Comparing Null Values(from variable) in SSIS

Posted By:      Posted Date: September 03, 2010    Points: 0   Category :Sql Server
Hi All I need to create a script that checks to see if a variable value is NULL, if it is then it executes the next SQL Task and if not then the package has finished. I have this in a SQL 2000 DTS package script: Function Main() If isnull(DTSGlobalVariables("NextLoadDate")) Then Main = DTSStepScriptResult_DontExecuteTask Else Main = DTSStepScriptResult_ExecuteTask End if End Function As you can see, all I want to do is check to see if a variable is null then don't execute the next task. But i cannot get it to work in a SQL 2005 SSIS package, so far I have created a script and come up with the following: Public Sub Main() If Dts.Variables("NextLoadDate").Value.ToString <> "" Then Dts.TaskResult = Dts.Results.Success Else Dts.TaskResult = Dts.Results.Failure End If End Sub Any Ideas? Thanks BigGopher

Comparing columns with NULL values--Merge says unmatched when data is matched.

I found the article below describing this same issue with the Oracle merge statement.  It also described a work-around:    http://searchoracle.techtarget.com/tip/Merging-datasets-with-NULL-values I have been unable to find a solution to this issue for SQL Server 2008.  I am trying to do basic ETL from Staging table to a Type II dimension table in a Data Warehouse.  I am using the Merge statement with the Unique key minus the modification date as my merge key list.  I have a handful of columns (in both Staging and the DW) containing nulls in my merge key list.  I have tried the ISNULL function and the ANSI_NULL db option (OFF) with no success.  When I put zeros in the null columns, it works as expected.  I am about to try separate INSERT and UPDATE statements, but I fear that the NULL comparison issue will bite me there with the JOIN statement.  Has anyone else experienced this?  NULL values are valid in our Data Warehouse.  How can I make T-SQL handle them? Thank you for your help, Jesse

SSIS excel data source numeric values returned as null

Hello everyone, long time no see!, I have a problem and was hoping someone can help me:
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.

I tried the answer posted here: http://devselekta.blogspot.com/2007/09/ssis-excel-data-source-values-returned.html but it only works when the first row of data has a number beginning with zero on this column.
Someone knows how to get the data imported correctly? Thanks in advance.

How to deal with NULL values in a SQL table


 Hi all

In order to add/update/delete data from a table I build 2 classes: 1 class containing all the table fields and another class with methods to add/insert/update/delete records. I am learning how to avoid errors when your table must use SQL NULL values. One error is when I call my UPDATE method (see below):

  public void UpdateItem(OcItemConstraintDetails item)
  SqlConnection con = new SqlConnection(connectionString);
  SqlCommand cmd = new SqlCommand("ItemConstraints_Update", con);
  cmd.CommandType = CommandType.StoredProcedure;

  cmd.Parameters.Add(new SqlParameter("@itemConstraintId", SqlDbType.Int, 4));
  cmd.Parameters["@itemConstraintId"].Value = item.ItemConstraintId;

  cmd.Parameters.Add(new SqlParameter("@path", SqlDbType.NVarChar, 150));
  cmd.Parameters["@path"].Value = item.Path;

if you watch the SQL profiler trace you will see that I am passing a value of 'default' ;so that causes me problems.

exec ItemConstraints_Update @itemConstraintId=1,@path=default

With that said, what are the best practices when your SQL table accepts NULL values and when:
- you are passing an empty value to your stored procedure;

Help: Too many lines of code to achieve a simple goal: keep my NULL SQL values...


Hello all

What is the best way (best practice) to preserve my NULL SQL values in the database
during an insert/update operation (without receiving cast invalid errors)?
Also, how to display a string 'n/a' when a sql value is NULL?

My project is using FormView with Edit/Insert templates and classes to represent my tables

Goal1....: display 'n/a' when there are NULL SQL values in the database
Solution1: I am using ISNULL(field,'') in my store procedure for SELECT statements

Goal2....: if the fields are 'n/a', then save them back in the database as NULL
Solution2: on my insert/edit methods I am having to check the values being passed, i.e:

cmd.Parameters.Add(new SqlParameter("@scope", SqlDbType.NVarChar, 50));

if (item.Scope == "n/a")
 cmd.Parameters["@scope"].Value = DBNull.Value;
 cmd.Parameters["@scope"].Value = item.Scope;

Not to mention that for SQL DateType fields when you use ISNULL(field,'') the return string is '1/1/1900 12:00:00 AM'
and I have to change the field value in every field that represents a date, i.e:

protected void FormView1_DataBound(object sender, Sy

SSIS Deployment Reads local Environment Variable and not Server

Hi All, I have an SSIS package that uses an Environment variable to hold the connection string for the local SSISConfiguration table.  This works properly on my local machine.  However, when I import the package to Integration Services(through SSMS) it reads the environment variable from the local machine and not the server it is deployed to.  If I log on to the server remotely and do the same process it uses the the correct environment varible... (SQL Server 2005) Is there a way to deploy the package to the server and get it to use the correct Env variable without having to log-in to the server and import it?  Let me know if anyone is looking for additional information.   Thanks!

SSRS Report based on SSAS Cubes doesn't show NULL values correctly

I have a SSRS report which is based on an SSAS Cube. In the Cube the formating of numeric fields that NULL values are properly shown as NULL values. In the Cube Browser and Excel this is shown correctly. However when I design the report already the query against SSAS shows these fields as "0" instead of NULL. Is there a way to fix this or is this a bug ?

Multiple Values to the Variable, HOW?

Hi All, I'm trying below query which is working fine:- DECLARE @FULLNAME VARCHAR SET @FULLNAME = 'PQR, ABC L.' SELECT ID FROM TABLE-NAME WHERE LAST_NAME = SUBSTRING(@FULLNAME, 1, PATINDEX('%,%', @FULLNAME) -1) AND FIRST_NAME = LTRIM(RTRIM(SUBSTRING(@FULLNAME, PATINDEX('%,%', @FULLNAME)+1 , PATINDEX('% %', @FULLNAME)))) But when I include two values to the same variable something like this:- DECLARE @FULLNAME VARCHAR SET @FULLNAME = 'PQR, ABC L.', 'LMN, XYZ' SELECT ID FROM TABLE-NAME WHERE LAST_NAME IN SUBSTRING(@FULLNAME, 1, PATINDEX('%,%', @FULLNAME) -1) AND FIRST_NAME IN LTRIM(RTRIM(SUBSTRING(@FULLNAME, PATINDEX('%,%', @FULLNAME)+1 , PATINDEX('% %', @FULLNAME)))) It is giving me error as:- "Incorrect syntax near 'SUBSTRING'." This is because my @FULLNAME will be an SSRS report parameter and which is going to be multi-value parameter. Any Help Please? Thanks Regards, Kumar
