserID & " AS UserID " & _
strFavID & " AS FavID" & " FROM FAV)" & _
" WHERE " & strUserID & " & " & strFavID & " NOT IN (SELECT UserID, FavID FROM FAV)"
response.Write(strSQL)
'response.End()
If strFavID <> "" Then
On Error Resume Next
objConnection.Execute(strSQL)
objConnection.Close
Set objConnection = Nothing
End If
This code is giving me a syntax error, how do I write the correct statement. I am using MS Access 2k

How can I check for file exitence in a specified folder using TSQL?
I can think of a couple of ways to do this so any feedback would be appreciated.
Load the contents of a folder in to a temporay table and check the table for file name. I can do this with something like:
insert into myFiles
exec master..xp_cmdshell 'dir /B /OND filePath*.txt'
Or maybe use OLE Automation Sproc? But I am not sure which method I should use.
Please advise.
I would like to be able to check if a certain entry exists in a SQL table. Ideally, the output would be a boolean so I can use it in an IF statement which would tell it what to do depending on whether or not the entry exists. Thanks for anyone that helps. :)

I'm trying to put scripts to create our stored procedures under version control.
However I don't want these scripts to be run if the stored procedure already exists (we'll be using update scripts to alter existing stored procedure I think).
Anyway I tried :
Code:
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
/****** Object: Stored Procedure dbo.getEnglandHotelsByATOPResort Script Date: 26/10/2005 10:40:01 ******/
if NOT EXISTS (SELECT object_id('procedureName','p'))
CREATE PROCEDURE [dbo].[procedureName]
@location char(2)
AS
...Procedure...
GO
SET QUOTED_IDENTIFIER OFF
GO
SET ANSI_NULLS ON
GO
I know that the if NOT EXISTS ... part works as doing the following returns the expected result :
Code:
IF NOT EXISTS (SELECT object_id('procedureName','p'))
SELECT 'FALSE'
ELSE
SELECT 'TRUE'
However when trying to do this before the CREATE PROCEDURE I get :
Server: Msg 156, Level 15, State 1, Line 4
Incorrect syntax near the keyword 'PROCEDURE'.
Server: Msg 137, Level 15, State 1, Line 12
Must declare the variable '@location'.
Any ideas how to do this?

How to handle the scenario if a employee applies leave between the range 23/01/2015 to 27/01/2015, since 26/01/2015 is a holiday in between. how the data can still be inserted excluding 26/01/2015

I have 1+ CSV files (using a foreach loop) which I'm doing a lot of transform work on and then inserting into a SQL database table.
Each CSV file usually contains about 2 days worth of data (contains date stamps) - somewhere in the region of 60k records per day.
The destination table currently contains 3 million+ rows and will get bigger.
I need to make sure that before inserting into the destination table, the data doesn't already exist.
I've read the following article: http://www.sqlis.com/311.aspx
While the lookup method works, it takes ages and eats up memory as it caches the 3m+ records before running for each CSV. Obviously this will only get worse as the table grows in size.
To make things a little more efficient what I'd like to do, is first derive the dates I'm dealing with in the current file - essentially storing the max(date) and min(date) in variables. Then in the lookup SQL use those vars, to reduce the amount of data that needs to be brought into the transformation to check against before inserting into the destination table.
Lookup SQL eg. SELECT * FROM MyTable WHERE Date BETWEEN varMinDate AND varMaxDate.
Ideally I'd use an aggregate transformation and then use the subsequent output from that either in the lookup query or store the output in vars, but I don't think you can do that and I get the feeling I'm approaching this with the wrong mindset.
Any thoughts would be great!

View 1 Replies View RelatedHello,
I have an SSIS package that affects data in fourteen tables. This SSIS packge is supposed to insert, update, delete and apply various business rules to the data in the new database tabes in the same way that it occurs in the DTS package that affects the old tables in the former database.
After both the DTS packge and SSIS packages are run, the data in the fourteen tables from both databases need to mirror each other. I figure this is the best way that I can know that the new SSIS package is working correctly.
Is there something I can do in an SSIS package that can compare all of the tables between the two databases, record for record then (maybe as error output) produce output in the case where a mistmatch was detected between two given tables? Would a lookup transformation be helpful for this kind or thing, or should I think about doing it some other way?
The old database is on SQL Server 2000, and the new one on SQL Server 2005 64 bit. I've run into problems creating a linked server between the two to where I could just run queries to do this kind of check.
Any ideas?
Thank you for your help!

Hello,
I have two tables with the same field layout, and they both have the same field as the Primary Key. They just contain different data. I would like to know if a record exists in one, or both, tables.
The tables are InvTemp1 and SalesTemp1. The key for both is stock_number.
Here is the command so far:
SELECT COUNT(*)
FROM InvTemp1 INNER JOIN SalesTemp1 ON InvTemp1.Stock_number = SalesTemp1.Stock_number
WHERE (InvTemp1.Stock_number = '101053')

Hey gang,
I've got a query and I'm really not sure how to get what I need. I've got a unix datasource that I've setup a linked server for on my SQL database so I'm using Select * From OpenQuery(DataSource, 'Query')
I am able to select all of the records from the first two tables that I need. The problem I'm having is the last step. I need a field in the select statement that is going to be a simple yes or no based off of if a customer number is present in a different table. The table that I need to look into can have up to 99 instances of the customer number. It's a "Note" table that stores a string, the customer number and the sequence number of the note. Obviously I don't want to do a straight join and query because I don't want to get 99 duplicates records in the query I'm already pulling.
Here's my current Query this works fine:
Select *From OpenQuery(UnixData, 'Select CPAREC.CustomerNo, CPBASC_All.CustorCompName, CPAREC.DateAdded, CPAREC.Terms, CPAREC.CreditLimit, CPAREC.PowerNum
From CPAREC Inner Join CPBASC_All on CPAREC.CustomerNo = CPBASC_All.CustomerNo
Where DateAdded >= #12/01/07# and DateAdded <= #12/31/07#')
What I need to add is one more column to the results of this query that will let me know if the Customer number is found in a "Notes" table. This table has 3 fields CustomerNo, SequenceNo, Note.
I don't want to join and select on customer number as the customer number maybe repeated as much as 99 times in the Notes table. I just need to know if a single instance of the customer number was found in that table so I can set a column in my select statement as NotesExist (Yes or No)
Any advice would be greatly appreciated.
What I want to do is return a row of data when my query doesn't return a record. I have two tables:
CREATE TABLE dbo.abc(
SeqNo smallint NULL,
Payment decimal(10, 2) NULL
) ON PRIMARY
[Code] ....
So when I run the following query:
SELECT 'abc' + '-' + CAST(SeqNo AS VARCHAR) + '-' + CAST(Payment AS VARCHAR) FROM abc WHERE SeqNo = 1
UNION
SELECT 'def' + '-' + CAST(SeqNo AS VARCHAR) + '-' + CAST(Payment AS VARCHAR) FROM def WHERE SeqNo = 1
abc-1-200.00
abc-1-500.00
As you can see since 1 doesn't exists in table 'def' nothing is returned as expected. However, if a row isn't returned I want to be able to enter my own row such as
abc-1-200.00
abc-1-500.00
def-0-0.00
I have a situation where our stored procedure inserts records from table_1 to table_2 when they don't already exist (uses the EXIST statement) on that table. If table_1 contains multiple records that are the same, it appears after the 1st record has been inserted, it does not recognize it as being there when it checks the existence when attempting to insert record 2.
Here's an example of the script:
insert into table_2 (col1,col2,col3)
select col1,col2,col3
from table_1 t1
where not exists (select '1'
from table_2 t2
where t1.col1 = t2.col1
and t1.col2 = t2.col2
and t1.col3 = t2.col3)
Data from Table_1 -- Assume that table_2 does not contain these records
col1 col2 col3
AA 11 A1
AA 11 A1
BB 22 B2
All 3 records would be inserted to table_2 in this example.
