Force Execution On Import -- Ignore Duplicates
Jun 7, 2006
I have a simply SSIS package with following data flow structure:
Flat File Source > Data Conversion > Aggregate > Dervied Column > Ole dB Destination
Basically, this package is executed on daily basis to import sales from a text file into sql server. Now there's a possibility that text file may contain previous sales (occasionally).
My sql table structure enforces data integrity through primary key and therefore my package errors out if there's a duplicate in text file which already exists in sql server.
I'm basically looking for a way to ignore these duplicates and continue to import rest of the file. I need a way to force execution (suppress errors if possible) and finish importing all text file.
I've tried making the maximumerrorcount more than # 50000 and failparent/failpackage on error = false.
Any help is greatly appreciated...thanks
Here's the errors I receive:

Hello - the very nature of this question seems to make no sense I know - but we received a huge volume of data (29 tables) in flat file format. I first imported them into MS Access because of its portability and it seemed to be more forgiving on imports. Now I have a complete MS Access DB with all tables, so I figured importing to SQL server should be a snap. However, on the import, I had 14 tables import successfully, and 15 failed!
Here is an example of one of the error messages I received:
Insert Error, Column 3 - status 6; Data Overflow...this was on a date/time field in access, and here is the data contained in the referenced row/column: "8/19/4999"
the year "4999" is obviously the problem (at least i think), and I have no idea why this successfully imported to MS Access, but not to SQL Server....
what i'd like to be able to do (not the best practice, i know) for now is ignore these types of errors - and just force SQL server to take the data straight from MS Access and replicate it. We received this data from a 3rd party, and there's no telling how many data entry errors like this could be in each table - many of the tables have over 500,000 rows, and i don't want to have to go through fixing each of these errors by hand...anyone have any ideas?

Hi,
I have a big table and want to make a plausibility check of itīs data.
Problem is, that my query stops, if there is an unexpected datatype in one of the rows. But that is it, what i want to filter out of my table with that query and save the result as new correct table.
How can i write a parameter to my query SQL Code, that if a error occurs, the querry resumes and the error line will not displayed in my final querry overview?
In my books and on the net, i donīt found something to this theme ;-(.
Thx in advance.

What happens when you add the Ignore Case flag into the mix?
I'm having a hell of a time - I'm dealing with an SCD situation using TableDifference component and I have both existing dimensions and new data coming in, each go through identical Case-Insensitive/Sort with remove duplicates, but I'm getting identical new and deleted records detected - I think because of ordering issues. I'm still trying to whittle the test case down, but I think data from all around the records I'm investigating seems to get sorted in between them, so I'm having trouble getting a small test case built.
I think the mixed case data is the root of the problem, and I think the design is bad, but before I go back to the technical lead, I need to understand enough to show that you cannot take two pipelines sorted and de-duped case-insensitively and then do a case-sensitive table difference operation.

I have another post here regarding SQL 2005 running a query 50% slower than on 2000. It was discovered that 2005 runs the query in series whereas 2000 runs it in parallel.
Even with "Cost Threshold For Parallelism" set to a default value â 0, 2005 still executes my query in series. Does anyone know how to force a query to run in parallel in SQL 2005. I specifically want to set it at the database level.

I have an ssis package with three tasks. I want to force the execution result of the package to success all the time. I execute the package from a .net application. I tried to place my tasks in the package inside a sequence container and created a new script task which would execute when the any of the tasks in the container failed. I am setting the result of the package to success in this script task. This is not correctly working for me. Even if one task in the package failed and the last script task went to success, the .net app is receiving a failure status. Is there any way to handle this in the ssis package than in the .net app. There might be an easy way, but I am unable to find it.
Thanks in advance!!

I have an SSIS package that imports from an Excel file with data beginning in the 7th row.
Unlike the same operation with a csv file ('Header Rows to Skip' in Connection Manager Editor), I can't seem to find a way to ignore the first 6 rows of an Excel file connection.
I'm guessing the answer might be in one of the Data Flow Transformation objects, but I'm not very familiar with them.
Any pointers would be greatly appreciated.

I'm new to SSIS, and trying to automate data imports from text files. The text files I'm importing always contain a fixed set of columns, or a subset of those columns. If I include a subset of columns in the import file (and exclude others), the data doesn't import...I assume because the actual file doesn't include every column defined in the flat file source object?
Is it possible to accomplish this without dynamically selecting the columns, as indicated here: http://msdn2.microsoft.com/en-us/library/ms136020.aspx

I know that this almost never happens... but Im dealing with an AIX flatfile-database conversion that brings 80 tables into SQL. Im not allowed to touch this stuff or to massage how its brought over to SQL, as it deals with medical records...
What I need to do though, is on creating my own table imports, for my "account" fields to match with the existing SQL conversion table "account" fields, I have to match requirements...
Existing account numbers are a total of 6 charaters. Account numbers with less than six characters contain leading whitespace character equivalents to total the six character spaces for "account number"
When I import records, I need to force the same requirement and have a min and max length of characters for "account number" = 6 characters and any account number less than 6 characters must also have the necessary whitespace character equivalent added to it.
How would I do this? It needs to be automated, as this is a process that will run nightly and cannot have a human sitting on it every day, 7 days a week... I cannot accurately join unless I can meet this requirement and my hands are tied because I can't change the way the formatting is done on the imported tables =(
Any help would be greatly appreciated... I'm quite stuck

Hi
I am currently trying to import data from a table in 1 database into a table of the same name in another database. This in it's self is simple, however to add a twist to the proceedings there is data that exists in both tables. I just want to import the data that doesn't exist in the table I am importing into.
Please can you advise as to the best method to use
Many thanks

I have a table with 22 million Business records. I can see that there are duplicates when I group by BusinessName and Address and Phone. I'd like to place only the duplicates into a table, with a ranking, oldest business key gets a ranking of 1.
As a bonus I'd like each group to have a distinct group name (although not necessary, just want to know how to do this)
Later after I run more verifications to make sure these are not referenced elsewhere I'll delete everything with a matchRank > 1 out of the main Business table.
DROP TABLE [dbo].[TestBusiness];
GO
CREATE TABLE [dbo].[TestBusiness](
[Business_pk] INT IDENTITY(1,1) NOT NULL,
[BusinessName] VARCHAR (200) NOT NULL,
[Address] VARCHAR(MAX) NOT NULL,
[code]....

after moving off VS debugger and into management studio to exercise our SQLCLR sp, we notice that the 2nd execution gets an error suggesting that our static SqlCommand object is getting reused from the 1st execution (of the sp under mgt studio). If this is expected behavior, we have no problem limiting our statics to only completely reusable objects but would first like to know if this is expected? Is the fact that debugger doesnt show this behavior also expected?

Hi I am slowly getting to grips with SQL Server. As a part of this, I have been attempting to work on producing more efficient queries. This post is regarding what appears to be a discrepancy between the SQL Server execution plan and the actual time taken by a query to run. My brief is to produce an attendance system for an education establishment (I presume you know I'm not an A-Level student completing a project :p ). Circa 1.5m rows per annum, testing with ~3m rows currently. College_Year could strictly be inferred from the AttDateTime however it is included as a field because it a part of just about every PK this table is ever likely to be linked to. Indexes are not fully optimised yet. Table:CREATE TABLE [dbo].[AttendanceDets] ([College_Year] [smallint] NOT NULL ,[Group_Code] [char] (12) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,[Student_ID] [char] (8) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ,[Session_Date] [datetime] NOT NULL ,[Start_Time] [datetime] NOT NULL ,[Att_Code] [char] (1) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL ) ON [PRIMARY]GO CREATE CLUSTERED INDEX [IX_AltPK_Clust_AttendanceDets] ON [dbo].[AttendanceDets]([College_Year], [Group_Code], [Student_ID], [Session_Date], [Att_Code]) ON [PRIMARY]GO CREATE INDEX [All] ON [dbo].[AttendanceDets]([College_Year], [Group_Code], [Student_ID], [Session_Date], [Start_Time], [Att_Code]) ON [PRIMARY]GO CREATE INDEX [IX_AttendanceDets] ON [dbo].[AttendanceDets]([Att_Code]) ON [PRIMARY]GOALL inserts are via an overnight sproc - data comes from a third party system. Group_Code is 12 chars (no more no less), student_ID 8 chars (no more no less). I have created a simple sproc. I am using this as a benchmark against which I am testing my options. I appreciate that this sproc is an inefficient jack of all trades - it has been designed as such so I can compare its performance to more specific sprocs and possibly some dynamic SQL. Sproc:CREATE PROCEDURE [dbo].[CAMsp_Att] @College_Year AS SmallInt,@Student_ID AS VarChar(8) = '________', @Group_Code AS VarChar(12) = '____________', @Start_Date AS DateTime = '1950/01/01', @End_Date as DateTime = '2020/01/01', @Att_Code AS VarChar(1) = '_' AS IF @Start_Date = '1950/01/01'SET @Start_Date = CAST(CAST(@College_Year AS Char(4)) + '/08/31' AS DateTime) IF @End_Date = '2020/01/01'SET @End_Date = CAST(CAST(@College_Year +1 AS Char(4)) + '/07/31' AS DateTime) SELECT College_Year, Group_Code, Student_ID, Session_Date, Start_Time, Att_Code FROM dbo.AttendanceDets WHERE College_Year = @College_YearAND Group_Code LIKE @Group_CodeAND Student_ID LIKE @Student_IDAND Session_Date <= @End_DateAND Session_Date >=@Start_DateAND Att_Code LIKE @Att_CodeGOMy confusion lies with running the below script with Show Execution Plan:--SET SHOWPLAN_TEXT ON--Go DECLARE @Time as DateTime Set @Time = GetDate() select College_Year, group_code, Student_ID, Session_Date, Start_Time, Att_Code from attendanceDetswhere College_Year = 2005 AND group_code LIKE '____________' AND Student_ID LIKE '________'AND Session_Date <= '2005-11-16' AND Session_Date >= '2005-11-16' AND Att_Code LIKE '_' Print 'First query took: ' + CAST(DATEDIFF(ms, @Time, GETDATE()) AS VarCHar(5)) + ' milli-Seconds' Set @Time = GetDate() EXEC CAMsp_Att @College_Year = 2005, @Start_Date = '2005-11-16', @End_Date = '2005-11-16' Print 'Second query took: ' + CAST(DATEDIFF(ms, @Time, GETDATE()) AS VarCHar(5)) + ' milli-Seconds'GO --SET SHOWPLAN_TEXT OFF--GOThe execution plan for the first query appears miles more costly than the sproc yet it is effectively the same query with no parameters. However, my understanding is the cached plan substitutes literals for parameters anyway. In any case - the first query cost is listed as 99.52% of the batch, the sproc 0.48% (comparing the IO, cpu costs etc support this). BUT the text output is:(10639 row(s) affected) First query took: 596 milli-Seconds (10639 row(s) affected) Second query took: 2856 milli-SecondsI appreciate that logical and physical performance are not one and the same but can why is there such a huge discrepancy between the two? They are tested on a dedicated test server, and repeated running and switching the order of the queries elicits the same results. Sample data can be provided if requested but I assumed it would not shed much light. BTW - I know that additional indexes can bring the plans and execution time closer together - my question is more about the concept. If you've made it this far - many thanks.If you can enlighten me - infinite thanks.

Hello Everyone,
When i checked the machine this morning i saw that MS DTC service was stopped and when did start it, it was good for a sec or two then it stopped auto matically i was not sure waht was goin on...
Then i checked the Eventviewer, it said the log file is full i tried out to find ms dtc log reset or increase the size but could not find out..where can i find this.
One more thing what is the purpose of DTC, i know in sql 6.5 we have everything in enterprize manager but i can't see the same either in 7.0 or 2000 is the name changed or is it linked to some other source.
Like linked server , does this depend on MS DTC..how and what is the basic purpose of this..kindly tell me what i should do now...
I got to fix it asap..big hassle..
Thanks in advance,

For a few rows I get a"right truncation" error and the offending rows are not uploaded to thetable.I don't want to increase the size of the table varchar fields becauseit's only about a dozen out of almost million rows that have thisproblem ... I want to provide an override - i.e. if a row will resultin truncated data, truncate but still bulk copy the offending row. Isthat possible?I couldn't find such an option in the documentation.Any help is greatly appreciated.Thanks,Mudassir Latif

I'm writing a store procedure to accept search strings from user on my site. Currently, this is what I have.
Code Snippet
@schoolID int = NULL,
@scholarship varchar(250) = NULL,
@major varchar(250) = NULL,
@requirement varchar(250) = NULL
--@debug bit = 0
AS
BEGIN
-- SET NOCOUNT ON added to prevent extra result sets from
-- interfering with SELECT statements.
SET NOCOUNT ON;
SELECT * FROM [scholarship]
WHERE ([sectionID] = @schoolID OR @schoolID IS NULL)
AND ([schlrPrefix] LIKE '%' + @scholarship + '%' OR [schlrName] LIKE '%' + @scholarship + '%' OR [schlrSufix] LIKE '%' + @scholarship + '%' OR @scholarship IS NULL )
AND ([Specification] LIKE '%' + @major + '%' OR @major IS NULL )
AND ([reqr1] LIKE '%' + @requirement + '%' OR [reqr2] LIKE '%' + @requirement + '%' OR [reqr3] LIKE '%' + @requirement + '%' OR [reqr4] LIKE '%' + @requirement + '%' OR [reqr5] LIKE '%' + @requirement + '%' OR @requirement IS NULL )
The problem is, somtimes the search doesn't work if there is a space behind or infront of the search string. I wonder if there is away to ignore any spaces and go right into whatever character comes next or after. If so, how do I implement that?

I have a stored procedure that does several steps.
During the stored proc, error messages are produced when certain conditions warrant. But I want to continue anyway....
ex. in a loop in the proc...
SET @strSQL = 'Update Table1 SET col1 = ''' + @strVariable + ''''
EXEC (@strSQL)
--ERROR created by the exec statement.....
When I schedule this as a job, the first error message makes the job fail.
How can I force the proc to run completely, even if an error occurs?
Thanks in Advance..

Hi! I'm wondering if there is a way to have the AVG() not to include the zero amount as part of the calculation. I'm looking
the field, PurchPrice and RepairCost that are used by the AVG() function...
Code:
SELECT Year, MakeID, ModelID, Style, AVG(PurchPrice), AVG(RepairCost)FROM vwAvgPurchase
WHERE StockDate >= (GETDATE()- 365)
GROUP BY Year,MakeID,ModelID, Style
I don't want to do this way...
Code:
SELECT Year, MakeID, ModelID, Style, AVG(PurchPrice), AVG(RepairCost)FROM vwAvgPurchase
WHERE StockDate >= (GETDATE()- 365)
and (PurchPrice > 0 or RepairCost > 0)
GROUP BY Year,MakeID,ModelID, Style
because the PurchPrice would sometime be zero and the RepairCost wouldn't be zero.

Hi,
I have 2 tables in which there are 2 fields which hold the same piece of data. In one of the fields however there is a "_" character within the value.
So when comparing the 2 directly they will not be the same.
So the example is the following
Table 1, field 1 value is 1000220_1
Table 2, field 2 value is 10002201
So in table 1 the "_" is always in the 8th position.
Does anybody know a way in the JOIN statement how I can maybe ignore the 8th character in field 1 ? Or ignore any "_" it finds?
Any help is appreciated!
Thanks,
Michiel

Hi,
I am trying to import data from a Text file into a database Table using SQLserver BCP utility. I am able to do that when I have all new records in my Text file. But I am getting primary key violation error when I am trying to import the record which is already existing in the table. This is correct, but I want my program to ignore these errors and import only those records which are fine.
I tried [-m maxerrors] option, but it is not working. My BCP program is getting interrupted at the first error itself, even if I give [-m100] option.
my command looks something like this,
bcp pub..employee in C:data.txt -b1 -m100 -c -t, -Sdatabase -Uuser -Ppassword
here -b1 is, processing 1 row per batch transaction
-m100 is, ignoring first 100 errors
please help.
thanks
