Check Data Before Insert

Aug 15, 2007

I need help thinking about this problem :-)

I have an SSIS pkg that automatically downloads financial extracts from an ftp site. Once the files are downloaded, I load the extract to a table. The table is first deleted before the insert, so that each time the table has "fresh" data (whatever was in the extract for that day).

Once the extract data is in the table, I load the data into yet another table that combines data from many tables. Simple enough.

Problem is, sometimes when I download the extract, it hasn't been updated yet, so I'm downloading an OLD extract. This old data then gets loaded into the first table. That's ok, because it doesn't really hurt anything. I can always delete the table and reload it if necessary.

The problem occurs when the old data goes from this table into the OTHER table. We don't want old data in this other table!

I need a way to check that I'm not loading the same data 2 days in a row into the OTHER table.

I realize that I might be able to solve this problem without using SSIS, but the solutions I've come up with so far aren't 100% satisfactory. I can use a query to check dates and that sort of thing, but it isn't foolproof, and would create problems if I need to manually force the process though, that is, if I need to override the date logic.

Anyways, I'm wondering if there's an SSIS approach to this problem... I can't rely on timestamps on the data files either. They're not accurate.

This is has been very perplexing to me.

Thanks

Check Before INSERT

Aug 6, 2007

I have a pretty standard form that inserts users name, office, and team. It generates a random 10 digit ID for them. How would i got about checking the table to make sure that ID doesn't exist?
Here's my insert code.
        string strConnection = ConfigurationManager.ConnectionStrings["TimeAccountingConnectionString"].ConnectionString;        SqlConnection myConnection = new SqlConnection(strConnection);
        string usercode = GenPassWithCap(9);
        String insertCmd = "INSERT into users (ID, firstname, lastname, office, team) values (@id, @firstname, @lastname, @office, @team)";        SqlCommand myCommand = new SqlCommand(insertCmd, myConnection);
        myCommand.Parameters.Add(new SqlParameter("@id", SqlDbType.VarChar, 10));        myCommand.Parameters["@id"].Value = usercode;
        myCommand.Parameters.Add(new SqlParameter("@firstname", SqlDbType.VarChar, 50));        myCommand.Parameters["@firstname"].Value = txtFirstName.Text;
        myCommand.Parameters.Add(new SqlParameter("@lastname", SqlDbType.VarChar, 50));        myCommand.Parameters["@lastname"].Value = txtLastName.Text;
        myCommand.Parameters.Add(new SqlParameter("@office", SqlDbType.VarChar, 75));        myCommand.Parameters["@office"].Value = dwnOffice.SelectedValue;
        myCommand.Parameters.Add(new SqlParameter("@team", SqlDbType.VarChar, 20));        myCommand.Parameters["@team"].Value = dwnTeam.SelectedValue;
        myCommand.Connection.Open();
            myCommand.ExecuteNonQuery();
 Do I run a completey different select command before hand and try to match that field?

Check Box Insert Question

Dec 10, 2003

I have 3 tables - Data, Facility and FacilityKey

The FacilityKey table will hold the Data ID and Facility ID based on a series of check boxes on a form.

My question is what is the best way to do the insert into the FacilityKey table from the form? If 5 facilities are checked I don't want to do 5 separate calls to the database for inserts, but I'm a bit confused on what the best method would be.

Thank you!

Check For Column && Insert

Jan 7, 2007

Can you tell me if this is possible? (and how to do it!!)

The application is VS2005, with sql database.

I want to check if a specific column exists in a specific table in the database and if not then add it, all via my application.

I'm happy knowing how to connect to the database & pass sql commands (as I'm doing that anyway to set off backups), but not the actual queries I'd need.

Query Question - Check Before Insert

Dec 1, 2003

I have a table, emailaddresses with an emailaddress field.

before i do an insert from a stored proc, i want to check if the emailaddress is already in the database.

pseudo-code:

if emailaddresssparameter is IN emailaddress then
do not insert
else
insert into table
end

i've got the insert statement and the stored proc, but how do i write the check to see if it's already there? I mean i could do a select * from emailaddress wehre emailaddress=emailaddressparam

but how to i test it? if the count=1 then skip?

here's my proc now:

ALTER PROCEDURE dbo.AddOneEmailAddress

(
@emailAddress varchar(255),
@emailID int=0 OUTPUT
)

AS
/* SET NOCOUNT ON */
insert into EmailAddresses
(email_address)
values
(@emailAddress)
set @emailID=@@identity

RETURN @@identity

SSIS: Check -&&>Update -&&>Insert

Sep 7, 2007

I have two tables from two different Databases

DB1.dbo.Table1 and DB2.dbo.Table2

eX:

Table 1
KEY LName FName Updated
1 GYM ABC Y
1 TIM ABC N
1 PIN ABC N
2 QWE SAD Y
......
....


Table 2
KEY LName FName Updated
1 JIM ABC Y
2 QWE SAM Y

....
....


1) Table 1 and Table 2 are of same structure.
2) In table2, as in above example, few changes have beeen done for KEY1 AND Update =Y, Similarly KEY= 2 AND UPDATED=Y, like for KEY= 1 LName was changed to JIM instead of GYM and for KEY= 2 FName has been changed to SAM instead of SAD.

3) Now I want to do this in SSIS where
a) Its going to process rows of Table2 and check in table1 according to KEY and UPDATE=Y and update the Table1 with Updated = N and Insert that particulra process row of Table2 into Table1

and hence Resultant of Table1 must be like this

Table 1
KEY LName FName Updated
1 GYM ABC N
1 TIM ABC N
1 PIN ABC N
1 JIM ABC Y

2 QWE SAD N
2 QWE SAM Y
......
....

Can somebody help me how to do this in SSIS. Thnaks a lot in advance

How To Check If An Insert Stored Proc Succeeded

Mar 5, 2007

Hi,
How would I check if an insert via stored proc succeeded? Here's the proc I'm using:set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
-- =============================================
-- Author:<Author,,Name>
-- Create date: <Create Date,,>
-- Description:<Description,,>
-- =============================================
ALTER PROCEDURE [dbo].[showtube_addNewSUser]
-- Add the parameters for the stored procedure here
@UserId uniqueidentifier,
@FirstName nvarchar(32),
@LastName nvarchar(32),
@DescShort nvarchar(256),
@DescLong ntext,
@ClanID uniqueidentifier
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;

-- Insert statements for procedure here
Insert into dbo.Users (UserId, FirstName, LastName, DescShort, DescLong, ClanID)
values (@UserId, @FirstName, @LastName, @DescShort, @DescLong, @ClanID);
END


 
 
I tried adding a Return @@RowCount before the END statement, but it always seems to return -1. Could someone tell me what I'm doing wrong? Thanks.

SQL Server 2008 :: Insert Data Into Table Variable But Need To Insert 1 Or 2 Rows Depending On Data

Feb 26, 2015

I am writing a query to return some production data. Basically i need to insert either 1 or 2 rows into a Table variable based on a decision as to does the production part make 1 or 2 items ( The Raw data does not allow for this it comes from a look up in my database)

I can retrieve all the source data i need easily but when i come to insert it into the table variable i need to insert 1 record if its a single part or 2 records if its a twin part. I know could use a cursor but im sure there has to be an easier way !

Below is the code i have at the moment

declare @startdate as datetime
declare @enddate as datetime
declare @Line as Integer
DECLARE @count INT

set @startdate = '2015-01-01'
set @enddate = '2015-01-31'

[Code] .....

Create Trigger To Check Values At Insert/update

Feb 10, 2004

I have never used triggers before and I have tried to solve one problem. If I have the column "currency" in a table and want to make sure that the entered value i valid in relation to another table that contains valid currency formats, I did it like this:

---------------------------------
CREATE TRIGGER [trigger_checkCurrency] ON [dbo].[Client]
FOR INSERT, UPDATE
AS
declare @currency as char(50)
declare @country as char(50)

declare cur cursor for SELECT currency, country
FROMinserted

OPEN cur
fetch cur into @currency, @country
WHILE @@FETCH_STATUS = 0
BEGIN
if not exists(select * from listinfoid where listname = 'currency' and listid = @currency)
begin
set @currency = (cast(@currency as varchar (3)) + ' is not a valid currency')
CLOSE cur
DEALLOCATE cur
RAISERROR (@currency,16,-1) with log
return
end
if not exists(select * from listinfoid where listname = 'country' and listid = @country)
begin
set @country = (cast(@country as varchar (3)) + ' is not a valid contry')
CLOSE cur
DEALLOCATE cur
RAISERROR (@country,16,-1) with log
return
end
else
fetch cur into @currency, @country

END
CLOSE cur
DEALLOCATE cur
update Client set currency = UPPER(currency), country = UPPER(country)
---------------------------------



I use a cursor to handle multiple rows in an update query.
(SQL2000-server)

Is there an easier och better way to do this?
I´m a bit unsure of this code.

Thanx!

Can't Insert New Data To Sql Using Sqldatasource.insert, Web Forms And A Master Page

Sep 11, 2006

Hello, I'm new to the forum and new to SQL, ASP.NET, etc.  I am creating an intranet site for my company in VS 2005 and have run into a very annoying problem that I can't seem to solve.  I have tried Googling it and came up empty.  I have a database in SQL Express 2005 and my website will be accessing several tables within the database.  I can retrieve info just fine and I can update, delete, etc just fine using gridview or other prebuilt tools, but when I add a few text boxes and wire a button to the SqlDataSource.Insert() command, I get a new record that is full of null values except for the identity key I have set.  The kicker is that I am also using a master page and when I duplicate the web page without the master page link, everything works just fine.  The following snippets show what I'm doing:<InsertParameters><asp:FormParameter Name="Name" Type="String" FormField="txtName" /><asp:FormParameter Name="Location" Type="String" FormField="ddlLocation" /><asp:FormParameter Name="Issue" Type="String" FormField="txtProblem" /></InsertParameters>Of course I match the formfields to the text boxes, create an onclick event for my button, the sqldatasource is configured correctly, it just doesn't work with the master page no matter what I do. Any help would be appreciated. Thanks

Using A Cursor To Check Data

Feb 1, 2008

Hi, here is my problem and hopefully somebody has an idea. What i am working on is an order tracking system. i insert the orders into sql then when the orders come in i check for the oldest order and apply the qty we recieved to that order...pretty simple. The problem is that some times we have 5 orders for the week and we then recieve them as one order so there will be 5 orders to fill. I can do this for 2 orders and was thinking about using a cursor to so this instead of a really drawn out procedure but am not sure how that would work if it would at all. Does anybody have any ideas?

To Check Range Of Data

Mar 23, 2006

Hi Guys,
Need your help on this problem.
Let say table name call tbl_range and 2 field call No1 and No2
I have this set of record :-
No1 No2
1000 2000
2001 3000
5000 6000

My problem, i want to check if user insert another set no No1 : 1500 No2 : 2500. So, this means that range already clash with another range. If this happened it will return 2 record (1000 - 2000) and (2001 - 3000). Can it be done and how?

Regards,
Shaffiq

Data Validation Check

Jan 31, 2008



I new here so hopefully I'm asking this question in the correct forum. I'm have a flat file that contains numbers that I need to verify that they begin with certain prefixes so they load to the correct client. For example in the flat file if I'm loading data for client A and their account numbers begin with 045XXXXXXX then it loads the data. But if there is a record that begins with 037XXXXXXX it should be loaded to client B instead and that records gets written to a error file.

So to summarize what I need , I'm looking for a check to kick out records if I'm loading client A's data versus if I'm loading client B's data.

Can this be done in a Conditional Split ?

Check Data Changes In Table

Oct 27, 2007

Hi all!
I need to check data changes in some tables from specified date. Can it be done without triggers for each table?
SQL Server Management Studio always says "Data was changed" if another user updates data and you try to update old version. How it checks data modification date? I found only this:


USE [ScheduleDB]

GO

SELECT * FROM sys.objects WHERE object_id = OBJECT_ID('[dbo].[TTest]') AND type in ('U')

but it can only show structure modification date.
