Integration Services :: SSIS Insert Non Null Value Into Null Rows

Jul 15, 2015

I have a flat file with the following columns

SampleID   Rep_Number   Product  Protein   Fat   Solids

In the flat file SampleID and Product are populated in the first row only, rest of the rows only have values for Rep_Number, Protein, Fat, Solids.

SampleID and Product are blank for the rest of the rows. So my task is to fill those blank rows with the first row that has the sampleID and Product and load into the table.

Integration Services :: Excel Source On SSIS 2008 Brings Null Values

Apr 20, 2010

I'm trying to import some XLS files that I receive from some suppliers. The problem is that every time they send some columns with text values but formatted as number. When I read those columns with SSIS Excel Source, they come all with null values.

I don't want to change the columns data types every time, so I would like to know if there's a way to bypass the column types that are already there.

I tried to use both the Jet driver and the Office 12 driver. I've already used the IMEX=1 on ExtendedProperties too with no success. Is there a way to force reading the columns as text, even if they have data types assigned to them?

Integration Services :: SSIS Excel Data Source Numeric Values Returned As Null

May 8, 2009

I'm using SSIS 2005 Enterprise edition,  I'm creating a package that reads an excel (xls) file using the "excel source" component, and it dumps the data into an OLEDB destination (a sql server). When I drag the excel source component and create the excel connection to my file the component automatically reads the columns and their datatypes.

The problem is that I have a column which has numeric data and the package uploads as NULL every number that starts with a zero. (note: in excel this column is formatted as "text", despite it has only numbers, because it's the only way excel maintains the left sided zeros).

So I checked the data types by right clicking the excel source component -> show advanced editor and my surprise is that this column's data type is detected as double-precision float, and it doesn't let me change it. URL... but it only works when the first row of data has a number beginning with zero on this column. How to get the data imported correctly?

Integration Services :: Delete And Insert Rows In Access From SSIS Package

Sep 4, 2015

I have a ssis package which identifies duplicate records in access database. I have staged access database into sql sever and created ssis package. Now, I have final list of records which needs to be delete from access database and new records which are to be inserted into access database. 

What do I need to do if I want to delete those duplicate records directly from access database using SSIS. I cannot truncate whole access database and reload. I just have to delete duplicate rows from access db and add new records.

Integration Services :: Excel Column Turns To Blank / NULL While Import Using SSIS Excel Source 2008

Jul 6, 2015

While importing data from Excel source , some column is getting null value even though excel column has value.To Resolve the issue we tried with

1.Change the Value  of the Row TypeGuessRows from 8 (Default value) to 0  and ImportMixedType = text

• xls
HKEY_LOCAL_MACHINESOFTWAREMicrosoftJet4.0EnginesExcel

1.Change the Value  of the Row TypeGuessRows from 8 (Default value) to 0  and ImportMixedType = text

the connection string of the excel

UPPER(REVERSE(SUBSTRING( REVERSE(@[User::VarInputExcelFile]), 1, 5) ) ) == ".XLSX" ? "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + @[User::VarInputExcelFile] + ";Extended Properties="Excel 12.0;HDR=Yes;IMEX=1";":"Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=" + @[User::VarInputExcelFile] + ";Extended Properties="EXCEL 8.0;HDR=Yes;IMEX=1";"

by doing the above setting also , the column is coming as null from excel source even though there is data in excel.

Integration Services :: SSIS Package - Replacing Null Values In One Column With Values From Another Column

Sep 3, 2015

I have an SSIS package that imports data from an Excel file, replaces any value in Excel that reads "NULL" to "", then writes the data to a couple of databases.

What I have discovered today, is I have two columns of dates, an admit date and discharge date column, and what I need to do is anywhere I have a null value in the discharge date column, I have to replace it with the value in the admit date column. 

I have searched around online and tried a few things using the Replace funtion in Derived columns but no dice so far.

Integration Services :: Empty String Is Showing As NULL Value In Database?

Oct 8, 2015

In my source table, I have columns FirstName and LastName, both of datatype nvarchar. In my dataflow, I created two new derived columns mapped to these two columns. When pushing data to the source, I noticed that the FirstName column had a value of NULL while LastName was just an empty string (for rows that did not have any value).

My question is, why my source table column FirstName is showing a NULL value when the derived column datatype is string and the source is string? It should just be showing an empty string right?

Problem With Isnull. Need To Substitute Null If A Var Is Null And Compare It To Null And Return True

Sep 20, 2006

Hey. I need to substitute a value from a table if the input var is null. This is fine if the value coming from table is not null. But, it the table value is also null, it doesn't work. The problem I'm getting is in the isnull line which is in Dark green color because @inFileVersion is set to null explicitly and when the isnull function evaluates, value returned from DR.FileVersion is also null which is correct. I want the null=null to return true which is why i set ansi_nulls off. But it doesn't return anything. And the select statement should return something but in my case it returns null. If I comment the isnull statements in the where clause, everything works fine. Please tell me what am I doing wrong. Is it possible to do this without setting the ansi_nulls to off??? Thank you

set ansi_nulls off


go

declare

@inFileName VARCHAR (100),

@inFileSize INT,

@Id int,

@inlanguageid INT,

@inFileVersion VARCHAR (100),

@ExeState int

set @inFileName = 'A0006337.EXE'

set @inFileSize = 28796

set @Id= 1

set @inlanguageid =null

set @inFileVersion =NULL

set @ExeState =0

select Dr.StateID from table1 dR

where

DR.[FileName] = @inFileName

AND DR.FileSize =@inFileSize

AND DR.FileVersion = isnull(@inFileVersion,DR.FileVersion)

AND DR.languageid = isnull(@inlanguageid,null)

AND DR.[ID]= @ID

)

go

set ansi_nulls on

After SSIS Package Runs All Rows, All Fields Are NULL In Destination Table ???

Jul 21, 2007

I am copying a simple table from a Sql Server 2005 database to an *.sdf mobile database.

I am brand new to SSIS and I am probably doing something wrong. But after executing the SSIS package all the rows and all the fields are NULL in the destination database. I put a datagrid viewer between the OLE DB Source and the Sql Server compact edition destination and I can see the real data which is obviously not ALL NULL.



Does anyone have a clue as to why it would be doing this?





Any help would be much appreciated.



Thanks...

Compressing Multiple Rows With Null Values To One Row With Out Null Values After A Pivot Transform

Jan 25, 2008

I have a pivot transform that pivots a batch type. After the pivot, each batch type has its own row with null values for the other batch types that were pivoted. I want to group two fields and max() the remaining batch types so that the multiple rows are displayed on one row. I tried using the aggregate transform, but since the batch type field is a string, the max() function fails in the package. Is there another transform or can I use the aggragate transform another way so that the max() will work on a string?

SSIS Tries To Insert NULL Value Into A Destination Column Ignored In The Mapping.

Jan 12, 2008

Hello everyone,

I am having a little problem with a simple package and I do not know if this is a known issue or that I am missing something.

I have a data flow task, a simple one, with an oledb source pulling data, using a select statement, from a sql server 2005 instance, and an ole db destination pointing to a table in a sql server 2000 instance. Both intances are standard edition. The table in the destination has a column which allow null values and has also a default constraint (getdate()), and this column is not present in the source. When I map the columns in the destination, I leave this column as "ignore", not being mapped to any column from the source. The problem is that when I execute the task, SSIS is trying to insert NULL value into this column, so the package fail with the error "can not insert NULL value into column myColumn". I wonder why is it trying to insert NULL value if the column is not mapped to any column from the source.

Is this a known issue or I am nissing something in the settings?

If the destination table has rowversion or identity columns, there is no problem ar all. I ignore those columns in the mapping and SQL Server feeds them as expected.

Thanks in advance,
Alejandro Mesa

SSIS Script Source Destination Insert Null Columns

Dec 1, 2006

Hi I have an SSIS package that retrieves table data from a database using an OLE DB source component.

This then passes the rows of data to a script destination component.

Within this script my code takes the row data and inserts it into the database (amongst other things).

However I have noticed that if any of the Row columns contain nulls then the component falls over with errors when run like so:

[Back Up Prize Banks [2875]] Error: System.Data.SqlClient.SqlException: Parameterized Query '(@PASId int,@ScriptName nvarchar(17),@LastModified datetime,@Pri' expects parameter @RegenerateXML, which was not supplied. at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.HandleUserException(Exception e) at Microsoft.SqlServer.Dts.Pipeline.ScriptComponentHost.ProcessInput(Int32 inputID, PipelineBuffer buffer) at Microsoft.SqlServer.Dts.Pipeline.ManagedComponentHost.HostProcessInput(IDTSManagedComponentWrapper90 wrapper, Int32 inputID, IDTSBuffer90 pDTSBuffer, IntPtr bufferWirePacket)

I have solved the problem by checking the column contents before inserting it as follows:

Before:
Command.Parameters.AddWithValue("@RegenerateXML", Row.RegenerateXML)

After:
If (Row.RegenerateXML_IsNull()) Then
Command.Parameters.AddWithValue("@RegenerateXML",System.DBNull.Value)
Else
Command.Parameters.AddWithValue("@RegenerateXML", Row.RegenerateXML)
End If

Which is great but it does turn 1 line into 5 lines. I have 20 parameters which takes up 20 lines of code which will now be 20 x 5 = 100 lines of code.

My question is :

Is there a better way to write this code without having to take up so many lines?

Thanks

Matt.

Integration Services :: Package Does Not Insert All Rows

Aug 12, 2015

I'm working with integration services 2008 and I have a package where I selected a certain set of rows from an Oracle database and then I insert this data set into a SQL database. When the package is inserting in SQL database, it shows that all the rows were inserted, "green", but when I check the amount of data (I count), it's not the same as it was in Oracle.

For example: there are 15390 rows in Oracle and the packages inserts sometimes 9801, 8310, 9952, 9934, 9975, 5437, 9909 rows in SQL server.The package does not abort! It simply does not insert all the rows!

Integration Services :: SSIS Data Transfer Says Rows Copied But Count On Table Is Less?

Sep 18, 2015

I've a SSIS 2008  parent/child package solution to manage data transfers between two different data sources, so we can copy multiple tables and capture how many rows were transferred and duration for each transfer.  This solution was working fine up until last week, when I made some changes to allow the package to perform a source count using standard SQL determined by an expression, or SQL provided from configuration tables, I also changed the package to Truncate or not the destination table, again controlled by configuration settings in a table. The child packages which perform the data flows have not changed!

The day after the controlling package promotion to live, I saw the bizarre behaviour of the Package log stating all rows transferred, but the actual table counts were not what the log stated, see attached file. The package solution works ok on other servers and was ok in DEV, but there were less tables and rows transferred.Re-running the package gave the same errors, but on some of the same tables and some different ones. 

As it is the child packages doing the transfers and nothing has changed in them. I cannot see how the log would be able to say all rows are transferred and yet not all of the rows are actually moved?

Process output - where you can see counts and log Table transfer controller (as txt not dtsx)

An example of the data transfer child packages (as txt not dtsx)When I set the ExecuteOutOfProcess = True the package worked fine, unfortunately, this is not a good solution as SSIS 2008 does not tidy up the Dtshost.exe processes it starts and I'd be left with a memory issue after a very short time, we transfer hundreds of tables each day. ( I could write a .net script in the controlling package to kill the child processes, but that would still have hundreds of processes running before I could end them, as we have three parallel streams to allow a bit better performance.

Subscription Issue With Null Default Parameter - Key Cannot Be Null

May 3, 2007

I have a report that is run on a monthly basis with a default date of null. The stored procedure determines the month-end date that it should use should it be sent a null date.

The report works fine when I tell it to create a history entry; however, when I try to add a subscription it doesn't appear to like the null parameter value. Since I have told the report to have a default value of null it doesn't allow me to enter a value on the subscription page.

Now, I suppose I could remove the parameter altogether from the stored proc, but then the users would never be able to run the report for a previous time period. Can someone explain to me why default values aren't allowed to be used on subscriptions when they seem to work fine for ad hoc and scheduled reports? This is really quite frustrating as most of my reports require a date value and default to null so that the user doesn't have to enter them for the latest data.



An internal error occurred on the report server. See the error log for more details. (rsInternalError) Get Online Help




Key cannot be null. Parameter name: key

Returned SQLParam.SqlValue Is {Null} But Can't Test For Null?

Nov 5, 2007

I run a stored procedure for which I have a return variable. The stored procedure returns the ID of a row in a table if it exists:

m_sqlCmd.ExecuteScalar();

The m_sqlCmd has been fed an SQLParameter with direction set to output.
When the stored proc returns, I want to test it. Now when there IS a row it returns the ID ok.
When the row doesn't exist, in my watch I have:

m_sqlParam.SqlValue with value {Null}

I can't seem to work out how to test this value out.
I've tried several things but none seem to work.

This line compiles ok, but the following runs into the IF statement as if the SqlValue is null??

if (m_sqlParam.SqlValue != null)....
{

// I'm here!! I thought the watch says this is null???
}

Sorry if this is obvious, but I can't work this one out!!
